TACSTD2, tumor‐associated calcium signal transducer 2; BAC, bronchioloalveolar carcinoma; mixed BAC, adenocarcinoma of mixed subtype with BAC component; non‐BAC, adenocarcinoma without BAC component; type A, B, C, D, E, and F, see definitions in Materials and Methods section. If more than 10% of tumor cells were strongly stained, this was taken as positive staining.
