We recently made a clinical study of the results of 131I-internal irradiation therapy performed on group I of 14 cases of metastatic lung tumor and group II of 12 cases of metastatic osteo-mediastinal tumor (of thyroid cancer origin), which we have experienced during a period of 7 years from May 1981 to May 1988. For the group I, of 4 cases of 131I-accumulated tissue, 1, 2 and 1 had remarkably effective, effective and ineffective benefits, respectively, and of 10 cases of non-131l-accumulated tissue, 2 and 8 had effective and ineffective benefits, respectively. For the group II, of 5 cases of 131I-accumulated tissue, 4 and 1 had effective and ineffective benefits, respectively, and of 6 cases of non-31I-accumulated tissue, 2 had effective benefits. Mean survival period was 7 years fo1r the group I and 2.5 years for the group II.
