Multispectral and phase-contrast diffuse optical tomography are used to track treatment progress in a patient with locally
advanced invasive carcinoma of the breast cancer during neoadjuvant chemotherapy. Two types of chemotherapy
treatment including four cycles of Adriamycin/Cytoxin (AC cycles) and twelve cycles of Taxol/Herceptin (TH cycles)
were applied to patient. A total of eight optical exams were performed before and within the chemotherapy. Images of
tissue refractive index, and absorption and scattering coefficients, as well as oxy-hemoglobin and deoxy-hemoglobin
concentrations along with scattering particle volume fraction and mean diameter of cellular components were all
obtained. The tumor was identified through absorption and scattering images. Tumor shrinkage was observed during the
course of chemotherapy from all the optical images. Our results show that oxy-hemoglobin, deoxy-hemoglobin and total
hemoglobin in tumor decreased after chemotherapy compared to that of before chemotherapy. Significant changes in
tumor refractive index along with tumor cellular morphology during the entire chemotherapy are also observed.
