The Other Face of Cancer by Dr Manu Kothari and Dr Lopa Mehta
Not Curable, Highly Palliatable
The raison detre of cancer
therapy is that the chief clinical manifestation of
cancer is a mass of cells - a celluloma called a tumour
or a lump. A cancer therapists knowledge begins
with a tumour, and ends with it. By a variety of
measures, the tumour or the lump can be made to
disappear. The whole cycle of detection and destruction
of the lump is repeated on the reappearance of the lump.
It is a sobering thought that cancer therapy is nothing
more than glorified lmpology.
Tumour and
Before
As elaborated
earlier, both the patient and the doctor are blissfully
unaware of all the happenings, till such time as the
tumour dis-eases the owner or is detected by the doctor.
It is all ignorance from the start of cancer up to
the time of detection of the tumour.
Tumour
and After
What, once the
tumour is found and removed? Back to ignorance
again for some inescapable reasons: The incurable
individuality of each cancer and of its owner make
unpredictable, (a) what the cancer will now do to the
patient, and (b) what the treatment will do to the
cancer. Regarding the former, the course may be, like for
the celebrities listed in chapter three, inexorably
downhill, despite all possible measures. Of, as for the
pathologist- author Boyd51 the tumour may not
reappear for a lifetime.
Treatment, in fact, may aggravate the cancer: Even after
considering the most painstaking criteria of operability,
there are women in whom surgery manages to accelerate the
evolution of breast cancer.82 Surgical
intervention may markedly precipitate distant spread, so
that surgical intervention must be excluded as the
first therapeutic step, even in stage I breast
cancer.83 Surgery, the oldest, most
widely employed, and relatively the most innocuous of all
measures, is itself beset with such unpredictable
hazards. What then could one say of radiotherapy and
chemotherapy with their indiscriminate cytotoxic and
marrow devastating84 potential?
Treated, the tumour is out, the cancer is not,
much less the cancerability of normal tissues. Over a
century ago, Billroth85 aphorized that surgery
removes a tumour, but not the patients diathesis
for cancer. Unfortunately it must be admitted that
all cancer surgery is in large measure palliative, given
the occult spread of disease before treatment in a high
percentage of cases.86 The much
celebrated victory over leukemia must content with the
fact that, although by definition the peripheral blood
picture and the bone marrow are normal during
complete remission, 100 million to 1000 million leukemia
cells still remain, making relapse inevitable.45
Whither
Cancer Treatment?Thus, all told,
prior to the detection of and after the detection/
treatment of a tumour, clinicians are still almost
know-nothings.
Glemsers world-wide survey of Man Against Cancer22
only revealed that the realistic title of his book could
have been Man Helpless Against Cancer: Surgery was
declared dispensable, radio- therapy obsolete, and
chemotherapy a farce. As of 1969,22 any talk
of treating cancer was tantamount to Ecclesiastes Vanitas
vanitatum: Nothing is worth doing, no way is
better than another.87 Has real progress
been made?
At the present time, Brooke88
generalized in 1971, cancer treatment appears to
have reached a culmination, a peak beyond which we have
not moved for several decades. But as all the
therapeutic measures against cancer, as of today, are
held dispensable, we are forced to conclude that what
cancer therapy reached was its Peterian150
(cf. Peter Principle) zenith of imperfection
several decades ago, and all that we have
been doing is to move in circles and call it
progress, recent advances and so
on. Such euphemisms may be justified on the geometric
ground that all circular motions are made up of a series
of motions in a straight line, and any straight line
motion implies progress.
Cancer therapy has almost entirely betrayed the
application of lumpolytic logic to the false premise of a
cure. Watts89 has described the peculiar and
perhaps fatal fallacy of modern times: the confusion
of symbol with reality. Such fallacy dominates
cancerology so that what is diagnosed and treated is not
cancer - a disease of the whole organism17
- but merely its most evident manifestation, a lump or an
-oma. The consoling cures obtained are
largely limited to some unusual forms of malignant
disease, such as chorionic epithelioma (gestational
choriocarcinoma) in women,90 being a
function of the nature of the cancer, rather than due to
any ingenuity of the hit-and-miss treatment.
And Yet
Cancer Must be TreatedHowever, the
indispensable role of cancer therapy must be emphasized.
