Slide 1-

Pancreatic Cancer: Case and Discussion Andrew D. Rhim, MD University of Michigan Medical School
Slide 2-

Clinical Case 72yo man presents to General GI clinic for abdominal discomfort after eating Developed over the past 8-9 months Vague, dull discomfort/pressure starting 10-20 minutes after eating and lasting for 30min to a few hours Does not interfere with daily activities (2-3/10) Located in the epigastrum, MAYBE radiating to his back Not eating helps, though he has been careful to maintain caloric intake
Slide 3-

HPI 72yo man presents to General GI clinic for abdominal discomfort after eating No associated nausea, vomiting, diarrhea or constipation Has noted 20lb weight loss in the past 2-3 months, though he denies anorexia Denies new-onset depression, jaundice, malaise Has noted increased urination and thirst (maybe)

Why? High suspicion for neoplasm HPI: Vague, dull discomfort/pressure starting 10-20 minutes after eating and lasting for 30min to a few hours Located in the epigastrum, MAYBE radiating to his back Has noted 20lb weight loss in the past 2-3 months, though he denies anorexia Denies new-onset depression, jaundice, malaise Has noted increased urination and thirst
Slide 15-

Why? High suspicion for neoplasm PMH Diabetes mellitus II Diagnosed 6 months ago Recent requirement of insulin 2 weeks ago Labs: Fasting glucose elevated CT pancreas: Abrupt cut-off of pancreatic duct Atrophy of distal pancreas
Slide 16-

Mass in body of pancreas Diagnosis: Pancreatic ductal adenocarcinoma, Stage 1 Treatment: Surgical resection + Adjuvant chemo

Pancreatic Cancer Epidemiology Incidence: 11.7 per 100,000 Rising incidence 6.7% increase 19952005 Lifetime risk: 1.41% 1 in 71 Americans will be diagnosed w/ PC Median age of diagnosis: 72 Median age of death: 73 SEER, 2009

Slide 19-

Pancreatic Cancer: Poor survival due to metastatic disease 5 year survival from diagnosis: <5% (all-comers) 80% will present with invasive and metastatic disease at diagnosis Even with chemotherapy, median survival is ~6mo 20% will present with limited primary tumors with no metastatic disease Most of these patients will undergo surgical resection
Slide 20-

Surgical Treatment Only chance at cure Only indicated for patients with: Limited tumor burden No evidence of mets Satisfactory surgical risk Whipple procedure v. distal Relatively high morbidity Post-op infection, leaks, bleeding Brittle diabetes Malnutrition and weight loss Adjuvant chemtherapy recommended
Slide 21-

Poor survival even after surgery Even without clinical evidence of metastasis, 5y survival after resection is poor (~20%) Even with small tumors Mostly due to metastatic disease Agarwal et al., Pancreas 2008
Slide 22-

Early warning signs of PDAC Abrupt onset of diabetes in non-obese individuals over the age of 60 OR sudden insulin requirements or erratic blood sugar control Depression Evidence of pancreatic exocrine insufficiency Foul smelling, floating stools Malabsorption Weight loss despite sufficient caloric intake Non-specific symptoms: Malaise, weight loss, anorexia, dull abdominal discomfort Diagnostic test: pancreas protocol CT scan + IV contrast (though MR may be better)
Slide 23-

High risk groups Chronic pancreatitis Especially hereditary pancreatitis Familial pancreatic cancer ≥2 first degree relatives with PDAC Other genetic syndromes Familial Atypical Multiple Mole Melanoma Syndrome (FAMMM; 38-fold increased risk) Peutz-Jeghers Syndrome (36% lifetime risk) BRCA 2 mutation Cystic fibrosis? Screening: alternating annual EUS + MRI/CT
Slide 24-

Conclusions Pancreatic cancer is a horrible disease Median survival of 6-8mo Will soon be the second leading cause of cancer-related deaths in the US While not perfect, there are “early” warning signs Abrupt onset diabetes, weight loss, depression Surgery is the only treatment that may lead to durable cure at this point in time (~20% live to 5y)
