  • * Lymph node with tumor (+) or without tumor (−); grade, histologic grade 3 versus histologic grades 1, 2; tumor sizes >5 cm or fixed to the chest wall (sizes 3,4) versus tumor <5 cm in diameter (sizes 1, 2); for the rest of the tumor variables, the presence (+) or absence (−) of immunocytochemical staining using a cutoff of 5% of the carcinoma cells stained.

  • Number of patients with carcinomas either classified as staining (+, positive) or not staining (−, negative) for S100P. Parentheses show the percentage of patients.

  • Probability between paired samples from Fisher's exact test (two-sided value).
