Abstract:
Objective To investigate the expression of circular RNA ubiquitin-associated protein 2(circ-UBAP2)and RAS-related C3 botulinum toxin substrate 1(Rac1)in cervical cancer tissues and their relation-ship with radiotherapy efficacy and prognosis.Methods A total of 96 patients with cervical cancer admitted to the hospital from January 2019 to May 2021 were selected as the research subjects.Detect the expression of circ-UBAP2 and Rac1 in the cancer tissues and adjacent tissues of the patients.The clinical data of the patients were recorded.According to the radiotherapy efficacy,they were divided into patients with effective radiother-apy(n=62)and patients with ineffective radiotherapy(n=34),and the relationship between the expressions of circ-UBAP2 and Rac1 and the radiotherapy efficacy was analyzed.The survival conditions of the patients were followed up for 3 years and they were divided into the survival group(n=81)and the death group(n=15),and the clinical data of the two groups were compared.The relationship between the expressions of circ-UBAP2 and Rac1 and the survival prognosis of patients was analyzed by Kaplan-Meier.The risk factors influ-encing the prognosis of patients were analyzed by Cox regression.Results The circ-UBAP2 expression and the positive rates of Rac1 expression in cancer tissues were both higher than those in adjacent tissues,and the difference was statistically significant(P＜0.05).The effective rate of radiotherapy in patients with high ex-pression of circ-UBAP2 and Rac1 in cancer tissues was lower than that in patients with low expression of circ-UBAP2 and Rac1,and the difference was statistically significant(P＜0.05).The 3-year overall survival rate and average survival duration of patients with high expression of circ-UBAP2 and Rac1 in cancer tissues were lower than those of patients with low expression of circ-UBAP2 and Rac1,and the difference was statistically significant(P＜0.05).There were statistically significant differences in clinical stage,tumor differentiation degree,expressions of circ-UBAP2 and Rac1,and the proportion of lymph node metastasis between the two groups(P＜0.05).The results of Cox regression analysis showed that clinical stage Ⅱ B-Ⅲ,poorly differen-tiated tumor degree,high expression of circ-UBAP2 and Rac1,and lymph node metastasis were risk factors af-fecting the prognosis of patients(P＜0.05).Conclusion circ-UBAP2 and Rac1 are abnormally highly ex-pressed in cervical cancer tissues and are related to the radiotherapy efficacy and prognosis.
