Like most killers, prostate cancer leaves fingerprints. Every malignant cell has its own pattern of active genes and proteins that spells the difference between benign, localized or metastatic tumors.
Microscopic Cantilever Aids Assay For Prostate Cancer
A clever technique for detecting proteins by inducing them to stick to and bend a microscopic cantilever -- essentially a diving board the size of a hair -- is sensitive enough to serve as a diagnostic assay for the protein markers characteristic of prostate cancer, a team of scientists report this week in the journal Nature Biotechnology.
Second Opinion Valuable In Prostate, Bladder Cancer
A new University of Florida study shows that seeking a second opinion after a diagnosis of prostate or bladder cancer can sometimes spell the difference between radical surgery or more conservative treatment -- even watchful waiting.
Anti-Cancer Mushroom Toxin Gets FDA Fast-Track Status
A novel anti-cancer compound was synthesized by scientists at the University of California, San Diego, more than a decade ago from toxins of the poisonous jack-o-lantern mushroom.
UCLA's First-Of-Its-Kind Study Of Urologic Diseases

associated with a lower risk of developing prostate cancer than
is alpha-tocopherol, the synthetic form of vitamin E most
commonly found in supplements.
Cancer Screening Should Start At Age 50-55
New estimates of the lifetime risk of developing
colorectal cancer published in the Journal of Medical
Screening, a BMJ publication, suggest that screening
should start at age 50 or 55 in the general population.
Anti-Cancer Drug Moving To Phase III Trials
Lorus Therapeutics Inc. reported today that the
promising results of Phase II clinical trials of its lead
anti-cancer drug Virulizin(R) will be presented at the 23rd
Chemotherapy Foundation Symposium, titled Innovative Cancer
Therapy for Tomorrow, in New York on November 8.
Toxin's Course Toward Precancerous Lesion
Lung cancer is currently the leading cause of cancer
death in the United States and other developed countries. About
80 percent of patients diagnosed with lung cancer die within 12
months because this type of cancer is silent in its early years
and so is usually not detected until it has reached an advanced
Hopkins To Study Alternative Medicine For Cancer
Can tart cherries alleviate cancer pain? Does prayer
help heal African-American women with breast cancer?
Approach To PSA Testing Could Be Improved
The standard, widely-used approach to screen men for
prostate cancer --annual PSA tests after age 50 -- may be less
efficient and cost-effective than one that tests men earlier and
less frequently, according to a study in today's Journal of
the American Medical Association (JAMA).
Plus AST Seen As Best For Prostate Cancer
In the first study of its kind, researchers at Brigham
and Women's Hospital (BWH) and Dana-Farber Cancer Institute (DFCI)
have found that combined radiation therapy (RT) and androgen
suppression therapy (AST) is a more effective treatment for
localized early-stage prostate cancer compared to treatment
using radiation therapy alone.
Getting Better For Men With Prostate Cancer
This year, about 170,000 American men will learn they
have prostate cancer. Because there are usually no symptoms in
the early stages of the disease, regular check-ups and early
detection are the best weapons against this leading cause of
cancer in men.
On Molecular Sites For Cancer Therapy
Roswell Park Cancer Institute
(RPCI) will host a
symposium titled, "Molecular Sites of Intervention for
Cancer Therapeutics," October 12-13, in the Hilleboe
Auditorium Research Studies Center at RPCI in Buffalo, NY.
Could Be Reversible Key To Cancer
Researchers have found the process that turns a key
tumor-suppressor gene off in people with lung cancer. The
finding may lead to improved prevention of many kinds of cancer.
Gene Therapy Potent Against Advanced Prostate Cancer
Researchers at UCLA's Jonsson Cancer Center have shown for the first time that immunotherapy delivered via gene therapy may prove to be a potent weapon in the fight against locally advanced prostate cancer, according to an article published Sunday (May 20) in the peer-reviewed journal
Human Gene Therapy.
PSA Test Separates Benign From Malignant Prostate
The free PSA
(fPSA) test is significantly better at
distinguishing prostate cancer from benign prostatic conditions
than more traditional follow-up methods used to improve PSA
testing, according to a major new study to be published in the
August issue of Urology.
Reporters Track Gene Therapy In Body
Scientists at UCLA's Jonsson Cancer Center have
discovered a novel way to follow gene therapy through the body:
A tracking system of "reporter" genes that can be
attached to any gene therapy and used to monitor the therapy's
Algorithm For Detecting Prostate Cancer Earlier
A new computerized method for detecting prostate cancer
may lead to earlier detection and eliminate unnecessary
biopsies. The findings will be presented Thursday at the 52nd
Annual Meeting of the American Association for Clinical
Family Of Genes For Malignancy Discovered
A Johns Hopkins research team has discovered a new

level is, the more likely his prostate will continue to grow
abnormally, researchers at UT Southwestern Medical Center at
III Trials Of Prostate Cancer Vaccine Launched
Approximately 240 men with advanced prostate cancer
will be recruited for Phase III trials of a prostate cancer
vaccine. The first trial will be at clinical sites in Western
states. A second Phase III trial, slated to begin during the
next quarter, will take place at clinical sites in the Midwest
Of Prostatectomy Best With Experienced Surgeon
Many men with prostate cancer may endanger their lives
by avoiding prostate removal, unwilling to deal with the
surgery's reported side effects. Now, in a study reported in the
January issue of Urology, Johns Hopkins researchers
conclude that when patients seek out a surgeon highly
experienced in the procedure, they are far more likely to remain
continent and potent than if their operations were done by a
less experienced doctor.
