FRIDAY, May 27, 2016 (HealthDay News) — Triptorelin plus norethisterone (GnRHa) does not prevent chemotherapy-induced premature ovarian failure (POF) in young patients with lymphoma, according to a study published online May 23 in the Journal of Clinical Oncology.
Isabelle Demeestere, MD, PhD, from the Université Libre de Bruxelles in Belgium, and colleagues reported the final analysis of a cohort of 129 patients with lymphoma who were randomized to receive GnRHa or norethisterone alone (control) during chemotherapy. After two, three, four, and five to seven years of follow-up, ovarian function and fertility were reported. Overall, 67 patients (26.21 ± 0.64 years of age) had available data after a median follow-up of 5.33 and 5.58 years in the GnRHa and control groups, respectively.
The researchers found that the risk of POF was significantly increased according to age (P=0.047), the conditioning regimen for hematopoietic stem cell transplant (P=0.002), and the cumulative dose of cyclophosphamide >5 g/m² (P=0.019); the risk was not increased with co-administration of GnRHa during chemotherapy (odds ratio, 0.702; P = 0.651). Both groups had similar ovarian reserve, evaluated using anti-Müllerian hormone and follicle-stimulating hormone levels. In the GnRHa and control groups, 53 and 43 percent, respectively, achieved pregnancy (P=0.467).
“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,” the authors write.
