We carried out this study with the aim of evaluating the determinants of early survival of women with breast cancer in two hospitals in the city of Yaoundé. Methodology: This was an analytical cross-sectional study with retrospective and prospective data collection of breast cancer patients during 6 years in two Hospitals of Yaoundé from January 2017 to December 2022. We consulted the files in search of epidemiological, clinical, paraclinical, therapeutic and survival variables. We completed the survival data directly from the patients or their relatives after their consent. We analyzed the data using SPSS version 23.0 software. Survival analysis was done using the Kaplan-Meier method and survival curves were compared using the Log Rank test. Factors influencing survival were evaluated using the Cox model. The significance threshold (P value) was set at 0.05 at 95% confidence interval. The study was approved by the ethics committees. Results: We included 500 patients whose ages varied between 22 and 83 years with a mean age of 47.19 ± 11.61 years. The most represented age group was 30 to 45 years old (45.8%). Less than half (41.6%) were postmenopausal. The most frequent reason for consultation was a breast lump (79.9%). The most common clinical stage at presentation was stage-3 (47.6%). Infiltrating ductal carcinoma was the most represented histological type (84.7%). The most represented histological grade was grade 2 (40.2%). Immunohistochemistry was performed in 34.20% of cases. The most represented molecular subtype was triple negative (41.8%) followed by Luminal A (30%). Concerning treatment, 17.2% did not receive any, 45% had surgery, 79.4% had chemotherapy, 34.2% hormone therapy, and 14.6% radiotherapy. The survival of patients with breast cancer at 1, 2, 3, 4 and 5 years was respectively 90.6%;83.1%;74.2%;69.8% and 59.2%. The median survival was not reached;however, the first quartile (Q1) was 36 months (3 years). Independent factors associated with reduced survival were breast ulceration (aHR = 3.23;p = 0.002), bilateral tumor location (aHR = 9.2;p < 0.001) and clinical stage 3 (aHR = 1.72;p = 0.010) while patients classified ACR3 on imaging (aHR = 0.19;p = 0.005) had improved survival. Conclusion: Breast cancer survival from 1 to 5 years decrease from 90 to 59%. Mortality was highest in the first 40 months. Independent factors associated with reduced survival were breast ulceration, bilateral tumor location and clinical stage 3 while patients classified ACR3 on imaging had improved survival.展开更多

Breast cancer incidence increases annually due to the aid of established screening programs, leading to the discovery of breast cancer in its early stages. Surgical treatment is an integral part of early breast cancer management to achieve local control. Axillary surgical interventions such sentinel lymph node biopsy (SLNB) and axillary lymph node clearance (ALND) aim to stage the axilla as an adjunct to the management of the primary breast tumor. In this paper, we reviewed female breast cancer patients aged 30 - 60 who underwent surgical treatment of SLNB and/or ALND with reporting the prevalence of lymphedema and other associated complications and risk factors. Methodology: A cross-sectional non-interventional study, with a sample size of 250 including breast cancer cases from 2016 to 2019 at National Guard Hospital (NGH) in Jeddah, Saudi Arabia. Results: A total of 253 breast cancer cases were included in this study, with a mean age of 53 years, 52.7% were postmenopausal and positive family history was present among 21% of cases. Further, 90.9% of the cases had unilateral disease. Staging was as follows: stage I 14.5%, stage II 45.2%, stage III 37.1%, and stage IV 3.2%. Mastectomy was done in 73.4% cases and lumpectomy was performed in 34.1% of cases. In addition, 93.3% of patients had SLNB and 49% of them were positive. Axillary dissection was performed in 69.6% of our patients. Radiotherapy and chemotherapy were given to 71.8% and 80.4% of cases respectively. Among the chemotherapy (chemo) recipients, 40.2% received adjuvant chemo, 54.5% received neoadjuvant chemo, and the remaining 5.3% received both. Further, the most prevalent complication was pain accounting for 42.1% of total complications, and the least prevalent was cellulitis 4%. Also, seroma developed in 18.3% cases, paresthesia noted in 5.6% of cases, winged scapula was reported as 2%, weakness and necrosis were seen in 6% and 13.1% of cases respectively. Axillary vein thrombosis and lymphangiosarcoma were reported in none of the patients (0%). Lymphoedema accounted for 16.1% of overall complications, 85% of the patients who developed lymphedema had undergone ALND, and 12.9% and 14.4% received radiotherapy and chemotherapy respectively. Lymphedema was observed in breast cancer stages as follows: stage I 1.2%, stage II 7.2%, and stage III 5.2%. Patients with body mass index (BMI) of 30 - 39 kg/m<sup>2</sup> had 7.2% prevalence of lymphedema compared to other BMI groups. Overall mortality was 8.3%. Conclusion: The findings of our study suggest that the prevalence of lymphedema was higher in ALND patients with locally advanced tumors, and higher BMI, compared to patients with stage I breast cancer and low BMI. Further, the prevalence of lymphedema in patients who underwent ALND was significantly lower than those who were treated by lumpectomy 10.3% (p-value = 0.034) in comparison to mastectomy 19.3%.展开更多

