[Stage classification of chronic lymphatic leukemia. A retrospective analysis of 263 cases]. / La classificazione in stadi della leucemia linfatica cronica. Analisi retrospettiva di 263 casi.

We have analyzed 263 consecutive patients with chronic-lymphocytic leukemia. They all have been studied according to five different staging systems respectively proposed by Rai (1975), Binet (1977), Binet again (1981), Baccarini (1982) and Rozman (1984). All these procedures proved to be effective, because they divided our cases in groups with significant differences in survival time. The paper displays features and usefulness of each staging system.
