Lost Protein Key to Prostate
Treatment?
Northwestern researchers have found that a protein made in the body
is critical for normal prostate growth regulation and could hold a
key to treating prostate cancer. Researchers Jennifer Doll and
Veronica Stellmach found that mice that lack the protein pigment
epithelium-derived factor (PEDF) develop an enlarged prostate. They
then found little to no PEDF in human prostate cancer tissue samples.
The researchers then examined the effects of PEDF on cultured
prostate cancer cells. They found that PEDF triggered an increased
rate of prostate cancer cell death. To read more, go to

Lifestyle linked to prostate cancer
risk
In a six-year study of 1,117 patients with localised prostate cancer,
researchers from the University of Texas looked at prostate specific
antigen levels, the aggressiveness of the cancer - measured by a
biopsy Gleason score - and the size of the tumour. The researchers
discovered that patients with a high risk of progression were
significantly more likely to be obese, to exercise less than twice a
week and to not undergo annual prostate screening. On the contrary,
those with the lowest risk kept their weight down, undertook regular
exercise and were screened regularly for signs of the disease. "What
we are finding has positive implications for prostate cancer
prevention," according to Dr Mfon Cyrus-David of the university's
department of epidemiology. "It appears to be important that men
maintain a low body mass index, exercise to the point of sweating at
least two times a week, and are screened regularly for prostate
cancer," he says. The researchers emphasise that their conclusions
are preliminary and a follow-up study is needed to validate their
findings.

Thalidomide used in cancer
battle
Controversial drug thalidomide is proving a success helping
scientists in their fight to find a cure for prostate cancer. Around
20 terminally ill men showed signs of improvement on the drug, which
caused a national scandal in the 50s and 60s when thousands of
children were born with horrendous defects, many missing limbs. Now
researchers believe they are well on the way to finding a cure for
the disease which is the biggest cancer killer of men and claims
8,000 lives a year. The team is only the second in the world to use
the drug for prostate cancer - the first in America was unsuccessful
as patients suffered serious side effects because the dose was too
high. The Newcastle team now plan to use it on sufferers at an
earlier stage of disease to see if it will cure them. Lead researcher
Dr Marcus Drake, clinical lecturer in urology at the University of
Newcastle, said: "We are very excited about these findings. "Lung
cancer used to be the biggest killer of men but with smoking rates
going down death rates are going down and prostate cancer has taken
over.

HRT Patches Helping Men With Prostate
Cancer
Hormone replacement patches normally used by menopausal women have
proved an effective treatment for men with advanced prostate cancer.
HRT led to a regression of disease in 20 patients and improved their
quality of life, said researchers who carried out a preliminary study
in London. Prostate cancer is fuelled by the male hormone
testosterone. When the disease spreads doctors try to hold it back by
reducing the impact of the hormone. Hormonal drugs are used to cut
production of testosterone or block its effect, and as a last resort
the testicles are removed. But these treatments have significant side
effects, including hot flushes, impotence, oesteoporosis, anaemia and
breast growth. Oestrogen pills can also reduce testosterone levels
but are too dangerous to use because of the risk of blood clotting.
Doctors at Hammersmith Hospital and Imperial College found that
within three weeks HRT patches reduced testosterone levels in the men
to a point normally achieved by castration. Blood flow was good and
bone density significantly stabilised or increased. Symptoms of the
"andropause" - the male equivalent of the female menopause - were
prevented, and quality of life generally improved. Prostate cancer
generally affects men in their sixties or seventies, but doctors are
seeing increasing numbers of middle-aged patients. It is the second
most common cancer in men, with 24,700 people diagnosed each year in
Britain. Of these, about half will die from the disease.

Power Over Prostate
Men with localised prostate cancer may be able to stop the disease
progressing if they maintain normal weight, exercise strenuously at
least twice a week and have routine screenings, according to the
preliminary findings of a University of Texas M D Anderson Cancer
Centre study which looked at the lifestyle of 1117 men over six
years. Lead author Dr Mfon Cyrus-David says: ``What we are finding
has positive implications for prostate cancer prevention.'' He
stressed the results needed to be validated with a follow-up
study.
Fosamax Type Osteoporosis Drugs Noted to
Cause Serious Eye Problems
Drugs commonly prescribed to osteoporosis and cancer patients may
cause serious inflammation in several regions of the eye in some
patients. Researchers hope the finding will make physicians more
likely to monitor patients for such eye problems as well as prompt
drug companies to add warning labels to their products. Two
medications in a class of drugs called bisphosphonates, which are
often used to increase bone density in patients with osteoporosis,
were found to cause the serious side effects in the eyes of some
patients. The drugs are also prescribed to cancer patients, as lung,
breast or prostate cancer that has spread to the bones can also
decrease bone density. Researchers reviewed thousands of cases in
which patients were prescribed bisphosphonates and tracked 314
patients who also reported eye problems. Although the side effects
were rare and did not occur in most patients, some types of eye
inflammation can lead to vision loss or blindness if left untreated.
Of the patients who reported side effects, close to 100 suffered from
blurred vision. Other problems included pain and swelling.
Researchers noted that the side effects went away when patients
stopped taking the medication. New England Journal Medicine March

