    Several immunological markers were tested in 52 untreated cases of chronic lymphocyte leukemia (CLL) to see whether their frequency differed according to the clinical stage in Rai's system. The leukemic cells in all cases had B-cell features as shown by monoclonal immunoglobulins on the cell surface (SmIg) and/or a high percentage of mouse RBC (M)-rosettes. Of the two B-cell markers, the M-rosette test was the more consistently positive. The frequency of these markers did not correlate with clinical staging. The percentage of T-lymphocytes, low in all cases, was found to correlate inversely with the lymphocyte counts, which were higher in advanced stages. The absolute number of T-lymphocytes was above normal in most cases, but did not relat to staging. At least one of the serum Ig, most commonly IgA, was decreased in 87% of cases. Low Ig were slightly less common in Stages 0-I than in advanced stages (II-IV). The above features were also examined in two groups of CLL patients: with stable (9) or progressive (16) disease. The only difference observed between the two groups was that surface IgM only was present in 1 of the 9 stable cases as compared to 9 of the 16 progressive ones. Our findings do not support the suggestions that surface IgM is a feature of a benign form of CLL or that the absolute number of T-lymphocytes correlates with prognosis.
