Real World Survival Data of A Rare Malignancy: Anal Cancer Results in Hiv Negative Patients From Turkey
Background/Aims: An organ preservation approach using chemoradiotherapy has been established for anal cancer. This retrospective cohort study aimed to define the clinico-demographic characteristics and outcomes of cases of human immunodeficiency virus (HIV)-negative anal carcinoma during a period of 20 years in a single comprehensive cancer institute. Materials and Methods: This was a single-center retrospective cohort study of patients who were treated between January 1995 and January 2015. The primary outcome measures that were investigated included overall survival (OS), progression-free survival (PFS), colostomy rates, and colostomy-free survival (CFS). Results: A total of 28 patients who were principally treated with standard 5-fluorouracil + mitomycin combination chemoradiotherapy were eligible for analysis. The 3- and 5-year PFS rates were 92.4% and 63%, respectively. The lower T stage was found to be associated with a prolonged PFS (p=0.001). The 3- and 5-year CFS rates were 84.3% and 74.9%, respectively. A longer CFS was observed with lower T stages (p=0.05). At the last follow-up, 75% of the patients with anal cancer were alive, and 71.4% of the patients were disease free. The median OS was not reached with a median follow-up of 54 months (range, 6-115 months). The 3- and 5-year OS rates were 82% and 71.1%, respectively. No late toxicity was observed during the follow-up period. Discussion: The short- and long-term prognoses of HIV-negative patients with anal squamous cell carcinoma were good, and low-grade toxicity was rare, thereby demonstrating that these patients can be successfully treated in a real-life setting with favorable outcomes.Wo
A phase II Study of weekly irinotecan in patients with metastatic colorectal cancer refractory to 5 FU based chemotherapy
A national, multicenter, non-interventional, observational study on treatment patterns in patients with metastatic renal cell carcinoma in Turkey - NOTES study
Introduction: The introduction of targeted therapies in renal cell carcinoma has significantly improved its prognosis and treatment outcomes in recent years. Such treatment options are targeted therapies of the vascular endothelial growth factor (VEGF) pathway and the mammalian target of the rapamycin pathway. With the use of tyrosine kinase inhibitors (TKIs) and mammalian target of the rapamycin inhibitors, overall survival has increased up to 2 years. In Turkey, due to applicable reimbursement conditions for patients with metastatic renal cell carcinoma (mRCC), interferon use is mandated as a first-line treatment, thus providing information on the use of everolimus only after initial interferon and second-line VEGF-targeted treatments such as VEGF-TKI

Safety and efficacy of trifluridine/tipiracil in previously treated metastatic colorectal cancer: PRECONNECT Turkey
Background: The efficacy and safety of trifluridine/tipiracil (FTD/TPI) for third-line treatment of metastatic colorectal cancer have been demonstrated. The authors present the Turkish post hoc analysis of the PRECONNECT study. Methods: An international, multicenter, single-arm, open-label, phase IIIb trial evaluating FTD/TPI in patients with >= 2 previous lines of chemotherapy for metastatic colorectal cancer was conducted. The primary end point was safety. Results: In this Turkish cohort (n = 100; eight centers), the most frequent treatment-emergent adverse event was neutropenia (48%). Median progression-free survival was 3.0 months; disease control rate was 36%; quality of life remained stable. Conclusion: Outcomes with FTD/TPI in Turkey are consistent with previous studies and confirm the efficacy and safety of FTD/TPI treatment in the third-line setting
Safety and efficacy of regorafenib in patients with treatment-refractory metastatic colorectal cancer in Turkey: the single-arm, open-label REGARD study
Objectives Regorafenib improved overall survival in patients with metastatic colorectal cancer (mCRC) refractory to standard therapies in two randomised, phase III trials, but has not been evaluated in Turkey. REGARD evaluated the safety and efficacy of regorafenib in Turkish patients with treatment-refractory mCRC
Quality of life study of patients with unresectable locally advanced or metastatic pancreatic adenocarcinoma treated with gemcitabine plus nab-paclitaxel versus gemcitabine alone: AX-PANC-SY001, a randomized phase-2 study
BackgroundCombination of gemcitabine and nab-paclitaxel has superior clinical efficacy than gemcitabine alone. Nevertheless, health-related quality of life. (QoL) associated with this combination therapy when administered at first-line in advanced pancreatic adenocarcinoma is unknown.MethodsA total of 125 patients were randomized to combination therapy (1000mg/m2 gemcitabine +125mg/m2 nab-paclitaxel) and single-agent gemcitabine (1000mg/m2) arms to take treatment weekly for 7 of 8weeks, and following 3 of 4weeks, until progression or severe toxicity. Primary endpoints were three-months of definitive deterioration free percent of patients, and QoL.ResultsOverall QoL analyses showed that 34 and 58.3% of cases in gemcitabine and gemcitabine+nab-P arms had no deterioration in 3rd month QoL scores (p=0.018). These proportions were 27.3 and 36.6% in 6(th) month assessments, respectively (p=0.357). Median overall survivals in combination and single-agent arms were 9.92months and 5.95months, respectively (HR: 0.64, 95% CI: 0.42-0.86, p=0.038). Median progression free survivals in these treatment arms were 6.28 and 3.22months, respectively (HR: 0.58, 95% CI: 0.39-0.87, p=0.008). Median time-to-deterioration were 5.36 vs 3.68months, and objective response rates were 37.1% vs 23.7% (p=0.009), respectively in combination and single-agent arms.ConclusionsCombination therapy with gemcitabine + nab-paclitaxel had better overall and progression-free survival than gemcitabine alone. Also, combination therapy showed increased response rate without toxicity or deteriorated QoL. Combination treatment with gemcitabine and nab-paclitaxel may provide significant benefit for advanced pancreatic cancer.Trial registrationThis study has been registered in ClinicalTrials.gov as NCT03807999 on January 8, 2019 (retrospectively registered)
