摘　　要：Flow cytometric (FCM) and microspectrophotometric (MSP) measurements of cell nuclear DNA content were made in 53 fresh gastric carcinoma specimens and in 30 gastric mucosal specimens with chronic gastritis. DNA aneuploidy was found in 32/53 (60%) of gastric carcinomas, and appeared more frequently in wellor moderately differentiated tubular adenocarcinomas (90%) than in undifferentiated and mucousa cell carcinomas (23.6%) (P【0.001). No aneuploidy was found in chronic gastritis samples, but their proliferative cell fractions were higher than in normal control gastric mucosa samples (P【0.01). A comparison was made between FCM and MSP analyses of DNA content in 29 cases of gastric carcinoma, a high correlation rate (r=0.90) was found. The advantages and limitations of both methods are discussed, they may be used in combination for more precise cytochemical analysis.Flow cytometric (FCM) and microspectrophotometric (MSP) measurements of cell nuclear DNA content were made in 53 fresh gastric carcinoma specimens and in 30 gastric mucosal specimens with chronic gastritis.
