Methods: A total of 60 tumor patients receiving oxaliplatin for 1 - 6 cycles of chemotherapy from January to September 2023 were selected. 30 patients were selected from January to March and divided into the control group, and 30 patients were selected from July to 9 as the experimental group. The control group received conventional chemotherapy nursing, while the experimental group received integrated nursing. Anxiety, peripheral nerve toxicity stage and quality of life score were compared between the two groups before and after intervention. Results: After intervention, the scores of the self-rating Anxiety Scale (SAS) and the total scores of the oxaliplatin Levi specific sensory neurotoxicity scale in the experimental group were significantly lower than those in the control group, and the differences were statistically significant (P< 0.05);The Quality of Life Scale (FACT-G) score of cancer patients was higher than that of control group, and the difference was statistically significant (P< 0.05). Conclusion: The integrated nursing model can effectively reduce the anxiety of patients, reduce the incidence of peripheral nerve injury and improve the quality of life of patients.展开更多

The main objective of this study is to find out the possible existence of this type of links. Method: This is a systematic literature review that seeks to find out which and how long cases of late interactions related to chemotherapy and radiotherapy treatments have been known. The bibliographic review was carried out based on references published in the last five years. Results: Various studies confirm the possible relationship between chemotherapy and radiotherapy treatments with the development of new undesirable side effects, especially as a consequence of the hepatotoxicity generated in the case of chemotherapy and radiation in radiotherapy. However, in this last type of treatment, the problems raised are really few. Conclusions: The existence of a risk of suffering new unwanted side effects after different types of treatment seems to have been demonstrated, especially in the case of chemotherapy. In the case of radiotherapy, adverse effects are practically non-existent, although they are no less important.展开更多

The age of onset of gastric cancer is in line with the general rule of cancer. Most of them occur after middle age, mostly between 40and 60 years old, with an average age of about 50 years old, and only 5% of patients are under 30 years old. The incidence of male is higher than that of female.AIM To investigate the short-term efficacy and influencing factors of chemotherapy combined with irinotecan in patients with advanced gastric cancer.METHODS Eighty patients with advanced gastric cancer who were treated in our hospital from January 2019 to January 2022 were selected. The patients were divided into an observation group(n = 40) and control group(n = 40) by the envelope method.The control group was given preoperative routine chemotherapy. The observation group was treated with irinotecan in addition to the chemotherapy given to the control group. The short-term efficacy of treatment in the two groups, as well as tumor marker levels and quality of life before and after treatment were evaluated.RESULTS The short-term treatment effect in the observation group was better than that in the control group(P < 0.05), and the total effective rate was 57.50%. The age and proportion of tumor node metastasis(TNM) stage IV patients with ineffective chemotherapy in the observation group were(65.12 ± 5.71) years and 52.94%,respectively, which were notably higher than those of patients with effective chemotherapy(P < 0.05), while the Karnofsky Performance Scale score was(67.70± 3.83) points, which was apparently lower than that of patients with effective chemotherapy(P <0.05). After 3 mo of treatment, the SF-36 scale scores of physiological function, energy, emotional function, and mental health in the observation group were 65.12 ± 8.14, 54.76 ± 6.70, 47.58 ± 7.22,and 66.16 ± 8.11 points, respectively, which were considerably higher than those in the control group(P < 0.05). The incidence rates of grade Ⅲ-Ⅳ diarrhea and grade Ⅲ-Ⅳ thrombocytopenia in the observation group were 32.50% and 25.00%, respectively, which were markedly higher than those in the control group(P < 0.05).CONCLUSION Chemotherapy combined with irinotecan in patients with advanced gastric cancer has a good short-term efficacy and can significantly reduce serum tumor markers and improve the quality of life of patients. The efficacy may be affected by the age and TNM stage of the patients, and its long-term efficacy needs further study.展开更多
文摘BACKGROUND Neoadjuvant therapy is an essential modality for reducing the clinical stage of esophageal cancer;however,the superiority of neoadjuvant chemotherapy(nCT)or neoadjuvant chemoradiotherapy(nCRT)is unclear.Therefore,a discussion of these two modalities is necessary.AIM To investigate the benefits and complications of neoadjuvant modalities.METHODS To address this concern,predefined criteria were established using the PICO protocol.Two independent authors performed comprehensive searches using predetermined keywords.Statistical analyses were performed to identify significant differences between groups.Potential publication bias was visualized using funnel plots.The quality of the data was evaluated using the Risk of Bias Tool 2(RoB2)and the GRADE approach.RESULTS Ten articles,including 1928 patients,were included for the analysis.Significant difference was detected in pathological complete response(pCR)[P<0.001;odds ratio(OR):0.27;95%CI:0.16-0.46],30-d mortality(P=0.015;OR:0.4;95%CI:0.22-0.71)favoring the nCRT,and renal failure(P=0.039;OR:1.04;95%CI:0.66-1.64)favoring the nCT.No significant differences were observed in terms of survival,local or distal recurrence,or other clinical or surgical complications.The result of RoB2 was moderate,and that of the GRADE approach was low or very low in almost all cases.CONCLUSION Although nCRT may have a higher pCR rate,it does not translate to greater long-term survival.Moreover,nCRT is associated with higher 30-d mortality,although the specific cause for postoperative complications could not be identified.In the case of nCT,toxic side effects are suspected,which can reduce the quality of life.Given the quality of available studies,further randomized trials are required.

