THE ROLE OF RADIATION THERAPY IN LOCALLY ADVANCED BREAST CANCER IN A PATIENT WITH LI-FRAUMENI SYNDROME

Objectives: Li-Fraumeni syndrome (LFS) is associated with many different cancers, including early onset breast cancer. Due to an increased risk of radiation-induced malignancy, radiation therapy is often avoided in this patient population. This case study evaluates a 38-year-old female with a history of juvenile granulosa cell tumor of the ovary and malignant phyllodes tumor of right breast, who subsequently developed bilateral invasive ductal carcinoma and was treated with bilateral mastectomies. Studies show that in a high-risk patient, post-mastectomy radiation therapy (PMRT) should not be ruled out due to a history of LFS, as the benefit of PMRT may outweigh the risk of a radiation-induced malignancy.
