Researchers are studying high dose vitamin C as part of treatment for several cancers, including pancreatic cancer. These high doses of vitamin C (pharmacologic ascorbate) are not taken orally (by mouth), but in IVs (taken intravenously). It is always given alongside chemotherapy.

The intravenous vitamin C doses are 150 to 190 times larger than ordinary vitamin C tablets that are taken orally. This is because orally taken vitamin C cannot reach the blood levels needed to produce a pharmacologic effect.

Some of the results are amazing. For example, persons with pancreatic cancer it doubled survival compared to chemotherapy alone (from 8 months to 16 months) , and those receiving vitamin C used alongside standard chemotherapy had fewer side effects than when using chemotherapy alone. It is still unclear for which cancers the vitamin C treatment works and for which it doesn't.

The only problem is that pharma companies may not be interested because it can not be patented, and can't be developed as a new drug that they can make big profits off of. It's plain old vitamin C - but not as a nutritional supplement, but used as a medical drug (pharmacologic ascorbate).

The pancreatic cancer treatment field is on fire. This is very good news because pancreatic cancer is an aggressive cancer that is typically diagnosed at late stages, and with a low survival rate (5 year survival rate of 15%).

There are a number of different treatments now undergoing clinical trials - from several vaccines, immunotherapy, the drug daraxonrasib that doubles life expectancy in those with pancreatic cancer, to other interesting treatments such as high dose vitamin C (given via IV).

The most exciting are pancreatic vaccines that are now undergoing clinical trials. They are meant to be used after a pancreatic cancer diagnosis - the goal is to prevent a recurrence of the cancer and to kill any remaining pancreatic cancer cells. They involve a person's own immune system attacking or suppressing the pancreatic cancer. Amazing research and progress is being made.

Pancreatic cancer is typically discovered only when it is advanced, very hard to treat, and typically with poor outcomes. Interesting recent research found that the gut microbiome is distinctive in persons with pancreatic cancer, even in the early stages. Perhaps this finding will lead to an easy noninvasive way to screen for pancreatic cancer.

Researchers in Spain and Germany looked at both the community of microbes (microbiome) living in the mouth and the gut (shown in a person's feces). They took samples from healthy persons, individuals with pancreatic cancer, and persons with chronic pancreatitis  and found that the bacteria in the stool were predictive for pancreatic cancer (but not those in the mouth).

The "fecal microbiota signature" or pattern of microbes in those with pancreatic cancer had an increase in some microbes (e.g., Fusobacterium nucleatum) and a decrease in others (e.g., Faecalibacterium prausnitzii) - when compared to healthy individuals.

By the way, Fusobacterium nucleatum is found increased in other cancers, such as colon cancer, and beneficial and anti-inflammatory Faecalibacterium prausnitzii is reduced in a number of diseases. Eating a diet rich in high fiber foods (whole grains, fruits, vegetables, legumes, seeds, nuts) increase the numbers of F. prausnitzi in a person's gut microbial community.

A specific panel of gut microbes may identify pancreatic cancer, irrespective of how far the disease has progressed, suggests research published online in the journal Gut. ...continue reading "Pancreatic Cancer Has a Distinct Gut Microbial Pattern"

This latest study finding health benefits of eating nuts was a review of 36 observational studies, involving a total of 30,000 people. Nut consumption was associated with a lower risk of cancer in general, and a decreased risk of some types of cancer (colorectal, endometrial, pancreatic), but not with type 2 diabetes. So go ahead - eat a small handful of nuts for your health at least several times a week.From Medpage Today:

A Nutty Way to Prevent Cancer?

Nut consumption was associated with a decreased risk of some types of cancer but not with type 2 diabetes in a large review.When patients eating the most nuts were compared with those eating the least, those in the first group had a lower risk of colorectal cancer in three studies (RR 0.76, 95% CI 0.61-0.96; I2=51.3%), of endometrial cancer in two studies (RR 0.58, 95% CI 0.43-0.79; I2=0%), and pancreatic cancer in one study (RR 0.68, 95% CI 0.48-0.96; I2 not available). Those results were reported in the meta-analysis of 36 observational studies, with a total population of more than 30,000 patients.

Nut consumption was also associated with a lower risk of cancer in general (RR 0.85, 95% CI 0.76-0.95;I2=66.5%), according to the authors. But it was not associated with other types of cancer or with type 2 diabetes (RR 0.98, 95% CI 0.84-1.14; I2=74.2%), found the researchers, who were led by Lang Wu, a PhD candidate at the Mayo Clinic. They published their results on June 16 in Nutrition Reviews.

"Overall, nut intake was associated with a decreased risk of cancer," wrote Wu and colleagues. "Given the scarcity of currently available data, however, evidence from additional studies is required to more precisely determine the relationship between nut consumption and risk of individual cancer types." Evidence for the association between nuts and cancer has been mixed, according to the authors. Follow-up time in the studies ranged from 4.6 years to 30 years, found the review.

The amount of nuts eaten ranged from none for some of the patients to eating nuts more than seven times a week....No associations were found between nut consumption and acute myeloid leukemia, breast cancer, gastric cancer, glioma, hepatocellular carcinoma, leukemia, lymphoma, ovarian cancer, prostate cancer, or stomach cancer.
