PROSTABLOG NZ:  The PSA test may get a bad rap from epidemiologists and the Ministry of Health, but so far as I’m concerned it’s a winner.

It’s a reliable post-treatment indicator of whether your prostate cancer is coming back or not, and I’ve just had my two-year test – and it remains undetectable.

That’s very good news, so far as I can discern. My reading of things prostate tells me the two-year mark is a crucial one, a time when recurrence is most likely to rear its unwelcome head.

That doesn’t mean I’m cured. There’s a long way to go before that marker, perhaps a decade.

The only thing I’m not sure about is the fact my PSA never registered much (let alone any change) prior to my diagnosis in 2008.

Does that mean post-surgery PSA tests won’t work on me either.

Nah, let’s not dwell on it.

REUTERS: British scientists say they have developed a lab test that can accurately distinguish prostate cancer from healthy tissue and other prostate conditions. READ MORE>

Researchers at a genetics and diagnostics firm Oxford Gene Technology say the set of biological signals, or biomarkers, they have identified was able to distinguish healthy tissue and benign prostate disease from prostate cancer with 90 percent accuracy in initial laboratory sample tests.

A full test for use in doctors’ clinics is likely to be at least five years off, they said, but their pilot study testing around 130 samples showed encouraging results in a disease area where more accurate diagnostic tests are sorely needed.

NEW PROSTATE CANCER INFOLINK: It has been well understood for some time that there is confusion among men in general and among members of the primary care community about appropriate use of PSA testing. READ MORE>

NEW PROSTATE CANCER INFOLINK: The debate about mass screening for prostate cancer has been moved on significantly by by some recent Swedish studies, writes Mike Scott:

Is there a simple take-away from these three Swedish studies that correlates to the data from the meta-analysis of the six major screening trials? We believe that there is, and it is based on a testable premise:

  • All men should get a PSA test every 5 years starting at age 40, each of which is likely to be able to project a 25-year risk for diagnosis of prostate cancer and/or clinically significant prostate cancer.
  • Men who are shown to be at no significant 25-year risk based on these 5-yearly PSA tests may not need to get interim PSA tests unless there are other reasons for them to do so (based on clinical signs and symptoms, ethnicity, genetics, and other known factors).
  • Men who are shown to be at significant 25-year risk based on any one of the 5-yearly PSA tests should be encouraged to monitor their PSA with care over time in consultation with a prostate cancer specialist and make appropriate clinical decisions based on their individual data.

ASSOCIATED PRESS: Screening for prostate cancer will not be included in President Obama’s new preventive health insurance next year. READ MORE>

New health insurance policies beginning on or after September 23 must cover — without charge — preventive care that’s backed up by the best scientific evidence. Most people will see this benefit, part of the Obama administration’s health care overhaul, starting January 1.

The list includes tests strongly recommended by the US Preventive Services Task Force, an independent advisory panel that evaluates research.

Of note for men: Screening for prostate cancer isn’t included on the list because its benefits haven’t been conclusively shown by the best research, at least to the high level required by the law.
