- Abstract: Objective To investigate the effect of toripalimab combined with chemoradiotherapy in patients with cervical lymph node metastasis of nasopharyngeal carcinoma on immune function.Methods A prospective study was conducted in 160 patients with nasopharyngeal carcinoma accom-panied by cervical lymph node metastasis.Patients were divided into study group and control group using block randomization,with 80 patients in each group.The control group received a standard che-moradiotherapy regimen,while the study group received toripalimab combined with chemoradiothera-py.Both groups were treated for 3 courses.The clinical efficacy,levels of immune function indica-tors,levels of tumor markers[squamous cell carcinoma antigen(SCC-Ag),high-mobility group box 1(HMGB1),pentraxin 3(PTX3),and cytokeratin 19 fragment antigen 21-1(CYFRA21-1)],and the incidenceof adverse reactions were compared between the two groups.Results The objective re-sponse rates of the primary lesion and cervical lymph nodes in the study group were higher than those in the control group(P＜0.05).After treatment,the levels of CD3+,CD4+,and natural killer cells in the study group were higher than those before treatment and in the control group,while the lev-el of CD8+was lower than that before treatment and in the control group(P＜0.05).After treatment,the levels of HMGB1,PTX3,SCC-Ag and CYFRA21-1 in the study group were lower than those before treatment and in the control group,and the differences were statistically significant(P＜0.05).There was no statistically significant difference in the incidence of adverse reactions between the two groups(P＞0.05).Conclusion Toripalimab combined with chemoradiotherapy has a sig-nificant efficacy in treatment of cervical lymph node metastasis of nasopharyngeal carcinoma.It can enhance the immune function of patients,improve the levels of tumor markers,and has good safety.
