Background: Surgical resection is an important form of treatment for residual post-chemotherapy pulmonary masses in patients with non-seminomatous germ cell tumors. We analyzed the outcome and prognostic factors after surgery.
Methods: Between 1996 and 2001, 52 patients underwent pulmonary resection of thoracic masses following cisplatin-based chemotherapy. These patients' records were subsequently reviewed.
Results: The overall 5-year survival rate was 75.8 %. A significantly longer survival was observed using multivariate analysis in patients with normal serum AFP and/or hCG tumor marker levels and after complete surgical resection. In patients with viable malignant tumor cells in the resected specimen and in patients with only necrosis/fibrosis or teratoma, the 5-year survival rates were 49.6 % and 82.8 %, respectively. This difference was only statistically significant in univariate analysis.
Conclusions: We conclude that pulmonary resection in metastatic non-seminomatous germ cell tumors is a safe and effective treatment modality. Incomplete resection and elevated tumor marker levels, AFP and/or hCG, were identified as prognosis-related criteria for a poor outcome in multivariate analysis.