文摘BACKGROUND Advanced pancreatic cancer is resistant to chemotherapeutic drugs,resulting in limited treatment efficacy and poor prognosis.Combined administration of the chemotherapeutic gemcitabine and erlotinib is considered a potential first-line treatment for advanced pancreatic cancer.However,their comparative benefits and potential risks remain unclear.AIM To assess the clinical efficacy and safety of erlotinib combined with other chemotherapy regimens for the treatment of advanced pancreatic cancer.METHODS Literature on the clinical efficacy and safety of erlotinib combined with chemotherapy for advanced pancreatic cancer was retrieved through an online search.The retrieved literature was subjected to a methodological qualitative assessment and was analyzed using the RevMan 5.3 software.Ten randomized controlled trials involving 2444 patients with advanced pancreatic cancer were included in the meta-analysis.RESULTS Compared with chemotherapeutic treatment,erlotinib combined with chemotherapy significantly prolonged the progression-free survival time of pancreatic cancer patients[hazard ratio(HR)=0.78,95%CI:0.66-0.92,P=0.003].Meanwhile,the overall survival(HR=0.99,95%CI:0.72-1.37,and P=0.95)and disease control rate(OR=0.93,95%CI:0.45-0.91,P=0.84)were not significantly favorable.In terms of safety,the erlotinib and chemotherapy combination was associated with a significantly higher risk of diarrhea(OR=3.59,95%CI:1.63-7.90,P<0.05)and rash(OR=3.63,95%CI:1.64-8.01,P<0.05)compared with single-agent chemotherapy.Moreover,the risk of vomiting(OR=1.27,95%CI:0.62-2.59,P=0.51),regurgitation/anorexia(OR=1.61,95%CI:0.25-10.31,P=0.62),and infection(OR=0.72,95%CI:0.28-1.87,P=0.50)were not significant in either group.CONCLUSION Compared with a single chemotherapeutic modality,erlotinib combined with gemcitabine can prolong progression-free survival in pancreatic cancer,but does not improve survival benefit or disease control rate,and can increase the risk of diarrhea and rash.
文摘Objective: To investigate the effect of the integrated nursing model in the prevention of chemotherapy-induced peripheral injury. Methods: A total of 60 tumor patients receiving oxaliplatin for 1 - 6 cycles of chemotherapy from January to September 2023 were selected. 30 patients were selected from January to March and divided into the control group, and 30 patients were selected from July to 9 as the experimental group. The control group received conventional chemotherapy nursing, while the experimental group received integrated nursing. Anxiety, peripheral nerve toxicity stage and quality of life score were compared between the two groups before and after intervention. Results: After intervention, the scores of the self-rating Anxiety Scale (SAS) and the total scores of the oxaliplatin Levi specific sensory neurotoxicity scale in the experimental group were significantly lower than those in the control group, and the differences were statistically significant (P< 0.05);The Quality of Life Scale (FACT-G) score of cancer patients was higher than that of control group, and the difference was statistically significant (P< 0.05). Conclusion: The integrated nursing model can effectively reduce the anxiety of patients, reduce the incidence of peripheral nerve injury and improve the quality of life of patients.

文摘Objective Anthracycline-containing regimens are irreplaceable in neoadjuvant chemotherapy(NAC)for breast cancer(BC)at present.However,30% of early breast cancer(EBC)patients are resistant to anthracycline-containing chemotherapy,leading to poor prognosis and higher mortality.Ki-67 is associated with the prognosis and response to therapy,and it changes after NAC.Methods A total of 105 BC patients who received anthracycline-containing NAC were enrolled.Then,the optimal model of Ki-67 was selected,and its predictive efficacy was analyzed.Immunohistochemistry(IHC)was used to determine the estrogen receptor(ER),progesterone receptor(PR),and human epidermal growth factor receptor 2(HER-2)status and Ki-67 level.Fluorescent in situ hybridization(FISH)was used to verify the HER-2 when the IHC score was 2+.Results The post-NAC Ki67 level after treatment with anthracycline drugs was lower than pre-NAC Ki-67(19.6%±23.3%vs.45.6%±23.1%,P<0.001).Furthermore,patients with the Ki-67 decrease had a border line higher pathological complete response(pCR)rate(17.2%vs.0.0%,P=0.068),and a higher overall response rate(ORR)(73.6%vs.27.8%,P<0.001),when compared to patients without the Ki-67 decrease.The ΔKi-67 and ΔKi-67%were valuable markers for the prediction of both the pCR rate and ORR.The area under the curve(AUC)for ΔKi-67 on pCR and ORR was 0.809(0.698-0.921)and 0.755(0.655-0.855),respectively,while the AUC for ΔKi-67% on pCR and ORR was 0.857(0.742-0.972)and 0.720(0.618-0.822),respectively.Multivariate logistic regression model 1 revealed thatΔKi-67 was an independent predictor for both pCR[odds ratio(OR)=61.030,95% confidence interval(CI)=4.709-790.965;P=0.002]and ORR(OR=10.001,95%CI:3.044-32.858;P<0.001).Multivariate logistic regression model 2 revealed thatΔKi-67%was also an independent predictor for both pCR(OR=408.922,95%CI=8.908-18771.224;P=0.002)and ORR(OR=5.419,95%CI=1.842-15.943;P=0.002).Conclusions The present study results suggest thatΔKi67 andΔKi67%are candidate predictors for anthracycline-containing NAC response,and that they may provide various information for further systematic therapy after surgery in clinical practice.

