[A Case Report of Long Survival in Pancreatic Cancer with Superior Mesenteric Arterial Invasion Following Multimodal Therapy].

The prognosis of pancreatic cancer with superior mesenteric arterial invasion is very poor and judgment of surgical indication is very difficult. We report a case that received multimodal therapy for pancreatic cancer with superior mesenteric arterial invasion. A 43-year-old woman consulted a local doctor because of upper abdominal pain. Ultrasonography revealed a nodule in the pancreatic body and elevated CA19-9 values. She was referred to our hospital for evaluation and therapy. Computed tomography showed a low-density area in the pancreatic body and around the superior mesenteric artery. The clinical diagnosis was pancreatic cancer with superior mesenteric arterial invasion. She received chemoradiation therapy(RT, 50.4 Gy, gemcitabine[GEM]plus TS-1)followed by distal pancreatectomy. She received adjuvant chemotherapy(TS-1)for 6 months. However, follow-up CTperformed 10 months after surgery revealed local recurrence. The patient received chemotherapy( GEM)for 8 months and GEM plus nab-PTX for 22 months. She died from the cancer 50 months after the primary operation.
