Abstract
Aim Breast cancer is the most prevalent cancer in South African females, making up 27.1% of all histologically diagnosed cancers in 2020. Although genetic technology and awareness of genetic counselling have improved, genetic counselling services in South Africa remain largely inaccessible. Clinical genetic services are only formally available in four South African provinces and few outreach programmes exist for small towns and cities. Until 2019, genetic counselling services were unavailable in the North West province; however, since then, genetic counsellors from the National Health Laboratory Service and the University of the Witwatersrand have provided genetic counselling services to patients at the Breast Clinic at Potchefstroom Hospital regularly each year. Method The aim of this pilot study was to perform a retrospective file review and report on the implementation and outcomes of the genetic counselling service at the Breast Clinic at Potchefstroom Hospital, from its inception in 2019, until November 2022. Fifty-two patients attended a genetic counselling consultation during that period. Results The majority of patients (83.7%) were diagnosed with an invasive ductal carcinoma, and 57.7% of the patients had a family history of cancer. A total of 62.8% of patients had a histologic grade 3 tumour. A total of 25.5% (12/47) of patients tested positive for a pathogenic variant in BRCA1 or BRCA2. A total of 45 at-risk first-degree relatives were identified who could benefit from predictive testing. Conclusions This study highlights the benefit of offering clinical genetics services through outreach clinics. Being able to offer this service is not only beneficial for the management of the affected individuals, but also for their at-risk relatives. The initiative serves as a positive example of how limited resources can be extended to benefit patients.
