ABSTRACT

Objective:To explore the expression and detection significance of peripheral blood interferon-gamma (IFN-γ) and hepcidin-25 (Hepc-25) in primary gastric cancer combined with thalassemia minor.Methods:One hundred and fifty primary gastric cancer combined with thalassemia minor patients admitted to of Jiangsu Province Official Hospital from January 2017 to December 2019 were selected as the research group, and 150 cases of primary gastric cancer without thalassemia minor admitted in the same period were selected as the control group. The levels of peripheral blood IFN-γ and Hepc-25 in the two groups were determined by enzyme-linked immunosorbent assay, and the receiver operating characteristic curve (ROC) was used to evaluate the diagnostic sensitivity and specificity of peripheral blood IFN-γ and Hepc-25 on primary gastric cancer combined with thalassemia minor. The level of hemoglobin (Hb) was measured by the cyanmethemoglobin method, and the Pearson correlation analysis was used to analyzed the relationship among the peripheral blood IFN-γ, Hepc-25 and Hb levels in the research group.Results:The levels of peripheral blood IFN-γ and Hb in the research group were lower than those in the control group: (115.18 ± 27.05) ng/L vs. (137.17 ± 35.66) ng/L, (88.44 ± 10.71) g/L vs. (120.60 ± 29.46) g/L; the level of Hepc-25 in the research group was higher than that in the control group: (49.32 ± 15.05) μg/L vs. (32.66 ± 12.22) μg/L, and the differences were statistically significant ( P<0.05). There were no significant differences in the levels of peripheral blood IFN-γ, Hepc-25 and Hb between the patients with α-thalassemia and β-thalassemia ( P>0.05). The area under the curve (AUC) of thalassemia predicted by of peripheral blood IFN-γ level was 0.709.When the cut-off value was≤138.89 ng/L, its diagnostic sensitivity and specificity were 81.33% and 70.67% respectively, and when the serum AUC of Hepc-25 was 0.811 and cut-off value was ≥ 40.13 μg/L, its diagnostic sensitivity and specificity were 75.33% and 74.00% respectively. Pearson correlation analysis showed that in the research group IFN-γ and Hb had positive correlation ( r = 0.245, P<0.05), Hepc-25 and IFN-γ had negative correlation ( r = - 0.378, P<0.05); Hepc-25 and Hb had negative correlation ( r = - 0.647, P<0.05). Conclusions:The low level of IFN-γ and the high level of Hepc-25 in peripheral blood of patients with primary gastric cancer combined with thalassemia minor are related to Hb and have certain diagnostic value for thalassemia.
