Abstract
Large unstained cells (LUC) is a differential count parameter reported by routine hematology analysis, and LUC percentages (LUC %) reflect active lymphocytes and peroxidase-negative cells. We aimed the evaluate the LUC % parameter in routine practice towards malignant neoplasms, stated or presumed to be primary, of lymphoid, haematopoietic, and related tissue. LUC analysis was performed with Siemens ADVIA® 2120 Hematology System. Data were obtained from Ankara Bilkent City Hospital’s laboratory information system. A statistical difference in the LUC % data in the case of LUC % <4.5 and LUC % ≥4.5 among preliminary diagnoses was observed (p<0.001). According to the Kruskal-Wallis test, a statistical difference was observed between preliminary diagnosis and LUC % values (p<0.001). The One-way ANOVA test with Bonferroni correction was performed for post hoc multiple comparisons of the preliminary diagnosis among LUC%. LUC % was higher in Hodgkin Lymphoma patients than Myeloid leukaemia patients (p=0.002). LUC % was higher in the Lymphoid leukaemia patients than in the patients with Hodgkin lymphoma (p<0.001), Other and unspecified types of non-Hodgkin lymphoma (p<0.001), Multiple myeloma and malignant plasma cell neoplasms (p<0.001). LUC % was higher in patients with leukemia unspecified cell type than Hodgkin lymphoma (p<0.001), Follicular lymphoma (p<0.001), Non-follicular lymphoma (p<0.001), Mature T/NK-cell lymphomas (p<0.001), Other and unspecified types of non-Hodgkin lymphoma (p<0.001), Malignant immunoproliferative diseases (p<0.001), Multiple myeloma and malignant plasma cell neoplasms (p<0.001), Lymphoid leukaemia (p<0.001), Myeloid leukaemia (p<0.001), Other leukaemias of specified cell type patients (p<0.001). Prospective studies may be useful in assessing LUC%.
