Brief Summary:

RATIONALE: Photodynamic therapy uses light and drugs that make cancer cells more sensitive to light to kill tumor cells. Photodynamic therapy using aminolevulinic acid cream may be effective in treating patients with skin cancer.

PURPOSE: This randomized phase II trial is studying how well photodynamic therapy works in treating patients with skin cancer.

Condition or disease Intervention/treatment Phase
Non-melanomatous Skin Cancer Drug: aminolevulinic acid hydrochloride Procedure: conventional surgery Phase 2

Detailed Description:


  • Characterize the penetration of topically applied aminolevulinic acid (ALA) into the lesions of patients with primary basal cell and squamous cell carcinomas.
  • Quantitate the depth of fluorescence achievable with varying application periods of ALA in these patients.
  • Compare the results of tissue fluorescence with surface fluorescence measurements in these patients.

OUTLINE: This is a randomized study. Patients are stratified according to lesion type (superficial basal cell carcinoma (BCC) vs nodular BCC vs squamous cell carcinoma). Patients within each group are randomized to receive one of two application times: 4-5 or 20-24 hours in duration.

Aminolevulinic acid is topically applied either in a cream mixture or an alcohol base and an occlusive dressing placed over the lesion. After the randomized treatment duration has expired, the dressing is removed and quantitative protoporphyrin IX fluorescence measurements from the tumor and surrounding skin are mapped using a fluorometer. Routine surgical excision is then performed on the carcinoma.

Patients return after one to two weeks for a follow-up examination and suture removal.

PROJECTED ACCRUAL: 54 patients will be accrued within 10 years.
