Variant 1: 65-year-old woman with no comorbidities presents with jaundice and an ECOG performance status of 1. Pancreas-protocol CT scan reveals a 2.5-cm mass in the pancreatic head with encasement of the celiac artery without evidence for nodal or distant metastasis. Biopsy at the time of metal stent placement revealed adenocarcinoma. Stent normalized the bilirubin and the CA 19-9 was 150. She has no pain.
Variant 2: 80-year-old man presents with severe abdominal pain and an ECOG performance status of 2. CT scan reveals a mass in the body of the pancreas with 360° encasement of the celiac axis and SMA, with evidence of regional lymph node metastasis without other distant metastasis; CA 19-9 is 1000.
Variant 3: 54-year-old healthy woman with an ECOG performance status of 0 presents with vague abdominal pain. CT scan notes a pancreatic head mass with no evidence for metastasis. The tumor abuts the celiac axis, although <180°.
Variant 4: Standard RT details in treating a locally advanced pancreatic cancer.
Variant 5: Chemotherapy details in treating a locally advanced pancreatic cancer.
