IDENTIFYING RESIDUAL AND RECURRENT DISEASE IN COLORECTAL CANCER (CRC) PATIENTS
Should you consider COLVERA™?
Every year there are approximately 140,000 newly diagnosed colorectal cancer cases in the United States. Following primary treatment, 30-50% of patients will see their cancer return, most of which will be within the first 2 – 3 years.1,2
Although, the risk of recurrence varies by stage at time of diagnosis, more treatment options may be available when recurrence is detected early.
Early detection of recurrent colorectal cancer allows for additional treatment options and improved patient care. That’s why we developed COLVERA, a simple blood test designed to help identify recurrent colorectal cancer early when more treatment options are available.
COLVERA can be ordered and performed with or without CEA during routinely scheduled follow up visits, and provides additional information to monitor care more confidently and to determine whether further testing should be considered.
How COLVERA works
When cancer grows, the tumor may shed small pieces of DNA into the blood stream, known as circulating tumor DNA (ctDNA). COLVERA can detect these small amounts of ctDNA containing changes often seen in colorectal cancer but not in normal blood.
Testing with COLVERA is quick and easy:
- Two tubes of blood are drawn
- Samples are sent to the Clinical Genomics laboratory
- The blood is processed using sensitive technology that analyzes changes to the genes associated with colorectal cancer
- Reliable results are provided to physicians within 7-12 days
COLVERA vs CEA
In a head to head clinical study, COLVERA detected twice as many recurrent colorectal cancer cases compared to CEA. Of 122 patients who were tested after completion of their initial treatment, 28 patients developed a recurrent disease confirmed by CT scan. COLVERA detected recurrence in 19 of the 28 patients compared to only 9 of 28 patients detected by CEA.1
