Surgical Management of Appendicular Skeletal Metastases in Thyroid Carcinoma
Figure 2
Kaplan-Meier analysis of patient survival. (a) Following surgery for osseous metastases patient survival was 72% at 1 year (95% CI 59–87%), 29% at 5 years (95% CI 17–49%), and 20% at 8 years (95% CI 10–42%). (b) There was better survival for patients when the metastastic osseous tumor was excised versus not excised. The median survival time for patients with tumor excision was 2 years (95% CI 1.4–5 years), compared with 0.6 years (95% CI 0.1–1.8 years) for patients without tumor excision (). No patient without tumor excision survived beyond 1.8 years. (c) Following thyroidectomy at initial diagnosis of thyroid carcinoma patient survival was 62% at 5 years (95% CI 48–80%), 35% at 10 years (95% CI 21–58%), 17% at 20 years (95% CI 7–41%), and 9% at 30 years (95% CI 2–32%). (d) After thyroid removal, patients who received radioactive iodine treatment had better survival than those who did not ().