The role of endothelin axis in
cancer therapy merits further investigation
According to recent research from the United States, "Collectively,
the endothelins and their receptors-referred to as the endothelin
(ET) axis-have key physiological functions in normal tissue, acting
as modulators of vasomotor tone, tissue differentiation, development,
cell proliferation and hormone production. "Based on new data, the ET
axis also functions in the growth and progression of various tumors,"
wrote J. Nelson and colleagues, University of Pittsburgh, School of
Medicine. The researchers concluded: "Preliminary results from
clinical trials, such as those with atrasentan, an ETA-receptor
antagonist in prostate cancer, are encouraging. The place of
ETA-receptor antagonists in cancer therapy for a range of
malignancies merits further investigation." Nelson and colleagues
published their study in Nature Reviews. Cancer (The endothelin axis:
Emerging role in cancer. Nature Rev Cancer, 2003;3(2):110-116).

Sequence Matters When Using Novel
Agent
An experimental agent that targets a cancer cell's protein shredding
machinery (the proteasome) should be given either before or with
taxane-based chemotherapy drugs, but not after, say researchers at
The University of Texas M. D. Anderson Cancer Center who conducted
laboratory tests using prostate cancer cells. The finding is
important because the new therapy, known as PS-341 (Velcade), will
likely be tried as new treatment for a number of cancers due to its
effectiveness in multiple myeloma, says Christos Papandreou, M.D.,
Ph.D., assistant professor in the department of Genitourinary Medical
Oncology. "It appears PS-341 could become quite a hit as a novel
proteasome inhibitor, a drug that increases the effectiveness of
chemotherapy agents," Papandreou says. "We know that while the
sequence it is used in doesn't matter with certain classes of
chemotherapy drugs, it does with others. Hopefully, future clinical
trials will reflect this new understanding." The findings were
published in the Proceedings for the 2003 Annual Meeting of the

NASA's Solution for Urine Control Could
Help Fighter Pilots Avoid Urinal Bags; New Product Helps Men Stay Dry
Despite Circumstance or Incontinence
Flying faster than the speed of sound in a $23 million F-16, our
fighter pilots have to saturate in a diaper (for women) or take aim
at a urinal-type bag (for men). NASA astronauts have come up with a
better way. Using a product produced by Tampa Bay-based BioDerm Inc.,
the astronauts can stay clean and dry and can go about their tasks.
The External Continence Device (ECD) for men fits only to the tip of
the penis with a special hydrocolloid material. Hydrocolloid is a
skin-friendly material that bonds like a second skin and is typically
used in treating wounds. The ECD seals gently yet very securely and
adheres for approximately 24 hours. Urine immediately flows into a
tube and then a leg bag. Skin stays dry. See www.bioderm-inc.com "Our
customers are NASA astronauts and men with spinal cord injury,
multiple sclerosis, muscular dystrophy, recent surgery or other
medical conditions who want to stay active," said Dr. Dennis Kay, CEO
of BioDerm. "They are traveling salesmen, judges, engineers,
executives and hunters. The product gives them freedom. And we can
help fighter pilots, too."

Inhibitors of Novel Cancer Target
Attack Tumor on Two Fronts-AACR Proceedings Highlight Research of
LPAAT-beta Inhibition By Cell Therapeutics, Inc. in Human Cell
Models
In a plenary minisymposium on intracellular signaling published in
the April 2003 issue of the Proceedings of the Annual Meeting of the
American Association for Cancer Research, Cell Therapeutics, Inc.
presented data on a novel cancer target, LPAAT-beta. The data suggest
that the inhibition of LPAAT-beta may impede the growth of tumors on
two fronts, by restricting the growth of supporting tissues such as
blood vessels and by removing a cofactor essential to tumor cell
growth and proliferation. Existing therapies typically use a single
mechanism to fight cancer, whereas, LPAAT-beta inhibitors appear to
have a dual function. In the published proceedings, CTI highlighted
research on signaling pathways which showed that inhibition of
LPAAT-beta by genetic knockdown with RNAi or with specific inhibitors
of the enzyme leads to tumor cell death through apoptosis. CTI's
research also suggests the enzyme plays an important role in cell
types that are critical in the formation of the support tissues
(stroma) and the abnormal blood vessels which support tumor growth
and provide tumor blood supply. "The discovery of a gene product that
has critical functions in the regulation of the Raf and other
cancer-related pathways as well as in the tissues supporting the
tumor is intriguing and suggests LPAAT-beta inhibition may be
particularly effective in treating cancer where therapies that use
only a single mechanism for fighting cancer have failed," said Jack
W. Singer, M.D. and Research Program Chair of CTI.

