对３８例甲状腺髓样癌的外科治疗及预后因素作初步分析。在手术方式的比较中，一侧腺叶和峡部切除与近全叶切除两种术式比较；功能性颈清术与根治性颈清术比较，两组术后复发率差异均无显著性。本组５年和１０年生存率分别为７８．９％（１５／１９）和６２．５％（５／８）。影响预后的主要因素是原发癌侵犯程度及患者年龄。腺内型及４０岁以下者预后较好。 A preliminary analysis of the surgical treatment and prognostic factors of 38 cases of medullary thyroid carcinoma. In the comparison of surgical methods, one side of the lobe and isthmus resection compared with near total lobectomy; compared with functional neck dissection and radical neck dissection, there was no significant difference in the recurrence rate between the two groups. The 5-year and 10-year survival rates for this group were 78.9% (15/19) and 62.5% (5/8), respectively. The main factors affecting the prognosis are the degree of primary cancer invasion and the patient’s age. Intra-glandular and those under 40 years have a better prognosis.
