転移性胃癌に対してPaclitaxel/Ramucirumab併用療法中に難治性の間歇的血尿を来たした1例

概要

A 76-year-old male patient developed right hydronephrosis due to peritoneal and retroperitoneal dissemination after surgery for gastric cancer. A ureteral stent was inserted, and systemic chemotherapy was introduced for metastatic gastric cancer. Disease progression was observed, and paclitaxel/ramucirumab combination therapy was started as the second-line treatment. After seven courses, severe gross hematuria appeared intermittently, and refractory epistaxis was observed concurrently. No hemorrhagic lesion was found in the imaging test and urethrocystoscopy. The patient received conservative treatment, such as blood transfusion, and further examination was planned. However, hematuria and epistaxis resolved spontaneously during the course of treatment. From the clinical course, it was thought to be a hemorrhagic adverse event due to ramucirumab, and the patient's treatment was therefore changed to another drug. The patient recovered without recurrence of gross hematuria.
