In this study, the incidence of CLNM in patients with [cN.
Previous studies have shown that larger tumor size was the risk factor for the presence of CLNM in patients with PTC [28-30].
The relationship between tumor bilaterality and CLNM in patients with PTC is still controversial.
The second limitation was that we could not evaluate the effect of occult CLNM identified by pCND on oncological outcomes of patients with [cN.
Ages <45 years, tumor size >2 cm, and bilaterality are independent risk factors of CLNM, which allow for selective CND in patients with [cN.