However, subgroup survival data from a large study sample are limited in China.To estimate the survival differences among patients with different stages and various subtypes of breast cancer, we conducted a hospital-based multi-center study on breast cancer in Beijing, China.Methods: All resident patients diagnosed with primary, invasive breast cancer between January 1,2006 and December 31,2010 from four selected hospitals in Beijing were included and followed up until December 31,2015. Hospitalbased data of stage at diagnosis, hormone receptor status, and selected clinical characteristics, including body mass index(BMI), menopausal status, histological grade, and histological type, were collected from the medical records of the study subjects. Overall survival(OS) and cancer-specific survival(CSS) were estimated. Cox proportional hazards models were employed to evaluate the associations of stage at diagnosis and molecular subtype with patient survival.Results: The 5-year OS and CSS rates for all patients were 89.4% and 90.3%. Survival varied by stage and molecular subtype. The 5-year OS rates for patients with stage I, Ⅱ, Ⅲ, and IV diseases were 96.5%, 91.6%, 74.8%, and 40.7%,respectively, and the corresponding estimates of 5-year CSS rates were 97.1%, 92.6%, 75.6%, and 42.7%, respectively.The 5-year OS rates for patients with luminal A, luminal B, HER2, and triple-negative subtypes of breast cancer were92.6%, 88.4%, 83.6%, and 82.9%, respectively, and the corresponding estimates of 5-year CSS rates were 93.2%, 89.1 %,85.4%, and 83.5%, respectively. Multivariate analysis showed that stage at diagnosis and molecular subtype were important prognostic factors for breast cancer.Conclusions: Survival of breast cancer patients varied significantly by stage and molecular subtype. Cancer screening is encouraged for the early detection and early diagnosis of breast cancer. More advanced therapies and health care policies are needed on HER2 and triple-negative subtypes.展开更多

The expression of estrogen receptor(ER), progesterone receptor(PR) and Ki67 among 525 neoadjuvant chemotherapy cases was studied by immunohistochemistry.Differences between specimens made through preoperative core needle biopsy and excised tissue biopsy were observed. The positive rates of ER, PR and Ki67 in core needle biopsy and excised tissue biopsy were 65.3% and 63.2%, 51.0% and 42.6%, 65.6% and 43.4%, respectively. The expression of ER, PR and Ki67 in core needle biopsy and excised tissue biopsy had no statistically significant difference. However, after neoadjuvant chemotherapy, the discordance rates of ER, PR and Ki67 were 15.2%(79/521), 26.9%(140/520) and 44.8%(225/502), respectively. The ER, PR and Ki67 status changed from positive to negative in 7.5%(39/521), 13.3%(69/520) and 21.1%(106/502) of the patients, whereas ER, PR and Ki67 status changed from negative to positive in 7.7%(40/521), 13.6%(71/520)and 23.7%(119/502) of the patients, respectively. These results showed that the status of some biomarkers changes after neoadjuvant chemotherapy and biomarker status needs to be reexamined to optimize adjuvant systemic therapy and better prognosis assessment.展开更多

Breast cancer diagnosis being a stressful experience, causes psychological and emotional disruption that can be abated by meeting information needs of the affected patients. In light of the escalating cases of Breast cancer among the Zambian women, the study examined a special aspect of cancer management which is usually neglected in most cases. Aim: The main objective of the study was to assess information needs of breast cancer patients at the Cancer Diseases Hospital in Lusaka, Zambia using a modified structured interview schedule adopted from the Toronto Information Needs Questionnaire-Breast Cancer (TINQ-BC). Methods: A descriptive cross-sectional design was used to elicit the information needs of breast cancer patients. One hundred and ten (97% response rate) participants were selected using simple random sampling method and data was collected using a modified structured interview schedule adopted from the Toronto Information Needs Questionnaire-Breast Cancer (TINQ-BC). Stata 10.0 (StataCorp, 2008) was employed for all quantitative data analysis and graphical presentation of data. Results: The overall score for information needs was obtained by adding the scores across all the five information needs categories which were further divided into three categories namely: low important scores, of less than 50%, moderately important scores of 50% - 70% and highly important scores ranged above 70% of the 200 total scores. Out of the 110 participants recruited, 88 (80%) indicated that the information across the five categories was moderately important. Logistic regression of information needs and posited determinants revealed that anxiety levels;education level;presence of co-morbidity;and being on treatment were significant determinants of patients’ informational needs (Effect’s p ≤ 0.05). Conclusion: The findings of this study support the idea that breast cancer patients are seeking more information on their illness, hence information provision is one of the most important factors for providing high quality cancer care across the whole cancer continuum. Therefore, appreciating the information needs of breast cancer patients is substantial in improving care.展开更多

CYP2D6*4 is one of the most frequent alleles associated with loss of enzymatic activity. The incidence of CYP2D6*4 among Caucasians is estimated up to 27%, while it is present in up to 90% of all poor metabolizers within the Caucasian population. The hypothesis under question is whether the presence of one or two non-functioning(null) alleles predicts an inferior outcome in postmenopausal women with breast cancer receiving adjuvant treatment with tamoxifen. The numerous existing studies investigating the association of CYP2D6 with treatment failure in breast cancer are inconsistent and give rather conflicting results. Currently, routine CYP2D6 testing among women with breast cancer is not recommended and the significance of CYP2D6 phenotype in decision making regarding the administration of tamoxifen is unclear.

