| Hearing
of Professor Luigi Di Bella at the Commission of Social Affairs of the
House of Deputies (part two)
Antonio Saia -
As expected, your therapeutic method is arousing great hopes in our country,
maybe even some illusions; however it is arousing curiosity in me, as in
many other people, as a man, as a physician and as a representative of
the law.
We have no sure elements
to assess the efficacy of your treatment, to ascertain what kind of tumours
it is more efficacious with and useful for with respect to the traditional
therapies. To eliminate all doubts about our position, I would like to
say first of all that we believe that science has maade huge breakthroughs
in this field: tumours treated with hormonal therapies like Hodgkin's disease,
and some types of leukemia, can today be almost completely cured by resorting
to traditional methods. However, it is our duty to shed light on this issues
in order to meet the Italian patients and people's needs.
We must make sure that a
new possible way is investigated. Your words said extremely interesting
things; currently, the human body is already living with some tumours -
I am referring to benign tumours - so why don't we try and live with the
metastases of other tumours? We do not think it would be useful, however,
to neglect new ways that often made a complete recovery possible, such
as surgery: I am thinking of colon cancers where early diagnosis makes
it currently possible to obtain a recovery equal to 70 or 80%. Thus,
- this is our duty, too - we must prevent people, who could be cured well,
with tested and efficacious therapies, from beginning to use a method that
has not yet officially and finally been tested.
It is necessary to know
how this therapy works in order to understand whether it can actually be
useful even as regards a low percentage of tumours - it would be a very
important result, anyway - avoiding the opposite risk.
To do this I think it would
be necessary, Prof. Di Bella, to pull down the wall between you and your
collaborators on one side and the CUF (the Drugs Single Commission), the
Government and the Oncological Commission on the other. It would be necessary
to start a clinical control instead of a trial, because it is a fact that
tens of thousands of people are now following your therapeutic protocol.
We are very interested to
know the final outcome of such control and, to that end, we would like
to ask you to allow us to do it; we think it is fundamental for you
and your group to co-operate in the research and this is what we intend
to ask the Minister.
It is on behalf of those
patients to whom you devoted your life that we ask you to co-operate with
the minister, who is just using, and couldn't do otherwise, the facilities
and the regulations which have ruled this field up until today.
Vasco Giannotti - Many of
us - let me underscore that when I say “many of us” I am not speaking on
behalf of a specific group as I think that opposing a group against another
pertaining these issues would be childish and wrong - acted to grant you
the best possible conditions to demonstrate the efficacy of your method.
I am glad that we have now come to the real point of the whole question
that is trial, also thanks to your help (and I'd please ask you to be completely
helpful) and your measured attitude (and I hope that such an attitude will
continue - as we saw during most of the TV programme yesterday night).
The question that is of
great concern to me is the following: I understand that trials are not
easy to carry out; I would like to ask you - as I will ask the others -
what are the necessary things, the time required, what is needed to give
the citizens what they are asking for and that should be our duty as lawmakers
to provide, that is whether your method can test the efficacy and the effectiveness
of the results. I am asking you the rules, the time and the ways we need
to follow.
You outlined two concepts
that will stir much debate and this is a good thing. The first concept
is freedom of therapy: the citizen - as you said - must be properly informed
in order to decide along with his doctor the kind of treatment to carry
out. But you claimed, Mr. Professor, that for this freedom to be real it
is necessary for a doctor to know how to propose effective therapies. I
hope that your method, after the scientific trial (as proven by many facts),
may prove effective: this is what Italy is expecting.
The second concept you mentioned
is that of living with a tumour.
This is another fascinating
arguing point, but in this case too we must be careful: let's try and work
with wisdom and moderation, as you often told us.
Living together means to
keep into consideration all the results obtained. In my view the fact that
the mortality rate went from 70 down to 50% over the past twenty years
is a very important result, too (I am here referring to the official data
so I am open to denials). Finally, there is the great chapter that you
mentioned concerning the quality of life: this is another important point.
