1985-2004
A ‘summary’ of a long but revealing period of time!
In 1985/86 I spent hundreds of hours in my car researching a French Autoroute Guide. I remember having the urge to void my bladder too often every day. My Amersham doctor explained that this was a symptom of the ‘prostate gland’. (I left him convinced he had said ‘prostrate’ gland; like most men that was all I knew about the thing!)
In 1989 I had the first of several urine ‘retentions’ (the inability to pass any urine at all; the answer was to have a catheter inserted). Always after a drug had been used, except once when I had drunk over half-a-bottle of Chianti red wine! The first drug was an anti-cholinergic medication, used as a pre-med for my detached retinas eye surgery. I found that out for myself months and months later. Another was an anti-histamine, promethazine hydrochloride, used in ‘Night Nurse’. The non-drug was excessive natural tyramine found in Chianti (in drug form tyramine is used in anti-depressive medications). I found out all the above myself! Whatever the causes my prostate gland closed tight too easily, stopping the bladder voiding. I made sure I knew all the foods/medicines that could cause problems – and to avoid them.
In 1993/94 I again spent hundreds of hours sitting in my car researching Mapaholics’ France. This time, without initially realising it – cutting down on fluid input to avoid constant voiding of urine – I must have had a series of infections in my bladder and prostate gland.
After an especially nasty infection in 1995 I was referred to an urologist at Warwick Hospital. I had, for my first ever PSA reading, a very high score of 29. However after a DRE (up the rectum!) the consultant concluded he had found no sign of cancer (in the ‘focus’ sample he had removed from the gland); and he made no mention of an enlarged prostate size.
Now, looking back, I conclude that my prostate gland ‘troubles’ probably first went nasty on me during 1985/86 and 1993/94: I reckon that was when the cancer started.
From 1995 to 1999 I saw the urologist every six months.. Some raised PSA scores were high, but always below the first 29; ‘prostatisis’ was the diagnosis each time. However, after passing a spot of blood in my urine in September 1999, I was given a cystoscopy; access to my bladder and prostate via the penis. Seven ‘samples’ were taken from the prostate, with just one showing signs of cancer; and a Gleason rating (the cancer’s aggressiveness) of 6 (not too aggressive). Now my prostate was reckoned to be about 140gms – the normal size for a man of my age was 40gms (early 60s).
I had already started delving into research material: on prostate cancer, treatments and diet. Zoladex was the initial drug prescribed – but after 13 months my gland had not reduced one iota in size. Normally the gland reduces by least half in 13 weeks.
So, alas, the reality of my health outlook was that I had a massive gland (which continued to grow!) – the size of the thing effectively prevented me from having all the radical treatments available to me: prostatectomy (removal of the gland), radiotherapy (even conformal – that was a blow), freezing, radioactive pellets; and, later, the remarkable HIFUS (high intensity focused ultrasound). Yes, I could have gone ahead – but with the 100% certainty of chronic morbidity, seriously prejudicing my quality of life.
I was stuck with Zoladex (and being a eunuch), replaced by Casodex after 15 months (less spiteful side-effects but still almost 100% castrated!). I started to see, in turn, an oncologist and urologist every three months. From 2000 to 2004 my PSA readings stayed low, from about 3 to 9 (the size of the prostate ensures higher readings compared with a normal-sized gland).
In 2002 I had my second-ever ultrasound; this showed a breach in the hardish capsule which surrounds the gland – but the medics decided that presented no problems. Note: prostate cancer does not kill if it is contained within the gland!
Now, with me looking back, and you about to read what followed in 2005 onwards, I conclude I was let down badly. As a matter of course patients should have six-monthly ultrasounds; and, in cases similar to mine, a cystoscopy every six months. To check what’s going on in the prostate gland.
Question: is it not amazing within a few weeks of the end of 2004 I was to discover that my prostate size was in excess of 160gms; that my gland was massively vascular; and that, right out of the blue (with PSA always under 10 since 1999), my Gleason score was a top pf the scale 9 (as aggressive as hell). Worst of all, the TURP operation to come was to release myriad nasty cancer cells into my body. Now read on.
Early January 2005
Since I put the 'December 2004' (early in the month) notes up on the
website there has been a worrying deterioration in my voiding. Daily
voidings have risen to double figures; actual output, per voiding, has
plummeted - usually not much more than 100ml; 220ml is an exception.
