[Administration of anti-HER2 and satisfaction of patients treated for breast cancer]. / Administration des anti-HER2 et satisfaction des patients avec un cancer du sein.

INTRODUCTION: Quality of life (QoL) and patient satisfaction are major concerns in oncology. METHODS: The aim of this prospective observational study was to evaluate these parameters according to the mode of administration of anti-HER2 (subcutaneous [SC] versus intravenous [IV]), the place of administration (Home Hospitalization or HOD versus hospital) for patients supervised by an advanced practice nurse (APN). RESULTS: Between January 2022 and June 2023, 32 patients were included. They were statistically more satisfied with subcutaneous management (P=0.0004), a result explained by the speed of administration (43.5%), comfort during administration (26%) even though some expressed pain on injection and felt less anxiety (26%). Management by the APN seems more appropriate when anti-HER2 drugs were administered in HOD. In HOD, patients perceived an overall improvement in their quality of life, appetite and cognitive abilities, with a reduction in fatigue, pain and depression (P<0.05). However, the rate of outsourcing to HOD remained too low (30.4%), as 56.3% of patients would have liked to be cared for in HOD if they had had the opportunity. CONCLUSION: SC administration of anti-HER2 under the supervision of an APN has advantages for the patient, resulting in greatest satisfaction and improved patient QOL, preferably in HOD.
