A study in gastric cancer suggests DECT parameters correlate with Ki-67 expression, a marker of cell proliferation.[24] There are also few studies on DECT in ovarian cancer, and most of the available studies are on the classification of benign and malignant ovarian tumors[29,30,34] or on monitoring the effect of systemic treatments on abdominal tumors,[36] but there are no studies on cytoreductive surgery. This evidence concerns the gene MKI67 and gastric cancer.
