Assessing Prognosis

The Goal of Prognostic Testing is to Predict Patient Outcomes

Myriad’s prognostic tests are designed to provide you and your patients with information about the aggressiveness of their cancer, allowing you to make better and more informed treatment decisions. Prognostic testing enables you to more effectively define a personalized treatment or monitoring strategy for each patient’s cancer.

Predicting Tumor Aggressiveness

No two cancers are the same, and it can be difficult to predict which tumors are slow-growing and which are likely to progress or metastasize. Prognostic tests that measure the expression of genes involved in cell cycle progression provide information that, when used in conjunction with other clinical features, can help predict disease outcome and guide treatment.

In Prostate Cancer

Managing localized prostate cancer presents a unique challenge because prostate cancer is highly variable and some tumors are slow-growing or nonaggressive. Monitoring tests such as prostate-specific antigen (PSA) level and Gleason score provide information on disease progression, but do not measure tumor aggressiveness. Understanding the aggressiveness of each patient’s specific prostate cancer can help you and your patient feel more confident about choosing the most appropriate treatment plan.*1,2 Prolaris® has been shown to effectively provide this information.

Myriad’s Prolaris Test

Prognostic tests such as Myriad’s Prolaris test for prostate cancer can provide accurate information about the aggressiveness of individual cancers.1,3. These tests analyze the expression of cell proliferation genes in the tumor to measure how fast the tumor cells are dividing. This information can be used along with other traditional clinical features of cancer progression to determine the risks associated with the patient’s disease, as well as personalize treatment decisions.*

In addition to Prolaris, Myriad is currently investigating prognostic tests for predicting the aggressiveness of other types of cancer.
