Pain is one of the most feared and burdensome symptoms experienced by cancer patients. Its prevalence has been estimated by INCa1 in 2012 at 48% in patients undergoing cancer treatment, and unrelieved pain is directly associated with significantly reduced quality of life (QoL)2. A large part of cancer pain undertreatment can be attributed to patient-related barriers. Patient barriers are multifactorial and often result from a lack of knowledge about cancer pain and its self-management. They mainly consist of misconceptions about opioids and their side effects, nonadherence, and reluctance to alert health care providers to unrelieved pain. Patient education enables people with chronic disease to manage their illness, and has been considered in the field of cancer research as an important strategy to achieve optimal pain control.

In Basse-Normandie french region, the "Health Regional Plan, pain aspect" has identified the theme " pain education program " as a priority.

The main endpoint is the decrease of pain interference with daily life (using the Brief Pain Inventory). The experimental group, consisting of cancer pain patients, will benefit from the education program by previously trained health care providers. It will be compared with the control group, consisting with patients whose pain will be conventionally managed before the professional training in therapeutic education.
