ABSTRACT
The incidence of anal cancer in the United States has increased in recent years, primarily related to the increasing incidence of HPV-associated anal squamous cell carcinoma, which is estimated to represent 80%-95% of anal cancers. Similar to head and neck cancer, HPV association has been demonstrated to be a strong positive prognostic factor in patients with anal cancer. Encouraging results from a number of studies investigating treatment de-escalation for HPV-associated oropharyngeal cancer support the notion that similar attempts may be feasible in HPV-associated anal cancer; however, the data to support this hypothesis are currently lacking. Studies are needed to determine how, if at all, HPV status should impact the management of patients with anal cancer. This review summarizes the relationship between HPV association and outcomes for patients with anal cancer, and how HPV status may impact the treatment of patients with anal cancer going forward.
