The impact of demographic and disease-specific variables on pain in cancer patients.

The aim of this study was to examine to what extent demographic and disease-specific variables affected pain in cancer patients. Two to three weeks after their last hospitalization, 1,453 cancer patients completed questionnaires measuring demographic variables, quality of life, and pain (EORTC-QLQ C-30). Response rate was 72.1%. Data on type of cancer and the severity of the disease were also compiled. Sixty percent of the sample reported some pain. Type of cancer, presence of metastases, and time until death were significant predictors of experienced pain. The patients' experience of pain was mainly associated with disease-specific variables. Sex, age, level of education, and co-habitation were not related to pain, but employment status was. The patients on disability pensions had significantly more pain than the patients who were working or studying. Special attention should be given to patients with advanced prostate cancer with a short time to live, as they reported the most pain.
