At present, the risk factors for distant recurrence among patients with early ipsilateral breast tumor recurrence (IBTR) require further investigation. Early IBTR is defined as occurring within 3 years following the initial surgery. In the current study, 40 patients with early IBTR were examined to determine the risk factors for distant recurrence. A node-positive status at the time of primary surgery and the administration of adjuvant chemotherapy following the primary surgery were significantly correlated with poorer distant disease-free survival (P=0.001 and P=0.002, respectively). Multivariate analyses revealed that the nodal status at the time of primary surgery was an independent predictive factor for distant recurrence (P=0.050). Therefore, the results of the current study revealed that the nodal status at the time of primary surgery was an independent predictive factor for distant recurrence among patients with early IBTR.
