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.

(8)

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.

(9)

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).

(10)

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.

• 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
