甲状腺乳头状癌是甲状腺癌中的最常见的类型,约占成人甲状腺癌的60%左右和儿童甲状腺癌的全部。诊断甲状腺乳头状癌一般情况下不难,但微小乳头癌有时却容易被忽视。甲状腺乳头状微小癌是指瘤体最大直径≤1.0 cm的甲状腺乳头状癌的特殊亚型[1]。此类肿瘤不一定必然发展成为具有临床危害性疾病。即使有区域淋巴结转移,仍缺乏高危险性因素,对病人的生命不足以构成绝对威胁。所以本综述对于如何区分此肿瘤组织学特性与生物学行为以及制定相应的治疗原则予以进一步探讨。
Papillary thyroid carcinoma is the most common type of thyroid cancer, accounting for about 60% of adult thyroid cancer and thyroid cancer in children all. Diagnosis of thyroid papillary carcinoma is not difficult under normal circumstances, but sometimes tiny papillary carcinoma is easily overlooked. Small thyroid papillary carcinoma refers to the tumor of the largest diameter ≤ 1.0 cm of thyroid papillary carcinoma of the special subtype [1]. Such tumors do not necessarily develop into clinically hazardous diseases. Even with regional lymph node metastasis, the lack of high-risk factors, the patient’s life is not an absolute threat. Therefore, this review will further explore how to distinguish between the histological features and biological behavior of the tumor and the corresponding treatment principles.
