[Treatment of cancer in tubular villous colorectal adenomas].

OBJECTIVE

To study the results of treatment of cancer in tubular villous colorectal adenomas.

MATERIAL AND

METHODS

A retrospective analysis included 51 patients with cancer in tubular villous colorectal adenomas cTis-T1N0M0 between 02.2019 and 09.2021. The median age of patients was 64 (57; 71) years. Minimally invasive interventions were performed in all patients (transanal endoscopic microsurgical resection of the rectum - 25 cases, endoscopic submucosal dissection - 20 cases, laparoscopic resection of the intestine - 6 cases).

RESULTS

Intraoperative complications (intestinal wall perforation) developed in 1 (2%) patient, early postoperative complications (intestinal bleeding from suture line) - in 2 (4%) patients. Throughout the follow-up period (29-84 months), tumor recurrence was detected in 2 (4%) patients with rectal primary tumor, colorectal polyps - in 8 (15.7%) patients. Eleven (21.6%) patients had previous malignant tumors.

CONCLUSION

The study demonstrated favorable oncological and surgical results of treatment of cancer in tubular villous colorectal adenomas. Minimally invasive interventions are safe and predictable, as well as accompanied by low incidence of complications.
