[Pain problems in oncology].

1. Not every cancer patient suffers from pain, but approximately 30-40% of regular inpatients and 60-70% in terminal stages do. 2. Not every pain syndrome in a cancer patient is tumor-derived: its role and potential cause need to be thoroughly investigated and treated. 3. Successful antineoplastic treatment is the best and most durable pain prophylaxis in advanced cancer patients. 4. Locally applicable pain treatments such as anesthesiologic, radiotherapeutic and surgical measures should be discussed on an interdisciplinary basis. 5. With chronic tumor pain and no further effect of antineoplastic and locally active treatments, pharmacologic analgesia is the most adequate method of effective pain relief. 6. Prophylactic prescription of effective analgesics in adequate doses and at regular intervals, according to accepted "pain-ladders", is the most successful method of effective and lasting pain relief. 7. Public and medical bias against adequate use of oral opiates in chronic cancer pain must be overcome. 8. Effective pain relief leads to improvement of life quality as well as social reintegration of late stage cancer patients. 9. The influence of psychosocial variables on pain perception and the outcome of analgesia should not be underestimated.
