ABSTRACT

Purpose To investigate the clinicopathological features and prognosis in patients with colorectal cribriform comedo-type ad-enocarcinoma. Methods Compared with 278 cases of colorectal common-type adenocarcinoma, 24 cases of colorectal cribriform come-do-type adenocarcinoma were analyzed for clinical stage, lymphovascular invasion, lymph node metastasis and genetic characteristics. Results The percentage of clinical Ⅲ and Ⅳ (87. 5%) and lymph node metastasis rate (87. 5%) in patients with colorectal cribri-form comedo-type adenocarcinoma was obviously higher than that in colorectal common-type adenocarcinoma (42. 4%,42. 4%) (P0. 05 ) . Conclusions There is a higher clinical stage and poorer prognosis including unique morphological characteristics, highly lymphovascular invasion and lymph node metastasis in pa-tients with colorectal cribriform comedo-type adenocarcinoma.
