dc.description.abstractGastrointestinal stromal tumours (GISTs) are the most common non epithelial, mesenchymal tumours of the gastrointestinal tract and amount to 1 to 3% of all gastrointestinal tumours. Histologically, GISTs demonstrate considerable morphologic variation.The aim of the study was to evaluate the histo-morphological features of GIST and the expression of DOG1 and KI-67 in these tumours. Eleven cases of GISTs received during a five-year period at a tertiary care centre were analysed for their demographic parameters, morphology and risk stratification. Immunohistochemistry for DOG1 and Ki67 was performed for all the eleven cases.Inthis study there was a female preponderance with the mid -fifties being the median age of presentation. The stomach and small intestine were the common sites of involvement. The histologic type was predominantly spindle cell with a few cases of mixed tumours. DOG 1 was positive in all the tumours and Ki-67 index was markedly elevated in the epithelioid cell type and in the high-risk category of tumours.DOG 1 holds good as an important marker for clinically suspected GIST diagnosis and Ki-67 expression correlates with the risk stratification of the tumour and can be a good prognostic factoren_US
