Pancreatic cancer is one of the most serious of all cancers. It develops when malignant cells form in the tissues of the pancreas — a large organ that lies horizontally behind the lower part of the stomach. In the United States, approximately 30,000 people die of pancreatic cancer each year, and only 5 percent of patients will survive more than 5 years. Men and women who are overweight or obese are more likely to develop pancreatic cancer than those who are thin.
Function of the Pancreas
The pancreas secretes pancreatic
enzymes that aid
digestion and hormones that help regulate the metabolism of
carbohydrates.
Pancreatic Disease
Several types of pancreatic diseases exist, including:
Diabetes mellitus -
Death from pancreatic carcinoma occurs in
0.2-1.9% of all diabetic patients, being more than 300 times frequent
compared to general population. Diabetes may be the only clinical sign of
pancreatic carcinoma in some patients.
Pancreatitis,
acute and chronic
Pancreatic enzyme deficiency
Pancreatic tumor or cancer
Pancreatic cyst
Risk of Pancreatic Cancer -
Diet and Pancreatic
cancer
Physical activity decreases risk of pancreatic cancer,
obesity increases risk. A diet high in
vegetables reduces the risk of pancreatic cancer. High consumption of sugar and
high-sugar foods are associated with a greater risk of pancreatic cancer.
Additional research suggests eating more whole grain and fiber-rich food
lowers the risk of pancreatic cancer.
Flavonols are common in plant-based foods but are found in highest
concentrations in onions, apples, berries, kale and broccoli. People who
eat the largest amounts of flavonolds have reduced risk of developing
pancreatic cancer.
Supplements for Pancreatic Cancer
Folic acid in
food may reduce the risk for pancreatic cancer, but it is not clear whether a
folic acid supplements would have such benefit. Increased levels of dietary
folate from food appears to reduce the risk of developing pancreatic cancer,
according to results of a large population-based study of Swedish men and women.
Previous studies have suggested that folate may protect against colorectal and
breast cancer. Folate, also known as folic acid, is a B vitamin that is
naturally found in fruits and vegetables. The US government has mandated that
manufacturers fortify grain products with folic acid, adding it to flour, rice,
pasta and cornmeal.
Vitamin D could be helpful in reducing the risk for pancreatic cancer.
Lycopene is found
in tomatoes
IP-6 supplement
Triphala, an Ayurvedic
herbal combo.
Vitamin D and Pancreatic Cancer
People who take vitamin D tablets are less likely to get deadly
pancreatic cancer as people who do not. It is still early to say whether getting
the vitamin from food or sunlight also reduces the risk. Vitamin D has shown
strong potential for preventing and treating prostate cancer, and areas with
greater sunlight exposure have lower incidence and mortality for prostate,
breast, and colon cancers, leading us to investigate a role for Vitamin D in
pancreatic cancer risk. Working with colleagues at Harvard University, Dr.
Skinner's team examined data from two large, long-term health surveys involving
46,771 men between 40 and 75 years old and 75,427 women between 38 and 65. They
found that people who took the U.S. Recommended Daily Allowance of Vitamin D,
400 IU a day, had a 43-percent lower risk of pancreatic cancer. Those who took
doses of less than 150 IU per day had a 22 percent reduced risk of cancer.
Writing in the journal Cancer Epidemiology Biomarkers & Prevention, the
researchers said taking more than 400 IU a day did not reduce the risk further.
Pancreatic cancer and lycopene
Dietary intake of
lycopene is associated with reduced pancreatic cancer risk.
J Nutr. 2005 Mar;135(3):592-7.
Although fruits and vegetables have been implicated in the
etiology of pancreatic cancer, the role of phytochemicals in these food
groups has received little attention to date. In this study, we
investigated the possible association between dietary carotenoids and
pancreatic cancer risk. A case-control study of 462 histologically
confirmed pancreatic cancer cases and 4721 population-based controls in 8
Canadian provinces took place between 1994 and 1997. After adjustment for age, province, BMI, smoking,
educational attainment, dietary folate, and total energy intake, lycopene,
provided mainly by tomatoes, was associated with a 31% reduction in
pancreatic cancer risk among men when comparing the highest and lowest
quartiles of intake. Both beta-carotene and total carotenoids were
associated with a significantly reduced risk among those who never smoked.
