Profile of Breast Cancer Patients Experiencing Recurrence Post-MRM

Abstract

Breast cancer is the most common type of cancer in women worldwide and a leading cause of cancer-related deaths in women. The incidence of cancer in Indonesia ranks 8th in Southeast Asia and 23rd in Asia. This research is a descriptive study aiming to provide an overview of breast cancer patients experiencing recurrence post-MRM at Dr. Soetomo Hospital from 2021 to 2025. This research employs a descriptive observational study design. Data collection will be conducted using a cross-sectional approach, drawing information from the medical records of breast cancer patients who experienced recurrence post-MRM at RSUD Dr. Soetomo Surabaya. The majority of patients are in the ≥55 years age group, which reflects a higher tendency for recurrence in older age. The distribution of anatomical pathology (AP) types shows a dominance of Ductal and Lobular types, consistent with the most commonly found histological types of breast cancer. The majority of patients in this study were in an advanced stage (metastatic breast cancer), indicating that the recurrent cases examined were systemic. The majority of patients experiencing recurrence were in the age group of ≥55 years, all patients were in an advanced stage (metastatic breast cancer) at the last evaluation, and the dominant histopathological subtype was luminal B Her2 negative.
