Chronic lymphocytic leukemia (CLL) is the most common adult form of leukemia in the Western world, however, infrequent in the Eastern. It shows a remarkable heterogeneity, with some patients having an almost normal lifespan, others surviving only several years after diagnosis despite intensive therapy. To investigate lipoprotein lipase (LPL) expression level in Chinese patients with CLL and its correlation with other prognostic factors, including immunoglobulin heavy-chain variable region (IgVH) mutation status, Binet stages, ZAP-70 protein and CD38 expression level, semiquantitative RT-PCR was used to detect LPL expression in peripheral blood samples of 58 Chinese patients with CLL. LPL expression level was significantly correlated with IgVH mutational status (r = 0.348, P = 0.010), Binet stages (r = 0.276, P = 0.036), ZAP-70 protein (r = 0.431, P = 0.001) and CD38 (r = 0.546, P < 0.001). Patients with unmutated IgVH genes had higher expression of LPL than patients with IgVH mutations. The higher expression level of LPL was also associated with higher level of ZAP-70 and CD38, and more aggressive Binet stage. We also analyzed LPL expression in different cytogenetic subgroups. Higher LPL level was found in patients with unfavorable cytogenetic aberrations (deletion in 17p13 or 11q22) in contrast to lower level in good risk cytogenetics (deletion in 13q as the sole abnormality) (r = 0.404, P = 0.002). It was showed that LPL expression correlates with IgVH mutational status and other clinical or laboratory prognostic factors, and might be applied for the assessment of prognosis in patients with CLL.
