  • a P < 0.01 (χ2 test).

  • b EPIL(+)ve = strong EPIL staining; EPIL(−)ve = absent to weak EPIL staining.

  • c c-erbB-2(−)ve = DAKO-score 0 to +1; c-erbB-2(+)ve = DAKO-score +2 to +3.

  • d Ki-67 (−)ve ≤ 25% immunoreaktive nuclei in one spot.

  • e Ki-67 (+)ve ≥ 25% immunoreaktive nuclei in one spot.
