Abstract

Background: We investigate the effects of chemotherapy and surgical treatment on the extragonadal germ cell tumor of which poor prognosis has been reported. Methods: We analyzed the prognosis of 31 patients with extragonadal germ cell tumor treated at Kanagawa Cancer Center by factors including patient background, the condition of disease, and treatments. Result: As the prognostic factors for the overall survival, pulmonary metastasis at the first visit (p=0.011), no normalization of tumor markers after induction chemotherapy (p=0.014) and no residual tumor resection irrespective with (p=0.03) or without (p=0.001) normalized tumor makers were significantly poor prognosis in the univariate analysis. On the other hand, patients who underwent residual tumor resection with un-normalized tumor markers (desperation surgery) tended to show a better prognosis compared to previous reports. Conclusion: Although this was an investigation in a rather small group, regardless of the tumor markers normalization, resection of a residual tumor showed the tendency of improving the prognosis of extragonadal germ cell tumor. It was considered that resection of a residual tumor with a high degree of expertise could lead to better treatment outcomes.
