X-ZELL BlogAre we serious about prostate health?
An estimated 1.1 million men worldwide are diagnosed with the disease every year, some 400,000 die of it. That’s about 45 men every hour, every day. And the numbers are rising.
According to new data by the American Cancer Society, the death toll from prostate cancer is bound to increase 10 per cent year-on-year in 2018 alone. That’s one prostate cancer death every 18 minutes.
In the UK, new figures reveal that 11,819 men died from prostate cancer in 2015 (data released with a time delay) – making it the third most common cause of cancer death after lung and colorectal, even overtaking breast, which resulted in the deaths of 11,442 women.
All these cases result from a disease that is largely treatable when detected early. And yet, that’s exactly where the problems begin – detecting prostate cancer with the tools currently at our disposal is not exactly accurate science.
Why science doesn’t have the answer – yet
He says there is no sufficient evidence to recommend routine screening based on PSA, with doctors at risk of finding low-grade disease and “over-treating” healthy patients that don’t actually need to take action.
The same is true for traditional tissue biopsies. Despite being widely accepted as the ‘gold standard’ for prostate cancer detection, some 25 per cent are false-negatives, which can make it seem like you are healthy, but actually carry the disease. Moreover, in the absence of a solid non-invasive screening tool, another 50 per cent of them are performed on healthy people who don’t have cancer.
That’s not a good track record for a test with side effects ranging from rectal bleeding and infection through to incontinence and impotence.
Even worse, randomised clinical trials (the most thorough form of testing the effectiveness of an assay) have shown that even if tissue biopsies are supported by high-tech imaging technology, chances of finding or missing the disease on the first attempt hardly change.
As a result, a dangerous diagnostic void has formed that may be responsible for the recent rise in prostate cancer incidence around the world – and the bewilderment of a whole generation of urologists.
So what’s next? According to Jamie Bearse, President of US lobby group ZERO, putting a halt on prostate cancer detection in general can’t be the solution. “A drop in cancer diagnosis rates among men means grave consequences for some,” he warns – adding that all efforts should be made to find aggressive forms of the disease when there is still time for treating them. “It just doesn’t add up. Knowing your risk and taking steps to identify aggressive cancers should decrease mortality.”
Do we need a change in perspective?
Many such filters have come and gone over the past decade, yet none of them managed to make a lasting impact on clinical routine.
That doesn’t mean we are out of options, though. Driven by agile biotechnology start-ups that are willing to explore new avenues of thought, research into prostate cancer detection is once again picking up speed.
X-ZELL Inc. is one such pioneering force.
Based out of Sunnyvale, California, and backed by a high-tech research lab in Bangkok, Thailand, we are developing a new assay to end diagnostic deficiencies in prostate cancer detection – and with it thousands of avoidable deaths.
Aptly named X-ZELL Prostate™, our new add-on test may be able to detect aggressive, early-stage cancer cells in small, 10ml blood samples, and has already proven itself in various clinical trials across Southeast Asia (contact us for details). Right now, it is undergoing final clinical valuation for a broad market rollout.
Using cutting-edge technologies such as High-gradient Magnetic Separation and Cryoimmunostaining™, which make cancer cell visible that have been considered virtually undetectable until now, X-ZELL Prostate™ will help physicians filter out low-risk prostate cancer patients so that only those undergo further (potentially risky) testing that really need to.
All that is backed by data from our first studies, which covered more than 140 patients. They demonstrated that we can avoid over 50% of biopsies while hardly ever missing any case of clinically significant cancer in the PSA grey zone.
More than just another test
X-ZELL Prostate™ was designed to navigate that grey zone and help doctors qualify patients for active surveillance or additional testing. As such, it’s more than just another test. Once fully validated, it could be the quality assurance urology has been waiting for and a lifeline for patients that fall through the gaps for fear of over-treatment.
How can X-ZELL Prostate™ make a difference?
X-ZELL Prostate™ is a highly sensitive blood test that allows for Circulating Endothelial Cells (CEC), ultra-rare cells shed directly from the tumor’s own blood vessels, to be detected at miniscule quantities in the blood.
Though CEC are shed from tumors less than 1mm in size (they themselves measure 10-100µm in size), they are shed from earliest stage tumors – allowing us to provide early and accurate cancer detection through our patented technology and detection mechanisms.
And best of all: Research has shown that CEC can help us distinguish between dormant and aggressive disease, meaning X-ZELL Prostate™ will not only be able just find the disease where other tests fail to detect it, but also won’t recommend patients for treatment if the disease won’t affect them anyway.
How come I’ve never heard of X-ZELL Inc.?
We have since finalised various clinical trials throughout Southeast Asia, where our research lab is based, to ensure X-ZELL Prostate™ would not only perform reliably, but do so in a routine clinical setting – ensuring doctors receive results they can actually work with.
As a result, X-ZELL Prostate™ first received approval for use in Thailand and the ASEAN region, but we are working hard to confirm additional global release dates very soon. After all, prostate cancer is quickly becoming a major threat to men’s health worldwide, and with every hour we waste, 45 men die of the disease. Time to step up and take the guesswork out of cancer detection.
