CANCER ITS CAUSE AND TREATMENT

LECTURE I CANCER AS A MEDICAL OR SURGICAL DISEASE

In my lectures given here two years ago I considered, as far as I could in the time allowed, the nature of cancer, and the evidence in favor of its being a medical rather than a purely surgical disease; and in order that the trend of what shall follow may be clearly understood, brief reference may be made to some of the principal points studied and developed in the preceding lectures. To this end I may restate the conclusions presented at their close, as developed in the lectures, perhaps with some alterations or additions which two years' further study, observation, and treatment of cancer may suggest.

It is quite impossible and unnecessary to elaborate again the facts upon which these conclusions are based, which were given very fully in my previous lectures and book; but we may briefly consider some of the features just presented, and some of the evidence why cancer should be considered from a medical rather than a surgical standpoint. For it must be conceded that both the general medical profession and the laity still regard the disease as belonging to surgery, and look only to the knife for any hope in its treatment. In spite of all that has been done the present outlook for the checking of its rising mortality by this means, and for the prevention of cancer, is bad indeed, as will be shown in a later lecture.

But, gentlemen, many great surgeons, in past and present time, as quoted in my former lectures, have acknowledged verbally and in writing their inability to cope with cancer as a disease, and have recognized time and again that they operated only because they knew of nothing better to do. Often it is acknowledged that the operation is only palliative, in the hope, alas, how often futile, that some good might result from it, in the chance that the dread disease would not return. We shall see later, when we come to study the mortality of cancer in various locations, and an analysis of surgical statistics, how slight the foundation is for such hopes.

Both in the past and present times many surgeons of eminence, well acquainted with the disease, whom I quoted in my former lectures, have also more or less casually expressed the conviction that there was some deep-seated constitutional cause of cancer which baffled recognition, but which must have to do with the diet or mode of living of those afflicted. The most recent of these is Dr. William J. Mayo, who has spoken in no uncertain terms along this line, in a recent address as President of the American Surgical Association. And yet how relatively little intelligent effort has been put forth to discover and amend these conditions, and to remove the bodily derangement which eventuates in the formation of the foci of disease which later become malignant and form what is called cancer, or to modify the blood changes which ultimately destroy life!

We may now consider some general matters bearing on the question of a medical rather than an exclusively surgical aspect of cancer.

But it does show that broad medical thought has long recognized that cancer is not a purely local disease, but that it arises from some disturbance of nutrition, tending to localize in some particular spot, even as a neuralgia will occur in some special nerve and be reached, not by local measures, but by those of a general nature. Repeated casual observations have often been made by clinicians, and even by surgeons of prominence, of the apparent relations between cancer and gout or rheumatism, and also diabetes, and all recognize the rebelliousness of cancer when it occurs in connection with obesity. The late Dr. John B. Murphy was very strong in regard to this latter point. The constant occurrence of cancer in rheumatic individuals is a very striking feature, which I observe almost daily.

It is worthy of remark that cancer begins to appear at a wholesale rate at the age when metabolism begins to slow up, and some time after the body growth has become fully established. At this period people are apt to lose the balance between physical effort and the intake of food, eating as much as ever, perhaps more, while becoming more sedentary. At the same time the emunctories become less active. The various affections of metabolism now tend to appear and are associated with imperfect oxidation, or diminished tolerance toward certain ingesta. It is interesting to note that in a study of many thousand cases of eczema I found the disease to be actually more frequent, in proportion to those living, between the ages of 50 and 55 than at any other period of life after the infantile period, or the first five years of life; just about the same time when cancer is most common. And the constitutional conditions at the bottom of eczema are very much the same as those in cancer.

Patients with a cancer just beginning will often, or even generally, seem to be in excellent health. It is indeed remarkable to observe how commonly patients with beginning breast cancer will seem to be in a splendid condition of health. They are ruddy and blooming in appearance, and when the lump is first discovered it is hard indeed to believe that if the erroneous life processes which caused the cancerous lesion to develop are not checked, the patient will before long succumb to the direful disease. Williams remarks that "such types are indications of hypernutrition."

But a most careful study of these patients in every particular will so constantly reveal such errors of life and derangements of metabolism that these must be looked upon as contributing causes, at least, to the development of the local condition which later becomes malignant; in the same way as the patient will appear to be in blooming health just before an attack of acute gout. For when these conditions are rectified by proper dietary and medicinal measures the local cancerous condition not only ceases to develop but actually disappears without surgical removal, as I have repeatedly shown you. These errors and derangements are not commonly evident on a superficial examination, and often are recognized only after very painstaking search, and re-search.

We have not yet arrived at such a clear knowledge of metabolism as to understand just where the fault lies in these cases of seeming perfect health, with the beginning of a neoplasm which may eventuate so disastrously. But we do know that what passes for good health is often fictitious, and is quite compatible with even grave disorders of various kinds. It is more than possible that the apparent well-being of the patient with beginning cancer, which is often observed to be associated with uricacidemia, points also to the correctness of our thesis in regard to its internal causation. As remarked in one of my former lectures, quoting Ribert, "no one has ever seen the beginning of mammary cancer" and no one will ever see the beginnings of cancer of internal organs.

