甲状腺癌再次手术72例临床分析

目的分析甲状腺癌再次手术原因,探讨再次手术的时机和方式。方法回顾性分析2003年6月至2006年8月间收治的72例甲状腺癌再次手术患者的临床资料。再次手术原因主要为首次手术不当致肿瘤残留、肿瘤复发或颈淋巴结转移和^131Ⅰ治疗前的甲状腺清除。再次手术方式：病灶≤2cm的单个肿瘤,行患侧加峡部切除;其余行双侧甲状腺全切;怀疑及确诊为淋巴结转移者,加选择性颈淋巴结清扫术。结果术后病理证实,腺体肿瘤残留率47．1％（32／68）,淋巴结肿瘤残留率81．4％（35／43）。术后暂时性和永久性喉返神经损伤发生率分别为5．6％（4／72）及1．4％（1／72）。暂时性和永久性甲状旁腺损伤发生率分别为26．4％（19／72）及1．4％（1／72）。结论对于有肿瘤残留或复发的甲状腺癌患者,再次手术是必要的。最佳手术方式是双侧甲状腺全切加中央组淋巴结清扫和术中冰冻切片检查。

Outcome of reoperation for thyroid cancer: clinical analysis of 72 cases

OBJECTIVE: To analyze the indication of reoperation of thyroid cancer and to explore the timing, surgical pattern of reoperation. METHODS: Protocols of 72 patients underwent reoperation of thyroid cancer from June 2003 to August 2006 were reviewed retrospectively. Causes for reoperation were as follows: residue of the tumor locally as the inappropriate initial operation; local recurrence and cervical lymph node metastasis; before (131)I ablation which differentiated thyroid cancer with distant place metastasis. The reoperational style included residual lobectomy plus isthmus with single tumor below 2 cm, total thyroidectomy in most the other conditions and selective lymph node dissection in finding or suspected cervical lymph node metastasis. RESULTS: The rate of residual in thyroid confirmed by postoperative pathology was 47.1% (32/68). The rate of residual in cervical lymph node was 81.4% (35/43). The rates of temporary and permanent laryngeal recurrent nerve injury were 5.6% (4/72) and 1.4% (1/72) respectively. The rates of temporary and permanent hypocalcemia were 26.4% (19/72) and 1.4% (1/72) respectively. CONCLUSIONS: Inadequate operation, local recurrence and cervical lymph node metastasis of thyroid cancer need revision surgery undoubtedly. The optimal treatment was total thyroidectomy and level VI, VII central compartment lymph node dissection plus intraoperative frozen-section evaluation.