AIM: To compare 2-deoxy-2-(^(18)F)fluoro-D-glucose(^(18)FFDG) and ^(18)F-sodium(^(18)F-NaF) positron emission tomography/computed tomography(PET/CT) accuracy in breast cancer patients with clinically/radiologically su...AIM: To compare 2-deoxy-2-(^(18)F)fluoro-D-glucose(^(18)FFDG) and ^(18)F-sodium(^(18)F-NaF) positron emission tomography/computed tomography(PET/CT) accuracy in breast cancer patients with clinically/radiologically suspected or known bone metastases.METHODS: A total of 45 consecutive patients with breast cancer and the presence or clinical/biochemical or radiological suspicion of bone metastatic disease underwent ^(18)F-FDG and ^(18)F-fluoride PET/CT. Imaging results were compared with histopathology when available, or clinical and radiological follow-up of at least 1 year. For each technique we calculated: Sensitivity(Se), specificity(Sp), overall accuracy, positive and negative predictive values, error rate, and Youden's index. Mc Nemar's χ~2 test was used to test the difference in sensitivity and specificity between the two diagnostic methods. All analyses were computed on a patient basis, and then on a lesion basis, with consideration ofthe density of independent lesions on the coregistered CT(sclerotic, lytic, mixed, no-lesions) and the divergent site of disease(skull, spine, ribs, extremities, pelvis). The impact of adding ^(18)F-Na F PET/CT to the work-up of patients was also measured in terms of change in their management due to ^(18)F-Na F PET/CT findings. RESULTS: The two imaging methods of ^(18)F-FDG and ^(18)F-fluoride PET/CT were significantly different at the patient-based analysis: Accuracy was 86.7% and 84.4%, respectively(Mc Nemar's χ~2 = 6.23, df = 1, P = 0.01). Overall, 244 bone lesions were detected in our analysis. The overall accuracy of the two methods was significantly different at lesion-based analysis(Mc Nemar's χ~2 = 93.4, df = 1, P < 0.0001). In the lesion density-based and site-based analysis, ^(18)F-FDG PET/CT provided more accurate results in the detection of CT-negative metastasis(P < 0.002) and vertebral localizations(P < 0.002); ^(18)F-Na F PET/CT was more accurate in detecting sclerotic(P < 0.005) and rib lesions(P < 0.04). ^(18)F-Na F PET/CT led to a change of management in 3 of the 45 patients(6.6%) by revealing findings that were not detected at ^(18)F-FDG PET/CT. CONCLUSION: ^(18)F-FDG PET/CT is a reliable imaging tool in the detection of bone metastasis in most cases, with a diagnostic accuracy that is slightly, but significantly, superior to that of ^(18)F-Na F PET/CT in the general population of breast cancer patients. However, the extremely high sensitivity of ^(18)F-fluoride PET/CT can exploit its diagnostic potential in specific clinical settings(i.e., small CT-evident sclerotic lesions, high clinical suspicious of relapse, and negative ^(18)F-FDG PET and conventional imaging).展开更多

文摘Introduction: Breast cancer is one of the leading causes of death worldwide. We carried out this study with the aim of evaluating the determinants of early survival of women with breast cancer in two hospitals in the city of Yaoundé. Methodology: This was an analytical cross-sectional study with retrospective and prospective data collection of breast cancer patients during 6 years in two Hospitals of Yaoundé from January 2017 to December 2022. We consulted the files in search of epidemiological, clinical, paraclinical, therapeutic and survival variables. We completed the survival data directly from the patients or their relatives after their consent. We analyzed the data using SPSS version 23.0 software. Survival analysis was done using the Kaplan-Meier method and survival curves were compared using the Log Rank test. Factors influencing survival were evaluated using the Cox model. The significance threshold (P value) was set at 0.05 at 95% confidence interval. The study was approved by the ethics committees. Results: We included 500 patients whose ages varied between 22 and 83 years with a mean age of 47.19 ± 11.61 years. The most represented age group was 30 to 45 years old (45.8%). Less than half (41.6%) were postmenopausal. The most frequent reason for consultation was a breast lump (79.9%). The most common clinical stage at presentation was stage-3 (47.6%). Infiltrating ductal carcinoma was the most represented histological type (84.7%). The most represented histological grade was grade 2 (40.2%). Immunohistochemistry was performed in 34.20% of cases. The most represented molecular subtype was triple negative (41.8%) followed by Luminal A (30%). Concerning treatment, 17.2% did not receive any, 45% had surgery, 79.4% had chemotherapy, 34.2% hormone therapy, and 14.6% radiotherapy. The survival of patients with breast cancer at 1, 2, 3, 4 and 5 years was respectively 90.6%;83.1%;74.2%;69.8% and 59.2%. The median survival was not reached;however, the first quartile (Q1) was 36 months (3 years). Independent factors associated with reduced survival were breast ulceration (aHR = 3.23;p = 0.002), bilateral tumor location (aHR = 9.2;p < 0.001) and clinical stage 3 (aHR = 1.72;p = 0.010) while patients classified ACR3 on imaging (aHR = 0.19;p = 0.005) had improved survival. Conclusion: Breast cancer survival from 1 to 5 years decrease from 90 to 59%. Mortality was highest in the first 40 months. Independent factors associated with reduced survival were breast ulceration, bilateral tumor location and clinical stage 3 while patients classified ACR3 on imaging had improved survival.

