Erratum to: Difficulties in deciding whether to ablate patients with putatively “low–intermediate-risk” differentiated thyroid carcinoma: do guidelines mainly apply in the centres that produce them? Results of a retrospective, two-centre quality assurance study

Purpose We determined the reasons for radioiodine thyroid remnant ablation, and the procedure’s necessity based on postsurgical remnant size, in patients with putatively “low–intermediate-risk” differentiated thyroid carcinoma (DTC). We identified key clinicopathological, treatment and remnant characteristics, and factors associated with remnant size in 336 patients with pT1/2, M0 DTC ablated during the period September 2010 to October 2013 at one Cypriot or one Greek referral centre.