文摘BACKGROUND The efficacy of neoadjuvant chemotherapy(NAC)in advanced gastric cancer(GC)is still a controversial issue.AIM To find factors associated with chemosensitivity to NAC treatment and to provide the optimal therapeutic strategies for GC patients receiving NAC.METHODS The clinical information was collected from 230 GC patients who received NAC treatment at the Central South University Xiangya School of Medicine Affiliated Haikou Hospital from January 2016 to December 2020.Least absolute shrinkage and selection operator logistic regression analysis was used to find the possible predictors.A nomogram model was employed to predict the response to NAC.RESULTS In total 230 patients were finally included in this study,including 154 males(67.0%)and 76 females(33.0%).The mean age was(59.37±10.60)years,ranging from 24 years to 80 years.According to the tumor regression grade standard,there were 95 cases in the obvious response group(grade 0 or grade 1)and 135 cases in the poor response group(grade 2 or grade 3).The obvious response rate was 41.3%.Least absolute shrinkage and selection operator analysis showed that four risk factors significantly related to the efficacy of NAC were tumor location(P<0.001),histological differentiation(P=0.001),clinical T stage(P=0.008),and carbohydrate antigen 724(P=0.008).The C-index for the prediction nomogram was 0.806.The calibration curve revealed that the predicted value exhibited good agreement with the actual value.Decision curve analysis showed that the nomogram had a good value in clinical application.CONCLUSION A nomogram combining tumor location,histological differentiation,clinical T stage,and carbohydrate antigen 724 showed satisfactory predictive power to the response of NAC and can be used by gastrointestinal surgeons to determine the optimal treatment strategies for advanced GC patients.
文摘BACKGROUND The effectiveness of neoadjuvant therapy in esophageal cancer(EC)treatment is still a subject of debate.AIM To compare the clinical efficacy and toxic side effects between neoadjuvant chemoradiotherapy(nCRT)and neoadjuvant chemotherapy(nCT)for locally advanced EC(LAEC).METHODS A comprehensive search was conducted using multiple databases,including PubMed,EMBASE,MEDLINE,Science Direct,The Cochrane Library,China National Knowledge Infrastructure,Wanfang Database,Chinese Science and Technology Journal Database,and Chinese Biomedical Literature Database Article.Studies up to December 2022 comparing nCRT and nCT in patients with EC were selected.RESULTS The analysis revealed significant differences between nCRT and nCT in terms of disease-free survival.The results indicated that nCRT provided better outcomes in terms of the 3-year overall survival rate(OSR)[odds ratio(OR)=0.95],complete response rate(OR=3.15),and R0 clearance rate(CR)(OR=2.25).However,nCT demonstrated a better 5-year OSR(OR=1.02)than nCRT.Moreover,when compared to nCRT,nCT showed reduced risks of cardiac complications(OR=1.15)and pulmonary complications(OR=1.30).CONCLUSION Overall,both nCRT and nCT were effective in terms of survival outcomes for LAEC.However,nCT exhibited better performance in terms of postoperative complications.

