Abstract

PURPOSE:

Prognostic comparison of phosphohistone-H3 (PPH3) with Cytokeratin 5/6 and/or 14 positive (=basal-CK), triple (ER, PR, HER2)-negative (=TNP) and basal-like (=TNP and basal-CK positive) phenotype in invasive breast cancers.

PATIENTS AND METHODS:

Classical variables, PPH3, ER, PR, basal-CK and HER2 in 240 T1-2N0M0 patients under 71 years.

RESULTS:

TNP and basal-like cancers had higher PPH3 expression than the other cancers (mean 48 versus 11, P<0.001). Fifteen percent of the patients in the whole group, but 32-38% of TNP and basal-like cancers recurred. With multivariate analysis, PPH3<13 (n=156) versus >or=13 (n=84=35% of all cases) was the strongest and only prognosticator (10-year survival 96% and 64%, P<or=0.001, Hazard ratio=9.0).

CONCLUSION:

PPH3 is the strongest prognosticators in luminal, Triple negative and basal-like T1-2N0M0 invasive breast cancers.
