ABSTRACT
Objective To investigate the feasibility, safety and short-term efficacy of endoscopic implantation of 5-FU Slow-release Particles for advanced gastroenteric tumor. Methods During the endoscopy procedure,slow-releasing 5-FU agents were implanted densely into the tumors and infiltrated area. Forty-five to sixty pieces of agents ( each piece equivalent to 1.67 mg 5-FU)were injected, which containing an average dose of 100 mg 5-FU. Results A total of 13 advanced gastric cancer patients were enrolled into this study. Significant effects were observed in 3 patients and good effects in 8 patients, but 2 cases with no effects. The total effective rate was 84.62%. The endoscopy examination showed that the size of tumors reduced in various degree at 1 - 2months after the implantation. No hemorrhage or perforation was observed. Parameters of hepatorenal function and routine blood test were stable after implantation. Conclusion Endoscopic implantation of 5-FU Slow-release Particles can relieve the symptoms of patients and limit tumor growth in advanced gastroenteric tumor with no marrow and hepatorenal functional impair.
