CANCER PAIN AND THERAPY

Abstract

Cancer pain is not a homogenous and clearly understood pathological process. The best treatment is a combination of drug and non-drug measures. Pain is divided into visceral, bone or neuropathic pain and has characteristics of continuous or intermittent pain. Cancer bone pain therapy remains centered on strong opioid, radiotherapy and bisphosphonates. Invasive procedures are aimed to improve neurological function, ambulation and pain relief. Solid tumors often demand surgery. Treatment of acute postoperative pain is crucial for the prevention of chronic pain. Chemotherapy and radiation sometimes also cause pain. The management of cancer pain has improved because of rapid diagnosis and treatment, understanding of analgesics and the cooperation of patients and their family. The presence of special pain centers in hospitals also raise standard of cancer pain management. Drug therapy with non-opioid, opioid and adjuvant drugs is the base of such management. The side effects must be monitored and timely treated. Methods of regional nerve blockade in pain control are numerous. Placement of epidural, intrathecal and subcutaneous catheters, conductive nerve blocks with continuous delivery of mixed local anesthetics are very successful for selected patients. Conventional physical therapy involving lymphatic drainage is useful. Acupuncture, psychotherapy and similar methods are also applicable.
