Abstract:
Objective To explore the short-term efficacy and safety of programmed death receptor-1(PD-1)antibody combined with chemoradiotherapy in early high-risk nasal extranodal natural killer/T cell lymphoma(ENKTCL,Nomogram modified risk index ≥1).Methods This study was a prospective phase Ⅱclinical study.A total of 20 patients with stage Ⅰ/Ⅱ nasal ENKTCL initially treated in the Affiliated Hospi-tal of Guizhou Medical University from June 2021 to December 2023 were selected as the study subjects.They were given 3 cycles of PD-1 antibody+P-Gemox(pegaspargase+gemcitabine+oxaliplatin)regimen induced immunochemotherapy and 3 cycles of PD-1 antibody concurrent immunoradiotherapy,14 d/cycle.The com-plete response(CR)rate after 3 cycles of induced immunochemotherapy,CR rate after treatment,objective re-sponse rate(ORR)after 3 cycles of induced immunochemotherapy and ORR after comprehensive treatment,occurrence of adverse reactions and plasma Epstein-Barr virus DNA copy number were observed.Results Af-ter 3 cycles of induction immunochemotherapy,the CR rate was 35.0%(7/20)and ORR was 90.0%(18/20).After the concurrent immunoradiotherapy,the CR rate was 95.0%(19/20)and ORR was 100.0%(20/20).The adverse reactions were mainly the grade 1/2.the immune-related adverse reactions included 9 ca-ses of grade 1/2 hypothyroidism(45.0%),4 cases of grade 1 capillary vessel hyperplasia(20.0%),1 case(5.0%)of grade 2 infusion reaction,and no immune myocarditis occurred.All 7 cases of positive EBV DNA turned to negative after 3 cycles of induced immunochemotherapy.Conclusion PD-1 antibody combined with P-Gemox in the radiotherapy of early high-risk ENKTCL has a high short-term remission rate with good tol-erance for treatment.
