Methods:Patients who were diagnosed with ⅠB-ⅡB cervical cancer and underwent surgical treatment in Navy General Hospital of PLA between February 2015 and May 2017 were selected as the research subjects and randomly divided into the neoadjuvant chemotherapy group who underwent preoperative neoadjuvant chemotherapy and the control group who underwent routine preoperative preparation. After surgical resection, the mRNA expression of tumor suppressor genes, proliferation genes as well as migration and invasion genes in cervical cancer tissue were determined by fluorescence quantitative PCR. Results: After surgical resection, tumor suppressor genes THBS2, PTEN, LAST1 and eIF4E3 mRNA expression in cervical cancer tissue of adjuvant chemotherapy group were significantly higher than those of routine surgery group whereas proliferation genes RUNX2, CyclinD1, ALEX1, ALDH1 and ABCG2 as well as migration and invasion genes CXCL12, CXCR4, MMP9, S100A6 and N-cadherin mRNA expression were significantly lower than those of routine surgery group. Conclusion:Preoperative neoadjuvant chemotherapy can inhibit the proliferation, migration and invasion of cancer cells within the lesions of patients with ⅠB-ⅡB cervical cancer.展开更多
