[Hormone dependence in functional thyroid cancers, survival after total thyroidectomy combined with radioactive iodine and thyroid extract therapy]. / Hormonodependenica en los cánceres tiroideos fwctionales. Supervivencia con tiroidectomía total asociada a terapéutica con iodo radiactivo y extractos tiroideos

The authors reviewed current criteria on hormone-dependence in functional thyroid cancers, presenting data of compared disease evolution based on the casuistics of thyroid carcinomas from the files of the Fundación Jiménez Díaz, with 5 and 10 year follow-up studies in some of the cases. They found a higher number of survivors among the patients with papilliferous carcinoma in both 5 and 10 year follow-up groups whom, aside total surgical removal of the gland and the administration of thyroid extracts, those who had thyroid residues left were given 100 mc of 131I. Among the patients with follicular adenocarcinoma, under the same comparative conditions, differences were not very clear in the 5 year follow-up group, while the 10 year follow-up group showed marked differences. The authors conclude that an adequate combination of the three therapeutic procedures may allow a higher survival rate.
