Hence, exploring with real world evidence (RWE) clinicians’ preferences for treatment options and their results seems pertinent. Methods: In a set of consecutive patients with localized pancreatic cancer assisted in a third level hospital from January 2013 to December 2022, medical records, symptoms, diagnostic process, distribution between subtypes, and treatment plans, with safety and efficacy results, were assessed. Results: A total of 152 patients with localized disease were included (43.4% R, 21.0% BR, 33.6% LAU). The population characteristics exemplified differences between daily practice and clinical trials. Tumor location and symptoms were as expected. Treatment plan was conditioned by PS or comorbidities in 23.0% of patients. In patients with R disease, surgery followed by different adjuvant chemotherapy (CT) regimes was the antineoplastic treatment of choice (64.8%) with efficacy results (OS 37.5 months;95% CI 18.4 - 56.7), in the range of contemporary standards. The common use of neoadjuvant CT for BR disease (94.4%), with surgery in 50% of them, and its results (OS 30.8 months;95% CI 10.5 - 51.2) reflected current controversies of treatment recommendations and evolution in this scenario. Paliative CT with or without radiotherapy was the standard specific treatment in LAU disease (95.1%) with survival results (PFS: 10.8 months;95% CI 8.8 - 12.7. OS: 20.3 months;95% CI 13.5 - 27.2) that justify the distinct character and the specific study of this entity. Conclusion: RWE for localized pancreatic cancer aroused from the analysis of this population confirms the distinct nature of patients assisted in daily practice, as well as mirrors the complexity of decision making in clinical assumptions in which achieving stronger evidence should be paramount.展开更多

This study aims to determine the therapeutic itinerary of patients followed for connectivitis in the Internal Medicine Department of the CNHU HKM of Cotonou. <strong>Methodology:</strong> This is a cross-sectional study that included patients followed for connectivitis in the HKM-Cotonou Internal Medicine Department from January 2010 to October 2018. <strong>Results:</strong> Out of 3600 patients hospitalized in the study period, 21 had connectivitis, <i>i.e.</i> a hospital frequency of 0.58%. Of the 21 patients collected, 18 met the inclusion criteria. The mean age was 40 (±11) years old and the youngest was of 21 and the oldest 58. The sex ratio was 17.9. The “Fon” ethnic group was the most represented (33.3%) and 15 (83.3%) subjects were Christians. Systemic lupus erythematosus was the most frequent connectivitis (55.6%). The average time of consultation was 38 months. Witchcraft was the most incriminating cause (78%). Ten (55.5%) patients had resorted to self-medication as their first choice of treatment, 5 (27.8%) to traditional medicine treatment and 3 (16.7%) to prayer for healing. The reasons for the first choice of treatment were satisfaction (44.4%), financial problems (27.8%), trivialization of the disease (16.7%), and advice from family and friends (11.1%). The consultation at the CNHU followed a referral from a first contact health structure (61%) or an initiative of the patient (27.8%). <strong>Conclusion:</strong> Connectivitis is a source of diagnostic error in our context. Awareness must be raised among patients for an early consultation at the first symptoms.展开更多

Fluorouracil-based adjuvant chemotherapy was administered after surgery at the discretion of the physician. Adjusted multivariate regression models were used to evaluate the association between adjuvant chemotherapy and survival outcomes.RESULTS Of the total 104 patients who underwent curative surgery, 52 received adjuvant chemotherapy. Multivariate analysis revealed that higher histologic grade [hazard ratio(HR) = 2.24, P = 0.046], advanced tumor stage(HR = 1.85, P = 0.030), and vascular invasion(HR = 2.14, P = 0.010) were associated with shorter DFS. Adjuvant chemotherapy improved DFS compared to the observation group(HR =0.50, P = 0.015) and tended to be associated with a longer OS, although the difference was not statistically significant(HR = 0.58, P = 0.098).CONCLUSION Among patients with resected AoV carcinoma, the adjuvant chemotherapy group was not associated with a significant survival benefit compared to the observation group. However, on multivariate analysis adjusting for prognostic factors, adjuvant chemotherapy following surgery was an independent prognostic factor for DFS in patients with resected AoV carcinoma. Further studies are needed to investigate the effectiveness of adjuvant chemotherapy according to histologic phenotype.展开更多

