KRAS and mucinous adenocarcinoma: Although mvE cells were not associated with genomic status (microsatellite stable (MSS), microsatellite instability (MSI)-low, and MSI-high) (Figure S4) and mutation of BRAF, KRAS, and NRAS genes (Figure S5), mvE cells in mucinous adenocarcinoma were significantly higher than in adenocarcinoma (Figure S6).