Worse still, on more than a handful of nights, I couldn't pass any urine
and I found myself sitting in three inches of hot bath water - relaxing
the prostate - or, several times, taking an emergency Doralese tablet
(at 20mg this acts like a tap full-on; better to 'try' to slice the
thing into thirds; say 7mg each). I hadn't had to do this to pass water
since 1998, my last Chianti-driven total retention saga - a catheter
job in the end.
In a further letter to my urologist I made a telling, controversial
point - of interest to every GP. Read the 7th para in the 'Dec 2004'
notes. If the last sentence is right then my prostate is growing significantly
because, not only is there a 'lower amount of testosterone available'
(remember only about 10% of the 'circulating' variety can be absorbed),
but Casodex blocks off the stuff completely. So the gland works
harder and harder for nowt. I'm sure you see what my conclusion is:
no wonder then that my prostate must be even larger then the last ultrasound
count at 140gm.
Two days ago I asked my GP to prescribe Cardura (which my younger brother
Keith uses with some success). Instead he prescribed Doxazosin.
Doralese, plus the latter two, are all derived from 'prazosin hydrochloride'
- an alpha-blocker to reduce blood pressure. (The notes with the pills
say nothing at all about BPH!)
I've elected to have 4mg capsules. To start with I cut a tablet into
two: and took 2mg a time. I've taken one as I go to bed (to avoid the
mid-nightly worries expressed earlier; and the other 2mg at about 6.00
a.m. - the start of the usual four-hour whoosh of passing water (a pattern
with me for some years). No point in taking any more of the drug between
lunch and evening meal time as my norm has always been to pass water
at lunchtime, evening meal time and before going to bed.
So far the results have been very pleasing. Two 200ml voidings during
the night; and 3 to 4 from getting-up to lunchtime. You certainly realise
it is a blood pressure drug. My blood pressure is/has been bog standard
for yonks. My two-steps-at-a-time run up two floors to my flat will
have to be watched: slight dizziness! Shame: that, several times a day,
helps me to keep very fit. Maybe it will go. Likewise: you feel almost
a laid-back 'malaise' after taking 2mg; maybe that will go in time.
I must get my prostate size reduced - always my bête noire. So,
I'm putting pressure on my oncologists to do the following:
a) another ultrasound to determine my prostate size;
b) a blood test for oestrogen and testosterone levels;
c) to consider prescribing, as a guinea pig male, Anastrozole (a friend
of mine, of the same age, had a recent mastectomy; then Tamoxifen which
proved too onerous; and is about to use the newish drug).'New' here,
in use five years ago at the Mayo Clinic (their detailed notes are an
eye-opener; see what follows).
Many cancer tumours (BPH too) grow in response to oestrogen. Anastrozole
does better than just blocking oestrogen; it has an effect earlier in
the chain of events by stopping the production of oestrogen (a BHP bonus
too). The amount of oestrogen that the tumour is exposed to is reduced,
limiting the growth of the tumour (for prostate cancer too). Can you
fault my logic? If so please tell me.
February
and March 2005
The final two sentences above: no need to tell me; I solved the 'logic'
myself! The answer was found in the Mayo Clinic notes: among the many
side-effects are 'urinary difficulties' and 'increase in blood pressure'.
Both an absolute no-no for prostates. Tamoxifen, in reality, is much
too toxic and unpredictable for prostate cancer treatment.
Anyway,
all the events listed above in early January, came to a grinding halt
on the 18th of that month: 'retention with overflow' forcing catheterisation.
Read the chapter 'Prostate Problems' (click-on in the drop-down menu
under the 'Author' button).
What now
follows are the contents of three emails:
Email
1 to Dr. Desmond Tivy (11 Feb)
Tuesday 1 Feb proved to be a bad day: the planned removal of the catheter.
Plan A was to see if I'd manage on my own (I had taken Flomax for four
days to prepare for that possibility). But no way: back to the hospital
in under an hour, and after drinking plenty of water, to be re-catheterised.
Back home once more, did some work, again drank plenty of water - but,
no, no urine getting through even with the catheter! Back to the hospital
in a real state; nowt quite like a vary full bladder unable to empty.