Only the biopsy allows the certainty diagnosis. The aim was to report a first case of small cell lymphoma of the gastrocnemius in Mali and to do a review of the literature. Clinical Observation: It was about a 34-year-old woman who consulted 3 months after the onset of symptoms for swelling and pain in the left calf. On clinical examination there was a hard, painful and warm mass in the left calf, with paresthesias in the tibial nerve territory associated with partial functional impotence of the leg. The ultrasound revealed a hyper echogenic and heterogeneous non-vascularized mass of the left gastrocnemius muscle measuring 65 × 45 × 40 mm non-vascularized on color Doppler and pulsed in favor of myositis. Magnetic resonance imaging (MRI) concluded in a well-limited heterogeneous cystic mass in the left gastrocnemius muscle respecting the bone of benign appearance: remodeled Baker’s cyst? Considering the radioclinical unconformity, thoraco-abdominal CT was performed and revealed pulmonary metastasis. The biopsy carried out concluded with a small cell lymphoma of the gastrocnemial muscle. Marginal resection was performed associated with adjuvant chemotherapy. The advancement at 9 months was satisfactory.展开更多

Objective: This study aimed to determine the gynecological side effects of tamoxifen among Sudanese women who have been diagnosed with breast cancer in Khartoum, Sudan. Methods: A retrospective cross-sectional study was conducted at Alzara Hospital in Al Amal Toure Revere, Sudan. A convenience sample of individuals previously diagnosed with breast cancer attended refer clinic. From October 2020 to September 2021, all patients attending were checked for eligibility. Results: A total of 100 patients were enrolled in the study;60% of patients reported increased vaginal secretions after taking the drug, 28% reported normal vaginal secretions with no change, and 11% reported decreased secretions after taking the medication, while 22% developed vaginal bleeding, and 22% of the ultrasound results revealed endometrial masses among the study patients. Also, 54 percent of female patients experienced hot flashes after taking the medication, and 12% of women missed some doses of treatment. Conclusion: Tamoxifen results in several gynecological side effects in women with breast cancer. A high percentage of women in the study developed hot flashes, vaginal bleeding, and discharge, in addition to having ultrasound results showing endometrial masses among them.展开更多

文摘Background: Localized pancreatic cancer, including resectable (R), borderline resectable (BR) and locally advanced unresectable disease (LAU), is considered in clinical guidelines for diverse treatment options based on clinical trials in selected populations. Hence, exploring with real world evidence (RWE) clinicians’ preferences for treatment options and their results seems pertinent. Methods: In a set of consecutive patients with localized pancreatic cancer assisted in a third level hospital from January 2013 to December 2022, medical records, symptoms, diagnostic process, distribution between subtypes, and treatment plans, with safety and efficacy results, were assessed. Results: A total of 152 patients with localized disease were included (43.4% R, 21.0% BR, 33.6% LAU). The population characteristics exemplified differences between daily practice and clinical trials. Tumor location and symptoms were as expected. Treatment plan was conditioned by PS or comorbidities in 23.0% of patients.

The “Fon” ethnic group was the most represented (33.3%) and 15 (83.3%) subjects were Christians. Systemic lupus erythematosus was the most frequent connectivitis (55.6%). The average time of consultation was 38 months. Witchcraft was the most incriminating cause (78%). Ten (55.5%) patients had resorted to self-medication as their first choice of treatment, 5 (27.8%) to traditional medicine treatment and 3 (16.7%) to prayer for healing. The reasons for the first choice of treatment were satisfaction (44.4%), financial problems (27.8%), trivialization of the disease (16.7%), and advice from family and friends (11.1%). The consultation at the CNHU followed a referral from a first contact health structure (61%) or an initiative of the patient (27.8%). <strong>Conclusion:</strong> Connectivitis is a source of diagnostic error in our context. Awareness must be raised among patients for an early consultation at the first symptoms.

