Abstract
Fourteen women with locally recurrent breast carcinoma on the chest wall following mastectomy were given 30 courses of photodynamic therapy (PDT). All patients had been heavily pretreated with conventional modes of therapy (radiation therapy, chemotherapy, hormonal therapy, surgical resection). Twenty-two courses yielded a partial response; two courses yielded a complete response; four courses showed no response; one patient was treated as an adjunct to surgery; and one patient was lost to follow-up. Duration to response was variable, ranging from 6 weeks to 8 months. Several women had chest wall disease controlled for prolonged periods of time using repeated courses of PDT. Two women had re-epithelialization of ulcerated lesions. Complications were minimal and included pain (two patients), sunburn (two), and infection (one). These results suggest that treatment with PDT can aid in local control of chest wall recurrence following mastectomy in selected patients.