But, whatever may be thought of Haig's theories or statements regarding uric acid, there is no question but that many maladies of many kinds have their origin in the concatenation of processes which has long been recognized clinically as lithemia. Personally I believe that sooner or later it will be generally recognized that the starting point of cancer occurs in some cell or cells, previously normal, probably as the result of local irritation, in which there is a deposit of some of the elements of faulty nitrogenous partition, induced by undue ingestion of animal protein: and that the malignant, reproductive process in the cells is kept up by a continuance of the same supply of imperfectly disintegrated nitrogenous matter.

The condition of the urine furnishes a most invaluable indicator and guide as to the systemic derangements and their correction. This has not reference to the presence of sugar, albumin, or casts, but rather to other features, reflecting the manner in which metabolism is performed. This subject was gone into pretty thoroughly in my former lectures, but must be briefly considered here, because of the great importance of the subject.

It is well known that, while the products of the digestion and disassimilation of carbohydrates and fats pass off by the lungs, generally without harm, those of protein and salts are eliminated by the kidneys, and may be the cause of various systemic derangements. The urine, therefore, when most carefully analyzed volumetrically, exhibits in the clearest possible manner how the metabolism is carried on and where the error lies.

From a study of hundreds of complete volumetric analyses of urine in dozens of cancer patients, both in the very early and late stages of the disease, I have found that this excretion almost invariably exhibits departures from normal which are significant.

First to be mentioned is the relation of the total solids excreted daily to the body weight of the individual; for it is evident that a person weighing 200 pounds should pass off more than a smaller person. The following table represents fairly well the total solids that should pass daily in order to maintain a healthy equilibrium:

These figures do not represent much active exercise, and with increased bodily exertion the solids passed should be more. Men excrete about one-tenth more than women; there are also less urinary solids passed with advancing age, and about five per cent may be deducted for each ten years after forty.

The actual acidity of the urine, as measured by the oxalic acid and phenolphthalein test, is also of the greatest importance. This is not difficult of application and is daily used in my laboratory; the litmus paper test is of relatively little value in comparison with an actual chemical measurement. Thus, with an average standard of 300 we not infrequently find an acidity of 500 or 600, or even 1000 or more, or it may sink to 200 or 100, or even be strongly alkaline. In cancer I have striven, by diet and remedies, to keep it a little below normal, as it has been shown that the blood in this disease exhibits a constantly increasing tendency to diminished alkalescence, or, wrongly called, increased acidity.

But further and very careful volumetrical urinary analysis is very important to determine and maintain the metabolism in its proper condition. Time does not permit such an elaboration of this subject as might be desired, and I can only call your attention briefly to some of the points brought out in my former lectures.

Many observers have found the nitrogenous disintegration very imperfect in cancer cases, and oxyproteic acids are increased and even that in very early cancer. An increase of amino-acid nitrogen was found by Reid in practically every case studied. Others have found an increase in colloid nitrogen, to more than double the normal amount, and also increased elimination of xanthin and urinary ammonia; so that all observers testify to a disturbed nitrogen partition in cancer. The elimination of urea is certainly greatly diminished, even in early stages and when on a full diet, as I have almost invariably observed.

The sulphur partition is also found to be imperfect, in new and old cancer cases, and even a great increase in the urinary discharge of sulphates is constantly noticed in my analyses. Associated with these errors in the nitrogenous and sulphur element is the very common and persistent increase of indican, showing stasis in the small intestine, with bacterial putrefaction.

Imperfect intestinal elimination is constantly observed in cancer cases, both habitually and in the very early, formative period, and also later, even before any recourse to morphin, which, of course, heightens the trouble. In recording the statements of these patients I have been so struck with the almost invariable history of constipation before the first appearance or suspicion of the cancer that I cannot help feeling very strongly the possibility that the toxins produced by the millions of micro?rganisms, generated through intestinal stasis and fecal putrefaction, play a great part in the production of that blood dyscrasia which culminates in the formation of the malignant new growth.

I mentioned to you last year that in hundreds of tests of the saliva in cancer patients the reaction was found to be acid almost invariably, until corrected by dietary and other treatment. I have this test made and recorded daily, half an hour before meals and half an hour after meals, on my cancer patients in the New York Skin and Cancer Hospital. I have also the urine volumetrically analyzed each week, and the results all tabulated in columns on the history sheet, so that the changes may be compared weekly, in regard to each constituent, as treatment progresses. The same is done with the weekly studies on the blood, which I hope to present in full before long.

I think, gentlemen, that from what I have said you can see that the medical aspects of cancer loom up pretty large, and yet we are only beginning to study the disease along these lines. We see, thus, that cancer is not primarily a surgical affection, and that the mere ablation of an offending portion of the body which has become diseased can never preclude a new portion from becoming affected, or prevent a recurrence in the same location; indeed, this often seems to be stimulated and increased by the trauma and by the deranged lymphatic and vascular circulation caused by the operation and the dissemination of actively growing cancer cells through these channels. This will appear more fully later when we come to study the increasing mortality of cancer during these later years of active surgery, and when we come to analyze the actual reports of operative procedures.

