Researchers develop tech to predict chemotherapy effectiveness ANI | Updated: Jun 04, 2021 02:06 IST Washington [US], June 4 (ANI): Combining data from tumor biomarkers, ultrasound, and ultrasound-guided diffuse optical tomography (DOT) after a patient's first cycle of pre-surgical neoadjuvant chemotherapy provided a highly accurate prediction of how the tumor was responding to the treatment, finds an interdisciplinary team of researchers at Washington University in St.Louis. While early detection of breast cancer is critical, early prediction of how well the neoadjuvant chemotherapy treatment before surgery is working also may provide a window of opportunity when treatment could be altered and have a big impact on the patient's quality of life.
