Abstract:
In patient treated by mastectomy for breast cancer, chest wall and skin recurrences are frequently encountered. Chest wall recurrence results in profound physical and psychological morbidity, and often heralds the appearance of other, more life threatening metastasis. Traditionally the two most common treatments have been site-specific radiation and resection. Photodynamic therapy (PDT) provided an alternative treatment modality using a photosensitizer and laser light to induce selective tumor necrosis. The patient was 64- years old female, had undergone breast conserving surgery for cancer of the right breast. Chest wall and skin metastasis recurred at 40 months after the adjuvant treatment of chemotherapy. The lesions were progressed despite 2nd, 3rd chemotherapy and hyperthermal therapy. The light was administered through a diode laser turned to 630 nm wave length (150 J/cm2 in light dosage, 200 mW/cm2 in intensity), 72 h after photosensitizing agent injection. There was clinical evidence of partial response, defined as granulation tissue with re-epitheliaization from the periphery of normal epithelium. PDT has demonstrated good results in other solid tumors at some hospitals, however there has been no application for breast cancer in Korea previously. Our experience suggests that PDT is non-invasive procedure that is highly tolerable, particularly when compared with other modalities, and an effective treatment method for chest wall or skin recurrence that shows no response to other treatments.
