  • Title: Spermatic cord beta-human chorionic gonadotropin levels in seminoma and their clinical implications.
    Author: Mumperow E, Hartmann M.
    Journal: J Urol; 1992 Apr; 147(4):1041-3. PubMed ID: 1372658.
    Abstract:
    Current opinions differ as to the biological significance and treatment of pure seminoma associated with the serological establishment of beta-human chorionic gonadotropin. Between December 1987 and April 1990, 147 patients with malignant testicular tumors were treated. Of these patients 47 (32%) had a pure seminoma. In 35 of the 47 patients we measured the tumor markers beta-human chorionic gonadotropins and alpha-fetoprotein in the cubital vein blood and testicular vein blood. There were elevated beta-human chorionic gonadotropin levels in the cubital veins of 26% of the patients, in agreement with the literature. However, elevated levels were found in the testicular veins of 80% of the patients, which reflects the high sensitivity of marker identification in testicular vein blood. Apparently, most seminomas produce beta-human chorionic gonadotropin even if it is not detectable in the cubital vein. We believe that the presence of this marker in patients with pure seminoma is not an indication of greater tumor aggressiveness but of tumor mass.
