Presentation for SDBTT Astro Fund Brain Tumour Information Day

 

17 March 2008

 

 

Hope for the Future:

Alliances and Promising Areas of Research

 

 

 

 

SLIDE 1

 

Hello everyone, and thank you to the Samantha Dickson Brain Tumour Trust and the  Astro Fund for inviting me to speak at this excellent Brain Tumour Information Day.  It’s good to finally meet so many of the people who are participants in the online support group.

 

My name is Kathy Oliver and I’m the Secretary of the International Brain Tumour Alliance which is a worldwide coalition of brain tumour support, advocacy and information groups.

 

I am neither a doctor, nurse nor researcher. 

 

But one January night four years ago, and in the six seconds it took for a neuro-surgeon to say to my husband and me: “I’m so sorry your son has a brain tumour” we were catapulted into a strange new place where, never in our wildest dreams, we ever thought we would be.  

 

 

We were sitting in a tiny, windowless room in a London hospital when news of my son’s brain tumour was given to us, but we may as well have been sitting on a planet in outer space.  We immediately felt like travellers in a strange and surreal landscape. 

 

We didn’t speak the language.  We didn’t know how to get from A to B.  But most of all, we were filled with dread of the unknown road ahead.  We had no map, no compass, no anchor to steady us.

 

We realised immediately, as I’m sure did all of you, that there would be many challenges in this new place. 

 

But despite some of the more difficult challenges that all of us in this room face, I think it’s important not to lose sight of the fact that there are beginning to be reasons for realistic hope when you are catapulted, as we all were, into that strange and foreign land.

 

 

SLIDE 2

 

First, let me introduce you to a promising equation.  I hope by the end of this presentation that we’ll be able to understand it, after taking a look at not only promising therapies but promising alliances as well.  So I’d like you to think about this:

 

What does the globe, a pair of old trainers, a researcher, an operating theatre, a small capsule, a brick wall, a guy with a bandana and a guitar, a new day and a moonlit night have to do with brain tumours?

 

 

SLIDE 3

 

Well, let’s start with the globe.

 

Because of their challenging nature, their rarity, and the way they can affect people, brain tumours require a truly global focus of attention in order to raise awareness of this disease.  New alliances need to be formed because no one person or institution can afford to be an island when it comes to treating brain tumours.  There is power, strength and combined knowledge in alliances.  And from the patient perspective, there’s less of a feeling of being alone when one can become part of a concerted effort to make things better.

 

SLIDE 4

 

This is the reason why the International Brain Tumour Alliance – the IBTA – was established in 2005 during the World Federation of Neuro-Oncology and European Association of Neuro-Oncology conference in Edinburgh. 

 

 

About 50 people - including patients, clinicians, researchers, scientists, caregivers and brain tumour charity officials from eleven different countries -  came together to establish a coalition of like-minded people, all dedicated to improving the situation for all those whose lives have been touched by a brain tumour, despite the miles between them, the different time zones and the different cultures.

 

As we all know, brain tumours don’t discriminate by sex, race, geography, age, religion or class.  An enemy as clever as a brain tumour can only be vanquished by a concerted global effort.

 

SLIDE 5

 

So the IBTA was established to assist with this goal.

 

As I said, we’re an international alliance.

 

We’re a non-governmental, not-for-profit organisation.

 

And we try to provide a louder voice for those living with a brain tumour.

 

 

SLIDE 6

 

We seek a wider public recognition of the specific challenges brain tumours present.

 

We offer our assistance and expertise.

 

We encourage the formation of brain tumour support groups in countries where they don’t yet exist.

 

We advocate for access to promising new treatments.

 

And we try to instil a greater measure of hope within the international brain tumour community.

 

 

SLIDE 7

 

One of the ways we learn about promising new treatments is for the IBTA Chair, Denis Strangman, and me to attend brain tumour conferences where we’re able to hear presentations on the latest research and clinical trial results.  Attending these conferences, we’re also able to chat informally with leading clinicians from around the world and establish good contacts with them.  We also sometimes do presentations at these conferences in order to put forward the patient perspective and to ensure that medical professionals are aware of our concerns and needs as patients and caregivers on this journey. 

 

So here we have a few photographs of some of the conferences and meetings Denis and I have attended in the last few years.

 

I never ever thought I’d learn how to say the words “brain tumour” in various foreign languages.  But in speaking to or emailing brain tumour patients from Western and Eastern Europe, Africa, Russia, America, Canada, Australia, New Zealand and beyond, there’s one thing I have learned.  Brain tumours spell challenge in any language.

 

 

SLIDE 8

 

So, where do these old trainers come into the picture and what do they have to do with alliances?

 

 

SLIDE 9

 

Well, in 2007 – and as part of its awareness raising initiative – the IBTA launched the inaugural Walk Around the World for Brain Tumours and the International Brain Tumour Awareness Week.

