Quality of life in a population of Polish patients with prostate cancer.

INTRODUCTION Recent advances in treatment have led to the prolongation of life among patients with prostate cancer (PCa), which implies greater interest in the issue of the quality of life (QoL) in patients who undergo treatment. The quality of life of patients with cancer questionnaire (QLQ-C30) and the quality of life questionnaire specific to PCa (QLQ-PR25) are tools used worldwide to conduct research on this subject. In our study we assessed the quality of life in a population of Polish patients suffering from prostate cancer. Differences in the quality of life depending on the stage of the disease were highlighted. MATERIAL AND METHODS We conducted a prospective, multicenter, observational study using the QLQ-C30 and QLQ-PR25 questionnaires in a group of 1047 patients. RESULTS The highest QoL scores (according to the QLQ-C30 questionnaire) were observed in patients with localized prostate cancer, while the lowest were recorded in the metastatic group. Sexual activity and sexual functioning assessed on the basis of QLQ-PR25 was best in the group of patients suffering from localized prostate cancer, and the worst in patients with locally advanced PCa. CONCLUSIONS The assessment of QoL showed a significant correlation with the stage of the disease. Sexual activity and sexual functioning were the best in patients with localized cancer; worst among patients with locally advanced tumor.
