Prostate Cancer: A Success Story
Prostate cancer is the most common cancer in
human beings. That is, even though prostate cancer occurs
only in men, the number of men with prostate cancer exceeds the
combined numbers of men and women with any other type of cancer.
For example, there are more men with prostate cancer than the combined
number of men and women with lung cancer or colon cancer. There are more
men with prostate cancer than women with breast cancer.
Prostate cancer is the second most common cause of cancer death
in men. Therefore, not only is prostate cancer extremely
common, it is a fatal illness for thousands of American men yearly.
... [the] inaccurate
notion that prostate cancer is a harmless old man's disease has
been dispelled ...
The formerly popular but inaccurate
notion that prostate cancer is a harmless old man's disease has
been dispelled, at least for the majority of enlightened
physicians. There were two main reasons for the old erroneous
view of prostate cancer. First, as late as the mid 20th-century, the life span of
the average American man was significantly shorter than it is presently.
Many men with prostate cancer died at a younger age of of heart
disease.
Secondly, prostate cancer screening methods
including PSA blood testing now allow the diagnosis of prostate cancer
4-5 years earlier than before. Therefore, physicians recognized that prostate
cancer often grows slowly. Recognition of this fact may have given rise to the false impression that treatment
might not
be required. At first glance,
this information might seem to support the false conclusion that prostate
cancer is a harmless disease. However, when the facts are
examined more closely another reality becomes clear.
Contrary to the notion that prostate cancer is
harmless, the above two reasons support
the very logical opposite conclusion that prostate cancer indeed is a dangerous
disease. Men now live longer, thanks to
advances in medicine such as cardiac surgery, cardiac stents,
cholesterol medications, other cancer treatments, antibiotics
and the like. Since men now live longer they now have both a
greater chance of developing prostate cancer, as well as a greater chance of suffering the ill effects of the disease,
including death from prostate cancer. In the time after
the widespread use of effective treatment for heart disease and before
prostate cancer screening became widely practiced, the
population aged while the complications of prostate cancer became more evident. However, prostate cancer
screening efforts, including PSA testing, now allow the detection of
prostate cancer at an earlier stage thus allowing for cure of prostate cancer using modern techniques.
Therefore, the notion that prostate cancer screening
has shown prostate cancer to be a benign
disease is absolutely false. To the contrary, cancer detection
through prostate cancer screening allows the detection of an
earlier stage of cancer
at an earlier point in the lives of men who, because of advances
in this and other fields of medicine, now have a longer life
expectancies. Obviously,
detection of cancer at an early stage increases the odds of
curing cancer with treatment. Therefore, the preponderance
of evidence suggests that without prostate cancer screening, the harmful effects of prostate cancer
should increase as men live longer. However, thanks to prostate cancer screening
efforts, the disease is
now commonly detected early and cured with treatment.
... prostate
cancer screening and early treatment save lives!
These facts have been borne out by several
observations including published prostate cancer screening
studies demonstrating a decreased incidence of advanced prostate
cancer, confirming the early detection theory, and decreased
mortality rates (decreased death rates from prostate cancer).
Additionally, population based studies have demonstrated
decreased mortality rates from prostate cancer in large groups
of men who have undergone screening. While the cynic presumes that men should not be treated for prostate
cancer, enlightened physicians look at
this data from recent randomized clinical trials and see that prostate cancer is a malignant
condition and prostate cancer screening and early treatment save lives!
...
multiple studies examining the quality of life after prostate
cancer treatment indicate excellent results of treatment.
Cynics also formerly complained that prostate
cancer screening should not be performed because the early
detection of prostate cancer resulted in too many men undergoing
unnecessary cancer treatment. Skeptics
have implied that the treatment for prostate cancer was worse
than the cancer itself. The facts do not bear this out.