Deveopment by Stopping Action of Key Protein
Before this study, scientists had linked use of celecoxib capsules

which the medication acted in cancer cells was unknown. Now,
investigators have found that celecoxib capsules stop a key
transcription factor known as Sp1 from turning on multiple genes in
cancer cells known to be associated with cancer growth. One of those
genes triggers production of vascular endothelial growth factor
(VEGF), the predominant angiogenic factor that leads blood vessels to
grow to feed tumors.

Editor's Warning
Label: I have a test every year. At
60 everything was fine. At 61, my PSA was elevated and I had a
biopsy. No trace of cancer. At 62 it was elevated again. I had
another biopsy, it was in four nodes and I had a Gleason of 3+3. Most
states require a doctor to sign the order to draw blood. In Oregon,
it costs $12 to draw it at the hospital, and $38.00 to send it out to
an outside lab and get results. A Free PSA is another $30,
which, if your PSA is over 4.0 gives you another indicator of
possible cancer. An AMAS blood test indicates whether or not it
has metastasized and cost the drawing fee, an overnight shipping
charge in dry ice (mine was $42 from Oregon to Boston), and $135 for
the actual blood test. I'd say that's pretty cheap. If your under 70
and the medical community tells you that what they can do for you
really won't improve your life or extend it much, and that chances
are you'll die of something else first, get a second opinion.
Alternative Medicine's have positive results. Surgery and radiation
extend most men's lives 10 or more years. And, while men in the
higher risk categories are, in fact, at higher risk, I understand
that less than 10% of the men who die from prostate cancer, not a
painless death, are not in the high risk category. I would recommend
the following: If you're over 40, get a PSA test. If the reading
is between zero and 1, get another test in five years.. If it's
between 1-2, get another one in two years, if it's over 2, get a test
every year. If it's over 4, have some other tests done, like the
PSA Free, before a possible biopsy. And start gathering all the
knowledge you can on your possible options.

Breast Gene Fault Increases Prostate Cancer
Risk
A genetic fault that makes women more susceptible to breast and
ovarian cancer also raises a man's risk of developing prostate
cancer, a British scientist said Wednesday. Dr. Ros Eeles, a medical
geneticist at The Institute of Cancer Research in southern, England,
told a medical conference that men with an inherited defect in the
BRCA 2 gene have a five-to-seven fold increased risk of prostate
cancer than those without the fault. She announced plans to launch a
European-wide study of 500 men who have four or more close relatives
who have developed breast cancer before the age of 60. They may have
inherited the mutation and would be more likely to develop prostate
cancer. "We are trying to see if you can identify a high-risk group
(of men) that you can target for screening," Eeles told the first
annual meeting of the medical charity Cancer Research UK. Forty
percent of early onset, aggressive prostate cancers are linked to
inherited factors. Some are due to alterations in the BRCA 2 gene,
according to Eeles. The trial, which is due to begin in December or
January, will be the among the first to use genetic screening to
target men in this way. "The crucial thing about screening for
prostate cancer is to identify those men with a high risk of an
aggressive form of the disease," Eeles added.

