Tumor Clinicopathological Characteristics and their Prognostic Value in Mucinous Colorectal Carcinoma

Abstract

Aim: This study analyzed clinicopathological features of colorectal mucinous carcinoma and their prognostic values. Patients&method: This study enrolled 265 patients with mucinous colorectal cancer. Clinicopathological information and prognosis were reviewed retrospectively. Kaplan–Meier method, log- rank test and COX proportional hazard regression models were used. Results: In postoperative mucinous carcinoma patients (median age 56, 119 [44.9%] female), advanced tumor stage (odds ratio [OR]: 2.378; 95% CI: 1.512–3.741; p = 0.0002), poor differentiation (OR: 1.896; CI: 1.217–2.955; p = 0.0047) and right-sided tumors (OR: 2.421; CI: 1.145–5.102; p = 0.0206) were associated with shorter overall survival. Appendiceal/ileocecal cecal tumors were not different for prognosis. Conclusion: Mucinous colorectal carcinoma exhibits distinct tumor characteristics. Poor differentiation, advanced stage at presentation and the right side serve as negative prognostic factors.
