We reviewed the clinical and pathologic data of the 135 cases with occult carcinoma of the thyroid (OCT) between 1962 and 1991. 54 cases were found incidental to thyroid operation (group I), 77 cases were found primarily by cervical node metastasis (group II), 3 were found at the time of operation for other tumors of the head and neck and 1 was traced by distant metastasis. All patients were treated surgically in our service. Mean follow-up period was 10 years. None of patients died from causes related to OCT in group I. 6 cases died of the cancer in group II, hence a 10-year survival of 81.25%. Based on our clinical observations, OCT could be divided into two types. Type I is that found incidentally by thyroidectomy which usually with good prognosis. Type II which was evidenced by nodal metastasis tends to follow a poor postoperative course.
我们回顾了1962年至1991年间135例甲状腺隐匿癌（OCT）的临床和病理资料。54例是在甲状腺手术中偶然发现的（第一组），77例主要是通过颈部淋巴结转移发现的（第二组），3例是在头颈部其他肿瘤手术时发现的，1例是通过远处转移追踪到的。所有患者均在我院接受了手术治疗。平均随访期为10年。第一组中没有患者死于与OCT相关的原因。第二组中有6例死于癌症，因此10年生存率为81.25%。根据我们的临床观察，OCT可分为两种类型。I型是在甲状腺切除术中偶然发现的，通常预后良好。II型以淋巴结转移为证据，术后病程往往较差。
