Locational distributions of adenomas and cancers with K-ras/BRAF mutation and/or RASSF2 methylation. Cancers with K-ras/BRAF mutation and/or RASSF2 methylation exhibit locational distribution similar to that of adenomas. However, the proportion of tumours in the proximal colon with both K-ras/BRAF mutation and RASSF2 methylation was significantly higher in cancers (58%) than in adenomas (27%) (P=0.02). Arrowheads indicate serrated adenomas.
