Negative Expression of Melanoma Cell Adhesion Molecule (MCAM) Correlated with Axillary Lymph Node Metastasis in Triple Negative Breast Cancer
Journal Title: Indonesian Journal of Clinical Pharmacy - Year 2016, Vol 5, Issue 3
Abstract
Triple negative breast cancer (TNBC) is breast cancers that demonstrate the absence of oestrogen receptor, progesterone receptor and human epidermal growth factor receptor 2. TNBC has an aggressive behaviour, high frequency of metastases to the axillary lymph nodes and recurrence, and poor prognosis. Metastasis to the axillary lymph nodes will affect the rate of survival and recurrence in TNBC. Melanoma cell adhession molecule (MCAM) is a membrane glycoprotein of the immunoglobulin superfamily, which is involved in the cells binding, which later became known as the marker for the progression and metastasis of melanoma and carcinoma of the prostate. However, MCAM role in mammary carcinoma still kontroversial. The aim of this study was to assess correlation between MCAM expression with incidence of metastatic to axillary lymph nodes in TNBC. This research was conducted during January 1st 2010–April 31st 2015 at Pathology Anatomy, Faculty of Medicine, Universitas Padjadjaran. This study used a cross-sectional design, using lambda correlation test. MCAM immunohistochemical staining performed on 56 samples of paraffin blocks of TNBC group that did not metastasized and has metastasized to the axillary lymph nodes. A total of 22 of 28 (78.6%) of TNBC metastatic to axillary lymph nodes have histoskor MCAM value <4 (negative), whereas 16 of 28 (57.1%) of TNBC non metastatic have histoskor value ≥ 4 (positive). Negative expression of MCAM correlated with TNBC that had metastasized to axillary lymph nodes, although not the only factor that influenced them.
