of 150 cases
C Rozman, E Montserrat, E Feliu, A Granena, P Marin, B Nomdedeu and JL Vives Corrons
A multivariate survival analysis by means of Cox's multiple regression
model was performed on a series of 150 consecutive patients with chronic
lymphocytic leukemia (CLL) from a single institution. In addition to the
well established prognostic factors, such as anemia and thrombocytopenia, a
marked prognostic value of the degree of absolute peripheral lymphocytosis
emerged from this analysis. This was evident in the whole population as
well as in low and intermediate risk groups of patients (Rai's stages 0, I,
and II and International Workshop on CLL stages A and B), pointing out that
different subsets of patients can be isolated within these groups.
