Aim: About 90% of kidney cancers are renal cell carcinoma (RCC), and one-third of them are metastatic at the time of diagnosis. Most RCC metastases are to the lung. In this article, we present the results of a series of pulmonary metastasectomies for RCC in our institute. Materials and Methods: Twenty cases who underwent pulmonary metastasectomy for RCC between 2007 and 2017 were retrospectively reviewed. Patients were classified according to the age, sex, smoking history, duration of disease-free survival, number of metastatic lesions, median survival time, survival time after metastasectomy, type of surgery, and whether they received immunotherapy. Results: Fifteen of the patients were male and five were female. The mean age was 60-year-old (range: 28–86-year-old). Nineteen of the 20 patients had a history of nephrectomy. The median disease-free survival time was found to be 16.5 months while the median survival time after nephrectomy was 43.3 months. The number of detected metastatic lesions ranged from one to eight, and the location of the majority of them was intraparenchymal. Survival time after metastasectomy was found to be 20.6 months. Surgical approaches included bilateral metastasectomy through median sternotomy, unilateral wedge resection, and lobectomy through video-assisted thoracoscopic surgery or thoracotomy. Conclusion: The results of a combination of pulmonary metastasectomy and immunotherapy treatment were found to be better than immunotherapy or surgery alone. However, further study is needed with a larger series to support this argument.
