Questioning
Surgery for Early Prostate Cancer
A new study
shows that prostate cancer surgery, which often leaves men impotent or
incontinent, does not appear to save the lives of men with early-stage disease,
who account for most cases, and many of these men would do just as well to
choose no treatment at all.

Genetic
Aberrations Seen as Path to Stop Colon
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.
