Occult Axillary Lymph Node Metastases Discovered by Serial Section in Node Negative Breast Cancer
Karalak A Mail, HomchaEm P

Serial sectioning of the axillary lymph nodes from lymph node negative breast cancer
patients is presented. All patients were admitted between 1997-1998 and underwent mastectomy
and axillary node dissection. The histological examination revealed micrometastases in 5 (10%)
of 50 breast cancer subjects. The detection of these micrometastases in lymph nodes may identify
a high-risk node-negative population. The time and money that was spent to detect the micrometastases
was too high to perform it in every case. The clinician should be aware of the occult
micrometastases in node-negative cases.
Key word : Occult Metastases, Breast Cancer, Axillary Lymph Node
