Gastric Cancer 'GC1' Nutraceutical

Gastric or stomach cancer is the fourth most common cancer worldwide. Infection by the ulcer-causing bacteria Helicobacter pylori is believed to be a major cause of stomach cancer, although diet, smoking, and genetic factors are also associated with increased risk levels. Over the past decade many studies have investigated specific nutrients in the diet which may have a protective effect against gastric cancer. We have formulated a "nutraceutical" daily dietary supplement containing an optimised mix of three of these promising compounds - ascorbic acid, beta-carotene and alpha tocopherol - using quantities and purities specifically based on these studies. They have proven activity against cancer cells and are safe, well-studied and well-tolerated organic compounds. 2 tablets to be taken daily on an ongoing basis.

Clinical studies at a glance

Hundreds of published studies involving hundreds of thousands of patients have demonstrated that the compounds in our "GC1" nutraceuticals have the following anti-cancer properties:

 - They are able to directly trigger cell death in gastric cancer cells, as well as helping to prevent the recurrence of cancer in some patients by decreasing DNA damage in the cells of the stomach.

 - They help to both eradicate Helicobacter pylori, the bacteria that causes gastric ulcers which can lead to cancer, and also protect against its recurrence. They also protect against gastric damage resulting from the bacteria, and ease inflammation of the stomach.

 - They can help suppress the ability of gastric cancer cells to move around the body, thereby helping to protect against metastasis and cancer cell invasion.

 - Regular consumption of the above compounds also offers some protection against the development of both gastric and oesophageal cancer.

Note: Supplements containing beta-carotene are not recommended for regular smokers.

Modes of Action

Ascorbic acid is a essential nutrient found primarily in fruits and vegetables and is a potent antioxidant. In a recent study it was shown trigger apoptosis (pre-programmed cell death) in cultured gastric cancer cells (Ha, et al. 2009). It is also thought to help in the prevention of gastric cancer by decreasing gastric oxidative stress which prevents DNA damage that can lead to the formation of cancerous cells (Oliveira, et al. 2003); by helping to eradicate Helicobacter pylori, the bacteria that causes gastric ulcers which can lead to cancer (Sezikli, et al. 2009; Zojaji, et al. 2009); and by modulating the immune system to prevent chronic inflammation (Sun, et al. 2005; Ernst 1999).

Alpha tocopherol is a fat-soluble antioxidant found in some vegetables, eggs, milk, and some nuts. Tocopherols have been shown to significantly inhibit behaviours in cultured gastric cancer cells that result in the development of metastasis and the invasion of these cells into tissues in the body (Liu, et al. 2009), as well as trigger their death directly (Sun, et al. 2009). Alpha tocopherol has also been shown in animal models (Sugimoto, et al. 2006) to significantly protect against gastric damage and ease inflammation as a result of Helicobacter pylori infection. In addition, alpha tocopherol has the ability in animal models to directly trigger gastric cell death and inhibit cellular proliferation (Olguín-Martínez, et al. 2006).

Beta-carotene is a precursor to vitamin A, and found in high concentrations in orange vegetables, some green leafy vegetables, and some oils. It is known trigger apoptosis and DNA damage in cultured gastric cancer cells (Jang, et al. 2009). It can also protect against gastrointestinal damage (Mózsik, et al. 1998). Beta-carotene combined with antioxidants including ascorbic acid and alpha tocopherol also significantly protects against infection with Helicobacter pylori and gastritis (Sjunnesson, et al. 2001).

Relevant Clinical Studies - TREATMENT

In a one study (Correa, et al. 2000), 852 individuals, many with precursors of gastric cancer and all at high risk of developing new stomach tumours, were given either anti-Helicobacter therapy (the standard 14-day treatment used to kill Helicobacter pylori, the bacteria that causes the gastric ulcers which lead to cancer), or ascorbic acid daily, or beta-carotene daily, or combinations of all three. After six years, patients in this study taking any one of these three treatments were on average 3 times more likely to have had "histologic regression" (when cancerous cells or tissues in the stomach return to a more normal, non-cancerous appearance) than those patients taking a placebo, and patients taking a combination of these three treatments were three to five times more likely to have histologic regression (however it is important to note that some of the combinations were not statistically significant despite the strong trend towards increased rates of regression). Likewise in a similar study (Mannick, et al. 1996) which included 103 patients, daily ascorbic acid and beta-carotene for 4-12 months augmented the effect of the anti-Helicobacter therapy, increasing the percentage of patients able to clear the infection, and also significantly decreasing the oxidative damage which leads to the formation of new cancer cells.

