简要总结
RATIONALE: Photodynamic therapy uses a drug, such as HPPH, that is absorbed by tumor cells. The drug becomes active when it is exposed to light. When the drug is active, tumor cells are killed.
PURPOSE: This phase I trial is studying the side effects and best dose of photodynamic therapy using HPPH in treating patients with recurrent dysplasia, carcinoma in situ, or stage I oral cavity cancer.
详细描述
OBJECTIVES:
Primary
- To determine the maximum tolerated dose in the oral cavity of photodynamic therapy (PDT) using HPPH and 665 nm light in patients with recurrent dysplasia, carcinoma in situ, or stage I squamous cell carcinoma of the oral cavity.
Secondary
- To determine response of dysplasia, carcinoma in situ, and selected patients with T1 squamous cell carcinoma of the oral cavity using PDT with HPPH and 665 nm light.

研究组 & 干预措施
Treatment (PDT)
Patients undergo PDT comprising HPPH IV over 1 hour on day 1 followed by laser light treatment to the tumor bed on day 2. Treatment may repeat every 8 weeks for up to 3 courses in the absence of disease progression or unacceptable toxicity.
干预措施: HPPH (Drug)
