TILs in the sections of LLABCs, using H&E staining, at 400x magnification; (a) low level of lymphocytic infiltration; (b) high level of lymphocytic infiltration. Low level of TILs defined as ≤60% of tumour nests (Itu: intratumoural) and stromal areas (Str: stromal) infiltrated by lymphocytes. High level of TILs defined as >60% of tumour nests and/or stromal areas infiltrated by lymphocytes.
