<H2 class=3Dsubtitle></H2><B>Virus-Drug Combination May Have Synergistic =
Effect=20
Against Glioblastoma </B><BR>A new study has found that a cancer drug =
and an=20
engineered form of the herpes simplex virus may work together more =
effectively=20
than either agent alone to destroy glioblastoma cells from human brain =
cancers.=20
<P>The drug temozolomide, which stops tumor growth by preventing DNA =
replication=20
in the cell, was approved in 2005 for the treatment of glioblastoma, a =
rapidly=20
fatal type of brain cancer. However, some glioblastomas do not =
completely=20
respond to this drug because the cancer cells repair DNA damage induced =
by the=20
drug before the damage forces the cell to die.=20
<P>Manish Aghi, M.D., Ph.D., of the Massachusetts General Hospital in =
Boston,=20
and colleagues paired temozolomide with an oncolytic, or cancer killing, =

genetically engineered form of the herpes simplex virus called G207. =
They tested=20
both agents together and separately in cancer cells and in mice with =
gliomas.=20
Their laboratory studies on human cancer cells found that the virus and =
the drug=20
act synergistically in cancer cells to promote cell death. Mice with =
brain=20
gliomas treated with both the virus and the drug survived more than =
twice as=20
long as those treated with either agent alone.=20
<P>"Glioma treatment with temozolomide and G207, possibly giving =
temozolomide=20
before inoculating virus during surgery to take advantage of=20
temozolomide-induced DNA repair in residual glioma cells, warrants a =
clinical=20
trial," the authors conclude.=20

<P><B>Autoimmune Disorders Associated with Risk of Non-Hodgkin Lymphoma=20
</B><BR>A new study confirms that certain autoimmune and inflammatory =
disorders=20
are associated with an increased risk of non-Hodgkin lymphoma (NHL), a =
type of=20
cancer that occurs in the lymphatic system. The study also examines the=20
association between these disorders and specific subtypes of NHL.=20
<P>Past studies have consistently found an association between certain=20
autoimmune disorders (such as lupus, rheumatoid arthritis, and Sj=F6gren =
syndrome)=20
and NHL, but results have been more inconsistent for related disorders =
(such as=20
inflammatory bowel disorders, psoriasis, and sarcoidosis). To further=20
characterize these associations and to determine if certain disorders =
are=20
associated with specific subtypes of NHL, Karin Ekstr=F6m Smedby, M.D., =
at the=20
Karolinska Institute in Stockholm, Sweden, and colleagues interviewed =
3055 NHL=20
patients and 3187 control subjects about their history of autoimmune and =

inflammatory disorders.=20
<P>The authors found that rheumatoid arthritis, primary Sj=F6gren =
syndrome,=20
systemic lupus erythematosus, and celiac disease were associated with an =

increased risk of developing NHL. Other similar conditions--type I =
diabetes=20
mellitus, inflammatory bowel disorders, psoriasis, and sarcoidosis--were =
not=20
associated with increased risk of NHL. Specific disorders were =
associated with=20
an increased risk of specific NHL subtypes; for example, there was a =
positive=20
association between rheumatoid arthritis, Sj=F6gren syndrome, lupus, and =
celiac=20
disease and risk of a subtype of NHL called diffuse large B-cell =
lymphoma. The=20
authors suggest that their findings may serve as a model understanding =
the=20
mechanism by which NHL develops in patients without autoimmune or =
inflammatory=20
conditions.=20

<P><B>Study Examines Reliability of Self-Reported Family History of =
Cancer=20
</B><BR>Differences in accurately reporting a family history of cancer =
between=20
cancer patients and control subjects may bias results in some studies of =
family=20
cancer risk, according to a new study.=20
<P>Ellen T. Chang, Sc.D., now of the Northern California Cancer Center, =
and=20
colleagues at the Karolinska Institute in Stockholm, Sweden, compared=20
questionnaire data and registry data on family history of cancer from =
1508=20
lymphoma patients and 1229 control patients. Cancer patients correctly =
reported=20
verified (true positive) cases of cancer, especially lymphomas and =
leukemias, in=20
family members more often than those in the control group, but cancer =
patients=20
also reported unverified (false positive) cases of family cancer =
slightly more=20
often than control subjects.=20
<P>The authors write that self-reported data on family cancer history, =
"are far=20
from perfectly reliable." "Future observational studies," they suggest, =
"should=20
make any possible effort to validate both positive and negative =
self-reports of=20
cancer in family members."=20

<P><B>Study Examines Association Between Carbonated Soft Drinks and Risk =
of=20
Esophageal Cancer </B><BR>Carbonated soft drink consumption may be =
associated=20
with a decreased risk of esophageal adenocarcinoma, according to a new =
study.=20
<P>Consumption of soft drinks has been associated with gastroesophageal =
reflux,=20
a recognized risk factor for a specific type of esophageal cancer called =

esophageal adenocarcinoma. Rates of esophageal adenocarcinoma have =
increased=20
markedly since the mid-1970s, as has the rate of soft drink consumption. =
Susan=20
T. Mayne, Ph.D., of Yale University School of Medicine and Yale Cancer =
Center in=20
New Haven, and colleagues studied the association between soft drink =
consumption=20
and risk of esophageal adenocarcinoma in a population of 1095 cancer =
patients=20
and 687 control subjects.=20
<P>The authors found that consumption of carbonated soft drinks or diet =
soft=20
drinks was associated with an unexpected decreased risk of esophageal =
cancer, a=20
finding mainly associated with consumption of diet soft drinks. The =
authors=20
caution that consumers of diet soft drinks may differ from other =
consumers in=20
that they may engage in other unmeasured healthy behaviors. They =
conclude that=20
drinkers of carbonated soft drinks are no more at risk for esophageal=20
adenocarcinoma than the general population.=20

but second primary malignancies among this group account for 16% of all =
cancer=20
incidence. In a commentary, Lois B. Travis, M.D., of the National Cancer =

Institute (NCI) in Bethesda, and colleagues highlight research =
priorities=20
identified at a 2004 NCI workshop called "Cancer Survivorship =96 =
Genetic=20
Susceptibility and Second Primary Cancers." These priorities include =
developing=20
a national research infrastructure for studies of cancer survivorship; =
creating=20
a coordinated system for biospecimen collection; developing new =
technology,=20
bioinformatics, and biomarkers; designing new epidemiologic methods; and =

developing evidence-based practice guidelines.=20