文摘BACKGROUND Colorectal cancer is the third most prevalent malignancy globally and ranks second in cancer-related mortality,with the liver being the primary organ of metastasis.Preoperative chemotherapy is widely recommended for initially or potentially resectable colorectal liver metastases(CRLMs).Tumour pathological response serves as the most important and intuitive indicator for assessing the efficacy of chemotherapy.However,the postoperative pathological results reveal that a considerable number of patients exhibit a poor response to preoperative chemotherapy.Body mass index(BMI)is one of the factors affecting the tumori-genesis and progression of colorectal cancer as well as prognosis after various antitumour therapies.Several studies have indicated that overweight and obese patients with metastatic colorectal cancer experience worse prognoses than those with normal weight,particularly when receiving first-line chemotherapy regimens in combination with bevacizumab.AIM To explore the predictive value of BMI regarding the pathologic response following preoperative chemotherapy for CRLMs.METHODS A retrospective analysis was performed in 126 consecutive patients with CRLM who underwent hepatectomy following preoperative chemotherapy at four different hospitals from October 2019 to July 2023.Univariate and multivariate logistic regression models were applied to analyse potential predictors of tumour pathological response.The Kaplan-Meier method with log rank test was used to compare progression-free survival(PFS)between patients with high and low BMI.BMI<24.0 kg/m^(2) was defined as low BMI,and tumour regression grade 1-2 was defined as complete tumour response.RESULTS Low BMI was observed in 74(58.7%)patients and complete tumour response was found in 27(21.4%)patients.The rate of complete tumour response was significantly higher in patients with low BMI(29.7%vs 9.6%,P=0.007).Multivariate analysis revealed that low BMI[odds ratio(OR)=4.56,95%confidence interval(CI):1.42-14.63,P=0.011],targeted therapy with bevacizumab(OR=3.02,95%CI:1.10-8.33,P=0.033),preoperative carcinoembryonic antigen level<10 ng/mL(OR=3.84,95%CI:1.19-12.44,P=0.025)and severe sinusoidal dilatation(OR=0.17,95%CI:0.03-0.90,P=0.037)were independent predictive factors for complete tumour response.The low BMI group exhibited a significantly longer median PFS than the high BMI group(10.7 mo vs 4.7 mo,P=0.011).CONCLUSION In CRLM patients receiving preoperative chemotherapy,a low BMI may be associated with better tumour response and longer PFS.
文摘BACKGROUND Immunotherapy have demonstrated promising outcomes in patients with high microsatellite instability(MSI)(MSI-H)metastatic colorectal cancer.However,the comparative effectiveness of Immunotherapy and chemotherapy for patients with low MSI(MSI-L),and microsatellite stable(MSS)metastatic colorectal cancer remains unclear.AIM To investigate immunotherapy vs chemotherapy for treatment of MSI-L/MSS metastatic colorectal cancer,and to evaluate the success of immunotherapy against chemotherapy in managing MSI-H metastatic colorectal cancer during a follow-up of 50 months.METHODS We conducted a retrospective cohort study using the National Cancer Database(NCDB)to evaluate the overall survival(OS)of patients with metastatic colorectal cancer treated with immunotherapy or chemotherapy.The study population was stratified by MSI status(MSI-H,MSI-L,and MSS).Multivariable Cox proportional hazard models were used to assess the association between treatment modality and OS,adjusting for potential confounders.RESULTS A total of 21951 patients with metastatic colorectal cancer were included in the analysis,of which 2358 were MSI-H,and 19593 were MSI-L/MSS.In the MSI-H cohort,immunotherapy treatment(n=142)was associated with a significantly improved median OS compared to chemotherapy(n=860).After adjusting for potential confounders,immunotherapy treatment remained significantly associated with better OS in the MSI-H cohort[adjusted hazard ratio(aHR):0.57,95%confidence interval(95%CI):0.43-0.77,P<0.001].In the MSS cohort,no significant difference in median OS was observed between immunotherapy treatment and chemotherapy(aHR:0.94,95%CI:0.69-1.29,P=0.715).CONCLUSION In this population-based study using the NCDB,immunotherapy treatment was associated with significantly improved OS compared to chemotherapy in patients with MSI-H metastatic colorectal cancer,but not in those with MSI-L/MSS metastatic colorectal cancer.Further studies are warranted to determine the optimal therapeutic approach for patients with MSI-L/MSS metastatic colorectal cancer.
文摘BACKGROUND Gallbladder cancer is the most common malignancy of the biliary tract.Neo-adjuvant chemotherapy(NACT)has improved overall survival by enabling R0 resection.Currently,there is no consensus of guidelines for neoadjuvant therapy in gallbladder cancer.As investigations continue to analyze the regimen and benefit of NACT for ongoing care of gallbladder cancer patients,we examined American College of Surgeons National Surgical Quality Improvement Program(NSQIP)database to determine if there was higher morbidity among the neo-adjuvant group within the 30-day post-operative period.We hypothesized patients who underwent NACT were more likely to have higher post-operative morbidity.AIM To investigate the 30-day post-operative morbidity outcomes between patients who received NACT and underwent surgery and patients who only had surgery.METHODS A retrospective analysis of the targeted hepatectomy NSQIP data between 2015 and 2019 was performed to determine if NACT in gallbladder cancer increased the risk for post-operative morbidity(bile leak,infection rate,rate of converting to open surgery,etc.)compared to the group who only had surgery.To calculate the odds ratio for the primary and secondary outcomes,a crude logistic regression was performed.RESULTS Of the 452 patients,52 patients received NACT prior to surgery.There were no statistically significant differences in the odds of morbidity between the two groups,including bile leak[odds ratio(OR),0.69;95%confidence interval(95%CI):0.16-2.10;P=0.55],superficial wound infection(OR,0.58;95%CI:0.03-3.02;P=0.61),and organ space wound infection(OR,0.63;95%CI:0.18-1.63;P=0.61).CONCLUSION There was no significant difference in the risk of 30-day post-operative morbidity between the NACT and surgery group and the surgery only group.
