About this trial

There would appear to be a strong interest in functional nuclear imaging for assessing the response to focal PaC treatment. Investigator team hypothesise that the diagnostic performance of PSMA PET is noninferior to that of MRI in detecting clinically significant recurrent PaC after treatment with HIFU. The main objective was to evaluate the diagnostic performance of PSMA PET compared with MRI with reference to the gold standard of prostate biopsy one year after HIFU.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patient with prostate cancer

Age ≥ 70 years (HAS 2023)

Life expectancy > 5 years

Clinical stage Clinical stage T1c - T2a PSA < 20 ng/ml Biopsy :ISUP 2 unilateral on a maximum of 2 contiguous sextants with or without ipsilateral or contralateral focus ISUP1 single focus or multiple foci if only one ISUP 2 focus on targeted biopsy

Disqualifiers

Evidence of extra-prostatic extension or invasion of the seminal vesicles.

Any condition that, in the judgement of the investigators, would interfere with the subject's ability to

provide informed consent, comply with study instructions, expose the subject to increased risk, or interfere with the interpretation of study results.

Patients deprived of their liberty or under legal protection (curatorship and guardianship, safeguard of justice)

Trial outcomes

Primary outcomes

1

diagnostic performance of PSMA-PET

Measurement of the sensitivity and specificity of PSMA PET in the diagnosis of recurrence of significant prostate cancer one year after treatment with HIFU: the result will be considered positive (indicating a recurrence of prostate cancer) if the PSMA intensity score (SUV max) is 4.0 or higher; the presence of a recurrence of prostate cancer at the 1-year follow-up will be confirmed by biopsies (Gold Standard).

Time frame
12 months after treatment
