Background: Understanding the factors that contribute to variability in breast cancer-related lymphedema (BCRL) is an important first step in developing targeted interventions to improve quality of life in breast cancer patients. Although previous research studies have has identified many risk factors for BCRL, dietary habits and catheterization type have rarely been studied until the present.
Aim: This study aims to explore the effects of nursing factors such as dietary habits and catheterization type on breast cancer-related lymphedema (BCRL).
Methods: This retrospective cohort study included 1,476 breast cancer patients who underwent surgery between January 1, 2012, and September 1, 2020. Lymphedema was assessed with a validated self-report questionnaire. All research data were obtained from medical records and a follow-up database. Multivariate Cox regression was conducted to explore the effects of dietary habits and catheterization type on BCRL.
Results: The results showed an increased risk for BCRL among breast cancer patients who followed a high-fat diet prehospitalization (HR = 2.47; 95% CI = 1.55-3.94; P < 0.001), indwelling totally implantable venous access ports (TIVAPs) compared with indwelling needles (HR = 0.56; 95% CI = 0.35-0.90;P = 0.017) or indwelling peripherally inserted central catheters (PICCs) (HR = 0.69; 95% CI = 0.45-1.05; P = 0.086).
Conclusion: High-fat diet pre-hospitalization was an independent risk factor for lymphedema. The TIVAPs did not exert a protective effect on lymphedema compared with the PICC and indwelling needle. This study finding offers new insights to develop targeted interventions to decrease the incidence of lymphedema.
