ABSTRACT

Objective:To investigate the safety and efficacy of nimotuzumab combined with IMRT radiotherapy in the treatment of elderly patients with locally advanced cervical cancer (LACC).Methods:A retrospective analysis was conducted for 34 elderly LACC patients treated with nimotuzumab combined with IMRT radiotherapy or concurrent chemoradiotherapy in the Zhangzhou Affiliated Hospital of Fujian Medical University from June 2020 to December 2021. The efficacy and side effects were evaluated one and two years after treatment.Results:Median follow-up time was 13.3 months (6.1-24.3 months). A total of 24 cases of complete response (CR) and eight cases of partial response (PR) were achieved after treatment, with an objective response rate (ORR) of 94.1% (32/34). The tumor diameters were (49.56 ± 19.22) mm before treatment and (19.61 ± 14.59) mm after treatment, with a tumor regression rate (TRR) of 59.22%.The 1- and 2- year progression-free survival (PFS) rates were 84.9% and 84.9%, overall survival (OS) rates 91.8% and 87.2%, respectively, disease-free survival (DFS) rates 91.8% and 87.2%, respectively, and the cancer-specific survival (CSS) rates 95.7% and 90.9%, respectively. The main adverse events included radiation enteritis, leukopenia, hypoproteinemia and anemia.Conclusions:Nimotuzumab combined with IMRT radiotherapy or concurrent chemoradiotherapy is safe and effective in the treatment of LACC.
