ANALYSIS OF CELLULAR IMMUNE MARKERS IN CEREBROSPINAL FLUID OF LYMPHOMA PATIENTS AT THE HEMATOLOGY CENTER - BACH MAI HOSPITAL
Main Article Content
Abstract
Objectives: Determination of the diagnostic value of central nervous system invasive lymphoma by flow cytometry compared with cytogenetic methods. Participants and Methods: Cross-sectional description of 33 patients with lymphoma or 6 suspected lymphoma patients with neurological manifestations who underwent cerebrospinal fluid flow cytometry at Bach Mai Hospital from January 2022 to December 2023. Results: Abnormal lymphoid markers of lymphoma were detected in 23/33 cerebrospinal fluid samples by flow cytometry and 10 samples by morphological examination. Of the 6 patients with suspected lymphoma, 3 were newly diagnosed by immunomarker analysis, which significantly increased the detection rate compared to morphological testing in cerebrospinal fluid samples alone. Conclusion: This study showed that morphological testing combined with flow cytometry significantly increased the detection rate compared to morphology alone in cerebrospinal fluid samples.
