[A Case of Long-Term Survival by Multidisciplinary Surgical Treatment for Metastatic Multi-Organ Metastasis after Radical Resection of Esophageal Cancer].

A 78-year-old man with advanced thoracic esophageal cancer underwent radical esophagectomy after neoadjuvant chemotherapy with cisplatin plus 5-FU. He had left adrenal metastasis 10 months after surgery and removed it, but 3 months later he had liver metastases. After 2 courses of chemotherapy with nedaplatin plus 5-FU, resection was performed. One course of nedaplatin plus 5-FU for adjuvant chemotherapy was added, but the patient was followed up without another chemotherapy after surgery because of intestinal obstruction due to infection and increase of the lymphatic cyst in the abdominal cavity. Six months after the liver resection, nodules appeared in the right lung, and 4 months later, multiple nodules extending to both lungs were observed. Therefore, it was judged that there were multiple lung metastases, and administration of nivolumab was started. He has been 3 years since the recurrence of esophageal cancer and 17 months after the start of nivolumab administration, but the recurrence lesion is only progressing to lung metastasis.

[Extracorporeal partial nephrectomy and auto-transplantation after presurgical targeted therapy with tyrosine kinase inhibitors for renal cell cancer].

A 74-year-old woman who had previously undergone left nephrectomy because of calculi was referred to our department with a right renal mass that was detected by computed tomography (CT) during treatment for pyelonephritis. Repeated CT showed a contrast-enhanced 4.7 cm tumor close to the renal sinus, and no metastatic lesion was detected. Sunitinib was administered as a presurgical therapy ; however, the patient experienced grade 3 neutropenia and thrombocytopenia, and sunitinib was discontinued. Sorafenib was administered 7 days after discontinuation of sunitinib ; however, the patient experienced febrile neutropenia and rash, and sorafenib was discontinued. Extracorporeal partial nephrectomy and auto-transplantation were performed 24 days after discontinuation of sorafenib. Though peri-graft abscess was suspected to be present and resolved by antibacterial therapy, severe complications were not experienced, and the patient did not require dialysis therapy after surgery. There was no evidence of recurrence at 30 months after the surgery.