In fact, multiple studies examining the quality of life after
prostate cancer treatment indicate excellent results of
treatment. The studies indicate that there is little if
any quality of life change after treatment. Additionally, most men emotionally benefit from treatment by
knowing that they no longer have cancer! In recent years
as prostate cancer has become diagnosed earlier in the course of
the disease, the complication rates of treatment have likewise
decreased. The ultimate
proof of the benefit of early cancer detection and treatment is
a decreased complication rate and death
rate from prostate cancer, combined with preserved quality of
life after treatment. These are the facts!
... selenium
and vitamin E supplementation may be beneficial in preventing
prostate cancer.
The incidence of prostate cancer diagnosis is
about one of every one hundred men in their 40s and 50's and
about one of every eight men in their 60s and 70s. There is a
greater likelihood of being diagnosed with prostate cancer in
men with family histories of prostate cancer. For a man
having two relatives with prostate cancer, the risk of being
diagnosed with prostate cancer is about five times the risk of
the average man. Clearly, there is a genetic
predisposition for the development of prostate cancer and
prostate cancer runs in families. Additionally,
African-American men may have a increased incidence of prostate
cancer.
High-fat diets and diets low in the mineral selenium may
contribute to the development of prostate cancer. Some
studies have also suggested that selenium and vitamin E
supplementation may be beneficial in preventing prostate cancer.
Prostate specific antigen (PSA) is a protein
enzyme found in the prostate, in urine and in the blood
stream of men with prostate glands. As the name implies,
PSA is prostate specific but not specific for prostate cancer.
Testing prostate and urinary PSA has not proven
useful. However, studies have shown that bloodstream PSA
is often elevated in men with prostate cancer. Doctors
have more experience with the use of this blood test than with
the use of any other cancer detecting blood test. PSA is
used both for prostate cancer screening and prostate cancer
follow-up testing. In fact, when men undergo prostate
cancer screening including PSA testing in successive years,
detected cancers are usually smaller and more amenable to
treatment for cure.
... a man with
an elevated PSA is twice as likely to have cancer as a woman
with an abnormal mammogram.
PSA is an effective screening tool for prostate
cancer. In fact, a man with an elevated PSA is twice as
likely to have cancer as a woman with an abnormal mammogram. On average, PSA
allows the detection of prostate cancer some 4-5 years before
the cancer could otherwise have been detected. When men are
tested at the recommended ages for cancer screening, PSA testing
often allows the detection of prostate cancer while the cancer is
still confined to the prostate gland. At this early stage,
prostate cancer is more often curable. Without PSA testing, however,
prostate cancer is often detected only after it has spread
beyond the confines of the prostate, making cure of the cancer
practically impossible.
Many urology specialists believe that normal PSA
values depend on the age of the patient. Commonly used
abnormal PSA ranges are as follows: (1) men in their 40s -- > 2.5, (2)
men in their 50s -- > 3.5, (3) men 60 or older -- > 4.0.
Some say that men 70 or older may have PSA values up to 6.5.
Other experts feel that no man should have a serum PSA > 2.5.
Obviously, there is no exact range of normal that perfectly
discriminates between a man who has prostate cancer and a man
who does not.
... a better way of using PSA
to screen for prostate cancer is ... PSA velocity.
A better way of using PSA to screen for
prostate cancer is monitoring of repeated PSA blood tests
perhaps every 6, 12 or 24 months (depending on the clinical
situation) so that new PSA values may be compared
with established PSA values for the same patient over time. This form of assessment is sometimes
called PSA velocity. Determination of the rate of increase
in serum PSA may be an even more useful means of early detection
of prostate cancer. Using PSA velocity assessment prostate
biopsies may used to detect prostate cancer even when the total
PSA value is in the normal range. Some 25 percent of
prostate cancers are detected when the total PSA value is
normal.
Another effective method for PSA prostate cancer
screening is the determination of a portion of total blood PSA
that his not protein-bound. This so-called "free" PSA
ratio ideally should be greater than 25 percent in men with total PSA values between 4 and 10. Determination of
free PSA ratio and may be best suited for men with elevated
total PSA values having undergone prior negative prostate
biopsies. In such cases, an abnormal free PSA ratio may
guide the urologist to perform additional biopsies.
