ABSTRACT
Nuclear DNA content was analysed by means of flow cytometric measurements in 103 patients with gastric carcinomas, using paraffin-embedded archival tissue. DNA aneuploidy was found in 40 cases (38.8%). The mean DNA index of aneuploid tumors was 1.45(range 1.13 to 2.37). No significant association between ploidy and either age, sex, tumor location, size, stage, growth pattern, or histologic type was found. However, the incidence of aneuploidy was higher in high grade carcinomas than in low grade carcinomas; the incidence of aneuploidy was 10%, 68.8%, and 45.8% for Grade II, III, and IV carcinomas, respectively, as compared with Grade I carcinomas which were all diploid. On statistical analysis, Abnormal cellular DNA content was significantly correlated with high histologic grade (P<0.005). Patients with aneuploid cancer (39.2%) had a poorer prognosis than those with diploid cancer (70.0%) based on (P<0.01). The 2-year survival rate for advanced gastric carcinoma. Therefore, DNA ploidy might be a useful prognostic factor in cases of advanced gastric cancer.
