The rate of
people who seek preventive cancer screenings has fallen over the last ten years
in the United States with
wide variations between white-collar and blue-collar workers, according to a University of Miami Miller School 27 in
the open-access journal Frontiers in Cancer Epidemiology.

Anti-Androgen
Therapies to Prevent Prostate Cancer Are Not One Size Fits All
A new study
suggests that chemoprevention with anti-androgen therapies may not benefit all
patients at risk for prostate cancer and could cause harm to some. Researchers

Ability
to Metabolize Tamoxifen Affects Breast Cancer Outcomes
For nearly a
decade, breast cancer researchers studying the hormone therapy tamoxifen have
been divided as to whether genetic differences in a liver enzyme affect the
drug's effectiveness and the likelihood breast cancer will recur. A new study
by researchers from the Mayo Clinic Cancer Center and the Austrian Breast and
Colorectal Cancer Study Group provides evidence that genetic differences in the
enzyme CYP2D6 play a key role in how well tamoxifen work.

NIH
study suggests gene variation may shape bladder cancer treatment
Patients who
have inherited a specific common genetic variant develop bladder cancer tumors
that strongly express a protein known as prostate stem cell antigen (PSCA),
which is also expressed in many pancreatic and prostate tumors, according to
research at the National Institutes of Health.

Bowel cancer
gene discovery cracks mystery of families with a strong history of the disease
Cancer
Research UK-funded scientists have discovered that two gene faults increase the
risk of bowel cancer in families with a strong history of developing the
disease, who, until now, had no explanation as to why their risk was greater.
The research is published in Nature Genetics.

What
Is a Meaningful Increased Survival?
In their
quest for new agents, pharmaceutical researchers test millions of substances
all over the world. They like using color-forming reactions to identify new molecules.
However, in intensively colored solutions or in the case of mixtures with
multiple substances these tests fail. As part of his doctoral thesis, Martin
Stein, member of staff at the Chair of Biochemistry at the Technische
Universitaet Muenchen, developed a testing reaction based on magnetic resonance
data. It helps find a specific pharmaceutical molecule among hundreds of
different substances even in the most turbid of bacterial brews

Découverte de deux gênes responsables du cancer de
l'intestin
Des chercheurs britanniques pensent avoir trouvé pourquoi
certaines familles sont très exposées au cancer de l’intestin. Deux gênes,
transmis par les parents aux enfants, seraient en effet responsables de
l’augmentation du risque de formation d'une tumeur.

La cigarette affecterait les gènes du cancer
Le fait de fumer des cigarettes pourrait affecter les gènes
du cancer dans l’ADN, montrant que la consommation de tabac altèrerait
chimiquement l’activité des gènes faisant augmenter le risque de cancer.
