“…Lymph node involvement should be always suspected since, histologically, micrometastases may be found in about 50% of cases without clinical lymph node evidence [22]. The reported occurrence of distant metastases in childhood, varying between 1.5% and 26%, has been interpreted as the expression of a higher aggressiveness of thyroid tumours at this age [22,31]. In our series, lung involvement was found in two patients (4.2%), without significant difference versus the older age groups (3.3%), being much lower than the 25% reported by Mizukami et al [18], and the 42% reported by Schlumberger et al [22].…”

“…Our experience confirms the high frequency of locoregional lymph adenopathy in childhood compared to adults (54% vs 33%), but with a slightly lower overall prevalence than that reported by others [2,10,22,31]. In particular, lymph nodes were the only clinical sign in 14.5% of patients (Table 1).…”

“…Therapeutic modality in carcinomas of thyreocyte origin in children is total thyroidectomy combined with unilateral or bilateral functional neck dissection and radioiodine therapy [2][3][4]. However, morbidity of total thyroidectomy in children is relatively high [1][2][3].…”

“…Until the 1930s, few cases of such malignomas are presented in the literature [2]. Between the 1930s and the 1950s, an increase in tumor incidence was observed, based on neck irradiation in patients with adenoid or thymus hyperplasia [3]. In the 1960s, after stopping this form of therapy, incidence of thyroid carcinoma decreased, reaching the present incidence of 3 to 5 cases per 100,000 children per year [4].…”

“…Since thyroid cancer has been such a conspicuous result of irradiation in infancy or childhood (Winship and Rosvoll, 1961;Saenger et al, 1960;Hempelmann et al, 1967), it is unfortunate that there is no published information on its association with antenatal radiography. An idea of the upper limit to the risk from antenatal radiography may perhaps be derived by assuming that all cases of thyroid cancer diagnosed before 20 years of age are due to antenatal radiography.…”

The relative sensitivity of different tissues to tumour induction by radiation: The human evidence

Introduction 83The most straightforward way to assess the 87 relative sensitivity of different tissues to the induction of tumours by radiation would be to 89 compare the induced tumour rates when all the 89 tissues received the same dose at the same time. 94 No assumption need then be made about the form of the close-response relation except that it 94 is the same in all tissues. The only close approach to this ideal situation in man is the exposure of the 95 foetus in antenatal radiography. In all the other 56 RADIOSENSITIVITY AND SPATIAL DISTRIBUTION OF DOSE 57 Circumstances in which large fractions of the body, and therefore many different organs, have been irradiated, therapeutically, accidentally, occupationally, or in war, the dose received by different organs has varied considerably, even when the organs have been "directly" irradiated. For example, it has been suggested that the dose in the stomach in an ankylosing spondylitic given X-ray therapy was about one-tenth of the dose in the overlying spinal marrow (Dolphin and Eve, 1968). An allowance for the difference in dose has to be made if the observed tumour incidences in the different organs are to provide information about the relative sensitivity of these organs to tumour induction.The ICRP assumes a linear relation between dose and biological effect. This is certainly the simplest function and will be used in what follows. The effect of choosing a different form of dose-response is considered later.A linear relation between radiation dose and tumour induction has implications for the mechanism of carcinogenesis by radiation. It cannot be expected to hold when the dose is high enough to produce gross tissue damage. When a high proportion of tissue cells is killed, tumour yield may well be reduced and when healing is imperfect, or fibrosis is marked, tumour yield may be increased. Extrapolation from such situations is primafacie a highly unreliable guide to what might be expected at dose limit or emergency levels of exposure. Therefore, information about tumour induction following localized therapeutic irradiation for cancer has not been used in formulating our conclusions. Also excluded is all information about tumour induction by radioactive materials that are selectively concentrated in particular organs--such as the bone-seekers and the isotopes of iodine and phosphorus. The problems of estimating the ratio of dose in the concentrating tissue and in the adjacent tissues are formidable (cf. ICRP Publication 11, A Review of the Radiosensitivity of the Tissues in Bone, 1968).Particularly useful information is available from three categories of human subjects--British patients with ankylosing spondylitis irradiated as adults, Americans irradiated in infancy or childhood for a supposedly enlarged thymus or for a variety of childhood complaints, and Japanese of all ages when exposed to an atom bomb explosion. In each category there was a range of exposure levels, and an approximate dose-response can be ascertained for two kinds of malignant diseas...
