[A Case of Complete Resection Using the Liver-First Approach after Systemic Chemotherapy in a Patient with Synchronous Colorectal Liver and Lung Metastases].
2021
Conversion surgery for patients with initially unresectable colorectal liver metastases is increasingly being performed because of effective systemic chemotherapy. Additionally, many studies have reported the benefit of the liver-first approach for advanced liver metastasis. We report a case of an initially unresectable advanced colon cancer with multiple liver and lung metastases that was successfully treated with the liver-first approach following chemotherapy. The patient was a 36-year- old woman who was diagnosed with advanced rectal cancer, cT4aN2aM1b, cStage Ⅳb. After a temporary transverse colostomy, she was administered systemic chemotherapy for 9 months. The primary tumor and liver metastases showed partial response while the lung metastases showed complete response. Since it was considered that liver metastases were the main prognostic factors, we performed a right hemihepatectomy plus S3 partial hepatectomy, followed by laparoscopic high anterior resection. A partial pneumonectomy was also performed because of the regrowth of the lung metastases, and we succeeded in complete resection. The liver-first approach was a beneficial treatment option for this patient with unresectable colorectal liver metastases.