The results of this study suggest that a diet rich in tomatoes and
tomato-based products with high lycopene content may help reduce
pancreatic cancer risk.
Diet and Pancreatic Cancer
Eating more raw vegetables every day, especially yellow and dark green
ones and cauliflower, lowers the risk of pancreatic cancer. According to a
Swedish study, eating plenty of cabbage, cauliflower, Brussels sprouts and
broccoli may offer protection against cancer of the pancreas. For the study, the
eating habits of 40,000 women and 49,000 men were monitored over seven years. Of
the total, 135 were treated for cancer of the pancreas. While researchers found
no general link between frequency of the cancer and consumption of fruits and
vegetables, those who ate plenty of cabbage were less likely to contract the
illness. Eating a lot of red meat may raise the risk for pancreatic cancer.
Pancreatic insufficiency
Pancreatic insufficiency occurs when the pancreas doesn't make enough
enzymes for adequate digestion. Pancreatic insufficiency isn't a disease but a
sign of an underlying problem. It typically results from damage to the pancreas,
such as due to chronic inflammation of the pancreas (pancreatitis) or
cystic fibrosis.
Pancreatic mass
The differential diagnosis for a solid pancreatic mass includes
adenocarcinoma (especially in light of the possible metastasis to the rib) and
islet cell tumor. It would be highly unusual for this to a metastatic mass,
since metastases to the pancreas are generally multiple and associated with
known primaries.
Cause of Pancreatic Cancer
Several causes include eating a lot of red meat, being diabetic, and
smoking.
Eating a lot of red meat, and particularly processed meat, increases the
risk of pancreatic cancer, according to findings from a large multiethnic study.
The results hint that carcinogenic substances used in meat processing rather
than the fat or cholesterol content might be responsible for the association. Nothlings, from the Cancer Research Center of Hawaii in Honolulu, and colleagues
examined the relationship between diet and pancreatic cancer in 190,545 men and
women who included African Americans, Japanese Americans, Caucasians, Latinos
and Native Hawaiians.
During an average follow up of 7 years, 482 subjects developed pancreatic
cancer.
After taking into account age, smoking status, history of diabetes, family
history of pancreatic cancer and ethnicity, subjects with the highest intake of
processed meat had a 67 percent increased risk of developing pancreatic cancer
compared to those with the lowest intake of processed meat.
A high intake of pork and total red meat increased the risk of pancreatic cancer
by about 50 percent.
Consumption of poultry, fish, dairy products, and eggs did not influence the
overall risk of pancreatic cancer, nor did overall intake of total fat,
saturated fat or cholesterol. A diet containing lots of processed meats, like hot dogs and sausages,
raises the risk of pancreatic cancer. The researchers found that heavy consumers
of processed meats -- 40 grams a day or more -- were 67 percent more likely to
develop cancer of the pancreas than study participants with the lowest intake.
In addition, a diet rich in pork and red meat -- 70 grams a day or more -- also
increased pancreatic cancer risk by about 50 percent.
Middle-aged and older Americans who are newly
diagnosed with diabetes also appear to have a higher risk of pancreatic
cancer. For three years after their diagnosis with diabetes, patients have
eight times the risk of developing pancreatic cancer, a study at the Mayo
Clinic Cancer Center found.
Smokers who consume diets rich in saturated fat may be at increased risk
of pancreatic cancer.
Insulin and Pancreatic Cancer
Exposure to higher insulin levels and insulin resistance appears to
influence the association between type 2 diabetes and pancreatic cancer.
Therefore, a diet that helps maintain normal blood sugar levels may reduce the
risk for pancreatic cancer.
