Press review  (August 20, 2011) – Revue de presse (20 août 2011)


FDA approves Seattle Genetics cancer drug
The Food and Drug Administration approved Seattle Genetics' Adcetris
to treat two types of relatively rare blood cancers -- Hodgkin's
lymphoma and anaplastic large cell lymphoma (ALCL).

Doctors screen for cervical cancer too often‎

than guidelines suggest, according to a new study.

Chromosomes and Cancer
Aneuploidy—when the cells of an organism contain more or fewer than
the standard number of chromosomes for its species—is found in greater
than 90 percent of all human cancers. But how exactly it relates to
cancer, and whether it is a cause or merely a consequence of genomic
instability, has long been a mystery. Two new studies published today
(August 18) in Science show that it’s probably both, pointing to a
gene defect that can cause aneuploidy, and elucidating the disastrous
effects of aneuploidy on a cell’s genome. By Jef Akst. In The
Scientist

How Caffeine Fights Cancer
Caffeinated drinks may help prevent skin cancer by inhibiting a DNA
repair pathway, thus killing potentially precancerous cells.

Fast FDA Approval of Melanoma Drug‎
The Food and Drug Administration approved an expensive new melanoma
drug (vemurafenib, brand name Zelboraf) much faster than expected,
giving a boost not only to that drug but also to other experimental
products that may offer gene-based personalized medicine. By Duff
Wilson. In The New-York Times (blog)

Cancer stem cells made, not born
Experiments and modeling reveal how tumors maintain cellular balance.

Some Thyroid Cancer Patients May Get Radioactive Iodine Unnecessarily
Some thyroid cancer patients with early disease may be given
radioactive iodine unnecessarily, while others with more advanced
tumors who should get the treatment don't, a new study suggests.
By Jenifer Goodwin. In U.S. News & World Report

Cancer's Secrets Come Into Sharper Focus‎
Understanding how cancer begins and then grows is fundamental to one
day preventing the disease. Here, we explain three new theories for
how cancer may form. By George Johnson. In The New-York Times
http://www.nytimes.com/2011/08/16/health/16cancer.html

Tiny genetic error responsible for hereditary cancer‎
A single hereditary error in DNA can cause a key anti-cancer gene to
switch off, giving a greater risk of developing cancer.
By Tim Dean. In Australian Life Scientist
http://www.lifescientist.com.au/article/397579/tiny_genetic_error_responsible_hereditary_cancer/

Cancers generate muscle-like contractions to spread around the body‎
Scientists have discovered that a protein called JAK triggers
contractions in tumours which allows cancer cells to squeeze though
tiny spaces and spread, in research published in Cancer Cell.

Cancers du sang: des chercheurs anglais travaillent sur un dérivé de
l'ecstasy
Des chercheurs de l'université anglaise de Birmingham ont découvert
une forme modifiée de l'ecstasy (MDMA), 100 fois plus efficace pour
détruire les cellules cancéreuses que la drogue elle-même, ouvrant la
voie à une possible application thérapeutique.
