Radiation therapy is useful in the palliative treatment of large, unresectable abdominal and pelvic malignancies. The purpose of this study is to evaluate the effectiveness of B mode ultrasound scanning as an adjunctin radiation treatment planning of these patients. Fifty‐one patients with large abdominal or pelvic masses had radiation therapy ports established using findings from surgery, radiographs, and physical examination. All the patients then had B mode ultra sound examinations. The position of the therapy ports was marked on the echogram. Thirty‐one of the 51 patients studied (61 percent) had evidence of extension of tumor beyond the therapy ports. This was often due to “iceberging”, i.e. when the deep portion of the tumor was considerably larger than the palpable margins of the superficial portion. B mode ultrasound scanning is a valuable adjunct in planning palliative radiation therapy of patients with large, unresectable, abdominal and pelvic malignancies.
