For
those interested in HIFU as practised in Canada,
this link give some useful information.
There
are basically two approaches to HIFU - that denoted as Sonablate 500 and that
denoted Ablatherm. Both are claimed to be better than the other and so it might
be in your interests to read Transrectal
HIFU: The Next Generation? a solid paper published by PCRI Insights in 2004.

This
therapy has many acronyms and names. Some are ADT, ADT2, ADT3, CHB, CHB2, CHB3,
CHT, HBT. Technically all refer to the main object - to control the body's production
or absorption of testosterone or, more precisely, dihydrotestosterone, commonly
referred to as DHT. Hormone therapy is sometimes described as a chemical orchidectomy
- the advantage is that it is reversible. Usually a combination of drugs is used
to prevent production of testosterone by the testicles and block the cancer tumour
from using the testosterone produced by the adrenals. This can reduce the size
of the tumour in about 80% of cases.
Historically,
hormone therapy was used primarily as a treatment of metastasised cancers or as
a salvage procedure for a failed treatment. However, it is now often used as a
primary treatment to reduce the size of the prostate prior to other treatment
- referred to as neo-adjuvant therapy - and sometimes after primary treatment,
such as radiation therapy, when it is referred to as adjuvant therapy. Some surgeons
will not operate on a prostate where this therapy has been used prior to surgery
as the treatment alters the cellular structure of the gland itself. As is the
case with most issues to do with prostate cancer, there is considerable disagreement
about when and how this therapy should be applied.
The
drugs used often have different names in different countries, but the most common
ones are: Lupron
(leuprolide acetate) and Trelstar
(triptorelin pamoate) which are both
injected intramuscularly into the buttock. Zoladex (goserelin acetate) is injected
subcutaneously into the lower abdomen.
Reported
side effects of hormone therapy are numerous but are usually, but not always,
reversible if the treatment is stopped - these side effects are sometimes referred
to as Androgen
Deprivation Syndrome, which results from lack of testosterone. One of the
most serious - and some say, inevitable - results of hormone
therapy is loss of bone mineral density
or osteoporosis, which can result in fractures and/or collapse of spinal vertebrae.
It can be treated/prevented IF the medic or his patient is aware of the
risk. Regrettably far too many people in the medical world seem to be ignorant
of the side effects of the drugs they prescribe, so the burden of tracking and
education devolves upon the patient.
The
principle side effects of of major concern to men are loss of libido and erectile
function - this therapy is often
referred to as "chemical castration" and men can and are labelled as
eunuchs. Although
little can be done about the effects of loss of libido and erectile function,
this piece -
Castrated, Emasculated, But Hardly Disempowered!
might be useful for men concerned about emotional aspects of these issues.
One
of the other annoying side effects - hot flushes - can be treated successfully,
although this seems not to be well-known among some inattentive medics. Three
options are:
1.
Depo
Provera (medroxyprogesterone, a synthetic form of the female hormone progesterone),
the "label" use of which is as a female contraceptive. In the 400 mg (contraceptive)
dosage, a study (Langstroer et al.J Urol. 2005 Aug;174(2):642-5,
Pub Med ID 16006929) has demonstrated excellent results in relief
of hot flushes among men on ADT (androgen deprivation therapy).
2.
Paxil (paroxetine hydrochloride), an antidepressant. A side effect is to relieve
hot flushes.
3.
Effexor (venlafaxine hydrochloride), an antidepressant. Same story.
4.
Megace
(megestrol acetate): has
been used successfully to relieve hot flushes, although some
concern has been expressed by one doctor that it might encourage PCa development
where the tumor has mutated. Unfortunately, there appears to be no way to be certain
whether this has occurred.

Therapy"

This
procedure was pioneered in France but is now done in the United States and many
other countries. The surgery is carried out through three small incisions and
is done by a surgeon with the assistance of small robots.
The
main advantage claimed for this procedure is that recovery is quicker because
there are no large incisions to reach the prostate - just the relatively small
ones needed to get the equipment to the site. Of course there are still the side
effects of the surgery because the actual operation doesn't change - the nerves
needed for erection can still get damaged, the urethra still has to be cut and
re-attached to the bladder and so on. Some surgeons say they do not like the procedure
because they cannot feel the texture of the gland and that they need this to identify
more clearly where the tumour might be located (this is an important issue in
making decisions on nerve sparing). The surgeons who favour the procedure say
that they can see what they are doing much more clearly and are therefore better
able to make better incisions and joins.
Surgeons
who are skilled in the procedure produce good results, but there is a steep learning
curve.

