Differences and analogies in thyroid cancer discovered incidentally or by thyroid-related screening: a multicenter study

Eur Thyroid JPublished Retrospective cohort study

Authors' conclusion

biological features of TC are similar in the TD and ID groups, but patients in the two groups display significant differences regarding their clinical features.

Study context

Population
Consecutive patients with thyroid cancer, three hospital-based centers (Pavia, Latina, Messina), Italy
Participants
327 patients
Exposure
Incidental (ID) vs thyroid-related (TD) pre-surgery reasons leading to Thyroid-Cancer (TC) diagnosis
  • IDn = 65
  • TDn = 262reference
Outcome
Prevalence of TD vs ID pre-surgery reasons leading to TC diagnosis
Methodological detailsmulticentre, three high-volume hospital-based centers, Italy

  • Three high-volume hospital-based centers, Italy

Main finding

As reported in the abstract

Pre-surgery reason leading to TC diagnosis

Observational data: associations, not effects.

Further findings

Clinical characteristics and comorbidities

ID patients more frequently males, significantly older and with higher BMI than TD
ID had a higher rate of non-thyroidal cancers and cardiovascular/metabolic comorbidities

TC features: histotype, size, extra-thyroidal extension, lymph-node metastases, AJCC staging, ATA risk

No significant differences between ID and TD
