Objective:
To analyze the recurrence characteristics of triple-negative breast cancer (TNBC) and explore their clinicopathological correlations in northern China.
Methods:
Regression analyses were performed for 4 579 breast cancer patients from September 2002 to September 2007. Among them, there were 787 TNBC patients.
Results:
The median follow-up period was 72 (9-116) months. And 187 (23.8%) TNBC patients recurred and it was significantly different from the recurrence rate of non-TNBC group (17.4%, P = 0.024). The median time to recurrence was 30.2 (4-110) months and 36.3% recurred 2 years while 27.8% did within 2-3 years. The rates of lung, liver and brain metastases to other sites were higher in TNBC patients than those in non-TNBC patients. TNBC patients had higher local recurrence rates than non-TNBC counterparts (2.92% vs 1.56%) (P = 0.009). Age, regional lymph node infiltration, tumor size and pathological stage were all independent prognostic factors of TNBC.
Conclusion:
TNBC has unique recurrence characteristics. It is prone to recur shortly with a high local recurrence rate. Metastatic rate is higher in visceral organ than bone.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
