목적: 내시경점막하박리법(endoscopic submucosal dissection, ESD)은 큰 병소를 일괄절제할 수 있다는 장점이 있으나 시간이 오래 걸리고, 출혈과 천공과 같은 합병증의 발생률이 높다. 저자들은 위선종과 조기위암에서 ESD의 치료성적을 분석하여 ESD의 효율성과 안전성에 대해 알아보고자 하였다. 대상 및 방법: 2003년 1월부터 2005년 12월까지 동아대 학교병원에 입원하여 위선종 및 조기위암으로 진단되어 ESD을 받은 101명의 환자에서 총 101예의 병변을 대상으로 후향으로 조사하였다. 결과: 1) ESD가 시행된 병변의 평균 크기는 2.58 cm였다. 2) ESD군의 일괄절제율은 90.1%였으며, 이는 병변의 크기가 큰(≥3 cm) 경우에 유의하게 감소하였다. 3) 완전절제율은 83.2%로, 병변 크기에 따른 차이는 없었으나 저도형성이상과 고분화형조기위암에서 특히 완전 절제율이 높았다. 4) 출혈은 41.6%로 응급 수술이 필요할 만큼의 유의한 출혈은 없었고, 내시경 치료로 쉽게 지혈하였다. 5) 재발률은 2.0%였다. 결론: ESD법은 조기위암과 위선종의 치료법으로 효과적이고 비교적 안전한 방법으로 향후 장기적인 추적 관찰이 필요하다. Background/Aims: Endoscopic Submucosal Dissection (ESD) is a new endoscopic mucosal resection (EMR) technique which enables en bloc resection even in large and depressed lesions. The aims of this study were to assess the therapeutic efficacy and the safety of ESD in gastric adenoma and in early gastric cancer (EGC). Methods: We analyzed 101 lesions in 101 patients. ESD with insulated-tipped (IT) knife were performed in 52 adenomas and 49 EGCs from January 2003 to December 2005 in Dong-A University Hospital. Results: The mean size of the lesion was 2.58 cm (0.7-4.5 cm). En bloc resection rate was 90.1% which was influenced by size (p>0.05). Complete resection rate was 83.2% even in large or in malignant tumors (p>0.05). Bleeding after ESD occurred in 41.6%. Tumor recurrence rate was 2.0%. Conclusions: ESD with IT knife is effective for the treatment of EGC and gastric adenoma even in large or in malignant lesions without definite increased risk of complications.

Background/Aims: Endoscopic submucosal dissection (ESD) is commonly used for radical resection of gastric adenoma and mucosal cancer, but there is about 30% of discrepancy rate between the histology of the endoscopic biopsy and that of the resected specimen obtained from the same lesion by ESD. The aim of this study was to clarify the clinical significance of IL-6, VEGF, CRP before ESD. Methods: We investigated the correlation between serum IL-6, VEGF, CRP level and discrepancy rate of gastric neoplastic lesions (10 low-grade dysplasias, 18 high-grade dysplasias, and 25 early gastic cancers). Results: Serum levels of IL-6 in gastric adenoma and mucosal cancer patients were significantly higher than in healthy controls (p<0.05). Especially, serum IL-6 level of high-grade dysplasia patient was significantly higher than low-grade dysplasia and mucosal cancer patients, and the positive rate, sensitivity, and negative predictive value of serum IL-6 levels were higher in high-grade dysplasia patient compared to low-grade dysplasia patient and mucosal cancer patient. Serum levels of VEGF in patients with gastric adenoma and mucosal cancer were significantly higher than healthy controls (p<0.01). Serum levels of CRP in patients with mucosal cancer were significantly higher than in the controls (p<0.05), and the positive rate, sensitivity, and positive predictive value of serum CRP levels were higher in high-grade dysplasia and mucosal cancer patients compared to low-grade dysplasia patient. Conclusions: Serum levels of IL-6, VEGF, and CRP in patients with gastric neoplastic lesions were significantly higher than healthy controls, especially, serum IL-6 level of high grade dysplasia patient was significantly higher than low-grade dysplasia and mucosal cancer patients.

Purpose: The cDNA microarray provides a powerful alternative with an unprecedented view in monitoring geneexpression levels and leads to discoveries of regulatory pathways involved in complicated biological processes. Our aim is to explore the different gene-expression patterns in gastric adenocarcinomas. Materials and Methods: By using a cDNA microarray representing 4,600 cDNA clusters, we studied the expression profiling in 10 paired gastric adenocarcinoma samples and in adjacent noncancerous gastric tissues from the same patients. Alterations in the gene-expression levels were confirmed by Vsing Northern blots and reverse-transcription PCR (RT-PCR) in all of 4 randomly selected genes. Results: Genes those were expressed differently in cancer ous and noncancerous tissues were identified. 44 (of which 26 were known) and 92 (of which 43 were known) genes or cDNA were up- and down-regulated, respectively, in more than $80\%$ of the gastric adenocarcinoma samples. In cancer ous tissues, genes related to gene/protein expression, cellcycle regulation, and metabolism were mostly up-regulated whereas genes related to the oncogene/tumor suppressor gene, cell structure/motility, and immunology were mostly down-regulated. The semi-quantitative RT-PCR results for the four genes we tested were consistent with the array findings. Conclusions: These results provide not only a new molecular basis for understanding the biological properties of gastric adenocarcinomas but also a useful resource for future development of therapeutic targets and diagnostic markers for gastric adenocarcinomas.

