Pain prevalence at various stages of cancer ranges from 27% to 60% for outpatients. Yet, how pain is managed in this patient group is poorly understood. ⋯ Pain remains a significant problem in medical oncology outpatients, and often pain is insufficiently managed. Patients with a high pain intensity were more at risk to experience pain related interference with daily activities, but even some patients suffering mild pain experienced this. As adequate pain relief for up to 86% of the patients with cancer should be feasible, pain in medical oncology outpatients is still undertreated. Taking into account the interference of pain with daily activities and predictors of pain will facilitate cancer pain management. The study has been approved by the Medical Ethics Committee (CMO) in all 7 hospitals (METC protocol number 2011/020) and has been registered by the Dutch Trial register (NTR): NTR2739.

The high prevalence of persistent low back pain and growing number of diagnostic and therapeutic modalities employed to manage chronic low back pain and the subsequent impact on society and the economy continue to hold sway over health care policy. Among the multiple causes responsible for chronic low back pain, the contributions of the sacroiliac joint have been a subject of debate albeit a paucity of research. At present, there are no definitive conservative, interventional or surgical management options for managing sacroiliac joint pain. It has been shown that the increases were highest for facet joint interventions and sacroiliac joint blocks with an increase of 310% per 100,000 Medicare beneficiaries from 2000 to 2011. There has not been a systematic assessment of the utilization and growth patterns of sacroiliac joint injections. ⋯ This study illustrates the explosive growth of sacroiliac joint injections even more than facet joint interventions. Furthermore, certain groups of providers showed substantial increases. Overall, increases from 2008 to 2010 were nominal with 1%, but some states showed over 20% increases whereas some others showed over 20% decreases.

Discogenic pain is an important cause of low back pain (LBP). We have developed a pulsed radiofrequency (PRF) technique, using Diskit II needles (NeuroTherm, Middleton, MA, USA) placed centrally in the disk, for applying radiofrequency current in the disc (Intradiscal PRF method). ⋯ This intradiscal PRF method with consecutive PRF 5/5/60V, 15 min (with Diskit needle) appears to be a safe, minimally invasive treatment option for patients with chronic discogenic LBP.

Vertebral metastases are associated with significant pain, disability, and morbidity. Open surgery for fracture stabilization is often inappropriate in this cancer population due to a poor risk-benefit profile, particularly if life expectancy is short. Vertebroplasty and kyphoplasty are appealing adjunctive procedures in patients with malignancy for alleviation of intractable pain. However, these patients have a higher risk of serious complications, notably cement extravasation. ⋯ The Kiva System potentially represents a novel and effective minimally invasive treatment option for patients suffering from severe pain due to osteolytic vertebral metastases.
