U skladu sa podacima iz nekoliko radova o ovom problemu, upoređivali smo histološke nalaze sa citomorfološkim u aspiratima iglom. Takođe smo analizirali uzajamni odnos takvih nalaza sa ukupnim preživljavanjem (UP). Metode. Analizirane su aspiracjske biopsije tankom iglom iz perifernih limfnih žlezda i Internacionalni indeks prognoze (IIP) kod 81 bolesnika sa nehodžkinovim limfomom (NHL). Upoređivani su ovi nalazi sa ukupnim preživljavanjem. Rezultati. Shodno kriterijumima Radne klasifikacije dominantna ćelijska populacija bila je: kod 18 bolesnika mali limfociti, 21 bolesnik je imao male zarezane ćelije, kod 18 bolesnika mešovita populacija (male zarezane i velike ćelije), kod 21 velike ćelije (imunoblasti), 2 bolesnika Burkitt tip i kod jednog limfoblasti. Na početku su 32 bolesnika imala nizak IIP, 32 bolesnika srednji i 17 bolesnika srednje visok. Potvrdili smo da citomorfologija (p = 0,013) i IIP (p = 0,016) statistički značajno utiču na ukupno preživljavanje. Tokom praćenja od 48 meseci, UP je bilo 37,2 meseca za bolesnike sa dominatno malim limfocitima, 32 meseca za bolesnike sa malim zarezanim ćelijama (PH ekvivalent sa indolentnim-NHL). Za bolesnike sa dominantno mešovitom ćelijskom populacijom, velikim ćelijama i Burkitt ćelijama UP je bilo 17, 14,4 i 9,3 meseca, respektivno (PH ekvivalent sa agresivnim NHL). Bolesnici sa niskim IIP imali su najviše UP, 36 meseci sa srednjim i samo 11,6 meseci sa srednje visokim IIP. Zaključak. Zaključili smo da incijalni citološki i klinički profil bolesnika sa NHL može dati brzu i relevantnu informaciju za planiranje adekvatne terapije.

Fine-needle aspiration biopsy is a quick, economical, and safe initial method in managing a patient with suspected lymphoma. According to a few reports on this preoblem, the aim of this study was to compare histological findings to cytomorphological ones in needle aspirates. We also compared these findings to the overal survival (OS) time. Methods. We analyzed the fine-needle aspiration biopsies of peripheral lymph nodes, and the International Prognostic Index (IPI) in 81 patients with non-Hodgkin's lymphoma (NHL). We put these findings into correlation with OS time. Results . According to the International Working Formulation (IWF) criteria, the dominant cell population was as follows: 18 patients had the small cell population, 21 patients had small cleaved cells, 18 patients had the mixed cell population, 21 patients had large cell population, 2 patients had Burkitt lymphoma type, and 1 patient had the dominant lymphoblasts. On presentation, 32 patients had a low IPI index, 32 patients had a low intermediate, and 17 patients had a high intermediate IPI. We confirmed the statistical significance (Kaplan-Mayer) of cytomorphology (p = 0.013) and IPI index (p = 0.016) for survival time. During a 48-month follow-up, OS was 37.2 months for the patients with the dominant small cells, and 32 months for the patients with small cleaved cells (PH equivalent to indolent NHL). For the patients with the dominant mixed cell population, large cell population and Burkitt limphoma cell, OS were 17, 14.4, and 9.3 months, respectively (PH equivalent to aggressive NHL). Patients with low IPI had the highest OS, 36 months for the low intermediate and only 11.6 months for the high intermediate IPI index. Conclusion. We concluded that an initial cytological and clinical profile of patients with NHL, might give a quick and relevant information for planning an adequate therapy.
