Prostate Cancer Clinical Trial
Official title:
Image-guided Focal Brachytherapy Utilizing Combined 18F-DCFPyl PET/CT and Dynamic Dosimetry With Registered Ultrasound and Fluoroscopy for Localized Prostate Cancer
The Principal Investigator's (PI) working hypothesis is that the PI can utilize the high predictive value of 18F-DCFPyl PSMA to identify clinically significant tumors in patients who will undergo brachytherapy, as well as areas which are uninvolved or contain only clinically insignificant disease. In the PI's clinical trial, the uninvolved regions (as defined by combined PET-MR-biopsy data) will not be targeted and receive only fall-off dose, which we have shown to be associated with reductions in toxicity.

Primary | Percent tumor coverage | Percent coverage of the combined PET-MR based tumor volume achieved when using iRUF intraoperative dosimetry. PET-MR tumor volume D90 will be defined on pre-treatment PET-MR fusion, and dose from seeds will be calculated on post-implant MR/CT (Day ~30); the two volumes will be co-registered to determine tumor volume coverage. |
