Task: Question Answering
Input (English): Context: To assess the role of Notch activation in predicting bevacizumab efficacy in colorectal cancer (CRC).', 'Notch activation was evaluated by immunohistochemistry (IHC) on 65 CRC enrolled within randomized clinical trials assessing first-line bevacizumab-based chemotherapy and on 21 CRC treated with chemotherapy alone.', 'Strong Notch (IHC 3+) activation was negatively associated with response (18 vs 62% in low Notch cases [IHC 0, 1, 2+]; p = 0.016), progression-free survival (4.9 vs 12.1 months; p = 0.002) and overall survival (19.3 vs 30.4 months; p = 0.039). No correlation was found between Notch activation and clinical outcome in CRC treated with chemotherapy alone.\Question: Does strong Notch activation hinder bevacizumab efficacy in advanced colorectal cancer?
Output (English): A potential role of Notch activation in the antitumor activity of bevacizumab could be hypothesized.
