Multicenter Study Observational StudyPredictors of Pain Palliation After Radiation Therapy for Painful Tumors: A Prospective Observational Study.
Although radiation therapy (RT) is an important part of treatment for cancer pain, prediction of the patient's pain response remains difficult. We evaluated the characteristics of patients, their tumors, and their pain to identify the predictors of pain palliation after RT for painful tumors. ⋯ Patients with hematologic tumors, a neuropathic component of the index pain, and no treatment with opioid analgesics before RT were more likely to experience pain palliation after RT.
