ABSTRACT

A 66-year-old man was postoperatively diagnosed with pT4a, pN2, cM1a(H2), cP0, fStage Ⅳ, RAS wild type rectal cancer. He underwent SOX plus Bmab chemotherapy 4 weeks later. After 9 courses of SOX plus Bmab, he was admitted to the hospital for leg edema and proteinuria(4+). Because of severe proteinuria(14.7 g/day)and low protein(Alb 2.0 g/dL, TP 4.9 g/dL), he was diagnosed with nephrotic syndrome. His general condition improved on stopping chemotherapy and administration of conservative treatment, and he was discharged on day 20 after admission. The proteinuria improved 3 months later. He had been undergoing SOX chemotherapy for 4 months.
