Abstract

Objective: To review some histopathological characteristics of colorectal carcinoma at Hai Duong Provincial General Hospital in 2023. Subjects and research methods: cross-sectional description, combining prospective and retrospective studies, convenient sampling. Results: The average age of the study group was 69.3 ± 13.1. The female/male ratio was 1.1/1. Common adenocarcinoma accounted for the highest rate of 56.2%, followed by mucinous adenocarcinoma at 20.4%. Under the special histological type, adenocarcinoma had a low rate, less than 1%. There were no cases of clear cell carcinoma, squamous cell carcinoma, signet ring cell carcinoma and medullary body. Most colorectal cancers had invaded through the muscle layer to the subserosa equivalent to T3 (accounting for 70.8%); there were no tumors that only invaded the submucosa equivalent to T1. A total of 131/137 cases were histologically staged; most were from stage II to stage III (accounting for a total of 72.5%). Only 6.1% of cases were staged at stage IV. The proportions of cancer patients with vascular invasion, nerve invasion, lymphoplasmacytic invasion, and tumor necrosis were: 35%, 9.5%, 33.6%, and 49.6%, respectively. Conclusion: In colorectal cancer, the common adenocarcinoma type accounted for the highest proportion at 56.2%. Notably, there were no cases of signet ring cell adenocarcinoma, medullary adenocarcinoma, squamous adenocarcinoma, or clear cell adenocarcinoma. The new histological type of adenomatous adenocarcinoma accounted for 0.7%.
