ABSTRACT

Objective To explore the irradiation-increased krebs yon den lungen-6 (KL-6) in predicting radiation pneumonitis (RP) after lung cancer radiotherapy.Methods A total of 87 hospitalized patients with Ⅰ-Ⅲ stages of lung cancer from June 2015 to December 2015 were followed up,and their clinicopathological data and serum KL-6,transforming growth factor-beta 1 (TGF-β1)and lactate dehydrogenase (LDH)before and 3 months after radiotherapy were analyzed to determine their role in predicting RP induction in lung cancer.Results Among the 87 lung cancer patients based on clinical symptoms and chest CT,13 patients were diagnosed with ≥2 grape RP.Before radiotherapy,the average levels of serum KL-6 were (247 ± 105.44) U/ml in 13 patients with ≥ 2 grape RP and (209 ± 71.09) U/ml in 74 cases 0/1 grape RP,respectively.Within 3 months after radiotherapy,the highest level of KL-6 approached to (456 ± 202.84) and (222 ± 80.42) U/ml with increase ratios of 2.01 ± 1.04 and 1.13 ± 0.60 in the ≥2 grape RP and 0/1 grape RP,respectively.The difference of KL-6 levels between these two groups was significant (t =2.901,P < 0.005).While the levels of TGF-β1 and LDH did not change.ROC analysis showed that the sensitivity of the ratio of serum KL-6 increased after radiotherapy was 0.923% and the specificity was 0.851% at 1.435 as the critical value.Furthermore,the multi-variate logistic regression analysis showed that the ratio of KL-6 increased as an independent risk factor of ≥ 2 grade RP in lung cancer (OR =12.886,95% CI =3.372-49.247,P =0.002).Conclusions The increased ratio (≥ 1.435) of KL-6 is closely correlated with the ≥2 grape RP in lung cancer,which could be used as a predictor of ≥2 grape RP in lung cancer.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the value of serum neuron-specific enolase (NSE) before treatment in predicting brain metastases and prognosis of advanced non-small cell lung cancer (NSCLC).</p><p><b>METHODS</b>A total of 128 hospitalized patients with advanced NSCLC from Jan 2012 to Mar 2012 were followed up, and their clinicopathological data, serum NSE, carcinoembryonic antigen, cytokeratin 21-1 (cyfra21-1) levels, albumin (ALB), white blood cell (WBC) before treatment were analyzed retrospectively to determine the factors affecting brain metastasis and prognosis of advanced NSCLC.</p><p><b>RESULTS</b>Among the 128 NSCLC patients, 90 cases were of adenocarcinoma, 30 cases were of squamous cell carcinoma, and 8 cases were of large cell carcinoma. The median levels of pre-treatment NSE, CEA and cyfra21-1 were 13.6 ng/ml, 7.8 ng/ml and 6.1 ng/ml, respectively. The average levels of ALB and WBC were (35.41 ± 5.60) g/L and (8.16 ± 2.53) × 10⁹/ml, respectively. Multi-variate logistic regression analysis showed that serum NSE before treatment was associated with brain metastasis of advanced NSCLC (P = 0.030). Pre-treatment NSE levels were (34.18 ± 28.48) ng/ml in 28 patients with brain metastasis and (13.87 ± 4.49) ng/ml in 98 patients without brain metastasis (P < 0.05). The median survival time were 3.5 months in patients with normal levels of NSE, and 10.7 months in patients with elevated levels of NSE pre-treatment (P < 0.05).</p><p><b>CONCLUSIONS</b>A higher pre-treatment level of NSE is closely correlated with brain metastasis of advanced NSCLC, and can be used as a predictor of brain metastases in advanced NSCLC. High pre-treatment levels of NSE indicate a poor prognosis in advanced NSCLC patients.</p>
