BACKGROUND: Extrapleural pneumonectomy is a treatment option for malignant pleural mesothelioma (MPM), but disease recurrence is common. Among different therapeutic options for recurrence, we have found no reports for second surgical procedures. METHODS: We retrospectively evaluated the types and outcomes of surgical management of solid recurrences of MPM, in a series of 74 patients treated with extrapleural pneumonectomy over a 20-year period. RESULTS: Of 57 patients for whom follow-up data were available, 11 patients experienced recurrent disease in the form of a solid mass, 1.5 to 12 years after the initial treatment; 8 of these patients had sufficiently good clinical conditions to undergo a second surgery with curative intent. Chest wall resection was performed in 4 cases of parietal recurrence, radical retroperitoneal resection was done in 3 cases of retroperitoneal relapse, and segmental resection of the remaining lung was done in one case of pulmonary metastasis. In this latter case, although computed tomographic images showed a solid mass, at surgery the disease was found to have a serosal nature, precluding the possibility of a curative surgery. Median survival after the second surgery was 14.5 months (range, 6 to 29); no association between survival and site of recurrence, age or disease-free interval was found. CONCLUSIONS: In this series, the second surgery did not offer the expected survival benefit of curative treatment strategies and should therefore be considered palliative. Second surgery may be a treatment option in a subset of patients who experience a solid recurrence of MPM that is symptomatic or near vital organs and who cannot undergo additional radiotherapy.

Abstract
BACKGROUND: Extrapleural pneumonectomy is a treatment option for malignant pleural mesothelioma (MPM), but disease recurrence is common. Among different therapeutic options for recurrence, we have found no reports for second surgical procedures. METHODS: We retrospectively evaluated the types and outcomes of surgical management of solid recurrences of MPM, in a series of 74 patients treated with extrapleural pneumonectomy over a 20-year period. RESULTS: Of 57 patients for whom follow-up data were available, 11 patients experienced recurrent disease in the form of a solid mass, 1.5 to 12 years after the initial treatment; 8 of these patients had sufficiently good clinical conditions to undergo a second surgery with curative intent. Chest wall resection was performed in 4 cases of parietal recurrence, radical retroperitoneal resection was done in 3 cases of retroperitoneal relapse, and segmental resection of the remaining lung was done in one case of pulmonary metastasis. In this latter case, although computed tomographic images showed a solid mass, at surgery the disease was found to have a serosal nature, precluding the possibility of a curative surgery. Median survival after the second surgery was 14.5 months (range, 6 to 29); no association between survival and site of recurrence, age or disease-free interval was found. CONCLUSIONS: In this series, the second surgery did not offer the expected survival benefit of curative treatment strategies and should therefore be considered palliative. Second surgery may be a treatment option in a subset of patients who experience a solid recurrence of MPM that is symptomatic or near vital organs and who cannot undergo additional radiotherapy.
