摘要: The effect of NRAS mutations on the pathological features and clinical outcomes in patients with cutaneous melanoma was compared that tumors containing BRAF(V600E) wild type for both (WT). Clinical outcome data were obtained from a prospective cohort 249 patients. Mutations involving detected by PCR sequence verified. Cox proportional hazards regression performed to relate BRAF outcome. Seventy-five percentage occurred >1 mm thick (BRAF(V600E) 40%, WT 34%); 75% had mitosis/mm(2) 55%). When WT, multivariate analysis melanoma-specific survival (MSS) identified as an adverse prognostic factor [hazard ratio (HR) 2.96; P = 0.04] but not (HR 1.73; 0.23). associated thicker higher rates mitosis when independently this, shorter MSS.
