Comparison of efficacy and safety of 5-FU or capecitabine combined with cisplatin and docetaxel (mDCF and mDCX) as a first-line chemotherapy regimen in her 2-negative metastatic gastric cancer patients: A retrospective study.

The prognosis of metastatic gastric cancer (GC) is poor, with a median survival time of less than a year. Capecitabine is a prodrug, metabolized by thymidine phosphorylase to its cytotoxic metabolite (5-FU). Few studies have compared capecitabine and 5-FU in mGC. In this retrospective study, we compared the efficacy and safety of modified DCF (mDCF) (docetaxel, cisplatin, and 5-FU) and modified DCX (mDCX) (docetaxel, cisplatin, and capecitabine) regimens for first-line treatment in patients with mGC. The study included 112 mGC patients treated with either mDCF (n = 69) or mDCX (n = 43) between 2010 and 2021. Demographic data, response rate, progression-free survival (PFS), overall survival (OS), and adverse events were evaluated. The complete response rate in the mDCF group was 10.1%, whereas the complete response rate in the mDCX group was 2.3%. The partial response rate for mDCF and mDCX were 29% and 37%, respectively. The 2 treatment arms of the study had the same objective rate of response and disease control rate (DCR). PFS and OS rates were comparable between the 2 groups. The median PFS in the mDCF and mDCX arms were 6.0 months (95% CI, 4.87-7.14) and 5.0 months (95% CI, 4.10-5.90) respectively (P = .08). The median OS in the mDCF and mDCX arms were 9.0 months (95% CI, 7.53-10.47) and 9.0 months (95% CI, 6.87-11.11) respectively (P = .07). Neutropenia, asthenia, stomatitis, and nausea/vomiting were the most frequently reported grade 3 to 4 adverse events (AEs). The rates of grade 3/4 AEs and dose reduction were comparable between the 2 groups. There was no treatment discontinuation due to grade 3 to 4 AE. As a first-line treatment for patients with mGC, mDCX and mDCF regimens have comparable efficacy and tolerability profiles.

Comparative analysis of doublet chemotherapy regimens plus bevacizumab in patients with recurrent ovarian cancer.

Among all gynecological malignancies, ovarian cancer is the predominant cause of mortality. Hence, various chemotherapy protocols have been established for managing metastatic ovarian cancer cases. The present study aimed to assess and compare the efficacy of dual chemotherapy regimens plus bevacizumab in patients diagnosed with recurrent platinum-sensitive epithelial ovarian cancer. This was a retrospective observational study. Data on the clinical, pathological, radiological, and treatment characteristics of the patients were recorded. Survival analyses were performed using the Kaplan-Meier method. Moreover, multivariate Cox regression analysis was conducted. Data of a total of 198 patients with a median follow-up duration of 18.7 months after bevacizumab treatment were analyzed. Serous carcinoma was found to be the most common pathological subtype in the analyzed patients, accounting for 85.8% of all cases. In total, 46.5% (n = 92), 38.4% (n = 76) and 15.2% (n = 30) patients had received gemcitabine plus carboplatin, paclitaxel plus carboplatin (PC), and gemcitabine plus cisplatin combined with bevacizumab, respectively. The complete response rate was 18.7%, partial response rate was 56.1%, stable disease rate was 6.6%, and progressive disease rate was 18.7%. The patients received bevacizumab treatment at a median of 9 cycles and doublet chemotherapy at a median of 7 cycles. The median progression-free survival was 11.9 (95% CI: 9.2-14.5) months, and the median overall survival (OS) was 24.7 (95% CI: 19.9-29.4) months. The results showed that a history of surgery prior to bevacizumab treatment was a significant factor affecting OS (P = .006). Patients who had received gemcitabine plus carboplatin with bevacizumab (28 months) had significantly better OS than patients who had received paclitaxel plus carboplatin (20.1 months) and gemcitabine plus cisplatin (17 months) (P = .009). Doublet chemotherapy regimens plus bevacizumab are safe and effective against recurrent platinum-sensitive epithelial ovarian cancer. Gemcitabine plus carboplatin with bevacizumab was superior to other treatment regimens in terms of OS outcomes.

The safety and efficacy of first-line atezolizumab plus bevacizumab in patients with unresectable hepatocellular carcinoma: A multicenter real-world study from Turkey.

The aim of the study was to evaluate the real-world clinical outcomes of atezolizumab and bevacizumab (Atez/Bev) as the initial therapy for advanced hepatocellular carcinoma (HCC). We retrospectively analyzed 65 patients treated with Atez/Bev for advanced HCC from 22 institutions in Turkey between September 2020 and March 2023. Responses were evaluated by RECIST v1.1 criteria. The median progression-free survival (PFS) and overall survival (OS) were calculated using the Kaplan-Meier method. Cox regression model was employed to conduct multivariate analyses. The median age was 65 (range, 22-89) years, and 83.1% of the patients were male. A total of 1.5% achieved a complete response, 35.4% had a partial response, 36.9% had stable disease, and 26.2% had progressive disease. The disease control rate was 73.8% and associated with alpha-fetoprotein levels at diagnosis and concomitant antibiotic use. The incidence rates of any grade and grade ≥ 3 adverse events were 29.2% and 10.7%, respectively. At a median follow-up of 11.3 (3.4-33.3) months, the median PFS and OS were 5.1 (95% CI: 3-7.3) and 18.1 (95% CI: 6.2-29.9) months, respectively. In univariate analyses, ECOG-PS ≥ 1 (relative to 0), Child-Pugh class B (relative to A), neutrophil-to-lymphocyte ratio (NLR) > 2.9 (relative to ≤ 2.9), and concomitant antibiotic use significantly increased the overall risk of mortality. Multivariate analysis revealed that ECOG-PS ≥ 1 (HR: 2.69, P = .02), NLR > 2.9 (HR: 2.94, P = .017), and concomitant antibiotic use (HR: 4.18, P = .003) were independent predictors of OS. Atez/Bev is an effective and safe first-line therapy for advanced-stage HCC in a real-world setting. The survival benefit was especially promising in patients with a ECOG-PS score of 0, Child-Pugh class A, lower NLR, and patients who were not exposed to antibiotics during the treatment.

