Physicians recommend that, starting at
45, men should have an annual prophylactic digital-rectal examination,
a urinalysis, a sonography of the bladder and kidneys and have
their PSA level checked. PSA, which stands for "prostate-specific
antigen," has become the most important marker in urology.
However, an elevated PSA level can - but must not necessarily
- indicate a prostate tumor.
If the suspicion of a prostatic carcinoma is substantiated, the
concept at the Heidelberg Prostate Therapy Clinic is to employ
special, non-invasive methods of examination. This enables a large
number of unnecessary prostate biopsies to be avoided.
Approach without biopsies
However, the accuracy of a prostate biopsy is relatively low and
is associated with clear risks. It often takes three or more punch
biopsies, in which up to 30 samples are taken from the prostate,
to diagnose prostate cancer. In doing so, it may cause bacteria
to flow into the bloodstream, which can also cause life-threatening
blood poisoning.
State-of-the-art laboratory methods enable
the urine expressate (expressed by manipulation of the prostate)
to be analysed by investigating the prostate cells excreted with
the urine.
With this test, we are able to determine if
gene sequences that are typical for cancer cells, in this
case the PCA-3 gene, are active on the prostate cells.
This makes it possible to assess the risk of prostate cancer far
more clearly than by using the PSA level alone.
In addition, early detection in prostate cancer ultrasound diagnostics
has markedly improved.

Using real-time elastography,
tumor-typical solidifications that occur in cancerous tissue changes
can be made visible long before they can be detected via digital-rectal
examination. Tumor localization and the extent of the cancer can
therefore also be assessed very early on. We have been using this
ultrasound diagnostic procedure in the Clinic for Prostate Therapy
since February 2008.
If these examinations lead to increased indications of prostate
cancer, we confirm the diagnosis by performing a precise cell
analysis, which is also carried out without a biopsy, through
cell apheresis.
In the event that these investigations yield
results that reinforce the suspicion of prostate carcinoma, the
further diagnosis can be performed using high-resolution MRT imaging
techniques. The finding can be confirmed by the histological examination
of a single tissue sample, one that is taken not via the intestine,
but instead via the skin.
Also the choline PET CT method of examination can render the tumour-typical
metabolism in the tissue visible.
With the choline-PET-CT examination, the metabolism typical
of tumors can be made visible in the tissue. In addition, extremely
precise diagnostics can be performed to determine the spread of
any cancerous tissue, which then determines the further strategy
for therapy.

Therefore, with the help of these examinations,
we are often able to avoid biopsies, and the information is far
more comprehensive so that organ-saving prostate cancer therapy
is possible in individual cases using high-intensity ultrasound
(=> HIFU).
