摘要: The Neoadjuvant response index (NRI) has been proposed as a simple measure of downstaging by neoadjuvant treatment in breast cancer. It was previously found to predict recurrence-free survival (RFS) triple-negative (TN) at least accurate the standard binary system, absence or presence pathological complete remission (pCR), which is commonly employed outcome measure. NRI evaluated an independent consecutive series patients validate previous findings. Univariable and multivariable analyses were done assess predictive value clinical parameters for RFS. We combined original validation build model RFS after chemotherapy TN set (N = 108) confirmed that with higher-than-median (>0.7) had excellent (P 0.002), similar who achieved pCR. Multivariable analysis 191 showed strong predictor 0.0002), N-stage 0.001) T-stage 0.014) ranking second third, respectively. Importantly, among did not achieve pCR (NRI values below 1), higher still associated better method practical tool cancer treated chemotherapy. adds prognostic information could be useful compare efficacies different regimens.
