SAN FRANCISCO (MedPage Today) -- The immunotherapy agent sipuleucel-T (Provenge) appears safe for use earlier in prostate cancer, researchers found.

(University of Copenhagen) Researchers at the University of Copenhagen have explored the active principles of a Danish mushroom and found that some of the substances it contains are particularly toxic towards cancer cells.

The goal is to synthesize and refine substances in the mushroom that may be useful in future drug development.

(MedPage Today) -- Among men who have sex with men, the vaccine against human papillomavirus (HPV) reduces the risk of the precursors of anal cancer, researchers reported.

(MedPage Today) -- Having somewhat elevated levels of certain antibodies seem to protect against at least one form of brain cancer, researchers found.

(Terry Fox Research Institute) Women throughout the world will benefit from a new, pan-Canadian Terry Fox Research Institute initiative that aims to change the way in which ovarian cancer is diagnosed and managed.

Through TFRI leading ovarian cancer researchers and clinicians across Canada have joined forces to develop a "made-in-Canada" solution to this global clinical problem facing cancer doctors.

(Lund University) Prostate cancer that has become resistant to hormone treatment and that does not respond to radiation or chemotherapy requires new methods of treatment.

By attacking stem cell-like cells in prostate cancer, researchers at Lund University are working on a project to develop a new treatment option.

(Thomas Jefferson University) Pancreatic cancer researchers at Thomas Jefferson University have shown, for the first time, that blocking a receptor of a key hormone in the renin-angiotensin system (RAS) reduces cancer cell growth by activating the enzyme AMPK to inhibit fatty acid synthase, the ingredients to support cell division.

(Georgia Health Sciences University) Altering the body's metabolism could be an effective treatment for deadly liver cancer, researchers report.

The finding that inhibiting heat shock transcription factor 1, or HSF1, prevents liver cancer in mice also is another wake-up call that a low-fat, healthy diet is an effective cancer deterrent, said Dr.

Demetrius Moskophidis, Cancer Virologist/Immunologist at Georgia Health Sciences University. HSF1 and its target genes are important to metabolism regulation.

(Helmholtz Association of German Research Centres) A compound that for about 60 years has been used as a drug against tapeworm infection is also apparently effective against colon cancer metastasis, as studies using mice have shown.

The compound silences a gene that triggers the formation of metastases in colon cancer. Researchers in Berlin, Germany, made this discovery in collaboration with researchers in the USA.

Plans are already underway to conduct a clinical trial.

(University Hospitals Case Medical Center) An inadequate amount of sleep has been associated with higher risks of obesity, heart disease, diabetes, and death.

Now colon cancer can be added to the list.In a ground-breaking new study published in the Feb. 15, 2011, issue of the journal Cancer, researchers found that individuals who averaged less than six hours of sleep at night had an almost 50 percent increase in the risk of colorectal adenomas compared with individuals sleeping at least seven hours per night.
