RESUMO

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.

RESUMO

Objective@#To compare the difference of displacement between the vacuum bag fixation and the Orfit rack with thermoplastic membrane fixation of the cervical cancer patients, and to explore the individual fixation of the patients.@*Methods@#We retrospectively analyzed the clinical data of 66 patients diagnosed as cervical cancer in Zhangzhou Municipal Hospital of Fujian Province from December 2014 to April 2016. Among them, 33 patients were fixed with vacuum bag, 33 patients were fixed with the Orfit rack with thermoplastic membrane. The cone-beam computed tomography (CBCT) images were acquired daily for the first three times of the radiotherapy, followed by once every other day for a total of 15 times. The CBCT scan images were matched with the CT scan images, and the matching results were recorded and analyzed.@*Results@#The absolute value of the displacement in the left and right directions of the vacuum bag group was (0.28±0.30) cm, significantly lower than (0.38±0.46) cm in the Orfit rack with thermoplastic membrane group(P<0.001). The absolute value of the displacement in the anteroposterior direction of the vacuum bag group was (0.28±0.32) cm, with no significant difference of (0.27±0.23) cm in the Orfit rack with thermoplastic membrane group (P=0.580). The absolute value of the displacement in the up and down directions was (0.33±0.60) cm, with no statistically significant difference of (0.27±0.48) cm in the Orfit rack with thermoplastic membrane group (P=0.150). During the three times of CBCT scans, the differences of displacement in the left and right directions of the vacuum bag group were negligible, while apparently varied in the anteroposterior and up and down directions, however, the differences were not statistically significant (P>0.05). The change of the displacement in the three-dimensional direction in the Orfit rack with thermoplastic membrane group was marginal, and all of the differences were not significant(all P>0.05).@*Conclusions@#Both the vacuum bag fixation and the Orfit rack with thermoplastic membrane fixation are suitable for the cone-beam CT image-guided radiotherapy of cervical cancer patients. However, the displacement in the left and right directions of the vacuum bag fixation is smaller than the Orfit rack with thermoplastic membrane fixation. During the period of treatment, the mean value of the difference of displacement in the anterior and posterior directions of the Orfit rack with thermoplastic membrane fixation is mild, which can be used individually by the patients with a flexible body and good tolerance.