文摘Breast cancer is the predominant form of carcinoma among women worldwide,with 70%of advanced patients developing bone metastases,with a high mortality rate.In this sense,the bone marrow(BM)mesenchymal stem/stromal cells(MSCs)are critical for BM/bone homeostasis,and failures in their functionality,transform the BM into a premetastatic niche(PMN).We previously found that BM-MSCs from advanced breast cancer patients(BCPs,infiltrative ductal carcinoma,stage III-B)have an abnormal profile.This work aims to study some of the metabolic and molecular mechanisms underlying MSCs shift from a normal to an abnormal profile in this group of patients.A comparative analysis was undertaken,which included self-renewal capacity,morphology,proliferation capacity,cell cycle,reactive oxygen species(ROS)levels,and senescence-associatedβ‑galactosidase(SA‑β‑gal)staining of BMderived MSCs isolated from 14 BCPs and 9 healthy volunteers(HVs).Additionally,the expression and activity of the telomerase subunit TERT,as well as telomere length,were measured.Expression levels of pluripotency,osteogenic,and osteoclastogenic genes(OCT-4,SOX-2,M-CAM,RUNX-2,BMP-2,CCL-2,M-CSF,and IL-6)were also determined.The results showed that MSCs from BCPs had reduced,self-renewal and proliferation capacity.These cells also exhibited inhibited cell cycle progression and phenotypic changes,such as an enlarged and flattened appearance.Additionally,there was an increase in ROS and senescence levels and a decrease in the functional capacity of TERT to preserve telomere length.We also found an increase in pro-inflammatory/pro-osteoclastogenic gene expression and a decrease in pluripotency gene expression.We conclude that these changes could be responsible for the abnormal functional profile that MSCs show in this group of patients.
文摘BACKGROUND Breast cancer in young women has been shown to have an aggressive behavior and poor prognosis.AIM To evaluate the outcomes of young hormone receptor(HR)-positive patients with breast cancer treated with neoadjuvant chemotherapy(NAC),and the oncologic efficacy of gonadotropin-releasing hormone(GnRH)agonists.METHODS This retrospective study involved a prospectively enrolled cohort.We included patients diagnosed with invasive breast cancer who were treated with NAC followed by curative surgery at the Samsung Medical Center and Samsung Changwon Hospital between January 2006 and December 2017.Among patients with HR-positive and human epidermal grow factor 2(HER2)-negative breast cancer,we analyzed the characteristics and oncology outcomes between the patients equal to or younger than 35 years and the patients older than 35 years.RESULTS Among 431 patients with NAC and HR-positive/HER2-negative breast cancer,78 were 35 years old or younger,and 353 patients were older than 35 years.The median follow-up was 71.0 months.There was no statistically significant difference in disease free survival(DFS,P=0.565)and overall survival(P=0.820)between the patients equal to or younger than 35 years and the patients older than 35 years.The two groups differed in that the GnRH agonist was used more frequently in the group of patients equal to or younger than 35 years than in the other group(52.4%vs 11.2%,P<0.001).Interestingly,for the DFS according to the GnRH agonist in the group of patients equal to or younger than 35 years,patients treated with the GnRH agonist had better DFS(P=0.037).CONCLUSION Administration of GnRH agonists might improve the DFS rate of HR-positive/HER2-negative breast cancer in the equal to or younger than 35 years group of patients with NAC.

文摘Objective:The purpose of this study was to evaluate the effectiveness of post-traumatic growth(PTG)model-based intervention to improve positive psychological traits in Chinese breast cancer patients.Design:A randomized control trial of a psychological group intervention based on PTG model.Methods:The Clinical Trial was registered on 17 August 2019 at Chinese Clinical Trials.gov with Registration number ChiCTR1900025264.A total of 92 patients with breast cancer were recruited.The participants were randomly assigned to the experimental group(n=46)and the control group(n=46).A six-session psychological group intervention based on PTG model was implemented in the experimental group,and a six-session health education was implemented in the control group.The outcomes weremeasured at baseline(pre-intervention),3 weeks,6 weeks after the intervention.The primary outcome was posttraumatic growth assessed by the Chinese version of the Post-Traumatic Growth Inventory(PTGI);Secondary outcomes included psychological resilience,family resilience,rumination,and self-disclosure.Results:A total of 87 patients with breast cancer completed this study,including 44 patients in the experimental group and 43 patients in the control group.There was no significant difference in baseline data of breast cancer patients between the two groups except for the treatment regimen(p>0.05).The two groups were compared after the intervention;the interaction effects between the total scores of posttraumatic growth,family resilience,and self-disclosure and the time term were statistically significant(p<0.05),indicating that the trend of change in total scores of post-traumatic growth,family resilience,and self-disclosure differed between the experimental and control groups over time,and the scores improved in the experimental group were significantly higher than those in the control group.The comparison of psychological resilience and total score of rumination at each time point was statistically significant(p<0.05),indicating that group intervention based on the PTG model could improve the psychological recovery ability and rumination level of the experimental group.Conclusion:The psychological group intervention based on the PTG model significantly improved post-traumatic growth,family resilience,and self-disclosure in patients with breast cancer.However,the impact on psychological resilience and rumination was relatively small.Long-term intervention is needed to further test the effect of the PTG model on psychological resilience and rumination.
