Prevention of irreversible chemotherapy-induced ovarian damage in young women with lymphoma by a gonadotrophin-releasing hormone agonist in parallel to chemotherapy.

To examine whether the concomitant administration of a gonadotrophin-releasing hormone agonist (GnRHa) during combination chemotherapy to young women with lymphoma may facilitate preservation of gonadal function, a prospective clinical protocol was undertaken in 18 cycling women with lymphoma, aged 15-40 years. Thirteen patients suffered from Hodgkin disease (HD) and 5 from non-Hodgkin lymphoma. After informed consent a monthly injection of depot D-TRP6-GnRHa was administered for a maximum of 6 months starting prior to chemotherapy. Most of these patients (15/18) were treated with the MOPP/ABV(D) combination chemotherapy followed by mantle field irradiation in 10 patients. Hormonal profile [luteinizing hormone (LH), follicle stimulating hormone (FSH), oestradiol, testosterone, progesterone, insulin-like growth factor (IGF)-1, prolactin] was taken before the GnRHa/chemotherapy co-treatment, and monthly thereafter until resuming spontaneous ovulation and menses. This group of prospectively treated lymphoma patients was compared to a matched control group of 18 women (aged 17-40 years) who have been treated with chemotherapy, mostly MOPP/ABV (14/18), with (11) or without (7) mantle field radiotherapy. Fourteen had Hodgkin's and four non-Hodgkin's lymphoma. Gonadal function was determined clinically, hormonally (LH, FSH, oestradiol, progesterone), and sonographically. Two of the patients in each group died from refractory disease. Of the remaining 16 patients, 15 (93.7%) resumed spontaneous ovulation and menses within 3-8 months of termination of the combined chemotherapy/GnRHa co-treatment. In contrast, only seven (39%) of the 18 similarly treated patients in the control group (chemotherapy without GnRHa) resumed ovarian cyclic activity (regular menses). The other 11 experienced premature ovarian failure (POF) (61%). Out preliminary data suggest a possible significant protective effect of GnRHa co-treatment with chemotherapy from irreversible ovarian damage (POF).
