The effect of tumor size and lymph node status on breast carcinoma lethality

Abstract

The Size+Nodes method was shown to be capable of accurately estimating the risk of death due to invasive breast carcinoma from information on the size of the primary tumor and the number of positive lymph nodes. In addition, this method was used to stratify women into groups according to breast carcinoma lethality. In contrast, classification of women according to lymph node positivity, T status, or disease stage created groups with wide and overlapping levels of lethality.
