Sternal metastasis of poorly differentiated thyroid carcinoma (PDTC) is rare, and only a few cases have been reported in the literature. Here, we report a case of sternal metastasis of PDTC in an 83-year-old woman, 2 years after right hemithyroidectomy, treated with sternal resection and reconstruction.

Radiofrequency ablation (RFA) has been a representative, non-surgical treatment for benign thyroid nodules that cause cosmetic problems or compression symptoms. The procedure of RFA should be performed effectively and safely. This review discusses the patient selection, pre-procedure evaluation and planning, principles, devices, techniques, and complications with reference to the guidelines and research on thyroid RFA. In particular, this review will devote to introduce RFA techniques and to provide practical help in the implementation of this procedure.

본 논문에서는 국내 갑상선암의 연구 동향을 파악하기 위해 텍스트 중심의 접근법을 제안한다. 국내 갑상선암은 2000년대에 들어서며 발생이 급증하여 과잉진단의 논란을 불러일으켰으나, 다양한 분야의 자정 노력으로 수술 환자수가 크게 줄었다. 본 연구에서는 텍스트 마이닝 기술을 사용하여 디비피아에 등록되어 있는 갑상선암 관련 논문의 키워드와 초록을 수집하여 분석하였다. 1980년대는 대부분의 사례보고가 있었고 1990년대에 들어서면서 검진을 통한 조기 진단의 내용이 자주 나타났다. 2000년대에는 여러 장비들을 활용한 검사방법과 미세한 암의 발견에 대한 논의가 증가하였음을 확인 할 수 있었다. 2010년대에 들어서는 환자의 삶의 질에 대한 연구가 많이 이루어졌다. 지난 수십 년 동안 갑상선 암 연구 주제에 대해 뚜렷한 변화가 나타났으며, 향후 연구의 기초자료로 활용될 수 있으리라 기대된다.

Metastases to regional cervical lymph nodes occur frequently in patients with thyroid cancer. The appropriate management of regional lymph node is important to achieve good disease control and to classify risk stratification for adjuvant radioactive iodine. However, there are some occasions that neck dissection is difficult and embarrassing in thyroid cancer. Especially, extensive or unusual nodal metastases bring challenges and makes neck dissection more difficult. Carotid artery management is one of the most difficult procedure in neck dissection. The management of patients who have persistent or recurrent cervical metastasis involving the carotid artery has been controversial and treatment dilemma to the surgeon. Metastasis of well differentiated thyroid cancer to the retropharyngeal lymph nodes is rare but occasionally encountered. The complete surgical excision is usually recommended for retropharyngeal lymph node metastasis of well differentiated thyroid cancer. An extensive mediastinal dissection in advanced differentiated thyroid carcinoma is occasionally required. This paper will review recent reports of management of advanced nodal metastasis of thyroid cancer and share the author's personal experience.

Evaluating the patient's voice before thyroidectomy is useful for the purpose of identifying patients with vocal cord paralysis without symptoms, identifying other patient's voice abnormalities, and whether it is related to voice disorders that may occur after surgery. Also voice evaluation after thyroid surgery is helpful in diagnosis, treatment, and rehabilitation and follow-up of voice disorders that occur without clear nerve damage after thyroidectomy. And it is helpful for rapid recovery through active early rehabilitation treatment for patients who complain of speech impairment without paralysis. In particular, neck exercise can improve the adhesion of the surgical site and increase the range of motion of the neck as well as improve subjective neck discomfort. In addition, hearing, voice and breathing functions should be improved, and voice hygiene education and counseling should be provided. Vocal cord injection is the first treatment option for unilateral vocal cord palsy. By establishing a protocol for voice disorders before and after thyroid surgery and providing appropriate treatment, the quality of life of patients can be improved.

편측 성대마비에 대해서 Teflon 삽입술, 갑상연골성형술, 피열연골내전술 등 여러 술식이 사용되고 있다. 1993년 3월부터 1993년 10월까지 서올대학교병원 이비인후과에서는 여러 가지 원인으로 발생한 8례의 편측 성대마비에 대해서 피열연골 성형술을 시행하여 다음과 같은 결과를 얻었다. 원인으로는 특발성이 3례, 갑상선 수술에 후발한 것이 2례, 경부종괴절제수술에 후발한 것이 2례, 흉부수술에 후발한 것이 1례, 디프테리아가 1례였고, 좌측 성대마비가 5례, 우측 성대마비가 3례였다.(중략)

Post-thyroidectomy syndrome refers to various voice changes experienced after the thyroid surgery. Among them, surgery or injection therapy has been prioritized over voice therapy for the bilateral vocal cord paralysis. However, if it is possible to determine whether voice therapy can be applied first, a faster treatment recovery will be possible. In this study, voice therapy was performed on a 59-year-old female patient with bilateral vocal cord paralysis after total thyroidectomy. This study is to presents the criteria for applying the voice therapy first for bilateral vocal folds paralysis and to share successful voice therapy sessions.

Purpose: To evaluate diagnostic sensitivity of nuclear imaging in the detection of residual thyroid tissue and metastatic lesion, we have compared neck scintigrams with Tc-99m pertechnetate (Tc-99m scan) and high dose I-131 iodide (I-131 scan) in patients with differentiated thyroid cancer. Subjects and Methods: One hundred thirty-five thyroidectomized patients for differentiated thyroid cancer were enrolled in this study. Twenty-three had a previous history of radioiodine therapy. Planar and pin-hole images of anterior neck with Tc-99m were acquired at 20 minutes after injection, followed by I-131 scan three days after high-dose radioiodine therapy within 7 days interval. Patients were asked to discontinue thyroid hormone replacement more than 4 weeks. Results: All subjects were in hypothyroid state. Seventy out of 135 patients (51.9%) showed concordant findings between Tc-99m and I-131 scans. I-131 scan showed higher number of uptake foci in all of 65 patients showing discordant finding. Tc-99m scan showed no thyroid bed uptake in 34 patients, whereas 23 of them (67.6%) showed bed uptake in I-131 scan. Tc-99m scan did not show any uptake in thyroid bed in 11 of 112 patients without previous history of radioiodine therapy, but 9 of them showed bed uptake in I-131 scan. Tc-99m scan showed no bed uptake in all of the 23 patients with previous history of radioiodine therapy, in contrast 14 of them (60.9%) showed bed uptake in I-131 scan. Conclusion: These results suggest that Tc-99m scan has poor detectability for residual thyroid tissue or metastatic lesion in thyroidectomized differentiated thyroid cancer patients, compared to high dose I-131 therapy scan. Tc-99m scan could not detect any remnant tissue or metastatic lesion in patients with previous history of radioiodine treatment, especially.
