Authors' conclusion

Our study demonstrates a continuum of disease-specific risk of PTC, pointing at PTCtcf as an intermediate entity between tcPTC and classic PTC.

Study context

Population
Consecutive patients with tcPTC and PTCtcf evaluated at a tertiary academic referral center 2005–2020, plus a comparative cohort of classic PTC
Participants