I hope, gentlemen, that by these lectures I may succeed in satisfying your minds that if anything is to be done towards staying the steadily rising frequency and increasing mortality of cancer, it must be by carefully wrought out medical means, and not by the knife.

LECTURE II INFLUENCE OF SEX, AGE, OCCUPATION, RACE, CLIMATE, AND FOOD ON CANCER

While cancer is no respecter of persons, and affects all, rich and poor, old and young, male and female, there are some interesting features regarding the disease as it occurs under various conditions which are worthy of consideration.

We have seen in the former lecture that cancer is not a definite something, from without, that attacks the human frame, but that it is only a faulty development and action of certain body cells, which were once normal, with a steady decline in bodily health which tends to a fatal issue in a very large proportion of those once affected with the disease.

We have seen that the cancer patient, both in the very earliest stages and during the whole period of the disease, gives evidence of departures from the ideal normal life, and presents functional disorders of various organs, with derangements of metabolism; these point to errors of nutrition, which latter are of significance in connection with the development and continuance of the malignant disease. The conclusion offered was that cancer is a medical affection, due to systemic causes, and that the simple surgical excision of a certain diseased portion cannot be expected to check or remove such a malady, or to prevent recurrence. And this has been abundantly demonstrated by the history of the disease, with its steadily increasing mortality under increasingly active surgical treatment during the last fifteen years, as was shown in my former lectures and will be further illustrated later.

Recognizing, then, that cancer is a great and widespread disorder of nutrition, let us consider some of the facts regarding its extension and some of the influences concerned in its production.

The death rate in males, however, seems to be increasing of late years; in the United States in 1912 males formed 39.7 per cent; in 1913, 40.1 per cent; and in 1914, 40.6 per cent. In England, according to Williams, the proportion of males to females is increasing much more rapidly. This greater mortality of males is due to the greater number of deaths from cancer of the stomach and liver, buccal cavity, and skin. In 1914 there were 19,889 deaths from cancer of the stomach and liver, or 37.9 per cent of the whole number; of these 10,122 were in males to 9,767 in females, or an excess of 355 males, whereas in 1912 the females were 87 in excess. In the United States the cancer death rate for males has increased since 1901 31.8 per cent and for females 25.3 per cent.

AGE.--Carcinoma is exceedingly rare under 20 years of age, most malignant tumors at that period being sarcomata. After 25 the number of deaths from cancer about doubles each five years up to 40, and then increases steadily, until the actually greatest number of deaths, 6,909 , occurred between 60 and 64 years of age, after which they decreased steadily; there were 267 deaths at 90 and over, 8 of them being 100 years and over. At no period did the deaths of males exceed that of females, and from 35 to 39 years of age the latter were almost three times that of males.

OCCUPATION.--Many attempts have been made to trace the influence of occupation upon the incidence of cancer, but thus far very little of practical interest has been demonstrated; the difficulties concerning this investigation are immense, owing to absence of essential and accurate data. There have been many lists presented, but few of which agree as to details, and all need to be corrected as to the proportion of those living at different ages. There is also the question as to the effect of local or general agencies; thus, as to the result of local injuries on the skin, and also in regard to other agencies, whatever they may be, which produce internal cancer; for tables of occupation do not generally refer to sex, age, or location of the disease.

First, to dismiss the question as to the direct result of local injuries in inducing cancer of the skin, which, at the most, caused only 3.7 per cent of all cancer deaths in 1914, we may cite a few instances in which this appears to be pretty well established.

The occurrence of epithelioma as a direct result of repeated and protracted exposure to X-ray is familiar to all, and is particularly interesting because it occurs commonly among younger persons, and at a time of life when epithelioma is rare; and especially also because the X-ray is constantly effective in curing epithelioma. The rarity of epithelioma resulting from X-ray, considering the enormous amount of exposure which must have occurred in making and using X-ray tubes, implies, however, that there must be some other cause also at work. It has been urged, therefore, that the skin tissue being altered and weakened from repeated and protracted exposure to X-rays, more readily falls prey to some of the chemical or other irritating agencies which have been observed to be followed by epithelioma.

Time does not permit even a mention of the various elements, which are many, that have been credited as excitants of cutaneous epithelioma; but brief allusion may be made to one which formerly attracted much attention, mainly in England; this refers to chimney-sweeps cancer, the mortality from which was at one time at least 5 times greater than that from cancer in males generally, at the same age. This is now, however, of relatively infrequent occurrence, owing to the adoption of other methods of cleaning chimneys. The epithelioma, which more commonly developed on the scrotum, was believed to be due to the long continued irritation caused by the constant presence of soot on the part; other products of combustion and tar derivations have also been accredited with the same result.

The question of the influence of occupation along other lines is really more interesting, because more obscure; but a careful study of available data tends to show the correctness of the thesis on which my former lectures and these are based. This, as you know, is that our so-called advancing civilization, with all its errors of life, in many directions, is at the bottom of the steady increase in the mortality from cancer.
