A 78-year-old man underwent laparoscopy-assisted total gastrectomy for gastric cancer (pT3N0M0). Multiple port sites were used, including a 10 mm port for a videoscope at the umbilical point and three other working ports. During the six-month follow-up evaluation, a 2 cm enhancing mass confined to the muscle layer was found 12 mm from the right lower quadrant port site, suggesting a metastatic or desmoid tumor. Follow-up computed tomography imaging two months later showed that the mass had increased in size to 3.5 cm. We confirmed that there was no intra-abdominal metastasis by diagnostic laparoscopy and then performed a wide resection of the recurrent mass. The histologic findings revealed poorly differentiated adenocarcinoma, suggesting a metastatic mass from the stomach cancer. The postoperative course was uneventful, and the patient completed adjuvant chemotherapy with TS-1 (tegafur, gimeracil, and oteracil potassium). There was no evidence of tumor recurrence during the 50-month follow-up period.

Multiple primary malignant neoplasms occur relatively frequently today and are important especially in the head and neck area for they usually carry a bad prognosis. Detection of a synchronous primary tumor at the time of initial work-up is crucial both for management and final outcome. The first case was a T1 hypopharyngeal cancer with a mid-esophageal second primary who complained of a huge neck node. The second case was a T3 hypopharyngeal cancer who was initially seen by the chest surgeons for a large lower esophageal tumor. The third case was a patient previously operated for stomach adenocarcinoma three years ago, who had newly developed symptoms like dysphagia and hoarseness, and was diagnosed as hypopharyngeal T3 with oropharyngeal second primary cancer. Three cases were all heavy smokers and had histories of heavy alcohol consumption. They were all treated at the same sitting by en-block resection of the involved organs and postoperative radiation therapy. The authors have recently experienced 3 cases of synchronous second primary cancers in association with hypopharyngeal cancer and a report is made.

Cytologic diagnosis of reactive or malignant effusion is sometimes difficult. Especially, differentiation of benign reactive mesothelial cells from malignant cells in body effusion is more difficult. Recently, immunohistochemistry has been used to diagnose difficult cases. Phospholipase $C(PLC)-{\gamma}1$ is one of the isoenzyme of the PLC which plays central role in signal transduction involving cellular growth, differentiation and transformation by phosphorylating many protein component. Increased expression of $PLC-{\gamma}1$ in human breast carcinoma, colorectal carcinoma and stomach cancers are reported. To evaluate the efficacy of positive $PLC-{\gamma}1$ immunostaining in the diagnosis of malignancy in effusions, paraffin-embedded cell blocks of pleural fluid and ascites from 10 patients(5 metastatic adenocarcinomas, and 5 reactive mesothelial cells) were immunostained with a monoclonal antibody to $PLC-{\gamma}1$. $PLC-{\gamma}1$ immuostained all the adenocarcinomas in cell block(5/5) with intense membrane pattern, however, none of the reactive mesothelial proliferations stained with the diagnostic membrane pattern. Thus, our study strongly supports the conclusion that $PLC-{\gamma}1$ immunopositivity is likely to become a useful adjunct for the diagnosis of malignancy in effusions.

Prostate cancer is the second most common cause of cancer death in men in the United States. The most common sites of metastasis include the bone, lymph nodes, lung, liver, pleura, and adrenal glands, whereas metastatic prostate cancer involving the gastrointestinal tract has been rarely reported. A 64-year-old African-American man with a history of prostate cancer presented with anemia. He reported the passing of dark colored stools but denied hematemesis or hematochezia. Colonoscopy revealed circumferential nodularity, and histology demonstrated metastatic carcinoma of the prostate. Esophagogastroduodenoscopy showed hypertrophic folds in the gastric fundus, and microscopic examination revealed tumor cells positive for prostate-specific antigen. Bone scanning and computed tomography of the abdomen and pelvis did not show metastasis. It is crucial to distinguish primary gastrointestinal cancer from metastatic lesions, especially in patients with a history of cancer at another site, for appropriate management.

