Methods: Conversion to sirolimus (SRL) treatment was performed for 10 cases which had found malignant tumors after kidney transplantation. During the follow-up period, the recurrence and diffusion of the tumor, the renal function and rejection were monitored. Results: All these cases despite the death had been followed up for at least 1 year. 9 cases had no recurrence and diffusion. 1 case died due to the tumor diffusion 7 months after the drug conversion. 1 case suffered once acute rejection 2 months after the drug conversion. This acute rejection had been inhibited by flushing dose MP. Conclusion: As a new immunosuppressant, SRL not only can prevent the generation of AR, but inhibit proliferation and development of malignant tumors in kidney transplantation recipients as well.展开更多