I think then that the members
of the Parliament's task is not to speak of the various methods; the essential
point consists in providing the citizen with the best possible treatments
and that is why the time and the method of the trial are important.
Piergiorgio Massidda - I
agree that no one can deal with a problem concerning an individual from
a political standpoint, although there may be a higher or lower sensibility.
As I am one of the signatories
of the agenda which was rejected when the financial law was examined, I
am clearly a supporter of your needs and requests. However, as lawmakers,
we also have other duties and, among them, in this particular moment, that
of lowering the tones. We are assessing with you the effectiveness of the
therapy you developed but, at the same time, we cannot throw discredit
on other therapies which have given extremely good results so far. We fear
that today's debate may create problems for the sick and protecting this
principle is our duty.
Here is the reason for this
hearing and for our interest: as lawmakers, we must help the citizens,
and you researchers must clearly provide the therapeutic arsenal with as
many weapons as possible. I am a doctor myself and, ideologically speaking,
I completely agree with you about freedom: we are fighting for physicians
to be allowed to keep this freedom especially as far as the therapeutic
method and their relationships with their patients that nobody can decide
by resorting to a law are concerned. At the same time, as a doctor, I would
like to ask you some questions; you probably already answered some of them
but I want to be precise. Could you precisely outline the pathologies the
use of your protocol may be appropriate for? Could you show us comparative
data between the results obtained with the application of your method and
those obtained with the application of chemotherapeutic protocols? Do you
have data pertaining the survival rates, the controls and the number of
years after the therapies are administered according to your reference
protocol? These questions are important to us; we can guarantee you
that, as it is our major duty towards the citizens, we will give you as
much support as you need: I am not speaking of trial but of clinical control
and assessment that for us - independently of who we like or dislike -
is a duty towards the citizen.
Giuseppe del Barone - I carefully
listened to Professor Di Bella and I must be frank: when he says
“nobody ever died with my treatment” I immediately think that my friend
Massidda's question is answered. If nobody died then the comparison with
chemotherapy should not be made, as many people died with it.
Thus I would like to be
precise about this aspect because Professor Di Bella spoke a lot about
breast tumours and devastating therapies, about mastectomy and so on.
I would also like Doctor
Giuseppe Di Bella to listen to me so that we will be able to exchange ideas.
Professor Di Bella, my question is specific: you know the situation much
better that I do (I have been a doctor for about forty years). You'll certainly
know about quadrantectomy, statistics concerning recovery after a non-devastating
operation are very wide. Would your method, that we are here to learn,
replace even such operations or improve the quality of life that these
operations can already make good? Basically, when you say that nobody dies,
you are automatically stating that this treatment is in complete contrast
with the improvement of life because if there is no death, such improvement
is almost negligible. On the other hand I am deeply convinced that your
treatment will have even miraculous results especially as regards an improvement
of life; but if we are talking of the fact that no people die, you put
your treatment in complete contrast with past positions that had negative
but also positive results. I would like to tell my great friend Gramazio
to relax: I am a member of the FNOM (National Federation of the Medical
Association) central committee and I can assure you that freedom of prescription
does exist; there can be no doubt about it.
Giuseppe Del Barone - What
I am saying is that one thing is making a private prescription that is
also approved by the patients after properly being informed (and is thus
legitimate), and quite another is speaking of a prescription issued by
the National Health Care System, about which we heard the disquisition
of magistrate Maglie and of all Italy. I will now end my speech: I would
like Professor Di Bella - that I esteem deeply - to tell us whether his
therapy intends to replace traditional treatments or assure an improvement
in the patient's quality of life with this trial, more than with clinical
records, because what we need is a trial carried out by others and not
by ourselves. I believe this is the basic question.
Alessandro Cé - First
of all, the Professor's considerations always start from the assumption
that a doctor practising this profession basically is an honest, ethically
well-balanced person and so on. Diverging information, furthermore, exists.
