Purpose: Advanced gastric cancer (AGC) has a dismal prognosis. Platin-5-fluorouracil (CF) combination chemotherapy is the most widely used protocol and addition of a taxane (TCF) seems to increase survival and toxicity rates. We aimed to evaluate efficacy and toxicity of TCF as compared to CF in patients older than 65 years and compare them with the patients younger than 65 years. Methods: A total of 341 patients with AGC have been treated at six different oncology centers in Turkey between 2010 and 2014 and evaluated retrospectively. The characteristics of the patients whose tumors were histologically confirmed and whose survival data were available were registered and analyzed. The study group consisted of 234 patients younger than 65 years (group 1) and 107 patients older than 65 years (group 2). All of the data obtained from the patients were statistically analyzed. Results: The median age of the patients was 58.2 years and the mean follow-up time 14.4 months. For the entire group, progression-free survival (PFS) and overall survival OS) were 9 and 13 months, respectively. Using TCF over CF regimen increased the OS by 4.2 months (i.e., group 1 and 2 together). For group 2, patients with liver metastases and without surgery of the primary tumor were treated with significantly more TCF as compared to CF, respectively. Although TCF yielded significantly higher PFS and OS in group 1 (p=0.0001 and p=0.017), there was no significant difference in group 2 as compared to CF. Also, grade 3-4 toxicity was statistically defined as one of the possible reasons of worsened OS in patients older than 65 years and receiving TCF. Conclusions: The addition of taxanes to CF backbone leads to a significant increase in both PFS and OS in patients younger than 65 years of age but the triplet regimen with taxanes does not provide superior survival in patients older than 65 years of age.

Purpose In this study, we looked for whether treatment-induced rash predicts treatment efficacy in patients with recurrent/metastatic HNSCC treated with Cetuximab and chemotherapy. Methods Patients who were treated with platinum-based chemotherapy and cetuximab for the first line treatment of recurrent/metastatic HNSCC were recruited. Presence of rash, hypomagnesemia, hypopotassemia, anemia, neutropenia, thrombocytopenia during treatment and treatment response, date of progression, date of last visit and death were recorded. Results A total of 138 patients' data were available for analysis. Any grade of rash was detected in 57 (44.5%) of the patients. The incidence of rash was significantly higher in patients with objective response than in patients with disease progression (%56.8 vs %14.3, p < 0.001). Progression free survival was 7.06 months (4.98-9.15) in patients treated with cetuximab and chemotherapy as first line treatment. In the multivariate analysis; rash was significantly correlated with longer PFS (HR 2.136; 95% CI 1.067-4.278; p = 0.032). Progression free survival was 9.65 months in patients who experienced rash, and 6.02 months in patients without rash, (p = 0.019, log-rank test). Overall survival was 11.24 months (9.65-12.82). In multivariate analysis, the survival of patients with rash was significantly longer than patients without rash (HR 1.954; 95% CI 1.162-3.285; p = 0.012). Overall survival was 15.08 months in patients who experienced rash, and 8.61 months in patients without rash (p = 0.05, log-rank test). Conclusion Cetuximab-induced rash is associated with better ORR and longer PFS and OS in patients with recurrent/metastatic HNSCC treated with Cetuximab and platinum-based chemotherapy.

Objective Cisplatin-paclitaxel and bevacizumab is a frequently used treatment regimen for metastatic or recurrent cervical cancer, and carboplatin-paclitaxel and bevacizumab are also among the recommended regimens. In this study we aimed to evaluate the efficacy of these two regimens for the treatment of metastatic or recurrent cervical cancer. Methods Patients with metastatic or recurrent cervical cancer treated with cisplatin-paclitaxel and bevacizumab or carboplatin-paclitaxel and bevacizumab were retrospectively evaluated in this study. The clinical and demographic characteristics of patients in each group were evaluated. Median overall survival, progression-free survival, and response rates between the two groups were compared. Results A total of 250 patients were included. Overall, the numbers of patients with recurrent disease and metastatic disease were 159 and 91, respectively. The most common histologic subtype was squamous cell carcinoma (83.2%). The median duration of follow-up was 13.6 (range 0.5-86) months. The median progression-free survival was 10.5 (95% CI 9.0 to 11.8) months in the cisplatin-paclitaxel and bevacizumab group (group 1), and 10.8 (95% CI 8.6 to 13.0) months in the carboplatin-paclitaxel and bevacizumab group (group 2) (HR 1.20; 95% CI 0.88 to 1.63; p=0.25). The median overall survival was 19.1 (95% CI 13.0 to 25.1) months in group 1 and 18.3 (95% CI 15.3 to 21.3) months in group 2 (HR 1.28; 95% CI 0.91 to 1.80; p=0.15). Conclusions There is no survival difference between cisplatin or carboplatin combined with paclitaxel and bevacizumab in metastatic or recurrent cervical cancer.