Men
diagnosed with late stage prostate cancer may go into remission if their testicles
are removed. This is known as an orchidectomy or orchiectomy and is an effective
method of lowering the testosterone level. It is important to reduce the level
of testosterone as this is a major source of 'fuel' for the growing cancer. There
are few side effects, but there are many psychological reasons which deter men
from considering such an approach. A similar effect can be produced through the
use of Hormone Therapy , which is reversible, an orchidectomy
is not.

This
was regarded as an excellent alternative treatment and there were many reports
of excellent results, including from one of our members. Concerns were raised
however that the compound might rely on estrogen compounds and that these might
give rise to thrombosis. The compound did not have FDA approval and was heavily
criticised in The New England Journal of Medicine -- September 17, 1998 issue.
It was withdrawn from the market following action by the government of California
and was the subject of considerable litigation. There are other clones said to
be as effective as PC-Spes, although none appear to be so, based on anecdotal
evidence.
One
of the clones is a compound marketed as Prostasol.
There are said to be two versions of this - Dr Donsbach's which is marketed mainly
in the USA and another marketed in Europe.
There have been reports of men suffering from thrombosis - see Venous
Thromboembolism as an example - and great care should be taken in using these
compounds, which should only be taken under medical supervision. it may be neccessary
to use warfarin/coumadin to reduce the potential for blood clotting.

PHOTO
DYNAMIC THERAPY (PDT) |
Photodynamic
therapy (PDT) has been used to treat cancer for
more than 25 years. Although the focus has been primarily on surface or superficial
lesions, such as skin cancer, there has been a movement to find ways of treating
of deeper malignancies, such as prostate cancer. The way in which this therapy
works is that a photosensitizing drug is introduced. When this is irradiated by
light at a specific wavelength it generates an cell death, primarily through apoptosis,
micro vascular damage, and an anti-tumor immune response. In treating prostate
cancer infra-red light is used introduced to the gland by probes inserted through
the perineum in much the same way as Brachytherapy probes are dealt with. The
procedure has not been approved by the FDA for the treatment of prostate cancer,
but there is a growing body of evidence concerning its efficacy and the innate
minimally invasive characteristics of PDT suggest that it should become an important
addition to the growing array of techniques in interventional oncology.

This
form of radiation therapy has not been as widely used for prostate cancer as some
of the other forms of therapy. It uses atomic particles which deposit most of
their energy at the end of their travel. It is claimed that they can be delivered
more selectively, that damage to surrounding healthy tissue is reduced and that
there are likely to be fewer side effects than EBR. Long
term data is becoming available, and the procedure, which was very expensive,
has come down in price.
The
Treatment Centre at Loma Linda Proton Treatment
Centre was the first of its kind in the U.S. although there are now three
proton centres in the USA currently treat cancer patients, including Massachusetts
General Hospital and Midwest Proton Institute.
There are also centres in other
countries, although some may not treat prostate cancer. The position in the
USA will change in May of 2006, when one of the leading cancer centers in the
world, the M.D.
Anderson Cancer Center, plans to begin treating patients with proton clinical
trials. The Florida Proton Therapy Institute, Jacksonville, will be ready in the
summer of 2006. Future proton centers include Hampton
University’s proton facility to be completed by late 2008 and the University
of Pennsylvania’s plans for a proton therapy facility in Philadelphia.other facilities
in the US which offer this treatment.

This
is the operation most widely used - certainly in the U.S. and which is often referred
to as the 'gold standard'. It is a complex operation and there is considerable
controversy as to the efficacy of the operation, its cure rate and the serious
side effects which accompany it. There are two main forms of radical surgery used
- the retropubic approach, where an incision is made in the lower abdomen - and
the perineal approach, where the incision is made between the rectum and the scrotum.
For more detail on the retropubic approach, see Radical
Surgery .
You
will come across reference to the nerve sparing procedure, used with the retropubic
approach which is said to have a better result as far as side effects are concerned.
Not all surgeons are trained for this procedure and it cannot be used in all cases.
There was considerable controversy in 1994 regarding what was then the 'new' technique.
Subsequent studies have demonstrated that there is no discernible difference in
outcome between the two approaches - they key factor is still the skill of the
surgeon.
