A Retrospective Study of Chemotherapy and 3D-Image-Guided Afterloading Intracavitary Radiotherapy in Locally Advanced Cervical Cancer

Abstract

Aim. To investigate the value of neoadjuvant chemotherapy combined with 3D-image-guided afterloading intracavitary radiotherapy in locally advanced cervical cancer (LACC). Methods. Patients with cervical cancer admitted to our hospital from January 1, 2020 to January 1, 2021 were retrieved and analyzed. Cases treated with neoadjuvant chemotherapy and 3D-image-guided afterloading intracavitary radiotherapy were assigned into the observation group (OG), while cases with neoadjuvant chemotherapy alone were assigned into the control group (CG). The short-term effects were determined by RECIST 1.1. Total effective rate TR = complete remission CR + partial remission PR . The serum levels of squamous epithelial cell carcinoma antigen (SCC-Ag), glycoantigen 125 (CA125), carcinoembryonic antigen (CEA), and vascular endothelial growth factor (VEGF) were assessed. In view of the difference between tumor markers and diameters before and after treatment, the correlation between them was analyzed by Pearson test. The adverse events were compared, and the amount of operative bleeding and operation time were evaluated. Cox regression analysis was conducted to assess the influencing factors of 1-year disease-free survival time. Results. Sixty-seven patients were retrieved, including 30 cases in the OG and 37 cases in the CG. There were no significant differences in age, pathological type, tumor size, FIGO stage, past medical history, or smoking history between the two groups ( P > 0.05 ). The TR of patients in the OG was higher than that in the CG ( P < 0.05 ). The SCC-Ag, CA125, CEA, and VEGF levels in the OG decreased markedly after treatment ( P < 0.001 ). The difference in SCC-Ag, CA125, CEA, and VEGF was positively correlated with the difference in tumor diameter before and after treatment ( P < 0.05 ). The incidence of adverse events revealed no obvious difference between the OG and CG ( P > 0.05 ). Cox regression analysis showed that FIGO stage and treatment regimens were independent prognostic factors for 1-year disease-free survival ( P < 0.05 ). Conclusion. Neoadjuvant chemotherapy combined with 3D-image-guided afterloading intracavitary radiotherapy can improve the TR rate and 1-year disease-free survival of LACC patients without increasing the incidence of adverse events.

Meta-analysis of the efficacy and safety of Xihuang Pills/capsules in adjuvant treatment of uterine cervical neoplasms

“…The utilization of radiotherapy and chemotherapy in treating patients with cervical neoplasms significantly enhances survival rates. [ 37 ] However, cancer treatment entails cytotoxicity, whether by chemotherapy or radiotherapy, leading to the destruction of tumor cells and adversely affecting normal bodily functions, resulting in various severity levels of side effects that significantly impact treatment compliance and overall quality of life. [ 38 ] According to TCM theory, radiotherapy and chemotherapy may cause excessive heat toxicity, depletion of jin fluid, disharmony between yin and yang, disturbances in qi and blood circulation, and dysfunction of viscera and meridians.…”