I was then 'Dyna-rodded'. My word. What relief: water, plus gas, equals
aerated water - which pushed everything in the bladder out. Litres of
it into a vast beaker. The most stunning sight was the bottom two inches
- like a blackcurrant 'soup': literally hundreds of small pieces of
dark clotted blood - all caused by a catheter in just two weeks! (I
had seen a few during the original catheterisation.) No wonder I couldn't
pass anything with or without a catheter. I had been utterly clogged-up.
This is called Prostate trauma.
Since 1 Feb I have only seen two bags of light rosé urine ('bag'
attached to my lower right leg); otherwise all light yellow.
I'm drinking gallons of water. Plan B is now in motion. I'm paying to
have a TURP on 3 March - to ensure the surgeon has plenty of
time to be careful and skilful and to able to cauterise blood vessels.
What is now certain is that I have an awfully 'vascular' prostate. BAD
NEWS.
The ultrasound I paid for at the end of Jan showed my prostate size
at 160+gm. I've got to do something drastic as the prostate is pushing
up into the bladder, the latter looking more like a Lac Léman
shape. Maybe I should have given Floxmax another chance? One thing is
certain: I didn't drink enough water after the first catheterisation
(an out of hours emergency with a nurse doing the job); I continued
with my normal daily input of about 1.7L fluid. Not enough: the hospital
staff didn't ram it home as they did on 1 Feb (urology experts this
time). I didn't stand a chance on my own on 1 Feb, after that sensational
clogging-up over the period since 18 January.
Finally, one odd sensation continues. I regularly get the urge to urinate,
even with the catheter in place. I have to go to the toilet: often nothing
comes down outside the catheter; but sometimes it's a teaspoon
worth; and on other occasions as much as 50-100ml. For the latter if
you don't get to the toilet in time you have a real mess on your hands.
So, even with a catheter, I cannot be too far away from a toilet - just
in case. So much for 'spasms' and 'Urgency'! (The latter two problems
were still with me pre-Easter in March - when I put the set of three
emails up on the website.)
Email
to readers, friends and my family (9 March)
Back home now after the TURP operation and all appears to be going well
with the 'flow' (alas two litres voided during the night, every night).
The immediate hours after the two-hour brought a very serious crisis.
My 160gm vascular prostate (four times the normal size if blokes
my age; now no more jokes about the Guinness Book of Records please
Liz) and its wretchedly high number blood vessels proved to be real
sod. Pints of 'heated' blood were needed (haemoglobin levels fell dramatically,
by over 60%); also plasma; and, over 36 hours, 50 litres of saline were
pushed though my bladder. Plus other things two; into various inlets
into my body!
A 'real sod'? That was a gross understatement.. Even now though I can
see the funny side of some 'happenings': being tethered, dinghy-like,
to eight points around the bed, either taking readings or feeding me
with a handful of essential musts. I couldn't escape that's for sure!
Other laughs followed when just three attachments meant I could get
up but go no further than my bedside: in the main to cope with sudden
'spasms', coupled with 'urgency' voidings of urine (plus blood) outside
the three-way catheter (hope that makes you wince Brian) I had been
wearing for three days. (I had got used to those 'spasms' in the weeks
before the op.) One spasm at the hospital produced 400ml in no time
at all - like Niagara Falls. If I had remained in the bed I would have
floated away to the nearby River Avon.
One
'benefit' of the op (what follows would never have won any 'sales order'
in past decades) is that there's a mass of tissue available for 'histology':
that means in a few days I shall be given an up-date of how many cancer
cells are in the prostate and, most importantly, the Gleason 'Score',
or 'Rating', which tells you the 'aggressiveness' of the things. Anyway,
whatever, I shall have to continue keeping all battened down as best
I can.
Final
chuckle: I have restarted Pelvic Floor Exercises (what are they? asks
Jim: tell him Jane). First the 'Lift' - 'tighten as hard as you can
for as long as you can'; followed by the 'Wink' - 'only held for a second
and repeated quickly 5-10 times'. Finally, the 'Trick': do a couple
before you cough, sneeze or laugh'. All you blokes must be mystified:
ask the lady in your life. Real reason for this 'exercises'? To take
control of both 'urgency' and to ensure 'no lack of control'. So there!
Keep
smiling! Enjoy life! Keep your fingers crossed or anything else that's
handy: the latter is called the 'Pump' exercise (no, I'm not going to
explain Maril).
Email
to readers, friends and my family (18 March)
Progressing well at home. Pelvic Floor Exercises are still a priority.