Despite the accepted impotence of all therapies against
autochthonous cancer, one and all measures are useful
when employed to ease a dis-eased cancer patient. A
cancer patient with a blocked gullet or intestinal
obstruction, a mass in the brain, a massive ungainly jaw
from Burkitts tumour, a fungating mass in the
breast, or a large sarcoma of the bone cannot be
subjected to a course on the philosophy of whither cancer
therapy, but must be eased immediately with an
appropriate palliative measure. Cancer will be with
mankind forever, being a part, and progenitor of it.
Cancer therapists will be needed to play their vital
palliative role as long as mankind survives.
With this background, we can now draw some
generalizations on cancer therapy.
- Cancer, a process
characterized by accumulation of newly formed
cells, dis-eases an individual when it forms a
mass or a tumour large enough to obtrude on the
physiology or the psyche of the patient. Equally
, it comes to the stage of diagnosability by the
doctor, only when it is many million cells
strong and quite a few years old. The therapy of
cancer, except for the gestational
choriocarcinoma, is always a palliative measure.
- A cancers
manifestation may be (a) restricted locally as a
lump in the tongue, esophagus, brain or on the
arm, (b)also found regionally as when a tongue
cancer spreads to the lymph nodes in the neck, or
(c) all over the body - systemic
disease - as in blood cancer, lymph node
cancers and some cancers such as melanoma that
have spread all over.
- Cancer present as a
local and / or regional mass is most amenable to
being cut a way by surgery, together usualoy with
a fair margin of healthy tissues. Most cancer so
present themselves and are so treated. Surgery -
conservative, radical or supraradical -- is the
sheet-anchor of cancer therapy. The surgical
removal of malignant tumours is the oldest form
of treatment for this condition, has retained its
leading role in the course of centuries and is
still the treatment of choice in a high
percentage of cases.91
- Systemic or
whole-body cancers, such as blood cancers
(leukemias), Hodgkins disease, other
lymphomas, may be managed by systemic or
whole-body measures such as X-ray therapy and
cell-poisons euphemistically called anticancer
drugs. Cancers starting locally - melanoma,
lining of the uterus, intestine - may spread to
various sites in the body so that the treatment
has to be given as for systemic cancers.
- Some cancers, as of
the breast, thyroid, prostate, respond, albeit
unpredictably and temporarily, 15 to
administration of hormones and / or ablation of
glands secreting hormones.
- In all leading
centres, a combination of therapeutic measures
are usually employed. The advantage of surgery is
a total absence of toxic action on other cells;
its limitation is its limited reach. X-ray
therapy and chemotherapy provide an all-body
reach; their outstanding limitation is the toll
they take of the many cell-populations that
divide faster than many a cancer. The common
result is - the hair falls off, the mouth,
intestine and skin ulcerate, and the patient
becomes pale and defenseless because of
depression of the bone marrow.
- The follow-up
insisted upon by cancer therapists is to watch
for recurrence of the lump ( or the heightened
cell count as in leukemias). The logical sequence
to recurrence is treatment, all over
again. Sigmund Freud had thirty-three operations
for his oral cancer, over a period of sixteen
years.36
- The science of cancer
therapy does not exclude such measures as
analgesics, stronger pain-killers as morphine,
transfusions, dietary supplements and so on so as
to make the patient feel better.
- It may be difficult
to realise that one of the most fruitful measures
in cancer therapy is an attack on the I-worry
tower of the patient - the tower crumbles
against the power of a positive approach.
The victims of this disease, Weil 92
aphorized as far back as 1915, seem to be
in a very high degree "suggestible" and
impressionable and respond nobly to every
therapeutic effort. Issels experience
seems to bear out Weils observation:
In the twenty years of experience with the
so-called incurables, I have seen that reservoirs
of undreamt-of strength and courage can be drawn
upon, even in "terminal" cases by the
adoption of positive attitude.93
Lewin 94 has talked of a physician
needing the ability to manage his own anxiety
against cancer; what kills a patient often
is the everything-is-lost attitude of his
physician which is betrayed in his eyes, words,
tone or even in the way he walks towards the
patients bed.
Cure-rates
in Cancer TherapyWith average
survival not extending beyond three to four years for the
majority of cancers treated by the best hands in the best
centres, it has become imperative to talk of five, ten
year, and twenty year cure rates, albeit at
the level of a group of patients similarly treated for
a supposedly similar disease. In an age when it is
advocated that the patient should be fully apprised of
the gravity of his disease, the severity of the treatment
and the unpredictability of the outcome, it is as well
that the patient is told that his survival is a herd
function ranging from three months to thirty years,
and that his own survival would depend on what place he
occupies, through probability, distribution, on the herd
survival curve.
