SYMPTOMATIC PAIN TREATMENT IN ADVANCED BREAST-CANCER

From 1983-1989, 106 patients with breast cancer were treated in our pain management unit on 6767 treatment days. Pain was caused by bone metastasis in 73 % of patients. Neuropathic pain was reported by 32 % of the patients. In all but four of these patients, new tumour growth was diagnosed. Patients were treated according to WHO analgesic guidelines with non-opioids on 16 % of the days, non-opioids in combination with weak opioids on 36 % and with strong opioids on 38 % (orally 90 %, parenterally 4 % of the days). Due to the prevalence of bone pain non-steroidal antiinflammatory drugs were given on 56 % of the days. The high incidence of neuropathic pain led to frequent use of co-analgesics (antidepressants 17 %, anticonvulsants 12 %, steroids 12 % of the days). Adjuvant therapy for symptoms other than pain was given on 86 % of the days. Whilst 92 % of patients reported more than moderate pain on admission, 45 % obtained complete pain relief beginning from the first days of treatment. On 92 % of the days, patients described their pain as moderate or less. Side effects were treated symptomatically and played a minor role in a reason to change therapy.