'Urgency' is still a problem. Winning but lots more 'Lifts', 'Winks'
and 'Tricks' needed over the coming weeks before I can get a secure,
regular royal 'flush' every time.
The 'histology'? Alas, bad news. The Gleason 'Rating' or 'Score'
couldn't have been much worse. On a scale of 2-10 my score is 9. I'll
not go into detail but a summary would be: two of the most prominent
cell patterns extracted in the recent bore-out have been examined by
a pathologist and, in my case, a score of 4+5=9 emerged. In 1999, when
the original cystoscopy was done, the biopsy then gave a score of 3+3=6.
Both 4 and 5 are 'poorly differentiated' cells. QED: as aggressive as
they come.
The most disappointing aspect of the last two months is the out-of-the-blue
'vascularity' of my prostate (excessive blood supply). This is
the last thing you want in the gland when you know cancer cells
are about. How, when and why this has happened is now neither here nor
there. It's a fait accompli! I'm convinced it is all to do with
the body's immune system and the vital Th1 and Th2 cells and the two
different jobs they do. (Thymus-derived helper cell type 1 and type
2.) In my case prostate gland inflammation, infection and damage, both
long and short-term, prompts the body into healing mode, lowering Th1
levels to allow 'repairs' to take place. If cancer cells are lurking
this is bad news, particularly as Th2 cells proliferate, creating new
blood vessels around damaged tissue. They allow the cancer cells to
grow and spread. That's why I've been taking a 300mg dissolvable aspirin
every day for some time. Now I'm taking three; I wish I had earlier.
(If any of you are interested refer to the article called 'Cancer's
Missing Link' in this section of my site, under Author).
Anyway,
let's be positive. My urologist and oncologist, with my agreement, are
undertaking the following treatment 'plan'. Immediately after Easter
I start a 'Maximum Androgen Blockade' for three months. I continue with
Casodex (which blocks testosterone from the prostate) and I start again
with Zoladex (a monthly implant which prevents the body from making
testosterone and other 'androgens'). QED: the blockade keeps testosterone
from both the prostate and the cancer cells.
The
aim is to try to reduce the size of my prostate even further over three
months (April to June). The gland has already lost a big part of its
'interior': 100gm were removed in the recent op, leaving 60+gm. Then
the 'plan' is to use 'conformal radiotherapy' to see if we can kill-off
the remaining cancer cells. I explained all this some years ago on this
website: see the very start of this now long chapter.
Keep
fingers crossed! Be sure that I will be like the 'frog' in the 'Don't
Ever Give Up!' Cartoon. (I've sent hundreds of copies to my readers
over the years.)
Three
important observations
1) The 'vascularity' (copious blood vessels) of my prostate came as
a shock: for me and all the medics providing advice and care. PSA readings
gave no clue. What should be standard treatment is constant monitoring
of the condition, especially for large prostates: for example
the use of endoscopy investigations in the prostate; or more detailed
ultrasounds perhaps (you'll not be surprised to read that I, eventually,
had to pay privately for an ultrasound to be done; the pressure, and
backlog, on NHS equipment is huge). Does anyone have ideas how this
could be done? E-mail Richard
A copious
blood supply is the LAST thing cancer cells need! What the latter
need is a supply of angio genesis inhibitors (agi: which stop the creation
of new blood vessels). See Soya Isoflavones in 'My Diet' (in this drop-down
menu list). The latter have come too late to really help me during the
last year or two - but, over a lifetime, they have benefited, massively,
all Far Eastern men and women with cancers of the prostate and breast.
I know work is being done in trying to create 'agi' drugs. At the moment
Thalidomide, a very potent 'agi'(the cause of all the terrible deformed
limbs in children during the early 60s) is being used but only for advanced
cancers.
2) Taking
the gamble to stop Casodex in August 2003 (see earlier) for six months
was a big mistake on my part, but supported by the medics looking after
me. All we had in mind were the cancer cells; no account was taken of
the impact in providing testosterone to the prostate - which allowed
the gland to grow even bigger.
3) Somewhere
along the line all the above links back to the Th1/Th2 cells mentioned
earlier. Th2 cells must have created the steep increase in 'vascularity'
and, QED, the stepped-up aggressiveness of the cancer cells. (I've had
a long history of inflammation and infection in the prostate over 25
years, ever since I started sitting for such long periods in a car carrying
out all the myriad research I've been doing!)
