Theraputic Effect and Quality of Life Assessment in Patients with Neuropathic Pain Due to Bone Metastasis from Hepatocellular Carcinoma Treated with Radiotherapy and Pregabalin

Objective To evaluate the short-term efficacy and quality of life of primary hepatocellular carcinoma patients after radiotherapy and pregabalin treatment for neuropathic pain with bone metastasis. Methods 32 patients with primary hepatocellular carcinoma bone metastases were treated with radiotherapy combined with pregabalin treatment. Then, we prospectively studied the analgesic efficacy for neuropathic pain and quality of life, used the brief pain inventory and douleur neuropathique 4 questionnaire (DN4) to evaluate pain at baseline, one and two months after radiotherapy, assessed pain response using the international consensus endpoint definition of bone metastasis, and used European Organization for Research and Treatment of Cancer Research and Treatment Quality of Life Questionnaire (EORTC QLQ-C30) and bone metastasis module (QLQ-BM22) for quality of life assessment. Results One and two months after radiotherapy, the average DN4 score of neuropathic pain decreased, and the objective pain relief rates we
