BACKGROUND The rise in adenocarcinoma (AC) of the esophagus has been reported in several papers. However, the results are only comparable to a limited extent, because they are based on differing periods and different computational methods. The purpose of the current investigation was to collect the available data and to analyze them in a unified manner. (More)
The prognostic role of epidermal growth factor receptor (EGFR) and HER2-neu remains controversial in patients with non-small cell lung cancer (NSCLC). We studied the association between the mRNA expression of EGFR, HER2-neu, and survival in primary tumor and matching nonmalignant tissues from 83 patients with NSCLC. Analysis was performed using a(More)
AIMS The significance of MUC1, MUC2 and sialylated Lewis blood group antigens as prognostic markers in colorectal adenocarcinoma was investigated in a large series of patients because previous investigations revealed inconsistent results due to unrelated tumour samples from different patient groups and methodological differences. METHODS AND RESULTS(More)
BACKGROUND The main purpose of this study was to determine prognostic factors in patients with surgical treatment of adenocarcinoma of the esophagus. METHODS Within a 12.5-year period, esophageal adenocarcinoma was resected in 165 patients by radical transhiatal esophagectomy (n = 134) or transthoracic en bloc esophagectomy (n = 31). Tumors were analyzed(More)
BACKGROUND The purpose of this study was to compare the prognosis of patients with T1 squamous cell carcinoma (SCC) with those with T1 adenocarcinoma of the esophagus and to explain prognostic differences by an analysis of clinicopathologic characteristics. METHODS Seventy-seven patients with early esophageal cancer who underwent esophagectomy and(More)
OBJECTIVE Transhiatal esophagectomy (THE), mostly performed in patients with adenocarcinoma of the esophagus, bears the risk of damage to mediastinal structures because the physician's vision is poor during esophageal dissection. The authors report a new endoscopic technique, which enables microsurgical dissection of the esophagus under visual control, that(More)
BACKGROUND The outcome after oesophagectomy depends not only on the surgical procedure itself but can be improved by the selection of patients based on a preoperative risk score. METHODS In order to compare the preoperative risk for different histological subtypes of oesophageal carcinoma, 221 patients with a squamous cell carcinoma (SCC) and 104 patients(More)
BACKGROUND AND OBJECTIVES The indication for splenectomy in proximal gastric cancer remains controversial. Splenectomy is performed because of possible lymph node metastasis of the splenic hilus or infiltration/metastasis of the spleen. The purpose of this study was to investigate the frequency of lymph node metastasis to the splenic hilus and metastasis to(More)
AIMS One important step in tumour invasion is the penetration of the basement membrane. Matrix metalloproteinases (MMPs) play a key role in the migration of normal and malignant cells through the basement membrane. The aim of this study was to investigate correlations between matrix metalloproteinase 2 (MMP-2) immunoreactivity and currently used(More)
