Prognostic factors influencing survival in patients with advanced HER-2 positive breast cancer

A retrospective analysis was conducted using the medical records of 90 patients with advanced breast cancer admitted to our hospital from January 2018 to March 2023. Patients were divided into death group (n=66) and survival group (n=24). Logistic regression analysis was employed to examine the risk factors associated with survival in patients with advanced breast cancer. Cox regression analysis was utilized to identify independent prognostic factors affecting the 5-year survival of patients.
