Abstract:
Benefits of local therapy for liver oligometastases of esophageal cancer has not been established. There are 2 cases of resection for liver oligometastases of esophageal cancer. Case 1: A 65-year-old male diagnosed with liver metastasis of esophageal cancer 12 months after initial treatment. A tumor located in segment 7 was resected after 6 months of chemotherapy. Case 2: A 71-year-old female diagnosed with liver metastasis of esophageal cancer 14 months after initial treatment. During 6 months of chemotherapy, tumor diameter increased but there were no new lesions. The tumor located in segment 8 was resected. In both cases, R0 resection was performed without intraoperative injury to the reconstructed esophagus. They had a recurrence free survival of more than 5 months. Resection of liver metastasis of esophageal cancer may be useful in combination with drug therapy in case it was diagnosed with liver oligometastases.
