Questioning Surgery for Early Prostate Cancer‎‎‎

Genetic Aberrations Seen as Path to Stop Colon Cancer‎
More than 200 researchers investigating colon cancer tumors have found genetic vulnerabilities that could lead to powerful new treatments. The hope is that drugs designed to strike these weak spots will eventually stop a cancer that is now almost inevitably fatal once it has spread.

Deadly Liver Cancer May Be Triggered by Cells Changing Identity‎‎‎
A rare type of cancer thought to derive from cells in the bile ducts of the liver may actually develop when one type of liver cell morphs into a totally different type, a process scientists used to consider all but impossible. UCSF researchers triggered this kind of cellular transformation -- and caused tumors to form in mice -- by activating just two genes.

Cancers et essais nucléaires : un rapport établit un lien vraisemblable‎
Selon le spécialiste Florent de Vathaire, les retombées radioactives des essais nucléaires français au Sahara et en Polynésie sont possiblement à l’origine de certains cas de cancer chez des militaires et des professionnels du nucléaire. Le lien ne pourra pourtant jamais être établi avec certitude.

L'Avastin n'améliore pas la survie globale dans le cancer du sein avancé
Selon une revue systématique de la Cochrane Library, l'antiangiogénique, anticorps monoclonal anti-VEFG, bévacizumab (Avastin®, Roche) offre un bénéfice modeste en termes de survie sans progression et aucun bénéfice en termes de survie globale chez les patientes atteints d'un cancer du sein métastatique qui le reçoivent en association avec une chimiothérapie classique.