When it comes to appraising the effectiveness of
treatment, Sutherland95 comments,
one of the difficulties is the striking range in the
natural duration of cancer of the same site in a series
of cases. Sutherland95 gives among many
cancers, the natural duration of cancers (left untreated)
of the tongue and oral cavity in males ranging from three
months to seventy five months, and of the cervix uteri
and female breast, from three months to twelve and a half
years and two months to seventeen and half years
respectively.
The most commonly cited five year survival rate as a
standard of cure is comparative and fallacious assuming
as it must that all the cases if untreated would
have a nil per cent five year survival rate.67
The real cure rate, Park and Lees 67
define, is repre- sented by the difference between the
five year survival rate of all cases following treatment
and the five year survival rate of those same cases had
they been left untreated. In several forms of
cancer, survival for five years after a therapeutic
procedure means little by itself, since a considerable
proportion of untreated patients are known to survive
five years or longer.96 Park and Lees,67
in a detailed, highly critical article entitled,
The absolute curability of cancer of the
breast, and containing numerous graphs and
mathematical calculations, concluded that (a) it could
not be proved that the survival rate of breast cancer,
using as an index the five year survival rate, was in any
way affected by treatment, (b) treatment was quite
ineffective in reducing the mortality from metastatic
spread, and (c) if the treatment was in any
way effective the so- called effectiveness could
not exceed that required to increase the overall five
year survival rate by more than 5% to 10%.
The whole business of five year, ten year and x-year
survival rates is marred by the fallacy of an early or
late countdown.97 Ms. A has a
breast lump, and she does not bother about it for four
years. Then she decides to get it treated, and dies after
two years, to be registered as a case that came late and
therefore, died early. Ms. B has a similar lump, she gets
treated within six months, lives for four years, and is
registered, in contrast to Ms. A, as the case that came
earlier and survived longer. In reality, Ms. A lived with
her cancer for six years, and Ms.B for four and half
years. The apparent longer survival of Ms.B was because
the countdown on her started earlier. An extended
limitation of the above fallacy of the countdown arises
from the fact that no one -neither the patient nor the
doctors - knows exactly when the cancer started in the
body.
A cancer patient, at an individual level, is no
statistic, as he is often made out to be. Carrying within
himself two forms of uniqueness, one his own and the
other that of the cancer he carries, he does not lend
himself to any fruitful predictions or comparisons.
Victory
over Childhood LeukemiaThe current
showpiece 14,22,271 of the cancer world is the
hard- won victory over an otherwise rapidly fatal
leukemia in children, called the acute lymphoblastic
leukemia, usually abbreviated as ALL. Firstly, we may see
the nature of the success and then understand its
mechanism.
Nature of Success 45,98,265-277,315
- Before the
introduction of effective therapy,
the average survival rate was less than three
months: now a small percentage of patients
survive five years and more. The continuing
survival of an ALL patient, under therapy, with
disappearance of leukemia cells from the bone
marrow and blood is generally called
remission , a term applicable to
other forms of leukemia as well.
- Leukemia cells
persist during remission, for the disease rapidly
recurs on discontinuation of therapy: It
has been estimated that before treatment the
cancer patient has about 1012 (1000
billion) or more malignant cells in his body, and
that when he is brought into so-called complete
remission he still has from 109 (one
billion) to 1010 (10 billion)viable
malignant cells.265
- The observed
increases in a verge survival, therefore, reflect
only improved palliation.
- The most important
factor in survival is not the type of leukemia
cells nor their pre-treatment number, but the
response to therapy - a factor that unpredictably
resides in an individual patient and his cancer,
and not in the treatment. Under the same
therapy, boys may fare significantly269
worse than girls.
- The treatment
accorded to ALL cases is no different from
that given in other forms of leukemia, or
cancers. The treatment comprises agents - drugs,
X-rays, - that act as cancer-inducing agents in
the laboratory, and sometimes in humans. The
complications of the therapy of ALL are as varied
and formidable as with other cancers. Despite
remission, patients die-seemingly not of
leukemia, but of infections of the most unusual
nature by micro-organisms that are ordinarily
non-pathogenic, or of sudden hemorrhage.
