[A Case Report of R0 Resection after Chemotherapy for Locally Advanced Pancreatic Head Cancer with Ureter Invasion]

A 60-year-old woman was referred to our hospital due to pancreatic head cancer with right ureter invasion. We considered that it was difficult to achieve R0 resection for the patient by operation because of a wide range of retroperitoneal invasions involving the right ureter. She was treated with chemotherapy(gemcitabine plus nab-paclitaxel: GnP). GnP therapy was administered 3-weeks on/1-week off for 1 course. After 3 courses, we performed pancreaticoduodenectomy, right nephrectomy and partial transverse colectomy. We achieved R0 resection and considered the GnP therapy to be effective.
