ASTRO: Photodynamic Therapy Useful in Breast Cancer Patients That Have Reached Radiation Dose Limits NEW ORLEANS, LA -- October 10, 2002 -- Photodynamic therapy (PDT) appears to be safe and effective in breast cancer patients with chest wall progression who have received maximum cumulative radiation doses, while sparing painful fibrotic tissue changes. Dr. Ron Allison, chairman of the department of radiation oncology, with the Brody School of Medicine, in Greenville, North Carolina, United States, presented his findings October 9 at the American Society for Therapeutic Radiology and Oncology (ASTRO) 44th Annual Meeting. "Approximately 5 percent of breast cancer patients will experience a chest wall recurrence of cancer," said Dr. Allison. "PDT may be useful in such cases, but limited data exist about the efficacy of PDT in patients who have undergone maximal doses of radiation therapy."