Although there is talk of the patients' informed approval, it is clear
that if they can test the effectiveness of the therapy, they will never
be able to prefigure the mechanism underneath.
My question then is the
following: don't you think that, in any case, even with the freedom of
treatment and of choice as the fundamental principle, it would be ethically
important to have a body to assess the reliability of the trial under way?
The Federation of the Medical Association certainly showed an unbelievable
malpractice by forcing general practitioners not to prescribe that substance,
which is an incredible and unacceptable thing.
Don't you think, however,
that, from an institutional standpoint, a body delegated to carry out a
similar task should be established? Furthermore, although neglecting the
drugs' economic aspect, as the allocations are to be paid by the National
Health Fund, shouldn't there be a analysis of the financial repercussions
that are a direct consequence of the therapy's suitability? In this case,
should repercussions be seen, it would be possible to insert those products
within the therapies to be carried out by the National Health Care System.
In the light of this important
preamble, I would like to ask you the reasons which hampered the spreading
of information pertaining your trial, especially in the academic circles,
and stirred so much the institutions' hostility.
Finally, I would like to
ask you to be absolutely frank with yourself before than with the others,
and I'd like to know whether there is something in your trial, apart from
the fact that it does not comply with the specific criteria of international
trial, that cannot today be used by other people who can assess the authenticity
and effectiveness of your method.
Antonino Mangiacavallo -
I would immediately like to underline how puzzled I am to tackle this problem:
not so much as a member of the Parliament but as a doctor and as an M.P.,
not just as the scientific implications that this issue entails but also
for the social and journalistic uproar that we saw in the past few days
with the involvement of the mass media, of the magistracy and of a large
part of the public opinion. Thus, I will try to make some considerations
in this short time available, although I will not miss the opportunity
to ask you some specific questions.
First of all, I would like
to start from two things you said, one being that it is necessary to support
the freedom of treatment and the other that when assessing a therapy's
effectiveness, the economical aspect, at least initially, should not be
considered. I firmly believe that the freedom of treatment is a cornerstone
in the respect towards the citizen and I presently see no reason to worry
about the lack of such freedom. I would start to worry if some form of
libertinage or anarchy in prescription should be advanced instead of freedom.
I perfectly agree with you when you say that a therapy's economical evaluation
cannot absolutely be taken into consideration, especially when facing tragic
pathologies as the neoplastic ones. To be honest, however, I must tell
you that I am a little puzzled about some of your scientific statements.
In particular, I am referring to your statement that the goodness of the
therapy you tested could also be assessed by that fact that it never caused
any deaths. This could be considered like any other symptomatic therapy;
I clearly do not intend to underestimate the potentiality of your therapy
that, however, I don't know from the biochemical, electrophysiological
and strictly scientific standpoints.
I get further worried when
I see that patients or citizens can be psychologically influenced in order
to make them carry out a particular kind of therapy that no elements can
help determine whether it is effective or not. In this way illusions would
arise and would make the neoplastic patients' situation even more tragic.
Finally, Mr. Professor,
considering that a clinical trial must not be based on subjective but rather
objective evaluations, I would like to ask you the following question:
were the studies that your team made carried out by double blind versus
placebo or versus other therapies, as laid down by international directives
and by science that many people harshly judged even during yesterday night's
television programme? Did your researchers carry out a clinical follow-up
in a rigorous, precise, scrupulous way and with statistically reliable
data, as my colleague Massidda asked before, or were the evaluations merely
based on a limited and non-selected survey? You claim that it is impossible
to use a standard therapy for all types of existing tumours. I can assure
you, in fact, my medical experience taught me this, that there are patients
suffering from a pancreas or breast carcinoma that are treated only surgically
and who are perfectly healthy even after many decades.
I would like to ask you
another specific question. We have often heard that your group, Professor
Di Bella, is opposing the control of the trial by judicially-authorised
bodies as they would have prejudices against your therapy and your team.
What are the elements that induced you to decide beforehand that the involved
bodies were prejudiced against you? If such elements do exist, I would
like them to be discussed openly.
