Use of multiparametric MR with neurovascular bundle evaluation to optimize the oncological and functional management of patients considered for nerve-sparing radical prostatectomy. | LitMetric

AI Article Synopsis

Article Abstract

Introduction: To obtain the best results with radical prostatectomy, either from an oncological or a functional point of view, a correct selection of cases and planning of surgery are crucial. Multiparametric magnetic resonance imaging (MRI) promises to make it a successful imaging tool for improving many aspects of prostate cancer management.

Aim: The aim of this study is to evaluate whether a modern multiparametric MRI can help either to better select prostate cancer cases for a nerve-sparing radical prostatectomy or to improve the functional evaluation related to neurovascular bundles preservation.

Main Outcome Measures: The effect of preoperative MRI on neurovascular bundle management was examined for the frequency and the appropriateness of changes of the surgical plane on the basis of MRI indications.

Methods: In a prospective study, 125 consecutive patients with biopsy proven prostate cancer who were scheduled to undergo bilateral nerve-sparing surgery. All patients included into the study were submitted to a preoperative multiparametric MRI. On the basis of MRI evaluation, patients were divided into two groups. Patients in group A were then submitted to a bilateral nerve-sparing (NS) radical prostatectomy (RP), whereas patients in group B were submitted to unilateral NS or non-NS RP.

Results: In group A, the confirmation from the MRI study to perform a bilateral NS procedure was appropriate in 70 of 73 cases (95.9%), whereas in group B, the surgical plan was appropriate in 28 of 32 cases (87.5%). On the contrary, MRI findings suggested a change in the initial surgical plan (group B) for 32 of 105 cases (30.5%). Of these 32 cases in group B, MRI suggested to perform a unilateral NS procedure in 21 of 32 cases (65.6%) and a non-NS procedure in 11 of 32 cases (34.4%).

Conclusions: Multiparametric MRI analysis can significantly improve the standard selection and management of prostate carcinoma cases considered for an NS RP.
