Pre-operative CT scan is as an important imaging tool to prognosticate the disease and assess the operability. Along with an oesophagoduodenoendoscopy, majority of these tumors were detected pre-operatively.
The aim of this study is to see the association of pre-operative CT scan features and its malignant potential in our local setting and this study has shown that there is association of tumor morphology of extramural to the malignant potential of Gastrointestinal stromal tumors. Most GIST tend to arise from the extramural part of the bowel and this is consistent with our study however it was reported that colonic GISTs tend to arise frequently from the mural part of the bowel in contrast with our finding of a single patient with a rectal …show more content…
Although some studies showed a male predominance, our study and previous studies showed no gender preference. In previous studies, size had a significant association to the malignant potential of the tumor whereby the larger the tumor, the higher the risk of malignant potential however this was not the case for our study. This may be due to our smaller size whereby 19 patients were excluded and majority of which were excluded did not have a pre-operative CT scan, alternate diagnosis post-operatively on histopathology and some records could not be found for the …show more content…
This was a retrospective study of cases collected over 9 years which presented in University Malaya Medical Centre and Specialist Centre which is a tertiary care centre. Only patients which had pre-operative CT scans were included in this study therefore the number of patients in this study is smaller. Ideally patients diagnosed with GIST should have pre-operative CT scan to prognosticate and assess the resectability. A larger sample size of patients with GIST with pre-operative CT scans in future cases should be included to determine further associations with the histopathological
