- Abstract
Background: Anal cancer is a rare entity and the effect of gender and HPV status on survival is controversial. We aimed to evaluate the difference in overall survival (OS) according to gender and analyzed the effect of HPV status on OS. Patients and methods: The National Cancer Database (NCDB) was queried for patients with anal squamous cell carcinoma between 2004 and 2016. We evaluated the OS based on gender and HPV status using Kaplan-Meier estimates and we used multivariate Cox regression analyses to evaluate factors associated with overall survival. Results: A total of 6133 patients with known HPV status were included for analysis. In the non-metastatic group, male gender was associated with worse OS (HR 1.50, 95% CI 1.32–1.70; P<0.001) whereas HPV status did not affect the OS (HR 1.08, 95% CI 0.96–1.22; P=0.213). In the metastatic group, there was no difference in OS based on gender (HR 1.29, 95% CI 0.91–1.82; P=0.148), whereas HPV-negative status was associated with worse OS (HR 1.52, 95% CI 1.09–2.12; P=0.014). Conclusion: Females had better OS only in non-metastatic anal squamous cell carcinoma (ASCC). HPV-negative status was associated with worse OS only in metastatic ASCC.
