Supplementary Material for: Pretreatment Pokemon Level as a Predictor of Response to Cisplatin and Paclitaxel in Patients with Unresectable Non-Small Cell Lung Cancer Q.-L.Zhang X.-Z.Xing F.-Y.Li Y.-J.Xing J.Li 2015 <b><i>Background:</i></b> We firstly investigated the expression of Pokemon in patients with non-small cell lung cancer (NSCLC), then characterized the role of Pokemon in evaluating the response to combined cisplatin and paclitaxel chemotherapy and prognosis. <b><i>Patients and Methods:</i></b> In this study, 61 patients with previously untreated locally advanced or metastatic NSCLC were treated with a combination chemotherapy comprising cisplatin and paclitaxel. The correlation between serum expression of Pokemon and effectiveness of chemotherapy was assessed. <b><i>Results:</i></b> The expression level of Pokemon in NSCLC patients was higher than that in healthy controls (p = 0.000), and was correlated with tumor size and TNM stage (p < 0.05). Kaplan-Meier analysis and Cox proportional hazard model demonstrated a poor response and shorter survival time in patients with pretreatment Pokemon levels in excess of 135.09 ng/ml compared to those with Pokemon levels below 135.09 ng/ml (p = 0.013). Pokemon ≥ 135.09 ng/ml was an independent risk factor for survival time in NSCLC patients undergoing combination chemotherapy (p = 0.018). <b><i>Conclusion:</i></b> The serum level of Pokemon correlated with efficacy of cisplatin and paclitaxel combination chemotherapy and survival time, which indicated that Pokemon may be a potentially useful biomarker for predicting treatment effectiveness of first-line chemotherapy and prognosis in NSCLC.
