Brief Summary: This phase I trial is studying the side effects and best dose of photodynamic therapy with lutetium texaphyrin in treating patients with locally recurrent prostate cancer Photodynamic therapy uses light and drugs that make cancer cells more sensitive to light to kill tumor cells This may be effective treatment for locally recurrent prostate cancer Photosensitizing drugs such as lutetium texaphyrin are absorbed by cancer cells and when exposed to light become active and kill the cancer cells
Detailed Description: PRIMARY OBJECTIVES

I Determine the dose limiting toxicities and maximum tolerated dose of photodynamic therapy PDT using 730 nm light and lutetium texaphyrin in patients with locally recurrent prostate adenocarcinoma who have failed previous definitive radiotherapy

SECONDARY OBJECTIVES

I Measure lutetium texaphyrin levels in needle biopsies of the prostate before and after PDT using an HPLC and tissue fluorescence assay and calculate the percent change in lutetium texaphyrin after treatment

II Measure lutetium texaphyrin fluorescence in situ in the prostate before and after PDT using optical methods and correlate these results with the direct tissue measurements made in the biopsies of these patients

III Determine clinical outcome including clinical response progression free survival time to complete response time to biochemical relapse time to local progression time to distant failure overall survival and disease specific survival in these patients treated with this regimen

OUTLINE This is a dose-escalation study of lutetium texaphyrin and light fluence

Patients receive lutetium texaphyrin IV over 10-15 minutes 3-24 hours before photodynamic therapy PDT Optical fibers attached to a laser are inserted through a catheter into the prostate The laser delivers 730 nm light to the prostate until the specified fluence is delivered Patients undergo biopsy of the prostate and bladder before and after PDT Cohorts of 3-6 patients receive escalating doses of lutetium texaphyrin and light fluence until the maximum tolerated dose MTD is determined The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose limiting toxicity

Patients are followed at 2 weeks 1 month 2 months 3 months then every 3 months until 2 years then every 6 months for 3 years and then annually thereafter

PROJECTED ACCRUAL A minimum of 24 patients will be accrued for this study within 3 years
