title: Who are we missing and why?
abstract: The concept of "missing" is defined as failure to diagnose cancer before it has spread beyond the organ of origin. Data are presented for the 11 sites at which cancer occurs most frequently in the United States. There is a clear association between the survival of patients with cancer of a particular site and the percentage of cancers of that site diagnosed in a localized stage. However, the reasons for variation in the proportion of cases discovered while localized, which varies from 79% for uterine corpus to 12% for pancreas, appear to be varied and complex. Available data suggest that the nature of the tumor-host relationship and metastatic potential of the neoplasm are probably more important than alertness on the part of the patient and the physician, and probably have a more profound influence on stage of disease at diagnosis than currently available screening techniques.
