Abstract:
Background: Lung cancer is the world's highest mortality and incidence rate of malignancy, and the prognosis survival rate is significantly lower than other tumors. A novel bio-physics based multi (pan)-cancer test technology named Cancer Differentiation Analysis Technology (CDA) has been developed and investigated for evaluating and monitoring lung cancer therapeutic responses. Methods: A total of 686 patients diagnosed with different sub-types of lung cancer were included in this study. CDA levels were concurrently measured in peripheral blood obtained from 686 patients during the treatment. According to the response evaluation criteria in solid tumors (RECIST) 1.1 standard, the efficacy of 686 patients after treatment was evaluated, and the diagnostic efficacy of CDA technology was evaluated by receiver operating characteristic (ROC) curve. Results: Clinical pathological parameters of the patients are listed in Table 1. The higher the CDA value, the worse the curative effect. CDA value of lung cancer in CR (complete response) group was significantly lower than that in other 3 groups (p & lt;0.05). CDA value of adenocarcinoma lung cancer in CR group were significantly lower than that in SD (stable disease) group (p & lt;0.05). For non - metastatic lung cancer, CDA value in CR group was significantly lower than that in SD group (p & lt;0.05) The receiver ROC analysis showed that the area under curve (AUC) of lung cancer group, NSCLC group, adenocarcinoma lung cancer group, were 0.756, 0.772, and 0.792, respectively. The AUC of early lung cancer group, and non - metastatic lung cancer group were 0.794, and 0.851. Conclusions: CDA appears to have the ability to predict and monitor therapeutic responses to lung cancer surgery and chemotherapy treatments. In most cases, the CDA of CR patients is low, and there is a good correlation between CDA and curative effect in early lung cancer. CDA could be a potential candidate for evaluating lung cancer, especially for early stage lung cancer therapeutic response.