文摘Background Non-exercise estimated cardiorespiratory fitness(NEE-CRF)has been shown to be associated with mortality,although its association with cancer incidence is unknown.The study aimed to assess the prospective association between NEE-CRF and cancer incidence in a large cohort of men and women.Methods The National Institutes of Health-American Association of Retired Persons diet and health study is a prospective cohort that included 402,548 participants aged 50–71 years who were free from cancer at baseline(1995–1996)(men(n=238,835)and women(n=163,713))and were followed until December 31,2015.The exposure variable was NEE-CRF expressed in metabolic equivalents.NEE-CRF was estimated using a validated equation of self-reported predictors on demographics and lifestyle behaviors derived from baseline questionnaires.Primary outcomes were total cancer incidence and incidence of prostate,breast,lung,and colorectal cancers.Cox proportional hazards models were analyzed for the association between NEE-CRF and cancer incidence outcomes adjusted for established cancer risk factors.Results During 13.7±3.2 years of follow-up(mean±SD),64,344 men and 31,315 women developed a new cancer.For every 1-metabolic equivalent higher NEE-CRF,the hazard ratios and 95%confidence intervals(95%CIs)were 0.96(95%CI:0.94–0.97)and 0.88(95%CI:0.84–0.92)of total and colorectal cancer incidence among men,and 0.95(95%CI:0.93–0.97)and 0.94(95%CI:0.91–0.97)of total and breast cancer incidence among women,respectively(all p<0.001).NEE-CRF was not associated with incidence of prostate and lung cancers in men or colorectal and lung cancers in women.Conclusion These results suggest that higher CRF levels,as assessed by the applied non-exercise estimated method,may provide preventive benefits against the development of cancer,while low CRF could potentially serve as a modifiable cancer risk factor.Integrating NEE-CRF into screening paradigms and referring low-fit individuals to improve CRF could complement the public health prevention strategy against cancer.
文摘Coronavirus disease 2019(COVID-19),caused by severe acute respiratory syndrome coronavirus 2,broke out in December 2019 in Wuhan city of China and spread rapidly worldwide.Therefore,by March 2020,the World Health Organization declared the disease a global pandemic.Apart from the respiratory system,various other organs of the human body are also seriously affected by the virus.Liver injury in patients with a severe form of COVID-19 is estimated to be 14.8%-53.0%.Elevated levels of total bilirubin,aspartate aminotransferase and alanine aminotransferase and low levels of serum albumin and prealbumin are the main laboratory findings.Patients with pre-existing chronic liver disease and cirrhosis are much more prone to develop severe liver injury.This literature review presented the recent scientific findings regarding the pathophysiological mechanisms responsible for liver injury in critically ill patients with COVID-19,the various interactions between drugs used to treat the disease and the function of the liver and the specific tests providing the possibility of early diagnosis of severe liver injury in these patients.Moreover,it highlighted the burden that COVID-19 put on health systems worldwide and its effect on transplant programs and the care provided to critically ill patients in general and particularly to those with chronic liver disease.
文摘Gastric cancer (GC) is a major health concern globally,ranking fifth in frequency and fourth in cancer-associated mortality1.In China,an estimated 396,500 new cases are diagnosed each year,and late-stage disease comprises more than 80%of cases2.Because of late diagnosis and heterogeneous characteristics,the prognosis of GC remains poor.For patients with advanced disease,traditional chemotherapy has been the mainstay of treatment,but its clinical outcomes are far from satisfactory,with a 5-year survival rate below 10%.
文摘BACKGROUND Owing to rarity of disease and lack of prospective studies, data supporting the role of adjuvant chemotherapy in ampulla of Vater(AoV) carcinoma is limited.AIM To evaluate whether adjuvant chemotherapy cases for AoV carcinoma had better disease-free survival(DFS) rates than cases of observation following curative surgery.METHODS We retrospectively analyzed the association between adjuvant chemotherapy and DFS and overall survival(OS) in patients with stage IB-Ⅲ AoV carcinoma who underwent curative surgical resection. Fluorouracil-based adjuvant chemotherapy was administered after surgery at the discretion of the physician. Adjusted multivariate regression models were used to evaluate the association between adjuvant chemotherapy and survival outcomes.RESULTS Of the total 104 patients who underwent curative surgery, 52 received adjuvant chemotherapy. Multivariate analysis revealed that higher histologic grade [hazard ratio(HR) = 2.24, P = 0.046], advanced tumor stage(HR = 1.85, P = 0.030), and vascular invasion(HR = 2.14, P = 0.010) were associated with shorter DFS. Adjuvant chemotherapy improved DFS compared to the observation group(HR =0.50, P = 0.015) and tended to be associated with a longer OS, although the difference was not statistically significant(HR = 0.58, P = 0.098).CONCLUSION Among patients with resected AoV carcinoma, the adjuvant chemotherapy group was not associated with a significant survival benefit compared to the observation group. However, on multivariate analysis adjusting for prognostic factors, adjuvant chemotherapy following surgery was an independent prognostic factor for DFS in patients with resected AoV carcinoma. Further studies are needed to investigate the effectiveness of adjuvant chemotherapy according to histologic phenotype.