Interestingly, it has been shown that decreasing free PSA is the
first sign of prostate cancer, occurring up to 5 years before
the total PSA increases.
PSA is not a perfect test for the detection of
prostate cancer. There are no perfect tests in medicine.
Some men with elevated PSA values may not have prostate cancer.
Likewise, some men with normal PSA values actually harbor
prostate cancer. Approximately 25
percent of men who are diagnosed with prostate cancer have PSA
levels in the normal range. In these cases, prostate
cancer is detected by digital rectal examination of the
prostate, by removal of a portion of the prostate during surgery
for prostate enlargement, by monitoring of PSA velocity or by
other methods.
An even more established method of PSA
utilization is for the follow-up in patients after treatment for
prostate cancer. PSA levels guide clinical decision-making
after every form of treatment. In general, PSA levels
accurately reflect the status of the cancer. Additional
methods of cancer monitoring include bone and Prostascint
scanning for metastatic disease.
When there is a suspicion of prostate cancer,
men generally undergo transrectal ultrasound guided needle
biopsies of the prostate. This is a procedure performed in
the urologist's office. Because procedure is anxiety
provoking and uncomfortable, sedation and pain medications are
usually used. With adequate premedication and
communication on the part of the urologist performing the
examination, most patients have no complaints concerning the
procedure. Ultrasonography allows visualization of the prostate such that
biopsies may be directed into specific areas of the prostate
which most commonly harbor the cancer and areas of the prostate
which demonstrate visible abnormalities on the ultrasound image.
At the Urology
Center, our physicians personally perform both the
ultrasound examination and the biopsies. There is no
substitute for personal involvement [by the urologist] with this extremely
important process.
A great deal of experience in ultrasound imaging
of the prostate is necessary to positively diagnose or exclude
the presence of prostate cancer. At some urology clinics,
the ultrasound examination is relegated to a technician.
In those circumstances, the urologist may come into the
ultrasound room briefly, only to oversee the
the short portion of the procedure when the actual biopsies are
performed. In these circumstances, when the
urologist has not performed the ultrasound examination, error
may be introduced into the process. That is, prostate
cancer may be missed. At the Urology Center, our
physicians personally perform both the ultrasound
examination and the biopsies. No technician is involved. We have performed prostate
biopsies on thousands of patients. There is no substitute
for personal involvement with this extremely important process.
The prognosis and treatment options for prostate
cancer depend on the stage and grade of the cancer.
Therefore, once prostate cancer is diagnosed, the tumor
must be staged. Prostate cancer staging may involve bone
scanning, CT scanning, additional blood testing, and lymph node
dissection. Prostate cancer commonly first spreads to
large glands near the prostate called the seminal vesicles.
The seminal vesicles may be biopsied using transrectal
ultrasonography. Prostate cancer also commonly spreads to
lymph nodes within the pelvis. CT scanning can detect
enlargement of these lymph nodes after which CT guided needle
biopsies may prove the presence of cancer within the lymph nodes.
Physicians at
the Urology Center are experienced with laparoscopic pelvic
lymph node surgery and the appropriate indications to use
this specialized diagnostic tool.
However, the lymph nodes may contain cancer even
if the lymph nodes are not enlarged on a CT scan. In such cases, lymph
node biopsy may be necessary, either by means of open surgical
removal of the lymph nodes or by laparoscopic lymph node
dissection. The need for these tests must be determined
after careful analysis by and urologist who has
knowledge of current prostate cancer evaluation and management
methods, as well as experience with these methods.
Laparoscopic pelvic lymph node resection is commonly performed
in limited circumstances when there is significant
suspicion for cancer involvement of the pelvic lymph nodes.