 

Our idea was to encourage patients, caregivers, families and all those involved professionally in the field of brain tumours to unite across country borders in the last week of October and do some kind of project to raise awareness of this disease.

 

The main project was the Walk Around the World for Brain Tumours whereby brain tumour charities and groups organised sponsored walks.  The funds raised by these walks were directed to local brain tumour research institutions or groups who provide support for brain tumour patients.  Not a penny from the walks or associated activities went to the IBTA.

 

But the mileage achieved was donated to the IBTA in an effort to reach our target goal of 40,000 kms which is once around the world at the Equator.  Walks could take place any time in 2007 up to the end of the Awareness Week.

 

 

SLIDE 10

 

So in 2007 there were 83 walks in 18 countries and regions.  Twenty-two thousand people walked around the world for brain tumours.  Walks ranged from those involving just one person to a walk involving 4,000 people.  And from just 14 walks for which we know the amounts collected, approximately $1.6 million US Dollars was raised for brain tumour research and support activities. 

 

 

SLIDE 11

 

We set out to achieve 40,000 kms – once around the world at the Equator.

 

In the end over 114,000 kms were walked – that’s two and a half times around the world, not just once!

 

 

SLIDE 12

 

And here are just a few of the photographs from the Walk Around the World album.  If any of you sitting in this auditorium today are feeling lost and alone, please do take a good look at this slide because it will demonstrate that you aren’t alone and that there are people all around the world who really care about helping you and working hard together to raise awareness of brain tumours.

 

From the Himalayas to Holkham Hall in Norfolk where the Astro Fund for example held a Walk last October, from America to Hong Kong, people united to get the message across that we must have more done for brain tumour patients.

 

 

SLIDE 13

 

We’re repeating the International Awareness Week and the World Walk this year.  The dates are Sunday, 26 October to Saturday, 1 November 2008. We already have the support of over 100 brain tumour relevant organisations around the world.   And here you see them listed – a solid block of text on this slide representing thousands of people who are supporting brain tumour patients around the planet.

 

 

SLIDE 14

 

And now for the next part of the equation – the research, surgeons, clinicians and therapies.

 

I should add here that my layman’s comments in this presentation aren’t in any way meant to constitute medical or other advice or recommendations.  Regardless of information appearing in a presentation such as this, medical professionals should always be consulted before any decision is even considered or any course of treatment is undertaken. Also, therapies, devices, treatment approaches and other information mentioned in this presentation doesn’t necessarily imply endorsement by the IBTA.

 

SLIDE 15

 

Following on from decades of very little progress in the field of brain tumour research and treatment, recent years have seen new improvements that have certainly changed the landscape of this disease.

 

Many questions are being considered.

 

The goal in answering these questions is to find a cure for brain tumours…or at least to be able to manage them as a chronic condition.

 

 

SLIDE 16

 

There are now new ways of looking at brain tumours.

 

For example: -

 

Is a glioblastoma multiforme one type of brain tumour or does it represent a variety of different malignant gliomas which need to be identified?

 

How should low grade gliomas be treated?

 

What role do stem cells play?

 

What combination therapies will emerge and what role will they play?

 

What will constitute “new best practice”?

 

 

SLIDE 17

 

Scientists and clinicians are now looking, for example, at genetic markers to see what makes one tumour different – or similar – to another.  Use of these genetic markers, such as the loss of chromosomes 1p and 19q, the status of an enzyme called MGMT and various other repair and signalling genes may help doctors to better identify what elements they need to target.  I’ll mention another aspect of genetic markers later in my presentation.

 

I think the days are gone when it was believed that there might be one magic bullet to treat brain tumours.

 

Nowadays, clinicians are looking at combinations of therapies which have a synergistic activity and a greater response than if they had been given on their own as single agents.  This is known as the “multi-modal approach” or the “cocktail approach”.

 

 

SLIDE 18

 

There are now a growing number of exciting and hopefully promising areas and therapeutic agents which are under examination in labs and clinics.

 

 

SLIDE 19

 

Perhaps one of the biggest reasons to be hopeful is that today more and more laboratories and institutions are researching brain tumours.  This may be due, in fairly substantial part to increased advocacy, awareness raising and fund raising on the part of brain tumour charities and other patient organisations who often provide start-up grant funding for research projects.

 

Research and treating institutions are also forming alliances so as to share knowledge in the hope of better outcomes for brain tumour patients.  One example of this would be Brain Tumour Northwest which involves the Universities of Central Lancashire and Wolverhampton together with the Lancashire Teaching Hospitals NHS Trust, Manchester, Keele and Sheffield and their associated NHS Trusts.

Another example would be the centre of excellence for brain tumour research at the University of Portsmouth which is collaborating with a number of other institutions.

