Bowel and Bladder Reproducibility in Image Guided Radiation Therapy for Prostate Cancer: Results of a Patterns of Practice Survey

Predictors for late genitourinary toxicity in men receiving radiotherapy for high-risk prostate cancer using planned and accumulated dose

“…The dose range received by bladder V 75 Gy for D A and D P is well below our departmental planning dose constraint of ≤ 25 % [49] . Therefore, keeping within this dose limit, in addition to an acceptable bladder filling protocol and a robust image-guided RT workflow while performing dose escalation is highly recommended [11] , [50] . Another point worth mentioning will be the higher D A at the intermediate to high dose region ( and ).…”

Stereotactic Body Radiation Therapy in Prostate Cancer: Where Do We Stand?

“…48,49 Before contouring, it is necessary to prepare the bowel and bladder before simulation, and patients may be administered enema/stool softeners before simulation to keep the rectum as empty as possible. 50 The bladder is moderately filled by asking the patient to first empty their bladder and then consume water (500 mL), and the CT/MR images are acquired 45 min after; patients are advised to follow the same protocol during RT days. Foley's catheter may be used to visualize and delineate the urethra.…”

A Single-Institution Prospective Study to Evaluate the Safety and Efficacy of Real-Time-Image Gated Spot-Scanning Proton Therapy (RGPT) for Prostate Cancer

“…The current usage of internal and setup margins for conventionally fractionated prostate radiation therapy is reported as 6 mm (range, 3-10 mm; except posteriorly 5 mm; range, 0-8 mm), 22 but relatively small margins of 3 to 5 mm are used for IMPT. 23,24 In addition, it is necessary to consider the beam range uncertainty in PBT, and margin recipes of 2.5% to 3.5% of the range plus an additional 1 to 3 mm have been reported.…”