Laparoscopy involves placement of thin instruments through the
abdominal wall in order to perform operative procedures without
the need for large skin incisions. Laparoscopic pelvic
lymph node resection allows for the accurate determination of
the presence or absence of prostate cancer within the pelvic
lymph nodes, without the morbidity associated with a large
surgical skin incision. Physicians at the Urology Center
are experienced with laparoscopic pelvic lymph node surgery
and the appropriate indications to use this specialized
diagnostic tool.
Once prostate cancer has been accurately
diagnosed and staged, treatment may begin. The choice of
treatment greatly depends upon the stage and grade of the cancer and
personal choices of the patient. When prostate cancer has
escaped the prostate gland and spread beyond the prostate, it is
presently considered incurable. However, multiple treatment options
exist that may delay the progression of the cancer for many
years in many such cases. In these cases treatment options
include simple observation without treatment, hormonal ablation
and chemotherapy. Chemotherapy for prostate cancer is an
old idea but until recently, chemotherapy has not proven
beneficial. Chemotherapy is now generally reserved for
advanced cases of prostate cancer which no longer respond to
other treatments. On the other hand, hormonal therapy is the
standard of care for advanced prostate cancer. The risks
and potential benefits of each of these forms of treatment must
be carefully weighed.
The primary
issue ... is whether or not hormonal therapy should be started
immediately or ... postponed until later in the course of the
disease.
In most prostate cancers, the vitality of the
majority of cancer cells is dependent on stimulation by male
hormones (androgens) which are produced in the testicles
(testosterone) and, to a lesser degree, in the adrenal glands. The primary issue to be
considered in cases where patients have decided against
undergoing potentially curative cancer treatment, is whether or
not hormonal therapy should be started immediately or whether
hormonal therapy should be postponed until later in the course
of the disease.
At first glance, even the question of delaying
treatment might seem irrational. However, hormonal therapy
may have significant side effects and the benefits of early
treatment versus later treatment has not been established with
absolute certainty. Just within the last several years,
information has come to the forefront indicating that early
hormonal therapy may delay the progression of prostate cancer
and may increase survival time. Again, the question is
whether or not the side effects of hormonal therapy are worth
the potential benefit of increased survival time. Side
effects of hormonal therapy may include impotence, decreased
libido, gastrointestinal upset, breast swelling and tenderness,
hot flashes, hair loss, deterioration of muscle mass and
osteoporosis. Thus, patients with prostate cancer not
confined to the prostate must individually decide whether or not
they will undergo hormonal therapy early or later in the course
of the disease.
Patients with prostate cancer not confined to
the prostate must also decided which type of hormonal therapy
they will use. Three broad hormonal therapy options are
surgical hormonal therapy vs. medical hormonal therapy vs.
combined surgical and medical hormonal therapy.
Testosterone is a male hormone produced primarily by the
testicles. A much smaller amount of male hormone is
produced in the adrenal glands. Surgical removal of the
testicles, (orchiectomy), significantly reduces the available
testosterone. Likewise, use of luteinizing hormone
releasing hormone (LHRH) agonist medications such as leuprolide
(Lupron and Viadur) and goserelin (Zoladex) reduce testosterone to levels
as low as levels produced by surgical orchiectomy.
Therefore, the standard choices, surgical orchiectomy,
leuprolide and goserelin are thought to be nearly equivalent with regard to
their effects on testosterone, their effects on prostate cancer
and their side effects. However, leuprolide and goserelin are
reversible treatments, whereas surgical orchiectomy is not
reversible obviously.
Another question to be answered in patients
considering hormonal therapy for prostate cancer not confined to
the prostate gland concerns whether or not to use medications
called antiandrogens, that block the effects of androgens produced in
the adrenal glands. Without the use of the antiandrogen medications in
addition to goserelin, leuprolide or orchiectomy, the adrenal
glands continue to produce male hormone. Even this small
amount of androgen may allow growth stimulation of prostate
cancer cells. There are several categories of medications
which may block the effects of adrenal androgen hormones and
testicular hormone (testosterone). In the United States, the
primary antiandrogen medications used for this purpose are flutamide (Eulexin)
and bicalutamide (Casodex). Neither of these medications
decrease male hormone levels. Instead, they prevent male
hormone from entering prostate cancer (and other) cells, thus preventing
androgen stimulation of prostate cancer.