文摘Introduction: Breast cancer is the number one malignancy affecting females in Saudi Arabia with a prevalence of 22.4%. Breast cancer incidence increases annually due to the aid of established screening programs, leading to the discovery of breast cancer in its early stages. Surgical treatment is an integral part of early breast cancer management to achieve local control. Axillary surgical interventions such sentinel lymph node biopsy (SLNB) and axillary lymph node clearance (ALND) aim to stage the axilla as an adjunct to the management of the primary breast tumor. In this paper, we reviewed female breast cancer patients aged 30 - 60 who underwent surgical treatment of SLNB and/or ALND with reporting the prevalence of lymphedema and other associated complications and risk factors. Methodology: A cross-sectional non-interventional study, with a sample size of 250 including breast cancer cases from 2016 to 2019 at National Guard Hospital (NGH) in Jeddah, Saudi Arabia. Results: A total of 253 breast cancer cases were included in this study, with a mean age of 53 years, 52.7% were postmenopausal and positive family history was present among 21% of cases. Further, 90.9% of the cases had unilateral disease. Staging was as follows: stage I 14.5%, stage II 45.2%, stage III 37.1%, and stage IV 3.2%. Mastectomy was done in 73.4% cases and lumpectomy was performed in 34.1% of cases. In addition, 93.3% of patients had SLNB and 49% of them were positive. Axillary dissection was performed in 69.6% of our patients. Radiotherapy and chemotherapy were given to 71.8% and 80.4% of cases respectively. Among the chemotherapy (chemo) recipients, 40.2% received adjuvant chemo, 54.5% received neoadjuvant chemo, and the remaining 5.3% received both. Further, the most prevalent complication was pain accounting for 42.1% of total complications, and the least prevalent was cellulitis 4%. Also, seroma developed in 18.3% cases, paresthesia noted in 5.6% of cases, winged scapula was reported as 2%, weakness and necrosis were seen in 6% and 13.1% of cases respectively. Axillary vein thrombosis and lymphangiosarcoma were reported in none of the patients (0%). Lymphoedema accounted for 16.1% of overall complications, 85% of the patients who developed lymphedema had undergone ALND, and 12.9% and 14.4% received radiotherapy and chemotherapy respectively. Lymphedema was observed in breast cancer stages as follows: stage I 1.2%, stage II 7.2%, and stage III 5.2%. Patients with body mass index (BMI) of 30 - 39 kg/m<sup>2</sup> had 7.2% prevalence of lymphedema compared to other BMI groups. Overall mortality was 8.3%. Conclusion: The findings of our study suggest that the prevalence of lymphedema was higher in ALND patients with locally advanced tumors, and higher BMI, compared to patients with stage I breast cancer and low BMI. Further, the prevalence of lymphedema in patients who underwent ALND was significantly lower than those who were treated by lumpectomy 10.3% (p-value = 0.034) in comparison to mastectomy 19.3%.

文摘Background: Stage at diagnosis and molecular subtype are important clinical factors associated with breast cancer patient survival. However, subgroup survival data from a large study sample are limited in China.To estimate the survival differences among patients with different stages and various subtypes of breast cancer, we conducted a hospital-based multi-center study on breast cancer in Beijing, China.Methods: All resident patients diagnosed with primary, invasive breast cancer between January 1,2006 and December 31,2010 from four selected hospitals in Beijing were included and followed up until December 31,2015. Hospitalbased data of stage at diagnosis, hormone receptor status, and selected clinical characteristics, including body mass index(BMI), menopausal status, histological grade, and histological type, were collected from the medical records of the study subjects. Overall survival(OS) and cancer-specific survival(CSS) were estimated. Cox proportional hazards models were employed to evaluate the associations of stage at diagnosis and molecular subtype with patient survival.Results: The 5-year OS and CSS rates for all patients were 89.4% and 90.3%. Survival varied by stage and molecular subtype. The 5-year OS rates for patients with stage I, Ⅱ, Ⅲ, and IV diseases were 96.5%, 91.6%, 74.8%, and 40.7%,respectively, and the corresponding estimates of 5-year CSS rates were 97.1%, 92.6%, 75.6%, and 42.7%, respectively.The 5-year OS rates for patients with luminal A, luminal B, HER2, and triple-negative subtypes of breast cancer were92.6%, 88.4%, 83.6%, and 82.9%, respectively, and the corresponding estimates of 5-year CSS rates were 93.2%, 89.1 %,85.4%, and 83.5%, respectively. Multivariate analysis showed that stage at diagnosis and molecular subtype were important prognostic factors for breast cancer.Conclusions: Survival of breast cancer patients varied significantly by stage and molecular subtype. Cancer screening is encouraged for the early detection and early diagnosis of breast cancer. More advanced therapies and health care policies are needed on HER2 and triple-negative subtypes.

