Value of Fine-Needle Aspiration Cytology in Diagnosis of Hodgkin’s Lymphoma and Anaplastic Large Cell Lymphoma: One Centre Experience

The aim of the study was to determine the value and limitations of cytology in diagnosis of Hodgkin’s lymphoma (HL) and anaplastic large cell lymphoma (ALCL) as well as differentiation between these two entities. We analysed the FNA cytodiagnoses and histopathological reports, as well as treatment and survival in 89 newly diagnosed consecutive patients with these lymphomas treated in our clinical department. These patients (40 male, 49 female ; age range 16– 93 years ; 44 in clinical stages I–II ; 38 with B symptoms) were diagnosed and treated during a period of 64 months (1.1.2004–1.5.2009). The FNA cytodiagnoses were available in 86 patients and the pathohistological diagnoses were available in 84 patients. Cytology revealed 65 classic HL, 18 ALCL and three patients in which diagnosis was not informative.Among 65 FNA cytodiagnoses of HL, comparison with histopathology was made in 61 cases and the histopathological diagnoses were as follows: 56 (91.8%) HL ; three ALCL ; one diffuse large B cell lymphoma and one marginal zone B cell lymphoma. In the group of 18 FNA cytodiagnoses of ALCL eight patients (53.3%) had definitive diagnosis of ALCL (either as T-cell or O type), five (33.3%) of HL and in three cases a histopathological diagnosis could not be made. These results confirm the value of FNA in diagnostic procedure in patients with HL and ALCL, especially in HL group of patients. Since we have an almost uniform group of patients according to therapeutic approach, we did univariate analyses and found out that patients with FNA cytodiagnoses of HL, younger than 55 years, with early stage of the disease and without B symptoms had significantly longer overall survival (OS). FNA cytodiagnosis has clinical relevance in differentiation between HL and ALCL.
