Cancer: A Collagen Disease, Secondary to a Nutritional Deficiency?

By W.J. McCormick, MD

SummaryCould a lack of vitamin C be the reason cancer spreads within a body? Nutrition-savvy physician W.J. McCormick thought so, and in this fascinating article from the April 1959 issue of the Archives of Pediatrics, he explains why. McCormick begins by citing the long-known observation that cancer tends to take root mainly in areas of the body that have become depleted in collagen—the elastic connective tissue responsible for “cementing” cells in their place. As collagen diminishes, he says, cancerous cells become free to exercise their natural "amoeboid activity" and move to other parts of the body (i.e., metastasize). Since the body requires vitamin C to produce collagen, Dr. McCormick argues, it stands to reason that a deficiency of the vitamin enables the spread of cancer—a notion supported by the fact that cancer patients tend to be severely depleted in the nutrient. Given the facts, McCormick concludes, the reason for the activity of many carcinogens—including cigarette smoke—may lie in their tendency to destroy the C vitamin.

Cancer: A Collagen Disease, Secondary to a Nutritional Deficiency?

In a previous paper,1 we advanced the hypothesis that the invasive metastasis of cancer was etiologically secondary to a degenerative change in the connective tissues, notably the condensed connective tissue of the “basement membrane” underlining the epithelium of the dermal and mucosal tissues, which in turn could be secondary to a deficiency of vitamin C. This same deficiency could involve the collagenous intercellular cement substance that normally holds the epithelial cells together in orderly arrangement, thus further contributing to faulty healing and metastasis of precancerous lesions. 

Since our first paper on this subject was published, additional evidence contributory to the validity of our hypothesis has come to our attention, which we wish to present.

Gillman et al.,2 in a histopathological study of dermal injuries, report the following: 1) The dermal changes in chronically injured areas seem to represent alterations in either preexisting collagen or elastin, resulting in the formation of “pseudoelastic tissue,” definable by "both morphologic and tinctorial criteria.” 2) This pseudoelastic tissue is regularly encountered in sites of chronic injury to connective tissues in the skin as well as in other structures such as the arteries and gallbladder. 3) This pseudoelastic tissue, preceded by and associated with extensive, though nonmalignant, epidermal invasion of the dermis, can consistently be produced experimentally in normal human subjects with altered connective tissue in injured sites.

In their summary these authors state:

1. “It is shown that similar elastotic degeneration of collagen is invariably present in the dermis in many degenerative skin conditions that may, and frequently do, become precancerous.

2. "It is suggested that the elastotically degenerated dermal collagen may play an important role in the pathogenesis of skin cancer.”

These authors in no way implicated vitamin C status as related to the development of the elastotic degeneration of collagen observed in their experiments, and no determination of the vitamin C status of their subjects was reported.

The observations of Gillman et al. are not altogether new. Bonney,3 in a study of precancerous tissue changes, finds constant loss of connective tissue—usually hyaline changes in the collagen and fraying at the edges of epithelial cells. He states, “In the area of primary carcinoma, there has always occurred a complete disappearance of yellow elastic tissue, and it is in this deelasticized area that the first epithelial down-growths occur.” (Bonney, in 1908, had no knowledge of vitamin C.)

Wolbach, S.B., and Howe, P.R.,4 have observed that the ground substance (collagen), normally effective as an intercellular cement substance [and] capable of holding epithelial cells together in normal relationship, assumes a watery consistency in scurvy. Gersh, I., and Catchpole, H.R.,5 found that the liquefaction of collagen in scurvy is a depolymerization of glycoprotein—the major constituent of the normal ground substance. Pirani, C.L., and Catchpole, H.R.,6 found that the glycoprotein thus liquefied is released into the bloodstream, resulting in an increased serum level of same.

