> Vitamin C intake offers protection against stomach cancer

>

> 18/10/2004 - Further evidence shows that vitamin C intake and fruit

> consumption may be linked to reduced risk of stomach cancer.

>

> The study also shows that lycopene, an antioxidant found in tomatoes,

> could have a protective effect against the cancer although the

> researchers caution that this needs further research.

>

> The team from the US National Cancer Institute and National Public

> Health Institute of Finland assessed the association between fruit and

> vegetable consumption and the risk of stomach cancer in approximately

> 29,000 male smoker participants, aged 50 to 69, of the

> Alpha-Tocopherol, Beta Carotene (ATBC) cancer prevention study in Finland.

>

> This trial, initiated to test the effect of vitamin supplementation on

> the prevention of lung and other cancers, ended in 1993 but ongoing

> follow-up of the participants continues, offering new insights into

> the causes and prevention of multiple diseases.

>

> Speaking yesterday at this year's Frontiers in Cancer Prevention

> Research conference (abstract 173), the US and Finnish scientists said

> they had found fruit and vitamin C intake, but not vegetable

> consumption, reduced risk of non-cardia cancer approximately 45 per cent.

>

> Non-cardia cancer is the major form of stomach cancer in most parts of

> the world. Stomach cancer is the second most frequent cause of cancer

> deaths worldwide, with an estimated 776,000 deaths in 1996, and the

> fourth most common cancer. In the UK stomach cancer is the sixth most

> common cancer with 10,000 new cases each year.

>

> " Since our findings are similar to the results found in several other

> studies, fruit and vitamin C intake are likely to be useful for the

> prevention of stomach cancer, " said Farin Kamangar of the Cancer

> Prevention Studies Branch at the National Cancer Institute, and one of

> the lead investigators of the study.

>

> Last year researchers at the San Francisco VA Medical Center found

> that the lower the level of vitamin C in the blood the more likely a

> person will become infected by Helicobacter pylori, the bacteria that

> can cause peptic ulcers and stomach cancer. Although it was not clear

> whether the presence of the bacteria lowered blood levels of the

> vitamin, or whether vitamin C levels could protect against it, other

> studies have also seen low blood levels of vitamin C in people with

> the cancer.

>

> In Japan, where rates of the cancer are much higher than in the west,

> researchers have linked a diet of highly salted food containing little

> vitamin C, with a twofold risk of the cancer.

>

> Another component of fruit, lycopene, which is already associated with

> reduction of breast and prostate cancer risk, also appeared to lower

> chances of stomach cancer by 34 per cent.

>

> But the effect of lycopene on gastric cancer " needs further studies " ,

> warned Dr Kamangar.

>

> Recent research suggests that lycopene may reduce risk of cancer by

> activating special cancer preventive enzymes, rather than through its

> antioxidant effect.

> reported the researchers.
