The purpose of this study was to investigate micrometastasis (MM) and tumor cell microinvolvement (TCM) in the regional lymph nodes of patients with esophageal squamous cell carcinoma (SCC). ## METHODS. MM was defined as individual tumor cells or tumor cell clusters Ο½0.5 mm in greatest dimension

## BACKGROUND. In a previous study the authors demonstrated, using immunohistochemical methods for epithelial antigens, that the regional lymph nodes of gastric adenocarcinoma contained individual tumor cells or small clusters of these cells (tumor cell microinvolvement [TCM]) in over 90% of cases
## BACKGROUND. Tumor involvement of regional lymph nodes has a crucial impact on the prognosis of patients with adenocarcinoma of the esophagogastric junction (AEG). Although additional tumor cell deposits can be detected by sensitive methods (e.g., immunohistochemistry and polymerase chain reacti
## Abstract ## BACKGROUND Micrometastases consisting of one to a few cells in lymph nodes resected during gastrectomy are difficult to identify using conventional hematoxylin and eosin (H&E) stains. It has been shown that immunostaining for cytokeratins is effective in detecting lymph node microme
## Abstract The aim of this study was to elucidate what factors affect the survival of patients with advanced gastric carcinoma. The relationship between the survival of 282 patients over a period of 15 years and 12 prognostic factors was investigated. In univariate analysis, lymph node involvement
