We report a case of hepatoma with duodenal metastasis in a 53 year-old male patient. Hepatoma was confirmed by fine needle aspiration cytology technique, and duodenal metastasis by gastrofiberscopic biopsy. Duodenal metastasis of hepatoma is rare. We briefly review the role of fine needle aspiration cytology technique in diagnosis of hepatoma.

Colorectal cancers often invade adjacent organs; however, direct duodenal invasion is rare. Adenocarcinoma is the most common type of colorectal cancer, but an undifferentiated carcinoma type is unusual. Herein, we present a case of undifferentiated carcinoma of the colon that directly invaded the duodenum and metastasized to distant lymph nodes. An 85-year-old female patient was admitted with a 7-cm-sized colonic mass invading the duodenum, detected by computed tomography. Positron emission tomography revealed fluorodeoxyglucose uptake in the colon, duodenum, and aortocaval lymph nodes. A large encircling mass in the ascending colon and an ulcerated mass in the duodenum were revealed by colonoscopy and esophagogastroduodenoscopy, respectively. Pathologic examinations of the colon and the duodenum revealed nonglandular, diffusely infiltrating atypical round cells, confirming undifferentiated carcinoma of the colon. The histologic type of this tumor was distinguished using immunohistochemical (IHC) markers. Finally, microscopic characteristics and IHC markers aided in identifying the histologic type of colorectal cancer.

A 51-year-old male patient had four times of massive hematochezia episode three days before arrival. Carbohydrate antigen (CA) 19-9 level was extremely elevated. Computed tomography, magnetic resonance imaging, and positron emission tomography-computed tomography identified 5.7 cm sized periampullary duodenal cancer with regional metastatic lymph nodes and vascular invasion to aberrant right hepatic artery, main portal vein, and superior mesenteric vein. Diagnosed as duodenal adenocarcinoma through endoscopic biopsy, 16 times of FOLFIRI (5-fluorouracil, leucovorin, irinotecan) was conducted. The regimen changed to XELOX (capecitabine, oxaliplatine), four times of administration was done, and the CA19-9 level dramatically decreased. The tumor decreased to 2.1 cm. After R0 laparoscopic pylorus preserving pancreatoduodenectomy, no adjuvant therapy was given. No sign of recurrence or metastasis was reported, and the patient reached complete remission after five years. We reported a case where neoadjuvant chemotherapy for locally advanced duodenal adenocarcinoma was shown to be effective.

원발성폐암의 위장관 전이, 특히 십이지장으로의 전이는 매우 드물며, 부검에서 발견되는 경우가 더 많다. 본 증례의 58세 남자는 왼쪽 등의 통증과 흉부 X-선 촬영에서 좌상엽에 종괴로 의뢰되어 경기관지폐생검 결과 폐선암을 진단 받았으며, 이후 소화불량과 상복부불편감을 호소하여 시행한 위내시경 결과 십이지장 팽대부의 점막 돌출을 발견하여 이에 대한 조직검사에서 폐선암의 십이지장 전이로 밝혀졌다.

A 10-year-old-girl was referred to our hospital due to abdominal pain. She underwent Roux-en-Y cystojejunostomy for a choledochal cyst at another hospital at the age of 3 months. Abdominal ultrasonography (USG) and computed tomography (CT) showed type I choledochal cyst and multiple gallbladder stones. Because of severe inflammation and adhesion, partial resection of the choledochal cyst and Roux-en-Y hepaticojejunostomy was performed. Two and one half years later, intermittent abdominal pain, fever, nausea and vomiting occured. Abdominal CT scan showed a polypoid nodular lesion in the remnant of the choledochal cyst and probable metastasis at segment 7 of the liver. The duodenum was obstructed by the mass. Liver biopsy revealed moderately differentiated adenocarcinoma. A palliative gastrojejunostomy was performed to relieve duodenal obstruction. She died of hepatic insufficiency 4 months later.

