Trial Outcomes & Findings for Radiochemotherapy With Panitumumab in the Localised Epidermoid Carcinoma of the Anus (NCT NCT01581840)

NCT ID: NCT01581840

Last Updated: 2024-07-01

Results Overview

Complete response was defined by the complete disappearance of the tumor on proctological examination and morphological examinations (MRI and/or echo-endoscopy) and the absence of secondary lesion appearance. The responses were validated by an independent committee: * In the event of a discrepancy between the investigator and the independent committee, the independent committee's response was used; * in case of uncertainty of the investigator on the response, the committee decided on the response in view of the clinical and morphological data; This endpoint was assessed 8 weeks after the end of treatment (week 15). A patient who died (regardless of cause) was considered a failure for the primary endpoint

SECONDARY outcome

Timeframe: At 3 years after inclusion

It was defined as the time from inclusion to the date of colostomy or death (from any cause). Patients alive without colostomy were censored at date of last news. If a patient had a shunt colostomy and continuity wasrestored, the patient was counted among the patients without a colostomy.
