    Background:
    Testicular Germ-cell tumors are a common cancer in adults younger than 30 years-old. Extensive dissemination and high senitivity to chemotherapy are their principal characteristics. Chemotherapy is the standard of care, with an 80% probability of complete biochemical response with first line chemotherapy. Surgical resection of residual lesions after chemotherapy is indicated in some cases to rule out the presence of mature teratoma or viable tumor.
    
    Method:
    Retrospective chart review of patients with metastastic testicular Germ-cell tumors treated with chemotherapy and pulmonary metastasectomy from January 2006 to December 2014.
    
    Result:
    We found 56 cases with complete data for revision. Mean age was 25 years (16-48) Patients with lung metastases at diagnosis were 83.9%. All patients were treated with chemotherapy after initial orchiectomy. Preoperative serum tumor markers were negative in 44 patients (78%) Thoracotomy was performed in 48 cases (85.7%) and minimally invasive surgery in 8 cases (14.3%) Pulmonary wedge resection was performed in 52 patients (92.8%) and a lobectomy was required in 4 patients (7.2%) A R0 resection was achieved in 98.3%. Necrosis was reported in 25 cases (44.6%), mature teratoma in 17 (30.4%), viable germ-cell tumor in 13 patients (23.2%) and 1 case with seminoma (1.8%) All patients with viable tumor were offered postoperative chemotherapy. Median follow-up was 53.2 months (6-110). Median Overall Survival has not reached. Factors associated with improved survival were negative preoperative serum tumor markers and abscense of viable germ-cell tumor on resected specimens. Figure 1
    
    
    
    Conclusion:
    Removal of residual lesions after chemotherapy serves a double purpose, as an adjuvant treatment to chemotherapy allowing for “local” control of metastases and it also provides information about response to chemotherapy, with implications on prognosis and guiding postoperative treatment. In our cohort we demonstrate that despite a high proportion of viable tumors on surgical specimen, multi-modality treatment including lung metastasectomy is associated with prolonged survival
