Five-year survival rates of melanoma patients treated by diet therapy after the manner of Gerson: a retrospective review.

OBJECTIVE:
Compare 5-year melanoma survival rates to rates in medical literature.

DESIGN:
Retrospective.

SETTING:
Hospital in Tijuana, Mexico.

PATIENTS:
White adult patients (N = 153) with superficial spreading and nodular melanoma, aged 25-72 years.

The effect of vitamin E and beta carotene on the incidence of lung cancer and other cancers in male smokers. The Alpha-Tocopherol, Beta Carotene Cancer Prevention Study Group.

BACKGROUND:
Epidemiologic evidence indicates that diets high in carotenoid-rich fruits and vegetables, as well as high serum levels of vitamin E (alpha-tocopherol) and beta carotene, are associated with a reduced risk of lung cancer.

A meta-analysis of studies of dietary fat and breast cancer risk.

There is strong evidence that breast cancer risk is influenced by environmental factors, and animal experiments and human ecological data suggest that increased dietary fat intake increases the incidence of the disease. Epidemiological evidence on the relationship of dietary fat to breast cancer from cohort and case control studies has however been inconsistent. To examine the available evidence we have carried out a meta-analysis to summarise quantitatively the large published literature on dietary fat in the aetiology of breast cancer.

Intake of fat, meat, and fiber in relation to risk of colon cancer in men.

Some evidence suggests that diets high in animal fat or red meat may increase the risk of colon cancer, whereas high intake of fiber or vegetables may be protective. Frequently, intake of red meat has been a stronger risk factor than total fat. Because data from prospective cohort studies are sparse, we examined fat, meat, fiber, and vegetable intake in relation to risk of colon cancer in a cohort of 47,949 U.S. male health professionals who were free of diagnosed cancer in 1986.

Egg consumption and cancer of the colon and rectum.

We systematically reviewed 15 previous case-control and cohort studies that examined egg consumption as a risk factor for cancers of the colon andrectum. Nine of the 11 studies of colon cancer reported risk estimates consistent with a positive association; in three of these studies the association was statistically significant. The positive association for egg consumption was generally stronger for females than for males, and for cancer of the proximal, rather than distal colon.
