Last-Resort prostate cancer therapy uses Light-Activated drug

This is a single-patient program for someone with advanced prostate cancer who has run out of standard treatments. The experimental therapy, X-PACT, combines a drug called methoxsalen with a special device that activates it using X-rays, injected directly into the tumor. The goal is to shrink the tumor and possibly trigger the immune system to fight the cancer. Because this is a last-resort option for one person, results may not apply to others.
