Gastrointestinal Malignancies Colorectal cancer would be the most typical gastrointestinal malignancy in PJS sufferers. The risk of developing colorectal cancer is reported to be as high as 39 and increases with age . Screening protocols for GI cancers incorporate regular endoscopy and/or video capsule endoscopy for any appropriate visualization of the small intestine. In addition, CT or MR enterography can be used as alternative screening modalities [30,31]. In addition, the fluoroscopic GI series can be performed in patients who cannot or usually do not want endoscopy (Figure 7). Capsule endoscopy is additional sensitive inside the detection of polyps than little bowel fluoroscopic research . Nevertheless, this strategy underestimates the number of polyps. At the very least 20 or more extra polyps have been identified on the enteroscopy when in comparison to the capsule endoscopy alone . A baseline screening with upper endoscopy and colonoscopy need to be performed at 8 years of age. If polyps are present,Cancers 2021, 13,9 ofthen sufferers must be routinely screened with repeat endoscopy each and every two to 3 years. When the initial screening reveals no polyps, then endoscopic screening can resume in the age of 18 and repeat each and every two to 3 years (Tables 1 and 2) [12,34].Figure 7.

The threat of developing pancreatic cancer is reported to be as high.
