Abstract Introduction: Worldwide, the increasing incidence of thyroid cancer, along with a parallel increase in obesity and metabolic disorders, suggests that modifications of lifestyle and environmental factors might explain the rise in thyroid cancer incidence (1). Objective: To investigate the association between metabolic syndrome and their elements and their possible association with the risk of thyroid cancer. Materials and Methods: We enrolled 200 patients, who underwent total thyroidectomy for multinodular goiter (Bethesda II-V categories on the basis of fine needle aspiration biopsy cytological examination). We included subjects with differentiated thyroid carcinoma, the ones with poorly differentiated, anaplastic, medullary thyroid carcinomas and secondary tumors were excluded from the analysis. Patients were divided into two groups, according to the post-surgical histological diagnosis: 60 patients diagnosed with papillary or follicular thyroid cancer and 60 diagnosed with benign thyroid disease. The patients had a mean age of 56.9 years old and the majority were females (90%). Relative risk of incident thyroid cancer was assessed by preoperative levels of body mass index (BMI), blood pressure, blood levels of glucose, cholesterol, triglycerides, and the presence of metabolic syndrome (according to the NCEP ATP III definition). The two groups had similar age, gender distribution, smoking habit. Mean BMI was slightly higher in the group with patients with differentiated thyroid cancer and the majority were obese (27.41 ± 5.38 kg/m2versus 26.42 ± 5.18 kg/m2). The patients from the differentiated thyroid cancer group showed a higher percentage of diabetes mellitus and impaired fasting glucose compared to the second group (20% versus 13%), with mean fasting blood sugar levels of 97 ± 2.69 mg/dl in the first group versus 73 ± 3.06 mg/dl in the second group. 30% of the patients from the differentiated thyroid cancer group presented criteria for metabolic syndrome. There was a positive correlation between the presence of hypertension and the diagnosis of differentiated thyroid cancer (p<0.05). Conclusion: Our study showed a potential association between metabolic risk factors and the diagnosis of differentiated thyroid cancer. Besides the improvement of diagnosis, thyroid cancer increasing incidence is probably due to environmental factors and lifestyle modifications. As a future perspective of this study and based on the hypothesis of glucose dependency of many tumor types, another therapeutic strategy can involve diet (low-carbohydrate, high-fat) in order to target metabolism in tumors and alter the Walburg phenothype.

Diagnosis Of Thyroid Cancer

Pulmonary metastases were found in 123 out of 840 patients with thyroid cancer between 1955-1977. 87 patients with pulmonary metastases of differentiated cancer were studied in detail, including an evaluation of prognostically important factors. In 66 of them, the induction of 131I uptake in metastases was attempted, in half of them successfully. Uptake was achieved more frequently in younger subjects, in papillary cancers and in patients with fine pulmonary metastases on chest films. Survival (not corrected for age) was evaluated 10 and 15 years following the diagnosis of thyroid cancer and was found to be 29,1 % and 12,2%, respectively. Significantly higher survival rates were seen in younger patients, in patients with the fine type of pulmonary metastases, in the absence of bone metastases and, particularly, in patients with induced 131I uptake in metastases. Papillary cancers were found to have higher survival rates in males and in young subjects only, in the whole group the survival rates were independent of either microscopic type or sex. It is believed that biologic behaviour of distant (pulmonary) metastases may be influenced by radioiodide therapy.

Retrospective Multicenter Study

Summary:Aim: For the surgical therapy of differentiated thyroid cancer precise guidelines are applied by the German medical societies. In a retrospective multicenter study, we investigated the following issues: Are the current guidelines respected?. Is there a difference concerning the surgical radicalism and the outcome?. Does the perioperative morbidity increase with the higher radicalism of the procedure?. Patients, methods: Data gained from 102 patients from 17 regional referral hospitals who underwent surgery for thyroid cancer and a following radioiodine treatment (mean follow up: 42.7 [24-79] months) were analyzed. At least 71 criterias were analyzed in a SPSS file. Results: 46.1% of carcinomas were incidentally detected during goiter surgery. The thyroid cancer (papillary n = 78; follicular n = 24) occurred in 87% unilateral and in 13% bilateral. Papillary carcinomas <1 cm were detected in 25 cases; in five of these cases (20%) contralateral carcinomas <1 cm were found. There were significant differences concerning the surgical radicalism: a range from hemithyroidectomy to radical thyroidectomy with lateral neck dissection. Analysis of the histopathologic reports revealed that lymph node dissection was not performed according to guidelines in 55% of all patients. The perioperative morbidity was lower in departments with a high case load. The postoperative dysfunction of the recurrent laryngeal nerve (mean: 7.9% total / 4.9% nerves at risk) variated highly, depending on differences in radicalism and hospitals. Up to now these variations in surgical treatment have shown no differences in their outcome and survival rates, when followed by radioiodine therapy. Conclusion: Current surgical regimes did not follow the guidelines in more than 50% of all cases. This low acceptance has to be discussed. The actual discussion about principles of treatment regarding, the socalled papillary microcarcinomas (old term) has to be respected within the current guidelines.

Summary Aim: Tumor scintigraphy with 201-TICI is an established diagnostic method in the follow-up of differentiated thyroid cancer. We investigated the relationship between thyroglobulin (Tg) level and tumor detectability. Subject and methods: We analyzed the scans of 122 patients (66 patients with proven tumor). The patient population was divided into groups with Tg above (N = 33) and below (N = 33) 5 ng/ml under TSH suppression or above (N = 33) and below (N = 33) 50 ng/ml under TSH stimulation. Tumor detectability was compared by ROC-analysis (True-Positive-Fraction test, specificity 90%). Results: There was no significant difference (sensitivity 75% versus 64%; p = 0.55) for patients above and below 5 ng/ml under TSH suppression and a just significant difference (sensitivity 80% versus 58%; p = 0.04) for patients above and below 50 ng/ml under TSH stimulation. In 18 patients from our sample with tumor, Tg under TSH suppression was negative, but 201-TICI-scan was able to detect tumor in 12 patients. Conclusion: Our results demonstrate only a moderate dependence of tumor detectability on Tg level, probably without significant clinical relevance. Even in patients with slight Tg elevation 201-TICI scintigraphy is justified.
