HAVCR1 and diffuse large B-cell lymphoma: Among systemic DLBCL, Tim‐1 was positive in 9 (26.5%) of 34 germinal center B‐cell like (GCB) and in 8 of 55 non‐GCB DLBCL evaluated by immunohistochemistry based on Hans' algorithm 18, suggesting that Tim‐1 expression was not significantly biased to either cell of origin (P = 0.178).
