Could cancer cells be selectively targeted by using antibodies recognizing a tumor-specific protein marker? Researchers grafted human cancerous cells onto 20 healthy adult mice and then randomly assigned 10 of these mice to be treated with tumor-specific antibodies. They found that only 1 of the 10 mice treated with antibodies developed metastases (i.e., new cancer growths), whereas all 10 of the 10 mice in the control group developed metastases. Call (1) the treatment population (injected with antibodies) and (2) the reference population (untreated controls).
The relative risk reduction, RRR, in metastases development when treated with tumor-specific antigens compared with no treatment is ______________.
