The goal of our study was to evaluate whether pre- and post-chemotherapy nodal volume affects the survival profiles of breast cancer patients. In addition, we also evaluated these effects with respect to responders and non-responders to neoadjuvant chemotherapy. Comparison was made by analyzing the effects of tumor volume on survival profiles. We concluded that recurrence-free survival profile is dependent on axillary lymph node volume, and that non-responder patients with large nodes may need more vigorous treatment and follow up as they were associated with worse recurrence-free survival.
