Post-Bomb Leukemia. Another delayed effect of radiation has already been recognized in humans. Dr. William C. Moloney of Tufts Medical School and Dr. Robert D. Lange report in Blood, The Journal of Hematology on leukemia (blood cancer) among Japanese atom-bomb survivors. Most people near the centers of explosion at Hiroshima and Nagasaki died of heat or blast. Some survived these effects, but got heavy doses of gamma rays and neutrons. In Hiroshima, 750 people who had been within 1,000 meters (3,300 ft.) recovered from their radiation sickness and remained apparently well for years. Then an unusual...
Hope for Middle Incomes. The City of Hope is one of the newest and most active centers for leukemia research. It began 40 years ago as a couple of tents on the edge of the desert for tuberculosis patients from nearby Los Angeles. Now a 75-acre complex of low, rambling buildings in well-landscaped grounds, the hospital community lives up to its name. The beds are reserved for TB, heart and cancer cases, but they must be those to whom medicine and surgery can still offer a prolonged and more comfortable life...
...City of Hope's leukemia unit comprises 32 beds, an outpatient department and scattered laboratories, where its chief, Dr. Howard Richard Bierman, and a team of a dozen assistants carry on treatment and research. New Jersey-born, St. Louis-trained Dr. Bierman is already a veteran (at 39) of investigation into blood cells, and something of a maverick among leukemia specialists...
Hope for Control? For almost a century after Berlin's Dr. Rudolf Virchow named leukemia ("white blood") and de scribed it as a proliferation of the white cells, little more was learned about it. Most researchers have tried to find out where the white cells come from, and why. Dr. Bierman thinks this is only one part of the picture, and probably not the most important, because in some forms of leukemia, it is now known, there is no excess of white cells...
Treatment, Dr. Bierman insists, must take into account not only the apparent overproduction of white cells, but the whole cycle of production, delivery, removal and destruction. White cells normally live only two to four days. But in some leukemia victims, he has found, the cells may live as long as 100 days. This, in what Bierman calls his "balance hypothesis," means principally that removal and destruction are slowing down somewhere. The phenomenon of overproduction of the white cells may often be an illusion (some normal people manufacture many more white cells than leukemics without suffering ill effects...
