  • Chelidonii Herba (Baekgulchae in Korean: CHE), a commonly used herb in Korea, Japan and China, is widely used in the treatment of stomach cancer, jaundice, gastric ulcer, edema and pain of stomach. In the present study, we demonstrated that CHE induces apoptosis in AGS cells, human stomach adenocarcinoma cell line. One of the most important recent advances in cancer research is the recognition that apoptosis plays a major role in both tumor formation and treatment response, In this study, CHE caused a decrease of viability in AGC cells. When AGS cells were treated with CHE, cells showed dose-dependent manner apoptotic cell death. Increased apoptotic cell death, exposured to CHE, resulted from induction of Bad translocation to mitochondria, cytochrome-c release from mitochondria to cytosol, activation of caspase-3, 8, 9, and PARP cleavage. These results suggest that CHE may be potential therapeutic approach in the clinical management of stomach adenocarcinoma.

  • This study is a report about a specific patient whose primary stomach adenocarcinoma metastasized to uterine cervix adenocarcinoma. A thirty-nine year old female patient was initially diagnosed as having metastatic adenocarcinoma in the supraclavicular lymph node. Upon further examination, she was diagnosed with stomach adenocarcinoma. 8 months later, a cervix punch biopsy was performed. The stains used for examination were H&E stain, PAS stain, Alcian blue stain, Mucicarmine stain, Papanicolaou's (Pap.) stain, and as immunohistochemical stains, cytokeratin 7 and 20 were done. In the H&E stain, the tumor cells showed prominent and eccentric nuclei, thin nuclear membrane in abundant mucous cytoplasm, and cylinder shape. In the PAS stain, intracytoplasmic mucin vacuoles were stained with pink, and in Alcian blue and Mucicarmine stains, intracytoplasmic mucin vacuoles were stained with blue and red. As in the above results, she was diagnosed with undifferentiated adenocarcinoma. As found on the cytologic smear preparation of the uterine cervix stained by Papanicolaou's stains, the background was relatively clear, the number of malignant cells was relatively low, and large and eccentric nuclei in abundant cytoplasm were observed. Upon observing the tissue preparation of the uterine cervix biopsy by H&E stain, a clear background, large and eccentric nuclei, and a signet ring cell types were observed, and the number of malignant cells were fewer than in the primary uterine cervix adenocarcinoma. The vacuoles in cytoplasm were observed. The nuclear membrane and chromatin were thick and very rough, and upon observation by cytokeratin 7 and 20 of immunohistochemical stain, the tumor cells indicated a positive rate of 70% and 20%, respectively. According to these results, also she was diagnosed with metastasized uterine cervix adenocarcinoma. In summary of the results of pathologic findings on stomach biopsy and cytologic, histopathologic, and immunohistochemical finding on uterine cervix biopsy, the adenocarcinoma of her uterine cervix could assert the adenocarcinoma of signet ring cell type that was metastasized from the primary undifferentiated adenocarcinoma in stomach.

  • Metastasis of gastric adenocarcinoma to the prostate gland is extremely rare. Herein, we report a case of gastric adenocarcinoma in a 56-year-old man with prostatic metastasis diagnosed through the analysis of biopsy specimens from representative lesions in the stomach and prostate gland. Immunohistochemistry of the prostatic tissue showed positive staining for cytokeratin 7 and negative staining for prostate-specific antigen (PSA), whereas the serum PSA level was normal, confirming the diagnosis of prostatic metastasis from carcinoma of the stomach.

  • We report a rare case of the coexistence of a gastric small cell neuroendocrine carcinoma with a gastric adenocarcinoma. A 62-year-old man presented with epigastric soreness for 1 month. Esophagogastroduodenoscopy revealed a Borrmann type I tumor at the lesser curvature of the lower body of the stomach. The patient underwent a distal gastrectomy with D2 lymph node dissection and the resected specimen exhibited a $3.5{\times}3.5$ cm sized, fungating lesion. Two separated, not intermingling, lesions with non-adenocarcinoma components encircled by well differentiated adenocarcinoma components were identified microscopically. The non-adenocarcinoma component showed neuroendocrine features, such as a solid and trabecular pattern, and the tumor cells showed a high nuclear grade with minimal cytoplasm, indistinct nucleoli, and positive response for synaptophysin, CD56. The final pathological diagnosis was a gastric mixed exocrine-endocrine carcinoma (MEEC) composed of an adenocarcinoma and small cell neuroendocrine carcinoma of the collision type.

  • Although the most commonly encountered orbital tumor is metastatic tumor, adenocarcinoma of stomach metastasized to the optic nerve is rarely reported. The authors discuss a rare case of metastatic adenocarcinoma of left optic nerve with a review of literature. A 44-year-old man presented with decreased visual acuity of left eye for 3 months. Neurologic examination revealed left optic neuropathy. On MR imaging, a homogenously wellenhanced mass surrounding left optic nerve around optic canal was noticed. The X-rays and the whole body bone scan sho-wed multiple bony metastasis. Subtotal removal was performed via combined subfrontal and pterional approach and metastatic adenocarcinoma from the stomach was confirmed histologically. Postoperative course was uneventful, but there was no improvement of visual acuity.

