Abstract
Purpose
Renal injury is common in cancer patients and its etiology is multifactorial. Different patterns of renal histological lesions have been described in relation to oncologic treatments, notably acute tubular necrosis and tubulointerstitial nephritis, but also thrombotic microangiopathy (TMA).
Methods
We report a case of TMA secondary to capecitabine in an 82-year-old woman diagnosed with localized colon adenocarcinoma.
Results
The patient, with previous normal kidney function, presented with renal impairment during the fourth cycle of chemotherapy. After potential nephrotoxic factors were ruled out, capecitabine was discontinued and a kidney biopsy was performed, which displayed TMA lesions. An improvement in renal function was observed after definitive cessation of cytotoxic chemotherapy. Although rare, renal toxicity in the form of TMA may be associated with the use of cytotoxic agents such as gemcitabine, but there is no reported evidence of its association to capecitabine. Early withdrawal of the drug and nephrology consultation is necessary to prevent irreversible damage.
Conclusion
We describe, to our knowledge, the first case reported in the literature regarding the possible association of TMA and capecitabine.
