131‐I treatment of micronodular pulmonary metastases from papillary thyroid carcinoma

Pulmonary metastases from papillary thyroid carcinoma shorten the survival of the hosts. Treatments with 131‐I have been reported to induce disappearance of these tumors in a large proportion of afflicted patients. In this study, consecutive patients with diffuse micronodular lung metastases from papillary thyroid carcinoma were examined to determine if disappearance of tumor occurred, and how much disappeared, after substantial amounts of 131‐I were administered.
