title: [Loco-regional persistence and recurrences of operated differentiated thyroid cancers. 22 cases on 589 treated patients from 1964 to 1990, follow-up from 5 to 31 years].
abstract: OBJECTIVE
  Evaluation of frequency and outcome of loco-regional persistance and recurrences of differentiated thyroid carcinomas after surgery.
  
  
  METHODS
  from 1964 to December 1990, we operated and followed up more than 5 years (from 5 to 31 years): 589 thyroid cancers (309 papillary, 262 follicullar et 18 Hürthle cells); 145 patients were lost to follow-up (24%), 33% of them were microcarcinomas. Surgery consisted ultimately in 411 total thyroidectomies, 51 sub-total thyroidectomies, 113 lobectomies with isthmusectomies, 9 isthmusectomies or tumorectomies and 4 tracheotomies. Neck dissection was not routinely performed but rather selectively (n = 137). All Patients were put under suppressive hormone therapy. After total thyroidectomy, ablative 131 iodine was almost routinely done. All patients have been controlled by clinical examination, radio-iodine scanning and, since 1983, by sequential thyroglobulin assays. We have analysed the course of patients according to L. J. Degroot's staging (Stage I: Patient with intrathyroidal disease. Stage II: Patient with cervical node involvement. Stage III: Patient with extra-thyroidal neck invasive disease. Stage IV: Distant metastasis).
  
  
  RESULTS
  Stage I, n = 383, Stage II, n = 96. Total = 479. Local recurrences in the bed of total thyroidectomy were exceptional: n = 2/323 (0.6%). Recurrences in the thyroid remnant after non total thyroidectomy were rare: n = 3/156 (2%). Cervical nodal recurrences were also rare: n = 7/479 (1.5%). Stage III (n = 73): 34/306 papillary, 9/78, well differentiated follicular, 25/175 poorly differentiated follicular. 2/9 follicular of other type and 3/18 hurtle cell. In 67 patients, the loco-regional sterilization was achieved, 5 of which were reoperated for nodal cervical metastasis. 6 patients died from continuing loco-regional disease and 10 presented distant metastases. 4 of which died from. Among opered patients are still alive (52/73 = 71,2%) no loco-regional recurrence persisted.
  
  
  CONCLUSIONS
  The true problem is not recurrence but the persistance after surgery in stage III patients, despite the application of 1131. The determining factor of the persistance and recurrence is the initial stage of the carninomatous disease at the time of treatment.
