The cure rate and prognosis of mucinous adenocarcinoma of the colon are not yet uniform, and some foreign literature reports that the 5-year survival rate, or clinical cure rate, of mucinous adenocarcinoma is about 40%, while some small samples of domestic data suggest that the 5-year survival rate is about 20-30%. The cure rate may be related to the patient’s tumor site and tumor stage.
There are no authoritative data on mucinous adenocarcinoma of the colon because there are no large samples or multicenter data, and the inclusion criteria and diagnostic criteria are not uniform. However, because mucinous adenocarcinoma of the colon tends to grow infiltratively into surrounding tissues and is prone to distant metastases, it is usually detected at a later stage, so the overall cure rate is poor compared with that of nonmucinous adenocarcinoma. Radical resection and standardized radiotherapy are the primary modalities to improve survival.
Statistics show that mucinous adenocarcinoma of the colon also has a higher recurrence rate than non-mucinous adenocarcinoma, and some patients with mucinous adenocarcinoma of the colon are more often associated with malignancies of other organs. For example, stomach cancer, bile duct cancer, cervical cancer, prostate cancer and so on. Therefore, it is recommended that patients with mucinous adenocarcinoma of the colon should have relevant tests to exclude malignant tumors of other organs and be actively followed up.
