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. Photodynamic therapy using silicon phthalocyanine 4 may be effective against skin cancer.

PURPOSE: This phase I trial is studying the side effects and best dose of photodynamic therapy using silicon phthalocyanine 4 in treating participants with actinic keratosis, Bowen's disease, skin cancer, or stage I or stage II mycosis fungoides.

Detailed Description

OBJECTIVES:

* Determine the maximum tolerated dose of photodynamic therapy using topically delivered silicon phthalocyanine 4 in participants with actinic keratosis, Bowen's disease, squamous cell or basal cell skin cancer, or stage IA, IB, IIA, or IIB mycosis fungoides.

* Determine the safety and toxicity of this therapy with emphasis on whether it induces photosensitivity in non-treated sites in these participants .

* Determine the antitumor mechanism of this therapy, by monitoring tissue changes via clinical, histological, immunohistochemical, and other biochemical markers, in these participants.

* Determine, preliminarily, the dose of this therapy that results in highest clearing rates in these participants.

OUTLINE: This is a dose-escalation study.

Participants receive topical silicon phthalocyanine 4 (Pc 4). One hour later, participants undergo photodynamic therapy. Treatment repeats weekly for up to 3 weeks (up to 3 total treatments for the same lesion OR up to 3 lesions treated if multiple lesions are present).

Cohorts of 3 participants receive escalating doses of Pc 4 and visible light until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 1 of 3 participants experiences dose-limiting toxicity. Three additional participants are treated at the MTD.

After completion of study therapy, participants are followed for up to 2 weeks.

PROJECTED ACCRUAL: A total of 16-45 participants will be accrued for this study.
