To introduce new parameters of diploid histogram of image DNA cytometry and new types of silver-stained nucleolar organizer regions (AgNORs) and to validate resulting proliferative-kinetic index (PKI) in a prognostic study of patients with chronic leukemic lymphoproliferative disorders (CLLPD).A total of 413 smears of from various tumor mass compartments-bone marrow, peripheral blood and lymph node-were analyzed in CLLPD as a whole, as well as separately in the B-chronic lymphocytic leukemia with variants (B-CLL+V). The analysis of the diploid histogram included percentage of cells at the peak of the DNA histogram and percentage of cells with lower and higher contents of DNA than cells at the peak. The new types of AgNORs were described as homogeneous, inhomogeneous and annular.The newly introduced parameters of DNA and AgNOR are significant predictors of survival. Based on the most representative AgNOR and DNA characteristics related to survival, the PKI score was calculated. The CLLPD and B-CLL+V patients had a statistically significantly better prognosis when PKI was4.PKIs have confirmed the hypothesis that different prognostic subgroups could be identified within the homogeneous groups of neoplasms with relatively low malignancy (CLLPD and B-CLL+V). |
