Patients with cancer frequently experience chronic pain, especially in the terminal phases of illness. Fortunately, most patients (90%) can achieve good pain relief using standard and adjuvant analgesics. For those patients who experience severe pain resistant to traditional analgesic therapies, interventional pain management techniques often provide welcome pain relief. ⋯ The percutaneous placement of catheters for the chronic infusion of spinal analgesics can provide pain relief for virtually any part of the body. Internal or external infusion pumps can be well managed at home, improving quality of life. The physician treating the pain should be aware of these and other interventional pain management techniques to provide alternative therapies to patients with refractory cancer pain.

Review Comparative Study
Meeting the challenges in cancer pain management.
Improved life expectancy among patients with cancer has unfortunately resulted in significant increases in the number of patients experiencing chronic, intractable pain-neuropathic pain syndromes, in particular. Yet treatment for this pain is frequently suboptimal. This is due, at least partially, to the generalized nature of available therapeutics, which are often aimed toward symptom management and temporal pain properties rather than targeted directly toward the multiple mechanisms underlying the generation and propagation of pain. ⋯ However, in oncology perhaps more than in any other field, pain is dynamic and ever-changing in response to a variety of factors, including chemotherapeutic, radiation, or surgical interventions. For this reason, patient-specific assessment and continual monitoring are warranted when selecting a therapeutic regimen. General considerations, particularly when an opioid agent is utilized, should include pharmacoclinical, pharmacoeconomic, and pharmacogenetic variables.

Relief of cancer-related symptoms is essential in the supportive and palliative care of cancer patients. Complementary therapies such as acupuncture, mind-body techniques, and massage therapy can help when conventional treatment does not bring satisfactory relief or causes undesirable side effects. Controlled clinical trials show that acupuncture and hypnotherapy can reduce pain and nausea. ⋯ Pilot studies suggest that complementary therapies may treat xerostomia, hot flashes, and fatigue. Botanicals or dietary supplements are popular but often problematic. Concurrent use of herbal products with mainstream medical treatment should be discouraged.
