Iodine-125 seed implantation combined with arterial chemoembolization therapy for pain palliation in metastatic bone cancer: a retrospective study
2019
ABSTRACTBone metastases are the most common sites for malignant tumors. Patients who failed to respond to initial first-line treatment with bisphosphonates usually suffer from extreme pain. The aim of this study was to observe the efficacy of arterial chemoembolization combined with Iodine-125 seed implantation in the treatment of bone metastatic cancer pain. All 14 patients with metastatic bone tumor wo failed first-line treatment underwent arterial chemoembolization the day before the implantation of the particles. A computer stereoscopic TPS was used to design the treatment plans, the number and dose of particles required for implantation. Pain relief was evaluated using several parameters such as Visual Analog Scale (VAS) and Verbal Rating Scales (VRS). Pain intensity was measured pre-operation and 1-week, 1-month, 3-month after the treatment. Meanwhile, we also assessed tumor size using computer tomography (CT). Pain palliation was observed in 35.7% (5/14), 57.1% (8/14), and 78.6% (11/14) of all pati...
