This trial is for people aged twenty-two or older with HPV-associated tongue-base, tonsil, or unknown-primary cancer, stage I–III excluding N3. Detectable HPV16 tumor DNA in blood and planned nonsurgical treatment are required.

The idea: tumor stage, smoking history, and HPV blood tests guide radiation intensity. Lower-risk patients receive reduced radiation over five to six weeks; higher-risk patients receive standard doses over seven to eight weeks. Chemotherapy is selected when appropriate. Researchers measure two-year progression-free survival.

This phase 2 study plans 145 patients. Jonathan Schoenfeld leads at Dana-Farber; two Boston sites recruit.
