Introduction: Triptorelin is a luteinizing hormone-releasing hormone analog (LH-RHa) inducing ovarian function suppression (OFS). It is approved by FDA and EMA in association with tamoxifen or aromatase inhibitor (AI) and with fulvestrant and palbociclib in premenopausal women with hormone receptor (HR)-positive breast cancer. Its potential role to preserve ovarian function during chemotherapy has also been recently clarified. Areas covered: Several studies have investigated the role of adding OFS to tamoxifen and aromatase inhibitors as adjuvant treatment in early breast cancer. The addition of triptorelin is not free from adverse events as the combination with tamoxifen and exemestane resulted in an increase of endocrine-deprivation symptoms. Clinical trials have explored the combination of LH-RHa with chemotherapy in fertility preservation, demonstrating no detrimental effect on patients’ oncological outcome. This is all discussed in this evaluation. Expert opinion: Triptorelin represents a standard-of-care in premenopausal women with HR-positive breast cancer and in some cases of male breast cancer. In the adjuvant setting, a personalized approach is required to combine LH-RHa with the right partner considering the risk of recurrence and the toxicity profile. LH-RHa may be offered to breast cancer patients in the hope of reducing the likelihood of chemotherapy-induced ovarian insufficiency.
