Using 5-fluorouracil (5-F U) and mitomycin (M M C), 20 patients with advanced gastric, esophageal, and rectal cancer were treated with endoscopic multi-point injection under direct vision. The results showed that: The tumors were reduced and localized in varying degrees. The clinical symptoms were partly relieved. There was no obvious side effects and no myelosuppression was observed. Endoscopic interventional injection of chemotherapeutic drugs in the tumor is a simple and easy method for palliative treatment of advanced gastrointestinal cancer.
