Relation of cetuximab-induced skin toxicity and early tumor shrinkage in metastatic colorectal cancer patients: results of the randomized phase 3 trial FIRE-3 (AIO KRK0306)

摘要

Background: Cetuximab-induced skin toxicity (Cet-ST) is positively associated with outcome in metastatic colorectal cancer (mCRC). Besides its predictive relevance for targeted therapy, we investigated its prognostic impact with early tumor shrinkage (ETS) >= 20%, another on-treatment surrogate for clinical outcome in FIRE-3.
