PURPOSE: In the treatment of differentiated thyroid carcinomas the indication for adjuvant radiotherapy is discussed contradictory. The following study analyzes the long-term survival rates of patients with follicular and papillar thyroid carcinomas after percutaneous radiotherapy. PATIENTS AND METHOD: Records of 178 patients with differentiated thyroid carcinomas (132 female, median age 46 years; 46 male, median age 47 years) were evaluated. Following thyroid-resection and radioiodine therapy external beam irradiation was performed with a telecobalt device and high energy electrons (mean reference dose 54.7 Gy). Hundred and twenty patients (67.4%) had a histologically confirmed papillary carcinoma, 58 (32.6%) patients had follicular carcinoma. In the group with papillary carcinoma 57 patients (47.5%) were classified as stage I, 11 patients (9.2%) as stage II, 48 patients (40.0%) as stage III, 4 patients (3.3%) as stage IV, respectively, in the group with follicular carcinoma 21 patients (36.2%) were classified as stage I, 4 patients (6.9%) as stage II, 28 patients (48.3%) as stage III and 5 patients (8.6%) as stage IV. Survival, recurrence rate and prognostic factors were analyzed.
