Examination of Witness (Questions 563
- 564)
WEDNESDAY 21 JUNE 2000
MRS HEATHER
GOODARE
Chairman
563. I now call Mrs Heather Goodare from Crawley
Cancer Contact and Breast UK.
(Mrs Goodare) Thank you very much indeed.
Good afternoon. I have already sent in quite a lot of written
evidence on behalf of both Breast UK and Crawley Cancer Contact.
I do not want to repeat myself but I want just to highlight three
important issues which I think are prominent. The first is informed
consent. Since we made the first written submission from Breast
UK there have been several national scandals with regard to lack
of consent for research procedures. In our local community too
we have had experience for instance of a trial of three months
versus six months chemotherapy for breast cancer patients for
which a protocol was not submitted to the Research Ethics Committee.
Also a trial of drug treatment for ovarian cancer for which REC
approval had been gained but at least one patient had not been
given either an information sheet or a consent form to sign. You
may conclude that these are small hiccups of the kind which may
occur in the local situation where things are not always as they
should be. However, the principle of informed consent has not
been fully acknowledged by even the most prestigious medical journals.
Earlier this month the BMJ published a trial, not a cancer trial,
in which participants were randomised without being told, a procedure
which would have been illegal elsewhere. My guess is that these
examples are the tip of the iceberg. It was to forestall practices
such as these that Breast UK and CERES drew up the guidelines
for ethical research with patients of which you have already had
a copy. The second thing I should like to highlight is complementary
medicine, which has been mentioned by other witnesses. Cancer
patients often find much solace and comfort from complementary
therapies, which appear to be of great benefit in helping them
through their orthodox cancer treatments, both raising immune
function and making them more relaxed. In Crawley Cancer Contact
we offer such therapies on one afternoon a week and the work is
done on a voluntary basis by qualified practitioners. We are carrying
out an audit of our work and so far the feedback we have had from
patients has been entirely positive. We feel that much more could
be achieved if therapies were provided routinely as part of an
integrated hospital or GP care. But managers will not purchase
such treatments unless there is sound evidence for their efficacy.
However, RCTs rarely offer appropriate methodology for such studies,
which need to be qualitative, imaginative, should have patient
defined outcomes, and urgently need funding. The third topic I
should like to highlight is that of causes and prevention. It
is good news that cancer mortality is coming down but we must
find out why incidence is going up, particularly in the hormonally
modulated cancers, breast, prostate and testis. We should find
out whether or not there is a connection between exogenous hormones,
particularly oestrogen mimicking chemicals, and breast cancer.
Is there a link between increased use of agro-chemicals, hormonal
growth promoters, antibiotics and so on and the increased incidence
of cancer generally? We need to look at other environmental factors.
In Crawley, near Gatwick airport, we have a relatively high incidence
of breast cancer among women under 40[28].
We know that it is particularly common among air hostesses and
we need to know why. We also need to know why the age of puberty
is going down so fast in the UK, since this too is likely to impact
on the development of hormonal cancers. It is not in the interests
of the pharmaceutical industry to sponsor research into prevention
except where there is a notion that a drug might show promise.
Pharmaceutical companies make the agro-chemicals as well as the
anti-cancer drugs. They are not interested in seeing a decline
in the incidence of cancer. Research into etiology and strategies
for prevention must be funded independently. This means a great
deal more Government sponsorship of research. In the end this
will be cost effective. Cancer prevention must make better sense
than expensive palliative treatments in the last few months of
life.
Chairman: Thank you very much for a very clear
presentation of your evidence.
Dr Gibson
564. Would you like to hazard a guess about
how much cancer is caused by environmental effects? People in
the States quote that 80 per cent of cancers are caused by environmental
onslaughts. Do you say that is true?
(Mrs Goodare) I would not say that at all. No, I just
think it is part of the picture. I do not know much about other
cancers than breast, but in breast cancer there is a fistful of
factors, early menarche, late menopause, late childbearing, HRT,
oral contraceptives. All I am saying is that we need research
to see whether or not the environment does impact. Certainly in
Crawley, we are very near Gatwick Airport, there is a lot of pollution,
and we have a lot of air hostesses, who seem to get a lot of breast
cancer.
Chairman: Thank you very much indeed for giving
us your evidence so clearly.
28 This apparent anomaly is probably attributable to
the unusual age distribution of the population in Crawley. Back
