Fine needle aspiration cytology in the evaluation of lymphoid lesions: a retrospective study of the utility of flow cytometry in conjunction with morphology.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND AND
objectiveFine needle aspiration (FNA) cytology, in conjunction with flow cytometry, is now widely used as a reliable and accurate method for the assessment of various lymphoid lesions, especially for lesions situated in odd locations where obtaining biopsy and monitoring for recurrence in previously diagnosed cases of lymphoma are difficult. The objective of this study was to determine the utility of FNA and immunophenotyping in the assessment of lymphoid lesions, and to find whether flow cytometry is more useful in the evaluation and subclassification of the small cell morphology group of lymphomas than in the large cell morphology group of lymphomas. DESIGN AND
settingRetrospective analysis of patients diagnosed with lymphoma over at a 5-year period. PATIENTS AND
methodsAll 175 FNA cases were followed carefully either clinically or histologically for at least 5 years. We compared the utility of flow cytometry in the diagnosis of small cell morphology lymphomas to large cell morphology lymphomas.
resultsFlow cytometry was performed on 72 of 175 (41%) of FNA specimens clinically suspicious of lymphoma. The excisional follow-up biopsy was obtained in 78 of 175 (44.5%) cases. Based on cytomorphologic evaluation, 82 cases (47%) were considered negative, 34 cases (19%) were considered atypical, 32 cases (18%) were positive for NHL-small cell morphology, 21 cases (12%) were positive for non-Hodgkin lymphoma (NHL)-large cell morphology, 3 cases (2%) were positive for NHL, and 3 cases (2%) were nondiagnostic. Immunophenotyping utilizing flow cytometry was the diagnostic parameter in 28 of 32 cases (88%) of the NHL-small cell morphology group and in 11 of 24 cases (46%) of the NHL-large cell morphology/Hodgkin lymphoma group.
conclusionsImmunophenotyping by flow cytometry is more essential for the accurate evaluation and classification of small cell morphology than large cell morphology lymphoid lesions in FNA cytology.
