Cancer pain: a review of epidemiology, clinical quality and value impact.

Cancer-related pain, reported by more than 70% of patients, is one of the most common and troublesome symptoms affecting patients with cancer. Despite the availability of effective treatments, cancer-related pain may be inadequately controlled in up to 50% of patients. With the growing focus on 'value' (healthcare outcomes achieved per dollar spent) in healthcare, the management of cancer-related pain has assumed novel significance in recent years. Data from initiatives that assess the quality of pain management in clinical practice have shown that effective management of cancer-related pain improves patient-perceived value of cancer treatment. As a result, assessment and effective management of cancer-related pain are now recognized as important measures of value in cancer care.
