title: Introductory statement on the progress of The National Large Bowel Cancer Project: its goals, objectives, and programs.
abstract: The introductory lecture updates the state of the art bearing on cancer of the large bowel. Topics discussed include etiological factors, the pathology of the disease, the role of animal models, the early diagnosis of the disease, including biochemical markers, with emphasis on immunology, and finally therapy, including surgery, radiotherapy, chemotherapy, and the immunological approaches to therapy as identified in the ongoing activities of the National Large Bowel Cancer Project. Interesting aspects of complementing the traditional ways of treating colorectal disease are noted in the discussion of new approaches to chemotherapeutic treatment based on rational developments obtained throught the study of cell kinetics and cell turnover. It is pointed out that this and other interrelationships considered in the multidisciplinary experimental and clinical approaches provide important leads toward the understanding of the mechanisms of disease, discovery of causes and means of prevention, methods of earlier diagnosis, improved rational modalities of treatment, and, one hopes, more successful management.