Synchronous gastric cancer and adenomatous colorectal polyp in patients with Klebsiella pneumoniae-induced pyogenic liver abscess (KP-PLA) and bacteremia is a rare presentation. A 58-year-old man with a 6-month history of diabetes mellitus (DM) presented with febrile sensation and dull abdominal pain in the right upper quadrant of the abdomen. Subsequent to laboratory test results and abdominal computed tomography findings, KP-PLA with bacteremia was diagnosed. After intravenous antibiotic administration, his symptoms improved, and upper endoscopy and colonoscopy were performed to evaluate the cause of KP-PLA. Biopsy specimens of the prepyloric anterior wall revealed a moderately differentiated adenocarcinoma. Endoscopic mucosal resection of the colon revealed high-grade dysplasia. Early gastric cancer (EGC) and adenomatous colorectal polyps with high-grade dysplasia concomitant with KP-PLA and bacteremia were diagnosed in our patient who had DM. Intravenous antibiotic treatment for KP-PLA, subtotal gastrectomy for EGC, and colonoscopic mucosal resection for the colon polyp were performed. After 25 days of hospitalization, subtotal gastrectomy with adjacent lymph node dissection was performed. Follow-up ultrasound imaging showed resolution of the abscess 5 weeks post-antibiotic treatment, as well as no tumor metastasis. Upper gastrointestinal endoscopy and colonoscopy should be performed to evaluate gastric cancer in patients with PLA or bacteremia, accompanied with DM or an immunocompromised condition.

Background: Gastric cancer is one of the most common causes of cancer death in Taiwan. The literature has previously shown that age, tumor site, T categories, and number of metastatic nodes significantly affect prognosis. The aim of this study was to determine the long-term survival of patients with gastric cancer, as well as the effect of particular prognostic factors on survival. Materials and Methods: This was a survival analysis study with retrospective design. We reviewed the records of 64 patients with adenocarcinoma of the stomach who had undergone gastrectomy with curative intent between 2009 and 2012 at a teaching hospital in southern Taiwan. Data extracted from patient documents included age, gender distribution, tumor location, and pathological grading. Results: The median follow-up time was 4 years, and there were 31 deaths attributed to gastric cancer. Kaplan-Meier analysis revealed that retrieval of less than 15 lymph nodes from a patient was a significant predictor of survival. A significant predictor of poorer survival was higher pathological grading. Conclusions: Our results indicate that the number of lymph nodes retrieved and pathological grading could be viewed as crucial prognostic factors affecting the survival of individuals with gastric cancer.

A new series of highly water soluble platinum(II) complexes {Pt(II)[1,3-bis(phenylthio) propane](trans- -1,2-diaminocyclohexane) (PC-1) and Pt(II)[1,3-bis-(phenythio)propane] cis-1,2-diaminocyclohexane(PC-2)} were synthesized, and characterized by their elemental analysis and by various spectroscopic techniques[infrared(IR), 13C-nuclear magnetic resonance (NMR)]. In vitro antitumor activity of new Pt(II) complexes was tested against P-388 and L-1210 mouse lymphocytic leukemia cell lines, PC-14 / P, PC-14/ADM and PC-14 / CDDP human pulmonary adenocarcinima, DU-145 human prostate carcinoma, HT-1376 human bladder carcinoma, ZR-75-1 human breast carcinoma, MKN-45/P and MKN-45/CDDP human gastric adenocarcinoma cell lines using colorimetric MTT[3-(4,5-dimethyl thiazol-2-yl)-2.5-diphenyltetrazoliumbromide] assay for cell survival and proliferation. PC-1 showed active against L-1210, P-388 leukemia, human lung, stomach, prostate, bladder and breast cancer cell lines, and the antitumor activity of these compounds were comparable or superior to those of PC-2 and displatin. The nephrotoxicities of PC-1 and PC-2 were found quite less than that of cisplatin using MTT and [3H] thymidine uptake in rabbit proximal tubule cells and human kidney cortical cells. Based on these results, this novel platinum (II) complex compound (PC-1) represents a valuable lead in the development of a new anticancer chemotherapeutic agent capable of improving antitumor activity and low nephrotoxicity.

