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

These are tumors that remain and remain unstudied in Mali because they are common in adults in our context. Its annual incidence is estimated at approximately 1/10,000 births. Nephroblastoma is a rare or even exceptional tumor in adults. The clinical manifestation was a large swelling of the right hypochondrium;abdominal pain for a year;unquantified fever, hypertension, initial hematuria associated with burning during urination and anemia. The main clinical manifestation remained fever and abdominal pain. This renal tumor posed a diagnostic problem which was previously labeled as a mesenteric tumor in our general surgery department. The diagnosis was made by imaging: CT and magnetic resonance imaging. The treatment is multidisciplinary and combines chemotherapy, surgery with or without radiotherapy. The prognosis is poor due to late diagnosis and less effectiveness of chemotherapy compared to the child. Survival did not exceed a year and a half because the renal tumor in our patient was surgically overcome. We report a case of nephroblastoma in an 86-year-old patient with unfavorable histology (hematogenous metastases), operated on in the general surgery department and whose postoperative course was simple and who was referred to oncology for treatment.展开更多
