Objective To collect data on pain management in paediatric oncology with respect to the WHO ladder approach. Setting, design, patients and methods Eight German tertiary care paediatric oncology centres prospectively documented all their in‐patient pain treatment courses from June 1999 to December 2000. Pain was scored using a 1–6 faces scale. Results Two hundred and twenty four patients (median age, 9 years; range 0.2‐32.1) were enrolled. Three hundred and thirty three pain episodes comprising a total of 2265 treatment days were documented. Pain was mostly therapy associated. The most frequently administered non‐opioid analgesics were dipyrone and paracetamol. On WHO step 2, tramadol was almost the only opioid used. During tramadol monotherapy average daily pain scores were lower than with a combination of tramadol and non‐opioid analgesics. On WHO step 3, morphine was at least part of the analgesic regimen on most treatment days. Strong opioids were combined with a non‐opioid analgesic on 41% of the treatment days. The mean intravenous morphine equivalence dose was 0.034 mg/kg/h. During opioid and non‐opioid combination therapy, adverse effects were more frequent, and average pain scored higher than on opioid monotherapy. Conclusions WHO‐guidelines were closely followed in Germany and seem to provide effective analgesia for children with cancer pain. In our patient group there is no evidence that a combination of an opioid with a non‐opioid is more effective than opioid therapy alone in in‐patient paediatric oncology pain treatment.
