[Thyroid cancer. A multidimensional analysis of prognostic factors]

189 patients treated from 1970 to 1979 were reviewed. The isolated prognostic value on 10-year survival of age, histology, sex, tumor size and metastases was confirmed. Using Cox model, histology, age and sex appeared to be sufficient to settle a prognosis, while histology was the most determining prognostic factor. From these 3 variables, a prognosis score was proposed. Patients were distributed among 3 prognostic groups, the 10 years survivals of which were respectively 93%, 57% and 28% (p less than 0,001).
