Chemotherapy in patient with colon cancer after renal transplantation: A case report with literature review.

RATIONALE

Experience of pharmacotherapy in posttransplantation colorectal cancer (CRC) patients is inadequate.

PATIENT CONCERNS

A Chinese man had right renal transplantation and began immunosuppressive treatment at the age of 31 in 2009. He was diagnosed with colon cancer and underwent anterior resection in 2014. He was diagnosed with metastatic colon carcinoma by abdomen computed tomography (CT) and positron emission tomography-computed tomography in April 2017.

DIAGNOSIS

Metastatic colon carcinoma in posttransplantation patient.

INTERVENTIONS

Three cycles of FLOFOX (5-fluorouracil and leucovorin and oxaliplatin) chemotherapy were given since April 2017.

OUTCOMES

Plasma concentrations of immunosuppressant and kidney function were within normal during the chemotherapy. Abdomen CT revealed the progress of colon cancer at the end of the third course of chemotherapy.

LESSONS

A few cases about monochemotherapy of posttransplantation CRC have been reported, whereas experience of doublet chemotherapy was currently unavailable. We shared the experience of FOLFOX in a patient with posttransplantation colon cancer. Neither of incompatibility with immunosuppressant nor serious adverse drug reaction was observed. It provides evidence for the pharmacotherapy of posttransplantation CRC.
