Moreover, the loss of benign aggregates in deeper sections is considered a prominent indicator of a benign process. 4 To conclude, BMB is required for staging and evaluation of lymphomas and is performed even when the likelihood of involvement is low, as it may portend an inferior clinical outcome and impact therapy selection.Some prognostic factors for neoplastic polyps are listed below: Sex: men twice as likely to have adenomas ( Best Pract Res Clin Gastroenterol 2017;31:419 ) Adenoma detection rate: 24.7% in men and 14.3% in women ( Br J Cancer 2016;115:1421 ) Age: prevalence increases with age.
