Summary
A rare case of metastatic renal cell carcinoma in a transplanted kidney was identified as originating from the male donor. Tumor resection and immunotherapy led to the resolution of metastases.
Area of Science:
- Nephrology
- Oncology
- Transplantation immunology
Background:
- Renal cell carcinoma (RCC) is a significant malignancy.
- Kidney transplantation is a life-saving procedure for end-stage renal disease.
- Donor-derived malignancies in transplant recipients are exceedingly rare.
Observation:
- A patient developed metastatic renal cell carcinoma 6 years post-cadaveric kidney transplantation.
- Molecular analysis confirmed the tumor originated from the male donor.
- The patient presented with bone and lymph node metastases.
Findings:
- The metastatic renal cell carcinoma was confirmed to be donor-derived.
- Surgical resection of the primary tumor was performed.
- Immunotherapy with alpha-interferon and interleukin-2 was administered after tumor resection and cessation of standard immunosuppression.
Implications:
- This case highlights the potential for donor-to-recipient malignancy transmission.
- Successful treatment involved a multimodal approach including surgery and targeted immunotherapy.
- Understanding donor-derived cancers is crucial for improving long-term transplant outcomes.
