Abstract | OBJECTIVES: METHODS: The testicular cancer database was queried to identify patients with clinical Stage A nonseminomatous germ cell tumor with normalization of serum tumor markers after orchiectomy who had undergone retroperitoneal lymph node dissection. A total of 779 patients were identified. The preorchiectomy serum tumor marker level was recorded and categorized into the following subsets: AFP: less than 20 (normal), 20 to 100, 100 to 1000, and more than 1000 ng/dL; and beta-hCG: less than 5.0 (normal), 5 to 100, 100 to 1000, and more than 1000. The association between AFP, beta-hCG, and primary tumor size and retroperitoneal pathologic findings was determined. RESULTS: The retroperitoneal pathologic examination revealed metastatic disease in 207 patients (26.6%). The preorchiectomy serum beta-hCG level, as a categorical variable, was not predictive of positive retroperitoneal pathologic findings (P = 0.187). The preorchiectomy serum AFP did predict for positive retroperitoneal pathologic findings, with lower serum AFP levels associated with a greater incidence of retroperitoneal metastasis (P <0.001). The primary tumor size was not predictive of positive retroperitoneal pathologic findings (P = 0.113). CONCLUSIONS: Neither the primary tumor size nor the preorchiectomy beta-hCG level was predictive of retroperitoneal metastases. However, a normal preorchiectomy AFP level was associated with a greater incidence of retroperitoneal metastases.
