A 52-year-old woman undergoing right mastectomy followed by adjuvant radiotherapy and hormone therapy soon reported upper abdominal discomfort. Enhanced computed tomography showed a portal vein embolism, and CEA and CA19-9 were elevated. The gastrointestinal tract was examined, and an ascending colon cancer was found in colonoscopy. She was admitted and, based on a diagnosis of ascending colon cancer with portal vein tumor thrombosis, she was treated with FOLFIRI, which reduced the tumor thrombosis and CEA. A year later, however, the primary tumor had grown, necessitating laparoscopic right hemicolectomy, followed by FOLFOX, S-1+irinotecan, and S-1 alone. She remains well with no apparent sign of tumor regrowth or recurrence 30 months after surgery.
