25. The significance of c-erb B-2 and p53 immunoreactivity in patients with adenocarcinoma of the esophagus.
OBJECTIVE: Studies in breast cancer suggest that p53 and c-erb B2 protein overexpression are predictive of outcome. The authors determined whether these molecular markers correlated with treatment response and survival in patients with adenocarcinoma of the esophagus and esophagogastric junction. METHOD: Immunostaining for p53 and c-erb B2 was performed on p

26. Treatment of Barrett's esophagus by endoscopic laser ablation and antireflux surgery.
OBJECTIVE: The regeneration of intestinal metaplasia by squamous epithelium in 17 patients with Barrett's esophagus after endoscopic laser ablation in a reflux-free environment after successful antireflux surgery was prospectively examined. METHODS: All patients had antireflux surgery, and healing of reflux was verified at postoperative endoscopy and 24-hour

27. Epidermal growth factor A61G gene polymorphism, gastroesophageal reflux disease and esophageal adenocarcinoma risk
Background: Single-nucleotide polymorphisms of key cancer genes, such as EGF A61G, are associated with an elevated risk of esophageal adenocarcinoma (EAC). As gastroesophageal reflux disease (GERD) is an established risk factor for EAC, we evaluated whether the association between epidermal growth factor (EGF) polymorphism and EAC development is altered by t

28. Transcriptional control of viral gene therapy by cisplatin
Ionizing radiation (IR) and radical oxygen intermediates (ROIs) activate the early growth response-1 (Egr1) promoter through specific cis-acting sequences termed CArG elements. Ad.Egr.TNF.11D, a replication-deficient adenoviral vector containing CArG elements cloned upstream of the cDNA for human recombinant TNF-α was used to treat human esophageal adenocar

29. Matrix metalloproteinase 1, 3 and 12 polymorphisms and esophageal adenocarcinoma risk and prognosis
The matrix metalloproteinase (MMP) family degrade extracellular matrix and mediate pathways including apoptosis, angiogenesis and immunity. We studied the association between four MMP polymorphisms within three MMP genes and esophageal adenocarcinoma (EA) risk and prognosis. A total of 313 EA cases and 455 age and gender frequency-matched controls were genot

30. Barrett's esophagus. The significance of p53 in clinical practice.
OBJECTIVE: The authors provide an updated review the molecular biology of the p53 tumor suppressor gene with reference to its role in the malignant degeneration of Barrett's esophagus. SUMMARY BACKGROUND DATA: Appreciation of the function of the tumor suppressor gene p53 has given new insight into regulation of the cell cycle, and the gene appears to play an

31. Downstaging of esophageal cancer after preoperative radiation and chemotherapy.
OBJECTIVE: This retrospective, nonrandomized review evaluates 125 patients with esophageal carcinoma (adenocarcinoma and squamous cell) who underwent either surgery only or preoperative chemotherapy and/or radiation therapy followed by surgery. Major end points were survival and postchemoradiation downstaging. METHODS: Forty-four patients underwent radiation
