Prognostic Significance of the Tumor-Stromal Ratio in Invasive Breast Cancer and a Proposal of a New Ts-TNM Staging System
Figure 2
Differences between Kaplan–Meier plots for disease-free survival in each group calculated by the log-rank test. Low TSR (high stroma) was associated with worse 5-year disease-free survival (χ2 = 5.212, ). BC = breast cancer; TS = tumor-stromal ratio.
