Opioids remain an important cornerstone in the treatment of cancer pain. Effective analgesia is obtained in the majority of cancer pain patients with the application of fairly straightforward algorithms using opioids as the main therapy. Many rational treatment algorithms exist. In this tutorial we will describe the role of opioids in the treatment of cancer pain, including a brief overview of cancer pain syndromes, essential aspects of opioid therapy, opioid pharmacology, opioid rotation, properties of the individual opioids, and management of common side effects of opioids.

A 48-year-old man developed ischemic pain of the hands while undergoing cisplatin and gemcitabine chemotherapy for metastatic pancreatic carcinoma. After extensive pharmacologic management and surgical sympathectomy failed to provide adequate analgesia, the patient underwent a percutaneous spinal cord stimulation trial followed by permanent implantation and received significant pain relief prior to succumbing to his illness. Spinal cord stimulation provided effective therapy for refractory ischemic pain, even after failed sympathectomy.

7610 Background: Painful vertebral compression fractures are a major source of morbidity in MM. Vertebroplasty involves percutaneous injection of polymethylmethacrylate (PMMA) into a vertebral body, while kyphoplasty involves inflation of a balloon for painful kyphotic deformity prior to stabilization with PMMA. Methods: We assessed safety and efficacy of 100 vertebroplasties and/or kyphoplasties in 81 consecutive myeloma patients between 12/2000 and 2/2005. Results: Median age was 63 (range 32–84), with 29% having prior radiotherapy to the vertebra treated. Contraindications included epidural compression of neural elements and failure to localize a symptomatic level. Kyphoplasty was preferred if kyphosis of > 20 degrees contributed to pain, or if the posterior vertebral cortex was disrupted so that controlled delivery of bone cement was difficult. Vertebroplasty was performed when vertebral collapse was either slight or so severe that insertion of balloon device was not possible, or if patient could not tolerate the general anesthesia required for kyphoplasty. The median preoperative visual analog pain score (0–10) was 8(range 2–10); the median postoperative pain score was 3 (range 0–10) (p < 0.01). There were no significant complications . Conclusions: Percutaneous vertebroplasty and kyphoplasty provided rapid and marked pain relief. These procedures are safe and feasible and represent the treatment of choice in selected MM patients with severe refractory pain due to pathologic compression fractures.
