Brief summary

The aim of the study is to determine if PET-CT imaging (using contrast recommended in clinical guidelines) is superior to combined bone scan and MRI/CT of the abdomen & pelvis in detecting the increased incidence of metastasis (nodal/distant outside the pelvis) in men with prostatic carcinoma with mutations in any of the following germline DNA repair genes BRCA1, BRCA2, MSH2, MSH6, MLH1, PMS2, CHEK2, PALB2, ATM.

Interventions

Pt will undergo a PET-CT for their clinical treatment and we will review the images of this scan.

OTHERMRI pelvis or CT imaging under clinical management for Pr Ca

Individuals to undergo a clinical MRI or CT scan of Pelvis and the study reviews the images.

OTHERWhole body bone scan imaging

bone scan of the whole body (under clinical diagnosis).

Inclusion criteria

* Confirmed pathogenic germline mutation in any of the following genes BRCA1, BRCA2, MSH2, MSH6, MLH1, PMS2, CHEK2, PALB2 or ATM. * Over the age of 18 * Diagnosed with prostate cancer and at a time when staging imaging is clinically indicated; either: * At a new diagnosis * Biochemically progressing patients who were treated radically with surgery or radiotherapy (more than 6 months ago) and are currently not receiving hormonal treatment or chemotherapy * Patients on active surveillance with a PSA doubling time of 6 months or less

Exclusion criteria

* Diagnosis of other malignancy (excluding basal cell cancer/squamous cell cancer of the skin) within five years of diagnosis * Known metastatic prostate cancer, both local and distant * Patients who have received any oncological treatment within the last six months * Patients on any investigational drug treatment * Patients on steroids * Known history of inflammatory/infective diseases (e.g. sarcoidosis, tuberculosis, inflammatory bowel disease) * Contraindications to having an MRI using the standard MRI checklist (e.g. pacemakers, aneurysm clips, claustrophobia)

Design outcomes

Primary

MeasureTime frameDescription
1. Sensitivity of FCH-PET-CT scanWithin 12 months of the last FCH-PET-CT scanTo determine if the sensitivity of FCH-PET-CT is superior to combined conventional imaging (MRI (T2 and T1 weighted)/CT and bone scan) in detecting nodal and distant (outside the pelvis) metastases in BRCA1/2 germline mutation carriers with prostate cancer.

Secondary

MeasureTime frameDescription
2. Outline the Specificity of the FCH-PET-CT scanWithin 12 months of the last FCH-PET-CT scandetermining the positive predictive value (PPV) and negative predictive value (NPV) in detecting metastatic disease in BRCA mutation carriers with prostate cancer
Metastasis IncidenceWithin 12 months of the last FCH-PET-CT scan3.Incidence and sites of additional metastases identified on FCH-PET-CT compared with combined MRI/bone scan.
Impact of FCH-PET-CT findingsWithin 12 months of the last FCH-PET-CT scanTo measure the impact of FCH-PET-CT findings in changing patient management and in clinical decision making

Other

MeasureTime frameDescription
Incidental second primary tumoursWithin 12 months of the last FCH-PET-CT scanTo investigate the rate of incidentally detected second primary tumours in BRCA mutation carriers with prostate cancer
Prognostic significance of FCH-PET-CT findingsWithin 12 months of the last FCH-PET-CT scanTo investigate the prognostic significance of FCH-PET-CT findings (e.g. employing standard SUV parameters and heterogeneity of PET texture of the primary prostate tumour)
