| Research Abstract |
Biological characteristics and immnologic response of esophageal carcinoma were studied clinically and experimentally. DNA contents of the cancer cell nuclear were measured by flow cytometry. From this study, aneuploid cancer showed significant poor survival as compared to diploid one. But there were no significances in patients with radical operation except early cancers between diploid and aneuploid cancers. Proliferating cancer cells were measured by monoclonal antibody Ki-67. By this result, the cancer with Ki-67 positive cells showed significant poor prognosis as compared to the cancer without Ki-67 positive cells. Monoclonal antibody of KISM-1 which was produced in our Institute showed high affinity to esophageal squamous cell carcinoma, and a low affinity was recognized in stomach and colonic carcinoma.
