Long-term follow up of ovarian function in women treated with MOPP chemotherapy for Hodgkin's disease.

Twenty-seven women previously treated with MOPP (mechlorethamine, vincristine, procarbazine, prednisone) chemotherapy were evaluated to determine the status of ovarian function. All patients had completed therapy a median of nine years earlier and had a median age of 30 years at the time of evaluation. Persistent amenorrhea has occurred in 11 of 24 patients (46 percent) treated with MOPP alone or MOPP plus radiation excluding the pelvis. Of patients with amenorrhea, 89 percent were older than age 25 at the time of treatment. In contrast, 80 percent of patients younger than age 25 at treatment continue to menstruate regularly. The time from diagnosis to amenorrhea was significantly shorter in the older patients (p = 0.001). Evaluation of serum gonadotropin and estradiol levels confirms ovarian failure as the cause of amenorrhea in all patients. Overall, these 27 patients have borne 13 normal children subsequent to chemotherapy. This long-term follow-up study demonstrates that chemotherapy-induced ovarian failure is age-related, that ovarian failure is often gradual in onset following the completion of chemotherapy and that, to date, the children born of women treated with this chemotherapy regimen appear to be entirely normal.
