Abstract

The aim of this study was to investigate whether Chalkley estimates of angiogenesis add new knowledge regarding prediction of prognosis in 455 consecutive early breast carcinomas, both node-positive (52%) and node-negative (48%). Median follow-up was 101 months. Intense vascularization indicated poor disease-specific (p = 0.003) and overall (p = 0.004) survival. In node-negative patients, Chalkley counts were not associated with prognosis, whereas in node-positive patients, high Chalkley scores indicated poor disease-specific (p = 0.0006) and overall (p = 0.0008) survival. A multivariate analysis showed that positive lymph nodes, high histopathological grades, and negative oestrogen receptors were independent markers of cancer-related death. A high histopathological grade was associated with cancer-related death in node-negative patients, whereas in node-positive patients, many lymph nodes, high malignancy grade, negative oestrogen receptor, and increasing Chalkley counts (both tertiles and continuous) were independent markers of disease-specific death. Thus, in a univariate analysis it was found that high Chalkley estimates of angiogenesis indicated a poor prognosis, but high Chalkley estimates were independent prognostic markers only in node-positive patients.
