Abstract
Objective:
To study the significance of histological grading as a prognostic factor in breast cancer.
Methods:
According to the grading systems of Bloom-Richardson and Elston, 476 cases of invasive ductal carcinoma (IDC) with more than 5 year follow-up were assessed for grade I (GI, 72 cases), grade II (G II, 216 cases) and grade III (G III, 188 cases).
Results:
The 5 year survival rate for IDC G I, G II and G III were 81.9% (59 cases), 63.4% (137 cases) and 49.5% (93 cases) respectively.
Conclusion:
Histological grading of IDC is as good a prognostic factor as their clinical stage.
