Abstract:
Objective To analyze the clinicopathologic characterizations and patients prognosis of basal-like breast cancer. Methods The clinicopathologic eharacterizations,patient 5 year disease-free survival rate and overall survival rate of 25 basal-like breast cancer patients were compared with 34 CerbB2 overexpressing subtype and 37 ER positive subtype breast cancer patients admitted in our hospital in the same period. Results Patients of basal-like breast cancer accounted for 15.7% of all patients admitted.Compared with CerbB2 over-expressing subtype(29.4%)and ER positive subtype(35.1%),basal-like breast cancer patients were eider with 56.0% being≥50 years old(P＜0.05).Basal-like subtype breast cancer was larger in tumor size than ER positive subtype(P＜0.05),56% of basal-like subtype were of poor-differentiated grade pathologically compared with 18% in CerbB2 overexpression type and 16% in ER positive subtype respectively. Meanwhile, axillary lymph node metastasis was hishbar in CerbB2 overexpressing and ER positive subtype(64.7%,64.9%)than that of basal-like subtype(40.0%).Most visceral metastases were found in basal-like and CerbB2 subtype,but there were more local lymph node and bone metastases in ER positive subtype.Five year overall survoval rate of CerbB2 overexpressing subtype (48.5%)and basal-like subtype breast cancer patients(44.1%)were poorer than that of ER positive subtype(83.8%).respectively;However,there was no difference in 5 year disease-free surviVal rate between the three subtypes(42.7%,40.4%,58.3%,respectively).Conclusions Similar to CerbB2 over-expressing subtype.tlle clinicopathologic characterization and prognosis in basal-like breast cancer are poorer than that in ER positive subtype.
