Navigating epigenetic epidemiology publications
W Yu et al, BMC Epig Comm, November 22, 2023, (Posted Nov 27, 2023 11AM)

From the abstract: "Since its beginning more than 75 years ago, epigenetics has been an evolving field with growing applications to the study of cancer, aging, and gene expression in response to environmental exposures. The emergence of high-throughput technology for measuring epigenetic markers has enabled population-based studies. The relatively new field of epigenetic epidemiology investigates epigenetic associations from a population perspective for insights into disease risk, prevention, and progression. "

Influence of family history on penetrance of hereditary cancers in a population setting.
Leigh Jackson et al. EClinicalMedicine 2023 11 102159 (Posted Nov 14, 2023 8AM)

From the abstract: "Women with a pathogenic BRCA1 or BRCA2 variant had an increased risk of breast cancer that was higher in those with a first-degree family history (relative hazard 10.3 and 7.8, respectively) than those without (7.2 and 4.7). Penetrance to age 60 was also higher in those with a family history (44.7%, CI 32.2-59.3 and 24.1%, CI 17.5-32.6) versus those without (22.8%, CI 15.9-32.0 and 17.9%, CI 13.8-23.0). A similar pattern was seen in Lynch syndrome: individuals with a pathogenic MLH1, MSH2 or MSH6 variant had an increased risk of colorectal cancer that was significantly higher in those with a family history (relative hazard 35.6, 48.0 and 9.9) "

Combined population genomic screening for three high-risk conditions in Australia: a modelling study
P Lacaze et al, e Clin Medicine, November 2023 (Posted Nov 11, 2023 4PM)

From the abstract: "This modeling study assessed the impact of offering combined genomic screening for hereditary breast and ovarian cancer, Lynch syndrome and familial hypercholesterolaemia to all young adults in Australia, compared with the current practice of clinical criteria-based testing for each condition separately. Our findings suggest that offering combined genomic screening for high-risk conditions to young adults would be cost-effective in the Australian public healthcare system, at currently realistic testing costs.

Targeted gene expression profiling predicts meningioma outcomes and radiotherapy responses.
William C Chen et al. Nat Med 2023 11 (Posted Nov 10, 2023 7AM)

From the abstract: "Using a discovery cohort of 173 meningiomas, we developed a 34-gene expression risk score and performed clinical and analytical validation of this biomarker on independent meningiomas from 12 institutions across 3 continents (N?=?1856), including 103 meningiomas from a prospective clinical trial. The gene expression biomarker improved discrimination of outcomes compared to all other systems tested (N?=?9) in the clinical validation cohort for local recurrence (5-year area under the curve [AUC] 0.81) and overall survival (5-year AUC 0.80).
