In general, the development of SCCA is commonly linked to a prior history of HPV. Unfortunately, HPV vaccination continues to be underutilized in the United States versus other countries. Increased acknowledgment of the importance of HPV vaccination as an anticancer vaccine should be encouraged. The present standard of care is primary chemoradiotherapy (CRT), which results in a high level of disease control for small, early-stage SCCA. More advanced cancers still fare poorly with this treatment, and the disease relapses locoregionally in the majority of cases (30%\u201350% of patients), resulting in an abdominoperineal resection. Current treatment recommendations are associated with substantial morbidity; alternative radiation doses and\/or novel combinations of agents with CRT are needed to improve quality of life and oncologic outcomes. Cytotoxic chemotherapy remains the standard of care for treatment-na\u00efve patients with metastatic disease, with a possible new treatment paradigm of carboplatin\/weekly paclitaxel. In addition, immune checkpoint inhibition appears to have a promising role in the setting of patients with refractory disease. Several clinical trials with immunotherapeutic and vaccine approaches for locally advanced and metastatic anal cancer are ongoing, as are HPV-agnostic umbrella trials. Whenever possible, clinical trial enrollment is always encouraged for further therapeutic development in the setting of a rare cancer, given the potentially substantial global impact for other HPV-associated malignancies.
