Journal ArticleDOI

Cancer risks by gene, age, and gender in 6350 carriers of pathogenic mismatch repair variants: findings from the Prospective Lynch Syndrome Database

Mev Dominguez-Valentin, +94 more
- 01 Jan 2020 - 
TL;DR: Management guidelines for Lynch syndrome may require revision in light of these different gene and gender-specific risks and the good prognosis for the most commonly associated cancers.
Journal ArticleDOI

Lack of association between screening interval and cancer stage in Lynch syndrome may be accounted for by over-diagnosis; a prospective Lynch syndrome database report.

Toni T. Seppälä, +62 more
TL;DR: The CRC stage and interval since last colonoscopy were not correlated, which is in conflict with the accelerated adenoma-carcinoma paradigm, and raises the possibility that some CRCs in path_MMR carriers may spontaneously disappear.
Journal ArticleDOI

Survival by colon cancer stage and screening interval in Lynch syndrome: a prospective Lynch syndrome database report

TL;DR: In path_MLH1 and path_MSH2 carriers, more advanced colon cancer stage was associated with poorer survival, whereas time since previous colonoscopy was not, and these results may be in conflict with the view that follow-up of path_MMR variant carriers with Colonoscopy intervals of less than 3 years provides significant benefit.
Journal ArticleDOI

Risk-reducing hysterectomy and bilateral salpingo-oophorectomy in female heterozygotes of pathogenic mismatch repair variants: a Prospective Lynch Syndrome Database report

Mev Dominguez-Valentin, +96 more
- 01 Apr 2021 - 
TL;DR: Findings may aid decision making for women with LS who are considering RRS and little benefit is gained by performing RRS before 40 years of age and premenopausal BSO in path_MSH6 and path_PMS2 heterozygotes has no measurable benefit for mortality.
Journal ArticleDOI

Complications of cold versus hot snare polypectomy of 10-20 mm polyps: A retrospective cohort study.

TL;DR: Cold snare polypectomy is safe and efficacious for removing polyps <10 mm with reduced rates of delayed postpolypectomy bleeding and postpolypectsomy syndrome; however, further evidence is required to establish its safety.
