Rational reflection and speculation： current diagnosis and treatment strategies for papillary thyroid microcarcinoma

甲状腺微小乳头状癌（PTMC）发病率呈全球化激增,故其诊治近年来倍受重视并引发争议。目前国内外部分学者对PTMC提出了两种诊治策略：＂过度诊断,过度治疗＂与＂主动观察,延迟干预＂。但结合PTMC的特点、患者意愿、医疗环境及医疗资源诸方面综合评估,＂主动观察,伺机干预＂是目前为止PTMC的最佳处理方式。

In recent years, the rapid increase in incidence of papillary thyroid microcarcinoma （PTMC） worldwide has spurred great attention and even disputes in its diagnosis and treatment. At present, two strategies for diagnosis and treatment of PTMC have been proposed by some scholars at home and abroad： one is ＂overdiagnosis and overtreatment＂, and the other is ＂active surveillance and delayed intervention＂ However, by taking an integrated account of the characteristics of PTMC, patients＇ preferences, and medical circumstances and resources, ＂active surveillance and opportunistic intervention＂ is considered to be the best strategy to date.