 

In various institutions and labs around the world, researchers are looking at such things as the mechanisms of brain tumour growth and control, the development of targeted therapies and the study of immunotherapies.

 

 

SLIDE 20

 

On the imaging front…

 

Apart from CT scans and standard MRIs, doctors now have a new arsenal of imaging techniques which can give them helpful additional information about brain tumours:

 

With PET scanning and SPECT scanning, doctors can assess metabolic activity in the brain – that is, the way it converts glucose into energy.  PET scanning can help to determine the difference between a benign brain tumour and a malignant one because malignant tumours are more metabolically active than benign tumours.

 

Perfusion MRI can also be helpful in evaluating cerebral blood flow.  Malignant brain tumours have increased blood volume which corresponds to a higher degree of vascularity.  Some doctors use Perfusion MRI to help them distinguish pseudo progression from tumour progression.

 

SLIDE 21

 

On the surgery front…

 

Neuro-surgical techniques and equipment have come on tremendously and continue to improve, resulting in better efficiency and safer outcomes.

 

Awake craniotomy, where suitable, can be used when tumours involve a delicate or “eloquent” area of the brain.

 

Image guided navigation during surgery can help a surgeon find the tumour target with millimetre accuracy.

 

Intra-operative MRI allows for scanning at any time during neuro-surgery to help monitor the progress of an operation.

 

New developments in surgically-placed devices and therapies - such as catheters for locally delivered drugs straight to the tumour site and chemo-impregnated wafers - are being refined.

 

 

SLIDE 22

 

On the radiotherapy front…

 

In addition to newer ways of giving radiotherapy to certain kinds of brain tumours such as 3D conformal radiation therapy, stereotactic radiotherapy and radio surgery (also known as gamma knife), doctors now combine chemotherapy with radiotherapy.  An example of this is temozolomide which is first given for six weeks alongside the radiotherapy schedule and then continued on its own for a time after radiotherapy. 

 

A landmark multi-centre, international clinical trial, the results for which were announced in 2005, proved that temozolomide has a synergistic effect on radiotherapy and, together with its post radiotherapy course, results in extended survival in patients with newly diagnosed glioblastoma multiforme.

 

And thanks to the efforts of the alliance of UK brain tumour patient organisations, clinicians and industry who campaigned for eighteen months to get this groundbreaking therapy subsidised on the NHS in England and Wales, as of September 2007 newly diagnosed glioblastoma multiforme brain tumour patients can access this combination therapy for free, provided they meet certain criteria.

 

SLIDE 23

 

On the chemotherapy and other agents front…

 

 

Although it would be premature to say that a whole galaxy of treatments is emerging for brain tumours, it would be fair to say that progress is being made in the way of a number of tongue-twister-named treatments which are showing efficacy in clinical trials.

 

Bevacizumab (otherwise known as Avastin), cilengitide, enzastaurin, and cediranib (otherwise know as Recentin) are what are called anti-angiogenesis agents that target the greatly increased number of blood vessels which feed a tumour. In effect these treatments starve the tumour of their blood supply, their oxygen and their vital nutrients.  These drugs block a protein called VEGF, one of the factors that brain tumours use to build new blood vessels. These drugs seem to be particularly promising and are currently the subject of various clinical trials around the world.

 

Novel approaches to malignant gliomas include drugs that stop cell division.  These include tamoxifen, irinotecan used in combination with bevacizumab, and other therapies.

 

Immunotherapy seems to hold promise too.  There are two different approaches.  One involves so-called “off the shelf” immunotherapies that hunt out tumour cells which express a particular protein.  The other approach involves “autologous immunotherapies” which are individualised by being made from a patient’s own resected tumour tissue and that zero in on specific proteins which are expressed by a patient’s own tumour.  There is also a suggestion that immunotherapy might be given in combination with chemotherapy to enhance the effectiveness of chemo.

 

Brain tumour stem cells, the so-called “generals” of the invading tumour cell army, are also being studied so that specific features of these cells can be identified and targeted with suitable treatments. 

 

So that is all looking pretty good.

 

 

SLIDE 24

 

But now we come to the brick wall in the equation.  Unfortunately, this a bit of a negative aspect amongst all this positivity but one it’s important to be aware of.

 

SLIDE 25

 

First…

 

With all of these promising treatment advances in the developmental pipeline, we have to be aware that regulatory and rationing bodies, such as, for example, the National Institute for Health and Clinical Excellence (NICE) here in the UK or the FDA in the US or the Pharmaceutical Benefits Advisory Committee in Australia, or Pharmac in New Zealand could possibly slow down or even prohibit access to new therapies. 

 

 

To be fair, NICE has recently adopted a faster, hopefully more efficient system of appraising new therapies.  But their mechanism for appraising new treatments remains based on whether or not a treatment is cost-effective to the exclusion of considering other factors such as the value of even a limited extended survival with good quality of life and the cost benefit a caregiver can bring to the equation. 