Finally, excuse my presumption
that is particularly respectful of your experience, competence and academic
past, it is not possible to say that science destroys common sense. I am
afraid that when looking for the truth - and we're all here to do that
- presumption (mine, not the others') sometimes may frustrate science's
breakthroughs.
Annamaria Procacci - I truly
believe that today's hearing, in this institutional seat, can strongly
contribute to re-establish serenity and help us join efforts again, which
is what we all need.
The main protagonist is
always the sick person: I think that none of us can or want to forget it.
I believe it is necessary to hurry up and start the controls, or trials,
as they are called, immediately, according to rules having the highest
objectivity possible. We have always believed that, Mr. Professor, (and
I think I perfectly understood the cultural message your brought us this
morning, as that pertaining the principle of living together with cancer),
the patient and the physician's therapeutic freedom is man's unavoidable
duty. We also believe that doing whatever we can in the field of prevention
is a duty of society, and our own duty too: we have been fighting this
battle for the prevention of cancers by trying to improve the quality and
the style of our life, as well as the air we breath and the food we eat.
We also believe it is necessary
to create a greater opening towards the research of “new” therapeutic methods,
although they actually are not very new. However, in order to dispel the
doubts I as well as other people have, as they were put forward in other
seats, I would like to ask you this question: your protocol, as far as
I know, is the outcome of a mixture of elements, somatostatin being the
main one, obtained through their variable dosage, if I am allowed to use
this non-technical term. So how is it possible to scientifically reconcile
(I am interested in this point as it would allow me to understand which
trial to carry out) this variability of the therapeutic elements with the
reproducibility of the experiment? I think that this is currently one of
our major doubts.
Furthermore, Mr. Professor,
the roads you walked on for your research during your long experience crossed
those of researchers from other countries and I believe that this could
be another interesting point, at least as far as I am concerned.
I would finally like to
ask you to what extent your methods could be used for children affected
by tumoral pathologies.
These are the points that
mostly interest me and I can assure you that we are, as well as everyone
else here, I believe, interested to follow the therapeutic method that
you developed even in its subsequent phases.
Giuseppe Fioroni - First
of all I would like to thank Professor Di Bella for his speech. Mine is
made up by three rapid considerations. At the beginning of his speech,
the Professor underlined the importance of the freedom of treatment, the
freedom for physicians to prescribe a therapeutic method apart from instructions
or diktats. The problem is then the following, I believe: the therapeutic
freedom must fall within the context of precise criteria; I think that
a scientist who has an academic background surely remembers his first university
lessons where he is taught to make sure that the therapeutic freedom with
the administration (testing the products on man and not on guinea-pigs)
does not risk becoming freedom of damage. It is for this reason that I
believe it should be kept in mind that in the past, even in the recent
past (I'm not speaking of your method as I do not know it exhaustively),
whenever the mass media focused their attention on people suffering from
cancers, we have had a long series of the so-called “hope journeys” that
led sufferers, not just terminally-ill patients but also those at the initial
stages of the disease, to follow methods that were allegedly considered
to be, certainly in good faith, useful for some pathologies.
My second question to you
then, which I will ask you with the same humility Mangiacavallo referred
to earlier is this: shouldn't a knowledgeable scientist give the scientific
community, both national and international, data, protocols and other elements
that would be used to go more in depth of and actually achieve results?
Massidda mentioned another
aspect: when speaking of comparative methods, I think that it is important
- and you underlined this several times - that the drug that is administered
with the new method does nor cause any damage (primum non nuocere). In
the second place, however, one must make sure that it also adds something
more with respect to the currently used and tested therapies. In the third
place, when an old therapy is discontinued and a new one started (that
might be particularly aggressive or not be able to solve every single case),
it is necessary to be sure, both professionally and ethically, that the
patients who discontinue a treatment choose a better and not a worse one,
even though they are aware that they are following a hope and that they
are not able to cope with their own problems.
