Abstract
"Aim: Incidence of thyroid cancer worldwide is rising rapidly with increased detection of small incidental thyroid lesions. The aim of this study was to determine whether this trend is occurring in our practice in the Northern UK.
Method: All thyroidectomy operations over 5 years, in a single centre was generated from pathology records, and electronic patient records were reviewed to obtain details on pathology, imaging and mode of presentation.
Result: A total 298 patients underwent thyroid surgery of which 58(19.5%) had a histologically confirmed thyroid cancer. The subtypes of cancer were papillary (n=48(83%)), of which 17(29%) were microcarcinoma(<1cm), follicular (n=6(10%)) and medullary thyroid cancer(n=1(2%)). The majority were female (83%). 38(66%) presented symptomatically and 20(33%) were incidentally found on imaging or pathology. Thyroidectomy performed for Graves’ disease accounted for 11(19%) cancers and lesions found incidentally on imaging accounted for 9(16%). Out of 54 patients with Graves’ disease11(20%) had a histological diagnosis of papillary thyroid cancer.
Conclusion: Thyroid cancers detected through symptomatic presentation represent the majority in our practice. A third of cancers presented incidentally and approximately1/4 of all cancers are<1cm. A significant proportion of our thyroid cancers are small and incidentally found. It is not clear whether these incidental thyroid cancers would progress untreated to clinically apparent disease."
