A series of 92 thyroid cancer patients treated in collaboration between the Nuclear Medicine and the Oncological Radiotherapy Departments of the Turin Mauriziano Hospital is reported. The age, sex, histotype and stage of the various groups of patients subdivided by therapeutic indications were analysed. In 17 patients, treatment was carried out for pain killing purposes on particularly painful secondary bone localisations with good results symptomatologically and from the point of view of functional recovery. In 21 patients with unfavourable histology who did not take up radioiodine, external radiation treatment was carried out for palliative reasons with, in some case, a lasting effect. In the other 44 patients although generally speaking, at advanced stages of the disease and often in the presence of invasive and anaplastic secondary manifestations, total survival with the two treatments combined was about 55% (24 cases) of whom 75% (18 cases) are alive 5 years later.
