Correlation of computed tomography and serum tumor markers in metastatic retroperitoneal testicular tumor.

Preliminary findings of an apparently good correlation between computed tomography and serum tumor markers--human chorionic gonadotropin and alpha fetoprotein--are presented. These findings are from an ongoing prospective randomized study evaluating the efficacy of intensive chemotherapy and cytoreductive surgery in metastatic retroperitoneal testicular germ cell tumors.
