Since cancer tumors are thought to depend on large amounts of glutamine to achieve rapid growth, some have speculated that glutamine deprivation is a therapeutic approach.
A new study casts doubt on that.
Numerous studies have indicated that tumore cannot survive without glutamine, and this has fueld the idea that preventing “glutamine addiction” could be a potential therapeutic strategy. A study now concludes that while glutamine deprivation will halt the proliferation of certain tumor cells, most of them will not be killed
, raising questions of whether such a therapeutic intervention will lead to remission in cancers.
Telomeres, repeated sequences of DNA that shorten every time a cell divides, have been linked to an increased cancer risk. The length of the telomere “caps” of DNA that protect the tips of chromosomes may provide an avenue for future therapy.The researchers presenting at American Association for Cancer Research
analyzed blood samples and health data on more than 28,000 Chinese people enrolled in the Singapore Chinese Health Study, which has followed the health outcomes of participants since 1993. As of the end of 2015, 4,060 participants had developed cancer.
If you read the claims of environmental groups, trace levels of chemicals are the source of most cancers, even if they are well below harmful levels, due to vague claims of "bioaccumulation." If you read the recent claims of the EPA, air pollution is causing acute deaths, even though the United States has some of the cleanest air in the world and no one can find any deaths it has caused during the entire existence of the EPA.
A new observational study claims that cheese increases breast cancer risk, while yogurt can lower it. Since both are dairy, that means they would be suggesting a dairy process causes or prevents cancer.
The case control study has numerous confounders that will not be noticed by most journalists so media outlets looking for context beware.
Young patients with acute lymphocytic leukemia, the most common type of pediatric cancer, are likely to report that they adhered to their anti-cancer medication better than they really did.
And so do their parents.
Studies show that over 95 percent of prescribed doses must be taken to be effective but a new analysis instead finds that that 84 percent of patients or their parents over-reported adherence to a regimen of the oral maintenance therapy6-mercaptopurine (6MP), which is prescribed for two years after chemotherapy for patients to achieve durable remissions.
Newborns with the common virus in the herpes family known as congenital cytomegalovirus have an increased risk of developing acute lymphocytic leukemia, according to a new analysis
. The authors say the risk is even greater in Hispanic children, who are already at the highest risk for developing ALL.
Women taking tamoxifen for breast cancer were less likely to continue taking the drug if they suffered nausea and vomiting - yet so were women given a placebo who experienced the same symptoms. This is evidence that drugs are being unfairly blamed for natural symptoms.
It's a chemophobia culture. People embrace homeopathy, naturopathy and various alternative techniques because they aren't required to have elaborate disclosures of side effects like real medicines have. And there is a culture war against drug companies, so if symptoms occur it may be easy to blame Big Pharma or Big Generic.
Currently, prostate-specific antigen (PSA) and other biomarkers are used for diagnosing and monitoring prostate cancer. However, biomarkers to selectively identify patients with high risk of recurrence, those who might benefit from intervention, and those who can safely choose active surveillance, are lacking. A new study in The Journal of Molecular Diagnostics describes a biomarker, PITX2 DNA methylation, which is capable of distinguishing cancerous tissue from non-cancerous tissue and predicting the risk of cancer recurrence using only small amounts of tissue obtained from core needle biopsies.
There is no clear cut-off age to stop breast cancer screening, according to a new analysis which adds support for guidelines that encourage screening decisions based on individual patients and their health status. But which puts doctors, hospitals and insurance companies at risk in a defensive medicine environment where there are unlimited potential damages if an attorney gets a cancer patient in front of a jury.
How cancer can suddenly reappear months, or years after treatment is complete is an ongoing mystery in incology.A new study
finds dormant tumor cells might have become latent because they cannibalized—basically ate—the body’s own stem cells. The team had been working on teaching adult stem cells from bone marrow, called mesenchymal stem/stromal cells (MSCs), to fight cancer when they noticed that the MSCs were disappearing from the cell cultures.
