[Advanced age and clinical staging in the prognostic evaluation of differentiated carcinoma of the thyroid gland]. / Età avanzata e stadio clinico nella valutazione prognostica del carcinoma differenziato della tiroide.

ABSTRACT

The prognostic significance of age in differentiated thyroid tumours is assessed via the analysis of 156 cases of differentiated thyroid carcinoma surgically treated in 1967-85. A statistical analysis was performed on a sample of 120 patients under observation since their operation. The results indicate that the negative influence of old age is due more to the higher incidence of advanced tumours among the elderly than to more aggressive behaviour by the tumour.
