Elwood V. Jensen, Pioneer in Breast Cancer Treatment, Dies at 92
Elwood V. Jensen, a medical researcher whose studies of steroid
hormones led to new treatments for breast cancer that have been
credited with saving or extending hundreds of thousands of lives, died
on Dec. 16 in Cincinnati. He was 92.

US cancer screening rates decline over the last 10 years, finds new
study
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 of Medicine study published on
December 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 at the Dana-Farber Cancer Institute
and Harvard Medical School have identified a genetic mutation that
actually results in a more robust transition from a precancerous to
cancerous state when exposed to androgen deprivation.

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.

Breast cancer cells interact with non-cancerous tissue to drive
metastasis
In addition to mutations, environmental conditions created by the
tissues surrounding tumors (stroma) play a major role in cancer
progression. Researchers led by Gregg Semenza at Johns Hopkins
University examined the interactions between breast cancer cells and
the stroma to identify underlying pro-metastatic molecular mechanisms.

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.

Cyclin D1b is a genetic reprogrammer that drives cancer progression
Researchers led by Karen Knudsen at Thomas Jefferson University's
Kimmel Cancer Center examined the role of cyclin D1b in prostate
cancer.

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.

Cancer de la prostate: Un virus caché dans un macrophage pour tuer la
tumeur
C’est à nouveau l’approche par virus oncolytique, un virus capable
d’infecter uniquement les cellules cancéreuses et de les détruire, qui
vient d’être testée pour le traitement du cancer avancé de la prostate
chez l'homme.

Le dépistage du cancer du col de l'utérus gratuit dès le 1er janvier
Le dépistage du cancer du col de l'utérus sera gratuit dans quelques
jours. Les frottis (qui coûtent aujourd'hui 13 euros aux patientes)
seront intégralement remboursés. C'est l'une des décisions prises
vendredi soir lors du dernier Conseil des ministres de l'année.

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.
