Radiology: Application of multi-parameter MRI in preoperative prediction of extraprostatic invasion

Extraprostatic invasion (EPE) is associated with positive surgical margins, local recurrence and survival rate after radical resection of male prostate cancer
.
Since the existence of EPE can affect the preservation of neurovascular bundles during surgery, the preoperative prediction of EPE is of great significance

Extraprostatic invasion (EPE) is associated with positive surgical margins, local recurrence and survival rate after radical resection of male prostate cancer

Recently, a new MRI grading system for predicting EPE has been proposed clinically, called EPE grading

In order to reduce the resection margin rate of positive surgical resection, the focus on multi-parameter MRI performance should turn to high sensitivity rather than high specificity.

Recently, a study published in the journal Radiology compared classification, European Society of Urology and Reproductive Society (ESUR) score, Likert scale, and capsular contact length (CCL) to evaluate and predict the diagnosis of EPE after radical resection of prostate cancer.

A total of 301 male patients (mean age ± standard deviation, 65 years ± 7 years) were evaluated
.
A total of 129 patients (42.

9%) had EPE

Compared with the EPE score , the Likert scale is less sensitive.

The horizontal line in each box represents the middle value

In summary, this study verified and compared four methods for detecting extraprostatic invasion (EPE) on multi-parameter MRI
