1/164. Metastatic esophageal carcinoma to the orbit.

    PURPOSE: To report a case of esophageal adenocarcinoma and areas of gastric differentiation in the esophagus (barrett esophagus) metastatic to the orbit. methods: A 47-year-old man with a history of esophageal carcinoma developed turgescence around his left eye. He underwent a biopsy and histologic examination of a left orbital mass. RESULTS: Histopathology of the orbital tumor was consistent with metastatic adenocarcinoma from the esophagus. CONCLUSIONS: This metastatic adenocarcinoma to the orbit likely arose in barrett esophagus.

2/164. Importance of duodeno-gastro-esophageal reflux in the medical outpatient practice.

    BACKGROUND/AIMS: The role of acid and duodeno-gastro-esophageal reflux (DGER), also termed bile reflux, in esophageal mucosal injury is controversial. Several recent developments, especially availability of the recent bilirubin monitoring device (Bilitec), have resulted in clarifications in this area. In order to better understand the role of acid and DGER in esophageal mucosal injury, we summarized the recent publications in this area. METHODOLOGY: review of published medical literature (medline) on the clinical consequence of esophageal exposure to gastric acid or DGER. RESULTS: Recent data suggest that esophageal ph monitoring and pH > 7 is a poor marker for reflux of duodenal contents into the esophagus. DGER in non-acidic environments (i.e., partial gastrectomy patients) may cause symptoms but does not cause esophageal mucosal injury. Acid and duodenal contents usually reflux into the esophagus simultaneously, and may be contributing to the development of Barrett's metaplasia and possibly adenocarcinoma. proton pump inhibitors decrease acid and DGER by reducing intragastric volume available for reflux and raising intragastric pH. The promotility agent cisapride decreases DGER by increasing LES pressure and improving gastric emptying. CONCLUSIONS: 1) The term "alkaline reflux" is a misnormer and should no longer be used in referring to reflux of duodenal contents. 2) Bilitec is the method of choice in detecting DGER and should always be used simultaneously with esophageal pH-monitoring for acid reflux. 3) DGER alone is not injurious to esophageal mucosa, but can result in significant esophageal mucosal injury when combined with acid reflux. 4) Therefore, controlling esophageal exposure to acid reflux by using proton pump inhibitors also eliminates the potentially damaging effect of DGER.

3/164. Rapid progression to high-grade dysplasia in Barrett's esophagus after liver transplantation.

    There is an increased incidence of malignancies in transplant recipients. Accelerated progression from a premalignant lesion to carcinoma has been reported in transplant recipients with skin cancer and colon cancer. Whereas Barrett's esophagus is a common premalignant condition in the normal population, rapid progression to severe dysplasia or carcinoma has not been widely reported in transplant recipients. We report on a liver transplant recipient who developed rapid progression from Barrett's esophagus without dysplasia to high-grade dysplasia within 9 months after transplantation.

4/164. Second primary Barrett's adenocarcinoma after 19 years.

    Because long survival after resection of esophageal carcinoma is uncommon, second esophageal cancers are rare. We report the case of a patient in whom adenocarcinoma developed within residual Barrett's esophagus 19 years after esophagectomy for stage IIb Barrett's adenocarcinoma. Implications relative to the type of operation and adequacy of resection are discussed. Long-term survival after Barrett's adenocarcinoma may occur more often if surveillance protocols achieve their aim. Questions concerning the management of such patients are identified.

5/164. Clonal analysis of a case of multifocal oesophageal (Barrett's) adenocarcinoma by comparative genomic hybridization.

    Oesophageal adenocarcinomas arising in Barrett's epithelium occasionally present as multiple lesions. This could be due to either a multifocal presentation of the same tumour, or different neoplasms arising simultaneously in a dysplastic Barrett's oesophagus ('field cancerization'). This is a report of the genetic analysis of multiple neoplastic sites in a Barrett's oesophagus with an extensive area of dysplasia. In addition, the dysplastic Barrett's epithelium was evaluated. For the genetic screening, comparative genomic hybridization (CGH) allowed evaluation of the whole genome of each specimen. Five cancerous regions were selected and subsequently dissected from paraffin-embedded tissue blocks. The use of archival materials enabled a targeted collection of representative tumour locations. Multiple genetic aberrations were detected by CGH in all cancer sites. Losses on 3p, 4, 7q, 18q, and Y, as well as gains on 8q, 9q, 12p, 13q, 17q, 20p and X, were found in each specimen. In four out of the five lesions, simultaneous losses on 9p, 15q, and 16q, with concomitant gains on 5p, 7q, and 10p, were disclosed by CGH. Adjacent high-grade dysplastic Barrett's mucosa shared the losses on 3p, 4, 7q, 9p, 18, and Y, as well as the gains on 5p, 7q, 13q, 17q, and X, thereby confirming its precursor status. Within this single and rare case of multifocal Barrett's adenocarcinoma, a monoclonal genotype was present. This must have been caused by an extensive outgrowth of a single tumour.

6/164. Recent advances in Barrett's esophagus: short-segment Barrett's esophagus and cardia intestinal metaplasia.

