Colorectal cancer detection in a Community Hospital Screening Program
J. E. Kurnick, L. B. Walley, H. H. Jacob and L. Nakayama
In its first 4 1/2 years of operation in the Long Beach Community Hospital
Cancer Detection Center, among the 5,595 persons examined, 16 cases of
colorectal cancer were discovered. Fourteen of the 16 had symptoms
referable to neoplasms. Eight had lesions found on proctosigmoidoscopic
examination. Nine had positive findings for occult blood in stool samples,
a 7.5% cancer detection rate among the 120 with positive stool sample
findings. Six patients with cancer submitted one to four stool specimens
that showed negative findings on occult blood testing, and one patient
submitted no specimen. Although valuable in screening, stool testing for
occult blood will not detect all colonic neoplasms. The complaints of pain,
altered bowel habits, or tenesmus warrant sigmoidoscopic examination,
barium enema studies, or both, whether findings in stool samples are
positive or negative.
