목적 본 연구의 목적은 두경부암의 종격동 림프절 전이의 예측인자와 영상 소견을 알아보고자 함이다. 대상과 방법 이 연구에서 저자들은 두경부암 환자 중에서 종격동 림프절 전이그룹과 비전이 그룹 사이의 임상 소견 및 질병의 특성(성별, 연령, 원발성 종양 부위, 조직학적 유형, 악성종양에 대한 이전 치료이력, T-, N- 및 M- 단계, 경부 림프절 전이) 들을 비교하였다. 또한 저자들은 전이그룹에서 종격동 림프절 분류에 따라 림프절 전이의 흉부 전산화단층촬영(전이분포와 림프절 최대직경) 및 양전자방출단층촬영/전산화단층촬영(최대 표준섭취계수)의 소견을 평가하였다. 결과 두경부암 환자 470명 중 55명(11.7%)에서 150개의 종격동 station을 포함하는 종격동 림프절 전이가 발견되었다. 하인두암, 재발한 종양, T4, N2/N3, 및 M1 단계는 종격동 림프절 전이의 의미 있는 예측인자로 평가되었다. 종격동 림프절 전이의 가장 흔한 위치는 일측 station 2 (상부기관주위 림프절, 36.4%), 일측 station 11 (엽간 림프절, 27.3%), 일측 station 10(폐문 림프절, 25.5%) 순이었다. 결론 하인두암, 재발성 종양 및 높은 TNM 단계인 경우, 두경부암의 종격동 림프절 전이 가능성을 고려하여야 한다.

Gastric cancer is one of the most common cancers in Korea and the world. Since 2004, this is the 4th gastric cancer guideline published in Korea which is the revised version of previous evidence-based approach in 2018. Current guideline is a collaborative work of the interdisciplinary working group including experts in the field of gastric surgery, gastroenterology, endoscopy, medical oncology, abdominal radiology, pathology, nuclear medicine, radiation oncology and guideline development methodology. Total of 33 key questions were updated or proposed after a collaborative review by the working group and 40 statements were developed according to the systematic review using the MEDLINE, Embase, Cochrane Library and KoreaMed database. The level of evidence and the grading of recommendations were categorized according to the Grading of Recommendations, Assessment, Development and Evaluation proposition. Evidence level, benefit, harm, and clinical applicability was considered as the significant factors for recommendation. The working group reviewed recommendations and discussed for consensus. In the earlier part, general consideration discusses screening, diagnosis and staging of endoscopy, pathology, radiology, and nuclear medicine. Flowchart is depicted with statements which is supported by meta-analysis and references. Since clinical trial and systematic review was not suitable for postoperative oncologic and nutritional follow-up, working group agreed to conduct a nationwide survey investigating the clinical practice of all tertiary or general hospitals in Korea. The purpose of this survey was to provide baseline information on follow up. Herein we present a multidisciplinary-evidence based gastric cancer guideline.
