Improving Lung Cancer Survival

sunsetVitamin D may help people with lung cancer to live longer, according to a study released in 2005. The most common cause of cancer death in American men and women, lung cancer can be challenging to treat effectively. The report found that men with early-stage non-small cell lung cancer who had higher vitamin D indices - based on dietary intake and exposure to sunlight- had improved recurrence-free survival rates compared to men with lower vitamin D intake and sun exposure.

Another study conducted in 2005 demonstrated that the active form of vitamin D inhibited lung cancer metastasis in an animal model of the disease. These findings suggest that implementing vitamin D therapy may be critical to improving survival rates for lung cancer patients.

Additional scientific evidence suggests that optimal vitamin D status may be associated with reduced risk of many other forms of cancer. These include cancers of the bladder, esophagus, stomach, ovary, uterus, cervix, pancreas, larynx, oral cavity, and gall bladder, as well as Hodgkin's and non-Hodgkin's lymphomas.

Lung Function and Vitamin D link identified in New Zealand Study

lungsThere may be a link between vitamin D and lung health according to a new study out of New Zealand. Researchers led by Peter Black at the University of Auckland looked at 14,091 persons over the age of 20 from the U.S. Third national health and Nutrition Examination Survey (NHANES III) carried out between 1988 and 1994. The participants had spirometry performed and had serum 25-hydroxyvitamin D measured.

The participants were divided into five groups based on vitamin D levels. Typically the higher the vitamin D levels the better the subjects performed on two lung function tests.

The first test was the FEV1 (forced expiratory volume). This measured the total amount of air blown out in the first second of maximum exhalation. The second test was the FVC (forced vital capacity) test. This test measured the amount of air blown out during a maximum exhalation.
