“…Thus, in general, the impact of compliance on cost-effectiveness is becoming an increasingly important issue. A survey of patients aged 50 and older in New York [57] found that less than a quarter reported that their physician had ever discussed colorectal cancer screening. However, about two-thirds reported receiving stool occult blood cards, and 30 of 84 had undergone an endoscopic screening examination.…”

ssssssssssssssssssssssssss s DDW Report ssssssssssssssssssssssssss s Virtual ColonoscopyAdditional prospective studies of the sensitivity and specificity of virtual colonoscopy (VC) have been reported, all of which involve radiologists blinded to the results of conventional colonoscopy (CC). The results were quite mixed. A British group reported that in 201 consecutive patients, VC detected polyps in seven of 14 patients (50 %) with polyps ≥ 1 cm, and in only four of 25 patients (16 %) whose largest polyps were 6 -9 mm [1]. A Japanese group [2] evaluated the sensitivity of VC for right colonic polyps in 58 patients. Five of six polyps > 10 mm (83 %) were detected, but only four of eight (50 %) in the 5 -9 mm range, and there were two flat adenomas and both were missed. A Boston group (Beth Israel Deaconess) studied 100 patients; the sensitivity for polyps ≥ 10 mm was 90 %, and 65 % in the 6 -9 mm range, and at 0 and 24 hours patients reported similar scores for pain and discomfort [3]. The largest study yet performed comparing VC with CC was reported by the Veterans' Association Medical Center in San Francisco [4]. Three hundred patients (291 men, 96 asymptomatic) were studied, of whom 118 had no polyps found by CC. Of these, 33 of 118 had a false-positive finding of polyp on VC. In 182 patients with polyps on CC, VC detected eight of eight cancers (100 %), 90 % of 82 polyps > 1 cm, 80 % of 141 polyps 5 -10 mm, and 59 % of 301 polyps < 5 mm [5].The Mayo Clinic reported an initial experience in tagging stool with barium. In an unblinded study, patients required six or seven doses of 225 ml of dilute barium sulfate over 48 hours to label their stool adequately and detect polyps. The tolerance of this was not reported [6].Overall, the results for virtual colonoscopy continue to be quite mixed, ranging from inadequate to very good. The sensitivity for polyp detection in the 6 -9 mm range is of

The positive predictive value of FOBT on DRE for detecting neoplasia is similar to that of SPS in asymptomatic outpatients undergoing colorectal cancer screening. Positive FOBT on DRE warrants colonoscopic evaluation. Hemoccult testing by DRE may be performed in the office to increase patient compliance with colorectal cancer screening. A negative FOBT on DRE should be followed up with FOBT of SPS.
