Pancreatic cancer
By AKASH SINGH
413
Where is the pancreas?
Liver
Stomach
Small
Intestine Pancreatic
Duct
• Between the
stomach and
spine
・ Lies partially
behind the stomach
and rests in the
curve of the small
intestine
http: //www.webmd.com/digestive-disorders/picture-of-the-
pancreas
Statistics
The ACS estimates:
• About 45,220 people (22,740 men and 22,480 women) will be diagnosed
with pancreatic cancer
• About 38,460 people (19,480 men and 18,980 women) will die of pancreatic
cancer
• Rates of pancreatic cancer have been slowly increasing over the past 10
years
• The lifetime risk of developing pancreatic cancer is about 1 in 78.
Exocrine tumors
• Most common type
々 Benign cysts and benign tumors (cystadenomas) can occur, but
most are malignant.
• About 95% are adenocarcinomas
• Less common types include:
々 Adenosquamous carcinomas
< Squamous cell carcinomas
Signet ring cell carcinomas 々 Undifferentiated carcinomas
々 Undifferentiated carcinomas with giant cells
々 Solid pseudopapillary neoplasms of the pancreas 々 Ampullary
cancer (or carcinoma of the ampulla of Vater)
Endocrine tumors
• Known as pancreatic neuroendocrine tumors (NETs), or islet cell
tumors
• Subtypes include:
♦ Insulinomas**
♦ Gastrinomas**
♦ Glucagonomas
♦ Somatostatinomas
♦ VIPomas (Vasoactive Intestinal Peptide)
♦ Ppomas (Pancreatic Polypeptide)
♦ Carcinoid tumors
Risk factors
• Age
• Gender
• Race
• Tobacco use
• Obesity
• Diabetes
• Chronic pancreatitis
• Occupational exposure
• Stomach problems
• Diet
• Coffee
• Alcohol
・ Cirrhosis of the liver
Risk factors
Family history/Genetic syndromes
• Inherited gene mutations may cause as many as 10% of pancreatic cancers:
々 Hereditary breast and ovarian cancer syndrome
♦ Familial melanoma
々 Familial pancreatitis
々 Hereditary non-polyposis colorectal cancer (HNPCC), also known as
Lynch syndrome.
♦ Peutz-Jeghers syndrome (PJS), also linked with polyps in the digestive
tract and several other cancers
♦ Von Hippel-Lindau syndrome
♦ Pancreatic neuroendocrine tumors and cancers can also be caused by a
genetic syndrome, such as: Neurofibromatosis type 1 and Multiple
endocrine neoplasia type 1
Signs and symptoms
• Exocrine tumors
♦ Jaundice
♦ Darkening urine
♦ Abdominal or back pain
♦ Weight loss and poor appetite
♦ Digestive problems
々 Gallbladder enlargement
♦ Blood cots or fatty tissue
abnormalities
♦ Diabetes
• Endocrine tumors
々 Stomach ulcers, abdominal
pain, nausea
♦ Decreased appetite, weight loss,
malnutrition, digestion problems
♦ Diabetes
♦ Diarrhea, gallbladder issues,
jaundice, dark urine
々 Fainting, coma, seizures 々
Rapid heart rate, weakness,
shortness of breath, confusion,
sweating
Signs and symptoms
• Because of the pancreas' deep location, tumors are rarely
palpable through the abdomen.
• Many symptoms of pancreatic cancer often do not appear
until the tumor grows large enough to interfere with the
function of nearby structures:
Stomach
♦ Duodenum
♦ Liver
々 Gallbladder
Laparoscopy
Diagnostic tests
• CT scan
々 CT-guided needle biopsy
• MRI
• Somatostatin receptor scintigraphy
々 Used for diagnosing NETs
• Positron emission tomography
(PET)scan
々 Used to look at spread from
exocrine tumors
• Ultrasonography
々 Endoscopic ultrasound
• X-ray
• Endoscopic retrograde
cholangiopancreatography (ERCP)
• Percutaneous transhepatic
cholangiography (PTC)
• Angiography
• Blood tests
々 Used for diagnosing NETs
• Biopsy
Grading
• Pancreatic cancer does not use a specific grading system,
so it follows the general system:
♦ GX: Undetermined grade
♦ Gl: Well differentiated or low grade
♦ G2: Moderately differentiated or intermediate grade
♦ G3: Poorly differentiated or high grade
♦ G4: Undifferentiated or high grade
Staging
・ Stage 0
・ Stage I
♦ IA
♦ IB
・ Stage II
♦ IIA
♦ IIB
・ Stage
III
・ Stage
IV
Stage I
Stage IA Pancreatic Cancer
Stage IB Pancreatic Cancer
Stage II
Stage IIA Pancreatic Cancer
ile duct—
Duodenum
Stage IIB Pancreatic Cancer
Bile duct
Pancreatic
duct
Duodenum
Cancer in lymph nodes
Stage III
Bile duct—
Pancreatic
duct
Portal
Duodenum
Common hepatic
axis
Pancreas
Cancer
mesenteric
Stage IV
Cancer
Lymph nodes
Cancer in the
pancreas
Pancreatic cancer has
spread to other parts of
the body:
Lung
Liver
Peritoneal cavity
Other terms
• Another factor in staging pancreatic cancers is the extent of
resection:
♦ From RO, where all visible and microscopic tumor was removed...
♦ To R2, where some visible tumor could not be removed
• Some doctors use a simpler staging system, dividing
cancers into groups based on likelihood of surgical removal:
♦ Resectable
♦ Locally advanced (or unresectable)
< Metastatic
Treatment options
• Surgery
• Palliative surgery
• Radiation
• Chemotherapy
• Biologic therapy
• Ablative techniques