    The recent rapid increase in the incidence of adenocarcinoma of the distal esophagus and the gastric cardia has generated significant interest in the premalignant lesion, Barrett's esophagus. The traditional definition of Barrett's esophagus included the presence of 3 cm or greater of columnar mucosa in the distal esophagus. Studies have clarified that intestinal metaplasia was not only the most common and distinctive type of epithelium detected within the columnar mucosa, but also the one with greatest malignant potential; therefore, Barrett's esophagus has come to be defined by the histological presence of intestinal metaplasia. Previous studies evaluating the association of esophageal adenocarcinoma with Barrett's esophagus have only included patients with traditional or long-segment Barrett's esophagus. However, recent studies have suggested that dysplasia and adenocarcinoma can also be associated with short-segment Barrett's esophagus (SSBE), ie, less than 3 cm of columnar mucosa. Data are also emerging regarding the significance of intestinal metaplasia detected in biopsy specimens obtained immediately below the gastroesophageal junction, ie, from the gastric cardia. However, the premalignant potential of cardia intestinal metaplasia (CIM) is unknown at this time. Although the exact incidence of adenocarcinoma in SSBE is not known, endoscopic surveillance of such patients, although controversial, appears to be prudent at this time. With the currently available information, routine biopsy of a normal-appearing squamocolumnar junction is not advocated. This review critically evaluates and summarizes recent data on SSBE and CIM.

7/164. Local treatment of early cancer in short Barrett's esophagus by means of argon plasma coagulation: initial experience.

    In recent years endoscopically controlled local therapeutic methods, such as photodynamic therapy, mucosectomy, or laser therapy, have been used with a curative aim for the destruction of early esophageal or gastric cancers. We report on our experience of treating histologically proven mucosal cancer in Barrett's esophagus with argon plasma coagulation (APC), in three patients. All the mucosal esophageal cancers, with a mean diameter of 4 mm, were successfully destroyed after one or two treatment sessions. Additionally, in two of the three patients the specialized columnar epithelium was replaced by normal squamous cell epithelium when APC treatment was combined with omeprazole. In the third patient with Barrett's esophagus, a partial squamous cell re-epithelialization was induced. No method-related mortality and morbidity were observed. During the mean follow-up of 24.3 /- 1.1 months (range 23-25 months) one tumor recurrence developed which was successfully treated with photodynamic therapy. In patients with small early Barrett's carcinoma APC might offer an effective, minimally invasive alternative to mucosectomy or photodynamic therapy, as the treatment procedure is less cumbersome and the equipment less expensive.

8/164. Clinicopathological and immunohistochemical study of cancer arising from Barrett's esophagus.

    In japan, Barrett's esophageal cancer is a very rare disease. We examined clinicopathologically and immunohistologically 4 patients with Barrett's esophageal cancer who underwent surgical resection in our department. Barrett's esophageal mucosa was classified into 3 types for detailed observation. Specialized columnar epithelium (SCE) remained on the orifice side of carcinoma, and progression to adenocarcinoma was observed in some dysplastic glands. positive findings were detected on p53 immunohistochemical staining, and the ki-67 labeling index was higher than other types. SCE-type Barrett's esophagus may be a precancerous lesion arising prior to the development of adenocarcinoma.

9/164. Barrett's esophagus and chemotherapy, a case report.

    There have been few reports of Barrett's esophagus associated with chemotherapy in children. We report the case of a 3-year-old patient diagnosed with acute lymphoblastic leukemia who developed Barrett's esophagus after BMF-90 chemotherapeutic regimen. A stricture appeared as a complication of Barrett's metaplasia and Nissen fundoplication was performed. Symptoms improved shortly after surgery and regression of Barrett's esophagus was observed 2 years later. Children treated with antileukemic chemotherapy may develop Barrett's esophagus without previous clinical apparent gastroesophageal reflux. Endoscopic surveillance has been advised in these patients. Barrett's esophagus may regress after antireflux surgery.

10/164. Alpha-fetoprotein producing Barrett's esophageal adenocarcinoma: a case report.

    A 59-year-old man was admitted to our hospital with upper abdominal pain. His serum alpha-fetoprotein (AFP) level was very high, 1500 ng/ml. Upper gastrointestinal endoscopy revealed depressed lesion at 36 cm from the upper incisors, with columnar epithelium lining the esophagus circumferentially to the oral side of the lesion. Histological examination of biopsy specimens revealed a tubular adenocarcinoma as well as the presence of gastric columnar epithelium with intestinal metaplasia. immunohistochemistry demonstrated AFP in the tumor cells. From these results, a diagnosis of AFP-producing esophageal adenocarcinoma occurring in Barrett's esophagus, a condition which is extremely rare in japan, was established. Computed tomography (CT) showed multiple metastasis on the liver and wide-ranging lymph node metastasis. Chemotherapy was not effective and the patient died about 2 months after the start of treatment. The AFP-producing esophageal adenocarcinoma presented here had biological characteristics similar to those of AFP-producing gastric cancer.