... there has
been a great deal of disagreement among physicians and
scientists as to whether the addition of antiandrogens provides
significant benefits ...
In the past there has been a great deal of
disagreement among physicians and scientists as to whether the
addition of antiandrogens provides significant benefits to
prostate cancer patients. Some studies have shown a
benefit in increased survival of patients using these
medications along with standard hormonal treatments (like
orchiectomy or leuprolide/goserelin). Other studies have
shown little if any benefit; however, until recently most
studies have only looked at patients with more advanced cancer.
A recent very large clinical trial of prostate cancer patients
showed that the addition of bicalutamide to standard hormonal
treatments reduced the risk of cancer progression (spread) by 42
percent. Whether or not this will result in a survival
benefit (fewer deaths from prostate cancer) is presently
unknown.
Another question concerns whether or not
antiandrogens like flutamide or bicalutamide should be used
alone, without the standard hormonal treatments like surgical orchiectomy,
leuprolide and goserelin. Of course the main reason that
this question has been raised is the fact that antiandrogen
medications have less deleterious effects with regard to sexual
dysfunction (loss of libido and erectile dysfunction). Recently, a
relatively small study of patients of about 500
prostate cancer patients showed promising results with the use of bicalutamide alone.
The study showed that bicalutamide 150 mg/day alone
was as good as surgical orchiectomy alone in patients with
locally advanced prostate cancer, in terms of mortality and
progression of disease.
In the recent clinical study and other studies
mild breast
enlargement and pain were common side effects of bicalutamide.
Hot
flashes are common with leuprolide, goserelin surgical orchiectomy.
However, overall, the group of patients using bicalutamide alone
seemed to have a better quality of life, including better sexual
function, as compared to the group of patients having undergone orchiectomy.
Low dose radiation treatment to the breast tissue is
unquestionably helpful in preventing painful breast swelling in
patients using bicalutamide and flutamide. However, the
radiation must be given before treatment is started.
... most any
form of hormonal therapy may cause osteoporosis.
It appears that most any form of hormonal
therapy may cause osteoporosis. Until recently this
problem was not well recognized or at least not well-publicized.
Now that many patients are using hormonal therapy early on in
the course of prostate cancer disease, many doctors have become
concerned about the longtime negative effects of hormonal
therapy, including the long term effects on bone. Several new medications have been
developed to combat this problem. Men on long-term
hormonal therapy may be monitored for osteoporosis using bone
densitometry tests.
For men with clinically localized prostate
cancer and a life expectancy of at least ten years potentially
curative treatment options should be considered. Three
broad categories of potentially curative treatment include surgery, radiation
therapy and cryotherapy. Cryotherapy ablation of the
prostate implies freezing of the prostate gland.
Cryotherapy has been used for many years for the treatment of
prostate cancer but recent advances in the technique make
cryotherapy an option for some patients. Presently, many
urologists feel that cryotherapy may be considered for patients
who would otherwise undergo radiation therapy.
At one time ...
[radiation therapy] was the most popular form of treatment.
Radiation therapy has been used for many years
for the treatment of prostate cancer. At one time it was
the most popular form of treatment. The basic
types of radiation therapy are external beam radiation therapy, brachytherapy
("seeds") and combined external beam and brachytherapy.
External beam radiation therapy involves radiation delivered
from outside the body. This treatment has been used for
many years but, as for every other treatment for prostate
cancer, refinements of technique have decreased its complications.
