Avastin for bladder cancer – pro

Several studies of Avastin incombinations are ongoing but none employing irinotecan and Avastin. Bevacizumab was associated with significant toxicity, including venous thromboembolic events, in the first-line treatment of metastatic urothelial carcinoma in the phase II Hoosier Oncology Group GU04-75 trial presented at ASCO 2009. Among 43 patients receiving cisplatin, gemcitabine (Gemzar), and bevacizumab (Avastin), 60% required at least one dose modification and 42% discontinued therapy because of toxicity, including 21% who stopped bevacizumab due to deep vein thrombosis (DVT) or pulmonary embolism. However, there was an improvemetn in survival although strangely not in progressoin free survival.
