Reduced Risk of Lymphedema With Intensity-modulated Radiation Therapy Compared With 3-dimensional Conformal Radiation Therapy in Patients With Cervical Cancer Who Received Postoperative Pelvic Radiation Therapy.

Objectives: To compare the long-term adverse events of intensity-modulated radiation therapy (IMRT) with those of 3-dimensional conformal radiation therapy (3D-CRT) in patients with intermediate-risk and high-risk uterine cervical cancer who underwent postoperative pelvic radiation therapy (PORT).

Methods: We reviewed the medical records of 177 patients with cervical cancer who underwent radical surgery and PORT. IMRT and 3D-CRT were administered to 93 and 84 patients, respectively.
