Objective To study the clinicopathologic characteristics of triple-negative breast cancer (TNBC) and its value in the prediction of prognosis. Method In this study,500 cases of female breast cancers were examined immunohistochcmically for the TNBC. The clinicopathologic characteristics of the 243 TNBC cases were inspected. Results TNBC accounted for 17.6% (88/500) of the 500 breast cancers. The histological types of the TNBC included mainly infihrative ductal carcinoma, metaplastic carcinoma and medullar carcinoma. Among those, histological grade Ⅲ accounted for 72.7% (64/88) of all the TNBC and was more common than that in hormone receptor positive breast cancers (HR+ group ) and Her-2 overexpression breast cancers (Her-2 group)(P=0.000). The positive rates of CK5/6 and EGFR in the TNBC were 30.7% (27/88) and 34.1% (30/88), respectively. The positive rates of ERCC1 and KIT in the TNBC were 28.4% (25/88) and 34.1% (30/88), respectively, Both of which were higher than those in the HR + group and Her-2 group, respectively (P=0.032 and P=0.026). 3-year survival rate of the TNBC was 71.5% and it was lower than that of HR group (P=0.021) and not significantly different from that of Her-2 group (P=0.474). Conclusions TNBC is the breast cancer with high aggressive pathologic futures and poor prognosis. EGFR and ERCC1 expression were positive in a portion of TNBC cases.

Positive sentinel lymph node biopsy predicts the number of metastatic axillary nodes of breast cancer

It remains to be clarified whether a positive sentinel lymph node biopsy (SLNB) can predict the number of metastatic axillary nodes. This study examined a consecutive series of women with unilateral invasive breast cancer who underwent axillary lymph node dissection after an intra-operative positive SLNB. The numbers of positive and negative sentinel lymph nodes (SLNs) were analyzed for a likelihood of pN1a, pN2a, and pN3a diseases as per the UICC TNM classification. Of the 368 study patients, 165 (45%) had one positive SLN and one or more negative SLNs. This result represented the most common combination of positive and negative SLNs. It was also the most predictive indicator (93%) of pN1a disease and the least predictive indicator (7% or 0%) of pN2a or pN3a disease, respectively. The numbers of positive and negative SLNs can predict the number of metastatic axillary nodes in breast cancer patients.