Pancreatic cancer symptom
Patients typically report the gradual onset of nonspecific symptoms such
as anorexia, malaise, nausea, fatigue, and midepigastric or back pain.
Significant weight loss is a characteristic feature of pancreatic cancer.
Pancreatic cancer treatment
Treatment of pancreatic cancer depends on pancreatic cancer stage.
Pancreatic cancer survival rate also depends on the stage.
Pancreatic cancer prognosis -
pancreatic cancer life expectancy
The incidence of pancreatic carcinoma is increasing but the prognosis
remains extremely poor. The average life expectancy after being diagnosed with
pancreatic cancer is 2 to 7 months.
Protein in blood associated with
pancreatic cancer
A blood protein known as IGFBP-1 is related to body weight and physical
exercise levels and appears to be linked to pancreatic cancer risk. This may
support the association of obesity and a sedentary lifestyle with an increased
risk of pancreatic cancer. Since IGFBP-1 binds to and "sequesters" IGF-1, people
with chronically low IGFBP-1 levels would have more "free" IGF-1 in the
circulation, interacting with body cells. In theory, IGF-1 would be better able
to promote the growth of pancreatic cancer cells. Cancer Research, August 15,

Pancreatic Cancer Research Update
Dietary intake of lycopene is associated with reduced
pancreatic cancer risk.
J Nutr. 2005 Mar;135(3):592-7.
Although fruits and vegetables have been implicated in the
etiology of pancreatic cancer, the role of phytochemicals in these food
groups has received little attention to date. In this study, we
investigated the possible association between dietary carotenoids and
pancreatic cancer risk. A case-control study of 462 histologically
confirmed pancreatic cancer cases and 4721 population-based controls in 8
Canadian provinces took place between 1994 and 1997. Dietary intake was
assessed by a self-administered FFQ. Unconditional logistic regression was
used to assess associations between specific and total carotenoid intakes
and the risk of pancreatic cancer. All tests of statistical significance
were 2-sided. After adjustment for age, province, BMI, smoking,
educational attainment, dietary folate, and total energy intake, lycopene,
provided mainly by tomatoes, was associated with a 31% reduction in
pancreatic cancer risk among men when comparing the highest and lowest
quartiles of intake. Both beta-carotene and total carotenoids were
associated with a significantly reduced risk among those who never smoked.
The results of this study suggest that a diet rich in tomatoes and
tomato-based products with high lycopene content may help reduce
pancreatic cancer risk.
Inositol hexaphosphate (IP6): a novel treatment for pancreatic cancer.

Inositol hexaphosphate (IP6) is a naturally occurring polyphosphorylated
carbohydrate found in food sources high in fiber content. IP6 has been
reported to have significant inhibitory effects against a variety of
primary tumors including breast and colon. The effects of IP6 have not
been evaluated in pancreatic cancer. We hypothesized that IP6 would
significantly inhibit cell growth and increase the apoptotic rate of
pancreatic cancer in vitro. Two pancreatic cancer
cell lines (MIAPACA and PANC1) were cultured using standard techniques and
treated with IP6 at doses of 0.5, 1.0, and 5.0 mm. Cell viability was
measured by MTT at 24 and 72 h. Apoptosis was evaluated by Annexin V-FITC
and results calculated using FACS analysis. Statistical analysis was
performed by ANOVA. RESULTS: Significant reductions in cellular
proliferation were observed with all IP6 concentrations tested in both
cell lines and at both time points. Reductions in cell proliferation
ranged from 37.1 to 91.5%. IP6 increased early and late apoptotic activity. CONCLUSIONS: Treatment of pancreatic cancer with the common
dietary polyphosphorylated carbohydrate IP6 significantly decreased
cellular growth and increased apoptosis. Our findings suggest that IP6 has
the potential to become an effective adjunct for pancreatic cancer
treatment. Further in vivo and human studies are needed to evaluate safety
and clinical utility of this agent in patients with pancreatic cancer.
