The patient was 55-year-old woman, undergoing Hartmann operation by the sigmoid colon
diverticulum perforation, 2 years later visited our hospital with
abdominal pain. Although lower endoscopy and histological examination could not be performed due to stoma
stenosis, we diagnosed cecal
carcinoma, liver
metastasis, distant
lymph node metastasis from CT and PET-CT, CapeOX plus Bmabtherapy and IRIS plus Bmabtherapy were performed. After that, repeated
intestinal obstruction due to exacerbated stoma
stenosis, metastatic lesion increased in CT examination, furthermore the patient had hope of stoma closure, we decided to resect the primacy
tumor, performed subtotal colonectomy and stoma closure. Pathological diagnosis revealed RAS wild type. After surgery, Pmabplus
CPT-11 therapy was performed and the metastatic lesion was temporarily shrunk but re-exacerbated, the patient died 2 years 2 months after the first treatment started, 7 months after the primary
tumor resection. In the treatment of
colorectal cancer, when metastatic lesion is unresectable,
chemotherapy is often carried out except when the primary
tumor is symptomatic. In our case, although the primary
tumor was asymptomatic, an
intestinal obstruction due to stoma
stenosis was developed and it was necessary to examine whether to use anti-EGFR antibody drugs, therefore we performed operation.
