Abstract

Purpose: Gastric cancer is prevalent in Korea, therefore the purpose of this study was to determine the clinicopathologic characteristics, 5-year survival rate, and prognostic factors for gastric patients who underwent gastrectomy by a single surgeon. Materials and Methods: A total of 1,435 patients diagnosed with gastric cancer who underwent gastrectomy in the Department of Korean Gastric Cancer Center at Seoul Paik Hospital between September 1998 and August 2003, and the gender, age, location and size of the tumor, visual and histologic analysis, depth of invasion, lymph node metastasis, invasion (perineural, venous, and lymphatic), and surgical method were examined retrospectively. Results: The ratio between males and females was 2.29 : 1, and the average age was 56.7 years. Based on the UICC TNM classification, the patients were distributed as follows: IA 35.4%, IB 14.1%, II 12.6%, IIIA 12.3%, IIIB 8.3% and IV 17.3%. The 5-year survival rate was 69.6%. The results of univariate analysis showed that there were significant differences in the survival rate by age, location and size of tumor, Borrmann type, level of differentiation, Lauren's classification, depth of invasion, metastasis in lymph nodes, UICC TNM stage, invasion (perineural, venous, and lymphatic), and surgical method. Based on multivariate analysis, only the depth of invasion and lymph node metastasis were independent prognostic factors. Conclusion: Although various clinicopathologic characteristics affect the prognostic factors of the patients with gastric cancer, the results of this study showed that the stage of disease, such as depth of invasion and metastasis in lymph nodes, are the most critical factors. There is a need to establish the diagnosis of gastric cancer early and to study and develop various treatment methods based on the diagnostic factors in order to improve the survival of patients with gastric cancer.

목적: 위암은 한국에서 제일 흔한 암으로 저자들은 단일 술자에 의해 위절제술을 시행받은 환자들을 대상으로 임상병리학적 특성 및 5년 생존율과 이에 따른 예후인자를 알아보고자 한다. 대상 및 방법: 1998년 9월부터 2003년 8월까지 만 5년간 위암으로 진단되어 인제대학교 서울백병원 한국위암센터에서 위절제술을 시행한 위암환자 1,435예의 환자를 대상으로 성별 및 연령, 종양의 위치 및 크기, 육안적 분류 및 조직학적 분류, 위벽 침윤도, 림프절 전이, 혈관, 신경초, 림프관 침윤 및 수술 방법 등의 인자들을 후향적으로 조사하였다. 결과: 남녀 비는 2.29 : 1이었고 평균 연령은 56.7세였으며 UICC TNM Stage IA 35.4%, Stage IB 14.1%, Stage II 12.6%, Stage IIIA 12.3%, Stage IIIB 8.3%, Stage IV 17.3%였고 전체 5년 생존율은 69.6%였다. 단변량 분석 결과 연령, 종양의 위치, 종양의 크기, Borrmann type, 분화도, Lauren 분류, 위벽 침윤도, 림프절 전이, UICC TNM 변기, 신경초 침윤, 혈관 침윤, 림프관 침윤, 수술방법에 따라 생존율에 유의한 차이가 있었다. 다변량 분석결과 위벽 침윤도, 림프절 전이만0| 독립적인 예후인자였다. 결론: 다양한 임상병리학적 특성들이 위암환자의 예후에 영향을 주지만 이들 인자들 중 결국 위벽 침윤도와 림프절 전이, 즉 병기가 예후에 가장 중요함을 알 수 있었다. 따라서 위암환자 생존을 향상을 위해서 조기 검진을 통한 위암의 조기 발견과 예후 영향인자에 대한 다각적인 치료 방법이 연구, 개발되어야 하겠다.
