Body Weight and Breast Cancer Treatment Response
Author Information
Author(s): G. Williams, A. Howell, M. Jones
Primary Institution: Christie Hospital and Holt Radium Institute
Hypothesis
Higher body weight may lead to a lower response rate and reduced survival in women undergoing endocrine therapy for breast cancer.
Conclusion
The study found no significant relationship between body weight and survival or response to endocrine therapy in women with advanced breast cancer.
Supporting Evidence
- High body weight was correlated with advanced tumor stage.
- There was no significant relationship between body weight and the presence of estrogen receptors.
- Patients above and below the median weight showed no significant differences in survival or response to therapy.
Takeaway
This study looked at how body weight affects breast cancer treatment. It found that being heavier doesn't change how well the treatment works or how long patients live.
Methodology
The study analyzed 227 women with advanced breast cancer, examining their body weight, treatment response, and survival rates.
Limitations
The study's sample size may limit the ability to detect small effects of body weight on treatment response.
Participant Demographics
The participants were 227 women with advanced breast cancer, with 59% presenting with operable disease and 41% with locally advanced tumors.
Statistical Information
P-Value
P=0.002 for tumor stage correlation, P=0.01 for PR positivity correlation, P=0.95 for survival comparison.