文摘This study was designed to investigate the effect of neoadjuvant chemotherapy on the expression of hormone receptors and Ki67 in Chinese female breast cancer patients. The expression of estrogen receptor(ER), progesterone receptor(PR) and Ki67 among 525 neoadjuvant chemotherapy cases was studied by immunohistochemistry.Differences between specimens made through preoperative core needle biopsy and excised tissue biopsy were observed. The positive rates of ER, PR and Ki67 in core needle biopsy and excised tissue biopsy were 65.3% and 63.2%, 51.0% and 42.6%, 65.6% and 43.4%, respectively. The expression of ER, PR and Ki67 in core needle biopsy and excised tissue biopsy had no statistically significant difference. However, after neoadjuvant chemotherapy, the discordance rates of ER, PR and Ki67 were 15.2%(79/521), 26.9%(140/520) and 44.8%(225/502), respectively. The ER, PR and Ki67 status changed from positive to negative in 7.5%(39/521), 13.3%(69/520) and 21.1%(106/502) of the patients, whereas ER, PR and Ki67 status changed from negative to positive in 7.7%(40/521), 13.6%(71/520)and 23.7%(119/502) of the patients, respectively. These results showed that the status of some biomarkers changes after neoadjuvant chemotherapy and biomarker status needs to be reexamined to optimize adjuvant systemic therapy and better prognosis assessment.
文摘Human epidermal growth factor receptor 2(HER2)-overexpressing breast cancer is an aggressive phenotype with a poor prognosis,and can easily metastasize and recur.Currently,chemotherapy plus HER2-targeted therapy is the standard systemic treatment for most of these patients.Given that neoadjuvant chemotherapy(NAC)has an efficacy equivalent to that of adjuvant chemotherapy and some additional benefits,many patients,especially those with more advanced tumors,prefer NAC and generally will not receive additional chemotherapy after surgery,irrespective of the pathological response.However,achieving pathological complete response to NAC is strongly correlated with prognosis,especially in triple-negative and HER2-overexpressing breast cancer.Therefore,postoperative treatment of these patients with residual diseases should be optimized to achieve favorable outcomes.The CREATE-X study has confirmed that additional chemotherapy can improve the outcomes of patients with HER2-negative residual disease after NAC.In addition,chemotherapy plays an indispensable role in the treatment of patients who receive surgery directly or who have recurrent lesions.Therefore,can additional chemotherapy improve prognosis of patients with HER2-overexpressing residual breast cancer?At present,no studies have compared the efficacy of additional chemotherapy plus trastuzumab with that of anti-HER2 therapy alone in residual cancer.The KATHERINE study revealed that trastuzumab emtansine(T-DM1)can reduce the risk of recurrence or death by 50%compared with trastuzumab in patients with HER2-positive residual invasive breast cancer after neoadjuvant therapy.T-DM1 is an antibody-drug conjugate of trastuzumab and the cytotoxic agent emtansine,and thus,to an extent,T-DM1 is equivalent to simultaneous application of chemotherapy and targeted therapy.However,high cost and low accessibility limit its use especially in low-and middle-income countries and regions.Hence,we proposed this perspective that additional chemotherapy plus trastuzumab should be given to HER2-overexpressing breast cancer patients with residual disease after NAC to improve their prognosis by discussing that the efficacy of additional chemotherapy plus trastuzumab is superior to that of anti-HER2 therapy alone and not inferior to T-DM1.Additional chemotherapy plus trastuzumab-based HER2-targeted therapy can be used as an alternative regimen to T-DM1 when T-DM1 is unavailable.However,further clinical research on the selection of chemotherapeutic agents is warranted.
文摘Background: Breast cancer is the second most common cancer worldwide and the second most common among Zambian women. Breast cancer diagnosis being a stressful experience, causes psychological and emotional disruption that can be abated by meeting information needs of the affected patients. In light of the escalating cases of Breast cancer among the Zambian women, the study examined a special aspect of cancer management which is usually neglected in most cases. Aim: The main objective of the study was to assess information needs of breast cancer patients at the Cancer Diseases Hospital in Lusaka, Zambia using a modified structured interview schedule adopted from the Toronto Information Needs Questionnaire-Breast Cancer (TINQ-BC). Methods: A descriptive cross-sectional design was used to elicit the information needs of breast cancer patients. One hundred and ten (97% response rate) participants were selected using simple random sampling method and data was collected using a modified structured interview schedule adopted from the Toronto Information Needs Questionnaire-Breast Cancer (TINQ-BC). Stata 10.0 (StataCorp, 2008) was employed for all quantitative data analysis and graphical presentation of data. Results: The overall score for information needs was obtained by adding the scores across all the five information needs categories which were further divided into three categories namely: low important scores, of less than 50%, moderately important scores of 50% - 70% and highly important scores ranged above 70% of the 200 total scores. Out of the 110 participants recruited, 88 (80%) indicated that the information across the five categories was moderately important. Logistic regression of information needs and posited determinants revealed that anxiety levels;education level;presence of co-morbidity;and being on treatment were significant determinants of patients’ informational needs (Effect’s p ≤ 0.05). Conclusion: The findings of this study support the idea that breast cancer patients are seeking more information on their illness, hence information provision is one of the most important factors for providing high quality cancer care across the whole cancer continuum. Therefore, appreciating the information needs of breast cancer patients is substantial in improving care.
