Abstract
Purpose: RUNX3, a novel tumor suppressor, is frequently inactivated in gastric cancer. In the present study, we examined the pattern of RUNX3 expression in gastric cancer cells from gastric cancer specimens and the impact of its alteration on clinical outcome. Materials and Methods: A total of 124 samples of both gastric cancer and normal tissue were obtained from 124 patients who underwent curative gastrectomy at the Seoul Medical Center from January 2001 to December 2005. RUNX3 expression was determined by immunohistochemical staining, and the results were analyzed. Statistical analysis wabased on clinicopathological findings and differences in survival rates. Results: The mean age of the patients was 61 years, and the male:female ratio was 1.9:1. The expression rate of RUNX3 was 59.7% (74/124). The expression rate was higher in differentiated gastric cancers (nucleus: 9.1%, cytoplasm: 57.6%) than in the undifferentiated types (nucleus: 5.2%, cytoplasm: 46.6%) (P=0.133). The 5-year survival rates according to RUNX3 expression determined from cancer tissue were 88.9% for the nucleus
목적: Runt-related transcription factor 3 (RUNX3)는 새로운 tumor Suppressor로써 최근 많은 연구들이 여러 암을 대상으로 진행되고 있다. 그러나 위암에 대한 임상연구는 아직까지 보고가 많지 않은 상태이다. 이에 저자들은 본 연구에서 위암조직에서의 RUNX3의 발현율과 임상적 의의에 대해 분석을 시행하였다. 대상 및 방법: 2001년 1월부터 2005년 12월까지 서울의료원에서 위암으로 근치적 수술을 시행 받은 124명을 대상으로 하였다. 이들 환자에서 적출된 위 조직으로 만들어진 파라핀 블록을 이용해 위암조직 124예를 채취하여 RUNX3 발현을 면역조직화학염색으로 확인한 후 비교분석 하였다. RUNX3 염색결과는 핵과 세포질에서 양성과 음성으로 나누어 각각 판독하였으며 통계분석은 SPSS 11.0을 사용하였다. 결과: 대상 환자의 평균 연령은 61세(
