    Abstract:
    OBJECTIVE: Because pleuropneumonectomy is associated with a high mortality rate, its indication for the treatment of Masaoka stage IVa thymoma is debated. We reviewed retrospectively our single-center experience in order to determine if the benefits warrant the risk of such procedure. METHODS: Between 1970 and 2009, 17 patients (12 men and 5 women) with a mean age of 44 years (range, 25-62 years) underwent a pleuropneumonectomy for a Masaoka stage IVa thymoma in our institution. Eight patients had recurrent thymoma after a mean postoperative period of 47 ± 28 months, and nine patients presented de novo with stage IVa disease. A multimodality treatment including chemotherapy, radiotherapy, or both was performed in 14 (82%) patients. RESULTS: Eight patients (47%) experienced a major postoperative complication, including four broncho-pleural fistulae (23%). There were no operative deaths and the 30-day mortality was 17.6% (3/17). But two patients died at 2 and 3 months, increasing the postoperative mortality to 29.4% (5/17). Complete resection was achieved in 11 (65%) patients. By univariate analysis, myasthenia gravis was the only risk factor for broncho-pleural fistulae. With a median survival of 76 months and median follow-up of 59 months (range, 1-262 months), 5-year and 10-year survivals were 60% and 30%, respectively. During follow-up, a recurrence occurred in two patients at 26 and 87 months, respectively, which was treated medically without success. CONCLUSIONS: Pleuropneumonectomy for Masaoka stage IVa thymoma is associated with a high morbid-mortality rate. However, included in a multimodality strategy and in highly selected patients this procedure may provide good long-term survival.
