Ki-1 positive anaplastic large cell lymphoma is a newly described high-grade lymphoma and is defined by histopathological and immunologic criteria. We experienced a case of systemically involving Ki-1 positive anaplastic large cell lymphoma in a 44 year-old female which initially manifested as pleural effusion. Abdominopelvic CT scan showed the evidence of marked lymphadenopathy in retroperitoneal and both external and inguinal lymph nodes. On cytologic examination of pleural fluid, tumor cells revealed pleomorphic large isolated cells with prominent nucleoli and abundant cytoplasms. The nuclei were large with irregular profiles including some deep invaginations. Also, occasional multilobed/multinucleated and binucleated nuclei were seen. Immunohistochemical examination was performed to differentiate from the undifferentiated adenocarcinoma, Hodgkin's disease, non-Hodgkin's lymphoma and malignant histiocytosis. The neoplastic cells were positive for leukocyte common antigen, CD3, CD30(Ki-1) but negative for cytokeratin, epithelial membrane antigen, and CD15. A histologic diagnosis of Ki-1 positive anaplastic lymphoma was made by biopsies of the inguinal lymph node, polypoid lesions of the stomach and cecum.

Background & Objectives: In patients with gastric cancer, the most frequently reported family history of cancer also involves the stomach. The aim of this study was to assess the presence of gastric precancerous lesions in first-degree relatives of patients with gastric cancer and to compare the obtained results with those of individuals with no such family history. Methods: Between 2007 and 2009, 503 consecutive persons more than 30 years old were enrolled in the study covering siblings, parents or children of patients with confirmed adenocarcinoma of stomach. The control group was made up of 592 patients who were synchronously undergoing upper gastrointestinal endoscopy for evaluation of dyspepsia without gastric cancer or any family history. All subjects were endoscopically examined. Results: The overall prevalence of Helicobacter pylori was 77.7% in the cancer relatives and in 75.7% in the control group. Chronic gastritis was found in 90.4% vs. 81.1% (P<0.001). Regarding histological findings, 37(7.4%) of the study group had atrophy vs. 12(1.7%) in the control group (P<0.001), while no difference was observed for intestinal metaplasia (20.3%vs. 21.6%, P=0.58). Dysplasia were shown in 4% of cancer relatives but only 0.4% of the control group (P<0.001). There was no gender specificity. Conclusions: Findings of our study point to great importance of screening in relatives of gastric cancer patients in Iran.

Skeletal muscle metastasis of gastric cancer is extremely rare and is associated with various symptoms. Here, we report on a 60-year-old woman with right hip pain after excessive walking. Two years earlier, the patient had been treated for advanced gastric cancer (surgery, adjuvant chemotherapy). Upon magnetic resonance imaging, diffuse muscle swelling and high signal intensity were observed in T2-weighted images of the right hip muscle. However, the FDG uptake in the right gluteal muscles was not obviously increased. Pathological examination of muscle biopsy revealed metastatic adenocarcinoma of stomach origin. The patient was treated with chemotherapy, and the swelling and pain in the right hip are progressively improving.

This study was performed to observe the components, antioxidative, antimutagenic and cytotoxic effects of the mineral water using AOAC method, DPPH free radical donating method, Ames test and SRB assay. Mineral water contained eleven kinds of minerals among the total seventeen components and sodium and potassium ion were main components. Mineral water showed electron donating activities ($175.9{\mu}g$). The inhibition rate of mineral water ($200{\mu}g/plate$) in the Sallmonella typhimurium TA98 strain showed $54\%$ against the mutagenesis induced by Trp-P-1. In addition, same concentration of mineral water the Sallmonella typhimurium TA100 strain showed highest $67\%,\;65.8\%\;and\;63\%$ inhibition against $B({\alpha})P$, 4NQO and Trp-P-1, respectively. The cytotoxic effects of mineral water against the cell lines with Human lung carcinoma (A549), Human breast adenocarcinoma (MCF-7), Human stomach adenocarcinoma (AGS) and Human cervical adenocarcinoma (Hela) were inhibited with the increase of the mineral water. The treatment of $50{\mu}g/well$ of mineral water showed cytotoxicities of $66\%,\;47.6\%,\;37.7\%\;and\;45.6\%$ against A549, MCF-7, AGS and Hela.

