Purpose Of Review:
Multiparametric MRI (mpMRI) has been included in the diagnostic pathway of prostate cancer (PCa). However, the role of this imaging modality in predicting clinical outcomes after diagnosis has been poorly addressed so far. This review aims to summarize the most relevant updates on the prognostic role of mpMRI.
Recent Findings:
Baseline mpMRI features help to predict adverse pathology at radical prostatectomy (RP) and grade reclassification during active surveillance. Parameters derived at prostate mpMRI such as PI-RADS score 4-5, the maximum diameter of the index lesion and the presence of extracapsular invasion/seminal vesicle invasion are among the strongest predictors of biochemical recurrence (BCR) for men treated with RP. mpMRI-based predictive models can achieve similar accuracy for BCR prediction when compared with validated models that relied on final pathology. Moreover, the use of mpMRI findings to predict disease recurrence after radiotherapy or focal therapy seems to optimize patient's risk stratification after treatment, ruling out disease recurrence.
Summary:
Clinicians should account for prostate mpMRI findings when predicting clinical outcomes in patients diagnosed with PCa.
Insights
Multiparametric MRI (mpMRI) aids in predicting prostate cancer (PCa) outcomes. mpMRI findings help forecast disease recurrence and adverse pathology, guiding clinical decisions post-diagnosis.
Area of Science:
- Radiology
- Oncology
- Medical Imaging
Background:
- Multiparametric MRI (mpMRI) is integral to prostate cancer (PCa) diagnosis.
- The prognostic value of mpMRI in predicting clinical outcomes post-diagnosis requires further elucidation.
Purpose of the Study:
- To review current literature on the prognostic role of mpMRI in PCa.
- To summarize updates on how mpMRI predicts clinical outcomes after PCa diagnosis.
Main Methods:
- Literature review of studies investigating mpMRI for PCa prognosis.
- Analysis of mpMRI parameters and their correlation with clinical outcomes.
Main Results:
- Baseline mpMRI predicts adverse pathology and grade reclassification.
- mpMRI features (PI-RADS 4-5, index lesion size, invasion) strongly predict biochemical recurrence (BCR) post-radical prostatectomy.
- mpMRI-based models show accuracy comparable to pathology-based models for BCR prediction and aid in risk stratification after radiotherapy or focal therapy.
Conclusions:
- Prostate mpMRI findings are crucial for predicting clinical outcomes in PCa patients.
- Clinicians should integrate mpMRI data into prognostic assessments for informed patient management.
