To investigate the clinical and prognostic aspects of anal cancers associated with the presence, as well as the genotypic distribution of human papillomavirus HPV. The data analysis was done using descriptive univariate statistics, and the survival curves were made using the Kaplan—Meier and log-rank methods. Female patients had a higher prevalence of HPV. Multiple infections were detected in The most prevalent genotypes were HPVs 16, 33, and The overall survival at 60 months was
MATERIALS AND METHODS
Cases diagnosed between and from 39 population-based cancer registries were analyzed. Incidence rates were age-adjusted to the US standard population. From through , the annual age-adjusted invasive anal cancer incidence rate was 1. Squamous cell carcinoma SCC was the most common histology overall, accounting for 18, of 21, Women had a higher rate of SCC 1. Whites and blacks had the highest incidence rate 1. Incidence rates of anal SCC increased 2. The majority of SCC cases were diagnosed at the in situ or localized stage
A risk factor is anything that increases your chance of getting a disease such as cancer. Different cancers have different risk factors. Some risk factors, like smoking or diet, can be changed. Several factors can affect your risk of anal cancer. But having a risk factor, or even several risk factors, does not mean that you will get cancer.
