Popis: | The optimal timing of switching from platinum-based chemotherapy to pembrolizumab in patients with advanced urothelial carcinoma (UC) remains unclear.Thirty-four patients who received pembrolizumab as second-line treatment after first-line platinum-based chemotherapy were retrospectively evaluated.According to overall survival (OS) from pembrolizumab, there was a significant difference between ≤4 and4 prior chemotherapy cycles (7.0 and 25.5 months, p=0.034), but not between ≤6 and6 cycles (11.3 and 6.6 months, p=0.658). According to the Cox proportional hazards regression model, the number of chemotherapy cycles was not correlated with better OS in pembrolizumab-treated patients. According to the OS from the first-line treatment, there was a significant difference between ≤4 and4 prior chemotherapy cycles (17.3 and 37.1 months, p0.001), but not between ≤6 and6 cycles (18.6 and 27.3 months, p=0.276).The optimal timing of switching from platinum-base chemotherapy to pembrolizumab in advanced UC is around six cycles. |
