Aneuploidy in sperm of Hodgkin`s disease patients receiving NOVP chemotherapy
- Lawrence Livermore National Lab., CA (United States); and others
Induction of genetic damage in germ cells of young patients receiving chemo- or radiotherapy for cancers with probable cure, such as Hodgkin`s disease, is cause for concern. These young patients may someday desire children, and germ cell alterations presenting as numerical chromosomal abnormalities in sperm may place their future offspring at risk. To address this concern, we measured aneuploidy in sperm from eight young Hodgkin`s disease patients: four pre-treatment, four during treatment, and three over a 45 month period following treatment with NOVP (Novantrone, Oncovin, Vinblastine and Prednisone). Patients ranged in stage of disease from IA-IIEB and none had received prior radiation or chemotherapy. Using multi-chromosome sperm FISH with repetitive sequence probes specific for chromosomes X, Y and 8, we found a significant 2-4 fold increase in particular numerical chromosomal abnormalities during treatment which were limited in persistence post-treatment. Additionally, pre-treatment Hodgkin`s disease patients showed elevations in some numerical chromosomal abnormalities when compared to a healthy reference group. In several men, the fraction of aneuploid sperm did not return to healthy reference group levels even after completion of therapy. These results show that elevated sperm aneuploidy occurs in germ cells of young cancer patients during chemotherapy and suggest caution to prevent conceptions during this period. The elevated sperm aneuploidy appears transient, but in some cases never returns to healthy reference group levels.