Three Prostate Cancer Monotherapies Provide
Equivalent Relapse-Free Survival
Three monotherapies for treating T1/T2 adenocarcinoma of the prostate
provide similar rates of five-year biochemical relapse-free survival,
suggesting that side effects, not efficacy, should be the main
consideration in selecting a therapy. Dr. Louis Potters, chief of
radiation oncology at Memorial Sloan-Kettering Cancer Center's Mercy
Hospital, New York, United States, and colleagues presented their
findings Sunday at the American Society for Therapeutic Radiology and
Oncology (ASTRO) 44th Annual Meeting, in New Orleans, Louisiana. The
researchers reviewed the biochemical relapse-free survival in 1,866
consecutive patients receiving permanent seed implantation (PI),
external beam radiotherapy (EBRT) to a minimum 70 Gy, or radical
prostatectomy (RP). All patients had clinically localized stage T1/T2
prostate cancer treated between 1992 and 1998. Three and forty eight
of the patients were treated with EBRT, 783 were treated with RP, and
735 were treated PI. Over 90 percent of the patients in each
treatment group were stage T1-T2a, and the rest were T2b. About
three-fourths of the patients in each treatment group had an initial
prostate-specific antigen (PSA) level of 10 ng/ml or less and a
Gleason score of six or less. Median follow-up time was 54 months for
all cases. Biochemical relapse was defined as any detectable PSA
value greater than 0.2 ng/ml for patients receiving RP, or three
consecutive PSA value rises for those receiving EBRT or PI. The
5-year biochemical relapse-free survival rates for cases treated with
PI, EBRT, and RP were 82 percent, 77 percent, and 83 percent,
respectively (p=0.082); the 7-year biochemical relapse-free survival
rates were 74 percent, 77 percent and 79 percent, respectively.
Multivariate analysis identified initial PSA (p<0.001), Gleason
score (p<0.001), and clinical T stage (p=0.035) as independent
predictors of biochemical relapse-free survival. In contrast,
treatment modality, age, and race were not predictors. "We are
encouraged that our results confirmed that of these others mined only
monotherapy so that the results are unencumbered by adjuvant
therapies such as hormones or the addition of radiation," he added.
Dr. Potters continued to say that the treatment decision for a man
with prostate cancer may be better based on side effects rather than
that of biochemical outcome. "Further, the results imply excellent
biochemical control regardless of which therapy is chosen," he
added.

Reduced risk of prostate cancer among

Although diabetes mellitus is associated with an increased risk of
several malignancies, a negative association with prostate cancer is
biologically most plausible. The epidemiologic evidence is, however,
inconsistent, limited and based mostly on small studies. We present

we assessed prostate cancer risk among patients hospitalized for

a small, but significantly decreased risk of prostate cancer among
men who had been hospitalized for diabetes mellitus.

the c-myc gene and human chorionic gonadotropin (hCG), a hormonal
growth factor, both of which have been implicated in the growth of
prostate cancer. NEUGENE antisense inhibition of hCG and c-myc in

Free or Low-Cost cPSA Tests During Prostate
Cancer Awareness Week
Recent research shows that the use of the complexed prostate specific
antigen (cPSA) test results in fewer false indications of prostate
cancer than the traditional PSA test and could help avoid more than
44,000 unnecessary biopsies each year in the U.S. Men being screened
during the 14th annual Prostate Cancer Awareness Week (PCAW),
September 15-21, will have access to this additional form of the
standard PSA blood test. During PCAW, more than 500 hospitals,
clinics and private physicians will provide free or low-cost
screenings to more than 100,000 men nationwide.
Prostate specific antigen (PSA), a protein produced by the cells
in the prostate, has proven to be a useful marker for early detection
of prostate cancer and in monitoring patients for disease progression
and the effects of treatment. However, current PSA testing generates
up to 60% "false positives" because PSA levels can also increase due
to non-cancerous conditions of the prostate which are increasingly
common as men get older. It can also generate "false negatives" since
a significant number of cases of prostate cancer have been found in
men whose PSA was "normal." Much research has focused on ways to
improve the accuracy of PSA testing, and cPSA offers a new weapon in
the fight against prostate cancer.

There's a new Web site for people interested in learning more about
brachytherapy, an internal radiation treatment for different kinds of

of radioactive "seeds" inside the cancerous tissue to attack the
cancer. The treatment often has fewer and less severe side effects
than other therapies, according to the American Brachytherapy Society
(ABS). Currently, brachytherapy is used primarily to treat prostate,
breast and cervical cancers. Other methods of treating these cancers
include surgery, chemotherapy and external beam radiation therapies.

Hal Ackerman's graphic account of his encounter with prostate cancer
in My Generation ($2.95) may make some men cringe, but it also may
send them to their doctor for an exam. Ackerman, 50, opted for
hormone-deprivation therapy _ ``chemical castration'' _ instead of
surgery. ``Not only is the sex drive gone,'' he writes, ``but the
desire for the sex drive is gone. Women whose bodies in the past
would have stimulated longing and desire now generate no more
response than the sight of uncovered furniture.'' That's the
downside. The upside is that Ackerman has been cancer-free for more
than a year after subsequent radiation treatment.
Vasectomy Link to
Prostate Cancer Dismissed
Dr Brian Cox and colleagues from Dunedin School of Medicine,
Wellington School of Medicine and the University of Otago in New
Zealand looked at more than 2,000 men, almost half of whom were newly
diagnosed prostate cancer patients, to examine whether a link between
this cancer and vasectomy existed. New Zealand was considered to be
an ideal country in which to conduct the investigation because of its
high incidence of vasectomy and its mandatory policy on cancer
reporting. The men, aged between 40 and 74, had all been married at
some time and were interviewed via telephone about previous
illnesses, vasectomies, smoking and alcohol consumption, prostate
specific antigen testing, rectal examination, previous urological
symptoms, family history of cancer and socio-demographic
characteristics. The researchers found that there was no increased
risk of the disease among men who had undergone a vasectomy 25 or
more years before they were interviewed. Furthermore, vasectomy
carried no greater risk of prostate cancer, even after adjusting for
social class, geographic location, religion and family history.
"Since vasectomy is so common in New Zealand and all new prostate
cancers there must be reported to its National Cancer Registry,
that's where you would expect to find a link between the two if one
exists," said Dr Steven Kaufman of the National Institute of Child
Health and Human Development's Contraception and Reproductive Health
Branch. He added, "Also, although the study was more than large
enough to detect an increased prostate cancer risk associated with
vasectomy, none was found." The findings appear in the Journal of the
American Medical Association
Modified tomato may protect against
cancer
Scientists in the US have modified a tomato genetically so that it
contains higher than normal levels of a chemical that may offer
protection against cancer. It was developed at Purdue University in
Indiana by accident as scientists sought higher quality strains of
the fruit. Tomatoes contain various antioxidants, including lycopene,
which is associated with reduced cancer risk. The new strain, which
is modified with a yeast-derived gene, contains between two and
three-and-a-half times the lycopene of the average tomato.

