11/62. A self-expandable metallic stent in combination with cholangioscopic microwave coagulation therapy and chemotherapy with oral TS-1 against obstructive jaundice due to recurrent gastric cancer: a case report of successful treatment.

    Obstructive jaundice is a terminal symptom of gastric cancer. A 45-year-old female patient had a recurrent gastric cancer at the pancreas head and it caused obstructive jaundice. She was treated with percutaneous transhepatic cholangio-drainage, followed by radiotherapy and chemotherapy with cisplatin, epirubicin and 5-FU, which resulted in a prominent response and a self-expandable metallic stent was placed into the bile duct. After 11 months, however, the tumor recurred and the bile duct was obstructed again by an invading tumor. She was retreated with percutaneous transhepatic cholangio-drainage for jaundice, followed by chemotherapy with oral TS-1. Her recurrent tumor dramatically responded again, and cholangioscopic microwave coagulation therapy was applied for the first time through a cholangio-drainage route and an additional metallic stent was inserted into the bile duct. After these therapies she has been disease--free for more than 2 years. In conclusion, the placement of a self-expandable metallic stent in combination with cholangioscopic microwave coagulation therapy and TS-1 was very effective in managing the obstructive jaundice due to the local recurrence of gastric cancer.

12/62. A case report of synchronous double primary liver cancers combined with early gastric cancer.

    Combined hepatocellular carcinoma and cholangiocarcinoma is found at a frequency of 1.0-6.3% in resected primary hepatic tumors. However, the case of double cancers of hepatocellular carcinoma and cholangiocarcinoma that are discovered synchronously in different lobes of a liver is very rare. We experienced a case of a 74-year-old man who was found to have hepatocellular carcinoma and cholangiocarcinoma in different lobes of the liver, which were accompanied by early gastric cancer. To our knowledge, this is the first case report of double primary hepatic cancers accompanied with early gastric cancer. The pathogenesis and previous related reports of these lesions are discussed.

13/62. Primary Hodgkin's disease of the stomach. A case report.

    Primary gastric Hodgkin's disease is rare and has been reported in only 2% of patients with primary gastric lymphomas. Its existence is quite controversial, and new immunohistochemical techniques and flow cytometry have reduced the frequency of diagnosis of this pathology. The authors describe a case of primary gastric Hodgkin's disease in a 61-year-old woman.

14/62. Diffuse pulmonary infiltrates in hypogammaglobulinemia.

    This is the first case report of lymphangitic carcinomatosis from adenocarcinoma of the stomach presenting as interstitial lung disease in a patient with CVH. adenocarcinoma of the stomach occurs with increased frequency and at an earlier age in CVH as compared with the normal population. This diagnosis should be kept in mind during evaluation of patients with CVH. Periodic examinations of stool for occult blood should be performed. Aggressive diagnostic evaluation should be undertaken in any CVH patient with gastric complaints, as well as careful follow-up in patients with pernicious anemia, atrophic gastritis, or achlorhydria with regard to cancer screening.

15/62. Clinical implications of alpha-fetoprotein expression in gastric adenocarcinoma.

    BACKGROUND: Alpha-fetoprotein (AFP)-producing gastric adenocarcinoma has an extremely poor prognosis. Few cases have been reported in germany until now. Here we report on a patient with an AFP-producing gastric cancer and a subsequent analysis of AFP expression in a more extended series of gastric cancer patients. MATERIAL AND methods: A 62-year-old man was referred to our hospital with suspected gastric cancer. gastroscopy, ultrasound, and CT scans of the abdomen showed a gastric tumour. Serological and histopathological investigations led to the diagnosis of a poorly differentiated adenocarcinoma expressing AFP. Following diagnosis, a short-term response was achieved by palliative chemotherapy. Expression of AFP and albumin was then investigated on an extended series of 25 patients with gastric cancer and four gastric cancer cell lines using immunohistochemistry and RT-PCR. No patient had suffered from hepatocellular carcinoma or germ cell tumor. RESULTS: Using paraffin-embedded gastric cancer specimens, we found AFP immunohistochemically in 2 of 25 (8%) patients. AFP-mRNA was expressed in 3 (12%) patients and a single gastric cancer cell line (AGS). Albumin-mRNA was not found in any gastric cancer sample or gastric cancer cell line. CONCLUSIONS: Our study shows that AFP-producing gastric adenocarcinomas are an important clinical entity with a frequency that has been underestimated in the past. In the absence of a primary liver tumor, clinicians have to consider a primary gastric cancer, which has a poor prognosis, and merits a more aggressive therapy.

16/62. Gastric neuroendocrine carcinoma arising from heterotopic pancreatic tissue.

