Soluble major histocompatibility complex class I-related chain A in sera of patients with oral squamous cell carcinoma / 中南大学学报(医学版)

ABSTRACT

OBJECTIVE@#To examine the expression of soluble major histocompatibility complex class I-related chain A (sMICA) in the serum in patients with oral squamous cell carcinoma (OSCC) and to explore its clinicopathological significance.@*METHODS@#Seventy-eight OSCC patients were selected as an experiment group, and 19 healthy persons as a control group. The sMICA in the serum in the experiment group and the control group was detected by enzyme-linked immunosorbent assay.@*RESULTS@#The detection rate of sMICA in the serum in the experiment group was 98.7% (77/78), with the 95% confidence interval 74.30-93.95 pg/mL and the median 82.17 pg/mL, The detection rate in the control group was 94.7% (18/19), with the 95% confidence interval 29.48-50.30 pg/mL and the median 37.54 pg/mL. The sMICA in the serum in the experiment group was higher than that in the control group (P0.05).@*CONCLUSION@#The sMICA in the serum in the OSCC patients increases, and is related with the tumor size, disease stage and regional lymph node status. Determination of sMICA in the serum may provide useful information to evaluate the immune state of OSCC patients.
