The ΔKi67 was calculated as ΔKi67 = residual tumor Ki67 − CNB Ki67, with “substantial decrease” defined as a decrease of at least 40%, “moderate decrease” defined as a decrease of 20–39%, “small decrease/no change” defined as a decrease of 0–19%, and “elevation” defined as a higher residual tumor Ki67 than CNB Ki67. The gene discussed is MKI67; the disease is neoplasm.