This study was conducted to screen the biological activity of urushiol in the sap of lac tree(Rhus verniciflua STOKES) which has been used in traditional folk remedies. Cytotoxic activity of urushiol was screened with L1210(mouse luekemia cell), PC-9(human lung adenocarcinoma cell), A427(human lung adenocarcinoma cell) and KATO III (human stomach adenocarcinoma cell) The stepwise hexane : acetone eluent fractions of the urushiol were obtained by the silica gel adsorption column chromatography and added to the culture media containing L1210, PC-9. A427, and KATO III, respectively. A hexane : acetone(90 : 10, v/v) eluent fraction of them showed the lowest 50% inhibition concentration($IC_{50}$) of $0.018{\mu}g/m{\ell}$ for the cell line of A427. Much lower level of $IC_{50}$ of the hexane : acetone(90 : 10, v/v) eluent fraction of the urushiol showed the equal inhibition effect with tetraplatin(i.e., anti-cancer drug of platinum complexes) on the cancer cell lines as follows ; 3.4 times lower for L1210, 3.9 times lower for PC-9, and 105.5 times lower for A427. However, $IC_{50}$ of the hexane : acetone(90 : 10 v/v) eluent fraction for KATO III was exceptionally 3.9 times higher than that of tetraplatin.

Increased risk of gastric cancer has been reported in patients with chronic atrophic gastritis that develops in conjunction with pernicious anemia. We report here a case of a gastric adenocarcinoma associated with pernicious anemia. A 40-year-old female patient had been diagnosed with anemia 6 years earlier at a local hospital. One month ago, she visited our hospital for aggravated dizziness and newly developed epigastric soreness. Her blood hemoglobin level was 4.2 g/dl, and a gastroscopic work-up for anemia discovered a 2.5-cm-sized, slightly elevated mucosal lesion at the anterior wall of the high body in the stomach. The biopsy of this lesion revealed a moderately-differentiated adenocarcinoma. She underwent a total gastrectomy with a Roux en Y esophagojejunostomy with D2 lymph node dissection. The final stage of the gastric carcinoma was identified as T1N0M0. Based on this experience, we recommend that a follow-up gastroscopy be performed in patients with pernicious anemia with atrophic gastritis because of the increased risk of gastric cancer in patients with pernicious anemia.

This study was performed to observe the antimutagenic and cytotoxic activities of methanol extract of kochujang added with sea tangle and deep sea water salts (SDK) and kochujang added with sea tangle (SK) using the Ames test and SRB assay, respectively. The direct antimutagenic effect of SDK and SK methanol extracts were examined by Ames test using Salmonella Typhimurium TA98 and TA100. In the Ames test, methanol extract of SDK and SK alone did not exhibit mutagenicity and most of the samples showed high antimutagenic effects against mutation induced by N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) and 4-nitroquinoline-1-oxide (4NQO). Methanol extract of SDK ($200{\mu}g$/plate) showed approximately 71.4% inhibitory effect on the mutagenesis induced by 4NQO against TA98 strain; whereas 56.1% and 83.6% inhibitions were observed on the mutagenensis induced by 4NQO and MNNG against TA100 strain. The cytotoxic effects of SDK and SK increased with increasing sample concentration against human cervical adenocarcinoma (HeLa), human hepatocellular carcinoma (Hep3B), human breast adenocarcinoma (MCF-7), human stomach adenocarcinoma (AGS), and human lung carcinoma (A549). The SDK at the concentration of 1 mg/ml showed cytotoxicities of 61.5%, 61.3%, 51.4%, 57.9% and 77.7% against HeLa, Hep3B, MCF-7, AGS and A549, respectively. In contrast 1 mg/ml treatment of SDK and SK methanol extract had only $2{\sim}38%$ cytotoxicity on human transformed primary embryonal kidney cell (293).

Gastric carcinoma rarely presents as a perforation, but when it does, is perceived as advanced disease. The majority of such perforations are Stage III/IV disease. A T1 gastric carcinoma has never been reported to perforate spontaneously in English literature. We present a 56 year-old Chinese male who presented with a perforated gastric ulcer. Intra-operatively, there was no suspicion of malignancy. At operation, an open omental patch repair was performed. Post-operative endoscopy revealed a macroscopic Type 0~III tumour and from the ulcer edge biopsy was reported as adenocarcinoma. Subsequently, the patient underwent open subtotal gastrectomy and formal D2 lymphadenectomy. The final histopathology report confirms T1b N0 disease. The occurrence of a perforated early gastric cancer reemphasises the need for vigilance, including intra-operative frozen section and/or biopsy, as well as routine post-operative endoscopy for all patients.

Gastric metastasis from ovarian carcinoma is extremely rare and the prognosis for patients is poor. We report a case of multimodal treatment improving the survival time of a patient with gastric metastasis from ovarian cancer. A 73-year-old woman with known serous ovarian cancer was admitted to the hospital due to epigastric pain and dyspepsia. On esophagogastroduodenoscopy, a protruding mass was noted at the gastric antrum. She underwent distal gastrectomy with Billroth I anastomosis and lymph node dissection, including the para-aortic lymph nodes. The final pathology revealed gastric metastasis from ovarian serous adenocarcinoma. In this case, after cytoreductive surgery, chemotherapy was performed each time a recurrence was diagnosed, and remission was accomplished. She survived for 108 months after the first diagnosis of the metastatic tumor in the stomach. Multimodal treatment of metastatic lesions since the first diagnosis allowed the patient to survive longer than those in previous reports.
