Abstract:

Objective

To analyze the correlation and clinical significance of serum pentraxin 3 (PTX3) expression with bone metastasis of non-small cell lung cancer (NSCLC).

Methods

A total of 184 metastatic NSCLC patients treated in Tangdu Hospital from September 2022 to July 2023 were selected. 69 cases of NSCLC bone metastasis were the observation group, and 115 cases of NSCLC non-bone metastasis were the control group. The clinical information of patients was collected, and the expression level of serum PTX3 was detected by enzyme-linked immunosorbent assay (ELISA). Compared serum PTX3 content of two groups, we analyze the correlation of PTX3 expression with NSCLC bone metastases and compared serum PTX3 expression in NSCLC bone metastases before and after treatment. Receiver operating characteristic (ROC) curve was used to determine the diagnostic value of serum PTX3 for NSCLC bone metastasis.

Results

There were no significant differences in gender and age between the two groups (P>0.05). There were 69 cases of bone metastasis in the observation group and 40 cases of lymph node metastasis, 31 cases of lung metastasis, 21 cases of brain metastasis, 14 cases of liver metastasis and 12 cases of adrenal metastasis in the control group. The serum PTX3 in the observation group was 104.80 (175.48) ng/ml, which was higher than that in the control group 21.48 (22.02) ng/ml (P<0.05). There were no significant differences of serum PTX3 expression in NSCLC bone metastasis patients with different clinical characteristics, including gender, age, history of cancer, smoking index, BMI index, pathological type, primary tumor location, single organ metastasis, number of metastatic lesions, nature of bone metastasis, blood calcium and serum alkaline phosphatase (P>0.05). There was no significant difference in the expression of serum PTX3 in NSCLC patients with bone metastasis before and after clinical treatment(P>0.05). The area under ROC curve of serum PTX3 in the diagnosis of NSCLC with bone metastasis was 0.860(95%CI: 0.802~0.919), with the optimal diagnostic cut-off value, sensitivity and specificity of 35.385 ng/ml, 0.855 and 0.748, respectively.

Conclusions

The high expression of serum PTX3 is closely related to the bone metastasis of NSCLC, which has a good diagnostic value for NSCLC bone metastasis and clinical significance.s
