In recent years, a great deal more of the energies and moneys of scientists and institutions interested in cancer have been focusing on leukemia in its variegated forms. This intensified search-for-understanding is undertaken with far-ranging vision. Researchers seek beyond control and cure of human leukemia, searching out paths that will provide insight into other forms of human malignancy. This symposium held in December 1966, under the auspices of the Leukemia Society of America, reflects the intensive pursuit of oncologic knowledge that occupies many scientific disciplines.
The symposium opens with a discussion of epidemiological considerations of the leukemia problem. Five papers on various aspects of viral investigation follow. Dutcher initiates the viral section with a chronological review of viral-induced malignancies and concludes with a discussion of problems faced by those trying to show that human leukemia is a viral disease.
