Study Points to Shorter Treatments for Prostate Cancer

Men with high-risk prostate cancer treated with only 18 months of hormone therapy live just as long as those treated for a more standard 36 months, a new study has found.

Report Faults Priorities in Studying Breast Cancer

Too little of the money the federal government spends on breast cancer research goes toward finding environmental causes of the disease and ways to prevent it, according to a new report from a group of scientists, government officials and patient advocates established by Congress to examine the research.

Protein Central to Cancer Stem Cell Formation Provides New Potential Target

Researchers have identified a pivotal protein in a cellular transformation that makes a cancer cell more resistant to treatment and more capable of growing and spreading, making it an inviting new target for drug development.

Lung cancer set to overtake breast cancer as the main cause of cancer deaths among European women

Lung cancer is likely to overtake breast cancer as the main cause of cancer death among European women by the middle of this decade, according to new research published in the cancer journal Annals of Oncology [1] today (Wednesday). In the UK and Poland it has already overtaken breast cancer as the main cause of cancer deaths in women.

Emerging Cancer Drugs May Drive Bone Tumors

Cancer drugs should kill tumors, not encourage their spread. But new evidence suggests that an otherwise promising class of drugs may actually increase the risk of tumors spreading to bone, according to researchers at Washington University School of Medicine in St. Louis.

Researchers Discover Biological Diversity in Triple-Negative Breast Cancer

Triple-negative breast cancers are more biologically diverse than previously believed and classification should be expanded to reflect this heterogeneity, according to University of North Carolina researchers.

Copper depletion therapy keeps high-risk triple-negative breast cancer at bay

An anti-copper drug compound that disables the ability of bone marrow cells from setting up a "home" in organs to receive and nurture migrating cancer tumor cells has shown surprising benefit in one of the most difficult-to-treat forms of cancer -- high-risk triple-negative breast cancer.

Eradicating Bacteria Linked to Gastric Cancer

In an analysis of the results of interventions to eradicate the bacterium Helicobacter pylori (a risk factor for gastric cancer) in seven diverse community populations in Latin America, researchers found that geographic site, demographic factors, adherence to initial therapy and infection recurrence may be as important as the choice of antibiotic regimen in H pylori eradication interventions, according to a study appearing in the February 13 issue of JAMA.

Amiante : 18 000 à 25 000 décès par cancer de la plèvre d'ici 2030

Le pic des décès dus au mésothéliome (cancer de la plèvre) aurait en fait déjà été atteint, selon des travaux réalisés par l'InVS en partenariat avec le Centre d'épidémiologie sur les causes médicales de décès (CépiDc) de l'Inserm.

Cancer : un virus modifié suscite l'espoir d'un nouveau traitement

Un virus génétiquement modifié pour cibler les cellules tumorales vient de montrer qu’il augmentait significativement l’espérance de vie de patients en phase terminale du cancer du foie. Nommé Pexa-Vec et testé également pour d’autres cancers, il semblerait là encore plutôt efficace. Si tout se passe bien, il pourrait être proposé d’ici 5 ans.

Des nanoparticules d'or radioactives contre le cancer

Les noyaux d’hélium produits par radioactivité alpha sont très efficaces pour tuer des cellules cancéreuses. Ils le sont malheureusement aussi pour tuer les cellules saines, ce qui a jusqu’ici posé problème pour lutter contre les cancers. On apprend comment contourner l'obstacle grâce aux nanotechnologies : en utilisant des nanoparticules d’or.
