An audit of management of differentiated thyroid cancer in specialist and non-specialist clinic settings.

Abstract

Thyroid cancer is the most common endocrine malignancy but is none the less rare. Some aspects of its management remain controversial. Previous audits of patient management in the United Kingdom have revealed deficiencies, especially in communication between specialists. We have audited patient management in a large university-associated teaching hospital, assessing points of good practice identified from published guidelines and reviews, and have compared findings in groups of patients managed jointly by specialists with an interest in thyroid cancer (including surgeon, endocrinologist and oncologist) with a group managed by other clinicians outside that setting. Retrospective case-note review of 205 patients with differentiated (papillary or follicular) cancer including group A (n = 134; managed in a specialist multi-disciplinary clinic setting) and group B (n = 71; managed in other clinic settings). Points of good practice investigated were adequacy of surgery, surgical complications, prescription and adequacy of T4 treatment, adequacy of monitoring by measurement of serum thyroglobulin and action taken and appropriate administration of ablative radioiodine. Deficiencies in management of the cohort as a whole were identified, including inadequate surgery and inadequate TSH suppression in approximately one-fifth of the cases. Monitoring with thyroglobulin measurements and action when serum thyroglobulin was high were also inadequate in some cases and ablative radioiodine was not given, despite being indicated in 11.7% of the cohort. Inadequate surgery and failure to administer radioiodine were less common in those managed in a specialist clinic setting than in those managed in other clinic settings. The findings highlight the need for locally agreed protocols in managing relatively rare endocrine disorders such as thyroid cancer and argue in favour of centralization of expertise and patient management in multi-disciplinary specialist clinic settings.
