When
Fighting Cancer Isn't Worth It
The most
aggressive treatments currently available don't guarantee success, and they
aren't right for everyone.

In
challenge to personalized cancer care, DNA isn't all-powerful
The cancer
cells were not behaving the way the textbooks say they should. Some of the
cells in colonies that were started with colorectal tumor cells were
propagating like mad; others were hardly multiplying. Some were dropping dead
from chemotherapy and others were no more slowed by the drug than is a tsunami
by a tissue. Yet the cells in each "clone" all had identical genomes,
supposedly the all-powerful determinant of how cancer cells behave.

Cancer
stem cells isolated from kidney tumors
Scientists
have isolated cancer stem cells that lead to the growth of Wilms' tumours, a
type of cancer typically found in the kidneys of young children. The
researchers have used these cancer stem cells to test a new therapeutic
approach that one day might be used to treat some of the more aggressive types
of this disease. The results are published online in EMBO Molecular Medicine.

Rembrandt's
Bathsheba did not have breast cancer after all: cientists cast new light on
famous painting
In 1654,
Rembrandt van Rijn painted his famous Bathsheba, which depicts King David's
wife naked at her bath. The painting has been regarded as an icon for breast
cancer since the 1980s, after two Australian surgeons had interpreted the blue
mark on her breast as breast cancer and wrote an article about it. Now, with
the help of computer simulations, researchers from the MIRA research institute
at the University of Twente have demonstrated that it is 'highly unlikely' that
the blue mark on Bathsheba's breast really was caused by the disease.

Cancer du sein : certaines femmes
recevront 10 ans de tamoxifène au lieu de 5
L'allongement de la durée du
traitement par tamoxifène en adjuvant à 10 ans permet de réduire le risque de
récidive tardive du cancer du sein avec expression des récepteurs aux
estrogènes (ER+) et améliore la survie, selon l'étude ATLAS (Adjuvant Tamoxifen
- Longer Against Shorter) présentée au San Antonio Breast Cancer Symposium
(SABCS) et publiée simultanément dans le Lancet.

Cancer du col: faire un frottis après test HPV positif est
gagnant
Selon une étude prospective finlandaise , le dépistage du
cancer du col de l'utérus par la recherche de l'ADN du papillomavirus humain
(HPV), couplée à un examen cytologique par frottis cervico-utérin en cas de
résultat positif, permet de détecter davantage de lésions précancéreuses,
comparativement au frottis seul.
