Expression levels of SCCA and CYFRA 21-1 in serum of patients with laryngeal squamous cell carcinoma and their correlation with tumorigenesis and progression

Purpose To explore the concentration of squamous cell carcinoma antigen (SCCA), cytokeratin fragment antigen 21-1 (CYFRA21-1) in patients with laryngeal squamous cell carcinoma (LSCC) and its correlation with tumorigenesis and progression. Methods A total of 78 patients with LSCC admitted to our hospital from February 2010 to January 2016 were enrolled as the research group (RG), and another 41 healthy volunteers from the same period were selected as the control group (CG). The serum concentrations of SCCA and CYFRA21-1 in patients with LSCC were detected by ELISA, whose diagnostic value in LSCC were further analyzed by ROC curve. The prognosis and survival curves of patients with LSCC were observed according to the median value of serum SCCA and CYFRA21-1 concentrations. Results The concentration of CYFRA21-1 and SCCA in the RG was significantly higher than that in the CG (p < 0.050). The SCCA and CYFRA21-1 identified a significant difference in smoking, lymphatic metastasis, TNM staging, and differentiation degree (p < 0.050). The survival rate of the SCCA low-concentration group was significantly better than that of the high-concentration group,p < 0.050. The survival rate of the CYFRA21-1 low-concentration group was markedly better than that of the high-concentration group,p < 0.050. Conclusions SCCA and CYFRA21-1 are highly concentrated in LSCC patients, which have good diagnostic efficacy for LSCC. In addition, they play some certain role in the occurrence and development of LSCC, and are expected to be markers for early diagnosis and prognosis of this disease.

Automated summary

The study indicates that SCCA and CYFRA21-1 are highly concentrated in patients with LSCC, showing good diagnostic efficacy for the disease. The survival rate of patients with low concentrations of SCCA and CYFRA21-1 is significantly better than those with high concentrations.
