Preparation of Patients with Prostate Cancer for Intensity Modulated Radiotherapy

Prostate Cancer for Radiotherapy

Purpose: To evaluate the efficacy of preparation of patients for intensity modulated radiotherapy (IMRT) for prostate cancer using a self-recorded sheet. Patients and Methods: A total of 106 patients underwent preparation for IMRT using a selfrecorded sheet. Patients noted stool condition, bowel movement time, medication for constipation, urinary frequency, and time of drinking of water. Before and after planning Computed Tomography (CT), patients visit our hospital several times for evaluation of bowel gas and stool using a treatment CT device (preparation CT) and the prescription was changed as necessary. After the start of IMRT, the rectum condition was evaluated by on board cone beam CT (CBCT) at every fraction. Medical staff entered “○” on the recording sheet when the rectum was empty in a preparation CT image or the prostate position could be adjusted by 3D-3D matching for each fraction. The “○” rates before the start of IMRT, during the first 14 days (F14) of IMRT, and in the first half (FH) and last half (LH) of the treatment period were compared for each patient
