Combined treatment with by-pass operation, irradiation and immunochemotherapy for advanced thoracic esophageal cancer.

Based on the experimental results that operative stress of thoracotomy or laparothoracotomy has enhanced tumor growth remarkably in rats compared with laparotomy, a new combined treatment with by-pass operation, irradiation and immunochemotherapy was investigated in 39 advanced thoracic esophageal cancer patients. At by-pass operation, abdominal esophagus was divided and its proximal stump was closed immediately. Cervical esophagus was then divided and its distal stump was pulled out to the right supraclavicular region to make outer fistula. Thus, anticancer drug was poured into the esophagus through outer fistula very easily just before irradiation and then irradiation was performed under the condition that the lesion was immersed in the drugs. As anticancer agent, Mitomycin-C, 5-Fluorouracil or Bleomycin was given alternately. Lately, the combination of 5-Fluorouracil and Vitamin A was preferably used. The changes of immunological parameters and the survival after the onset of treatment was reported.
