Accuracy of magnetic resonance imaging for prostate cancer: experience in changhua christian hospital

Purpose:

To evaluate the accuracy of MRI acquisition for staging of prostate cancer (PCa) in robot-assisted laparoscopic radical prostatectomy (RALAP).

Materials and Methods:

33 consecutive patients underwent a multiparametric MRI protocol prior to RALAP. Analyses were carried out to predict side-specific extracapsular extension using variables determined preoperatively, including 3.0-Tesla magnetic resonance imaging findings (T2-weighted and diffusion-weighted imaging). A prediction model was then constructed and applied to the validation study sample.

Results:

Of 33 eligible patients, histology showed ECE I in 14 (42%) cases. MRI sensitivity and specificity to detect ECE were 40 and 86%.

Conclusions:

MRI provides a high specificity and relatively low sensitivity for local staging of prostate cancer.
