Cumulative Kaplan-Meier survival curves based on the median values of Oct-4 immunochemical histoscores in NSCLC tissues are showed for all cases (A), and for adenocarcinoma (B), squamous cell carcinoma (C), MVD-negative (D), MVD-positive (E), VEGF-negative (F), and VEGF-positive (G) cases. All cases were divided into positive (above the median histoscore) and negative (below the median histoscore) groups. Oct-4-positivity was associated with decreased overall survival in all subset. Statistical differences were calculated using log-rank comparisons.