There is another consideration
to be made: I don't think that the costs of the therapy may be a problem
because if we were sure that a new method could cure even just a limited
number of cases, we couldn't certainly avoid the need to spend any figure
to save a life.
There is another problem
concerning a case which I personally experienced and that is connected
to one of the issues that Procacci put forward: the case of a child suffering
from an acute haemopathy, He was in intensive care and his parents decided
to make him follow your method. When a doctor has to decide whether to
continue with the conventional therapy (whose remission, or recovery, rate
was 60% as final datum) or interrupt that treatment and choose another
one without having sure statistical data, do you think that he should also
be held ethically, as well as experimentally, responsible for his professional
capability of freedom?
My last remark concerns
an aspect that I don't think was correctly interpreted by some of my colleagues:
Professor Di Bella clearly said that his method is not toxic, and that
it never caused any patient's death, so that it presumably accompanied
the patients' deaths, if any, by assuring them a better quality of life.
I believe that this is the reliable data; the data that we would like to
get, though, are the recovery rates and the pathologies they refer to.
President -The first round
of questions is over. Professor Di Bella may now please start to answer.
Prof. Luigi Di Bella - Many
questions are fundamentally the same so that they can be given one single
answer.
One of them concerns the
clinical trial and I would like to talk about it briefly as we have here
a great deal of colleagues physicians (Some deputies say: “Too many!”).
I don't think that any of us, when we have to prescribe an antispastic
drug, will ask its clinical trial first. One could object that this drug
was already tested: ok; and if I prescribe drugs that were tested and that
are good in fighting cancer, why should I carry out a trial? The protocol
which I developed is made up by drugs which have already been tested although
their trial did not involve the field of practical medicine. Take retinoic
acid for example: who has ever thought of prescribing it? Yet, rigorous
scientific surveys proved its usefulness. Scientific reports continually
demonstrate this. Why should I start to carry out a clinical trial of retinoic
acid when I already know everything about the compound, I know how to prepare
it, I know its composition, I know all this compound's chemical and physical
properties, I know its toxicity and the way it acts? What should I test
about it? Should I test it to give tens of millions or maybe some billions
to institutes that claim to carry out clinical trials?
What I have just said for
retinoic acid is also true for beta-carotene. Wailer began to talk of the
possibility of transforming beta-carotene into vitamin A already in 1932.
Then we had Coon's research who saw that one molecule of beta-carotene
was necessary to give two molecules of vitamin A. Everything was later
confirmed and today we know that beta-carotene is a provitamin A, we know
its solubility and absorption. What should I test in this case again? Retinoic
acid, beta-carotene; and there are tens of volumes about vitamin E: what
else should I test again?
And let's speak of another
substance, bromocriptine, which I use as well. Who does not know that bromocriptine
is a key element to secrete prolactin and all the things it does for mesencephalic
nuclei? And finally there is somatostatin.
What should be known about
somatostatin is not known. I happened to show, and the experiment actually
was successful, that the stimulation of habenulas' ganglions increases
the number of platelets in the bloodstream: I went from 200 thousand that
are normally in the bloodstream up to 600 thousand. Then within 72 hours,
platelets return to the previous levels. I tested it on man and I know
it is continually done. So, should I test what was already the object of
a huge number of tests and experiments as well as being described in the
literature?
Let's now get to the sore
point: somatostatin is a principle secreted by the diencephalon that can
stop the production of the somatotropic hormone.
We have already known this
for at least fifty years, because researchers had problems in isolating
the somatotropic hormone, but it is made up by a good 91 amino-acids. Carrying
out a synthesis of so large a polypeptide is not an easy thing.
If the methods that were
discovered later hadn't been used, we would not be where we are now. I
know that research is still being carried out, even in America, to prove
that somatostatin affects only the elements of the APUD system, a striking,
nice term: amino-processor-upted-decarbosilation.