文摘Introduction: The primary localization of non-Hodgkin lymphoma of the muscle is rare. Only the biopsy allows the certainty diagnosis. The aim was to report a first case of small cell lymphoma of the gastrocnemius in Mali and to do a review of the literature. Clinical Observation: It was about a 34-year-old woman who consulted 3 months after the onset of symptoms for swelling and pain in the left calf. On clinical examination there was a hard, painful and warm mass in the left calf, with paresthesias in the tibial nerve territory associated with partial functional impotence of the leg. The ultrasound revealed a hyper echogenic and heterogeneous non-vascularized mass of the left gastrocnemius muscle measuring 65 × 45 × 40 mm non-vascularized on color Doppler and pulsed in favor of myositis. Magnetic resonance imaging (MRI) concluded in a well-limited heterogeneous cystic mass in the left gastrocnemius muscle respecting the bone of benign appearance: remodeled Baker’s cyst? Considering the radioclinical unconformity, thoraco-abdominal CT was performed and revealed pulmonary metastasis. The biopsy carried out concluded with a small cell lymphoma of the gastrocnemial muscle. Marginal resection was performed associated with adjuvant chemotherapy. The advancement at 9 months was satisfactory.
文摘Background: In Sudan, the common endocrine therapy tamoxifen is prescribed to HR-positive patients, which is associated with a variety of complications such as hot flashes, vaginal discharge, and vaginal dryness. Objective: This study aimed to determine the gynecological side effects of tamoxifen among Sudanese women who have been diagnosed with breast cancer in Khartoum, Sudan. Methods: A retrospective cross-sectional study was conducted at Alzara Hospital in Al Amal Toure Revere, Sudan. A convenience sample of individuals previously diagnosed with breast cancer attended refer clinic. From October 2020 to September 2021, all patients attending were checked for eligibility. Results: A total of 100 patients were enrolled in the study;60% of patients reported increased vaginal secretions after taking the drug, 28% reported normal vaginal secretions with no change, and 11% reported decreased secretions after taking the medication, while 22% developed vaginal bleeding, and 22% of the ultrasound results revealed endometrial masses among the study patients. Also, 54 percent of female patients experienced hot flashes after taking the medication, and 12% of women missed some doses of treatment. Conclusion: Tamoxifen results in several gynecological side effects in women with breast cancer. A high percentage of women in the study developed hot flashes, vaginal bleeding, and discharge, in addition to having ultrasound results showing endometrial masses among them.
文摘BACKGROUND Sunitinib,a multi-targeted tyrosine kinase inhibitor(TKI),has been approved for the salvage treatment of gastrointestinal stromal tumors(GIST).Hyperammonemic encephalopathy is a rare but severe complication of sunitinib use.Here,we present the case of a 66-year-old male with metastatic GIST without underlying liver cirrhosis who developed sunitinib-induced hyperammonemic encephalopathy.CASE SUMMARY A 66-year-old male with metastatic GIST was admitted because of reduced consciousness.Imatinib was administered as the first-line systemic therapy.He experienced repeated episodes of peritonitis due to tumor perforation,and surgery was performed.Progressive disease was confirmed based on increased liver metastasis,and sunitinib was initiated as a salvage treatment.However,23 d after the third course of sunitinib,he presented to the emergency room with an episode of altered consciousness and behavioral changes.Based on the patient clinical history and examination findings,sunitinib-induced encephalopathy was suspected.Sunitinib was discontinued,and the patient was treated for hyperammonemia.The patient had a normal level of consciousness four days later,and the serum ammonia level gradually decreased.No further neurological symptoms were reported in subsequent follow-ups.CONCLUSION TKI-induced hyperammonemic encephalopathy is potentially life-threatening.Patients receiving TKIs experiencing adverse reactions should undergo systemic evaluation and prompt treatment.

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.
