Introduction: The incidence of lung adenocarcinomas has steadily increased over the last decades. The aim of this study was to assess the results of surgical treatment of multiple primary adenocarcinomas of the lung (MPAL) analyzing the radiological and histological features. Methods: From 1988 to 2005, 26 patients underwent surgical treatment for MPAL at our department, for a total of 52 tumors. Three patients had synchronous and 23 had metachronous tumors. Results: Thirty-seven tumors were classified as solid, two as ground-glass opacities (GGO) and 13 as mixed solid/GGO tumors on the basis of CT scan evaluation. Histology revealed 26 adenocarcinomas, five adenocarcinomas with a bronchioloalveolar (BAC) pattern and 21 BAC. There was no postoperative mortality. Five-year survival of patients with synchronous tumors was 66%. Survival of patients with metachronous tumors was 95% and 70% from the first and second operation. Patients with stage II and IIIa tumors had significantly reduced survival rates (p <0.05). Survival was 60% after lobectomy and 78% after wedge resection. Conclusions: Surgical treatment of MPAL is associated with favorable results. Sublobar resections, when technically feasible, provide adequate oncological management.
