EFFECT OF STIMULATION OF THE LYMPHOCYTES ON THE RATE OF GROWTH OF SPONTANEOUS TUMORS IN MICE

Abstract
Spontaneous cancers were removed from a series of mice by operation. The animals were then subjected to an exposure to dry heat at a temperature ranging from 55–63°C. for 5 minutes. Immediately afterwards a graft of the original tumor was returned. The mice so treated exhibited a marked increase in their resistance to the growth of the cancer graft, over 59 per cent remaining entirely free from a return of the cancer. In a control series in which no treatment was given 96 per cent of the animals showed a return of the cancer.
