Protein Predicting Cancer Metastasis is Identified

February 2, 2011: Experts from the National Institutes of Health and from Hong Kong university have identified a protein which is associated with the metastasis of cancer.

Screening of this protein in high levels in the tumors can predict the spread of cancer with 90 percent accuracy. The protein called CPE-delta N is a variant of the useful protein carboxypeptidase E (CPE) associated with the processing of insulin hormone.

Levels of the discovered protein were found to be more in the tumor cells and less in the cells surrounding the chunks of liver cancer. Experts believe that combining this knowledge with the presently available screening methods can be highly beneficial in preventing and treating metastasis on case-by-case basis.

Patients screened with tumors with high levels of CPE-delta protein can now be singled out and given intense cancer treatments in prior before the ailment is diagnosed to be in its advanced stage. This can raise the chances of successful treatment of many cancers and increase in the survival rates.
