Korean Society of Thyroid-Head and Neck Surgery appointed a Task Force to provide guidance on the implementation of a surgical treatment of oral cancer. MEDLINE databases were searched for articles on subjects related to “surgical management of oral cancer” published in English. Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. The quality of evidence was rated with use RoBANS (Risk of Bias Assessment Tool for Nonrandomized Studies) and AMSTAR (A Measurement Tool to Assess the Methodological Quality of Systematic Reviews). Evidence-based recommendations for practice were ranked according to the American College of Physicians grading system. Additional directives are provided as expert opinions and Delphi questionnaire when insufficient evidence existed. The Committee developed 68 evidence-based recommendations in 34 categories intended to assist clinicians and patients and counselors, and health policy-makers. Proper surgical treatment selection for oral cancer, which is directed by patient- and subsite-specific factors, remains the greatest predictor of successful treatment outcomes. These guidelines are intended for use in conjunction with the individual patient's treatment goals.

Thyroid cancer is the most common malignancy in Korea; in 2012, about 44,000 new cases (19.6% of all malignancies) were registered and the estimated age-standardized incidence rate of thyroid cancer was 73.6 per 100,000 (17.3 and 88.6 per 100,000 in men and women, respectively). Despite the steep increase in its incidence, the age-standardized mortality rate of thyroid cancer has remained stable and 10-year relative survival rate is 99.2%. Increased detection using high-resolution ultrasonography may have contributed to the increased incidence of thyroid cancer if not all. However, the effectiveness of thyroid cancer screening using ultrasonography has not been fully evaluated as to whether screening and early diagnosis could decrease the morbidity or mortality of thyroid cancer. A multidisciplinary expert committee for developing a guideline for thyroid cancer screening was organized and established a recommendation for thyroid cancer screening using ultrasonography in Korea based on scientific evidence for the first time. In conclusion, the current evidence is insufficient to assess the balance of benefits and harms of the thyroid cancer screening by ultrasonography and the recommendation is that thyroid ultrasonography is not routinely recommended for healthy subjects.

PURPOSE: The purpose of this study is to determine the status of nodal disease, including the right paraesophageal node, in papillary thyroid carcinoma (PTC). METHODS: A total of 116 patients with PTC underwent total thyroidectomy and prophylactic central node dissection, including right paraesophageal lymph nodes (RPE LNs). Metastases to RPELNs were analyzed by site and clinicopathologic variables. Recurrence rate and post-operative complications were also evaluated by comparing the right paraesophageal lymph node dissection (RPE LND) with the non-RPE LND group. RESULTS: Central node metastases were detected in 57 (49.1%) patients; paratracheal and pre-tracheal lymph node metastases, total RPE LN metastases, and metastases only in RPE LN occurred in 50 (43.1%), 18 (15.5%), and 5 (4.3%) patients, respectively. Age, tumor size, tumor longitudinal location, extrathyroidal extension, and multicentricity were insignificant in RPE LN metastasis (P>.05). Although there was no significant statistical difference, tumors with lymphatic invasion and larger tumors (>1 cm) had more frequent RPE LN metastases. RPE LN metastases were frequent in deeply located tumors instead of superficially located tumors (P=0.015). Compared with the non-RPE LND group, the incidence of post-operative complications (transient hypocalcemia and vocal cord palsy) was not significantly different and there was no recurrence in both groups during the follow up period. CONCLUSION: The metastatic rate of the right paraesophageal lymph nodes was 15.5%; 83.3% of these were macrometastatic. Prophylactic RPE dissection compared with the non-RPE LND group, however, did not show a survival difference for 5 years.
