BACKGROUND: Treatment-related premature ovarian insufficiency (POI) can result in early-onset menopause and infertility. AIMS: To assess the prevalence of goserelin use for POI prevention in women with cancer since it was listed by the Australian Pharmaceutical Benefits Scheme in 2018 for this indication. METHODS: This retrospective study included women aged 18-45 years who received curative-intent alkylating chemotherapy for a malignancy between August 2020 and December 2022 at the Peter MacCallum Cancer Centre. The co-primary end-points were (i) documentation of a discussion with the patient regarding goserelin for POI prevention and (ii) prescription of goserelin for POI prevention prior to chemotherapy commencement. RESULTS: Sixty-six patients were eligible. Fifty patients (76%) had a documented discussion regarding goserelin for POI prevention and 53 patients (80%) were prescribed goserelin for POI prevention. Nulliparous women were more likely to have a discussion regarding goserelin (P = 0.004). Younger women, nulliparous women and those referred to a fertility service were more likely to have been prescribed goserelin for POI prevention (P = 0.003, P = 0.001 and P = 0.002 respectively). Twenty-one of 53 patients (40%) who received goserelin had the first dose administered ≥7 days before chemotherapy commencement. CONCLUSION: One-quarter of eligible patients did not have a documented discussion regarding goserelin, despite the negative consequences of POI. Efforts are needed to increase the discussion and use of goserelin in all premenopausal women regardless of their fertility interests and to ensure timely administration in those who choose to receive it.