Like external beam radiation, brachytherapy has also been
used for many years. The technique involves placement of
radioactive "seeds" into the prostate gland. Just as for
most other treatments for prostate cancer, refinements of
technique have improved its results and decreased its
complications.
Potential complications of radiation therapy
include urinary incontinence, rectal irritation, bladder
irritation, urinating difficulties, gastrointestinal side
effects, urethral scarring, impotence, bloody urine and others.
However, the most disturbing complication of radiation therapy
(or any therapy for that matter) treatment failure with
persistent or progressive prostate cancer, even after treatment.
While some studies reveal excellent early results
of radiation therapy treatment, others show treatment failure
and persistent or progressive prostate cancer in up to 50-75
percent of cases. As with every other treatment, the
results largely depend on the grade and stage of the cancer at
the time treatment is initiated. Once again, prostate
cancer screening is important.
Surgical treatment of prostate cancer entails
removal of the entire prostate gland and the glands near the
prostate the seminal vesicles. The prostate may be
approached in several ways: through the lower abdominal wall
(radical retropubic prostatectomy), through the perineum between
the scrotum and anal opening (radical perineal prostatectomy) or
by placement of thin telescopic instruments through the
abdominal wall (laparoscopic radical prostatectomy). Each
variation offers potential advantages for certain patients.
Likewise, each surgical variation has disadvantages and
potential complications. For example, while some surgeons
feel that perineal prostatectomy allows a speedy recovery, some
urologists feel that they can not effectively remove all of the
cancer in or around the prostate using this approach.
Furthermore, it is not possible to assess the pelvic lymph nodes
and remove them when performing a perineal prostatectomy.
Laparoscopic prostatectomy has the potential advantage of a
quick
recovery and this approach also allow for assessment of the pelvic lymph nodes. However, laparoscopic prostatectomy has
its own potential problems, not the least of which is increased
length of time of the operation, thereby exposing the patient to
additional anesthesia. Furthermore, some laparoscopic
surgical cases are unsuccessful, at which time the patient must
additionally undergo the standard open surgical incision.
Furthermore there are no long term reports concerning success
rates of this type of surgery. Surgeons at the Urology
Center do perform laparoscopy but we feel that laparoscopic
radical prostatectomy cannot be considered the surgical standard
of care at the present time.
The surgeons at
the Urology Center ... have performed hundreds of these [radical
prostatectomy] procedures with excellent results.
The surgeons at the Urology Center generally
perform prostate cancer surgery by means of the radical
retropubic prostatectomy. We have performed hundreds of
these procedures with excellent results. With the
patient completely asleep, a short skin opening is made just
above the pubic bone, allowing the operating surgeons to
evaluate all of the structures which may contain cancer and require removal,
including the pelvic lymph nodes, the prostate and the seminal
vesicles. Lymph node removal decisions are made based upon
PSA levels, the pathological grade of the prostate cancer, the
volume of the cancer the direct assessment of the pelvic lymph
nodes at the time of surgery. Commonly, pelvic lymph node
removal is not required thereby decreasing the surgical
complication rate. Specifically, the potential
complication of the development of a collection of lymph fluid
within the pelvis (lymphocele formation) may be largely avoided.
Many urologists feel that the radical retropubic
approach offers the best visualization of the prostate and
seminal vesicles, potentially allowing more efficient removal of
all the cancer. For many reasons, the radical retropubic
prostatectomy is the procedure of choice for the majority of
urologic surgeons. Of course, the choice of the operative
approach depends upon the personal experience of the operating
surgeons and the Urology Center surgeons have a large experience
with radical retropubic prostatectomy. No matter the surgical approach, when prostate
cancers are detected in men who have followed the guidelines for
prostate cancer screening, radical prostatectomy results in cure
of the prostate cancer in the majority of cases.
... patients
undergoing radical retropubic prostatectomy may expect a two
night hospital stay with only minor postoperative discomfort.
