[A Case of Long-Term Survival in a Patient with Colorectal Liver Metastasis Treated with Multidisciplinary Therapy]

A-71-year-old man underwent right hemicolectomy combined with partial resection of the small intestine and duodenum for an ascending colon carcinoma in July 2009. He presented with a liver metastasis adjacent to the inferior vena cava in November 2009. He received 6 courses of FOLFOX4, but the therapeutic effect was SD, so he underwent an extended posterior sectionectomy combined with partial S8 resection, inferior vena cava resection, and cholecystectomy. He developed remnant liver recurrence in February 2011 and another partial S8 resection was performed. He presented with remnant liver recurrence in October 2011, and radiofrequency ablation and systemic chemotherapy were performed, but were not effective. In June 2013, we performed an extended S8 segmentectomy combined with median hepatic vein and diaphragm resection. He is alive 2 years after the third hepatectomy without any recurrence. Although non-anatomical resection is often performed in repeat liver resections for colorectal liver metastases, sometimes detection of recurrent lesions in the same segment indicates Glisson invasion; therefore, anatomic resection may prolong long-term survival.
