目的 分析分化型甲状腺癌的局部侵犯特点 ,探讨手术方法及疗效。方法 回顾总结本院 1993～ 2 0 0 2年手术治疗的 2 12例分化型甲状腺癌的临床资料。结果 110例 ( 5 1.9% )患者有颈部器官的侵犯 ,接受侵率的高低依次为颈前带状肌、颈段气管、喉返神经、颈段食管等 ,其中 10 4例行根治性手术 ,6例行姑息性手术 ,涉及气管、食管部分切除 4例 ,5年存活率和无瘤生存率分别为 91.6%、84.7%。结论 分化型甲状腺癌晚期可伴有广泛的颈部器官的侵犯 ,大多数可行癌肿根治性切除 ,行气管、食管扩大切除后仍能取得良好的治疗效果
Objective To analyze the characteristics of localized invasion of differentiated thyroid cancer and explore the surgical methods and efficacy. Methods The clinical data of 22 cases of differentiated thyroid cancer treated surgically in our hospital from 1993 to 2002 were retrospectively reviewed. Results 110 cases (51.9%) patients had cervical organ invasion. The invasion rate was followed by the anterior cervical ribbon, the cervical trachea, the recurrent laryngeal nerve, and the cervical esophagus. Among them, 104 patients underwent radical surgery. Six patients underwent palliative surgery, involving partial tracheal and esophageal resection. The five-year survival rate and disease-free survival rate were 91.6% and 84.7%, respectively. Conclusion The late stage of differentiated thyroid cancer may be accompanied by extensive neck organ invasion. Most of them are feasible for radical resection of cancer, and can still achieve good therapeutic effect after extended resection of trachea and esophagus.