End
May 2005
First, the humdrum news. The TURP operation has been a success. Two
weeks after the op I stopped taking Oxybutynin (to help the urgency
problems). Bleeding eventually stopped 10 weeks after the op. By then
waterworks 'performance' was hugely improved - more like one's younger
days. For so long, from mid-January when the first catheter was put
in place, proper exercise was a pipe-dream; but after the bleeding stopped
I was able to work hard at restoring muscle power. At the end of May
I felt 100% fit again; and looked it too. The Zoladex/Casodex combination
continues. One major caveat: has the major loss of blood from the prostate
gland, starting in mid-January, carried the aggressive cells to other
parts of my body?
End June 2005
Now the news I've been apprehensive about since the end of January
I've had three 'scans' in the last few weeks: first a 'CT scan', followed
by an 'Ultrasound scan', both at Warwick Hospital; and finally a 'Gamma
camera' bone scan' at Coventry's Walsgrave Hospital.
The CT scan confirmed the need for a bone scan. The Ultrasound confirmed
that the overall size of the prostate gland remained big, despite the
100gm removed during the TURP op, 7cm at the widest diameter; and the
prostate 'capsule' had been breached by a 'tumour'. The bone scan, as
you have guessed, brought the worst news of all.
The cancer cells had indeed escaped: significant 'spots' could be seen
on ribs; much larger areas had developed on the bottom of the spine;
and a bigger amount of cancer had taken hold in a corner of the pelvic
area.
How can I relate the eventual outcome of this hammer-blow news? A reader
friend, like so many of you, on hearing from me in early June of this
possibility, sent me an email: 'I am sad to read that the prostate cancer
is moving towards your bones. All the very best for 17/6/05 and I hope
the Good Lord will reject any indication that you wish to have an appointment
with him!!'
Well, the 'appointment' looks likely to come sooner or later - but certainly
much earlier than anyone would ever want to meet 'the Good Lord'. I
shall have to be the 'frog' in the cartoon: fighting like a dervish
to stop the heron swallowing me! Radiotherapy, conformal or otherwise,
is pointless; that is a non-starter. Zoladex, with or without Casodex,
initially remains the only treatment to keep the bone cancer quiet.
I shall have monthly PSA blood tests to determine the progress of the
ongoing hormone therapy (on 17 June my PSA was 6.6; not much lower than
the 8.7 last November). Some time soon I shall meet Prof. Nick James
at the Queen Elizabeth Hospital in Brum to determine if any other 'novel'
treatments, at the clinical trial stage, may be able to help (like e-coli).
Chemotherapy will be another toxic possibility. As will Thalidomide,
the ultimate and strongest possible angiogenesis inhibitor; Prof. Stewart
at Leicester Hospital uses this for advanced cancers.
I shall continue to keep fighting fit: and I shall continue with my
régime - with absolutely no dairy produce these days.
My greatest sadness is the burden my dear Carol has already had to carry
and will increasingly have to continue to do so in the months to come.
She does not deserve such massive misfortune. Sadness, too, for my family
- and especially Keith, a real Rock of Gibraltar brother. All of you
I know will continue to be 'seconds' in the ring, encouraging and ensuring
this frog scraps to the bitter end. Please do not feel unhappy: be positive;
keep well; and continue to enjoy life. Carol and I will do so, that's
for sure. More reports, at the end of every two months, will follow.
Observations: these cannot change past events but will interest you
nevertheless.
This month I read the following on the Mayo Clinic website: 'A small
percentage of prostate cancers don't lead to elevated PSA. In these
cases PSA level may be normal or even low, despite the prostate cancer.
Some scientists believe these have more genetic mutations than others
and allow this form of prostate cancer to grow and spread more quickly.
One group of researchers found that PSA helps slow the growth of prostate
cancer in laboratory studies by slowing the growth of new blood vessels
(angiogenesis) that cancer needs to survive. This may explain why prostate
cancers that don 't produce PSA tend to grow and spread more rapidly
than prostate cancers that do produce PSA. More research is needed to
determine prognosis and treatment.' The above fits my 'case' over the
last few years to a tee: 100% spot-on!
The NHS. In July 2002 I asked for an Ultrasound scan, to check the gland
size. A three-line letter confirmed the 'volume is graded at 139mls'
(gm). The letter continued: 'In one spot in the right lateral lobe,
there is a swelling which breaks the capsule. This will be discussed
at the next Multi Disciplinary Meeting.' It was and no undue concern
was expressed. At the time my PSA was a low 3.6.
