ITDs in c-kit exon 11 were found in tumours that generally had a higher Patnaik (p = 0.002) and Kiupel (p < 0.001) grading, a higher mitotic count (p < 0.001), an increased number of Ki67-positive cells (p = 0.006), and an aberrant KIT pattern (p = 0.018). This evidence concerns the gene MKI67 and neoplasm.