So somatostatin's only function
would be limited to the APUD system. But what about its effect on gigantism
or acromegaly? They have been forgotten although we have known these things
for various decades now. We know all the effects when it is in excess and
when it lacks, and we still have to test somatostatin? Why? Because Gebion
suddenly felt like speaking of the APUD system.
The basic problem of this
deduction consists in believing that an injected substance's only function
is the one known by the person using it. The only function that he knows,
he believes, is the substance's action.
The fact that somatostatin
affects the production of the somatotropic hormone rules out the possibility
of having even other effects. But when do we ever use a substance and know
that it acts in only one way? Just read the various handbooks, now more
than one hundred, and maybe give a look at the monographic parts which
have recently been published. But when is a substance used for just one
effect? How many effects does it have? And does its having many effects
mean that I cannot use it? I use it trying to monopolise the effect that
I obtain in that moment of the day in which I must do it, through the combined
action of many substances that can enhance an effect and weaken others
and so on. In other words, I feel that we are trying to engage in fruitless
discussions, pointless discussions and questions which have already been
analysed with an almost molecular, I'd say, precision.
So we have reached a point
in which the objection raised to me is: the problem is not the substance
but the protocol. This fantastic word “protocol” now comes out. I did not
mention the word protocol, I spoke of a four-principle substance, and not
because I wanted to change things but because I wanted to be a little more
specific. Four. Well actually the principles are more than four, but we
can talk of four groups or categories. The reason is the following, and
is strictly physiological at first, then it becomes physical and chemical
and even mathematical and it even involves combinatorial analyses, differential
calculus and so on. I am just briefly mentioning them. The remedies belonging
to this four-principle substance... It is not just retinoic acid or beta-carotene,
or bromocriptine or melatonin, or somatostatin: no, none of them, but them
all together.
If no combined action of
these substances exists then there is no effect, and if there is it would
be limited or delayed. So my use of the four-element substance formula
has a specific reason underneath. I am just briefly mentioning this aspect
because there are doctrinaire limits to be respected here. Our insight
into this field is very deep. What do we still have to test?
Besides retinoic acid, there
are other acids that act similarly, but the retinoic acid has at least
three receptors. But the three receptors are in the nucleus. Having a receptor
in the nucleus means that things are starting to change a little. They
also are three different receptors and we know how they affect the production
of melatonin, too. So what do I have to find out if this is already a scientific
truth? There are incontrovertible data that we all know. It would be as
if, in order to prescribe some bicarbonate, I'd test its effects first
or ask the protocol of its action. I don't think that such a thing might
make much sense. The important thing, on the other hand, is to determine
the protocol, that is the four-principle substance, as the action of one
of them that is not subordinated to that of the other (the action of the
alpharetinoic acid, for example, is not subordinated to the action of beta-carotene
or of bromocriptine) gets enhanced and thus becomes effective.
I would like to give an
example. Yesterday night I was the guest of a television programme and
I tried to speak but I was told that I was not understood (which may happen);
for this reason I will only repeat very few things.
Let's say that I administer
some retinoic acid or just the retinoids and that I get a specific effect;
let's say - second hypothesis - that I also administer some bromocriptine
besides the retinoids. I can administer these two substances together,
or bromocriptine first because the temporal factor may also change the
effect. I can have two methods of action with two substances but if I administer
a third substance I can decide to introduce it at the beginning, in the
middle or at the end.
According to the binomial,
I can have three combinations available and if I have four, I can have
as many for each of them. How do you call this? We call it factorial in
the combinatorial analysis.
If I have four substances
that make up my formula, I may have the action of one by two and two, by
three, six; by four, twenty-four, that is I may have twenty-four methods
of action with just four substances.
Most of the objections raised
to me involved my using a substance, while the real objection that should
be raised and that would more serious should involve the moment in which
it is produced and its combination with other substances.
And this is just the material
part.
But if I take into consideration
the temporal element, my factorial will also be of five or six and so on;
the methods of action that it would be possible to achieve would thus become
almost incalculable.
I won't dwell upon all the
rest...
(to be continued)
