Oncotype DX Colon Recurrence Score® test

The Oncotype DX Colon Recurrence Score test is clinically validated to quantify the risk of recurrence of patients with anatomic stage II, T3 or T4, MMR-P, or stage III A/B colon cancers. This 12-gene test—with 7 cancer-related genes and 5 reference genes—looks at the underlying biology of a patient’s tumor, so you can choose a treatment that fits their unique situation.1-4

Gain foresight using genomic insights

The Colon Recurrence Score® test results provide a precise estimate of the risk of recurrence for anatomic stage II, MMR-P, or stage III A/B patients to help guide the most appropriate treatment decision.1-4

High Recurrence Score® Result

Identifies anatomic stage II MMR-P patients at higher risk of recurrence.1-4

These patients may have a larger absolute benefit from chemotherapy

Low Recurrence Score Result

Identifies anatomic stage III A/B patients at lower-than-average risk of recurrence.3,4

These patients may have a smaller absolute benefit from the addition of oxaliplatin to fluorouracil and leucovorin (5-FU/LV).

For your Stage II MMR-Proficient, T3 or T4, and Stage III A/B colon cancer patients, it’s time to consider the Colon Recurrence Score test.

A genomic test for colon cancer with level 1 evidence

The Colon Recurrence Score test is backed by data developed over the course of multiple collaborative studies with both anatomic stage II and stage III patients.

Four validation studies—QUASAR, CALGB 9581, NSABP C-07, and SUNRISE—confirm that the Colon Recurrence Score test result predicts the risk of local recurrence.1-4 In addition, studies show that physicians often change treatment recommendations based on the test results.5-8

Genes that provide real insights into colon cancer tumor biology

The Colon Recurrence Score test was developed in 4 steps resulting in a 12-gene panel and algorithm that’s been validated in several studies.1-4,9-11

Optimization of methods for quantifying gene expression in formalin-fixed, paraffin-embedded tissue (FPET).

Selection of 761 candidate genes from the human genome.
