High MACC1 Levels Higher Risk for Metastasis

The researchers discovered the MACC1 gene by comparing tissue from healthy persons with tissue from 103 patients with colon cancer between 20 to 88 years of age. Sixty (60) cancer patients had no metastasis at the time they underwent surgery.

Of these 60 patients, 37 had no metastasis five years after surgery and treatment. These patients were shown to have had low levels of MACC1 when first diagnosed with colon cancer. In contrast, 23 patients had developed metastasis in the course of five years after surgery. Researchers detected high levels of MACC1 in their colon cancer tissue. Thus, patients with high MACC1 levels have a much higher risk for developing metastasis than patients with a MACC1 gene that is not very active.

The researchers are convinced that MACC1 will enable physicians to decide if a patient needs a more intense therapy or if a less aggressive treatment is sufficient. "The expression analysis of MACC1 in the original tumor tissue will probably contribute to individualize and optimize colon cancer therapy", they assume.

Now the MDC and Charite researchers and their colleagues want to find out if the MACC1 gene also allows for a more precise prediction about the outcome of lung cancer, breast cancer, and stomach cancer.
