[Treatment of breakthrough pain in cancer patients].

Pain is common in patients with cancer (33-64%) and can be divided into background and breakthrough pain (BTP). BTP is a passing, acute pain that occurs despite the use of analgesia to control background pain. BTP may arise spontaneously or be provoked by certain movements or activities. It lasts 30-60 minutes and is generally self-limiting and is often undertreated. We describe 2 patients aged 68 and 57 years with metastatic disease who were admitted for pain management. BTP was inadequately managed during their hospital stay. Both patients had to wait too long before they received their BTP medication, causing the BTP to have passed its peak. After consultation with their nurses, both patients were allowed to have one dose of breakthrough medication in advance, which resulted in better treatment of their BTP. Every hospitalized patient with BTP should have one dose of breakthrough medication ready for taking in advance.
