Watchful Waiting for Complete Responders to Therapy in Rectal Cancer

Rectal Cancer Clinical Trial

Official title: Treatment of T2-T3/NO-N+ Adenocarcinoma of the Rectum by Neoadjuvant Chemotherapy (FOLFOX) Followed by Preoperative Chemo (Fluorouracil / Capecitabine)-Radio Therapy (CRT) With Watchful Waiting for Complete Responders

Status Recruiting

Clinical Trial Summary

The purpose of this project is to determine if in a selected group of patients, at higher risk of wound dehiscence and other complications, treatment by local excision and management by a "watchful waiting" or an initial "non-operative management" approach, with an offer of radical resection only to those patients whose tumors demonstrate "regrowth" will maintain acceptable local control and overall survival rate for the whole cohort.

Clinical Trial Description

This is a prospective registration study of a very limited number of subjects (3-8/year) who have achieved full or near full clinical CR after neo-adjuvant FOLFOX chemotherapy prior to chemo-radiotherapy, but without subsequent surgery, to determine whether a "wait and see" approach will maintain local control while improving quality of life. Patients will undergo standard of care baseline work-up for their disease before being enrolled to the protocol followed by protocol treatment, all standard of care just in reverse order. Patients with less than 1/2 of the rectum being circumferentially involved at diagnosis will also receive additional brachytherapy which will be supported by hospital funded research dollars. Patients will undergo additional testing for study related purposes during the restaging processes such as MRI, endoscopic ultrasound, and will complete an assessment to determine impact on quality of life. Providers that will be conducting the MRI and endoscopic ultrasound have agreed to waive professional fees, as well as the hospital has agreed to waive facility fees that have been incurred while the patient is on study protocol. Patients will follow standard of care guidelines for follow up post-excision if they do not respond to treatment, and modified standard of care guidelines if their are identified as complete responders which will include additional imaging at specific milestones, again waived by providers and facility. Patients on watchful waiting, who recur locally will undergo total mesorectal excision. Patients will not be responsible for any fee incurred that is not considered standard of care.

Patients will be accrued as they present to the Van Elslander and Webber cancer center clinics. They will be enrolled in this arm of the study only if surgical evaluation indicates that surgical resection will extend to include the dentate line if said patients were candidates for local excision. We expect that about 3 patients/year will be eligible. ;
