[A case of pancreatic cancer treated by gemcitabine with sequential radiotherapy].

A 65-year-old man suffering from acute pancreatitis underwent MRI scanning, which revealed a low signal on the T1 and T2 sequences, and hypovascularity in arterial phase in the head of the pancreas. This corresponded to the area showing the absence of the lower common bile duct. FDG-PET was highly suggestive of pancreatic cancer (T4N1M0, Stage IVa) with lymph node metastasis. He was treated with systemic chemotherapy using gemcitabine (GEM) followed by radiotherapy. His symptoms gradually improved with a reduction in size of the primary lesion. The patient has been receiving systemic chemotherapy using S-1 without recurrence.
