Multi-modality Prostate Cancer Image Guided Interventions (IGPC-2)

February 26, 2024 updated by: Lawson Health Research Institute
This is a non-randomized, prospective trial of men who are scheduled for radical prostatectomy for treatment of prostate cancer, or repeat biopsy for localized prostate cancer as standard of care and who will undergo a series of pre-operative multi-modality imaging studies. Post intervention, hybrid imaging maps (HIM) will be generated and the predictions of the HIM (3D location, volume and grade of cancer) will be correlated with actual pathology results to gauge the performance of the HIM in both radical prostatectomy and biopsy settings.

Detailed Description

This study was built on our first study (IGPC-1, REB number 15551) which acquired multi-modality imaging in 36 patients undergoing radical prostatectomy. We successfully demonstrated the ability to accurately co-register pre-operative multi-modality images (MRI: T1, T2, Diffusion Weighed (DW), Dynamic Contrast enhanced (DCE); Dynamic Contrast Enhanced CT, 3D Ultrasound with post-operative whole mount pathology specimens. We have developed a platform for the segmentation of prostate cancer on the whole mount pathology specimens and are in the process of analyzing the data to develop a hybrid imaging map (HIM) of prostate cancer distribution (location and grade) based on the correlation of the pre-operative imaging signals and the post-operative pathology (citation provided below). The HIM will need subsequent validation in a separate cohort of radical prostatectomy patients and evaluated as to its ability to be incorporated as a targeting tool for prostate interventions such as prostate biopsy and this is the purpose of this follow-up study.

On the IGPC-2 study, pre-operative imaging panels were successfully obtained in 24 patients accrued to cohort 1. The protocol was then amended to include [18-F]-DCFPyl instead of [18F]-FCH. [18-F]-DCFPyl was a newer PET probe that may possess superior performance because it is directed against prostate specific membrane antigen (PSMA), a protein commonly expressed on prostate cancer cells. Imaging-pathology correlations in the first 6 patients imaged with [18-F]-DCFPyl were compared to the correlations obtained with [18F]-FCH imaging in the first 24 patients.

IGPC-2 Cohort 1 (Radical Prostatectomy) was expanded to provide an additional 20 men imaged with [18-F]-DCFPyl as part of the imaging panel. The goal was to acquire 24 complete imaging datasets with [18-F]-DCFPyl as the PET imaging agent to enable us to draw comparisons with the 24 [18F]-FCH imaging data sets acquired.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
