Regarding OS, patients with a percentage of melanoma cells expressing IFNAR1 of ≤ 35% had a median OS of 31.0 months (range: 19.8–42.2 months), while patients with a percentage of stained melanoma cells expressing IFNAR1 of > 35% had a median OS of 5.0 months (p = 0.02) (Fig. 5b). Here, IFNAR1 is linked to melanoma.
