The laboratory study of the blood from 22 of the cancer patients in the New York Skin and Cancer Hospital under my care, has been instructive as well as valuable along certain lines. In most of them it was made weekly, and often over long periods of time, and the results tabulated for easy comparison, in order to study closely the condition of the patient and the effect of remedies. No very startling revelations were made by these blood studies, they confirmed in the main the observations of others, though some interesting facts were learned from an analysis of the data. They referred to ten cases of cancer of the breast, four of the stomach, two of the uterus, one of the rectum, one of general abdominal carcinosis, and the rest in scattered locations.
The lowest hemoglobin index was 35, with 2,800,000 red blood cells, in a woman aged 59 with cancer of the stomach. The next lowest hemoglobin index was 45, with which the patient, aged 53, died, with inoperable cancer of the right breast; the blood count showed 3,700,000 erythrocytes, and 10,400 white blood cells, 76 per cent of which were polynuclear. During the course of observation, covering several months, the red blood cells were once 2,100,000, but under careful treatment rose to 4,110,000 not long before death. The next lowest red cell count observed was 2,200,000, with 12,000 white blood cells, and 65 hemoglobin index, in a man aged 52, with a terrible inoperative cancer of the cheek and neck, of which he died.
The highest red cell count made was 5,400,000, in a case of cancer of the uterus, in a patient aged 52, the count being 4,064,000 on entering the hospital. The highest hemoglobin index was 90 in a number of severe cases, and 100 in one case of sarcoma, to be detailed in the next lecture. In one recurrent case of cancer of the left breast, which was very distressing at first, the patient died peaceably and without pain, with a hemoglobin index of 90, and 4,900,000 red cells, and 7,400 white cells, of which 75 per cent were polynuclears, 17 per cent small lymphocytes, and 7 per cent mononuclears. Her hemoglobin had been 70 per cent on entering the hospital with 3,360,000 red cells. The highest leukocyte count observed was 18,600 in a case of inoperable cancer of the right breast, not long before death, in an unmarried female of 53; but in the course of treatment it had fallen to 6,200, about normal, from 10,520 before beginning treatment.
