MRC CLL3
Study hypothesis
To establish whether the addition of epirubicin to standard chlorambucil therapy prolongs the duration of remission and survival, to evaluate the therapeutic benefit of anthracyclines in CLL by comparing the objective response rate to chlorambucil alone with that to chlorambucil + epirubicin, to assess the relative toxicities of two regimens.