- Therapy of ALL
produces remission possibly by pushing the
disease, as it were, under the carpet. While the
therapy is busy providing remission by clearing
the bone marrow and blood of leukemia cells,
leukemia cells settle in the brain, spinal cord,
meninges, tests etc., to eventually bring about
the so-called extramedullary (outside the bone
marrow) relapse. Certain drugs 268 probably
assist such transfer of the disease from the bone
marrow to elsewhere.
- ALL therapy is
essentially a titration between killing more
leukemia cells while hoping to kill less of
normal cells.315 No known treatment of
ALL has such selective action.98 Drugs
and X-rays exercise relentless toxicity, and the
leukemia cells commonly turn resistant to the
action of drugs.
- Newer methods 271-275,315
of treating ALL are afoot - varied types of
immunotherapy, and bone marrow transplantation.
The formidable problems posed by transplantation
- a harrowing method of treatment 275
- are nowhere near a solution, and present a
highly nocuous double-edge: The transplantee must
be pre- prepared to accept the transplant by
intensive drugging and irradiation that render
the patient thoroughly defenseless against
infections. Should the grafting succeed, the
guest-marrow-cells show no compunction in setting
loose on the host a vicious graft-
versus-host-reaction / disease, usually
abbreviated as GVHR / GVHD. Transplant means a
cure rate of perhaps 10% 275
and death for many of the remainder.275
- The lay14
and learned 271 exhortations to
subject more and more ALL cases to the aggressive
cure-or-kill therapy rarely amplify the facts98
that the treatment is merely palliative,
increasingly complex, costly in terms of money
and therapeutic complications, fraught with
uncertainty all the time, an emotional gamble for
the patient/ relatives/physician, and that
regardless of the supra-intensive
therapy274 fatality far exceeds
survival.
- In 1957, Burkitt
discovered in African children a cancer, called
Burkitts tumour /lymphoma, and now reported
from all parts of the world.22,266,276
Burkitts contribution was held as something
utterly unique in medical history,22
for it pointed to a viral origin of cancer, an
assumption that could not 15,276 be
proved right. The initially dramatic way in which
Burkitts tumour responded to chemotherapy
led to the hope that this may lead to the
eventual control of acute leukemia (ALL).277
A parallel may be profitably drawn at this
stage between ALL and Burkitts tumour: Both
are essentially made up of lympho-
blasts,98,276 occur
predominantly in children, respond rather
dramatically to drugs combined with X-ray
therapy, and what is most important, both were
and are held as leads towards finding the cause
and cure of cancer. Points (I) through (x) and
the increasing realization that Burkitts
tumour behaves as obstinately 266 as
ALL put a seal on many a hope best quoted of
Burnet:15 To a great many
people, medically trained scientists as well as
laymen, the pot of gold at the end of the rainbow
of medical research is the discovery of the cause
and cure of cancer.
Modus
Operandi of SuccessA word about the
essential mechanism of the success, whatever, against
ALL: A patient with a completely blocked esophagus
because of cancer would die in a few days - not of
cancer, but of starvation, as he would even if the
obstruction were by a stricture or a foreign body.
Treatment does not tackle the cancer, but the obstruction
caused by it, assuring thereby a flow of nutrients, and a
lease on life unhampered by the threat of starvation.
Similarly, what therapy does in ALL is to remove or
minimize in a small percentage of patients, the
obstructions/compression of other normal tissues, in the
bone marrow, brain and elsewhere, to the point of
allowing life to continue, with no change in the basic
pathology. It is important to realize that the same
cellular force that makes leukemia cells continue
multiplying regardless of the therapy also sees to it
that normal cells follow suit to populate vital tissues
of the body so as to allow the patient to survive and be
reckoned as cure or remission.
All told, ALL success is an example of palliation - the
crowning glory of all forms of cancer therapy.
Yes, It
Is Useful to Cure CancerYes,
said the great Metchnikoff,99 it is
useful to prolong human life. And, despite the
blatant iconoclasm of this chapter against cancer
therapy, it can be asserted that it is good to cure
cancer and thus to prolong useful human life. Cure
( L. curatio, from cura meaning care) truly
implies taking care of, and curing cancer means
taking care of a cancer patient, as far as is possible,
as best as is possible, and to the maximal well-being of
the patient. The physician is undoubtedly the most
important intermediary between ones disease and
ones dissolution, and the physicians
benevolence can mean good life until death. Yes, it is
good to cure cancer.
