Excerpt from New York Medical Journal, Vol. 106: August 25, 1917 Rontgen rays and clinical and laboratory findings; 2, latent cancer which is usually advanced without any typical symptoms and can be diagnosed by the Rontgen. Ray readily; and 3, cases in which there is very little doubt about the diagnosis from a clinical standpoint. In early carcinoma the symptoms are obscure and there are usually few gastric symp toms. As a rule there is no obstruction, the acidity may be unchanged, there is no lactic acid, and there may be no blood in the gastric contents or stools. There is insufficient data to justify an exploratory operation. This class of cases must be examined very carefully by the Rontgen rays, and very often repeated exminations are necessary if the diagnosis is to be made in time to be of real value to patient and surgeon. In latent cancer the disease is far advanced with only one or more symptoms, and can usually be diagnosed by the rontgen rays. Often these cases are referred with the history of partial pyloric obstruction, and as there are no other symptoms, we are greatly surprised when the Rontgen examination reveals an advanced carci noma which is inoperable. A question frequently asked is: How early can gastric carcinoma be diagnosed by the Rontgen rays, or how early does gastric carcinoma reveal rontgen ological signs sufficient to justify an exploratory operation? Carman, who has had a large expe rience at the Mayo Clinic, answers this question as follows: Admitting that the only cure for cancer is early operation, early diagnosis is a matter of prime importance. Admitting also that there are no definite clinical findings in early cancer. The statement is warranted that next to the exploring finger of a trained surgeon. Rontgen rays will re veal more cancers in the early stages than any other diagnostic means. Iience. Every patient of cancer age with indefinite gastric symptoms should be sub jected to a Rontgen examination. But how earlv can cancer of the stomach be detected? That de pends upon, 1, the character of the cancer whether a frank tumor, an insidious infiltration, or a can cerous ulcer: 7 its situation; 3. The examiner's familiarity with the work. And. _t. The amount of rontgenological evidence. Together with the extent of clinical corroboration. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
