Instead, they calculate the observed and expected number of failures at each time that a patient dies or is censored, and the result is more accurate—but even more computationally intensive—than the approach we used. The cBio Center in the Department of Biostatistics and Computational Biology has a three-fold mission: To provide oncologists with tools to mine genomic patient data for research and for guiding treatment decisions; to devise strategies to overcome resistance to targeted cancer drugs; and to create new connections between scientists at Dana-Farber and Harvard Medical School, including collaborative structures for scientists using quantitative sciences to solve biological problems.