Wolbach, S.B.,7 found that administration of ascorbic acid (vitamin C) in scurvy rapidly restores the normal consistency of collagen. Simpkin, S., et al.8 report that an increase of serum glycoprotein is found in cancer, and other studies by Wingler (1953), Greenspan (1954), Locky et al. (1956), and Lansing (1957) have confirmed this finding. A correlation of these findings gives definite support to our hypothesis. As further evidence, a diagnostic test for cancer has been developed in Germany (The Whitting Reaction) based on the blood protein picture.9

Schneider, E.,10 cites Eickhorn as finding a pronounced deficiency of vitamin C in cancer cases, averaging 4,550 mg by the saturation method, while his noncancerous controls averaged only 1,355 mg. Bodansky et al.11 studied the vitamin C level of blood plasma and white blood cells in healthy subjects as compared with that of cancer cases. They found the levels in the latter to be significantly lower. Russell et al.12 report that recurrent periods of scurvy—interspersed with periods of lettuce supplementation to prevent death—resulted in a significant shortening of the time of appearance of induced cancer in guinea pigs. These findings give further support to the etiologic relationship of vitamin C deficiency in cancer.

In accordance with the above observations, we maintain that the degree of malignancy is determined inversely by the degree of connective-tissue resistance, which in turn is dependent upon the adequacy of vitamin C status.

To illustrate this point, the scirrhus, or hard, cancer of the breast is slow to metastasize and may remain inactive, or “in situ,” for many years, whereas the medullary, or soft, cancer of the breast is extremely invasive. In the former there is predominant connective-tissue stroma, which binds the cells together more effectively, while in the latter the structure is mainly cellular and almost completely lacking in connective-tissue support.

It may be that cancer cells, which are known to assume amoeboid activity, do so because of an inherent propensity that becomes manifest solely because they have lost their connective-tissue anchorage as a direct result of vitamin C deficiency. Furthermore, the efficacy of the Papanicolaou and other diagnostic smear tests may be solely due to this same loosely-bound and easy-shedding property of cancer cells that have thus lost their anchorage. The teeth become loose in scurvy for the same reason—namely the liquefaction of the cementum that normally holds them in their sockets under adequate vitamin C status. 

That the cancer cell per se is not malignant is shown by the fact that even after metastasis to distant parts of the organism, it continues to exercise in degree its normal genetic function. For instance, secondary breast tumors have been found to secrete milk, secondary gastric tumors to secrete hydrochloric acid and pepsin, secondary liver tumors to secrete bile, etc.

The systemic or metabolic nature is shown by the recorded occurrence of multiple primary cancers (3.7 percent of all cases, according to U.S. statistics). In 420 such cases reported by Warren and Gates, 111 had three or more primary lesions, 67 had primary cancer in symmetrical organs, and 242 had primary cancer in different organs. We have recently seen reports of two cases in which five primary cancers were found.

If our hypothesis is valid, it would appear that the term “malignant disease” is a misnomer. Cancer is not a disease that strikes its victims like a bolt of lightning from a clear sky but rather an ailment that we unwittingly cultivate or contract by perverse habits of life. Ravdin, I.S.,13 has said: “While surgery and radiology are helpful, they do not attack the underlying biological defects…Some time, some place the existing jigsaw puzzle will be properly put together, and we shall wonder why the correct answer evaded us for so long a time.”

The therapeutic implications from the above observations suggest that our major effort should be directed toward prevention of the cause of the cellular disarrangement—collagenous breakdown of epithelial and subepithelial tissues—as manifested in open sores or fissures that fail to heal readily and unusual or easily produced hemorrhage, since such lesions may readily become precancerous.

Advance warning of such conditions may be noted in female subjects who bruise easily, as indicated by unaccountable “black and blue” marks. We have found that fully 90 percent of our adult female population are so afflicted, yet little or nothing is done about it though this condition can be readily reversed in a matter of days by a liberal intake of vitamin C from natural sources—supplemented by oral or parenteral ascorbic acid in pronounced cases.

Our observations have led us to the conclusion that the major cause of vitamin C deficiency in our modern civilization may be the well-nigh universal tobacco addiction. The smoking habit not only militates against normal nutritional practice but actually neutralizes or destroys to a great extent what little vitamin C is taken in food.

We have found by clinical and laboratory means (in checking the vitamin C requirements of subjects while smoking and not smoking) that the smoking of one cigarette, as ordinarily inhaled, tends to neutralize in the body about 25 mg of vitamin C, or the content of an average-sized orange. This reciprocal effect is due to the pronounced chemical action of ascorbic acid as a reducing agent.14

Our findings in this respect have been confirmed in general by independent research in the U.S.A. and in Europe. On the basis of our hypothesis, these findings would explain the phenomenal increase in lung cancer in smokers in recent years.

