Organization of Clinical Trial on National Scale: Management of Early Cancer of the Breast

From a study of the organization of a national clinical trial on the management of early cancer of the breast in women there appear to be overwhelming advantages in studying large numbers of patients. To this end centres abroad have been encouraged to join. All the evidence at present suggests that it is feasible to organize a study on this scale, that the documentation and follow-up are accurate, and that the enthusiasm of the participants can be successfully fostered and maintained.
