title: CD24 expression has a prognostic impact in breast carcinoma.
abstract: We investigated the prognostic significance of BAG-1 and CD24 in invasive breast carcinomas. Seventy cases of invasive breast carcinoma were studied immunocytochemically for the expression of BAG-1 and CD24. The results were correlated with several prognostic parameters, including 5-year survival. Univariate analysis showed a significant correlation of BAG-1 and CD24 overall positive staining with several adverse prognostic parameters, such as increased stage (p<0.0001), tumor grade 3 (p=0.016 and p=0.02, respectively), positive lymph nodes (p<0.0001), and increased tumor size (p<0.0001). Similar results were found for BAG-1 nuclear staining, as well as for positive cytoplasmic CD24 expression. Both of our markers studied had a significant, negative effect on survival. Multivariate analysis further revealed an independent prognostic impact for CD24 overall staining. The results of our study showed that overall cytoplasmic and especially nuclear BAG-1 expression, as well as overall and cytoplasmic CD24 expression, correlates with adverse prognostic parameters. An independent prognostic value for overall CD24 staining was also demonstrated.
