RESUMO

BACKGROUND: Individuals with a non-syndromic family history of colorectal cancer are known to have an increased risk. There is an opportunity to prevent early-onset colorectal cancer (age less than 50 years) (EOCRC) in this population. The aim was to explore the proportion of EOCRC that is preventable due to family history of colorectal cancer. METHODS: This was a retrospective multicentre European study of patients with non-hereditary EOCRC. The impact of the European Society of Gastrointestinal Endoscopy (ESGE), U.S. Multi-Society Task Force (USMSTF), and National Comprehensive Cancer Network (NCCN) guidelines on prevention and early diagnosis was compared. Colorectal cancer was defined as potentially preventable if surveillance colonoscopy would have been performed at least 5 years before the age of diagnosis of colorectal cancer, and diagnosed early if colonoscopy was undertaken between 1 and 4 years before the diagnosis. RESULTS: Some 903 patients with EOCRC were included. Criteria for familial colorectal cancer risk in ESGE, USMSTF, and NCCN guidelines were met in 6.3, 9.4, and 30.4 per cent of patients respectively. Based on ESGE, USMSTF, and NCCN guidelines, colorectal cancer could potentially have been prevented in 41, 55, and 30.3 per cent of patients, and diagnosed earlier in 11, 14, and 21.1 per cent respectively. In ESGE guidelines, if surveillance had started 10 years before the youngest relative, there would be a significant increase in prevention (41 versus 55 per cent; P = 0.010). CONCLUSION: ESGE, USMSTF, and NCCN criteria for familial colorectal cancer were met in 6.3, 9.4, and 30.4 per cent of patients with EOCRC respectively. In these patients, early detection and/or prevention could be achieved in 52, 70, and 51.4 per cent respectively. Early and accurate identification of familial colorectal cancer risk and increase in the uptake of early colonoscopy are key to decreasing familial EOCRC.

RESUMO

Colonoscopy is the method of choice for colorectal cancer screening. To be effective, screening colonoscopy must have high quality standards. The key element is the quality of the preparation. However, up to 20% of patients are inadequately prepared and, at present, anterograde washing is the least tolerated part of the procedure. In the choice of preparation, safety is a prerequisite and efficacy is a priority. Tolerance is a secondary but nevertheless influential factor in the quality of preparation and has consequently been the primary focus of many recent studies. In the last few years, a rapidly increasing number of studies have evaluated new drugs, dosages and adjuvant therapies to improve efficacy and tolerability. These studies have collaterally shown that inadequate preparation and lack of adherence to the prescribed regimen can be partially predicted, making it essential to identify this patient subgroup and invest the necessary effort in their instruction. New individualized and flexible approaches are expected for the different clinical scenarios. The search for the ideal colonoscopy preparation, which would be tolerable, safe and above all effective, remains open.

RESUMO

BACKGROUND: Capsule endoscopy has demonstrated its clinical utility in the evaluation of the small bowel, and, accordingly, it has been suggested that it could be useful for the identification of small-intestinal polyps in patients with polyposis syndromes. The objective was to establish the effectiveness of wireless capsule endoscopy for detecting small-bowel polyps in patients with hereditary GI polyposis syndromes in comparison with barium contrast series. METHODS: Consecutive patients with GI polyposis syndromes were included. Small-bowel follow-through series and capsule endoscopy were performed within 1 week, in a blind fashion. The number and the location of polyps were analyzed. RESULTS: Twenty-four patients with familial adenomatous polyposis (n = 20) or Peutz-Jeghers syndrome (n = 4) were included. Capsule endoscopy detected small-bowel polyps in 7 of 24 patients (29%), whereas a barium contrast study identified small-intestinal polyps in only 3 of these 7 patients. In the 4 remaining patients, all of them with familial adenomatous polyposis, polyps detected by the capsule but missed in radiographic series were located at either ileum (2 patients), jejunum (1), or duodenum (1). No procedure-related complication was observed in any patient. CONCLUSIONS: Wireless capsule endoscopy is a highly accurate technique for the detection of small-bowel polyps in patients with hereditary GI polyposis syndromes, and it represents a valuable alternative to barium contrast series in the surveillance of patients with Peutz-Jeghers syndrome.