Our patients undergoing radical retropubic
prostatectomy may expect a two night hospital stay with only
minor postoperative discomfort. Approximately 90 percent
of patients go home from the hospital on the second
postoperative day. Occasionally, patients may choose to go
home only after one night in the hospital and occasionally an
older patient may stay longer. The secret to speedy
recovery after surgery of this type is thorough preoperative
education (concerning what to expect during the brief
hospitalization) and excellent pain control with an early return
to physical activity. In fact, most patients are up and
out of bed or walking just several hour after surgery!
One of two contemporary methods of postoperative pain
relief are used. Most commonly patients use a patient
controlled analgesia (PCA) device which allows the delivery of
pain medication with the press of a button. This is
totally controlled by the patient. Alternatively, some
patients choose an epidural anesthetic which entails placement
of a small catheter around the nerves in the lower part of the
back. The catheter is placed at the time of surgery but
postoperatively pain medication is continuously delivered to the
lower part of the back. This generally results in the
total absence of pain after the surgery. Of course,
eventually the PCA or epidural must be discontinued. Most
patients thereafter experience some relatively mild soreness
which is easily controlled using a non-narcotic oral medication,
sometimes supplemented with a mild oral narcotic type
medication. In either case, patients are generally eating
and walking the halls of the hospital no later than the morning
of the day following surgery.
Without a doubt the most common grievance
patients have with prostate surgery relates to wearing of a
the catheter in the bladder. Catheter discomfort can be
managed with special medications and irritation improves with
time. While some men
experience painful bladder spasms, other patients have no
complaints with regard to the catheter. Unfortunately, no
matter which surgical technique is used, wearing a catheter
after the surgery is absolutely mandatory. However, using
the radical retropubic technique, patients generally only have
to use the catheter about ten days. However we have known
other physicians to keep the catheter in place routinely for
three-six weeks. Obviously, patients go
home with the catheter and later have it removed in the doctors
office or by a home health care nurse.
Absolutely
every form of prostate cancer treatment has been linked to the
development of erectile dysfunction (ED).
All prostate cancer treatments have side
effects. There is no known prostate cancer treatment which
does not cause sexual dysfunction. Absolutely every form
of prostate cancer treatment has been linked to the development
of erectile dysfunction (ED). Patients may expect erectile
dysfunction in up to 50 percent of the cases after radiation
therapy and in up to 100 percent the cases after cryotherapy,
standard hormonal therapy and prostate cancer surgery.
In our
experience approximately 50 percent of patients undergoing the
nerve sparing procedure may continue to have normal erections
after surgery.
Any type of prostate cancer surgery can cause
erectile dysfunction. However, in selected cases, sexual
function may be preserved by a surgeon experienced in the
procedure known as nerve sparing radical prostatectomy.
Using this procedure, tiny nerves which run directly around the
prostate and seminal vesicles may be preserved during surgery,
allowing patients to continue to have penile erections
postoperatively. In our experience approximately 50
percent of patients undergoing the nerve sparing procedure may
continue to have normal erections after surgery.
Otherwise, patients commonly require Viagra or other methods of
erectile dysfunction treatment after surgery. Furthermore,
of patients who do develop ED after surgery, a greater
percentage of those patients having undergone a nerve sparing
radical prostatectomy may respond to Viagra, as opposed to those
having a standard non-nerve sparing surgery.
... be wary of
surgeons who claim that they "always" perform nerve-sparing
radical prostate cancer surgery ...
Patients should be wary of surgeons who claim
that they "always" perform nerve-sparing radical prostate cancer
surgery or that they will decide whether or not to perform a
nerve sparing procedure only during an operation. A
nerve-sparing procedure cannot and should not be performed in a
very considerable number of men with prostate cancer.
