Before And After

This study aimed to investigate the effect of gonadotropin-releasing hormone agonist (GnRHa) treatment on the expression of neuritin 1 (NRN1) in women with ovarian endometriosis. We collected tissues and serum from women with endometriosis treated with (n = 45) or without (n = 37) GnRHa. NRN1 mRNA and protein levels were measured using qPCR and Western blot. Immunolocalization of NRN1 in endometriotic tissues was examined using immunohistochemistry. In addition, a follow-up study was carried out to monitor the serum level of NRN1 in patients before and after GnRHa treatment. Both mRNA (p = 0.046) and protein (p = 0.0155) levels of NRN1 were significantly lower in endometriotic tissues from patients receiving GnRHa treatment compared to the untreated group. Both epithelial and stromal cells of endometriotic tissues from untreated women with endometriosis exhibited stronger staining of NRN1 but not in those who were treated with GnRHa. The follow-up study showed that the serum level of the NRN1 concentration decreased significantly from 1149 ± 192.3 to 379.2 ± 80.16 pg/mL after GnRHa treatment (p = 0.0098). The expression of NRN1 was significantly lower in women with ovarian endometriosis treated with GnRHa. These results suggest that NRN1 may be a biomarker response to the effect of GnRHa treatment for patients with ovarian endometriosis.

Purpose To assess the efficacy of gonadotropin-releasing hormone agonist (GnRHa) in preventing chemotherapy-induced ovarian failure in patients treated for Hodgkin or non-Hodgkin lymphoma within the setting of a multicenter, randomized, prospective trial. Patients and Methods Patients age 18 to 45 years were randomly assigned to receive either the GnRHa triptorelin plus norethisterone (GnRHa group) or norethisterone alone (control group) concomitantly with alkylating agents containing chemotherapy. The primary end point was the premature ovarian failure (POF) rate (follicle-stimulating hormone [FSH] ≥ 40 IU/L) after 1 year of follow-up. Results Eighty-four of 129 randomly assigned patients completed the 1-year follow-up. The mean FSH values were higher in the control group than in the GnRHa group during chemotherapy; however, this difference was no longer observed after 6 months of follow-up. After 1 year, 20% and 19% of patients in the GnRHa and control groups, respectively, exhibited POF (P = 1.00). More than half of patients in each group completely restored their ovarian function (FSH < 10 IU/L), but the anti–Müllerian hormone values were higher in the GnRHa group than in the control group (1.4 ± 0.35 v 0.5 ± 0.15 ng/mL, respectively; P = .040). The occurrence of adverse events was similar in both groups with the exception of metrorrhagia, which was more frequently observed in the control group than the GnRHa group (38.4% v 15.6%, respectively; P = .024). Conclusion Approximately 20% of patients in both groups exhibited POF after 1 year of follow-up. Triptorelin was not associated with a significant decreased risk of POF in young patients treated for lymphoma but may provide protection of the ovarian reserve.

Purpose We have reported previously that after 1-year follow up, gonadotropin-releasing hormone agonist (GnRHa) did not prevent chemotherapy-induced premature ovarian failure (POF) in patients with lymphoma, but may provide protection of the ovarian reserve. Here, we report the final analysis of the cohort after 5 years of follow up. Patients and Methods A total of 129 patients with lymphoma were randomly assigned to receive either triptorelin plus norethisterone (GnRHa group) or norethisterone alone (control group) during chemotherapy. Ovarian function and fertility were reported after 2, 3, 4, and 5 to 7 years of follow up. The primary end point was POF, defined as at least one follicle-stimulating hormone value of > 40 IU/L after 2 years of follow up. Results Sixty-seven patients 26.21 ± 0.64 years of age had available data after a median follow-up time of 5.33 years in the GnRHa group and 5.58 years in the control group (P = .452). Multivariate logistic regression analysis showed a significantly increased risk of POF in patients according to age (P = .047), the conditioning regimen for hematopoietic stem cell transplant (P = .002), and the cumulative dose of cyclophosphamide > 5 g/m2 (P = .019), but not to the coadministration of GnRHa during chemotherapy (odds ratio, 0.702; P = .651). The ovarian reserve, evaluated using anti-Müllerian hormone and follicle-stimulating hormone levels, was similar in both groups. Fifty-three percent and 43% achieved pregnancy in the GnRHa and control groups, respectively (P = .467). Conclusion To the best of our knowledge, this is the first long-term analysis confirming that GnRHa is not efficient in preventing chemotherapy-induced POF in young patients with lymphoma and did not influence future pregnancy rate. These results reopen the debate about the drug’s benefit in that it should not be recommended as standard for fertility preservation in patients with lymphoma.
