Objective To summarize the research progress of colorectal mucinous adenocarcinoma.Method The articles about colorectal mucinous adenocarcinoma in recent years were reviewed.Results The colorectal mucinous adenocarcinoma was a pathological subtype of colorectal cancer, which had unique clinicopathologic characteristics, relatively low incidence, and poor prognosis. The current studies suggested that the BRAF mutation, microsatellite instability, CpG island methylation, and mucin expression were related to the occurrence and development of colorectal mucinous adenocarcinoma, but its molecular mechanism was still unclear. The colorectal mucinous adenocarcinoma was more common in the proximal colon and female patients. The multiple metastases, extrahepatic and peritoneal metastases were also common. The preoperative MRI examination was very valuable. The main treatment was surgery, and the multidisciplinary discussions were still needed to determine the best treatment for patients in the advanced stage. Compared with other types of colorectal adenocarcinoma, patients with colorectal mucinous adenocarcinoma had a poor prognosis.Conclusions Although we have a certain understanding of colorectal mucinous adenocarcinoma, the study results are limited due to the small sample size of many related articles and the lack of prospective randomized controlled studies. Therefore, more studies are needed in the future to improve the cognition of colorectal mucinous adenocarcinoma. Future research should focus on the molecular mechanism and treatment of colorectal mucinous adenocarcinoma.
