Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

RATIONALE: Photodynamic therapy uses a drug, such as HPPH, that becomes active when it is exposed to a certain kind of light. When the drug is active, tumor cells are killed. This may be an effective treatment for laryngeal cancer. PURPOSE: This phase I trial is studying the side effects and best dose of laser light therapy when given together with HPPH in treating patients with dysplasia, cancer in situ, or invasive cancer of the larynx.