Efficacy of Capecitabine and Temozolomide Regimen in Neuroendocrine Tumors: Data From the Turkish Oncology Group.

INTRODUCTION: This study aims to report the efficacy and safety of capecitabine plus temozolomide (CAPTEM) across different lines of treatment in patients with metastatic neuroendocrine tumors (NETs). METHODS: We conducted a multicenter retrospective study analyzing the data of 308 patients with metastatic NETs treated with CAPTEM between 2010 and 2022 in 34 different hospitals across various regions of Turkey. RESULTS: The median follow-up time was 41.0 months (range: 1.7-212.1), and the median age was 53 years (range: 22-79). Our results across the entire patient cohort showed a median progression-free survival (PFS) of 10.6 months and a median overall survival (OS) of 60.4 months. First-line CAPTEM treatment appeared more effective, with a median PFS of 16.1 months and a median OS of 105.8 months (median PFS 16.1, 7.9, and 9.6 months in first-, second- and ≥third-line respectively, P = .01; with median OS values of 105.8, 47.2, and 24.1 months, respectively, P = .003) In terms of ORR, the first-line treatment again performed better, resulting in an ORR of 54.7% compared to 33.3% and 30.0% in the second and third or higher lines, respectively (P < .001). Grade 3-4 side effects occurred only in 22.5% of the patients, leading to a discontinuation rate of 9.5%. Despite the differences in outcomes based on treatment line, we did not observe a significant difference in terms of side effects between the first and subsequent lines of treatment. CONCLUSIONS AND RELEVANCE: The substantial superior outcomes in patients receiving first-line CAPTEM treatment highlight its potential as an effective treatment strategy for patients with metastatic NET.

Do Not Forget Afghanistan in Times of COVID-19: Telemedicine and the Internet of Things to Strengthen Planetary Health Systems.

Health care does not always take place in a setting of peace, prosperity, and social order, a point that is often overlooked in quotidian medical practice. This has become most evident with the current COVID-19 pandemic by the new coronavirus that is wreaking havoc across the planet. Health care providers are facing unprecedented challenges to intervene on numerous nonlinear uncertainties in science and society as the pandemic evolves. In Afghanistan, health care delivery is already a major crosscutting challenge. Although efforts to rebuild the health care systems in Afghanistan have been made (Acerra et al.), both acute and chronic illnesses remain as major medical and critical governance gaps to be remedied. In addition, health care facilities and medical equipment are not adequate in the country. There is a need for medical and scientific expertise to clinically and sociologically contextualize and interpret diagnostic tests as well as drugs and vaccines that will be deployed in the coming months as part of the planetary collective response to the COVID-19 pandemic. In a time of pandemic and facing a novel infectious pathogen, health care workers are in need of planetary scale consultation and support. Even creating a small consultation network using mobile applications might offer improved health outcomes. The Internet of Things and digital health ought to be considered in concert with telemedicine as part of an effective pandemic response.

Immunohistochemical expression of plasminogen activator inhibitor-1 in subcutaneous versus omental adipose tissue in patients after elective abdominal surgery

Plasminogen activator inhibitor-1 (PAI-1) is a biomarker of thrombosis. Adipose and vascular tissues are among the major sources of PAI-1 production. Previous studies indicated that fat deposits mediate increased cardiovascular risk among obese individuals. We investigated the immunohistochemical (IHC) expression of PAI-1 in adipose and vascular tissues from the omentum and the subcutaneous tissue. The pathology samples were selected from 37 random patients who underwent elective abdominal surgery between 2008-2009. PAI-1 expression was semi-quantitatively scored and compared between the groups. Significant differences were noted in the IHC expression of PAI-1 between the omental and the subcutaneous adipose tissues (1.1 ± 0.8 versus 0.8 ± 0.6, respectively (p=0.05)). Adipose tissue displayed higher IHC expression of PAI-1 compared to vascular wall tissue in both omentum and subcutaneous sections (1.1 ± 0.8 versus 0.5 ± 0.9 (p=0.004), and 0.8 ± 0.6 versus 0.4 ± 0.6 (p=0.003), respectively). In conclusion, our study compared PAI-1 expression in the omentum versus the subcutaneous tissue and adipose versus vascular tissues. IHC expression of PAI-1 level was significantly higher in the omental adipose tissue compared to the subcutaneous adipose tissue. Adipose tissue displayed significantly higher PAI-1 expression than vascular tissue. The study elucidates the biological differences of adipose and vascular tissue from subcutaneous versus omental sections.