 

Cutting edge therapies for brain tumours don’t come cheap.  Single therapies are expensive and we’re now seeing combination therapies of two or more of these costly agents.  And while governments claim to have the willingness and strength to improve cancer survival rates across Europe, the pockets of some can be very shallow indeed when it comes to allowing desperate patients access to these promising new therapies on government-subsidised national health services.

 

Second…

 

I spoke a little while ago about use of genetic markers to determine targeted therapies for brain tumour treatment.  As patient advocates, we need to be aware that this same information could be used by regulatory bodies to implement a poorly-founded method of discrimination against patients.  So before access limiting methods based on genetic marker tests are incorporated in any National Health Service policy for brain tumour therapy, the means of assessing these genetic markers must be rigorously examined and validated on an internationally consistent basis.

 

Indeed, leading European neuro-specialists Professor Martin van de Bent and Dr Johan Kros published a paper on this very issue a few months ago.  They said – and I quote - : “…the application of these tests is far from straightforward, and certain standards are required before any test can be introduced into the daily management of patients.”

 

 

SLIDE 26

 

Additionally, governments and major international and national cancer control organisations have prioritised prevention, screening and healthy living campaigns in the fight against cancer.

 

These are all excellent initiatives of course. 

 

But not every cancer can be helped by this approach.

 

SLIDE 27

 

As for brain tumours and prevention?

 

Well, the cause of most primary brain tumours is generally unknown so without knowing their causes, there can be no prevention programmes for brain tumours.

 

 

Brain tumours mostly appear to attack at random so universal screening for them is unrealistic.

 

Anti-smoking campaigns surely save more lives from lung cancer.  Weight control and healthy eating might also help cut some cancers occurring.  But there appear to be no such lifestyle shifts in order to avoid a brain tumour.

 

 

SLIDE 28

 

And so we come to the penultimate part of the equation – a guy with a bandanna and a guitar.

 

This is David M Bailey, an American singer/songwriter who was diagnosed nearly a dozen years ago with a glioblastoma multiforme brain tumour and given six months to live.  You can read more about him on his website. I’ll show the address in a minute. 

 

Eleven years, 16 CDs, 44 American state tours and a British concert series later, David and his music are very much alive and well. 

 

 

SLIDE 29

 

David and Matthew, pictured here in the lower left photograph are two very long term survivors of a brain tumour and are symbols of hope. 

 

 

SLIDE 30

 

And for those in need of a little hope on this journey, there are other inspirational survivor stories on the Virtual Trials website at www.virtualtrials.com  one of the most respected and best sites on the internet for keeping up to date with brain tumour treatments and background information.

 

Hope is vital. 

 

One of Australia’s, and indeed the world’s, most eminent head and neck cancer surgeons, Professor Chris O’Brien, was recently diagnosed with a glioblastoma.  As first a clinician and now himself a brain tumour patient, Chris voiced his philosophy in a recent newspaper interview.

 

He said: “…hope, not defeat should always be the starting point, no matter someone’s diagnosis.”

 

In seeking to define “hope”, the American doctor Jerome Groopman, writes in his book “The Anatomy of Hope”:

 

“Although there is no uniform definition of hope, I found one that seemed to capture what my patients had taught me.  Hope is the elevating feeling we experience when we see – in the mind’s eye – a path to a better future.  Hope acknowledges the significant obstacles and deep pitfalls along that path.  True hope has no room for delusion. …hope gives us the courage to confront our circumstances and the capacity to surmount them.”

 

I’d like to add here that to the oncologists, researchers, nurses and associated healthcare professionals who battle around the globe to conquer brain tumours, we owe an enormous debt of gratitude.  From the bottom of our hearts, thank you. 

 

And so to the last part of the equation.

 

 

SLIDE 31

 

A sunrise and a moon.

 

As the mother of a brain tumour patient, I often remind myself that when our day ends and we go to sleep on this side of the world, a new day breaks on the other side of the globe, where people are just waking up to a new day in their laboratories, a new day in their surgeries and a new day in their wards and clinics.  Likewise when those on the other side of the world finish their day, we on this side are just beginning ours. 

 

Through alliances, partnerships, collaborations and coalitions, who knows what new brain tumour treatments might be discovered when daylight breaks in various corners of the world? 

 

So even while we sleep there is hope.

 

 

SLIDE 32

 

And so there you have it. The equation is completed – with Hope.

 

And to finish off today, we’d like to play you a DVD of David M Bailey performing one of his songs.  By the way, David will be returning to the UK for another series of concerts in October, in Southeastern England and Edinburgh.  Preliminary details are on David’s website.

 

SLIDE 33

 

Thank you all for listening.

 

 

SLIDE 34

 

Important note.

 

 

Play David Bailey’s DVD of Tucson to finish.
