[Basics of drug therapy of cancer pain].

Industrial countries experience a significant increase of cancer prevalence. Despite recent advances in the treatment of various types of cancer still most of the patients cannot be cured. Especially the advanced incurable stages of cancer, however, often are accompanied by severe pain. Therefore, the high demand for a sufficient pain management and symptom control seems obvious. Throughout the last decades new drugs and techniques for the management of cancer pain have been developed. Most cancer patients should experience sufficient pain-management if existing recommendations for the pharmacological treatment of cancer pain (e.g. WHO-guidelines) are followed consequently. If, nevertheless, intractable pain or ongoing disabling symptoms continue despite proper therapy, every doctor should feel himself obliged to consult an expert in palliative medicine, in order not to tolerate avoidable suffering of his patient.
