“…In this study, the degree of prognostic risk was based on the commonly used, worldwide, AMES system [2][3][4]. The results of the questionnaire survey conducted in Japan have already been reported elsewhere [5,6]. This study was designed to assess discrepancies in therapeutic policies for well-differentiated thyroid cancer between Japan and other countries.…”

Abstract. Although surgery has been the mainstay of treatment for patients with well-differentiated thyroid cancer, the extents of thyroid resection and lymph node dissection adopted in Japan differ from those in other countries. Furthermore, regarding the indications for postoperative radiation therapy and hormonal therapy, and treatment modalities for cancer recurrence, there are marked discrepancies between Japan and other countries. A questionnaire survey was thus conducted among domestic and overseas thyroid surgeons to ascertain the actual treatment policy for well-differentiated thyroid cancer in Japan and various foreign countries. For small papillary carcinomas of 2.0 cm or less (T1), thyroid resection was more extensive in foreign countries than in Japan, although the extent of lymph node dissection was limited in the former. For large papillary carcinomas exceeding 3.0 cm (T2), on the other hand, total thyroidectomy was the treatment of first choice for all overseas respondents, but of only 20% in Japan, despite lymph node dissection being more extensive in Japan than in other countries. Overseas surgeons were much more likely to favor postoperative TSH suppression therapy and high-dose 131 I therapy. For recurrence following surgery for papillary thyroid cancer, both domestic and overseas respondents indicated surgical resection to be the most common treatment option, and favored high-dose 131 I therapy as well. In Japan, however, high-dose 131 I therapy is available only in a few institutions. Such limited indications for highdose 131 I therapy in Japan may reflect a discrepancy in the frequency of total thyroidectomy, a prerequisite for postoperative high-dose 131 I therapy, between Japan and other countries. This is the first questionnaire study conducted in both Japan and other countries in relation to treatment modalities for thyroid cancer. The results reveal that there is a clear disparity in treatment policies between Japan and foreign countries.

“…However, no randomized prospective studies on patients treated with a total thyroidectomy with radioactive iodine ablation or a lobectomy-only have been published. This book may predict a turning point in the history of medicine for thyroid carcinoma treatment, from a total thyroidectomy with RAI ablation to a lobectomy-only for node-negative low-risk thyroid tumors [5,6].…”

Abstract. Objectives: The optimal extent of surgery and postoperative management of patients with well differentiated thyroid carcinoma (WDTC) vary among countries and institutions. We assessed the practical management of WDTC in Korea by questionnaire and compared these results with those obtained in similar surveys of members of the Japanese Society of Thyroid Surgery (JSTS) and the International Association of Endocrine Surgeons (IAES). Materials and Methods: Questionnaires were sent by mail or e-mail to 266 members of the Korean Association of Endocrine Surgeons (KAES). Ninety members (33.8%) completed the questionnaire; their responses were compared with those of the JSTS and IAES surveys. Results: Total thyroidectomy was more prevalent in the KAES and IAES than in the JSTS, irrespective of tumor size in the low-risk group. Patients with papillary microcarcinoma were more likely to undergo aggressive central compartment node dissection in the KAES than in the IAES or JSTS. Thyroid stimulating hormone suppression therapy was administered to a higher proportion of patients and for longer times in the KAES and IAES than in the JSTS. Postoperative radioactive iodine treatment was more prevalent in the KAES than in the JSTS. There were no differences between the KAES and the JSTS in the treatment of patients with locally advanced thyroid carcinoma. External irradiation and radioactive iodine treatment for recurrent papillary thyroid carcinoma were favored more by the KAES than the IAES and JSTS. Conclusions: The actual practices of members of the KAES were almost similar to those of the IAES, but differed from those in Japan in some aspects. In general, however, members of the KAES favored more aggressive treatment of WDTC than did physicians in other countries.
