Abstract:
Objective To explore the correlation of EGFR and Ki-67 expressions in lung adenocarcino-ma with MSCT features and general clinical characteristics. Methods According to the differences in EGFR 19/21 gene mutation in the tumor tissues ,120 patients with lung adenocarcinoma were divided into positive group or wild type group. And Ki-67 expression in the tumor tissues was also detected. The test results were analyzed ,and the clinical data and theMSCT imaging features were examined by using the SPSS 19.0. Results The expression of EGFR differed statistically with lymphatic metastasis ,organ metastasis ,pleural indentation ,andnodule types (P < 0.05),but had no statistical significance with age ,sex ,degree of differentiation ,tumor size ,tumor-lung boundary ,burr ,lobulated sign ,vacuole sign and pleural effusion.The high expression of Ki-67 had statistical sig-nificance with lymphatic metastasis and tumor size(P < 0.05)while had no statistical significance with other in-dicators.Ki-67 expression was significantly positively correlated with EGFR(P < 0.05). Conclusions Tumor size ,pleural indentation ,lymphatic metastasis ,organ metastasis and nodular types of lung adenocarcinoma have guiding significance in judging EGFR mutation , proliferation activity ,prognosis and therapy.