文摘Biotransformation of tamoxifen to the potent antiestrogen endoxifen is performed by cytochrome P450(CYP) enzymes, in particular the CYP2D6 isoform. CYP2D6*4 is one of the most frequent alleles associated with loss of enzymatic activity. The incidence of CYP2D6*4 among Caucasians is estimated up to 27%, while it is present in up to 90% of all poor metabolizers within the Caucasian population. The hypothesis under question is whether the presence of one or two non-functioning(null) alleles predicts an inferior outcome in postmenopausal women with breast cancer receiving adjuvant treatment with tamoxifen. The numerous existing studies investigating the association of CYP2D6 with treatment failure in breast cancer are inconsistent and give rather conflicting results. Currently, routine CYP2D6 testing among women with breast cancer is not recommended and the significance of CYP2D6 phenotype in decision making regarding the administration of tamoxifen is unclear. The present study summarizes current literature regarding clinical studies on CYP2D6*4, par-ticularly in terms of response to tamoxifen therapy and breast cancer outcome.
文摘Objective:Family caregivers(FCs)of breast cancer patients play a vital role throughout the treatment process.Psychological distress of FCs is common and often ignored.A simple and effective instrument for screening psychological distress would help in selecting those FCs requiring special attention and intervention.Here,the validity of distress thermometer(DT)in FCs of Chinese breast cancer patients receiving postoperative chemotherapy was assessed,and the prevalence of anxiety and depression was evaluated.Methods:We recruited 200 FCs of hospitalized breast cancer patients in this cross-sectional descriptive study.Before the first cycle of adjuvant chemotherapy,the levels of anxiety and depression among FCs were assessed using DT and Hospital Anxiety and Depression Scale(HADS).In total,191 valid cases were analyzed.HADS was used as the diagnostic standard to assess the effectiveness of DT as a screening tool for anxiety and depression as well as to analyze the diagnostic efficiency of DT at various cutoff points.Results:The definitive prevalence of both anxiety and depression was 8.90%.The mean level of anxiety and depression among FCs was 5.64±3.69 and 5.09±3.85,respectively,both of which were significantly higher than corresponding Chinese norms(P<0.01).The areas under receiver operating characteristic curves of DT for the diagnoses of FCs'anxiety and depression were 0.904 and 0.885,respectively.A cutoff value of 5 produced the best diagnostic effects of DT for anxiety and depression.Conclusions:The levels of both anxiety and depression were higher in the FCs of Chinese breast cancer patients receiving postoperative chemotherapy than the national norm.DT might be an effective tool to initially screen psychological distress among FCs.This process could be integrated into the palliative care of breast cancer patients and warrant further research.
文摘Objective The aim of this study was to compare the efficacy and safety of pegylated recombinant human granulocyte colony-stimulating factor(PEG-rhG-CSF)and recombinant human granulocyte colonystimulating factor(rhG-CSF)for the prevention of neutropenia in elderly breast cancer patients during adjuvant chemotherapy.Methods A total of 45 oncology inpatients with breast cancer,who received adjuvant chemotherapy and were older than 65 years from May 2017 to October 2018 in the General Hospital of the Northern Theater of the Chinese people’s Liberation Army,were included.Epirubivin Cyclophoshamide-Docetaxel(EC-T)sequential adjuvant chemotherapy was chosen.Forty-five patients were randomly divided into two groups;25 patients in the treatment group were treated with PEG-rhG-CSF and 20 patients in the control group were not treated with PEG-rhG-CSF,but only rhG-CSF.The experimental group was treated with the PEG-rhG-CSF at the end of chemotherapy for 24–48 h,with a 6 mg subcutaneous injection once per chemotherapy cycle.In the control group,rhG-CSF was administered after 48 h of chemotherapy,with a 100μg subcutaneous injection,1/d,d 1–7.The dosage could be increased step by step with the exacerbation of neutropenia.The primary aims of this study was to discover the incidence of leukopenia,neutropenia,neutrophilic fever,and adverse reactions in the two groups.Results The incidence of neutropenia,neutrophilic fever and adverse reactions decreased in the treatment group compared to the control group,but no significant difference existed between two groups(P>0.05).Patients in treatment group had a lower,but not statistically significant,incidence of adverse reactions(P>0.05).Conclusion Applying PEG-rhG-CSF could be effective in preventing neutropenia in elderly patients with postoperative adjuvant chemotherapy to treat breast cancer.It may effectively control the occurrence of neutropenia after chemotherapy and reduce the chance of infection.The incidence of side effects,such as fever and bone pain,was low.The adverse drug reactions were well tolerated by patients,which could ensure the smooth progress of chemotherapy.

文摘Epigenetic modifications have been observed as a decline in miRNA-21 expression and breast cancer stem cell(CSC)population after 3 cycles of standard chemotherapy.The epigenetic response(miRNAs expression)and CSCs are also correlated in patients with Breast Cancer.In patients who tolerated chemotherapy well,miRNA-21(non-coding RNA)expression decreased significantly after three cycles of chemotherapy.The miRNA-21 expression in breast cancer tissue was quantified by quantitative PCR(real-time PCR)using the standard protocol.In addition,breast CSCs(CD44+/CD24-)were also decreased in these patients.The miRNA-21 regulates cell division,proliferation,and autophagy of cancerous cells(as it targets phosphatase and tensin homolog/AKT/transcription factor EB/programmed cell death 4/autophagy-related protein 5 and chemotherapy also produces similar effects),thereby contributing to these benefits.Therefore,when all of the targets on genes have been explored by mimic miRNA,chemotherapy combined with anti-miRNA21 therapy may prove useful in the care of cancer patients.
