Abstract：
Cancer pain is a frequent medical problem in our society. This syndrome affects from 80 to 90% of cancer patients and can be solved with relatively simple measures in 90% of the cases. Approximately 40% of cancer patients reported to be unsatisfied with the physician or nurse about their pain management. For these reasons, we gathered a task force in order to generate practice guidelines based on medical evidence and on the opinion of experts in this area. These guidelines were generated by a task force of 31 physicians who were leaders in this field and based on 599 papers selected by a previous literature search. This group evaluated the results of this search in three work sessions, during which a level of evidence was assigned to each recommendation.
