Summary
This randomized phase II trial studies how well photodynamic therapy with HPPH works in
treating patients with squamous cell carcinoma of the oral cavity. Photodynamic therapy uses
HPPH that becomes active when it is exposed to a certain kind of light. When the drug is
active, cancer cells are killed. This may be effective against squamous cell carcinoma of the
oral cavity.
