67Ga scanning and upper gastrointestinal series for gastric lymphomas.
67Ga scanning and upper gastrointestinal (UGI) series were performed in 13 patients with gastric lymphomas before any treatment was initiated. Seven of these patients also underwent both examinations after completing chemotherapy and/or radiation therapy. Prior to treatment, all 13 patients had abnormalities on the UGI examination, and 12 of them had abnormalities on the 67Ga scans. In 6 patients, more extensive gastric abnormalities were demonstrated by 67Ga scanning than by UGI examination. Although persistent 67Ga uptake after treatment was indicative of relatively poor therapeutic response, lack of uptake did not always indicate a good response to treatment.
