| Research Abstract |
Triple negative breast cancer observed high histological grade, further vascular invasion, high vascularization and proliferation potential. Results of our study demonstrated that triple negative breast cancer could be further sub-classified into three different groups (low, intermediate, high) according to the Risk Score System evaluating the following five prognostic variable (pathological tumor size, pathological node status, basal-like type, Ki67 labeling index and Microvessel Density). Difference was observed in the survival rate significantly in these three groups. In conclusion, this classification is useful as a therapeutic decision-making tool for triple negativepatients.
