There is no tubular adenocarcinoma of the colon in the classification of colon cancer, which should be tubular adenoma of the colon.
Common treatments for colonic tubular adenoma include surgical resection and clinical observation and follow-up, depending on the condition.
Adenomas such as colonic tubular adenomas, villous adenomas, hereditary polyposis, inflammatory bowel disease-related intraepithelial neoplasia, aberrant crypt foci, and especially those associated with heterogeneous hyperplasia, are all considered as precancerous lesions. The principle of treatment for precancerous lesions such as colonic tubular adenoma is to remove the adenoma as soon as possible and pay attention to the follow-up.
At present, there is no clear clinical evidence on the cancer rate and prognosis of lesions with a diameter of less than 5 mm, so bulging and superficial bulging adenomas with a diameter of less than 5 mm may not require active treatment, and regular follow-up is sufficient.
However, for superficial depressed lesions, even if their diameter is within 5 mm, there is still a certain rate of carcinoma and submucosal infiltration, and it is generally believed that surgical resection of adenomas can significantly reduce the probability of colorectal cancer, and they should be resected. Most colonic adenomas are benign tumors and can be cured by endoscopic resection.
Prompt hospitalization is recommended for suspected colonic tubular adenomas.
