Prostate Cancer Risk Stratification

PRECISE scores for active surveillance

Prostate Cancer Radiological Estimation of Change in Sequential Evaluation (PRECISE)

PRECISE scores (1-5) definition:

1. Resolution of previous features suspicious on MRI

2. Reduction in volume and/or conspicuity of previous features suspicious on MRI

3. Stable MRI appearance: no new focal/diffuse lesions

4. Significant increase in size and/or conspicuity of features suspicious for prostate cancer

5. Definitive radiologic stage progression

PRECISE scores example:

1. Previously enhancing area no longer enhances

2. Reduction in size of previously seen lesion that remains suspicious for clinically significant disease

3. Either no suspicious features or all lesions stable in size and appearance

4. Lesion becomes visible on diffusion-weighted imaging; significant increase in size of previously seen lesion

5. Appearance of extracapsular extension, seminal vesicle involvement, lymph node involvement, or bone metastasis
