Of 43 patients eligible for analysis, observations were made in 42.
The LDH value was not available at diagnosis in one patient
The amount of BCL2/IgH+ cells in the BM was defined as being high, when more than one positive cell was detected among 100 normal cells; intermediate, when 1 positive cell was detected among 100 to 1000 normal cells; or low, when 1 positive cell in was detected among 1000 to 100 000 normal cells
