Figure 4. — Correlation of ERCC1 expression in operable Xuanwei lung adenoma patient samples and the association of ERCC1 with patient survival. (A and B) Favorable overall survival and progression-free survival were associated with negative nuclear accumulation of ERCC1 (P<0.05). (C) The number of ERCC1 positive patients and IHC score of each case in the different stage groups. Increasingly more patients were detected as ERCC1-positive as the disease progressed (Chi-square test was applied for the analysis of ERCC1 positive rate. P<0.05). Stage IIIa patients had the highest IHC score. (Kruskal-Wallis test was applied for the analysis of IHC score of protein expression *P<0.05). (D) Typical patient samples of ERCC1 expression. Slides were stained with rabbit anti-ERCC1 antibody and visualized with goat anti-rabbit secondary antibody (magnification of ×400).
