Cancer Research of Interest

In the natural health field we are accustomed to thinking about cancer very differently than the way they do in the medical field. But a recent paper has hit the medical literature that may start to change things. Well maybe in the next century or so as things do not evolve easily when monopolies are in control…

Here is the synopsis:

In a study of more than 1,200 patients, published in the Friday, August 3, issue of Oncotarget, an international team of 35 co-investigators from 17 institutions spanning the U.S., Brazil and Europe reported that cancer occurs because cancer cells make and use energy differently from normal cells. The new study finds that cancer is a metabolic disorder which challenges decades of genomic research.

“This suggests that cancer is not a genetic disease arising solely from mutations as we have all been taught, but instead a metabolic condition that develops under the stress of cellular nutrient deprivation,” said Robert Nagourney, MD, senior author of the study. “Cells that cannot generate enough energy due to lack of oxygen, sugars or proteins, common to many cancers, use altered metabolic pathways to ensure their survival. Unfortunately these cancer cells’ success comes at the expense of the host patient,” Nagourney added.

Using mass spectrometry to measure minute quantities of sugars, amino acids and lipids in the blood of cancer patients, these scientists foundmetabolic signatures that clearly identified breast cancer patients with a greater than 95 percent accuracy. Breast cancer patients have changes in their metabolism that “predispose” them to the development of their disease.

The findings support a new concept of carcinogenesis wherein cancer is not caused by mutations. By examining almost 200 different chemicals in the blood stream and comparing cancer patients to controls, the team of investigators showed striking differences that clearly separated normal people from cancer patients.

The implications of the study are profound as it introduces a new platform for early diagnosis, provides prognostic information for response and survival, and offers insights into novel strategies for cancer prevention. Additional studies are underway to extend these findings to other forms of cancer. Mass spectrometry is a technique that can accurately measure the content of body fluids like blood or urine. Using ion vaporization, exceedingly small amount of metabolites can be quantified and compared. As little as 10 microliters of blood (one drop) can be used.
