BACKGROUND: The aim of this study was to evaluate the long-term gonadal sequelae after treatment for childhood Hodgkins lymphoma with combination chemotherapy, using up to date fertility parameters and andrological evaluation, including for the first time inhibin B.
METHODS: There were 56 male patients treated from 1974–1998 for childhood Hodgkins lymphoma with combination chemotherapy ABVD or EBVD (adriamycin/epirubicin, bleomycin, vinblastine, dacarbazine) with or without MOPP (mechlorethamine, vincristin, prednisone, procarbazine) with the intention to avoid radiotherapy. These men were studied 15.5 years (range 5.6–30.2 years) after cessation of therapy. Serum follicle stimulating hormone (FSH), luteinizing hormone (LH), inhibin B, testosterone, sex hormone-binding globulin (SHBG), sperm concentration and sperm DNA integrity were determined.
RESULTS: In men treated with MOPP, median FSH and LH were significantly increased (P < 0.001) and inhibin B (17.5 versus 143 ng/l; P < 0.001) and sperm concentration (1.05 versus 49.5 x 106/ml; P < 0.05) were significantly decreased compared with patients treated without MOPP. The number of MOPP courses was significantly correlated with FSH and inhibin B levels. Only inhibin B showed an independent correlation with sperm concentration (r = 0.86; P < 0.001).
CONCLUSIONS: The use of MOPP chemotherapy causes permanent gonadal damage in the far majority of male survivors of childhood Hodgkins lymphoma and inhibin B is the most valuable serum marker for gonadal function.
