Table 1 Clinicopathological summary of 83 gastric adenocarcinomas

From: The development of a mini-array for estimating the disease state of gastric adenocarcinoma by array CGH

For Screening   
The number of gastric cancers examined: 83
   Average age of patients (range): 70 years old (44 – 89 years)
Histological type of gastric cancers   
Intestinal-type: 41
Diffuse-type: 42
  Intestinal-type Diffuse-type
   Average age (years) 72 68
   Sex (F/M) 9/32 12/30
   Node metastasis 26 34
   Liver metastasis 3 3
   Peritoneal dissemination 7 12
   Early/advanced cancers* 6/35 4/38
For validation of the mini-array   
The number of gastric cancers examined: 30  
   Average age of patients (range): 69.3 years old (44 – 88 years)  
   Sex (F/M) 11/19  
   Histological type of gastric cancers   
   Intestinal/diffuse 13/17
   Node metastasis 9
   Liver metastasis 3
   Peritoneal dissemination 5
   Early/advanced cancers* 3/27
  1. *Early gastric cancer is defined as a tumor with invasion limited to mucosa or submucosa according to the Japanese classification of gastric carcinoma (9).
