Survey finds alarming rates of shared decision making for prostate cancer screening

A new study finds that while a blood test that helps to screen for prostate cancer remains common, only 30 percent of men in a large national survey reported having a balanced discussion of the advantages and disadvantages of the screening with their doctor.

New genetic test may give men better view on how to deal with prostate cancer risk

Scientists are reporting a test which can predict which patients are most at risk from aggressive prostate cancer, and whether they suffer an increased chance of treatment failure.

Early diagnosis does not necessarily result in longer life, study of cancer screenings shows

Physicians and patients like to believe that early detection of cancer extends life, and quality of life. If a cancer is present, you want to know early, right?

Taking prostate cancer drug with low-fat breakfast can be effective and less expensive, study finds

Taking one-fourth the standard dose of a widely used drug for prostate cancer with a low-fat breakfast can be as effective - and four times less expensive - as taking the standard dose as recommended: on an empty stomach.

Precision-medicine approach could improve accuracy of PSA-based prostate cancer screening tests

A new study led by researchers at UC San Francisco and Kaiser Permanente has identified genetic predictors of normal prostate-specific antigen (PSA) levels in healthy men, which could be used to improve the accuracy of PSA-based prostate cancer screening tests.

New PET radiotracer effectively detects early and advanced stages of prostate cancer

In the featured article from the February 2017 issue of the Journal of Nuclear Medicine, researchers document the first-in-human application of a new imaging agent to help find prostate cancer in both early and advanced stages and plan treatment.

A quarter of men could safely avoid prostate biopsy if MRI is used

Performing an MRI scan of men with suspected prostate cancer could spare a quarter of men from having to undergo prostate biopsy, according to a study published in The Lancet.

Targeted alpha therapy shows promise in treatment of metastatic prostate cancer

Nearly three years of research have brought about remarkable results for the majority of 80 patients subjected to targeted alpha therapy of metastatic prostate cancer.

Study shows the use of Renishaw inVia™ microscope in prostate cancer detection

New research at the Guangdong Medical University suggests a laser-based approach could be the latest breakthrough in prostate cancer detection. The proposed non-invasive blood test uses a combination of two techniques: surface-enhanced Raman scattering (SERS) and a new mathematical analysis technique called support vector machine (SVM).

PITX2 methylation biomarker shows promise for predicting prostate cancer recurrence risk

Prostate-specific antigen (PSA) and other biomarkers are essential tools for diagnosing and monitoring prostate cancer.

Novel imaging technique shows promise to detect, monitor and guide therapy for prostate cancer

An international group of researchers report success in mice of a method of using positron emission tomography scans to track, in real time, an antibody targeting a hormone receptor pathway specifically involved in prostate cancer.

Crowdsourcing new prediction tool for better prognosis of metastatic castration-resistant prostate cancer

Knowing the likely course of cancer can influence treatment decisions. Now a new prediction model published today in Lancet Oncology offers a more accurate prognosis for a patient's metastatic castration-resistant prostate cancer.

Study questions recommendation against PSA screening

Since the U.S Preventative Services Task Force recommended against prostate-specific antigen (PSA) screening for prostate cancer, there has been a significant decrease in the number of prostate biopsies and prostate cancer surgeries across the nation, report researchers.

Risk and reality do not always match up in prostate cancer biopsies, research suggests

When it comes to prostate cancer biopsies, risk and reality don't always match up, according to research published online today in the Journal of Clinical Oncology.

Revised prostate cancer guidelines did not reduce usage of PSA tests, study finds

Controversy over prostate cancer screening guidelines that discourage use of PSA tests did not significantly reduce use of the test, a five-year review of more than 275,000 visits at UT Southwestern Medical Center showed.

C-11 choline PET and MRI help physicians map patterns of prostate cancer recurrence after surgery

A team of Mayo Clinic researchers has, for the first time, successfully mapped patterns of prostate cancer recurrence, following surgery. Using C-11 choline PET imaging and multiparametric MRI, researchers found an anatomically diverse pattern of recurrence, which may help optimize treatment of patients whose prostate cancer returns after surgery.

Intermediate risk prostate cancer patients can achieve survival benefit with brachytherapy alone

For men with intermediate risk prostate cancer, radiation treatment with brachytherapy alone can result in similar cancer control with fewer long-term side effects, when compared to more aggressive treatment that combines brachytherapy with external beam therapy (EBT), according to research presented today at the 58th Annual Meeting the American Society for Radiation Oncology.

Researchers identify, validate three distinct molecular subtypes of prostate cancer

In the largest study of its kind to date, researchers have identified and validated three distinct molecular subtypes of prostate cancer that correlate with distant metastasis-free survival and can assist in future research to determine how patients will respond to treatment, according to research presented today at the 58th Annual Meeting of the American Society for Radiation Oncology.

PSA failure linked to increased risk of death among healthy men

A new study by investigators at Brigham and Women's Hospital has found that a rise in prostate-specific antigen (PSA) levels in healthy men who have previously been treated for prostate cancer is significantly associated with a 1.6-fold increased risk of death.
