Risk-Tailoring Radiotherapy for Endometrial Cancer: A Narrative Review

Simple Summary Endometrial cancer is the most common cancer of the female reproductive system in the United States and the second most common cancer of the female reproductive system worldwide. Treatment typically consists of upfront surgery. Postoperative therapy may include adjuvant radiation therapy and/or systemic therapy based on unique patient and pathologic characteristics. In this review, we explore the ways in which patient and tumor characteristics, current and emerging radiation technologies, and other cancer-directed treatments may be considered in developing personalized radiotherapy regimens for patients with endometrial cancer.Abstract Endometrial cancer is the most common gynecologic cancer in the United States and it contributes to the second most gynecologic cancer-related deaths. With upfront surgery, the specific characteristics of both the patient and tumor allow for risk-tailored treatment algorithms including adjuvant radiotherapy and systemic therapy. In this narrative review, we discuss the current radiation treatment paradigm for endometrial cancer with an emphasis on various radiotherapy modalities, techniques, and dosing regimens. We then elaborate on how to tailor radiotherapy treatment courses in combination with other cancer-directed treatments, including chemotherapy and immunotherapy. In conclusion, this review summarizes ongoing research that aims to further individualize radiotherapy regimens for individuals in an attempt to improve patient outcomes.
