Substance abuse in cancer pain.

In the oncology community, opioids recently have become the cornerstone of cancer pain management. This has led to a rapid increase in opioid prescribing in an effort to address the growing public health problem of chronic pain. A new paradigm in noncancer pain management has emerged, that of risk assessment and stratification in opioid therapy. Techniques foreign to cancer pain management have now become commonplace in the noncancer pain setting, such as the use of monitoring compliance via urine drug screens. Amidst these strides in opioid use for pain management, cancer has been changing. The survival rate has increased, and a group of these patients with chronic pain were treated with opioid therapy. With opioid exposure being longer and against the backdrop of prescription drug abuse, the question is how much of the adaptation of the risk management paradigm in chronic pain management is to be imported to cancer pain management?
