TI  - V600E and Non-V600E BRAF Mutations  in Colorectal Cancer: Clinicopathologic  Correlations in a Single Institution
AB  - Genomic characterization of BRAF mutation in colorectal cancer (CRC) revolutionized it’s management. Current knowledge regard ing BRAF mutant CRC is based on the prevalent V600E mutation and mostly on Western population. However, CRC is known to be  a complex and heterogenous disease. Thus, we aim to characterize the molecular, clinical and epidemiologic features of V600E as  well as non-V600E BRAF mutated CRC in Turkish population. Demographic, histopathologic, molecular and clinical data of V600E  and non-V600E BRAF mutant, metastatic and non-metastatic CRC cases were retrospectively collected from a tertiary Oncology  hospital. Thirty cases of BRAF mutant colorectal carcinoma was identified. BRAF mutations were V600E (66.7%), V600A (10.0%),  V600G (3.3%), V600K (3.3%), and L597V (16.7%). BRAF V600E cases had similar characteristics with Western population: frequent  in females (45.0%), more proximal location (52.6%), aggressive histopathologic features (LVI 50.0%), and a worse prognosis (OS 13  vs 30 months, p= 0.068). Non-V600E BRAF mutant cases were diferred from V600E cases by being more frequent in males (50.0%),  located more distally (60.0%), and carrying a better prognosis. This study demonstrates V600E mutation in CRC in Turkey is similar  with Western population. In like manner, non-V600E BRAF mutation in CRC bears the potential to be a significant attribute for both  prognostic and therapeutic implications as well.
