ABOUT PROSTATE CANCER
PCa is diagnosed primarily through a combination of two widely
used
diagnostic tests-Prostate Specific Antigen (PSA) and the Digital Rectal
Exam
(DRE). A PSA of 4.0 ng/mL or less is less suggestive of PCa;
however, the
cutoff value may be dependent on your age. A higher PSA
level by itself
does not necessarily mean that you have PCa, and a lower PSA
level does not
necessarily mean that you don't have PCa. The DRE
enables your doctor to
feel the size, shape, and texture of your prostate to
determine if you have
a clinically important prostate. However, you can
have PCa without having a
palpable tumor, and palpable nodules or
abnormalities are not always PCa.
Other diagnostic tests which your
doctor may perform on a blood or tissue
sample include the PSA II or Free
PSA, which should rule out prostatitis
and/or BPH. The Reverse
Transcriptase-polymerase chain reaction test
(RT-PCR)test, which can
determine the presence of small numbers of PCa
cells; the serum acid
phosphate test, and the alkaline phosphatase test; or
the ProstaScint, which
involves injecting a radioisotope into the
bloodstream
which attaches
itself to the cancer, then using a gamma-ray camera to locate
the PCa, if
any, in your body. None of these tests or procedures are
100%
accurate.
Even though much of the testing is controversial, most
survivors prefer that
newcomers be diagnosed early in the hope that early
diagnosis will give
greater choice of treatment and cure with fewer side or
after effects.
High PSA's may also be the result of BPH, or a urinary
infection, and
although the FDA has approved a number of PSA assays for
monitoring (already
treated) men, the Hybritech Tandem PSA is the only assay
which has had long-
time FDA approval for use as a diagnostic tool. It's
thought of by most
professionals as the most accurate, reproducible PSA assay
available. Know
that NO PSA assay is perfect!
At 57, my own Hybritech PSA was 15, the Gleason was 6, and I was diagnosed as
a T1c. After my Radical Prostatectomy it was upstaged to T2 with a Gleason's grade
of 3+4 for a score of 7
The
results of one or more of these tests, including a suspicious DRE are
Good
cause for a biopsy. If PCa is found in the tissue removed at biopsy,
a
Gleason Score will be assigned. It will be someplace between 2
and
10, the higher number indicating a more aggressive PCa. The Gleason
score
has two components, the GRADE and the SUM. The grade is based on
how the
individual cells look under the microscope. The grades range
from 1 to
5, with 1 being the closest to normal and 5 being bad. There are
both
general and specific guidelines for each grade, but the experience of
the
pathologist is key - which is why a second opinion on the biopsied
tissue
is often a good approach.
When the pathologist reads a
specimen, s/he looks at it to determine the
most common grade of tumor seen:
that is the first number of the Sum Score.
Then the pathologist determines
the next most common tumor area and assigns
a Gleason Grade to it. This is
the second number. The two numbers together
give the sum. Close reading
of the pathology report, will often indicate
both the Grade and the
percentage of each grade, which may make you feel
better or worse than
knowing the GSS (Gleason Sum Score) - but the GSS is
what is reported in most
of the medical literature and used for comparisons.
So a 3+4 means more grade
3 than grade 4 and a 4+3 is just the opposite.
Also a 5+2 means more 5 than
2, etc. A few pathologists feel that if the
scores are not adjacent (like 5
and 2) there is something wrong with either
the sample or the reading and
will often ask for an independent second
opinion. A final note; reviewing
specimens after CHT is even more difficult,
and, should be sent to a
specialist who sees a lot of this
tissue.

PCa is generally treated
by three kinds of doctors: You probably will see a
UROLOGIST first. If the
diagnosis indicates that the cancer has not escaped
the gland, it would be
wise for you to see a RADIATION ONCOLOGIST for
a second opinion. If the
cancer has escaped the gland, a MEDICAL ONCOLOGIST
might be the source of a
second opinion. Some patients seek a medical
oncologist for another opinion
even though the cancer has not escaped
the gland--sort of a "neutral,"
professional opinion. You're lucky to have
found this source of information
before you, friend or relative submitted to
therapy. Even though you may be
"anxious" to "get on with it", you can
postpone treatment for a brief period
until you have done your home work.
You need to know everything about each of
these PCa treatment
modalities:
1.
Proton Beam Radiation
2. Radiated Implants, permanent (often referred to as
"seed
implants", or "SI"), or temporary (often referred to as
"high
dose radiation", or HDR")
3. Three-Dimension Conformal
Therapy
4. Radical
Prostatectomy
5.
Cryosurgery
6.
External Beam Radiation
7. Neutron Radiation
8. Chemo - limited, and highly
experimental
9.
Alternative-Supplemental Treatments,
such
as: Acupuncture, nutritional and/or
herbal
supplements, Essiac & green teas,
Positive
Mental Attitude,
Hyperthermia,
meditation, visualization,
spiritual
healing groups, humor, and lots of
prayer.
10. Combined
Hormonal Therapy (CHT)
Many
medical professionals do not consider CHT
a
cure, but an excellent temporary
measure
which may keep your PCa on hold.
11. Watchful Waiting
A number of therapists are experimenting with
a variety of treatment
combinations, especially CHT with other treatment
modalities. This approach
seems promising, but only time will
tell!
The diagnosis of PCa is almost always accompanied by the FUD
factor--FEAR,
UNCERTAINTY and DOUBT! You can get rid of the FUD factor
by taking charge;
learn all you can learn, so that YOU can decide which
therapy YOU want.
A number of good PCa books have been published. THE PATIENT'S GUIDE
TO PCa by Dr. Mark B.Garnick; and PCa:A NON-SURGICAL PERSPECTIVE by
Dr. Kent Wallner.
Also by: Dr.Patrick C. Walsh, THE PROSTATE A GUIDE FOR MEN AND
THE WOMEN WHO LOVE THEM.
After you've decided on the therapy of YOUR choice, you should seek the most
skilled, experienced practitioner available. Most survivors agree that no
matter what therapy YOU choose, you should do your
homework and be assured
that the contemplated practitioner has done several hundred successful
procedures.
I had my RP done by Joy G. Paul Torrance CA 310-542-0199.
I regained full continence just 21 days after the catheter was removed.
My PSA one year post RP is still <.03. That is as good as it get's. I hope it will remain so.
Other names are Proton Beam Radiation with Dr. Carl Rossi at Loma Linda
Medical Center in California. Others will choose Brachytherapy, and seek the skill
and experience of Drs. Michael Dattoli, in Tampa; Kent Wallner, John Blasko
in Seattle; or Dr. Richard Stock, in NYC.
Dr. Patrick C. Walsh, in Baltimore. Peter Scardino, Herbert LePor in NYC are among the most sought,
experienced and skilled Urological Surgeons in the U.S.
