同时检测了86例肺癌、56例良性肺病患者和127例健康者血清脂质结合唾液酸(LSA)和癌胚抗原(CEA)浓度。LSA对肺癌的诊断准确率(82.4％)高于CEA(67.6％)。诊断和鉴别诊断效果优于CEA;CEA仅对腺癌有较高的检出率,而LSA对小细胞肺癌和鳞癌也有较高的检出率;LSA水平及阳性率与肺癌病期相关,对肺癌病情的判断及分期优于CEA;33例肺癌患者LSA水平变化与疗效相关,对
At the same time, serum lipid-associated sialic acid (LSA) and carcinoembryonic antigen (CEA) concentrations in 86 patients with lung cancer, 56 patients with benign lung disease, and 127 healthy subjects were measured. The diagnostic accuracy of LSA for lung cancer (82.4%) was higher than that of CEA (67.6%). The diagnostic and differential diagnosis effect is better than CEA; CEA only has a higher detection rate for adenocarcinoma, while LSA has a higher detection rate for small cell lung cancer and squamous cell carcinoma; LSA level and positive rate are related to lung cancer stage, The judgment and staging of lung cancer is better than CEA; the change of LSA level in 33 lung cancer patients is related to the curative effect.