Despite the fact that I have seen consultants, consecutively a urologist
and oncologist, every three months for the last six years, nothing was
done post July 2002 to assess prostate gland - until I pressed hard
for a further Ultrasound test in January 2005.
The NHS is a '10-minute service'. Pressures, stress and sheer volume
of work (three incoming phone calls came when my oncologist broke the
bone scan's 'very bad news'; and the meeting started an hour late!)
prevent consultants diligently managing their patients problems and
constantly reviewing the treatments needed.
Now it's pretty obvious that further Ultrasounds should have followed
in both 2003 and 2004; plus the use of endoscopy, which would have shown
how vascular the gland was becoming (excessive blood vessels, the single
worst situation as blood provides the essential oxygen for cancer cells
to thrive and become ultra aggressive).
No wonder then that Japanese men, for example, with their life-long
diet of soya (Nature's weak but best angiogenesis inhibitor), tend to
have far fewer aggressive prostate cancers (they certainly have the
same number of cells; autopsies prove that). My two to three years on
a similar régime is like spitting into the wind - but I shall
continue it with a vengeance, especially the elimination of all dairy
produce.
End August 2005
Ive had four rewarding consultations during July and
August: first in Coventry with my oncologist Dr Caroline Humber; followed
by two with Professor Will Steward at University Hospital in Leicester
and Professor Nick James at University Hospital in Birmingham; and then
a final recap meeting with Dr Humber.
The encouraging news is that I have several optional treatments - all
legally and currently available as prescription drugs. However, first,
let me describe two important medical terms.
A. Hormone-related therapy Cancer of the prostate depends on testosterone
for its growth. Androgen drugs (also called pituitary down-regulators),
such as Zoladex or Prostap, act directly on the pituitary gland and
prevent a signal reaching the testes, which manufacture testosterone.
Casodex and Cyproterone are anti-androgen drugs which stop (or block)
testosterone from reaching the cancer cells in the prostate. Note: testosterone
is still made. (Ive had both Zoladex, in 1999/2000 and the last
five months, and Casodex in 2001-2004.)
Hormonal drugs like Stilboestrol release man-made oestrogen which prevents
a signal from the pituitary reaching the testes.
B. Hormone-refractory prostate cancer This can occur some years after
successful use of the above drugs. The cancer sells eventually find
ways (refraction) of growing and spreading, helped by the blood supply,
without the need for testosterone. Often the cancer spreads to the bones:
as a result patients are then left with fewer treatment options for
the disease. Hormone-refractory makes any drug, on its own,
ineffective.
Available treatments for my bone cancer are (in the order I would use
them):
1. Combined androgen drugs like Zoladex and Casodex, both
at maximum doses.
2. Alternative hormone therapy - changed to make the cancer cells think
again. One example would be Stilboestrol combined with a steroid like
Prednisolene or Hydrocortisone (both corticosteroids).
3 Chemotherapy where several drugs and minerals are used: think of the
mix like a cocktail - the contents and quantities put in the shaker
depend on the patients needs. An example: the toxic Docetaxel
or Taxotere drugs mixed with the likes of Tetracycline, Thalidomide,
Vitamin D, Melatonin and many others.
4. Bone-targeted therapies: Bisphosphonates (to strengthen bones) or
Radio-isotopes.
5 The new Tyrosine Kinases Inhibitors (angiogenesis inhibitors) which,
though they cannot kill cancer cells, do stop blood vessels forming,
the latter needed for the cells to flourish and spread. These now replace
Thalidomide. Three years ago Prof Steward gave me the details of TKIs
when they were at the phase II stage of a clinical trial.
The last two words give you a clue to the treatment I have chosen instead
of those listed above. Professor James has suggested, and I have accepted,
that I join a current phase II clinical trial of an AztraZenica
product - ZD4054 (no name yet).
What is ZD4054? Many cancers make substances that help their growth.
ZD4054 is an investigational new drug that blocks one of these substances
called endothelin-1. Experiments have shown that blocking endothelin-1
reduces the spread of cancer to bone and for the cancers that have already
spread to the bone, reduce bone pain.
By coincidence I already know of Abbott Laboratories Xinlay drug
- which has just been given permission by the U.S. Food and Drug Administration
to make the drug available to men with late-stage prostate cancer (in
the bones) which does not respond to hormone therapy (like me) - even
though the drug is not yet fully approved.
