| Outline of Final Research Achievements |
For the intraoperative diagnosis of lymph-node micro-metastases with immunohistochemical staining, the staining time should be shortened. We invented a new method that allows to reduce the immunohistochemical-staining time by applying an electric field to the tissue sections. We can complete immunohistochemical staining which usually requires 2 hours, within 12 minutes using this method. We demonstrated that this method was useful for the intraoperative detection of lymph node micrometastases of patients with lung cancer. We also demonstrated that this method is useful for the grading of the glioma during surgery. We tried this method to the decision making of the surgery for lung cancer and brain tumor. We also tried this method to the decision making of the surgery of gastroenterological, gynecologic, pediatric cancer and cancer of otorhinolaryngology. And then, we were able to demonstrate the usefulness of this method for the decision making of these surgeries
