对肺癌患者血清脂结合唾液酸的动态检测结果发现，肺癌患者经化疗或放疗后血清ＬＳＡ含量下降，在临床缓解期保持在低水平。当ＬＳＡ再次升高时，预示肿瘤复发或转移。化疗或放疗前检测血清ＬＳＡ可作为诊断、鉴别诊断和分期的指标，而治疗开始后的ＬＳＡ动态检测对判断疗效、监测肿瘤的复发或转移很有价值。急性炎症是造成良性疾病组假阳性的主要原因，炎症控制后检测ＬＳＡ可明显降低假阳性率。
The results of dynamic detection of serum lipid-associated sialic acid in lung cancer patients showed that serum LSA levels decreased after chemotherapy or radiotherapy in patients with lung cancer, and remained low during clinical remission. When LSA rises again, it predicts tumor recurrence or metastasis. The detection of serum LSA before chemotherapy or radiotherapy can be used as an indicator for diagnosis, differential diagnosis, and staging, and the dynamic detection of LSA after the start of treatment is valuable for judging efficacy and monitoring tumor recurrence or metastasis. Acute inflammation is the main cause of false positives in the benign disease group. Detection of LSA after inflammation control can significantly reduce the false positive rate.
