Further supplementary memorandum submitted
by BREAST UK and Crawley Cancer Contact
1. 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 of, for instance:
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;
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 that 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
in which participants were randomised without being told, a procedure
that would have been illegal elsewhere (for instance in Denmark).
We guess 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 already have a copy.
2. COMPLEMENTARY
MEDICINE
Cancer patients often find much solace and comfort
from complementary therapies that 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 the therapies were provided
routinely as part of 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. There is also a place
for some alternative treatments, perhaps when all else has failed,
provided that clinical responsibility is taken by an NHS oncologist,
and some members of this committee have already signed the EDM
on Integrated Cancer Care tabled by Nicholas Winterton. Again,
research methodologies for such interventions need to be both
imaginative and appropriate, and urgently need funding.
3. 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 connection 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. We know that breast cancer
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 interest of the pharmaceutical
industry to sponsor research into prevention, except when there
is a notion that a drug might show promise. It is pharmaceutical
companies that make the agro-chemicals as well as the anti-cancer
drugs: they are not interested in seeing a decline in the incidence
of cancer. So research into aetiology and strategies for prevention
must be funded independently, and 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.
