Perspectives on Quality of Life in Women with Breast Cancer.

Objectives: The objectives of the study are to assess changes in the quality of life amongst breast cancer patients undergoing treatment at a cancer institute in Colombia.

Materials and methods: Analytical observational prospective cohort study in patients over 18 years of age diagnosed with breast cancer. Health-related quality of life (HRQoL) was analysed using the EQ-5D-3L questionnaire and a Visual Analogue Scale measured at diagnosis and after a 6-month follow-up. Sociodemographic and clinical factors were analysed using a logistic regression model, with STATA 16 software.

Results: A total of 103 patients met the included criteria and were included in the study, with a median age of 56 years. According to the Tumour, Node, Metastasis classification of cancer stage, the majority of participants (35.92%) were in stage 2 of cancer. Multivariate analysis revealed that changes in HRQoL were significantly associated with age (odds ratio [OR] = 1.06, P = 0.001), radiotherapy (OR = 3.56, P = 0.038) and moderate anxiety and depression (OR = 5.54, P = 0.007).

Conclusion: While the overall quality of life in women with breast cancer showed a slight improvement over the 6 months, older patients and those receiving radiotherapy experienced a greater decline in health perception.
