Objective:To study the effect of cisplatin-based concurrent radiochemotherapy on the malignant degree of advanced cervical cancer and the expression of proto-oncogene and tumor suppressor genes.Methods: A total of 82 patients with advanced cervical cancer who were treated in our hospital between July 2013 and December 2016 were collected and divided into control group and observation group according to random number table, with 41 cases in each group. The control group of patients received radiotherapy alone, while the observation group of patients received cisplatin-based concurrent radiochemotherapy. Tumor marker levels in serum as well as proto-oncogene and tumor suppressor gene expression in tumor tissue were compared between two groups of patients before and after treatment.Results:Before treatment, differences in tumor marker levels in serum as well as proto-oncogene and tumor suppressor gene expression in tumor tissue were not statistically significant between two groups of patients. After treatment, serum tumor markers SCC, CA50, CA724 and CEA levels of observation group were significantly lower than those of control group;proto-oncogene DEK, c-myc and PIK3CA mRNA expression in tumor tissue were significantly lower than those of control group;tumor suppressor genes p53, SOCS-1, FHIT and PTEN mRNA expression in tumor tissue were significantly higher than those of control group.Conclusions:Cisplatin-based concurrent radiochemotherapy can effectively reduce the tumor malignancy and balance the proto-oncogene / tumor suppressor gene expression in patients with advanced cervical cancer.