Two other large studies have shown less clear effects. While one study (Plummer, et al. 2007) suggested that beta-carotene and ascorbic acid tended to have a beneficial effect on the regression and progression of pre-cancerous gastric lesions (with the 1383 patients taking beta-carotene, ascorbic acid, and alpha tocopherol daily having an average 25% decrease in progression, and a 30% increase in regression of their pre-cancerous lesions and also a small decrease in the rates of Helicobacter infection), in this case these outcomes did not reach statistical significance. Likewise, a large study including 29,584 participants (Blot, et al. 1993) over >5 years, showed that there were 24.7% less cancer deaths in individuals taking ascorbic acid, beta-carotene, and alpha tocopherol daily (in addition to molybdenum and selenium) compared to those taking a placebo. However, only the supplement containing beta-carotene showed a significantly beneficial effect on mortality from gastric cancer specifically - with a 23% decrease in death from gastric cancer in patients taking the supplement for at least one year.

Finally, two studies (Omenn, et al. 1996; ATBC Group 1994) presented evidence that very high doses of beta-carotene increase the risk of lung cancer specifically in regular cigarette smokers. It is thought that cigarette smoke increases the asymmetric cleavage of beta-carotene, which in turn decreases the level of the oxidised form of Vitamin A (retinoic acid), which can promote lung cancer cell proliferation. Although a later study (Hennekens, et al. 1996) disputed these findings, in the interests of caution we would strongly recommend that current smokers do not take any supplement containing beta-carotene.

Relevant Clinical Studies - Prevention OF NEW TUMOURS

A number of clinical trials have been undertaken to determine whether ascorbic acid, beta-carotene, and alpha-tocopherol have protective effects against gastric cancer. Combining 10 of these independent clinical studies into a single analysis which included 1057 patients with oesophageal cancer and 644 patients with gastric cancer (Kubo, et al. 2007), it was shown that individuals with a high intake of ascorbic acid were 26% less likely to develop gastric cancer and 51% less likely to develop oesophageal cancer than those who had a low intake. Likewise, those with a high intake of beta-carotene were 43% less likely to get gastric cancer and 54% less likely to get oesophageal cancer than those who had a low intake. A similar recent independent study (Pelucchi, et al. 2009) which in addition looked at the effects of alpha tocopherol on 230 gastric cancer patients and 547 matched controls showed similar results, demonstrating that beta-carotene and alpha tocopherol both significantly protected against gastric cancer, whereas the 17 other micronutrients analysed in the same study had no significant effect. In contrast to the previously mentioned meta-analysis of 10 studies however, in this case the protective effect of ascorbic acid did not reach statistical significance, although there did remain a trend towards protection against gastric cancer in patients consuming the highest rates of ascorbic acid consumption, with these individuals having on average a 33% lower risk of gastric cancer than control patients who had a lower intake.

Other Known Effects

Ascorbic acid, beta-carotene, and alpha tocopherol are important micronutrients for humans and have a range of other important roles in the body.

Ascorbic acid is required for a range of essential metabolic reactions, and is a strong antioxidant. Antioxidants neutralize free radicals, thereby preventing oxidative stress which can cause cardiovascular diseases, hypertension, chronic inflammatory diseases and diabetes, among other things. Some scientific evidence also suggests it has a beneficial role on the immune system, asthma, ischemic heart disease, and stroke prevention, however further work is ongoing to determine this conclusively.

Beta-carotene is also an antioxidant and is a precursor of Vitamin A. Vitamin A is required for normal bone development, functioning of the reproductive system, and cellular growth and proliferation. In addition there is some weak scientific evidence to suggest that beta-carotene is also beneficial for increasing cognitive performance and memory, immune system enhancement, and decreasing the severity of osteoarthritis.

Alpha tocopherol is also an important antioxidant with many functions within the body. Deficiency of alpha tocopherol can lead to neurological problems and anaemia. There is some limited evidence that alpha tocopherol may protect against Parkinson's disease, glaucoma, and blood clots, and when combined with other antioxidants such as ascorbic acid, may be protective against age-related macular degeneration.
