Echographic evaluation of abdominal tumor regression during antineoplastic treatment

Twenty patients with malignant abdominal tumors were evaluated by compound contact B‐mode ultrasonic scanning. The studies were carried out during and after antineoplastic treatment with chemotherapy, radiation or surgery. Gain and sensitivity settings were kept constant before and after treatment. The changes in echographic findings were correlated with clinical, laboratory and/or autopsy findings. Ultrasound proved to be a very useful and convenient way to evaluate the antitumor effect of various chemotherapeutic agents. Typical echograms are shown to illustrate the method of ultrasonic evaluation.