Return of Prostate Cancer First Seen by MRI,
Not Biopsy
A study has found that dynamic magnetic resonance imaging (MRI) can
detect prostate cancer recurrence even before it can be detected by
biopsy. The finding was presented at the annual meeting of the
American Roentgen Ray Society in Atlanta (GA, USA). The study,
conducted by researchers at Sapporo Medical University (Sapporo,
Japan), involved 21 patients who had a rising prostate-specific
antigen (PSA) level following radical prostatectomy. All patients had
an ultrasound-guided biopsy that came back negative, but the MR
images in 17 of the 21 patients indicated local recurrence.
Additional biopsies to confirm recurrence would have wasted precious
time, during which patient PSA levels would have continued to rise.
Therefore, the researchers conclude that prostate cancer patients
with a rising PSA following prostatectomy should first have an MRI to
determine if their cancer has returned. "MR is allowing us to detect
the recurrence earlier, when the cancer can be more effectively
treated with radiation therapy," says Miki Takeda, M.D., the lead
author of the study. In fact, 15 of the 17 patients in the study were
treated with radiation therapy, and seven are now considered cancer
free. "Dynamic MR imaging contributed to these results," adds Dr.
Takeda
Prostate Cancer Cell Growth Inhibited by
Red Wine
Studies have suggested that environmental and dietary factors have an
important influence on the development of prostate cancer, as
witnessed by the higher rate of the malignancy among Japanese men
living in the US compared to those in Japan. Mediterranean countries,
where red wine is commonly consumed, have lower rates of prostate
cancer than other western countries. Dr I Romero and colleagues from
Getafe University Medical Centre in Spain investigated five
polyphenols - quercetin, morin, rutin, gallic acid and tannic acid -
found in red wine to determine whether they exerted an effect on the
growth of the LNCaP cell line. LNCaP cells were obtained and cultured
in vitro before each of the five polyphenols was added to separate
dishes and incubated for 96 hours. Rates of proliferation and
apoptosis were assessed using colorimetric and cell-death detection
assays, respectively. The cultures were sampled at 24, 48 and 72
hours, and cell proliferation was also assessed after 96 hours. The
researchers found that 5 and 10mol/l of gallic and tannic acid and
quercetin, and 50 and 75mol/l of morin and rutin, all significantly
reduced rates of cell proliferation compared to control plates. Rates
of apoptosis inhibition varied between polyphenols, with gallic acid,
tannic acid and rutin bringing about significantly greater rates of
cell death compared to controls. The effects of morin were only
observed at 72 hours, and those of quercetin within the first 48
hours. Dr Romero and colleagues conclude that these polyphenols,
which are always present in red wine, significantly inhibit prostate
cell proliferation and activate apoptosis. Writing in the BJU
International, they add, "These results provide a rationale for
studying the in-vivo effects of these nutrients, with the potential
for formulating future recommendations about the intake of these
substances as chemopreventive agents." Reference: Romero et al, BJU

