Safely manage patients conservatively.

“The [cell cycle progression] score provides significant pretreatment prognostic information that cannot be provided by clinical variables and is useful for determining which patients can be safely managed conservatively, avoiding radical treatment.”

Strongest independent predictor of cancer death outcome.

“For conservatively managed patients, the [cell-cycle progression] score is the strongest independent predictor of cancer death outcome yet described and may prove valuable in managing clinically localised prostate cancer.”

Prolaris added significantly to prediction of BCR in multivariate analysis, both in overall cohort and subset of men meeting NCCN low risk criteria.

“In a cohort of NCCN low-risk patients, the CCP score improved clinical risk stratification of patients at increased risk of BCR [biochemical recurrence], which suggests the CCP score could improve the assessment of candidacy for active surveillance and guide optimal treatment selection in these patients with otherwise similar clinical parameters.”

Prolaris predictor of metastatic disease, with no difference in predictive performance between races or treatment groups.

“Contrary to expectation, this study provides no evidence that African American men have more aggressive disease than non-African American men after accounting for all available molecular and clinicopatholgic prognostic information.”

Identify men likely to benefit from radiation after BCR.

“Among patients treated by radical prostatectomy who develop [biochemical recurrence], [cell cycle progression] score may predict systemic disease and could be used to help guide subsequent therapeutic interventions.”
