Abstract:
Objective To determine the clinical value of cytological diagnosis of the impressed specimens in the radical gastrectomy for patients with gastric cancer. Methods During radical gastrectomies for 52 patients with gastric cancer, 232 impressed specimens were taken from the tumor tissues,paratumor tissues, proximal and distal incision margin,and partial lymph nodes respectively, to detect if there was tumor cells by cytological examination and compared with the pathology. Results In the tumor tissues,there were no pseudo positive specimen,and the pseudo negative specimen occurred in 1.In the incision margin,there was no pseudo negative specimen,while 12 pseudo positive specimens were found.In the paratumor tissues,there were 3 pseudo negative and 10 pseudo positive specimens.In all specimens,the sensibility was 92.8%; specificity was 85.8%; accuracy rate was 87.9%. Conclusions Cytological examination of the impressed specimens in radical gastrectomy is helpful in detecting residue tumor tissue in the incision margin, especially in hospitals without rapid pathologic examination.If cytological examination is combined with rapid pathological examination,the results will be better.
