The limits of observational data in determining outcomes from cancer therapy

Certain biases may exist in observational studies that compare outcomes of different cancer therapies, making the results questionable.

Lipitor and Celebrex combined may halt prostate cancer

Researchers at Rutgers' Ernest Mario School of Pharmacy have shown that administering a combination of the widely used drugs Celebrex (celecoxib, a nonsteroidal anti-inflammatory drug) and Lipitor (atorvastatin, a cholesterol lowering drug) stops the transition of early prostate cancer to its more aggressive and potentially fatal stage.

Cancer prevention

Tapping into a growing body of knowledge about the origins and progression of cancer, researchers are now developing and testing new preventive therapies to stop it in its tracks.

Medicare reimbursement changes likely influenced changes in prostate cancer treatment

Financial pressures from Medicare reimbursement changes may have caused physicians to switch from providing hormonal-induced castration to providing surgical castration for men with prostate cancer.

Healthy male reproductive organs depend on early hormone activity

A discovery by Medical Research Council scientists looking at the development of male foetuses could help explain the origin of common genital disorders that can cause reproductive problems or increase risk of low sperm counts and possibly testicular cancer later in life.

Blocking a signaling protein kills prostate cancer cells

Researchers at Jefferson's Kimmel Cancer Center in Philadelphia have shown that they can effectively kill prostate cancer cells in both the laboratory and in experimental animal models by blocking a signaling protein that is key to the cancer's growth.

OHSU Cancer Institute research gives hope for chemo holidays for men with advanced prostate cancer

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 chemotherapy.

Women with hgher levels of DHEAS have better cognitive function

Women with naturally higher levels of the hormone precursor DHEAS were found to have better cognitive function than women with lower levels, according to a new study appearing in the March issue of the Journal of Clinical Endocrinology & Metabolism (JCEM).

Female-to-male transsexuals have higher androgen levels, not polycystic ovary syndrome

Contrary to previous studies, female-to-male transsexuals do not have a higher prevalence of polycystic ovary syndrome (PCOS), though they do have significantly higher androgen levels, according to a new study accepted for publication in the Journal of Clinical Endocrinology & Metabolism (JCEM).

Hormone refractory prostate cancers more likely to spread to other organs

Prostate cancers that are resistant to androgen deprivation therapy are more invasive and more likely to spread to other organs than androgen dependent prostate cancers, UCLA cancer researchers have found.

Treatment with hormone suppression therapy and radiation improves survival for certain prostate cancer patients

Men with localized prostate cancer who were treated with male hormone suppression therapy and radiation treatment had longer survival, but those with moderate to high levels of other illnesses did not experience this effect, according to a study in the January 23 issue of JAMA: The Journal of the American Medical Association.

Cancer stem cell marker also drives transcription in normal cells

New research links the recently discovered function of a multi-faceted transcriptional complex to control of gene expression in both normal cells and cancer stem cells.

Gender differences in liver cancer

A fundamental difference in the way males and females respond to chronic liver disease at the genetic level helps explain why men are more prone to liver cancer, according to MIT researchers.

Hormonal nutritional supplements might speed prostate cancer progression

Hormonal components in over-the-counter dietary supplements may promote the progression of prostate cancer and decrease the effectiveness of anti-cancer drugs, researchers at UT Southwestern Medical Center have discovered.

Testosterone levels may affect men's cognitive performance

When we think about the powers of testosterone, we usually do not consider mental processes.

Benefits of short-term hormonal therapy for men receiving radiation therapy for prostate cancer far outweigh the risks

Researchers report that just four months of hormonal therapy before and with standard external beam radiation therapy slowed cancer growth by as much as eight years - especially the development of bone metastases - and increased survival in older men with potentially aggressive prostate cancer.

New drug target for treatment-resistant prostate cancer

Scientists at Jefferson's Kimmel Cancer Center in Philadelphia have found that a signaling protein that is key to prostate cancer cell growth is turned on in nearly all recurrent prostate cancers that are resistant to hormone therapy.