  • 위암의 한 아형인 간양 선암은 조직학적으로 간세포암종과 형태학적으로 유사하며 알파태아단백 생산을 특징으로 한다. 간양 선암의 또 하나의 특징은 간과 림프절로의 조기 전이를 함으로써 불량한 예후를 갖는다는 것이다. 저자들은 간전이를 동반한 위의 간양 선암 1예를 보고하고자 한다. 소화불량을 주소로 내원한 52세 남자 환자는 위내시경 검사상 Borrmann 제2형 병변이 위암이 의심되었다. 환자의 혈청 알파태아단백은 123 ng/ml로 증가되어 있었다. 근치적 위아전절제술과 간우엽절제술을 시행하였고 조직학적 소견상 위의 병변은 점막하층에 국한된 간양 선암이었으며 간의 병변은 위로부터 전이된 선암이었다. 결국 환자는 위암 4기(T1N1M1)로분류되었다. 위의 간양 선암은 조기병변에서도 불량한 예후군으로 분류될 수 있다.

  • A composite glandular/exocrine-endocrine carcinoma of the gastrointestinal tract is characterized by the co-existence of two adjacent, but histologically-distinct tumors in an organ. Composite glandular/exocrine-endocrine carcinomas are a special type of tumor comprised of common adenocarcinomas and neuroendocrine components that account for at least one-third of the entire tumor area. Composite tumors have been reported in a range of organs, but are relatively rare in the stomach. We report a case of a composite neuroendocrine carcinoma with an adenocarcinoma of the stomach (mixed exocrine-endocrine carcinoma), which was misdiagnosed as a giant submucosal tumor preoperatively based on esophagogastroduodenoscopy and a contrast-enhanced axial computed tomographic scan.

  • Background: Gastric and esophageal cancers are among the most lethal human malignancies worldwide. Of all malignancies estimated in Iran (47,100), gastric and esophageal cancers were responsible for 7,800 and 3,500 deaths in 2008 respectively. The present study aimed to provide an image of patho-epidemiological characteristics with their trends during two past decades with emphasis on topographic, morphologic, and some demographic features. Materials and Methods: In a hospital-based retrospective study in 2009, all pathological reports from esophageal endoscopies and gastric biopsies through a 20 years period (1989-2008) were collected and analyzed in four interval periods(five years each). Also, all eligible samples in hospital archives were enrolled for further testing. Besides, demography, topography and morphology of all samples were determined and analyzed by statistical software. Results: No significant statistical difference was seen in frequency of espohageal and gastric tumors throughout the study. Esophageal cancer cases were older than gastric. Sex ratio was 2.33/1 and men had a higher rate of both esophageal and gastric tumors. Stomach cancer included 64.3% of all cases. Inferior third and end of esophagus were common locations for esophageal tumors whereas proximal stomach was common for gastric tumors. Squamous cell carcinoma and adenocarcinoma were common morphological types of tumors in esophagus and stomach respectively. Conclusions: Morphological trends showed an increase of esophageal adenocarcinoma and diffuse/intestinal ratio in stomach cancers. Trends in incidence from gastric cancer decreased based on topographic studies but we could not find a topographical trend toward cadia.

  • The causes of treatment failure in head and neck cancer are locoregional recurrence, distant metastasis and second primary cancer. The favorite sites of second primary cancer are head and neck, lung and esophagus. But, the incidence of stomach cancer in Korea is the highest of all, high incidence of stomach cancer is expected in head and neck cancer patients. We experienced 2 cases of stomach cancer after successful treatment of primary head and neck cancer at Kang Nam St. Mary's hospital. The first case was a 60-year-old male with nasopharyngeal non-keratinizing carcinoma(stage III, T1N1M0). He received three cycles of induction chemotherapy including cisplatin and 5-fluorouracil followed by radiotherapy which resulted in complete response. Five months after completion of radiotherapy. stomach adenocarcinoma(stage IV, T4N2M1) was diagnosed. He received one cycle of FAM chemotherapy and died 4 months after diagnosis of stomach cancer. The second case was a 50-year-old male with pyriform sinus squamous cell carcinoma(stage II, T2N0M0). He received curative partial pharyngolaryngectomy followed by radiotherapy which result in free of disease. Four months after completion of radiotherapy. stomach adenocarcinoma(stage IV, T4N2M1) was diagnosed. Bypass gastrojejunostomy was performed. The screening test for stomach cancer including upper gastrointestinal X-xay series and/or endoscope of the stomach should be performed periodically for the patients with head and neck cancer in Korea.

  • Cytodiagnosis of pleural and ascitic fluid is a commonly performed laboratory examination. Especially, positivity for malignant cells in effusion cytology is very effective and also presents the first sign of malignancy in unknown primary site of the tumor. We examined each 34 cases of pleural and ascitic fluid cytologic specimen diagnosed as metastatic tumor, which was selected among 964 pleural fluid cytology cases and 662 ascitic fluid cytology cases from September 1989 to June 1995. Among the pleural fluid cytology specimens examined, 34 specimens were positive in 27 patients. The lung was the most frequent primary site(44%), followed by the stomach (12%), lymphoreticular neoplasm(12%), pancreas(3%) and colon(3%). And the cases of unknown primary site with positive pleural biopsy alone were 24%. Among trio ascitic fluid cytology specimens examined, 34 specimens were positive in 29 patients. The most common primary neoplasms. were carcinomas of ovary(32%), stomach(22%), colon(6%), breast(3%), pancreas(3%), and lung(3%) and lymphoreticular neoplasms(3%) The metastatic tumor was predominantly adenocarcinoma type in both pleural(82%) and ascitic(91%) fluid. The study of metastatic adeno- carcinoma in effusion from lung, ovary, and stomach was undertaken to find distinctive features for the identification of the primary site. The smears of metastatic pulmonary adenocarcinoma had a tendency to show high grade pleomorphism and many large tight cell clusters, whereas that of the ovarian adenocarcinoma showed low grade pleomorphism with abundant intracytoplasmic vacuoles in relatively clear background. That of the stomach revealed the intermediate features.
