The probability of resistance towards cyclophosphamide (C), doxorubicin, (H), vincristine (O), and rituximab (R) determined by applying the REGS classification (Dybkaer et al. [18] and Laursen et al. [19] in preparation) onto .CEL files from Affymetrix U133plus2.0 arrays of the indicated samples through http://www.hemaclass.org. A probability close to 1 predicts resistance, whereas a value close to 0, predicts sensitivity to the indicated drug