Cancer's Effect on Relationships under
Scrutiny
The study, funded by Cancer Research UK and led by specialist cancer
nurse Lynne Colbourne, will involve 30 patients with either prostate
or testicular cancer and their partners. Ms Colbourne will follow the
couples from diagnosis and assess how survivors feel their lives
changed following successful treatment. The findings should help
nurses and other health professionals give better support to prostate
and testicular cancer patients and their families, says Ms Colbourne.
An earlier, smaller study showed that men who survive testicular
cancer tend to trivialise the event and want to return to normal life
as soon as possible. In contrast, women preferred to discuss what was
happening with their friends - an approach that often caused conflict
within the relationship. "Recovering patients were constantly in fear
of the cancer returning and they found that difficult enough without
taking on board the fear of their partner," says Ms Colbourne.
Patients also found it distressing that when they reported even the
smallest abdominal pain, wives or partners would insist they had it
checked, says Ms Colbourne. Some women said that their husbands had
become short-tempered after cancer treatment and some experienced
sexual difficulties, although cancer had not had a detrimental effect
on the couples' sex lives in the majority of cases. Ms Colbourne's
study will examine in greater depth the different coping strategies
employed by men and women, and what adjustments are made to the
relationship. Jamie Spencer, a 34-year-old quantity surveyor from
Nottingham who was diagnosed with testicular cancer in 1995, says his
experience put a strain on his relationship. "When I was going for
monthly checkups I became very stressed for two weeks beforehand and
then I would be elated for two weeks afterwards," he says. Although
Jamie now feels that he has beaten his cancer, he says his wife
worries that the cancer is returning at the slightest sign of any
illness. According to Cancer Research UK, around 22,800 men are
diagnosed each year with prostate cancer and the majority of cases
occur in men over 70. Testicular cancer is the most common cancer in
men aged between 15 and 45, with around 1,900 cases diagnosed in the
UK each year.
Prostate Tissue Could Treat Bone
Disease
A team from Ohio State University's Comprehensive Cancer Center point
out that, unlike other cancers, when prostate cancer spreads to the
bones it stimulates growth. When most other cancers spread to the
bones, they cause them to crumble, resulting in pain and
debilitation. Dr Tom Rosol, a vet at the centre, says that up till
now it has been difficult to find out why prostate cancer has this
effect on bone because of the problem of finding a suitable animal
model. Whenever scientists put human prostate cells into animals they
behave differently to the way they do in humans, he says. He decided
to test whether healthy prostate tissue, in addition to cancerous
tissue, was capable of sending growth signals to the bone. And he
used dogs' healthy prostate tissue as a means of testing his
hypothesis as they are the only animals, other than humans, that
develop cancer of this gland. Small amounts of prostate tissue
obtained from dogs were inserted under the skin of adult nude mice,
which were observed for two weeks. The results left researchers
"shocked", says Dr Rosol. Within two weeks the density of the
skullcap or calvaria of the mice had almost doubled. "This was really
exciting, not just because of the speed of the reaction, but because
there are really very few things in nature that induce bone growth,"
says Dr Rosol. While he says it is unclear what causes the bone to
form he suggests the probability is that it is a "complex mix of
growth factors", such as a parathyroid hormone-like protein and
endothelin-1, which act alongside receptive agents in the hosts'
bone. His team is currently working with a drug designed to block
endothelin-1 activity and they believe it may be working. Dr Rosol
says that there is a need to develop new and workable animal models
to improve understanding of cancer. But he says that a process such
as prostate cancer metastasis may hold the clue to an effective
treatment for diseases such as osteoporosis that involve bone
destruction. "What is devastating for a prostate cancer patient may
be a source of hope for someone with osteoporosis," adds Dr Rosol.

Limiting PSA Testing To Men with a Family
History of Prostate Cancer "Misses Most Prostate Cancers"
Researchers at the Finnish Cancer Registry in Helsinki say that,
despite some evidence that men with a family history of prostate
cancer are more likely to develop the disease, limiting screening
efforts to these men will result in doctors missing many cases of the
disease. Only six per cent of prostate cancer cases would have been
detected in a study of more than 20,000 men, if testing for prostate
specific antigen (PSA), a protein linked to prostate cancer, was
restricted to men with a family history of the disease. The research
is reported in the Journal of Clinical Oncology.

Dogs Key to Understanding Advanced Prostate
Cancer
When some of the most common cancers spread, they often head for the
bones. Once there, they typically eat away the good, strong tissue,
leaving a soft and crumbly structure in their wake. It is a painful
and debilitating condition. But prostate cancer is different. Unlike
any other cancer, when prostate cancer spreads to the bones - as it
does in 80 percent of all advanced cases - it actually stimulates new
bone to grow, not erodes it.

