Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The investigators' data from a phase I study of short course radiation therapy followed by chemotherapy showed 74% complete clinical response (cCR). Given the promising response rate, the investigators are evaluating short course radiation therapy (SCRT) followed by chemotherapy in a multi-institution phase II trial to validate the cCR rate of this treatment paradigm. SCRT has not been prospectively evaluated in non-operative management for patients with non-metastatic rectal adenocarcinoma.
