New Research: Men with Very Low Testosterone Rarely Get Prostate Cancer

Dear Friend,

Each year more than 170,000 men in the United States are affected by prostate cancer. While the causes remain unknown, studies have found that hormone levels could be a key to prostate cancer treatment.

The Role of Testosterone in Prostate Cancer

Age, ethnicity and genetic mutations are some of the common risk factors for prostate cancer. The male hormone testosterone is known to facilitate cell growth in prostate tumors.

Based on the androgen saturation model, scientists believe that an increase in testosterone levels beyond the saturation point does not cause a corresponding increase in benign or malignant prostate tissue. Until recently, there wasn't enough evidence to confirm or refute the model.

Putting a Theory to the Test

Researchers at the University of Oxford in the United Kingdom reviewed data obtained from more than 19,000 men, of whom approximately one-third had prostate cancer. Subjects were grouped into 10 categories ranging from lowest to highest levels of testosterone.

When prostate cancer risk was calculated based on conditional logistic regression methods, men in the lowest group were determined to be 20 percent less likely to develop the disease. Subjects in the other nine groups showed no link to prostate cancer risk.

According to Prof. Tim Key, co-author of the study, this is the first population study to support the commonly-held theory regarding testosterone and prostate cancer. Experts believe it could be a significant step toward more efficient diagnosis and treatment.

New Blood Tests Helps Identify Which Medications Are Best for Prostate Cancer Treatment

Prostate cancer cells with BRCA mutations use a specific enzyme to repair themselves, making tumors resistant to treatment. Drugs called Parp inhibitors block these enzymes, causing cancer cells to die off. These new blood tests help to identify patients who are most likely to respond to Parp inhibitors as part of their cancer treatment.

Genetic Advances Made in Prostate Cancer Identification

A cross-disciplinary team supported by the Prostate Cancer Foundation discovered a gene known as N-Myc that appears to be the driver behind the change to the more aggressive form of prostate cancer. This discovery may lead to more targeted treatments.