BYU Study Finds Prognosis Is Worse for
Prostate-Cancer Patients in Their 40s
Prostate cancer's deadly grip is worse for men in their 40s even
though the disease is still considered rare in anyone younger than
50, according to a Utah-led study.
The findings raise more questions than answers, the authors say,
because race and tumor stage made little difference in the poorer
prognosis.
"It may be that younger men diagnosed with prostate cancer have a
more difficult time adjusting to their diagnosis psychologically,"
says the study authors, Ray Merrill and Justin Bird, researchers at
the Provo-based Brigham Young University.
Yet the BYU team, part of the College of Health and Human
Performance, says more research is needed to discover exactly why
prostate-cancer prognosis is worse in the 40-49 age group compared
with the 50-79 group. Men 80 years and older, like the younger group,
also had a poorer prospect of recovery.
The study appears in a recent issue of the journal Cancer Causes
and Control. Data was gathered from nearly 300,000 prostate-cancer
patients in five U.S. states (Utah, Connecticut, Hawaii, Iowa and New
Mexico) and in four major cities (Atlanta, Detroit, San Francisco and
Seattle).
Possibly "sexual potency may be a more important concern for men
of younger ages, and this may deter them from selecting treatment,
influence their treatment choice or delay initiation of treatment,"
the study says.
The disease signals an uncontrolled malignant growth of cells in
the gland located just below the male bladder. In U.S. men, prostate
cancer is the second leading cause of death; it can be diagnosed with
a PSA test of the blood or through a physical exam called digital
rectal exam or DRE.
Controversy surrounds the idea of encouraging prostate screening
in younger men because data, including the BYU study, fails to show
any early diagnostic benefit among the general male population, the
authors said.
The American Cancer Society describes prostate cancer as a latent
disease, hidden but waiting to develop. The group cautions against
raising undue alarm by testing before age 50 unless there is father,
brother, or son diagnosed with prostate cancer at a young age.
New Predictive Marker Found for
Prostate and Colon Cancer
A protein that interacts with the gene for Huntington's disease could
also help physicians diagnose and more effectively treat patients
with two of the most common and deadly forms of cancer, according to
a new University of Michigan study.
Absent in normal prostate and colon epithelial cells, but found in
large amounts in prostate, colon and other tumor cells, it is called
huntingtin interacting protein or HIP1. The protein has never before
been associated with any type of cancer. (Editors: Note "huntingtin"
is correct spelling.)
"Anytime you find a true marker for cancer, it's surprising," says
Theodora S. Ross, M.D., Ph.D., an oncologist in the U-M's
Comprehensive Cancer Center and an assistant professor of internal
medicine in the U-M Medical School. "But HIP1 also is unusual,
because it seems to be such a strong prognosticator, especially for
prostate cancer."
Results of U-M research on HIP1's relationship to human prostate
and colon cancer were published August 1 in the Journal of Clinical
Investigation.
"We don't find significant HIP1 expression in normal prostate
epithelial cells, but as prostate cancer develops and progresses, we
see a steady increase in HIP1 expression," Ross explains. "HIP1 was
expressed in 50 percent of tumors from patients in the earliest
stages of cancer, 88 percent of tumors from patients with localized
prostate cancer, and 100 percent of patients with metastatic prostate
cancer."
"High levels of HIP1 were present in every stage of colon cancer,"
Ross adds. "In melanoma, breast and ovarian cancers, the expression
patterns varied, but HIP1 was consistently over-expressed."
During her post-doctoral fellowship at Boston's Dana-Farber Cancer
Institute, Ross cloned the protein from bone marrow cells of a
patient with leukemia. Since joining the U-M Medical School three
years ago, she has focused on nothing but HIP1 and its relationship
to an important cellular trafficking and signaling system called the
clathrin-mediated trafficking pathway. Cells use this system to
remove old receptors and signaling molecules on cell surfaces and
replace them with new molecules.
The HIP1 protein appears to be involved in this process, according
to Ross, along with another protein called htt, which is expressed by
the mutated gene responsible for Huntington's disease -- an
inherited, progressive form of dementia. Although both proteins are
found in parts of the cell where movement of material occurs, their
exact role is unknown. The connection to the Huntington's gene could
be significant, however, "because people with Huntington's rarely get
cancer," Ross adds.
"This is a new pathway in tumorigenesis; no one else is working
with it in this context," Ross says. "Our paper is the first
demonstration of a connection between tumor formation and a protein
involved in this cell trafficking pathway."
Ross' laboratory is now trying to understand the relationship
between HIP1 and cancer cells. "Originally, I thought HIP1 was a
tumor suppressor gene, but it could be a survival factor that
prevents cancerous cells from dying or an oncogene causing normal
cells to become cancerous. It could have varying effects, depending
on the cell or tissue type. More research is needed to know for
sure," she says.
Results included in the JCI paper showed that when U-M researchers
created a mutant version of HIP1 by knocking off one segment of the
protein, the result was massive cell death. "When we made a mutant
that interfered with the function of the normal protein, the cells
died, which suggests that HIP1 is necessary for cell survival," she
says.
If scientists can discover the functional relationship between
HIP1 and cancer, Ross believes it should be possible to develop
agents that could kill prostate and colon tumor cells without harming
the normal epithelial cells lining the inside of these organs.
In her study, Ross first measured levels of HIP1 expression in 60
cancer cell lines and a tissue microarray of primary tumors from the
National Cancer Institute, which included hundreds of tissue samples
from colon, breast, melanoma, ovarian, prostate, kidney and lung
cancer. "We never could have looked at all these different tumors
without the NCI microarray; it's an amazing resource for
investigators," Ross says.
To quantify HIP1 expression in different stages of prostate
cancer, U-M researchers used tissue samples from the U-M Prostate
Specialized Program of Research Excellence (SPORE) tumor bank, funded
by the National Cancer Institute. Tissue samples of various stages of
colon cancer were provided and interpreted by Peter C. Lucas, M.D.,
Ph.D., U-M lecturer in pathology.
Research on the genetic and molecular profile of prostate cancer
is part of a major initiative underway in the U-M Comprehensive
Cancer Center. Its goal is to link molecular genetics and proteomics
with clinical outcome for all types of cancer.
The research study was funded by the Huntington's Disease Society
of America, the National Institute of General Medical Sciences and
the Cancer Research Fund of the Damon Runyon Foundation.
Dinesh S. Rao, Ph.D., a U-M post-doctoral fellow, is first author
of the study. In addition to Lucas, other U-M Medical School
collaborators include Martin G. Sanda, M.D., associate professor of
surgery and of internal medicine; Mark A. Rubin, M.D., associate
professor of pathology and surgery; Ikuko F. Mizukami, Ph.D.,
research associate; and graduate students Teresa S. Hyun and Priti D.

