摘要: Purpose: The purpose of this study was to examine the prognostic and oxaliplatin predictive value mismatch repair (MMR) status common hot spot mutations, which we previously identified in stage II III colon cancer. Experimental Design: Mutations BRAF , KRAS NRAS MET PIK3CA were profiled 2,299 tumors from National Surgical Adjuvant Breast Bowel Project (NSABP) clinical trials C-07 ( n = 1,836) C-08 463) with Type Plex chemistry mass spectrometry. tested worth adding 5-fluorouracil plus leucovorin, bevacizumab FOLFOX. Cox proportional hazard models used assess or mutations for tumor recurrence, overall survival (OS), after recurrence (SAR). Results: associated MMR-deficient P ≤ 0.0002], poor SAR (HR, 2.31; 95% CI, 1.83–2.95; not OS, SAR. an improved prognosis based on 0.48; 0.33–0.70; Conclusions: This shows that cancer validates explains, at least part, previous observations associating it OS. Profiling all these is warranted future testing new targeted therapies block relevant signaling pathways. Such are under development NSABP. Clin Cancer Res; 18(23); 6531–41. ©2012 AACR .
