The overall risk of de novo malignancies in kidney transplant recipients (KTRs) is higher than that in the general population. It is associated with long-lasting exposure to immunosuppressive agents and impaired oncological vigilance due to chronic kidney disease. Colorectal cancer (CRC), frequently diagnosed in an advanced stage, is one of the most common malignancies in this cohort and is associated with poor prognosis. Still, because of the scarcity of data concerning adjuvant chemotherapy in this group, there are no clear guidelines for the specific management of the CRCs in KTRs. We present a patient who lost her transplanted kidney shortly after initiation of adjuvant chemotherapy for colon cancer.
A 36-year-old woman with a medical history of kidney transplantation (2005) because of end-stage kidney disease, secondary to chronic glomerular nephritis, and long-term immunosuppression was diagnosed with locally advanced pT4AN1BM0 (clinical stage III) colon adenocarcinoma G2. After right hemicolectomy, the patient was qualified to receive adjuvant chemotherapy that consisted of oxaliplatin, leucovorin and 5-fluorouracil (FOLFOX-4). The deterioration of kidney graft function after two cycles caused chemotherapy cessation and initiation of hemodialysis therapy after a few months. Shortly after that, the patient started palliative chemotherapy because of cancer recurrence with intraperitoneal spread.
Initiation of adjuvant chemotherapy for colon cancer increases the risk of rapid kidney graft loss driven also by under-immunosuppression.
Core tip: The occurrence of colorectal cancer (CRC) in kidney transplant recipients is higher than that in the general population. Advanced stage CRC is usually associated with poor outcome. Adjuvant chemotherapy may accelerate the graft loss after kidney transplant.
