Immunohistochemical staining of TS, TP, and ERCC1 in oesophageal squamous cell cancer. (A) High staining intensity for TS. The TS staining was predominantly a cytoplasmic granular pattern ( × 400). (B) Positive sample with TP. The immunoreactivity was nuclear and cytoplasmic and it was highly expressed in mononuclear cells ( × 400). (C) High expression of ERCC1. The ERCC1 staining was strong and diffuse in the nucleus ( × 400).
