Abstract:
Background: Colorectal cancer (CRC) with mucinous component is associated with distinct characteristics and controversial prognosis. Patients & methods: A total of 1800 CRC patients were retrospectively enrolled and grouped by the mucinous content of the primary tumors. The clinicopathological characteristics and overall survival rate were compared between groups. Results: Mucinous adenocarcinoma (MAC) and adenocarcinoma with mucinous component (AMC) had higher frequencies of DNA mismatch repair protein deficiency, KRAS, BRAF and PIK3CA mutations as compared to those of conventional adenocarcinoma (CAC). MAC had worse prognosis than CAC. However, MAC was not an independent prognostic factor in multivariable analysis. Conclusion: Molecular features of AMC and MAC were similar, which were different from those of CAC. Neither MAC nor AMC were independent prognostic factors for CRC.
