VII. Summary and Conclusions. I. INCIDENCE. It is not easy to estimate precisely the incidence of malignant disease of the thyroid, since there are hardly any vital statistics available which relate to the matter. We have to rely largely, therefore, on the figures provided by the more important thyroid clinics which enable us to deduce the incidence of malignant goitre compared with that of benign and thyrotoxic goitres. The ratio varies rather widely in different clinics, viz., 7.4 per cent.' (Kocher) down to I * 2 per cent.2 (Coller) or less, and it appears that the larger ratios are found more particularly in areas of high endemicity for thyroid disease. So far as mortality statistics go, we are fdrtunate in having accurate figures for England and Wales which show for males a mean annual standardized death rate at all ages of 2-4 for the quinquennium I93I-5, and of 2-3 for the period I936-9, whereas for women the corresponding figures are 5 3 for both periods.3 These mortality rates, when compared with those of the first three decades of the century, show a decided and steady increase in both sexes. In my own series* of 7,039 thyroidectomies there have been I27 cases of malignant goitre verified by histological examination, the percentage I * 8 being roughly comparable with that at several other large thyroid clinics in areas not highly endemic for goitre. It has been pointed out by Pemberton4 that there is a fallacy in all such figures, since many patients with innocent goitres do not bother to attend the clinic, while all those with malignant goitres sooner or later present themselves for treatment, and that therefore the actual ratio of malignant to innocent goitre is always smaller than such figures as I have given would imply.
