Alpha-fetoprotein and human chorionic gonadotropin in the management of testicular tumors.
Alpha-fetoprotein and human chorionic gonadotropin levels were measured by radioimmunoassays in 260 patients with genitourinary diseases, including 93 patients with testicular tumors. Elevations of alpha-fetoprotein and human chorionic gonadotropin were associated only with non-seminomatous germ cell testicular tumors. Our 32-month experience with serial measurements of the 2 markers in patients with these tumors shows that alpha-fetoprotein and human chorionic gonadotropin must be determined and that together they serve as accurate and sensitive indicators of metastases and are helpful in determining the effectiveness of therapy. However, they have limited value in the differential diagnosis of scrotal masses.
