The Addition Of Radiation Therapy Found To Improve Survival In Breast Cancer Patients
Researchers say adding radiation therapy to a treatment regimen already consisting of chemotherapy and radical mastectomy leads to better survival outcomes among women with high-risk breast cancer with few long term side effects.

Ina study done between 1979 and 1986, 318 patients were randomly assigned to receive radiation therapy or no radiation at all. In a 20-year follow-up, researchers found the chemotherapy/radiation combination, compared with chemotherapy alone, was associated with vast improvements for the patients. These included a 32-percent reduction in breast cancer mortality and a 27-percent reduction in overall mortality. Additionally, long-term toxic effects, including cardiac deaths, were acceptable for both groups of patients.

Thus researchers say, their results, and those from other studies, confirm that in situations where residual disease remains, adjuvant chemotherapy alone in high-risk breast cancer patients is suboptimal and that the addition of locoregional radiation therapy is important to achieve the highest cure rate.

In conclusion researchers urge that more randomized controlled trials be done to resolve uncertainties regarding the same .
