Inflammation of breast fat during radiotherapy could decrease its effectiveness for breast cancer
What is it about?
Twenty five doses of radiotherapy are often given to the whole breast after surgical removal of the tumor to eliminate remaining cancer cells. We showed that exposure of human breast fat to therapeutic doses of radiation caused inflammation and the production of an enzyme called autotaxin. Autotaxin produces a compound called LPA, which protect cancer cells against radiation-induced damage. LPA also promotes the production of scar tissue, a serious side effect of radiotherapy. Therefore, blocking this inflammation and the production of LPA during radiotherapy could improve the efficiency of the radiation therapy and decrease the formation of scar tissue.
Why is it important?
Our work provides information that blocking the effects of radiation in increasing the effects of autotaxin and thereby the production of LPA could provide a novel strategy for improving the effectiveness of radiotherapy for breast cancer. This strategy could also decrease the side effects of radiation in stimulating scar tissue formation.
