Scrape cytology – Diagnostic tool in large intestinal tumors

Abstract

: Gastrointestinal tumors, mainly esophagogastric and colorectal carcinomas constitute one of the major causes of morbidity and mortality worldwide. The early detection and treatment of gastrointestinal tumors has been shown to improve patient's survival significantly. The current study is carried out to know the efficiency of scrape cytology in diagnosis of large intestinal tumors by comparing with histopathological diagnosisThirty surgically removed large intestinal tumor specimens were studied. Scrapings were taken from representative areas of each specimen, spread on slides, stained with H/E and reported. The specimens were fixed in 10% formalin, grossed and routine histopathological processing was carried out, followed by staining with H/E, examined and reported. The diagnosis obtained by scrape cytology and histopathology was correlated and analyzedTotal 30 specimens were received and majority of them were of rectal tumors(20%) and sigmund colon tumors(20%), followed by rectosigmoid region tumors (17%). Over all the scrape cytology diagnosis showed concordance for 28 cases with histopathology diagnosis having diagnostic accuracy of 93.3%.:Scrape cytology is simple, rapid and economically feasible technique and can be useful as an adjunct for frozen section in intraoperative consultation.
