Survival is lengthened by strengthen the collagen function of cellular adhesion, thereby slowing down the invasion and spread of the cancer cells.  Colon cancer spreads mainly vegetatively unlike for example small cell lung cancer with early and aggressive metastasis.  Thus colon cancer was a good choice for their clinical trial.  The uncompromised immune system is also important.  If they added large dose (2 gm/day) of aspirin the results would like be even better.  A third adjunct would be hormone replacement therapy, and the most important would be to starve the cancer with fasting and ketogenic diet, since cancer metabolize glucose in a very inefficient anaerobic process which produces 1/15^th of the ATP that occurs in aerobic metabolism using the citric acid cycle.  There are journal articles supporting all of these assertions.   Thank you pharma for putting profits before people—the dictates of capitalism.

Probably all malignant tumors liberate an enzyme, hyaluronidase, that causes the glycosaminogycans to be cut into smaller molecules, thus weakening the intercellular cement… another enzyme, collagenase, that causes the collagen fibrils to be split into small molecules.  Cameron and Douglas Torman, on the basis of some chemical arguments [in 1970]. Suggested that an increased concentration of vitamin C in the body would stimulate the normal cells to produce increased amounts of the substance hyaluronidase inhibitor…… Linus Pauling point out that it is known that vitamin C is required for the synthesis of collagen[1]…Pauling suggested that an intake of 10 grams of vitamin C per day be given to the patients with advanced cancer. “ For most improvement becomes apparent between the 5^th to 10^th day, which may be very transient, or it may be for weeks or months, and in a few patients prolonged and accompanied by such evidence of objective benefit to included permanent regress has been induced,” p. xi-xii. 

 Carcinoma is a malignant tumor that arises from the cells of any covering membrane.  Because such covering surfaces are the first to be exposed to carcinogenic influences, carcinomas account for more than 90% of all malignancies. 

Adenocarcinoma indicates that the tumor has arisen from some glandular structure and has retained some semblance of glandular formation. 

Sarcoma are tumors of the supporting tissues, such as bone, cartilage, muscle,  fibrous tissue, joint surfaces and fat.  They comprise less than 5% of all malignancies.  P. 20

Basal cell, squamous –cell epithelioma, malignant melanoma

And even in the best of hands, the success rate is only about one in five.  One patient might receive some benefit, while the other four have been rendered thoroughly miserable. To no advantage.  And even the one success is usually comparatively short lived, frequently no more than a matter of months in the usual solid cancers… p. 68.

In 9154 and 1959 Dr. W. J. McCormick, a Canadian physician... recognized that the generalized stromal changes of scurvy (changes in the nature of the tissues) are identical with the local stromal changes observed in the immediate vicinity of invading neoplastic cells, and surmised that the nutrient (vitamin C) that is known to be capable of preventing such generalized changes in scurvy might have similar effects in cancer.    The evidence that cancer patients are almost invariable depleted of ascorbate lent support to this view.  P. 101.

Thus a goat the sized of a man (weighing 70 kilograms, 154 pounds) synthesizes 13,000 mg of this vitamin each day.  For other species—mouse, rat, cat dog, cow, squirrel, and even the house fly—the amount synthesized is 2,000 to 20,000 mg per day). The only resemble explanation of the fact that the smaller amounts would lead to poorer health.