文摘Objective: Both chemotherapy and radiotherapy have demonstrated high effectiveness as the best mechanisms in the fight against cancer;however, various studies seem to confirm that they could also favor the development of other unwanted effects of great importance for the patient. The main objective of this study is to find out the possible existence of this type of links. Method: This is a systematic literature review that seeks to find out which and how long cases of late interactions related to chemotherapy and radiotherapy treatments have been known. The bibliographic review was carried out based on references published in the last five years. Results: Various studies confirm the possible relationship between chemotherapy and radiotherapy treatments with the development of new undesirable side effects, especially as a consequence of the hepatotoxicity generated in the case of chemotherapy and radiation in radiotherapy. However, in this last type of treatment, the problems raised are really few. Conclusions: The existence of a risk of suffering new unwanted side effects after different types of treatment seems to have been demonstrated, especially in the case of chemotherapy. In the case of radiotherapy, adverse effects are practically non-existent, although they are no less important.

文摘BACKGROUND Hepatic arterial infusion chemotherapy(HAIC)has been proven to be an ideal choice for treating unresectable hepatocellular carcinoma(uHCC).HAIC-based treatment showed great potential for treating uHCC.However,large-scale studies on HAIC-based treatments and meta-analyses of first-line treatments for uHCC are lacking.AIM To investigate better first-line treatment options for uHCC and to assess the safety and efficacy of HAIC combined with angiogenesis inhibitors,programmed cell death of protein 1(PD-1)and its ligand(PD-L1)blockers(triple therapy)under real-world conditions.METHODS Several electronic databases were searched to identify eligible randomized controlled trials for this meta-analysis.Study-level pooled analyses of hazard ratios(HRs)and odds ratios(ORs)were performed.This was a retrospective single-center study involving 442 patients with uHCC who received triple therapy or angiogenesis inhibitors plus PD-1/PD-L1 blockades(AIPB)at Sun Yat-sen University Cancer Center from January 2018 to April 2023.Propensity score matching(PSM)was performed to balance the bias between the groups.The Kaplan-Meier method and cox regression were used to analyse the survival data,and the log-rank test was used to compare the suvival time between the groups.RESULTS A total of 13 randomized controlled trials were included.HAIC alone and in combination with sorafenib were found to be effective treatments(P values for ORs:HAIC,0.95;for HRs:HAIC+sorafenib,0.04).After PSM,176 HCC patients were included in the analysis.The triple therapy group(n=88)had a longer median overall survival than the AIPB group(n=88)(31.6 months vs 14.6 months,P<0.001)and a greater incidence of adverse events(94.3%vs 75.4%,P<0.001).CONCLUSION This meta-analysis suggests that HAIC-based treatments are likely to be the best choice for uHCC.Our findings confirm that triple therapy is more effective for uHCC patients than AIPB.
文摘BACKGROUND SMARCA4 is a component of chromatin remodeling of SWItch/sucrose-nonfermenting(SWI/SNF)complexes and plays an essential role in oncogenesis.SMARCA4-deficient malignancies arising from the gastrointestinal tract are rare and have a poor prognosis.There is no standard treatment for advanced and undifferentiated SMARCA4-deficient duodenal malignancies.Programmed death 1(PD-1)antibodies,known as immune checkpoint inhibitor antibodies,potentially play a role in treating gastrointestinal tract malignancies.CASE SUMMARY We present two patients with SMARCA4 deficiency and TP53 gene mutation in advanced undifferentiated carcinomas of the duodenum.For both patients,SMARCA4 deficiency was confirmed by immunohistochemical staining for the BRG1 protein,while TP53 gene mutations were observed via next-generation sequencing.Both patients were administered chemotherapy in combination with an anti-PD-1 antibody.The two patients exhibited completely different responses to treatment and had different prognoses.Case 1 experienced rapid progression after PD-1 infusion and chemotherapy,case 2 experienced a remarkable response after treatment,and the progression-free survival was more than 6 months.CONCLUSION This study described our clinical and pathological observations of SMARCA4-deficient advanced undifferentiated carcinoma of the duodenum.PD-1 combined with chemotherapy showed a certain efficacy in select patients,providing options for treating these highly malignant tumors.Patients with liver metastases had a worse prognosis than did those with only lymph node metastasis.
