Lower urinary tract symptoms in patients with prostate cancer under and after intensity-modulated radiation therapy.

Abstract

The aim of the present study was to collect data on the characteristics, degree, and natural course of urinary complications, as well as self-care for such complications, in patients during and after prostate intensity-modulated radiation therapy (IMRT). Quality of life data were collected retrospectively for all eligible patients who underwent IMRT. In all eligible patients, urinary symptoms were evaluated using questionnaires and face-to-face interview. Participants were asked to respond to a self-administered questionnaire concerning the core lower urinary tract symptom score during the course of IMRT and up to 12 months after the completion of IMRT. In all, 29 eligible patients were included in the study. The frequency of urinary symptoms increased over of the course of IMRT, decreased at ≥3 months after completion of IMRT, and disappeared 6 months after IMRT. Responses to the questionnaire revealed a variety of approaches to self-care and adaptations by patients to manage urinary symptoms. During and after IMRT for localized prostate cancer, patients often developed more frequent urination and urgency than at the start of IMRT, and recovered 3-6 months after the completion of IMRT. Based on the present study, clinicians and nurses could help convey this information to patients and thus offer better support.
