Grade 1 raised ALT and/or AST referred to ALT and/or AST > 1xULN‐3xULN if baseline was normal; 1.5‐3x baseline if baseline was abnormal. Grade 2 raised ALT and/or AST referred to ALT and/or AST > 3xULN‐5xULN if baseline was normal; >3‐5x baseline if baseline was abnormal. Grade 3 raised ALT and/or AST referred to ALT and/or AST > 5xULN‐20xULN if baseline was normal; >5‐20x baseline if baseline was abnormal. Grade 4 raised ALT and/or AST referred to ALT and/or AST > 20xULN if baseline was normal; >20x baseline if baseline was abnormal. Grade 1 raised total bilirubin referred to total bilirubin > 1xULN‐1.5xULN if baseline was normal; >1‐1.5x baseline if baseline was abnormal. Grade 2 raised total bilirubin referred to total bilirubin > 1.5xULN‐3xULN if baseline was normal; >1.5‐3x baseline if baseline was abnormal. Grade 3 raised total bilirubin referred to total bilirubin > 3xULN‐10xULN if baseline was normal; >3‐10x baseline if baseline was abnormal. Grade 4 raised total bilirubin referred to total bilirubin > 10xULN if baseline was normal; >10x baseline if baseline was abnormal. During ICIs referred to the period from start of ICIs till 4 weeks after the last dose of ICIs.
Abbreviations: ALT = alanine aminotransferase, AST = aspartate aminotransferase, FU = follow‐up, G1 = grade 1, G2‐4 = grade 2‐4, ICIs = immune checkpoint inhibitors, TBili = total bilirubin, ULN = upper limit of normal.
Results are presented as N (%) of that cancer type.
Results are presented as n/N (%). The percentage represents the proportion among patients of that cancer type who had any raised ALT and/or AST during ICIs.
The four commonest types of other cancers included kidney cancer, breast cancer, skin cancer, and pharyngeal cancer.