文摘BACKGROUND Lung cancer(LC)is a global medical,social and economic problem and is one of the most common cancers and the leading cause of mortality from malignant neoplasms.LC is characterized by an aggressive course,and in the presence of disease recurrence risk factors,patients,even at an early stage,may be indicated for adjuvant therapy to improve survival.However,combined treatment does not always guarantee a favorable prognosis.In this regard,establishing predictors of LC recurrence is highly important both for determining the optimal treatment plan for the patients and for evaluating its effectiveness.AIM To establish predictors of disease recurrence after radical resection and adjuvant chemotherapy in patients with stage IIb-IIIa lung squamous cell carcinoma(LSCC).METHODS A retrospective case-control cohort study included 69 patients with LSCC who underwent radical surgery at the Orenburg Regional Clinical Oncology Center from 2009 to 2018.Postoperatively,all patients received adjuvant chemotherapy.Histological samples of the resected lung were stained with Mayer's hematoxylin and eosin and examined under a light microscope.Univariate and multivariate analyses were used to identify predictors associated with the risk of disease recurrence.Receiver operating characteristic curves were constructed to discriminate between patients with a high risk of disease recurrence and those with a low risk of disease recurrence.Survival was analyzed using the Kaplan-Meier method.The log-rank test was used to compare survival curves between patient subgroups.Differences were considered to be significant at P<0.05.RESULTS The following predictors of a high risk of disease recurrence in patients with stage IIb-IIa LSCC were established:a low degree of tumor differentiation[odds ratio(OR)=7.94,95%CI=1.08-135.81,P=0.049];metastases in regional lymph nodes(OR=5.67,95%CI=1.09-36.54,P=0.048);the presence of loose,fine-fiber connective tissue in the tumor stroma(OR=21.70,95%CI=4.27-110.38,P=0.0002);and fragmentation of the tumor solid component(OR=2.53,95%CI=1.01-12.23,P=0.049).The area under the curve of the predictive model was 0.846(95%CI=0.73-0.96,P<0.0001).The sensitivity,accuracy and specificity of the method were 91.8%,86.9%and 75.0%,respectively.In the group of patients with a low risk of LSCC recurrence,the 1-,2-and 5-year disease-free survival(DFS)rates were 84.2%,84.2%and 75.8%,respectively,while in the group with a high risk of LSCC recurrence the DFS rates were 71.7%,40.1%and 8.2%,respectively(P<0.00001).Accordingly,in the first group of patients,the 1-,2-and 5-year overall survival(OS)rates were 94.7%,82.5%and 82.5%,respectively,while in the second group of patients,the OS rates were 89.8%,80.1%and 10.3%,respectively(P<0.00001).CONCLUSION The developed method allows us to identify a group of patients at high risk of disease recurrence and to adjust to ongoing treatment.

文摘Background:Neoadjuvant chemotherapy plays a vital role in the treatment of advanced gastric cancer(GC),however,optimizing its effectiveness remains an important research focus.Traditional Chinese medicine(TCM),a promising adjunctive therapy,has shown enhanced clinical outcomes when combined with postoperative adjuvant chemotherapy.Therefore,this study is designed to evaluate the clinical efficacy of Yiqi Huayu Jiedu decoction combined with neoadjuvant chemotherapy FLOT in the treatment of advanced GC.Methods:This study is a prospective,double-arm,randomized controlled trial.It involves a total of 260 patients diagnosed with advanced GC,who will be randomly assigned to two groups-a TCM treatment group and a control group,each comprising 130 patients.All patients will receive standard FLOT chemotherapy,and patients in the TCM treatment group will additionally receive TCM treatment with Yiqi Huayu Jiedu decoction.After four cycles of chemotherapy,GC D2 radical surgery will be performed.The primary objective is to evaluate the postoperative pathological response rate of the tumor.The secondary objectives include evaluating the perioperative nutritional status,the efficacy of TCM syndrome,and adverse events associated with both chemotherapy and surgery.Discussion:Currently,no trials have investigated the impact of TCM in combination with neoadjuvant chemotherapy on the preoperative treatment in patients with advanced GC.Accordingly,it is imperative to conduct this prospective study to evaluate the clinical efficacy and safety of this regimen,meanwhile providing high-level clinical evidence for TCM combined with neoadjuvant chemotherapy and introducing an innovative regimen for preoperative comprehensive treatment of GC.
