本文报道了52例肺癌和43例肺结核及结核性胸膜炎病人的血清脂质结合唾液酸(LSA)的检测结果。肺癌组LSA水平显著高于结核组(P<0.001),其诊断敏感性达78.8％,结核组诊断特异性达90.7％,诊断总符合率为84.2％,表明血清LSA对肺癌和肺结核的鉴别颇有价值。癌性胸水病人血清LSA水 This paper reports the results of serum lipid-associated sialic acid (LSA) detection in 52 patients with lung cancer and 43 patients with tuberculosis and tuberculous pleurisy. LSA levels in the lung cancer group were significantly higher than those in the tuberculosis group (P<0.001), the diagnostic sensitivity was 78.8%, the diagnostic specificity in the tuberculosis group was 90.7%, and the diagnostic overall compliance rate was 84.2%, indicating that the serum LSA was able to distinguish between lung cancer and tuberculosis. valuable.
