The use of intensity modulated radiation therapy (IMRT) for postoperative management of uterine cancer has increased significantly between 2004 and 2012, although not resulting in significantly improved survival, a recent study found. The National Cancer Database was queried and identified 7,839 women with endometrial adenocarcinoma who underwent hysterectomy followed by external beam radiation during the study period. Researchers found:
- IMRT utilization increased from 1.9% in 2004 to 32.4% in 2012 (aOR, 24.90).
- Black race was associated with lower IMRT usage compared to whites (OR, 0.60).
- IMRT was not associated with significantly increased survival (HR, 0.86).
- Black race and positive nodes were associated with decreased survival; whereas private insurance and higher income were associated with improved survival.
