probability of such relapse. This is a very common situation in oncology – used for many early stage colon cancer
patients of whom there will be 143,000 in 2013 in US. This therapy is only partially effective since 52,000 patients will
die of metastatic colon cancer in 2013. Despite being used for decades, there is much room for improvement
