SummarySPECT/CT detects radioiodine-positive cervical lymph node metastases (LNMs) of differentiated thyroid carcinoma (DTC) at the time of postsurgical radioablation (RA). Preliminary evidence indicates that the majority of LNMs are successfully treated by RA. The aim of this study was to confirm this evidence in a bicentric setting and to evaluate whether size is a predictor for successful elimination. Patients and methods: Since 01/2007 and 05/2008, respectively, SPECT/spiral-CT is performed routinely in all patients with DTC at RA in two University Clinics. The outcome of iodine-positive LNMs identified by SPECT/CT until 12/2012 was analyzed by follow-up diagnostic 131I scans and serum thyreoglobulin (Tg) values. LNM volume and short-axis diameter were evaluated as prognostic factors by a receiver-operating characteristic (ROC) analysis. Results: 79 patients with 97 iodine-positive LNMs were included. Surgery was carried out in 8 patients with 13 LNMs due to the presence of additional iodine-negative lesions. Of the remaining 84 LNMs, 74 (88%) were successfully treated as demonstrated by radioiodine scans at follow-up. 10 LNMs persisted. 67/70 LNMs smaller than 0.9 ml were treated successfully, whereas this was the case of only 6/14 exceeding this threshold. Using this cut-off level to predict treatment success, sensitivity, specificity, positive and negative predictive value were 92%, 73%, 96%, and 57%. Results for short-axis diameter (cut-off level < 1cm) were 90%, 69%, 94% and 56%. Conclusion: RA is effective in the treatment of the majority of 131I-positive LNMs identified in SPECT/CT images. In this study, 88% of iodine-positive LNM in DTC were successfully treated by radioiodine given at RA. Both LNM volume and diameter are reliable predictors of treatment success.

From 1977 through 1995, 1,013 thyroid carcinoma patients received treatment and were followed up at Chang Gung Medical Center in Taiwan. To evaluate the prognostic variables of papillary and follicular thyroid carcinomas with limited lymph node metastases, a retrospective review of these patients was performed. Of these patients, 910 had papillary or follicular thyroid carcinoma, and 119 patients were categorized as clinical stage 2 with limited neck lymph node metastases only at the time of diagnosis. The patients were categorized into two groups as no recurrence and local recurrence or distant metastasis at the end of 1997. After the operations, radioactive iodide (131I) treatments were performed in 114 patients and external radiotherapy for neck region or distant metastases in 18 patients. The median follow-up period of these patients was 5.4 years. Clinical variables were coded in our computer for statistical analysis. After the treatments, 93 patients remained disease-free; 10 were in stage 2; 5 in stage 3; and 11 aggravated to stage 4. Of the clinical variables, age, post-operative first 1311 uptake scans, and 1-month post-operative thyroglobulin levels revealed statistically significant differences between the group which improved and the group which did not. During the follow-up period, five patients died; three patients died of thyroid cancer and two died of intercurrent diseases. Patients with papillary thyroid carcinoma revealed a higher percentage of lymph node metastases. Although limited lymph node metastases did not influence survival rate, patients with poor prognostic factors need more aggressive treatment to avoid progression of the cancer.

Objectives. We compared the ultrasonography and pathology features of papillary thyroid carcinoma (PTC) in pediatric and adolescents with Hashimoto’s thyroiditis (HT) with those of non-HT patients.Materials and Methods. Eleven patients who were surgically confirmed to have pediatric or adolescent PTC from 2006 to 2014 were included in this study. We retrospectively analyzed the preoperative ultrasonography and pathology features of PTC arising in HT and non-HT patients.Results. On ultrasonography, thyroid gland was lobulated and enlarged, with many scattered microcalcifications in four of five HT patients. Four of six non-HT patients had suspicious masses with calcifications. The diffuse sclerosing variant of PTC (DSVPTC) was found in three of five HT patients, but none in non-HT patients. Macroscopic or microscopic extrathyroidal extension was evident in all of the HT patients and four of the non-HT patients. Neck lymph node metastases were in all HT patients and five of non-HT patients.Conclusions. Three of five PTCs in pediatric and adolescent HT patients were DSVPTC, whereas all PTCs of the non-HT patients were classic type. On ultrasonography, thyroid gland was diffusely enlarged with scattered microcalcifications in four of five HT patients. All five HT cases had aggressive disease, including extrathyroidal extension and cervical lymph node metastases.
