Fate of the non-operated, non-toxic goitre in a defined poplulation

Background: There is lack of consensus in Europe regarding the management of patients with benign goitre. This study evaluated the long-term results of recommending no surgery for clinically and cytologically benign goitre. Methods: Some 261 patients (median age 56 years) referred for surgical evaluation for goitre were followed prospectively for a median of 130 months. All hospital and primary care charts were reviewed and living patients interviewed by telephone. Results: During follow-up, 36.4 percent of patients were re-referred for a new surgical evaluation, mainly because of growth of the goitre and/or worsening of local symptoms. Fifty-seven (21.8 per cent) of the patients had surgery, and 13 developed thyrotoxicosis. Five patients (1.9 per cent) were diagnosed with thyroid carcinoma, three of whom (all elderly women) died from the disease. Some 95.0 per cent of patients were satisfied with the expectant policy, but 13.1 per cent had been worried about thyroid cancer despite the reassurance of a benign diagnosis. Conclusion: Patients with benign goitre can be treated conservatively with good results. However, there is a small risk that aggressive carcinoma will develop and about a quarter of patients may need surgery within 10 years of the decision to wait and see.
