The mutation rate of CD70 in the Chinese cohort was indeed significantly higher than that in the Swedish cohort (19.3% vs. 4.8%, χ2‐test, P < 0.0001), as well as the published Western DLBCL cohorts5, 32, 34, 35, 36 (ranging from 1.9% to 9.6%; Figure S2). Here, CD70 is linked to diffuse large B-cell lymphoma.
