Patients and Methods: We retrospectively reviewed patients with breast cancer who underwent sentinel lymph node biopsy at our center from 2008 until 2012. IMN drainage was assessed as a potential risk factor for local and distant disease recurrence. Results: We identified 712 patients, with incidence of drainage to IMNs of 18.4%. No detrimental effect of the pattern of drainage to IMNs was found after a median follow-up of 58 months. A similar outcome was observed when drainage to IMNs was evaluated as a risk factor for patient survival. The potential risk factors for drainage to IMNs during sentinel lymph node biopsy were younger age (p=0.002) and tumor location in lower-outer, lower-inner, and upper-inner versus upper-outer quadrant (p<0.0001). Conclusion: The drainage to IMNs is unlikely to have a detrimental effect on patient outcome.
