Brief summary
RATIONALE: Photodynamic therapy uses a drug that becomes active when it is exposed to a certain kind of light. When the drug is active, tumor cells are killed. PURPOSE: This randomized phase I trial is studying the side effects and best dose of photodynamic therapy in treating patients with premalignant or early stage head and neck tumors.
Detailed description
OBJECTIVES: Primary * To evaluate the toxicities associated with aminolevulinic acid-mediated photodynamic therapy when administered continuously or in fractionated doses in patients with premalignant or early stage head and neck lesions. Secondary * To assess the efficacy of this regimen in these patients. OUTLINE: This is a dose-escalation study of photodynamic therapy. Patients are randomized to 1 of 2 treatment arms. * Arm I: Patients receive oral aminolevulinic acid and then undergo continuous photodynamic therapy 4-6 hours later. * Arm II: Patients receive aminolevulinic acid as in arm I and then undergo fractionated photodynamic therapy 4-6 hours later. After completion of study therapy, patients are followed up at 1 month, every 3 months for 2 years, and then annually thereafter.
Interventions
Patients undergo continuous or fractionated photodynamic therapy.

Inclusion criteria
DISEASE CHARACTERISTICS: * Histologically confirmed diagnosis of 1 of the following within the past 3 months: * Erythroplakia with dysplasia * Severe dysplasia * Carcinoma in situ of the head and neck for which standard therapy is not indicated, according to any of the following: * Medical condition that precludes surgery * Lesions that cannot be completely resected based on size or location * Significant functional morbidity would be anticipated with further surgery * Refused standard therapy after the treatment has been discussed and offered * No invasive squamous cell carcinoma of the head and neck PATIENT CHARACTERISTICS: * ECOG performance status of 0-2 * Platelet count ≥ 100,000/mm\^3 * Total bilirubin ≤ 2 times upper limit of normal (ULN) * AST or ALT ≤ 2 times ULN * Alkaline phosphatase ≤ 2 times ULN * Not pregnant or nursing * Negative pregnancy test * Fertile patients must use effective contraception * No prior chronic liver disease or cirrhosis of the liver * No porphyria or hypersensitivity to porphyrins * No significant cardiovascular history that, in the opinion of a cardiologist, would deem the patient at risk for hypotension that may occur with oral administration of aminolevulinic acid (Levulan®) * No prior adverse reaction to ondansetron or lorazepam PRIOR CONCURRENT THERAPY: * Not specified