文摘AIM: To compare 2-deoxy-2-(^(18)F)fluoro-D-glucose(^(18)FFDG) and ^(18)F-sodium(^(18)F-NaF) positron emission tomography/computed tomography(PET/CT) accuracy in breast cancer patients with clinically/radiologically suspected or known bone metastases.METHODS: A total of 45 consecutive patients with breast cancer and the presence or clinical/biochemical or radiological suspicion of bone metastatic disease underwent ^(18)F-FDG and ^(18)F-fluoride PET/CT. Imaging results were compared with histopathology when available, or clinical and radiological follow-up of at least 1 year. For each technique we calculated: Sensitivity(Se), specificity(Sp), overall accuracy, positive and negative predictive values, error rate, and Youden's index. Mc Nemar's χ~2 test was used to test the difference in sensitivity and specificity between the two diagnostic methods. All analyses were computed on a patient basis, and then on a lesion basis, with consideration ofthe density of independent lesions on the coregistered CT(sclerotic, lytic, mixed, no-lesions) and the divergent site of disease(skull, spine, ribs, extremities, pelvis). The impact of adding ^(18)F-Na F PET/CT to the work-up of patients was also measured in terms of change in their management due to ^(18)F-Na F PET/CT findings. RESULTS: The two imaging methods of ^(18)F-FDG and ^(18)F-fluoride PET/CT were significantly different at the patient-based analysis: Accuracy was 86.7% and 84.4%, respectively(Mc Nemar's χ~2 = 6.23, df = 1, P = 0.01). Overall, 244 bone lesions were detected in our analysis. The overall accuracy of the two methods was significantly different at lesion-based analysis(Mc Nemar's χ~2 = 93.4, df = 1, P < 0.0001). In the lesion density-based and site-based analysis, ^(18)F-FDG PET/CT provided more accurate results in the detection of CT-negative metastasis(P < 0.002) and vertebral localizations(P < 0.002); ^(18)F-Na F PET/CT was more accurate in detecting sclerotic(P < 0.005) and rib lesions(P < 0.04). ^(18)F-Na F PET/CT led to a change of management in 3 of the 45 patients(6.6%) by revealing findings that were not detected at ^(18)F-FDG PET/CT. CONCLUSION: ^(18)F-FDG PET/CT is a reliable imaging tool in the detection of bone metastasis in most cases, with a diagnostic accuracy that is slightly, but significantly, superior to that of ^(18)F-Na F PET/CT in the general population of breast cancer patients. However, the extremely high sensitivity of ^(18)F-fluoride PET/CT can exploit its diagnostic potential in specific clinical settings(i.e., small CT-evident sclerotic lesions, high clinical suspicious of relapse, and negative ^(18)F-FDG PET and conventional imaging).
文摘BACKGROUND Pegylated liposomal doxorubicin(PLD)uses the hydrophilic layer of liposomes to reach the sweat on the skin surface or accumulate in the sweat glands,producing toxic free radicals and oxidative damage,resulting in hand-foot syndrome(HFS).Regional cooling can induce vasoconstriction to reduce the release of drugs in the limbs and reduce the accumulation of drugs in sweat glands;thus,decreasing the incidence and severity of HFS.AIM To study the efficacy of cooling patches to prevent HFS caused by PLD in the short-term.METHODS This is a retrospective cohort study.Female breast cancer patients(n=101)who were treated with PLD in two breast wards at our department from February 2020 to February 2021 were enrolled in the study and were randomly divided into the cooling group(51 patients)and the control group(50 patients).Patients in the control group only received routine care,while the patients in the cooling group applied cooling patches,based on routine care,to the palm and back of the hands 15 min before chemotherapy infusion for 10 h.All patients took a corresponding dose of dexamethasone orally one day before chemotherapy,on the day of chemotherapy,and one day after chemotherapy.SPSS23.0 version was used to analyze the data in this study.The occurrence and severity of HFS was analyzed by the Mann-Whitney U test,and scores were analyzed by the Student’s t test or Wilcoxon rank-sum test.A P value<0.05 was regarded as statistically significant.RESULTS In this study,neither group of patients developed Grade 3 HFS.In the control group,the incidence of Grade 1 HFS and Grade 2 HFS was 38%and 2%,respectively.However,in the cooling group,only one person developed Grade 1 HFS(2%),and none of the patients developed Grade 2 HFS.These findings showed that cooling patches can effectively reduce the frequency and severity of HFS(P<0.0001)in the short-term.Before the fourth chemotherapy cycle,although general self-efficacy scale scores in the cooling group were low,they were still significantly higher than those in the control group(17.22±5.16 vs 19.63±6.42,P=0.041).Compared with the control group,the mean Hand-Foot Skin Reaction and Quality of Life Questionnaire score in the cooling group was significantly lower(18.08±7.01 vs 14.20±7.39,P=0.008).CONCLUSION Cooling patches can effectively reduce the frequency and severity of HFS caused by PLD in the short-term.In addition,it may help delay the decline in patients’self-efficacy.