Purpose: To describe the clinicopathological features of gastrointestinal stromal tumors (GIST) diagnosed in our section and to perform risk stratification of our cases by assigning them to specific risk categories and groups for disease progression based on proposals by Fletcher et al and Miettinen and Lasota. Materials and Results: We retrieved 255 cases of GIST diagnosed between 2003 and 2014. Over 59% were male. The age range was 16 to 83 years with a mean of 51 years. Over 70% occurred between 40 and 70 years of age. Average diameter of tumors was 10 cms. The stomach was the most common site accounting for about 40%. EGISTs constituted about 16%. On histologic examination, spindle cell morphology was seen in almost of 85% cases. CD117 was the most useful immunohistochemical antibody, positive in 98%. Risk stratification was possible for 220 cases. Based on Fletcher's consensus proposal, 62.3 gastric, 81.8% duodenal, 68% small intestinal, 72% colorectal and 89% EGISTs were assigned to the high risk category; while based on Miettinen and Lasota's algorithm, about 48% gastric, 100% duodenal, 76% small intestinal, 100% colorectal and 100% EGISTs in our study were associated with high risk for disease progression, tumor metastasis and tumor related death. Follow up was available in 95 patients; 26 were dead and 69 alive at follow up. Most of the patients who died had high risk disease and on average death occurred just a few months to a maximum of one to two years after initial surgical resection. Conclusions: Epidemiological and morphologic findings in our study were similar to international published data. The majority of cases in our study belonged to the high risk category.

목적 : 위암치료에 있어 완전절제수술후 임상적 국소재발이 $30-40\%$에 이르는 것으로 보고되고 있으나 수술 후 항암화학요법이나 방사선 치료의 시행은 아직 그 역할이 분명치 않다. 반면 완전절제가 이루어지지 않은 위암에서는 원발병소 부위의 국소발소 위험성이 매우 높아 추가적인 국소치료의 필요성이 제기되고 있으나 이에 대한 구체적인 연구는 아직 미미한 실정이다. 이에 저자 등은 불완전 절제된 위암에서 수술후 방사선치료가 국소재발을 줄일 수 있는지, 또한 생존율향상을 얻을 수 있는지 알기 위하여 본 연구를 시행하였다. 대상 및 방법 : 1991년 7월부터 1996년 8월까지 울산의대 서울중앙병원에서 위암 진단하에 근치적 절제수술을 시행하였으나 불완전 절제된 25명의 환자에서 수술후 방사선 치료를 시행하였다. 전체 25명의 환자 중 선세포암이 23명, 평활근육종이 2명이었고, 수술은 위전절제수술(Total gastrectomy) 5명, 위부분절제술(Subtotal gastrectomy) 20명이었다. 병기별로는 I B 1명, II 2명, III A 11명, III B 10명, IV 1댕이었으며 불완전 절제부위는 원위절제면(dlstal resection margin) 17명, 근위절제면(proxlmal resection margin) 5명, 간 절제면 1명 및 기타 장기 절제면 2명이었다. 방사선 치료는 총 6회의 FP 항암화학요법중 회차와 동시에 시작되는 것을 원칙으로 하였으며 조사선량은 44.6Gy-59.4Gy 범위였고 중앙선량은 55.8Gy였다. 결과 : 1명을 제외한 모든 환자가 정해진 양의 방사선 치료를 마칠 수 있었으며, 3명의 환자에서 $15\%$ 이상의 체중감소가 있었고 중증도 3 이상의 혈액학적 독성은 5명에서 관찰되었다. 최소 추적관찰기간은 12개월이었다. 전체 25명중 12명에서 재발이 있었으며 조사야내 국소재발은 7명에서 발생하였고 이들은 문합부위재발 3명, 인접조직 3명, 임파절 1명이었다. 반면 원격전이는 10명에서 발생하였고 이들은 복막전이 6명, 간 전이 2명, 쇄골상임파절 및 대동맥 임파절등 원위임파절 전이가 3명이었다. 환자의 현 상태는 무병생존 11명, 위암과 관련 없는 사망 2명, 위암으로 인한 사망 10명, 재발상태의 생존 2명 등이다. 4년 무병생존율과 질병관련생존율(disease specific survival)은 각각 $48\%$와 $40\%$였으며 중앙생존값은 35개월, 중앙무병생존값은 26개월이었다. 원발병소 위치, T-stage, N-stage, Stage, 방사선량 등은 생존율에 별다른 영향을 미치지 못하였다. 결론 : 수술후 방사선치료와 항암화학요법은 큰 부작용 없이 시행되었으며 치료후 실패양상은 원격전이가 가장 많았고 국소재발은 7명($28\%$)에서 발생하여 문헌상 관찰된 완전절제수술후 국소재발수치과 비슷하거나 낮은 것으로 나타났다 추적관찰 기간이 짧고 환자 수가 적어 단정짓기는 어렵지만 불완전 절제수술 후 원발병소 부위에 잔류암세포가 존재하는 상태인 점을 고려할 때, 불완전 절제된 위암에서 방사선치료가 국소재발을 억제에 기여했을 가능성이 크다고 생각된다.
