Patients with high CLEC3B mRNA expression showed an improved OS when compared to CLEC3B low expression (p<0.001, HR: 1.35); a similar observation was made in patients treated with checkpoint inhibitors (p<0.001, HR: 1.29)...Our study represents the largest analysis of CLEC3B mRNA expression in NSCLC. High CLEC3B expression levels are linked to a distinct molecular/immunological profile and to improved survival.
