Obesity Does Not Influence Management of Advanced Breast Cancer in the Elderly.

BACKGROUND

Obesity is becoming increasingly common in the elderly population, and it adds to the complexity of treatment decisions in this population. We aimed to investigate whether body mass index (BMI) affects care in this subset of patients.

PATIENTS AND

METHODS

We performed a retrospective chart review on 118 patients over the age of 70 years diagnosed with breast cancer and pathologically proven axillary disease over an 8-year period at an urban academic hospital and compared BMI to treatment received, clinical stage, and hormone receptor status.

RESULTS

Performance of radiation therapy, axillary surgery, and chemotherapy was compared in the elderly population over lower and higher BMI, and no significant difference was detected. Although there was a trend for increasing clinical stage to be associated with a lower BMI, this was not statistically significant (P = .06).

CONCLUSION

Obesity does not appear to influence treatment decisions in patients over the age of 70 years. Breast cancer providers should turn to other patient and clinical factors when deciding treatment plans in this patient population. Further investigation is needed to examine how obesity influences tumor biology, diagnosis, and treatment decisions.
