Trends in utilization of first-line palliative treatments for anal squamous cell carcinoma.

First-line use of palliative treatments to control symptoms is needed in a small proportion of anal squamous cell cancer patients. It was utilized in all stages, but it was most frequently observed in patients with stage IV disease and patients with <6 months life expectancy. First-line palliative therapy was also more frequent in lower-income patients and patients with Medicare and Medicaid insurance which highlights the disparities in anal cancer management.
