Evaluation of trophoblast antigen protein 2 (TROP2) expression in primary tumor and liver metastases by immunohistochemistry (IHC). (A) Strong TROP2 expression in a primary tumor; (B) Moderate TROP2 expression in a primary tumor; (C) No TROP2 expression in a primary tumor; (D) Strong TROP2 expression in liver metastases; (E) Moderate TROP2 expression in liver metastases; and (F) No TROP2 expression in liver metastases. The original magnifications were 200× and 400× with a 100-μm scale.
