Analysis of Factors Affecting the Quality of Life of Breast Cancer Patients Undergoing Chemotherapy at RSUD Gunung Jati Cirebon in 2024

Breast cancer was the leading cause of cancer-related deaths among women worldwide in 2020 and 2022, particularly in Indonesia. This disease is considered terrifying for many women because of its life-threatening nature, which can cause disruptions in various aspects of life. This means that breast cancer patients are vulnerable to a decreased quality of life. The importance of conducting routine assessments of quality of life lies in identifying and providing early interventions for patients at high risk of deterioration. This study aims to determine the factors that affect the quality of life of breast cancer patients. This research is a cross-sectional study involving breast cancer patients undergoing chemotherapy at RSUD Gunung Jati Cirebon during the period of June to July 2024. Data were collected through patient interviews and medical record reviews. Quality of life (QoL) was assessed using the Indonesian version of the EORTC QLQ-C30 questionnaire. Differences were found in the mean scores across various groups of variables. The results of statistical tests showed significant associations between age (p < 0.001), income (p < 0.001), cancer stage (p < 0.001), nutritional status (p = 0.045), and anxiety (p < 0.001) with the quality of life of breast cancer patients. Meanwhile, duration of illness (p = 0.073) and type of treatment (p = 0.359) had no significant effect on QoL. In summary, age, income, cancer stage, nutritional status, and anxiety were the factors that influenced the QoL of breast cancer patients undergoing chemotherapy.
