Multi-gene Expression Assay for Predicting Recurrence in Colon Cancer

Does Not Apply to Commercial Genetic Testing Program effective 6/1/2018

DESCRIPTION

Multi-gene expression assays are proposed for use as prognostic markers in stage II or stage III colon cancer to identify individuals who are at high risk for recurrent disease and those who could be candidates for adjuvant chemotherapy. The majority of individuals with stage II colon cancer (75%-80%) are cured by surgery alone, and the absolute benefit of chemotherapy for the overall population is small. Individuals most likely to benefit from chemotherapy are difficult to identify by standard clinical and pathologic risk factors. Genomic tests are proposed to facilitate the identification of those individuals. For individuals with stage III colon cancer, the current standard treatment includes six months of adjuvant chemotherapy after primary surgical treatment.

Currently there are several multi-gene expression assays being marketed for clinical use in the United States.

ColoPrint® (Agendia) 18-gene Colon Cancer Recurrence Assay
GeneFx™ (Helomics) 634 probe set (482 gene) signature
OncoDefender-CRC™ (Everist Genomics) 5-gene test
Oncotype DX® Colon Cancer Assay (Genomic Health) 12-gene expression test

POLICY

IMPORTANT REMINDERS

ADDITIONAL INFORMATION 

Current evidence is insufficient to permit conclusions on how gene expression classification compares with other approaches for identifying recurrence in individuals with stage II or III colon cancer. Studies showing management changes as a consequence of testing do not demonstrate whether such changes improve outcomes. The evidence is insufficient to determine the effects of the technology on health outcomes.
