| Abstract:: |
| Objective To evaluate the effectiveness and safety of concurrent chemoradiotherapy combined with nimotuzumab in the treatment of patients with inoperable esophageal squamous cell carcinoma (ESCC).Methods A retrospective analysis was conducted on the clinical data of 503 patients with inoperable ESCC who underwent concurrent chemoradiotherapy in the Department of Radiation Oncology, Changzhou No. 2 People's Hospital Affiliated to Nanjing Medical University and Department of Radiation Oncology, Affiliated Hospital of Jiangnan University from 2014 to 2020. Among these patients, 69 received concurrent chemoradiotherapy combined with nimotuzumab (the combined therapy group) and 434 received concurrent chemoradiotherapy alone (the concurrent chemoradiotherapy group). Patients of both groups were matched at a ratio of 1:2 using the propensity score matching (PSM) method. As a result, 168 patients were determined for clinical analysis, including 61 in the combined therapy group and 107 in the concurrent chemoradiotherapy group. The short-term efficacy and adverse reactions of both groups were compared. The overall survival (OS) curves and progression-free survival (PFS) curves were plotted using the Kaplan-Meier method for the Log-rank test.Results The two groups showed no statistical difference (P > 0.05) in clinical baseline characteristics after the PSM. The objective response rate (ORR) of the combined therapy group was significantly higher than that of the concurrent chemoradiotherapy group with statistically significant differences (85.2% vs. 71.0%, χ2=4.33, P=0.037). There was no statistical difference (98.4% vs. 91.6%, P > 0.05) in the disease control rate (DCR) between the two groups. The combined therapy group had median PFS of 28.07 months and 1-, 3-, and 5-year PFS ratios of 78.2%, 37.5% and 29.1%, respectively. The concurrent chemoradiotherapy group had mPFS of 19.54 months and 1-, 3-, and 5-year PFS ratios of 72.9%, 28.3% and 21.3%, respectively. Both groups showed statistically significant differences in PFS (χ2=4.49, P=0.034). The combined group had median OS of 34.93 months and 1-, 3-, and 5-year OS ratios of 88.5%, 46.8% and 37.4%, respectively. The concurrent chemoradiotherapy group had mOS of 24.30 months and 1-, 3-, and 5-year OS ratios of 81.3%, 35.2% and 28.0%, respectively. Both groups showed statistically significant differences in OS (χ2=5.11, P=0.024), but did not show statistical differences (P > 0.05) in the severity degree of each adverse effect during the treatment.Conclusions Concurrent chemoradiotherapy combined with nimotuzumab can improve the ORR and prolong the PFS and OS of patients with inoperable ESCC compared with concurrent chemoradiotherapy alone. Furthermore, combining with nimotuzumab does not increase adverse effects and can be tolerated by patients with high safety. |