Winning His Battle
Speaking from his 10th-floor, ocean-side San Diego condo Tuesday,
Jerry Tarkanian was, well, Jerry Tarkanian.
Alert and optimistic, the former Fresno State coach didn't sound
like a 71-year-old in his second week of radiation treatment for
prostate cancer. An all-encompassing conversation roamed from his
health to the latest basketball gossip to books. Yes, books.
"I'm trying to read a book called 'The Trust Fund'," Tarkanian
said. "I used to only read [basketball] books. I'm not like
that anymore."
He didn't even bring any UNLV or Fresno State game tapes to his
Southern California home, where he will spend weekdays for the next
seven weeks recovering from treatment. Each morning, Tarkanian
receives about 15 minutes of treatment at a Scripps medical facility
in San Diego.
Then he retreats to his condo to read and rest.
"I feel good," he said. "After the treatment I get tired and
usually take an afternoon nap. But that's OK."
Tarkanian was warned of potential prostate cancer in August, but
initially didn't worry about it. Then, after the season, he decided
to tend to it while the prostate cancer -- the leading cause of
cancer deaths in men aged 55 or more -- was in the early stages.
Many luminaries in the basketball world have expressed sympathy
for the man who viewed himself as the NCAA's No. 1 target. NBA
personality Charles Barkley wished Tarkanian well on the national TNT
broadcast of the NBA draft after former Fresno State center Melvin
Ely was selected. Adidas bigwig Sonny Vaccaro said last week his
thoughts and prayers were with his friend.
"The treatment is going fine," said son and former Bulldogs
assistant Danny Tarkanian, who now lives in Las Vegas. "Doctors told
him they think it is contained in the prostate. My dad says he is not
feeling any pain."
Asked if he felt apprehension about receiving treatment, Tarkanian
said. "At my age, you expect something [to be wrong with
you]. ... They said they got it early. This is supposed to cure
it."
Tarkanian also said he and his two sons, Danny and George, will
establish a youth basketball academy in Las Vegas. The Tarkanians
will hold camps for elementary school-aged kids this month to raise
money for the academy.
Helping out will be former UNLV players, including Sam Smith,
Robert Smith and Freddie Banks.
Tarkanian has his weekends free to visit relatives and friends. He
said he will be in Fresno in two weeks.
He also said he has plans to attend the Oct. 26 Florida
State-Notre Dame football game in Tallahassee, Fla., with
friends.
"He is doing well," George Tarkanian said. "The treatment is not
really affecting him too much."

Lance Armstrong Inspires Cancer
Patients
Lance Armstrong was diagnosed with testicular cancer at the age of
25. A few days later, he learned the cancer had spread to his brain.
He underwent surgery and chemotherapy. Three years later, he rode a
bicycle more than 2,200 miles to win the Tour de France.
Armstrong insists the cancer was the best thing that ever happened
to him, because it taught him about the strength of the human spirit,
and the love of family and friends. One month after his chemotherapy
ended, he met his wife. Using sperm removed before his surgery, he
and his wife conceived a son, who is now 3 years old.
