| Outline of Final Research Achievements |
Acetaldehyde is a powerful carcinogen in thoracic esophageal cancer. The aim of this study is to evaluate perioperative change of mouth acetaldehyde and its causal oral bacteria in thoracic esophageal cancer patients under intensive oral care. Analysis was done compared to control cases. Drinking and smoking histories were longer and oral condition was worse in patients group than in control. Acetaldehyde in mouth air of thoracic esophageal cancer patients decreased after oral intensive care before operation. It also decreased after operation. It is suggested that intensive oral care for perioperative thoracic esophageal cancer patients decreases acetaldehyde produced in oral microbiome.