Purpose: Preoperative staging of gastric cancer is crucial because the treatment modality and the prognosis depend upon the stage of gastric cancer. Current treatment modalities for early gastric cancer have focused on the quality of life. Endoscopic ultrasonography (EUS) and abdominal computed tomography (CT) are commonly used diagnostic tools to evaluate the invasiveness (T stage) of the primary tumor. The purpose of this paper is to evaluate the sensitivity and the specificity of preoperative EUS and CT in comparison with postoperative pathology. Materials and Methods: From October 2001 to October 2002, EUS and abdominal CT were performed simultaneously on 75 patients who underwent radical gastric surgery for the treatment of gastric cancer. Through analyzing the clinical T stage and the pathologic T stage, We evaluated the diagnostic sensitivities and specificities of endoscopic ultrasonography and abdominal computed tomography. Results: The male-to-female sex ratio was 1 : 0.6 (males: 47, females: 28). The mean age was 55.4 years in males (range: $28\~81$) and 54.4 years in females (range: $23\∼77$). The clinical T stage based on EUS included 22 T1mm, 7 T1sm, 22 T2, and 24 T3. The clinical T stage based on CT included 20 Tx, 23 T2, and 32 T3. The permanent pathologic report confirmed 23 T1mm, 10 T1sm, 17 T2, 24 T3, and 1 T4. The sensitivity and specificity of EUS were $84.2\%\;and\;94.7\%$, respectively. However, the sensitivity and specificity of abdominal CT were $53.3\%\;and\;77.0\%$, respectively. Conclusion: Our data suggest that EUS is a very useful diagnostic tool for evaluating the T stage of gastric cancer because EUS has higher specificity than abdominal CT. Therefore, EUS may have a significant role as a preoperative diagnostic modality in patients undergoing minimally invasive surgery.

Backgroud/Aims: Gastric cancer is one of the most common malignancy in Korea. In many reports, it has been known that chemotherapy does not improve survival rate of patients with gastric cancer. However, some Japanese reports showed that chemotherapy was effective. Side effects of chemotherapy increase with escalating dosage of chemotherapy drugs. There are some reports that chronotherapy could reduce the side effects and improve the survival rate in patients with gastric or colorectal cancer. We studied the side effects of chronotherapy in patients with gastric cancer. Methods: Fourteen patients with previously untreated gastric cancer received chronomodulated 5-FU ( 900 mg/m2/day, day 1-5) and cisplatin ( 90 mg/m2, day 1). Thirteen patients of control group received 5-FU ( 600 mg/m2/day, day 1-5) and cisplatin ( 60 mg/m2, day 1) during the daytime. The side effects of the two groups were evaluated for nausea and vomiting, diarrhea, peripheral neuropathy, mucositis, leukopenia, anemia, thrombocytopenia, and serum creatinine. Results: Compared to the control group, chronotherapy-treated group showed statistically significant decrease in nausea and vomiting ( p= 0.037), but not in others. Conclusions: Although only the incidence of nausea and vomiting was decreased significantly in the chronotherapy group, chronotherapy could be effective in reducing the side effects of chemotherapy in patients with gastric cancer considering that higher doses of drugs were used in the chronotherapy-treated group.

N/A Background/Aims: This study is aimed to observe the expression of GST-z in colorectal adenomas and adenocarcinomas according to the risk and prognostic factors, and investigate the role during carcinogenesis and the possibility of clinical application as a tumor marker of colorectal neoplasm, in cornparision with the expression of p53 protein and CEA. Methods: Immuno- histochemical stain was performed in 15 cases of normal colon, 31 adenomas and 63 adenocarci- nomas. Results: The incidence of GST- expression was higher in adenocarcinoma (95.2%) than normal colon(40%), adenoma(87.1%) and adjacent norrnal mucosa to adenocarcinoma(63.5%) and the degree of the expression was also significantly different among them. In adenomas, the higher the degree of dysplasia, the higher the expression of GST-z. In adenocarcinomas, the expression was significantly decreased in relation with progression to lower histologic grade. The incidence of p53 expression was higher in adenocarcinomas(54.0%) than normal colon(0%), adenoma(25.8%) and adjacent normal mucosa to adenocarcinoma(0%) and the degree of the expression was also significantly different among them. In adenomas, the higher the degree of dysplasia, the higher the expression of p53. In adenocarcinoma, there was no sifnificant difference in relation with the histologic grade and stage. The incidence of CEA expression was higher in adenocarcinoma (96.8%) than normal colon(33.3%), adenoma(64.5%) and adjacent normal mucosa to adenocarci- norna(95.2%) and the degree of the expression was also significantly different among them. In adenomas, there was no significant difference in relation with size, amount of villous component and degree of dysplasia. In adenocarcinomas, the expression was increased in relation with progression to higher stage. The incidence of intense co-expression of GST-z and p53 in adenocarcinoma showed a tendency to be increasing in relation with progression to higher stage. But there was no statistically significant. Conclusions: It has been found from the above results that the expression of GST-z is progressively increased during colorectal carcinogenesiser. (Korean J Gastroenterol 1997;29:632-644)
