Impact of early tumor shrinkage and depth of response on the outcomes of panitumumab-based maintenance in patients with RAS wild-type metastatic colorectal cancer
European Journal of Cancer(2021)
摘要
•In Valentino trial, early tumor shrinkage/depth of response (ETS/DoR) is prognostic.•Poorest outcomes seen if no ETS/poor DoR + single-agent panitumumab maintenance.•Poorest outcomes seen if no ETS/poor DoR + resistance alterations beyond RAS/BRAF.•Tumor dynamics may be integrated in clinical trials or clinical decision-making.
