LACOG0515 is a multicenter database of patients with germ cell tumors treated in Brazil, with 1,232 patients. The results showed a high rate of adjuvant chemotherapy in clinical stage I. For patients with advanced GCT, although our data demonstrate inferior PFS compared with the International Germ Cell Cancer Collaborative Group and other contemporary series, the survival rates were similar. Introduction: Germ-cell tumors (GCTs) are the most common malignancy in young men. There is a paucity of data on GCTs in developing countries. LACOG 0515 study aimed to evaluate clinical characteristics and treatment outcomes in patients with GCTs from Brazilian cancer centers. Materials and Methods: This is a retrospective cohort study evaluating male patients diagnosed with GCTs from 2000 to 2018 in 13 Brazilian hospitals. We described baseline characteristics, progression-free survival (PFS), and overall survival (OS). Results: A total of 1232 patients were included, with a median age of 30 years. Histology was seminoma in 47.1% and non-seminoma GCT (NSGCT) in 52.9%. The primary tumor site was testis in 96.5%. At diagnosis, clinical stage I was present in 68.1% and 34.7% and clinical stages IS/II/III in 31.9% and 65.2% of patients with seminoma and NSCGT, respectively. Following orchiectomy, 55.2% of patients with clinical stage I were managed with surveillance. The 5-year disease-free survival rates among patients with stage I were 98.0% in seminoma and 92.3% in NSGCT, with 5-year OS of 99.6% and 97.6%, respectively. Among patients with advanced disease (IS, II, and III), the 5-year PFS were 88.7% in seminoma and 68.7% in NSGCT, with 5y-OS of 97.6% and 82.8%, respectively. Conclusion: This is the largest Brazilian cohort of GCTs. Our results show a high rate of adjuvant chemotherapy in patients with clinical stage I. Although our data demonstrate slightly inferior PFS compared with the International Germ Cell Cancer Collaborative Group and other contemporary series, the OS rates were similar.
