  • Descrição: To determine the sensitivity and specificity of clonal immunoglobulin heavy chain gene rearrangement (IGHR) analysis in the distinction of benign and malignant lymphoproliferative diseases. A retrospective analysis was conducted of patients in whom a malignant lymphoproliferative process was suspected. Cells of CSF samples were collected by centrifugation, resuspended in 100 μl of the supernatant and boiled. A 10 μl aliquot of this lysate served as template for semi-nested polymerase chain reaction using variable and joining region consensus primers. PCR products were analyzed by polyacrylamide gel electrophoresis. Cytopathological diagnosis and flow cytometry results were recorded. Sensitivity and specificity of IGHR analysis, cytopathology and flow cytometry were calculated. Eleven patients (12 specimens) had involvement of leptomeninges at the time of lumbar puncture. Another 25 cases (27 specimens) had normal CSF findings or were diagnosed...
