Median age of patients was 68 (range 43\u201391) years. 24 patients (57.1%) were female. Tumour size ranged from 1.0\u2005 to 12.7\u2005cm with mean size of 5.46\u2005cm. Metastasis was present in 19 (45.2%) patients at diagnosis with distant metastases in 12 patients. Liver was the most common site of metastases. Histology and immunohistochemical analysis was available in 32 (76.2%) patients. Most common histology was spindle cell morphology 17\/32 (53.1%) followed by epithelioid 9\/32 (28.1%) and mixed morphology 5\/32 (15.6%). The positive rate for KIT protein (CD117) was 90.6%, while that for CD34 was 75.0%. 12\/25 (48.0%) and 8\/23 (34.8%) patients were categorised as high risk as per NIH and AFIP risk scores, respectively. 23\/42 (54.8%) patients underwent surgical resection, after which 5\/23 (21.7%) had adjuvant imatinib therapy. Imatinib was given as primary therapy in 14\/42 (33.3%) patients.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Surgery alone may not be a curative treatment for GISTs.
