Prognostic factors of colostomy free survival in patients presenting with locally advanced anal canal carcinoma: A pooled analysis of two prospective trials (KANAL 2 and ACCORD 03).

CONCLUSION: Our study highlights new favorable prognostic factors such as circumferential tumor damage of less than two thirds, age over 55 years, dose escalation boost irradiation and possibly a total radiation dose between 60 and 65 Gy (but the BED dose depends on the overall treatment time). These results could be considered for better selection or stratification of the target population in future trials. PMID: 30172453 [PubMed - as supplied by publisher]
