CQ20. When Can Papillary Microcarcinoma (Papillary Carcinoma Measuring 1 cm or Less) Be Observed Without Immediate Surgery?

Treatment of Thyroid Tumor

Abstract

In the past, papillary microcarcinoma was divided into only three categories based on the circumstances of discovery: latent carcinoma (detected on autopsy for reasons other than thyroid carcinoma: prevalence up to 36%), incidental carcinoma (detected on pathological examination for surgical specimens of benign thyroid diseases: the prevalences were reported to be 1.3–22%), and occult carcinoma (lymph node metastasis and/or distant metastasis are detected in advance and small primary lesions in the thyroid are detected thereafter, which is very rare). However, recently, the incidence of microcarcinoma in the clinical setting drastically increased because of the prevalence of mass ultrasonography screening and the development of the fine needle aspiration (FNA) biopsy technique. The prevalence of latent microcarcinoma accounts for 10% of the general population, while the morbidity rate of clinical carcinoma is less than 0.1% and papillary carcinoma shows a generally good prognosis, facilitating a trial observation of incidentally detected microcarcinoma without immediate surgery.