This new theory of the etiological relationship of vitamin C deficiency in cancerogenesis suggests the possibility that all physical and chemical cancerogens may act indirectly by bringing about or exaggerating a latent deficiency of vitamin C. A comparable situation has prevailed regarding alcohol. For many years it was thought that alcohol was the specific cause of peripheral neuritis in the alcoholic subject, but it is now known that deficiency of vitamin B1 is the culpable agent—the alcohol acting indirectly by increasing the body requirement of this vitamin. 

Recently the Sloan Kettering Institute16 reported a series of experimental transplants of live cancer cells in human subjects in an effort to get answers to the following questions:

  • “Why will cancer strike one American in four, and why will the other three not get cancer?

  • What are the differences between the cancer-prone and the cancer-free?

  • Why does a tumor smolder in one human, grow slowly but steadily in another, and flame wildly through the body of a third?

  • Why does a cancer—very rarely but demonstrably—stop growing, melt, and disappear in some patients? Why does cancer growth in other patients seem at times temporarily checked, and why does it then accelerate again?

  • Is there immunity to cancer? If so, is it something that exists in the cancer-free but is lacking—or lost or destroyed—in the cancer victim?

  • Are there at least partial natural defenses against cancer? Can they be identified, studied, stimulated, increased, created artificially, or borrowed to protect the potential cancer victim—or rescue those attacked?”

To begin with they transplanted cancer tissue under the skin of the forearm in 15 advanced cancer cases. In every case the cancer implant “took,” grew vigorously, and spread—for periods ranging from 6 weeks to 6 months—before they were removed by surgery.

Obviously these subjects were completely lacking in resistance to cancer. For comparison another group of 14 willing subjects (inmates of Ohio State Penitentiary), normally healthy and cancer free, were given similar injections of the same stock of cancer cells; in every case there was an overwhelming defense reaction, and within 4 weeks almost all the cancer tissue had been destroyed.

In these studies no cognizance was given to the nutritional background or living habits of the subjects and no correlation in this respect was envisaged. It is our belief that if such an assessment had been made, a better approach to solution of the problem would have been achieved. However, these experiments seem to confirm the concept of a systemic or metabolic etiology in cancer.

It is not expected that our hypothesis, as advanced herein, will lead to a cure for cancer in its advanced or metastatic stages. But the prospects for prophylaxis and the curbing or containing of the disease in its early stages seem most encouraging.

As an aid in the solution of this vital problem, it is suggested that biochemical studies of vitamin C status be made on all middle-aged subjects and nutritional guidance given accordingly—in the hope of at least effecting prophylaxis of this terrible disease. (A simply qualitative color test of the urine is now obtainable for this purpose.) After all, "an ounce of prevention is worth a pound of cure.”

Summary

We submit herewith additional evidence in support of our previously advanced hypothesis1 that deficiency of vitamin C—by bringing about disintegration of epithelial and connective tissue relationships owing to liquefaction of the intercellular cement substance (collagen)—results in a breakdown of orderly cellular arrangement that could be the precursor to metastasis and malignancy. 

The recent observations of Gillman et al. on collagen and connective tissue changes in the dermis of chronically injured areas are cited,2 indicating formation of “pseudoelastic tissue.” They suggest that similar collagenous degeneration is invariably found in the dermis in many degenerative skin conditions that frequently become precancerous and frankly cancerous and that elastotically degenerated dermal collagen may play an important role in the pathogenesis.

These authors in no way implicated vitamin C deficiency in the etiology of these degenerative changes, but we believe that such nutritional deficiency may be the primary cause of precancerous connective-tissue degeneration.

Other authors are cited to show that the increased serum-glycoprotein level in cancer cases—sometimes used as a diagnostic test—could readily be produced by the breakdown of collagen and associated connective tissue, and we believe that it could thus serve as a precursor of metastasis. Thus cancer could be a collagen disease of nutritional etiology.
