Advanced Triple-Negative Breast Cancer

Our focus within this review is to summarize key advances and new therapeutic approaches within advanced triple-negative breast cancer. In addition, we highlight the importance of multidisciplinary management, discussing key issues for patients and importance of the supportive role that specialist nurses provide.

Peer-reviewed literature, clinical practice guidelines, clinical trial, and government websites.

Triple-negative breast cancer is a highly heterogeneous subtype of breast cancer, often associated with a less favorable prognosis compared to other types. Significant advances in our understanding of specific mutations and signaling pathways within this subtype, coupled with expanding therapeutic options, has broadened the treatment landscape considerably. While chemotherapy traditionally formed the mainstay of treatment, new therapeutics such as immunotherapy, targeted agents, and antibody-drug conjugates in first-line and subsequent-line settings are now available. It is essential for all those who care for this patient group to be up-to-date on current practice and emerging treatments, so patients receive the support they need and deserve.

Nurses need to become familiar with new systemic anticancer therapies within advanced triple-negative breast cancer to provide patients with adequate information about new treatment options and support with potential treatment-associated toxicities. It is important for nurses to be able to recognise key issues facing patients with a diagnosis of advanced triple-negative breast cancer, to gain a deeper understanding of both the physical and psychosocial support required, signposting or referring patients to additional support services if needed.