Gastric cancer that mimics a submucosal tumor is rare. This rarity and the normal mucosa covering the protuberant tumor make it difficult to diagnosis with endoscopy. We report two cases of advanced gastric cancer that mimicked malignant gastrointestinal stromal tumors preoperatively. In both cases, the possibility of cancer was not completely ruled out. In the first case, a large tumor was suspected to be cancerous during surgery. Therefore, total gastrectomy with lymph node dissection was performed. In the second case, the first gross endoscopic finding was of a Borrmann type II advanced gastric cancer-like protruding mass with two ulcerous lesions invading the anterior wall of the body. Therefore, subtotal gastrectomy with lymph node dissection was performed. Consequently, delayed treatment of cancer was avoided in both cases. If differential diagnosis between malignant gastrointestinal stromal tumor and cancer is uncertain, a surgical approach should be carefully considered due to the possible risk of adenocarcinoma.

연구배경: 전이성 흉막선암은 악성 경과를 취하고, 고령인 경우가 많고, 그 외에 경제적 이유 등으로 인하여 적극적인 진단 및 치료가 환자에게 실질적인 도움이 될 지 의문이다. 이에 저자들은 우리 나라에서의 전이성 흉막선암 환자들의 임상경과를 관찰하여 진단적 검사및 수기시행의 의미, 치료의 효과, 예후 등을 판정하고자 본 연구를 시행하였다. 방법: 1990년 1월부터 1994년 12월에 걸쳐 전주 예수병원 방문 환자 중 흉수 세포진(106명) 혹은 흉막생검(22명)에서 전이성 흉막선암으로 확진되었던 환자 113명을 대상으로 후향적으로 조사하였다. 결과 1) 전체 113명 중 남자 59명(52.2%), 여자 54명(47.8%) 이었고, 평균 연령은 $57.4{\pm}12.1$세 였다. 2) 원발병소는 전체적으로 폐암 46.9%(53/113), 위암 20.4%(23/113), 유방암 11.5%(13/113) 순이었고, 원발병소를 규명하지 못한 경우가 6.2%(7/113) 있었으며, 남자는 폐암(55.9%, 20/59), 위암(28.8%, 17/59), 여자는 폐암(37.0%, 20/54), 유방암(24.1%, 13/54)이 많았다. 3) 임상증상은 호흡곤란(69%), 기침(61%), 흉통(50%), 체중감소(50%), 식욕부진(49%), 객담(43%), 권태(30%) 등의 순이었다. 4) 흉수 소견은 94.4%(102/108)가 삼출성, 36~53%(39~58/109)가 혈성, 74.3%(84/113)가 일측성이었고, 백혈구 중 임파구가 $71{\pm}27%$로 우세하였다. 5) 66명 중 40명(60.6%)에서 CEA치가 흉수 혹은 혈청에서 10ng/ml 이상으로 증가하였고, 60명 중 57명(95%)에서 흉수 ADA치가 40 U/L 미만이었다. 6) 수술적요법을 제외한 여러 가지 치료가 시행되었으나 생존기간 연장의 효과가 있었는지는 의문이다. 7) 평균 생존기간은 $12.7{\pm}13.5$주였다. 결론: 이상의 연구로 볼 때, 이 질환은 아직 효과적인 치료법이 없고, 매우 악성경과를 취하는 질환이기 때문에 적극적인 검사 및 진단 수기의 진행은 특이적인 치료가 가능한 원발병소의 조기 발견과 치료 및 예방 등에 목적을 두어야 할 것이며, 생존기간의 연장 및 생존기간동안 삶의 질을 향상시키기 위한 노력도 병행되어야 할 것으로 생각된다.
