Role Of Scrape Cytology In The Intraoperative Diagnosis Of Tumour

ABSTRACT

Background: Intra operative pathological assessment has offered a very valuable service in patient management. The present study was done to evaluate the status of intraoperative cytology as a diagnostic and supportive investigation for various tumours. To evaluate the utility of imprint /scrape cytology for the rapid diagnosis ofAim and objectives: surgically removed specimens. 70 surgically removed specimens from various organs andMaterials and Methods: systems were studied. Smears were taken from each specimen before formalin fixation and stained by modified rapid H&E and Papanicolaou staining. Cytological diagnosis was made and then results were compared with the histological diagnosis taking the latter as the gold standard. Out of the 70 cases sampled, 70 were satisfactory forResults: evaluation. Overall accuracy rate was 87.14 % .Six cases of false positive diagnosis and 3 false negative diagnosis were made .Positive predictive value was 75% and negative predictive value was 93.47%. Imprint /scrapeConclusions: cytology is a good complement for the rapid diagnosis in histopathological study of tumor/tumor like lesions and intra operative cytology can be used an adjunct to frozen section.
