“…3,5 Risk, in the context of thyroid cancer, can be interpreted in various ways, and one individual's interpretation of low risk may be different from another's. 6 Thyroid cancer risk can be considered in terms of disease-specific mortality or risk of recurrence. 7,8 The Union for International Cancer Control/American Joint Committee on Cancer staging systems are designed to predict mortality.…”

Background The British Thyroid Association and American Thyroid Association guideline definitions for low-risk differentiated thyroid cancers are susceptible to differing interpretations, resulting in different clinical management in the UK. Objective To explore the national effect of these guidelines on the management of low-risk differentiated thyroid cancers. Methods Anonymised questionnaires were sent to multidisciplinary teams performing thyroidectomies in the UK. Risk factors that multidisciplinary teams considered important when managing low-risk differentiated thyroid cancers were established. Results Most surgeons (71 out of 75; 94.7 per cent) confirmed they were core multidisciplinary team members. More than 80 per cent of respondents performed at least 30 hemi- and/or total thyroidectomies per annum. A majority of multidisciplinary teams (50 out of 75; 66.7 per cent) followed British Thyroid Association guidelines. Risk factors considered important when managing low-risk differentiated thyroid cancers included: type of tumour histology findings (87.8 per cent), tumour size of greater than 4 cm (86.5 per cent), tumour stage T3b (85.1 per cent) and central neck node involvement (85.1 per cent). Extent of thyroid surgery (e.g. hemi- or total thyroidectomy) was highly variable for low-risk differentiated thyroid cancers. Conclusion Management of low-risk differentiated thyroid cancers is highly variable, leading to a heterogeneous patient experience.
