本文报道了30例食管癌患者及30例正常人外周血淋巴细胞的微核检查。食管癌患者外周血微核淋巴细胞出现率为86.67%,外周血淋巴细胞微核出现率为2.6‰,微核淋巴细胞的多微核淋巴细胞出现率为23%;结果表明三者的出现率均高于对照组(P<0.01)。因此,外周血淋巴细胞微核的检查是否可作为食管癌的临床辅助诊断指标,值得研究。 This paper reports the micronucleus test of peripheral blood lymphocytes in 30 patients with esophageal cancer and 30 normal persons. The frequency of micronuclei lymphocytes in peripheral blood of esophageal cancer patients was 86.67%, the frequency of micronuclei in peripheral blood lymphocytes was 2.6 ‰, and the frequency of polynuclear lymphocytes in micronuclei lymphocytes was 23%; the results showed that the frequency of three micronuclei were observed. All were higher than the control group (P<0.01). Therefore, whether the micronucleus test of peripheral blood lymphocytes can be used as an auxiliary diagnostic indicator for esophageal cancer is worth studying.
