Abstract:
Objective Through the analysis of the clinicopathological features of triple-negative breast cancer(TNBC),the relationship between recurrence,metastasis,the location of metastatic lymph nodes and primary lesions in breast cancer patients with TNBC was investigated. Methods The clinical data of 763 patients with TNBC from December 2008 to December 2012 in our hospi-tal were retrospectively analyzed. Results The onset average age of TNBC breast cancer was 49 years old,and 84. 7% of patients with early stage. The recurrence and metastasis rates of lymph node-positive patients were significantly higher than those of lymph node-negative patients,and increased the number of lymph nodes(P<0. 001). In the patient with negative for lymph nodes,the pri-mary tumor recurred in the inner quadrant and the metastasis rates were the highest(9. 8% and 13. 7% )(P<0. 05). Univariate anal-ysis showed that lymph node status,surgical procedure,and radiation dose were factors influencing recurrence and metastasis in pa-tients with TNBC(P<0. 05). Multivariate analysis showed that clinical stage and lymph node status were independent risk factors for recurrence of TNBC. Clinical stage and surgical approach were independent risk factors for the metastasis of TNBC ( P <0. 05). Conclusion (1)The proportion of patients with TNBC at early stage is high. The main pathological type is invasive ductal carcino-ma,and the positive expression rate of ki67 is high. (2)The prognosis of patients with positive lymph nodes was related to the number of metastatic lymph nodes,and there was not significant correlated with the location of primary tumor. For patients with negative lymph nodes,the primary tumor was located in the inner quadrant with the highest recurrence and metastasis rates. (3)The recurrence rate of TNBC patients increased with the increase of BMI,but for obese patients,the recurrence rate decreased. (4)Lymph node status,clini-cal stage,surgical procedure,and radiotherapy dose all affect recurrence and metastasis of patients with TNBC. (5)Clinical stage and lymph node status are independent risk factors for the recurrence of TNBC. Clinical stage and surgical approach are independent risk factors for the metastasis of TNBC.
