ABSTRACT
Loss of heterozygosity in the SMARCA4 gene is a hallmark feature of small cell carcinoma of the ovary, hypercalcemic type (SCCOHT), an aggressive ovarian cancer occurring in young adults and adolescents with an average age of 23 years and a median survival of less than fifteen months following diagnosis. Patients with germline pathogenic variants of SMARCA4 have a genetic predisposition to developing this aggressive ovarian cancer, a condition called rhabdoid tumor predisposition syndrome type 2 (RTPS2). Given the limited efficacy of surveillance imaging for ovarian neoplasm and the absence of an identified biomarker for the progression of this disease, asymptomatic patients who are found to possess pathogenic variants of the SMARCA4 gene following genetic testing are advised to consider risk-reducing bilateral salpingo-oophorectomy to eliminate the risk of SCCOHT. Given the reproductive impacts of this procedure, bioethical consultation must be considered when counseling patients with RTPS2, particularly for those who have not completed their desired course of family planning. In this report, we describe the bioethical considerations and outcomes for the case of a 6-year-old female with a pathogenic variant of SMARCA4 who underwent risk-reducing bilateral salpingo-oophorectomy (RRBSO). To our knowledge, this is the first time that this procedure has been reported in a prepubertal individual for cancer prevention in a patient with RTPS2.
