    OBJECTIVE: Prostate cancer is among the most common cancers in males. Prostate cancer is androgen dependent in the beginning, but as time progresses, it becomes refractory to androgen deprivation treatment. At this stage, docetaxel has been used as standard treatment for years. Cabazitaxel has become the first chemotherapeutic agent which has been shown to increase survival for patients with metastatic Castrate Resistant Prostate Cancer (mCRPC) that progresses after docetaxel. Phase 3 TROPIC study demonstrated that cabazitaxel prolongs survival. PATIENTS AND METHODS: In this study, we evaluated a total of 103 patients who took cabaz-itaxel chemotherapy for mCRPC diagnosis in 21 centers of Turkey, retrospectively. This study included patients who progressed despite doc-etaxel treatments, had ECOG performance score between 0-2, and used cabazitaxel treatment. Patients received cabazitaxel 25 mg/m2 at every 3 weeks, and prednisolone 5 mg twice a day. RESULTS: Median number of cabazitaxel cures was 5.03 (range: 1-17). Cabazitaxel response evaluation detected that 34% of the patients had a partial response, 22.3% had stable disease and 32% had a progressive disease. Grade 3-4 hema-tological toxicities were neutropenia (28.2%), neutropenic fever (14.5%), anemia (6.7%), and thrombocytopenia (3.8%). In our study, median progression-free survival (PFS) was 7.7 months and overall survival (OS) was 10.6 months. CONCLUSIONS: This study reflects toxicity profile of Turkish patients as a Caucasian race. We suggest that cabazitaxel is a safe and effective treatment option for mCRPC patients who progress after docetaxel. Moreover, ethnicity may play important roles both in treatment response and in toxicity profile.

    The effect of the gastrectomy on survival in patients with metastatic gastric cancer: A study of ASMO
    (Future Medicine Ltd., 2016) Yazici O.; Özdemir N.; Duran A.O.; Menekşe S.; Nahit Şendur M.A.; Karaca H.; Göksel G.; Arpaci E.; Hacibekiroʇlu I.; Bilgetekin I.; Kaçan T.; Özkan M.; Aksoy S.; Aksoy A.; Çokmert S.; Uysal M.; Elkiran E.T.; Çiçin I.; Büyükberber S.; Zengin N.
    Aim: To investigate the role of surgical resection of primary tumor on overall survival (OS) in advanced gastric cancer patients at the time of diagnosis. Patients & methods: The survival rates of metastatic gastric cancer patients whose gastric primary tumor was resected at time of diagnosis were compared with metastatic gastric cancer patients whose primary tumor was nonresected. Results: The median progression-free survival and OS in operated and nonoperated group were 10 versus 6, 14 versus 9 months, respectively (p < 0.001). In multivariate analysis, gastric resection of primary tumor, Eastern Cooperative Oncology Group performance status, second-line chemotherapy had a significant effect on OS (hazard ratio [HR]: 0.52 [95% CI: 0.38-0.71], HR: 0.57 [95% CI: 0.42-0.78], HR: 1.48 [1.09-2.01]; p ≤ 0.001, p = 0.001 and p = 0.012, respectively). Conclusion: Subpopulations of patients with metastatic gastric cancer might benefit from surgical removal of primary tumor. © 2016 Future Medicine Ltd.
