Researchers found similar oncologic outcomes for low-risk papillary microcarcinoma managed with immediate surgery and active surveillance; however, immediate surgery was associated with more unfavorable events, according to recent study findings published in Thyroid.
“Even [papillary microcarcinomas] 1 cm or smaller in maximum diameter may be associated with lymph node metastases, distant metastases (although very rare), or invasion to the recurrent laryngeal nerve causing [vocal cord paralysis],” the researchers wrote. “These symptomatic [papillary microcarcinomas] have aggressive characteristics and should be treated appropriately. However, the vast majority of the [papillary microcarcinomas] incidentally detected during imaging studies do not show these aggressive features.”
