PURPOSE: To assess the feasibility and outcomes of (125)I Vicryl mesh brachytherapy after sublobar resection in stage I non small cell lung cancer (NSCLC) patients with poor pulmonary function. METHODS AND MATERIALS: Between January 1997 and July 2004, patients with poor cardiopulmonary reserve who had stage IA and IB (T1-2 N0 M0) NSCLC and a forced expiratory volume in 1s (FEV(1)) of > micro=0.6L were considered for limited surgical resection either by an open or video-assisted thoracoscopic procedure and for a subsequent (125)I Vicryl mesh brachytherapy implant. Mediastinal and hilar lymph node staging was performed routinely in all patients. After clear margins were obtained grossly and on frozen section, a single-plane (125)I implant was designed to encompass a plane consisting of the staple line and a 2-cm margin of surrounding visceral pleura. The implant was introduced through the surgical incision and sutured to the visceral pleura. A prescribed dose of 100-120 y was delivered to a volume within 0.5 cm rom the plane of the implant. Follow-up orthogonal films or CTs were obtained for dosimetric analysis. Kaplan-Meier analyses were used to estimate the local control, locoregional control, and overall survival rates. RESULTS: Of the 110 patients, 65 had stage IA and 45 had stage IB NSCLC. The mean preoperative FEV(1) was 47% of the predicted volume. With a median follow-up of 11 months (range 1-68 months), there were four recurrences within the radiation volume. The estimated 5-year local (in-field) control, locoregional control, and overall survival rates were 90%, 61%, and 18%, respectively. CONCLUSION: Vicryl mesh brachytherapy after sublobar resection for high-risk stage I NSCLC patients is a feasible procedure, which results in an excellent local (in-field) control rate.
