Management of lung and bone metastases from thyroid cancers of differentiated structures

During a period of thirty years (1959-1989) 374 patients underwent surgery for differentiated thyroid carcinoma at the 1st Department of Surgery of the University Medical School in Debrecen. Distant metastases were found in the lungs or bones in 36 patients (9.6%). In 20 patients the first clinical sign of the primary disease was the distant metastasis. The aspects of surgical treatment depended on whether the metastases were solitary or multiple, capable or uncapable of radioiodine uptake. Whereas the majority of pulmonary metastases respond well to 131I-treatment the therapy of bone metastases is multidisciplinary. The 5-year survival rate was 47%, the 10-year one 19%.
