Study information

Primary study designInterventional
Study designInterventional randomised controlled trial
Secondary study designRandomised controlled trial
Scientific title
Study acronymSCORE 3 (Screening COloREctal)
Study objectivesComparisons of attendance, detection rates and acceptability of total colonoscopy, flexible sigmoidoscopy and fecal occult blood test (FOBT) as primary screening tests for colorectal cancer.
Ethics approval(s)Piedmont region ethics board, date of approval: 17/06/2002 (ref: 8151/28.3)
Health condition(s) or problem(s) studiedColorectal cancer, colorectal polyps
InterventionPatients, after informed consent, were individually randomized from rosters of GPs or from residents in specific districts or city neighborhoods, either to total colonoscopy or flexible sigmoidoscopy or FOBT.

1. Colonoscopy: oral bowel preparation with sodium phosphate solution (two litres). Mild dietary restrictions (i.e. to increase the uptake of water and to reduce consumption of foods rich in fibers the day before the test) recommended. Colonoscopy performed by gastroenterologists in hospital endoscopy units. No standard protocol for sedation. If the baseline colonoscopy could not be completed to the cecum, the patients were referred for a Double Contrast Barium Enema (DCBE), whenever advanced adenomas (see Polyp classification) were detected in the segments examined. DCBE was not routinely indicated in the case of a negative incomplete colonoscopy, due to patient's intolerance.

2. Sigmoidoscopy: bowel preparation was limited to a single enema (133 ml of 22% sodium phosphate) self-administered at home two hours before the test. No dietary restriction recommended. Screening undertaken by gastroenterologists in hospital endoscopy units. Aim of the examination: to advance the endoscope beyond the sigmoid-descending colon junction under adequate bowel preparation. Polyps smaller than 10 mm detected during the flexible sigmoidoscopy were removed immediately and sent for histological assessment. Subjects with polyps larger than or equal to 10 mm, as well as those detected with advanced adenomas (see polyp classification) referred for total colonoscopy. Subjects with suspected colorectal cancer or with polyps too large to be removed endoscopically referred for surgery.

3. FOBT: immunochemical test performed on a single sample without any dietary restriction. All cards stored at 4°C and shipped weekly to one central laboratory (Laboratorio di Citopatologia, CSPO - Florence). Patients with positive test called by the study staff and they are offered an appointment date for a total colonoscopy.