文摘BACKGROUND The combination of programmed cell death protein-1(PD-1)inhibitor and che-motherapy is approved as a standard first-or second-line treatment in patients with advanced oesophageal or gastric cancer.However,it is unclear whether this combination is superior to chemotherapy alone.AIM To assess the comparative effectiveness and tolerability of combining PD-1 inhibitors with chemotherapy vs chemotherapy alone in patients with advanced gastric cancer,gastroesophageal junction(GEJ)cancer,or oesophageal carcinoma.METHODS We searched the PubMed and Embase databases for studies that compared the efficacy and tolerance of PD-1 inhibitors in combination with chemotherapy vs chemotherapy alone in patients with advanced oesophageal or gastric cancer.We employed either random or fixed models to analyze the outcomes of each clinical trial,en-compassing data on overall survival(OS),progression-free survival(PFS),objective response rate,and adverse events(AEs).RESULTS Nine phase 3 clinical trials(7016 advanced oesophageal and gastric cancer patients)met the inclusion criteria.Our meta-analysis demonstrated that the pooled PD-1 inhibitor+chemotherapy group had a significantly longer OS than the chemotherapy-alone group[hazard ratio(HR)=0.76,95%confidence interval(CI):0.71-0.81];the pooled PFS result was consistent with that of OS(HR=0.67,95%CI:0.61-0.74).The count of patients achieving an objective response in the PD-1 inhibitor+chemotherapy group surpassed that of the chemotherapy-alone group[odds ratio(OR)=1.86,95%CI:1.59-2.18].AE incidence was also higher in the combination-therapy group than in the chemotherapy-alone group,regardless of whether≥grade 3 only(OR=1.30,95%CI:1.07-1.57)or all AE grades(OR=1.88,95%CI:1.39-2.54)were examined.We performed a subgroup analysis based on the programmed death-ligand 1(PD-L1)combined positive score(CPS)and noted extended OS and PFS durations within the CPS≥1,CPS≥5,and CPS≥10 subgroups of the PD-1 inhibitor+chemotherapy group.CONCLUSION In contrast to chemotherapy alone,the combination of PD-1 inhibitor and chemotherapy appears to present a more favorable option for initial or subsequent treatment in patients with gastric cancer,GEJ tumor,or oesophageal cancer.This holds true particularly for individuals with PD-L1 CPS scores of≥5 and≥10.
文摘Objective:To evaluate symptom experience and quality of life(QoL)and to identify the predictors of QoL among colorectal cancer patients undergoing chemotherapy.Methods:A cross-sectional study was conducted on 107 colorectal cancer patients at a university-affiliated hospital between June 1 and July 30,2021.Functional Assessment of Cancer Therapy-Colorectal(FACT-C)and Memorial Symptom Assessment Scale-Short Form(MSAS-SF)were used to assess symptom experience and QoL of these patients.Data were analyzed using Pearson’s correlation,t-test,ANOVA,and hierarchical multiple regression.Results:The mean QoL score for colorectal cancer patients was 88.78±20.08.The most frequently experienced physical and psychological symptoms were numbness/tingling and worrying.Physical and psychological symptoms have a significant negative association with QoL.Perceived economic status was significantly associated with QoL in patients’general characteristics.The regression analyses showed that high psychological symptoms(β=-0.63,P<0.001),middle perceived economic status(β=-0.22,P=0.009),and low perceived economic status(β=-0.36,P<0.001)were statistically significant in predicting patients’low QoL.Conclusion:Symptom experience and QoL are essential variables that should be acknowledged when delivering health care to colorectal cancer patients.More attention to the reduction and comprehensive symptom management of psychological distress could improve QoL among colorectal cancer patients.

文摘BACKGROUND Obstruction or fullness after feeding is common in gastric cancer(GC)patients,affecting their nutritional status and quality of life.Patients with digestive obstruction are generally in a more advanced stage.Existing methods,including palliative gastrectomy,gastrojejunostomy,endoluminal stent,jejunal nutrition tube and intravenous chemotherapy,have limitations in treating these symptoms.AIM To analyze the efficacy of continuous gastric artery infusion chemotherapy(cGAIC)in relieving digestive obstruction in patients with advanced GC.METHODS This study was a retrospective study.Twenty-nine patients with digestive obstruction of advanced GC who underwent at least one cycle of treatment were reviewed at The Second Affiliated Hospital of Zhejiang University School of Medicine.The oxaliplatin-based intra-arterial infusion regimen was applied in all patients.Mild systemic chemotherapy was used in combination with local treatment.The clinical response was evaluated by contrast-enhanced computed tomography using Response Evaluation Criteria In Solid Tumors(RECIST)criteria.Digestive tract symptoms and toxic effects were analyzed regularly.A comparison of the Karnofsky Performance Status(KPS)score and Stooler’s Dysphagia Score before and after therapy was made.Univariate survival analysis and multivariate survival analysis were also performed to explore the key factors affecting patient survival.RESULTS All patients finished cGAIC successfully without microcatheter displacement,as confirmed by arteriography.The median follow-up time was 24 mo(95%CI:20.24-27.76 mo).The overall response rate was 89.7%after cGAIC according to the RECIST criteria.The postoperative Stooler’s Dysphagia Score was significantly improved.Twentytwo(75.9%)of the 29 patients experienced relief of digestive obstruction after the first two cycles,and 13(44.8%)initially unresectable patients were then considered radically resectable.The median overall survival time(mOS)was 16 mo(95%CI:9.32-22.68 mo).Patients who received radical surgery had a significantly longer mOS than other patients(P value<0.001).Multivariate Cox regression analysis indicated that radical resection after cGAIC,intravenous chemotherapy after cGAIC,and immunotherapy after cGAIC were independent predictors of mOS.None of the patients stopped treatment because of adverse events.CONCLUSION cGAIC was effective and safe in relieving digestive obstruction in advanced GC,and it could improve surgical conversion possibility and survival time.

