[Perioperative targeting brachytherapy for lung cancer invading the chest wall].
We evaluated the efficacy of perioperative targeting brachytherapy for lung cancer invading the chest wall. Between 1998 and 2003, 7 patients underwent perioperative targeting brachytherapy for lung cancer invading the chest wall. There were 5 male and 2 female patients. The mean age was 63.3 years, with a range of 45 to 77 years. All patients underwent complete resection including the chest wall combined resection. During the operation, plastic afterloading catheters fixed on the Vicryl mesh at interval of 1 cm were placed on the site of chest wall resection. From the third to sixth day after the operation, 15 to 32 Gy of radiation was delivered over 3 or 4 days using a high dose rate remote afterloading system. The area targeted for brachytherapy was determined by a computed tomography (CT) scanner translator with a computer program for radiation planning. The median postoperative hospital stay was 35 days. Local recurrences were observed in 2 patients, but there was no evidence of recurrence in the margin of the resected chest wall. We believe that this short period of treatment and the low side effects enhances the quality of the patients. Prevention of local recurrence was achieved in short term follow-up.
