Fig.5From: Standardization of evaluation method and prognostic significance of histological response to preoperative chemotherapy in high-grade non-round cell soft tissue sarcomasKaplan–Meier estimate of overall survival by histological response. When the cut-off value of the percentage of the residual tumor area was set as 25%, the p-value for the difference in OS showed the minimum value. Hazard ratio of the non-responder (n = 39), whose percentage of the residual tumor was more than 25%, to the responder (n = 25) was 4.029 (95% CI, 0.893–18.188, p = 0.070)Back to article page
