title: Changing site distribution patterns of colorectal cancer at Thomas Jefferson University Hospital.
abstract: Analyzed data from an earlier reported experience with colorectal cancer at Thomas Jefferson University Hospital, compared with findings observed and analyzed from 1959 to 1977 indicate a changing pattern of distribution of colorectal cancers. These changes lead to therapeutic conclusion that fiberoptic flexible sigmoidoscopy is the preferred diagnostic tool.