    An 85 year old man presented with symptoms of dyspepsia and increase in stool frequency of two months duration. Upper endoscopy revealed an ulcer and the biopsy was interpreted as carcinoma with endocrine features. A formal distal gastrectomy was planned, but intraoperatively, because of the patient's condition, a wedge resection was performed. histology revealed a neuroendocrine tumour (grade 1), located mainly in the submucosa, which had caused mucosal attenuation and ulceration. Associated with the tumour and at its periphery was heterotopic pancreatic tissue composed of acini, ducts, and endocrine cells. The tumour was strongly positive for chromogranin and focally for synaptophysin. There was no associated chronic atrophic gastritis or G cell hyperplasia. A discrete focus of high grade neuroendocrine carcinoma (grade 3) within the typical (grade 1) neuroendocrine tumour was also present. This case illustrates a grade 1 neuroendocrine carcinoma, with a small grade 3 focus, arising within or intimately associated with heterotopic pancreatic tissue in the stomach. Although the two entities may be separate, their close topographical association favours the possibility of neuroendocrine carcinoma arising from the heterotopic pancreas. Pathologists should be aware of the occurrence of pancreatic heterotopia in the stomach and the association of carcinoma with it.

17/62. Ultrasound-guided radiofrequency ablation: a new treatment option after failure to stop severe acute upper gastrointestinal tumor bleeding using endoscopic techniques.

    endoscopy is well established as the primary approach in cases of severe acute upper gastrointestinal bleeding. Although endoscopic techniques can achieve hemostasis in up to 95% of instances, not all sources of bleeding seen at endoscopy can be managed endoscopically. Massive and diffuse bleeding from locally advanced gastric adenocarcinoma is not usually self-limit-ing and is often refractory to endoscopic treatment. If surgery or endovascular tumor embolization are not possible after failure of endoscopic hemostasis, the situation may become life-threaten-ing. We present a new option for the treatment of patients in this rare but potentially fatal situation, which involves radiofrequency ablation using a needle electrode placed percutaneously un-der ultrasound guidance.

18/62. liver metastases of a minute rectal carcinoid less than 5mm in diameter: a case report.

    We report a case of liver metastases of a minute rectal carcinoid less than 5mm in diameter, which was found during the postoperative follow-up course of a stomach cancer patient. For the early stomach cancer, laparoscope-assisted distal gastrectomy with lymph node dissection was performed on August 26, 1998. Later, abdominal CT revealed space-occupying lesions in the liver (S2). Metastatic tumors of the stomach cancer were suspected, but further examination revealed that the lesions were metastatic tumors due to a rectal carcinoid tumor. Ten months later, metastatic carcinoid tumors were found in the liver (S1, S5, S6, S7, S8). Subsegmentectomy of the liver (S7) and microwave coagulation therapy (S1, S5, S6, S8) were performed. Carcinoid tumors metastatic to the lymph nodes, liver, and other areas have been reported, but all were larger than 20mm in diameter. In this case, the primary tumor was less than 5mm in diameter, which is extremely rare. This patient was successfully treated with lateral segmentectomy, subsegmentectomy (S7), microwave coagulation therapy of the liver, and transanal extirpation. She is presently in a good condition and has had no recurrence of the carcinoid tumor from ten months after the last hepatectomy.

19/62. Treatment of recurrent malignant obstruction with a flexible covered metal stent after gastric surgery.

    BACKGROUND: The management of gastric outlet obstruction with expandable metallic stents is difficult and frequently is associated with late complications. A new, flexible, covered metal stent has been developed, which may be suitable for treatment of patients with recurrent malignant strictures after gastric surgery. methods: The stainless-steel stent is covered by a polyethylene membrane. It has a proximal funnel attached to an expanded antimigratory segment 29 mm in diameter. The flexible covering membrane connects isolated distal segments that are 20 mm in diameter. The stent is preloaded in a 6.7-mm-diameter introducer system. The structural features and the increased flexibility of this new prosthesis are intended to reduce the risk of migration and the frequency of late complications, and to broaden the range of applications. RESULTS: This stent was used to successfully treat two patients with recurrent tortuous malignant strictures after partial or complete gastrectomy. CONCLUSIONS: This new flexible, polyethylene-covered stent potentially is a new alternative for the palliation of patients with recurrent, inoperable gastric malignant strictures.

20/62. Bilateral adrenal enlargement and non-suppressible hypercortisolism as a presenting feature of gastric cancer.

    In patients with cancer, adrenal enlargement due to either metastatic disease or diffuse non-metastatic hyperplasia is increasingly recognized with modern imaging techniques. Dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, characterized by non-suppressible hypercortisolism, has also been described in neoplasia in the absence of ectopic adrenocorticotrophic hormone (ACTH) production. In the majority of cases of malignancy-associated hypercortisolism, it might be expected that the presence of malignant disease would be clinically apparent, thus rendering a detailed endocrinological evaluation of the HPA axis unnecessary. However, in the present case we describe a patient with occult malignancy presenting with bilateral adrenocortical enlargement and non-suppressible hypercortisolism that was not due to the ectopic ACTH syndrome. There were no clinical Cushingoid features other than hypertension and new-onset diabetes mellitus. Detailed diagnostic investigations for the possibility of Cushing's syndrome were performed before the underlying diagnosis of gastric adenocarcinoma eventually became apparent. Characteristics and potential mechanisms of non-suppressible hypercortisolism in cancer are discussed. We believe that this scenario will occur with greater frequency in the future, given the increasing early use of sophisticated high-resolution imaging for the evaluation of suspected intra-abdominal pathology.