The drug is akin to ZD4054. Indeed I wonder is there is some link between
the two drugs , though not yet official and out in the open! Abbott
say their drug is: a critical step in our goal of making new therapies
that are less toxic. The same seems to apply to ZD4054.. Abbott
continue by claiming Xinlay is an investigational, oral, once
daily, non-hormonal, non-chemotherapy, anti-cancer agent that belongs
to a class of compounds known as endothelin-A receptor antagonists.
They antagonise (block) the effect of endothelin-1 (ET-1), one of the
proteins thought to be involved in the stimulation of the spread of
cancer cells. All those words apply equally to ZD4054!
( Apparently clinical trials for use of the drug earlier in the disease
are underway in the States. Also work is being done to measure the drugs
effectiveness with other cancers. No wonder then that the Bank of America
Securities team believe that, once the drug is approved in late 2005,
Xinlay sales will reach $300 million in 2006 and ultimately $1.5-2.0
billion annually.)
So, all good news - if the two drugs prove to be that effective! I have
two months of tests, scans and other pre-treatment examinations before
I start the trial at the end of October. The sole debit is that one
in three of the patients taking part in the UK trial, just 42 of them,
will be taking daily placebo pills!
Abbott also say For patients where prostate cancer spreads to
other organs (including the bones), it remains incurable. That
may well be but there are plenty of ways of fighting the beast.
Some of you have seen me recently. You already know that my contribution
to the scrap is two-fold: to keep super fit and to stick like a limpet
to my terrific food régime. The fact is I look and feel fitter
than Ive been at any time since 1960! Keep your fingers crossed
for mr.
Expect the next update at the end of the year.
End January 2006
I started the clinical trial of ZD4054 on 21 October 2005. The
seven week delay came as a result of waiting for scans and blood tests
to be carried out. In addition three PSA readings had to be done, each
of which entailed a three-week gap before the next. One of the conditions
for acceptance on the trial was that PSA readings were rising
to prove hormone refraction was taking place (i.e. the body twigs
how to circumvent the monthly Zoladex injection started in mid 2005).
You guessed right: the scores rose!
A CT scan was done at the trial start (21/10/05). A further CT scan
followed at week 12 (12/01/06). At weeks 4 and 8 further blood tests
were carried out.
Sadly, I had to abandon the trial following the CT scan at week 12.
In the words of Professor James: the disease has progressed.
Comparing the two CT scans proved the point. Specifically thee lymph
nodes had grown in size (one from three cm to four). So much for trying
to guess if I was on a placebo or the real thing.
For the record the PSA scores had risen from 6.6 last summer to 61 at
week 8; as yet Ive not had the week 12 score but my guess is that
it will be in excess of 100.
(Incidentally, earlier bad news came in a press release from the U.S.
Food and Drug Administration: they stopped Abbott using its version
of the trial drug in the U.S.)
I have now started Available treatment number 1 as
described in the End August 2005 update (already sent to you by email/letter;
and also on my website*). This is tagged the maximum androgen blockade
Zoladex and Casodex taken together.

I continue to look and feel well; and to be Tiger Frog Positive.
Ill be in touch again in early summer.
1June 2006
The maximum androgen blockade, Zoladex and Casodex together, have failed. Not surprising really, as my PSA has risen in s sharp line from 61 on 15 December to 255 at 25 May 2006. WE should have abandoned the ‘blockade’ on 20 April this year, when the PSA read 187; but the ‘registrar’ (she was a wishful thinker!) thought I should try the drug combination for another six weeks.
On 1 June I visited the Queen Elizabeth Hospital in Birmingham but, alas, Professor James was not there (I last saw him on 12 January). After an hour spent updating a new doctor, who then updated a new ‘registrar’, followed by me updating the latter, we agreed to bypass the stilboestrol and prednisolone (a corticosteriod) option and go ahead with chemotherapy (Docetaxel, otherwise known as Taxotere).
However, I must await six-eight weeks because I must allow Casodex to disappear from my system; Zoladex, amazingly for me as it has been a major failure since last summer, will continue.
So, I’ll start the chemo towards the end of July. I hope to see Professor James on 13 July to confirm the choice made by his team. (Bone pain has started to rear its ugly head, but not too seriously. The chemo should help me combat this, especially if the pain increases.)
