| Abstract: | This is a review of one surgeon''s personal experience with 85 patients with thyroid cancer treated over a 20-year period. The data confirm that for papillary thyroid tumours, with rare exceptions, the prognosis is excellent. Anaplastic lesions, however, are consistently lethal. Follicular carcinoma and medullary carcinoma fall between these extremes. A simple clinical classification is offered as a guide to operative management and a reliable index of prognosis. Patients with clinically apparent, "manifest cancer" have serious, life-threatening disease; many such patients die of their disease. Patients with "neck lumps not yet diagnosed" usually have papillary carcinoma; their prognosis is excellent. Patients whose thyroid tumours fall into the category of "malignant nodule" or "pathologist''s cancer" are particularly fortunate: in this series no such patient has died. The importance of age in relation to thyroid cancer is also confirmed: non of the patients first treated before the age of 40 years has died of cancer. For young patients with favourable disease the author recommends conservative surgical treatment, which avoids cosmetic deformity or functional disability, to be followed by administration of levothyroxine to suppress production of thyroid=stimulating hormone. For patients with "unfavourable" thyroid cancer valuable palliation can often be achieved by a combination of surgery and irradiation. Survival rates for the total series are 76% at 5 years and 60% at 10 years. |
