 The parameter for the comparison of R-FC and R-CHOP will be the percentage of complete remissions after initial cytoreductive therapy. According to the known results of R-FC and R-CHOP in lymphoma therapy, a relevant difference between R-CHOP and R-FC in the overall response rates is not expected. For both therapies an overall response rate of about 90 is expected. Since it is well known that the prognosis of patients who do not reach at least a PR in the initial therapy is very poor, it will be also necessary to control this parameter during the study. If an unexpected relevant difference in the overall response rates is observed during the study, the initial randomisation should be stopped and all patients should be assigned to the superior therapy. In this case the CR rates will not be important for the choice of the initial therapy. If no relevant differences in the overall response rates are observed, a one sided Fisher test will be performed at the end of the recruitment to test whether the rate of CRs after R-FC is significantly improved compared to R-CHOP.