文摘objective:Two cycles of induction chemotherapy(IC)followed by 2 cycles of platinum-based concurrent chemoradiotherapy(CCRT)(2IC+2CCRT)for locoregionally advanced nasopharyngeal carcinoma(LA-NPC)is widely adopted but not evidence-confirmed.This study aimed to determine the clinical value of 2IC+2CCRT regarding efficacy,toxicity and cost-effectiveness.Methods:This real-world study from two epidemic centers used propensity score matching(PSM)and inverse probability of treatment weighting(IPTW)analyses.The enrolled patients were divided into three groups based on treatment modality:Group A(2IC+2CCRT),Group B(3IC+2CCRT or 2IC+3CCRT)and Group C(3IC+3CCRT).Long-term survival,acute toxicities and cost-effectiveness were compared among the groups.We developed a prognostic model dividing the population into high-and low-risk cohorts,and survivals including overall survival(OS),progression-free survival(PFS),distant metastasis-free survival(DMFS)and locoregional relapse-free survival(LRRFS)were compared among the three groups according to certain risk stratifications.Results:Of 4,042 patients,1,175 were enrolled,with 660,419,and 96 included in Groups A,B and C,respectively.Five-year survivals were similar among the three groups after PSM and confirmed by IPTW.Grade 3-4 neutropenia and leukocytopenia were significantly higher in Groups C and B than in Group A(52.1%vs.41.5%vs.25.2%;41.7%vs.32.7%vs.25.0%)as were grade 3-4 nausea/vomiting and oral mucositis(29.2%vs.15.0%vs.6.1%;32.3%vs.25.3%vs.18.0%).Cost-effective analysis suggested that 2IC+2CCRT was the least expensive,while the health benefits were similar to those of the other groups.Further exploration showed that 2IC+2CCRT tended to be associated with a shorter PFS in high-risk patients,while 3IC+3CCRT potentially contributed to poor PFS in low-risk individuals,mainly reflected by LRRFS.Conclusions:In LA-NPC patients,2IC+2CCRT was the optimal choice regarding efficacy,toxicity and costeffectiveness;however,2IC+2CCRT and 3IC+3CCRT probably shortened LRRFS in high-and low-risk populations,respectively.
文摘BACKGROUND Gastric cancer is one of the most common cancers worldwide, with a 5-year survival rate of only 20%. The age of onset of gastric cancer is in line with the general rule of cancer. Most of them occur after middle age, mostly between 40and 60 years old, with an average age of about 50 years old, and only 5% of patients are under 30 years old. The incidence of male is higher than that of female.AIM To investigate the short-term efficacy and influencing factors of chemotherapy combined with irinotecan in patients with advanced gastric cancer.METHODS Eighty patients with advanced gastric cancer who were treated in our hospital from January 2019 to January 2022 were selected. The patients were divided into an observation group(n = 40) and control group(n = 40) by the envelope method.The control group was given preoperative routine chemotherapy. The observation group was treated with irinotecan in addition to the chemotherapy given to the control group. The short-term efficacy of treatment in the two groups, as well as tumor marker levels and quality of life before and after treatment were evaluated.RESULTS The short-term treatment effect in the observation group was better than that in the control group(P < 0.05), and the total effective rate was 57.50%. The age and proportion of tumor node metastasis(TNM) stage IV patients with ineffective chemotherapy in the observation group were(65.12 ± 5.71) years and 52.94%,respectively, which were notably higher than those of patients with effective chemotherapy(P < 0.05), while the Karnofsky Performance Scale score was(67.70± 3.83) points, which was apparently lower than that of patients with effective chemotherapy(P <0.05). After 3 mo of treatment, the SF-36 scale scores of physiological function, energy, emotional function, and mental health in the observation group were 65.12 ± 8.14, 54.76 ± 6.70, 47.58 ± 7.22,and 66.16 ± 8.11 points, respectively, which were considerably higher than those in the control group(P < 0.05). The incidence rates of grade Ⅲ-Ⅳ diarrhea and grade Ⅲ-Ⅳ thrombocytopenia in the observation group were 32.50% and 25.00%, respectively, which were markedly higher than those in the control group(P < 0.05).CONCLUSION Chemotherapy combined with irinotecan in patients with advanced gastric cancer has a good short-term efficacy and can significantly reduce serum tumor markers and improve the quality of life of patients. The efficacy may be affected by the age and TNM stage of the patients, and its long-term efficacy needs further study.
