外文摘要：Neoadjuvant PD-1 inhibitor is promising in cutaneous melanoma but remains unknown in acral melanoma(AM).This phase lb trial study(Clinicaltrials.gov NCT04197882)assessed the efficacy and safety of the combination of neoadjuvant oncolytic virus orienX0l0(ori)and anti-PD-1 toripalimab(tori)for resectable AM.Thirty patients of stage Ⅲ/Ⅳ received neoadjuvant therapy of ori and tori for 12 weeks before surgery,followed by adjuvant treatment with tori for 1 year.Primary endpoints were radiographic and pathological response rates,with secondary endpoints of 1-and 2-year recurrence-free survival(RFS)rates,event-free survival(EFS)rates,and safety.Twenty-seven completed surgery and tori adjuvant treatment and median follow-up was 35.7 months.Radiographic and pathological response rates were 36.7％and 77.8％,with complete response rates of 3.3％and 14.8％,1-and 2-year RFS rates of 85.2％and 81.5％,and 1-and 2-year EFS rates of 83％and 73％,respectively.Adverse events occurred in all patients,mainly grade 1-2.There was no correlation between PET/CT evaluation and pathological response or progression-free survival/overall survival.Patients with pathological response showed tumor beds with high tertiary lymphoid structures(TLSs)and tumor-infiltrating lymphocytes(TILs).Cytokines and chemokines analysis showed the combination therapy significantly increases the secretion of proinflammatory cytokines and chemokines in both responders and non-responders.Therefore,neoadjuvant ori and tori demonstrated promising antitumor activity with high response rates and high 2-year RFS/EFS for AM with acceptable tolerability.
