3-T multiparametric MRI characteristics of prostate cancer patients suspicious for biochemical recurrence after primary focal cryosurgery (hemiablation)

Abstract

Post-PFC mpMRI, at Phoenix suspicion of BCR, may help identify a significant number of patients failing post-PFC.

Use of MRI-Guided Biopsy for Selection and Follow-up of Men Undergoing Hemi-gland Cryoablation of Prostate Cancer

“…Thus, disappearance of an MRI-visible lesion was associated with the treatment, but did not specifically indicate eradication of cancer. In a retrospective study with limited biopsy correlations, Kongyuy et al reported a similar observation 28 . The role of MRI in evaluating response to treatment remains a subject for further investigation.…”

“…PSA level among these studies ranged from 0.02 to 123, with a mean value from 5.9 to 12.24 ng/mL. Only 4 studies reported the data of prostate volume, in spite of the fact that some studies suggested it is possible to play a part in the diagnosis 17,18,21,32. Five studies performed the MRI with 1.5T scanners17,18,21,23,28 and the remaining 13 studies used 3.0T scanners 2,4,10,19,20,22,24,25,27,29–32.…”

Except 5 studies,2,23,24,27,29,31 all of the others were used at least one type of endorectal, pelvic phased array (PPA), or body coil; moreover, 2 studies used two types of them (endorectal coil and PPA) 28,30.…”

“…ADC values obtained from DWI protocol were 0/50/100/400/500/800/1,000/1,500 and 2,000 s/mm 2 , but most studies only used 2–3 values of them. Sixteen studies reported the specific ADC values, whereas the remaining 2 study did not give further details 23,32…”

“…There was a high risk of bias in 9 studies regarding index test domain. Five of 9 studies did not report whether the readers were blinded to the reference test results 4,17,21,31,32. Regarding the other 4 studies, readers were aware of the PSA level or/and GS of patients, though they were blinded to the histopathological findings 20,23,25,30.…”