Reasons include high grade cancer, locally advance stage of
cancer, patients with ED or marginal erectile function,
unwillingness on the part of the patient to accept a low risk of
incomplete removal of all of the cancer and, last but not least,
the location of the cancer within the prostate. Some
urologists haphazardly label the small pieces of tissue removed
form the prostate during the prostate biopsy session such that
no one can tell the exact spot that the cancer is located within
the gland. This may limit that urologist's ability to
guide patients with regard to making decisions concerning
whether or not to recommend a nerve-sparing surgery.
Also, be cautious of surgeons who tell their
patients the a decision concerning a nerve sparing procedure
will be made based solely on findings during surgery.
Generally, the decision can be made well before the operation,
although in uncommon cases the decision to perform a
nerve-sparing procedure may be changed due to adverse findings
at the time of the operation. In summary, be cautious of
any surgeon who claims that he or she performs nerve sparing
radical prostatectomy procedures, yet fails to completely
map-out the entire prostate when performing prostate biopsies.
If mapping of the prostate is properly done, the results are
recorded on the report from the pathologist who interpreted the
biopsy results.
Many patients who decide not to undergo a
nerve-sparing procedure ultimately opt to undergo placement of a
four-piece inflatable penile prosthesis. In fact, the
reservoir portion of a penile prosthesis can be safely placed at
the time of the radical retropubic prostatectomy, without making
any additional skin incision. This may not be the case
with other forms of prostate cancer surgery. Of course
there are many other methods of ED treatment, but beyond Viagra,
there are none with satisfaction rates as high as a four-piece
inflatable penile prosthesis. (Please visit our
Male Urology and Erectile Dysfunction Center of Excellence
for additional information.)
Additionally, prostate cancer surgery, radiation
and cryotherapy may also result in urinary incontinence,
accidental leakage of urine. Of these treatments, prostate
cancer surgery more commonly results and urinary incontinence.
Some studies have reported incontinence in the majority of men
undergoing prostate cancer surgery. However, most reports
indicate that less than two percent have incontinence severe
enough to undergo corrective surgery. The younger the
patient the less the chance of incontinence. Incontinence
may be treated with medication, exercises, behavioral
techniques, biofeedback training and surgery. Surgical
treatments are reserved for severe cases. This treatment
may entail cystoscopy with injection of a bulking agents such as
collagen within the walls of the urethra. Pubourethral
sling surgery is an effective alternative. However, the
most effective way to manage postoperative stress urinary
incontinence in men having undergone prostate cancer surgery is
placement of an artificial urinary sphincter (AUS).
... the most
effective way to manage postoperative stress urinary
incontinence ... [is] an artificial urinary sphincter (AUS).
The artificial urinary sphincter involves
placement of a tiny donut-like fluid filled cuff device around
the urethra. The cuff is connected to a tiny pump located
within the scrotum. By squeezing the pump several times,
fluid is transferred from the cuff to a fluid reservoir
deflating the cuff, thereby allowing the urine to pass through
the urethra. Normal voiding of urine results. Fluid
then automatically refills the cuff, occluding the urethra,
preventing unwanted urine leakage. The results of the
artificial urinary sphincter procedure are excellent, with most
patients reporting complete dryness or drastic improvement.
In summary, rapid progress is being made with
regard to the diagnosis and treatment prostate cancer.
Additionally, studies are ongoing investigating methods of
prostate cancer prevention. Worldwide, more men than ever
are undergoing prostate cancer screening. Prostate cancer
screening is resulting in earlier detection of prostate cancer
at the stage when the cancer may be treated for cure. In
fact, there are clear indications that the mortality rate from
prostate cancer is decreasing. Early indications strongly
suggest that this progress is the result of a combination of
prostate cancer screening with early detection and treatment.
Furthermore, the complications of prostate cancer treatment are
clearly decreasing with refinements of medication, radiation
therapy, cryotherapy and surgical techniques. While every
form of prostate cancer treatment has been associated with the
development of erectile dysfunction, this problem is readily
treatable such that no man should have to live with this
problem. The physicians at the Urology Center not only
have extensive experience with the evaluation and treatment
prostate cancer, but they also have experience with the
