Accurate diagnosis of prostate cancer with ultrasound
By Dross at 2010-12-09 02:24
 

Prostate cancer is the most common type of cancer among men, but its diagnosis has up to now been inaccurate and unpleasant. Researchers at Eindhoven University of Technology (TU/e), in cooperation with AMC Amsterdam, have developed an imaging technology that can accurately identify tumors. The technology is based on ultrasound, and also has the potential to assess how aggressive tumors are. This can lead to better and more appropriate treatment, and to cost savings in health care.

Genetic mutations associated with increased PSA and prostate cancer
By Dross at 2010-12-04 01:49
 

 

Austrian researchers have uncovered mutations throughout the mitochondrial genome that are associated with prostate cancer. An exciting aspect of the study, published by Cell Press on December 2 in the American Journal of Human Genetics, is the association of tRNA mutations with elevated levels of prostate-specific antigen (PSA) in Austrian men diagnosed with various stages of prostate cancer.

How prostate cancer packs a punch
By Dross at 2010-07-14 03:43
 

LA JOLLA, Calif., July 12, 2010 – Some types of prostate tumors are more aggressive and more likely to metastasize than others. Nearly one-third of these aggressive tumors contain a small nest of especially dangerous cells known as neuroendocrine-type cells. More rarely, some aggressive prostate tumors are made up entirely of neuroendocrine-type cells. The presence of neuroendocrine-type cancer cells is associated with a poor prognosis, but spotting these rare cells can be like finding a needle in a haystack.

Cryotherapy: A Novel Treatment Option for Prostate Cancer
By Dross at 2008-08-13 21:05
 

Each year nearly 33,000 men in the UK are diagnosed with prostate cancer and more than 10,000 die from the disease. It has become the most common cancer in men and mainly affects men over the age of 50. People affected and their families should be informed about all the options available to them - cryotherapyterm is one such treatment option.

Cryotherapy is based on the science of freezing at very cold temperatures to kill cancerous cells. This minimally invasive, non-surgical and non-radiation treatment freezes and destroys tumours. The treatment is performed by inserting very fine sealed needles directly into the tumours, through which Argon gas is circulated to reach sub-zero temperatures.

Study raises questions about certain prostate cancer therapies under development
By Dross at 2008-05-01 23:18
 

SEATTLE – Therapies under development to treat prostate cancer by inhibiting the ability of insulin-like growth factor (IGF-1) to activate its target receptor could have unexpected results especially if a major tumor suppressor gene – p53 – is already compromised, according to new research by investigators at Fred Hutchinson Cancer Research Center.

IGF-1 is a polypeptide hormone that can influence growth, differentiation and survival of cells expressing the type 1 receptor (IGF-1R). Past clinical, epidemiological and experimental studies have strongly implicated IGF-1 as a contributing factor in the natural history of prostate cancer. However, very little has been done to prove absolutely that the expression or activation of the IGF-1 signaling pathway at physiologically relevant levels is sufficient to cause a healthy prostate cell to become a cancer cell.

Soy compound may halt spread of prostate cancer
By admin at 2008-03-14 19:42
 

PHILADELPHIA – A compound found in soybeans almost completely prevented the spread of human prostate cancer in mice, according to a study published in the March 15 issue of Cancer Research, a journal of the American Association for Cancer Research.

Researchers say that the amount of the chemical, an antioxidant known as genistein, used in the experiments was no higher than what a human would eat in a soybean-rich diet.

Investigators from Northwestern University found that genistein decreased metastasistermterm of prostate cancer to the lungs by 96 percent compared with mice that did not eat the compound in their chow - making the study the first to demonstrate genistein can stop prostate cancer metastasis in a living organism.

OHSU Cancer Institute research gives hope for chemo holidays for men with advanced prostate cancer
By Dross at 2008-02-26 00:48
 

PORTLAND, Ore. – Oregon Health & Science University Cancer Institute researchers, in a first-of-its-kind study, have found that even men with advanced prostate cancer can take a much-needed safe break, or holiday, from chemotherapyterm.

The double-blind, randomized study, led by principal investigator Tomasz Beer, M.D., recently was published in the journal Cancer. Beer is the Grover C. Bagby Endowed Chair for Cancer Research, director of the OHSU Cancer Institute Prostate Cancer Program, and associate professor of medicine (hematology/medical oncology), OHSU School of Medicine.

Beer and his team wanted to know if men with metastaticterm, androgen-independent prostate cancer cancer that has spread from the prostate and is not affected by the male hormone, androgen could take a break from docetaxel, an intravenous chemotherapy delivery drug that is the gold standard treatment for androgen-independent prostate cancer. Docetaxel works by killing cancer cells and slowing cell growth. However, the drug also can cause side effectsterm, such as hair loss, nausea, loss of appetite and increased chance for infections. Chemo holidays can be a much-needed vacation from these side effects.
