Pancreas adenocarcinoma

Usually arises from the duct
Men more than women, older than 45 years
Generally poor long-term prognosis
No good screening / early detection methods

Pancreas adenocarcinoma: clinical
presentation
• Symptoms occur late in disease course.
• Head of pancreas:
* Jaundice
* Palpable non-tender gallbladder (Courvoisier’s sign)
• Advanced:
* Fat malabsorption: steatorrhea
* Pain
* Fatigue, anorexia, weight loss
Pancreas adenocarcinoma: diagnosis
•

•
•
CT +/- biopsy
MRCP
ERCP & brushing / biopsy
EUS & FNA
Pancreas adenocarcinoma: CT
ERCP:
“Double-duct”
sign
Pancreas malignancy: ERCP
• Sphincterotomy
* Grounding pad, generator, sphincterotome
• Strictures
* Guidewire(s), dilators, stents
* Cytology brush, glass slides, fixative
Pancreas malignancy: EUS
• Fine-needle aspiration & biopsy
• Coordinate with pathologist
• Cytology fixative, glass slides
Pancreas adenocarcinoma: treatment
• Curative resection
• Palliative therapy
“Whipple procedure” =
pancreaticoduodenectomy

•
•
Cystic tumors filled with mucin
Women > men
Body & tail of pancreas
Always considered premalignant / malignant

Women > men
Body & tail of pancreas
Generally benign, but can cause complications
