Background: This is an institutional review of surgical management of second pulmonary tumours in patients with history of Non-small Cell Lung Cancer (NSCLC) resection according to The American College of Chest Physicians' (ACCP) revision to the Martini and Melamed's criteria for the classification of multiple primary lung cancers (MPLC). Methods: All patients who underwent iterative pulmonary resections for pulmonary metastasis (Group A) or MPLC (Group B) between 2006 and 2012 were reviewed and their survivals compared accordingly. The main criteria of insertion in Group B were different histology and the same histology with disease-free interval ≤ 4 years; we excluded loco-regional recurrence in nodes and/or on bronchial stump. Results: Group A: Twenty patients; Disease free time (DFT) after first operation was 15.2 months (range 2-44). One, two and three years overall survival after second resection was 74%, 29%, 14% respectively. Group B: Thirty-six patients. One, two and three years overall survival was 94%, 81%, and 69% respectively. No statistical differences on outcome were found between the two groups in spite of the apparent worse survival rate for Group A (p. = .197). Conclusions: A further resection for additional nodules, whether designated as intrapulmonary metastases or second primary NSCLC, can be an appropriate curative strategy in selected patients with unimpaired respiratory function and no evidence of distant metastatic disease. The site, the extent of the second resection, the histology and even the stage are unlikely to be related to survival.

Abstract

Background: This is an institutional review of surgical management of second pulmonary tumours in patients with history of Non-small Cell Lung Cancer (NSCLC) resection according to The American College of Chest Physicians' (ACCP) revision to the Martini and Melamed's criteria for the classification of multiple primary lung cancers (MPLC). Methods: All patients who underwent iterative pulmonary resections for pulmonary metastasis (Group A) or MPLC (Group B) between 2006 and 2012 were reviewed and their survivals compared accordingly. The main criteria of insertion in Group B were different histology and the same histology with disease-free interval ≤ 4 years; we excluded loco-regional recurrence in nodes and/or on bronchial stump. Results: Group A: Twenty patients; Disease free time (DFT) after first operation was 15.2 months (range 2-44). One, two and three years overall survival after second resection was 74%, 29%, 14% respectively. Group B: Thirty-six patients. One, two and three years overall survival was 94%, 81%, and 69% respectively. No statistical differences on outcome were found between the two groups in spite of the apparent worse survival rate for Group A (p. = .197). Conclusions: A further resection for additional nodules, whether designated as intrapulmonary metastases or second primary NSCLC, can be an appropriate curative strategy in selected patients with unimpaired respiratory function and no evidence of distant metastatic disease. The site, the extent of the second resection, the histology and even the stage are unlikely to be related to survival.
