Abstract:

Objective

To analyze the expression characteristics of micro RNA (miRNA) in non-small cell lung cancer (NSCLC) and predict the resistance of platinum drugs.

Methods

All of 105 patients with NSCLC admitted to our hospital from September 2021 to April 2023 were selected as subjects, 66 patients with platinum therapy sensitivity were selected as control group, and 39 patients with drug resistance were selected as observation group. miRNA expression was detected by polymerase chain reaction (PCR). Multivariate Logistic regression was used to analyze the influencing factors of platinum drug resistance in NSCLC, and the expression characteristics of miRNA were analyzed by receiver operating characteristic curve (ROC) to predict platinum drug resistance in NSCLC.

Results

The expression levels of miRNA-125b (0.92±0.21), miRNA-106a (0.87±0.22), miRNA-181a (0.89±0.13) and miRNA-196a (1.01±0.31) in observation group were higher than those in control group (1.75±0.35). miRNA-106a (2.45±0.47), miRNA-181a (1.04±0.21),miRNA-196a (2.48±0.55), miRNA-148b (1.78±0.47) in observation group was lower than that in control group (0.97±0.16) (P<0.05). Multivariate Logistic regression analysis showed that the expression levels of miRNA-125b (OR=1.642), miRNA-106a (OR=2.052), miRNA-181a (OR=2.092), miRNA-196a (OR=1.508) and miRNA-148b (OR= 0.385) were platinum drug resistant in NSCLC influencing factors of the situation (P<0.05); ROC curve showed that the expression levels of miRNA-125b, miRNA-106a, miRNA-181a, miRNA-196a and miRNA-148b predicted the AUC of platinum drug resistance in NSCLC were 0.795,0.895, 0.733, 0.878 and 0.888,respectively. The predictive value of miRNA-106a was high. When the optimal diagnostic threshold was 1.220, the sensitivity and specificity of mirNA-106A for predicting platinum drug resistance in NSCLC were 76.62% and 96.97%.

Conclusion

The expression characteristics of miRNA can predict platinum drug resistance in NSCLC. NSCLC patients with high expression levels of mirNA-125b,mirNA-106A, mirNA-181A, mirNA-196a and low expression levels of mirNA-148b are prone to platinum drug resistance.
