title: Nm23 expression versus helix-pomatia lectin-binding in human breast-cancer metastases.
abstract: The relationship between nm23 expression, HPA staining, and other clinicopathological variables, i.e., axillary (AX) and internal mammary lymph node (IMN) metastases was assessed, and their prognostic values were analyzed. Positive HPA staining was found to be significantly correlated with tumor size, and with AX and IMN metastases, whereas negative nm23 expression was significantly correlated with AX and IMN metastases. A univariate study revealed that overall survival was correlated significantly with tumor size, AX and IMN metastases, and HPA staining, whereas nm23 expression did not appear to be a significant prognostic factor. In a multivariate study, only AX and IMN metastases were significant prognostic factors. When AX and IMN metastases were excluded from the Cox model, however, only HPA staining had independent prognostic value for survival. In this study, therefore, it may be concluded that HPA staining was more closely correlated with AX and IMN metastases, and with survival than nm23 expression.
