SOPPRESSIONE OVARICA CON LHRH ANALOGHI DURANTE CHEMIOTERAPIA PER LA PRESERVAZIONE DELLA FUNZIONE OVARICA E DELLA FERTILITÀ NELLE PAZIENTI CON CARCINOMA

Study Background
• Ovarian function loss and impaired fertility are possible
consequences of anticancer treatments and have a negative impact on global health of young breast cancer survivors1.
• Embryo and oocyte cryopreservation are the standard
procedure for fertility preservation2,3. No proven methods for preservation of ovarian function are yet available.
• According to the 2013 ASCO and ESMO guidelines, temporary ovarian suppression with LHRHa during
chemotherapy is still considered an experimental strategy to preserve ovarian function and fertility2,3.

Study Design
• Quantitative synthesis of randomized trials aiming to evaluate the efficacy and safety of temporary ovarian suppression with LHRHa during chemotherapy as a
strategy to preserve ovarian function and fertility in young breast cancer patients.
• The work was done and reported according to the PRISMA guidelines for reporting of systematic reviews.
• A literature search using PubMed, Embase and the
Cochrane Library was performed with no date restriction up to April 30th, 2015; abstracts presented at ASCO, ASCO breast, SABCS and ESMO meetings were also searched.
Eligibility Criteria
• Inclusion criteria:
a) randomized trials designed to evaluate the efficacy of the addition of LHRHa to chemotherapy in terms of POF and/or fertility after chemotherapy;
b) studies conducted in early-stage premenopausal breast cancer patients who were candidates for neo-adjuvant and/or adjuvant chemotherapy;
c) the odds ratio (OR) for POF and/or pregnancies had to be reported or could be computed from the data presented in the selected studies.
• Exclusion criteria:
a) randomized trials designed to evaluate the efficacy of the addition of LHRHa to chemotherapy in terms of POF and/or fertility after chemotherapy in patients with autoimmune disease or tumors other than breast cancer;
b) non-randomized studies conducted to evaluate the role of LHRHa during chemotherapy as a strategy to preserve ovarian function and/or fertility;
c) ongoing studies which had not yet been presented or published at the time of the literature search.
Study Objectives and Endpoints
• Primary objective: to compare the incidence of treatment- related POF between patients treated with concurrent
temporary ovarian suppression with LHRHa during
chemotherapy and those who received chemotherapy alone.
• Secondary objectives:
a) to compare the incidence of treatment-related amenorrhea 1 year after the end of chemotherapy;
b) to compare pregnancy rates;
c) to evaluate the impact of concurrent administration of LHRHa and chemotherapy on disease-free survival (DFS).
Statistical Considerations
• Fixed effect model was estimated with the Mantel-Haenszel method for OR and the inverse variance method for HR.
• To estimate the random effect model, the method of DerSimonian and Laird was used.
• The Higgins’ I2 index was computed to obtain a quantitative measure of the degree of inconsistency in the results of the studies included.
• A visual inspection of the funnel plot and the Harbord’s asymmetry test were used to assess the likelihood of publication bias.

Chemotherapy + LHRHa
Sverrisdottir et al.:
1) “Sverrisdottir 1”: chemotherapy + LHRHa vs chemotherapy alone
2) “Sverrisdottir 2”: chemotherapy + LHRHa + tamoxifen vs chemotherapy + tamoxifen
Elgindy et al.:
1) “Elgindy 1”: early chemotherapy alone vs early chemotherapy + LHRHa + LHRH antagonist 2) “Elgindy 2”: delayed chemotherapy vs delayed
chemotherapy + LHRHa

• Temporary ovarian suppression with LHRHa in young breast cancer patients is associated with a reduced risk of
chemotherapy-induced POF and seems to increase the
pregnancy rate, without apparent negative consequence on prognosis.
• The use of LHRHa during chemotherapy might be considered a valid option for women interested in
preserving their ovarian function, and might also play a role in increasing the likelihood of becoming pregnant after
cessation of chemotherapy
