对鼻咽癌患者血清及组织的乳酸脱氢酶(LDH)同工酶进行测定,发现初诊和复发鼻咽癌病人与正常人的血清酶谱虽然相似,但组织酶谱在患癌病人与慢性鼻咽炎病人之间却存在着显著性差异,放疗前后的组织酶谱亦显著不同。提示有可能将鼻咽组织的LDH同工酶谱分析作为一种辅助性诊断或评价疗效的指标。 Lactate dehydrogenase (LDH) isoenzymes in serum and tissues of patients with nasopharyngeal carcinoma were measured and it was found that although the serum zymograms of patients with newly diagnosed and recurrent nasopharyngeal carcinoma were similar to those of normal people, the tissue zymograms were in chronic cancer patients and chronic There was a significant difference between patients with nasopharyngitis, and the tissue zymograms before and after radiotherapy were also significantly different. It is suggested that the LDH isoenzyme analysis of nasopharyngeal tissue may be used as an aid to diagnose or evaluate the efficacy.
