Paper Abstract

In this retrospective cohort study, we examine the hypothesis that baseline oxygen saturation (SO2%) in contralateral normal tissue can be a quantitative measurement for predicting tumor response to neoadjuvant chemotherapy (NAC). Using our dynamic custom-built dual breast dynamic diffuse optical tomography (DOT) imager, we reconstructed SO2% measurement concentration for 12 stage II or III breast cancer patients. Six patients achieved pCR (RCB-0) and the other half had extensive residual disease (RCB-III). Baseline SO2% in contralateral normal tissue was statistically significantly higher in RCB-III subjects than in pCR (p = 0.025). From ROC analyses, baseline SO2% in contralateral normal breast tissue was able to discriminate pCR from RCB-III patients (AUC 0.889) with sensitivity and specificity of 83%.
