Abstract

Background/aims: An organ preservation approach using chemoradiotherapy has been established for anal cancer. This retrospective cohort study aimed to define the clinico-demographic characteristics and outcomes of cases of human immunodeficiency virus (HIV)-negative anal carcinoma during a period of 20 years in a single comprehensive cancer institute.<br />Materials and Methods: This was a single-center retrospective cohort study of patients who were treated between January 1995 and January 2015. The primary outcome measures that were investigated included overall survival (OS), progression-free survival (PFS), colostomy rates, and colostomy-free survival (CFS).<br />Results: A total of 28 patients who were principally treated with standard 5-fluorouracil + mitomycin combination chemoradiotherapy were eligible for analysis. The 3- and 5-year PFS rates were 92.4% and 63%, respectively. The lower T stage was found to be associated with a prolonged PFS (p=0.001). The 3- and 5-year CFS rates were 84.3% and 74.9%, respectively. A longer CFS was observed with lower T stages (p=0.05). At the last follow-up, 75% of the patients with anal cancer were alive, and 71.4% of the patients were disease free. The median OS was not reached with a median follow-up of 54 months (range, 6-115 months). The 3- and 5-year OS rates were 82% and 71.1%, respectively. No late toxicity was observed during the follow-up period.<br />Discussion: The short- and long-term prognoses of HIV-negative patients with anal squamous cell carcinoma were good, and low-grade toxicity was rare, thereby demonstrating that these patients can be successfully treated in a real-life setting with favorable outcomes.
