[Clinical and instrumental study program of nodular diseases of the thyroid].
Authors have passed from a combined clinical and radioisotopic analysis to an integrated polyinstrumental approach by adding thermography and above all echography. In order to achieve the purpose Authors have confronted in retrospective a "clinico-radioisotopic group" of 103 cases, from 1965 to 1975, and an "integrated polyinstrumental group" of 53 cases, since 1976. Comparing the "clinico-radioisotopic method" with "polyinstrumental approach" the main results could be summarized as follows: the diagnostic specificity improved in benign lesions from 77% to 96%, however in malignant lesions it remained about the same (63%). Considering these results the Authors have subdivided thyroid nodules, mainly based on echography, in two distinct categories with the following orientation: I. Solitary Thyroid Nodule: a) definitely cystic -- demonstrated by echography; b) "cold" -- by conventional scintygraphy; c) "negative" -- by thermography; d) non uptake of tumor seeking radiopharmaceutical. The control, therapy and surveilance of these cases should be limited to needle aspiration of the cystic cavity followed, of course, by citologic examination. This aspirations is both diagnostic and possibly therapeutic. II. Solitary Thyroid Nodule: a) definite solid -- echography; b) "cold" -- convential scintygraphy; c) "positive" --thermography (possibly "negative"); d) non uptake of tumor seeking radiopharmaceutical. Here the therapeutic orientation is clearly surgical.
