IntroductionRenal cell carcinoma (RCC) represents approximately 2% of all tumors, and about 30% of patients are affected by metastatic lesions at diagnosis (1,2). About 20% to 40% of patients develops a metastatic disease after nephrectomy (3) and lung is one of the sites most frequently affected by RCC metastases (second after liver) (4). Patients that receive no treatment for metastatic RCC (mRCC) have a 0-18% 5-year survival (5). Nonsurgical therapy for mRCC has limited efficacy, with a median overall survival (OS) reported between 26.4 and 32.0 months (6,7) for mRCC patients receiving several agents targeting angiogenesis or the mTOR pathway, in addition to traditional chemotherapeutic regimens and immunotherapy (8). On the contrary, the 5-year survival rates data published in literature after pulmonary surgery for metastasectomy from 36-54% (9,10), emphasizing the role of surgery as the Background: The lung is one of the sites most frequently affected by metastatic renal cell carcinoma
