OBJECTIVES: We aimed to analyze the factors that affect the axillary lymph node involvement in Turkish breast cancer patients with clinically non-palpable axillary lymph node.
BACKGROUND: Sentinel lymph node biopsy is the gold standard technique to evaluate the axillary lymph node status that directly influences the prognosis and the treatment options in breast cancer.
METHODS: Breast cancer patients without axillary lymph node involvement in clinic examination were enrolled the study. Patients were categorized into the two groups according to existence of axillary lymph node metastasis or not. Demographic, histopathological and clinical data of patients were revealed retrospectively.
RESULTS: One-hundred and eighty-seven patients were analyzed and 101 of patients fulfilled the criteria and were included the study. Metastatic lymph node was detected in 38 (37.6 %) patients (Group 1), and was negative in 63 (62.4 %) patients (Group 2). Sentinel lymph node metastasis were statistically significant higher in patients with Ki-67 ≥ 14 % than patients with Ki-67 < 14 % (51.9 % vs 22.4 %; p < 0.01). Likewise, the mean size of the sentinel lymph node was statistically significant higher in Group 1 compared to Group 2 (p < 0.01).

CONCLUSION: Ki-67 proliferation index and sentinel lymph node size may provide a higher prediction about the sentinel lymph node involvement in patients with clinically negative axillary lymph nodes (Tab. 3, Fig. 1, Ref. 31).
