T1-201 and I-131 scintigraphy were performed to visualize malignant lesions postoperatively in 26 patients with well-differentiated thyroid cancer. Anyone of uptake index and retention index was higher in malignant lesions than that in benign lesions. T1-201 scintigraphy showed uptake ininflammatory tissues. T1-201 concentration was observed in fourteen patients and six of them had malignant lesions, while I-131 concentration was observed in six patients and all had malignant lesions. In sensitivity, combination of T1-201 and I-131 scintigraphy is higher than I-131 or T1-201 scintigraphy only. In postoperative patients with well-differentiated thyroid cancer, it may be useful that T1-201 scintigraphy will be performed simultaneously with I-131 scintigraphy for detecting recurrence.

Background/Objectives: To analyze the clinical characteristics of differentiated thyroid cancer (DTC) in children and adolescents. Materials & Methods: Medical records of 31 DTC cases that were diagnosed and treated at Korea Cancer Center Hospital between 2002 and 2018 were retrospectively reviewed. Results: Most cases were papillary carcinoma (n=26), with female predominance (n=25). Median age was 16.4 years (range, 11.9-18.6 years). Extrathyroidal extension was present in 24 cases. Twenty cases had tumor involvement at cervical lymph nodes and three had lung metastasis. Twenty-two patients received radioactive iodide treatment with a median cumulative dose of 300 mCi (range, 100-920 mCi). During a median follow-up of 68.2 months (range, 2.3-191.4 months), serum thyroglobulin level was elevated in 15 patients. Among them, two cases had remnant thyroid tissue, 4 had recurrence at cervical lymph nodes, and the remaining 9 did not have any detectable lesion. All were alive, and 5-year event-free survival (EFS) was 45.2±10.1%. Age £15 years, tumor size, lymph node status (N1b), and distant metastasis had negative effects on EFS. On multivariate analysis, age and tumor size had prognostic significance. Conclusion: For DTC of children and adolescents (£18 years old), age ≤15 years and tumor size were prognostic factor. Therefore, patients in this age group need meticulous follow-up. Further studies are necessary to answer the potential influence of age on the incidence and behavior of DTC.

Background: Thyroid tumors are generally regarded as rare malignancies. Nowadays, however, their global incidence is growing continuously partially due to western life style and utilization of more sensitive methods of early detection. It is approximately three times more prevalent in females than in males. Most cases of thyroid cancer are asymptomatic nodules or just have local cervical symptoms or adenopathy in early stages. Materials and Methods: The Global Burden of Diseases report 2010 study (released 3/2013) profited from 100 collaborators worldwide and used a vast network of data on health outcomes, vital registries, and population surveys. It shared many of the Global Burden of Diseases 1990 principal databases such as all available data on injuries, diseases, risk factors, as well as comparable metrics, and used different scientific approved methods to estimate important health status data like: death rate, life expectancy, healthy adjusted life expectancy, disability-adjusted life years (DALY), years of living lost due to premature death and years of life with disabilities. Results: DALY as thyroid cancer burden per 100,000 Iranian populations had increased by about 14% during 1990 to 2010 in all ages; from 6.1 (95% UI 4.2-9.74) years in 1990 to 6.95 (95% UI 5.06-9.18) years in 2010 in both sex. The 2010 peak age-group was estimated at 45-49 years in males and 40-45 years in females.

Advanced or recurrent thyroid cancer, and metastatic paratracheal lymph nodes may directly invade the trachea and lead to tracheal stenosis. In these cases the stenosis is not circumferential and it would be possible to reconstruct the trachea after partial resection of the stenotic trachea. We experienced five cases of tracheal reconstruction after partial resection of the tracheal wall in four Patients of advanced thyroid cancer, and in one Patient of malignant paratracheal lymphadenopathy.

Thyroid cancer is one of the most common cancers in Korea, and thyroidectomy is the first-line treatment. Hypoparathyroidism is a common complication of thyroidectomy and can cause symptoms such as numbness, spasm, and anxiety, but these issues have seldom been reported in the Korean medical literature. The present case was a 53-year-old thyroid cancer patient who complained of numbness caused by hypoparathyroidism, general weakness, fatigue, and postoperative pain after total thyroidectomy. The patient was treated with Korean medicine treatment, including herbal medicine, acupuncture, cupping, and moxibustion, and her changes in clinical symptoms were measured with a numeric rating scale (NRS), the Karnofsky performance status scale (KPS), and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30). After treatment, her clinical symptoms were improved, leading to an improvement in her quality of life. Therefore, Korean medicine may be effective in the treatment of thyroid cancer patients who experience numbness caused by hypoparathyroidism, general weakness and fatigue after total thyroidectomy.

Supracricoid partial laryngectomy (SCPL) has been performed in selected patients with transglottic carcinoma of larynx who are not amenable to classically conservative Partial laryngectomy. We have applied this procedure for the complete removal of carcinoma and the satisfactory recovery of function in 74 supraglottic laryngeal cancer Patient with thyroid cartilage invasion. The 65-year-old man with supraglottic squamous carcinoma with thyroid cartilage invasion (74 stage) was treated by SCPL with bilateral lateral neck dissection. The part of larynx and whole thyroid cartilage with tumor invasion was completely removed with covering thyrohyoid muscle and fascia. External perichondrium of the thyroid cartilage containing carcinoma was not exposed from the overlying muscle and fascia on postoperative pathological examination. We confirmed the invasion of thyroid cartilage histopathologically. Tumor was confined in the specimen and the safety margin was proved in all direction. Postoperative course and functional results were uneventful. SCPL can be applied in selected cases of locally advanced 74 laryngeal cancer.

Background: The diagnostic approach to thyroid nodules involves ultrasound-guided fine needle aspiration biopsy (US-FNAB). We especially aimed to evaluate the contribution and the place of US-FNAB in preoperative evaluation of the malignant cases and draw attention to discordant cases diagnosed with papillary thyroid microcarcinoma (PTMC). Materials and Methods: A total of 276 cases were retrospectively reviewed who were subsequently diagnosed with a malignancy and who underwent US-FNAB. Results: Some 45 were found to have previously undergone the US-FNAB procedure. Of the patients in whom the surgical specimen was diagnosed with a malignancy, 21 (46.7%) were diagnosed as malignant or suspicious for malignancy, and 24 (53.3%) were concluded as benign or insufficient for diagnosis. Patients with the diagnosis of PTMC outnumbering the others was a striking finding (11 cases, 24%). Conclusions: We suggest performing repeat aspiration biopsy considering sampling errors in cases where inconsistency exists between clinical findings and cytological results in thyroid nodules smaller than 10 mm in diameter and with suspicious findings on ultrasonography.

Robotic thyroidectomy has been developed to minimize neck scarring, and several authors have described its feasibility and safety, and have reported surgical outcomes comparable with conventional open thyroidectomy. The da Vinci surgical system robot provides a three-dimensional $10-12{\times}$magnified view of the surgical area. It also provides hand-tremor filtration, fine motion scaling, and precise and multi-articulated hand-like motions. Recently, robotic technology has also been applied to lateral compartment neck dissection in thyroid cancer. We have developed a new novel selective neck dissection procedure by a gasless unilateral axillo-breast (GUAB) approach with a da Vinci Surgical System for well-differentiated thyroid carcinoma to avoid a long visible neck scar. Based on our early experience, robotic selective neck dissection by GUAB approach is a safe, feasible and cosmetically excellent procedure. It can be an alternative to conventional open surgery in the highly selected patients with well-differentiated thyroid carcinoma. The oncologic safety of robotic selective neck dissection should be verified with long-term follow-up data.
