1. Guidelines for Screening

 

The average lifetime risk of pancreatic cancer is less than 1%

About 90% of pancreatic cancers are sporadic

About 10% of pancreatic cancers are inherited

 

Low risk factors:

Increasing age, especially over age 60

African-Americans

Overweight or obese

Chronic pancreatitis

Incidental cystic lesions of the main or branched pancreatic ducts

Diabetes

Smoking

 

High risk factors:

 

Family history

 

Familial pancreatic cancer is when two or more first-degree relatives (parents, brothers, sisters and children) are diagnosed with pancreatic cancer

 

Families with three or more close relatives (first-degree relatives, grandparents, aunts, uncles, nieces, nephews, grandchildren, cousins) diagnosed with pancreatic cancer, and with one relative diagnosed before age 50, are also considered to have familial pancreatic cancer

 

The National Institutes of Health (NIH) estimates that the risk of developing pancreatic cancer is increased four to five times for a person with one first-degree relative with pancreatic cancer, six to seven times for a person with two first-degree relatives, and 32 times for a person with three first-degree relatives with the disease

 

Nearly one hundred genes have been associated with pancreatic cancer

The clinical conditions which are, or maybe, associated with pancreatic cancer are:

Hereditary pancreatitis (HP)

Peutz-Jeghers syndrome (PJS)

Familial malignant melanoma and pancreatic cancer (FAMM-PC)

Hereditary breast and ovarian cancer (HBOC) syndrome

Lynch Syndrome

Li-Fraumeni syndrome (LFS)

Familial adenomatous polyposis (FAP)

Ataxia Telangiectasia Group D Complementing gene (ATDC)

 

Screening:

 

There is no standard procedure for screening either the general population or individuals with an increased risk of pancreatic cancer. Researchers are studying high resolution computed tomography (CT or CAT) scanning, endoscopic ultrasound and endoscopic retrograde pancreatocholangiography (also called endoscopic retrograde cholangiopancreatography or ERCP) as possible screening methods

Patients with incidentally found on abdominal sonography or CT scan require endoscopic ultrasound and magnetic resonance cholangiopancreatograph

 

Screening is not recommended

 

 

2. Cancer Prevention

 

Controllable risk factors:

Eating a balanced diet

Maintaining a healthy weight

Exercising

Limiting alcoholic beverages

Avoiding tobacco products

     Smoking is the biggest controllable risk factor for pancreatic cancer

     Quitting smoking preferably by joining a smoking cessation program

          Smoking cessation programs:

A new study suggests aspirin may help reduce the risk of pancreatic cancer by approximately 25%
