New ultrasound could predict chemo success in weeks, not months

This study tests whether a special ultrasound technique, called contrast-enhanced subharmonic ultrasound, can predict if chemotherapy is working for stomach cancer that has spread to the liver. Currently, doctors wait about 2 months for CT or MRI scans to see tumor shrinkage. This ultrasound looks at blood flow inside liver tumors before and after 1-2 chemo cycles. The goal is to see if early changes in blood flow can predict later treatment success. The study will enroll 107 adults with newly diagnosed liver metastases who have not yet started treatment.
