[Radical Resection Was Achieved Using a Liver-First Approach for Simultaneous Liver Metastasis from Rectal Cancer-A Case Report].

The patient was a 70s male. A fecal occult blood test showed a positive reaction, and colonoscopy was performed. Under a diagnosis of rectal cancer, he was referred to our hospital. Detailed examination revealed solitary liver metastasis measuring 60 mm and involving the S4 to S1 areas of the liver. A strategy to perform systemic chemotherapy in advance was adopted. Five courses of FOLFOXIRI therapy were conducted, and a partial response(PR)was achieved, suggesting that the tumor is resectable. Extended left/caudal lobectomy was performed. There was no complication, and the patient was discharged. After 4 months, laparoscopic low anterior resection and temporary ileostomy were conducted. According to the TNM staging, the grade was evaluated as ypT2N0. On histological response evaluation, the grade was evaluated as 1a. The stoma was closed. During the 1.5-year follow-up after initial treatment, there has been no relapse. We encountered a patient with simultaneous liver metastasis from rectal cancer in whom the use of a liver-first approach(LFA)after systemic chemotherapy facilitated radical resection. The present case suggested that the LFA contributes to a rise in the resection rate, further improving the prognosis.
