A STUDY OF PLEURAL EFFUSION BY COMBINED APPROACH OF CONVENTIONAL SMEAR AND CELL BLOCK TECHNIQUE

Abstract

BACKGROUND: Cytological examination of pleural uid is of paramount importance not only for diagnosis, staging, prognostication and management of malignancy also gives information about various inammatory and non-inammatory conditions. Conventional smear method has some disadvantages which can be overcome by cell block technique. To compare cytomorphological features ofAIMS AND OBJECTIVES: conventional smears versus cell block technique and also to evaluate the diagnostic efcacy of a combined approach of conventional smear study and cell block technique. 150 Sterile uid sample were processed in cytology section, Department of Pathology,MATERIAL AND METHOD: DECCAN COLLEGE OF MEDICAL SCIENCES, HYDERABAD. This study was conducted over a period of one and half years from January 2018 to June 2019. Each sample was divided into two equal parts one part was subjected to conventional smear method and other part was subjected to cell block technique. Statistical analysis was done using Microsoft Excel to calculate sensitivity and specicity of conventional cytosmears and cell block technique.RESULT: Sensitivity and additional yield for malignancy was 50% more by cell block method.
