Efficacy and safety of intensity Modulated Radiation therapy combined with Concurrent Chemoradiotherapy in the treatment of Recurrent Cervical Cancer.

Objective: To evaluate the clinical value of intensity modulated radiation therapy (IMRT) combined with concurrent chemoradiotherapy in the treatment of recurrent cervical cancer. Methods: This was a retrospective study. Eighty patients with recurrent cervical cancer were recruited and randomly divided into two groups: the experimental group and the control group, with 40 cases in each group at The Fourth Hospital of Hebei Medical University from April, 2017 to April, 2022. Patients in the control group were only given IMRT, while those in the experimental group were given concurrent chemoradiotherapy with paclitaxel and cisplatin based on IMRT. All patients were evaluated for clinical efficacy, adverse drug reactions, and differences in the levels of SCC-Ag, CEA and CA724 and other tumor markers before and after treatment. Results: The total effective rate in the experimental group was significantly better than in the control group (p=0.02). The incidence of adverse reactions was 40% in the experimental group and 32.5% in the control group, with no statistically significant difference (p=0.48). After treatment, the levels of tumor markers in the experimental group were significantly lower than those in the control group, with a statistically significant difference (p=0.00). The three years survival rate was 80% in the experimental group and 55% in the control group (p=0.03). The five years survival rate was 65% in the experimental group and 42.5% in the control group, with a statistically significant difference (p=0.04). Conclusion: Intensity modulated radiation therapy (IMRT) combined with concurrent chemoradiotherapy is a safe and effective regimen for recurrent cervical cancer, boasting significant clinical efficacy, reduced tumor markers, no significant increase in adverse reactions, and significantly improved three-years and five years survival rate.
