However, the application of LR relies on a maximum likelihood approach, which may not yield optimal combination rules for maximizing sensitivity at a clinically desirable specificity and vice versa. In this article, we have developed an improved regression framework, sensitivity maximization at a given specificity (SMAGS), for binary classification that finds the linear decision rule, yielding the maximum sensitivity for a given specificity or the maximum specificity for a given sensitivity. We additionally expand the framework for feature selection that satisfies sensitivity and specificity maximizations. We compare our SMAGS method with normal LR using two synthetic datasets and reported data for colorectal cancer from the 2018 CancerSEEK study. In the colorectal cancer CancerSEEK dataset, we report 14% improvement in sensitivity at 98.5% specificity (0.31 vs. 0.57; P value <0.05). The SMAGS method provides an alternative to LR for modeling combination rules for biomarkers and early detection applications.

In 2020-2021, we conducted a pre-post quasi-experimental pilot implementation study of a tailored and comprehensive LCS program in two Choctaw Nation of Oklahoma (CNO) primary care clinics in rural Oklahoma. The program included screening quality assessment, academic detailing, practice facilitation, health system enhancements, technology support, centralized LCS coordination, and community outreach. Eligibility for LCS was based on the 2013 US Preventive Services Task Force guidelines. Participants completed pre- and post-intervention surveys on their knowledge, attitudes, and experiences regarding LCS. All participant charts were extracted to determine LCS completion. Post-implementation semi-structured interviews of patients and clinicians were conducted and practice facilitator notes were analyzed. Participants (N=57) averaged 67 years, and 66% were current smokers. The proportion of participants who were up to date with LCS increased from 39% to 58% (p<0.01). About 18% of patients reported improvement in general care choice and treatment discussions with their doctor and about 40% reported an improvement in their awareness or understanding of lung cancer and receipt of LCS. We also identified several key facilitators and barriers to LCS implementation at the practice and health system levels. LCS acceptance and uptake improved significantly in this community-engaged pilot intervention which informed a subsequent cluster-randomized trial. Comprehensive and community-engaged LCS programs may have the potential to improve the delivery of LCS in underserved community settings.</p>","PeriodicalId":72514,"journal":{"name":"Cancer prevention research (Philadelphia, Pa.)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143525217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Women with a family history of breast and ovarian cancer but without pathogenic germline variants in recognized breast cancer risk genes are recommended annual breast imaging if their predicted 10-year breast cancer risk is 5% or higher, using the Breast and Ovarian Analysis of Disease Incidence and Carrier Estimation Algorithm (BOADICEA) breast cancer risk model, as outlined in the current GC-HBOC guideline. However, women who initially do not meet this risk threshold may do so later, even if there is no new cancer in their family. To determine when this threshold is crossed, one could annually repeat BOADICEA calculations using an aging pedigree: the \"prediction by aging pedigree\" (AP) approach. Alternatively, we propose a simplified and more practical \"'conditional probability\" (CP) approach, which calculates future risks based on the initial BOADICEA assessment. Using data from 6,661 women registered with GC-HBOC, both methods were compared. Initially, 74% of women, ages 30 to 48 years, had a 10-year breast cancer risk below 5%, but 53% exceeded this threshold at an older age based on the AP approach. Among the women with an initial risk below the threshold, the CP approach revealed that 99% of women exceeded the 5% threshold at the same or an earlier age compared with the AP approach (88% of cases were within the same year or 1 year earlier).

No prospective human study has yet explored the role of necroptosis in colorectal cancer development. We conducted quantitative analysis of biomarkers for necroptosis [transient receptor potential cation channel subfamily M member 7 (TRPM7) and phosphorylated mixed lineage kinase domain-like protein], inflammation [cyclooxygenase-2 (COX-2)], apoptosis [BCL2-associated X (BAX) and terminal deoxynucleotidyl transferase dUTP nick end labeling], and cell proliferation (Ki67). This was done using tissue microarray biospecimens from the Cooperative Human Tissue Network and rectal biopsies from a longitudinal study within the Personalized Prevention of Colorectal Cancer Trial. In the human colorectal adenoma-carcinoma sequence, we observed an inverse expression trend between BAX and TRPM7; TRPM7 decreased from normal mucosa to small and large adenomas but significantly increased in early colorectal cancer stages (Ptrend = 0.004). It maintained high levels through all cancer stages. An increased COX-2 intensity in the epithelium was noted during tumorigenesis (Ptrend = 0.02) and was significantly associated with an elevated risk of metachronous polyps (odds ratio = 3.04; 95% confidence interval, 1.07-8.61; Ptrend = 0.02). The combined composite index scores of TRPM7 and COX-2 were strongly linked to 6- to 47-fold increased risks for metachronous adenoma/serrated polyps, whereas combined scores of phosphorylated mixed lineage kinase domain-like protein or TRPM7 with BAX were associated with an 11.5- or 13.3-fold elevated risk for metachronous serrated polyps. In conclusion, our findings suggest that COX-2 expression within normal-looking colorectal mucosa is significantly associated with an increased risk of metachronous colorectal polyp. Furthermore, our results propose the hypothesis that synergistic interactions among necroptosis, inflammation, and apoptosis could play a pivotal role in human colorectal tumorigenesis.

Accelerated aging, where BA exceeds chronologic age, has been studied in relation to cancer development, but its utility in cancer prevention remains unclear. Accelerated aging holds promise as a tool to explain the increase in early-onset colorectal cancer (EOCRC). We investigate the association of accelerated aging and the presence of preneoplastic polyps (PNP) in the colon, defined as tubular adenomas and sessile serrated adenomas. In this study of persons under age 50 undergoing colonoscopy, we used peripheral blood samples to determine BA and age acceleration metrics. Age acceleration was determined by interrogating DNA methylation at specific CpG sites across the genome, which has been shown to correlate with age. We then conducted logistic regression analyses to evaluate the association between age acceleration and PNPs. In total, 51 patient samples were evaluated. We found that that the odds of harboring a PNP are 16% higher with 1 year of accelerated aging, as measured by GrimAge. However, the strongest risk factor for PNPs remained male sex. This represents one of the first studies to explore accelerated aging and PNP in patients under the age of 50. A risk-stratified approach to EOCRC screening would minimize unnecessary colonoscopies and minimize healthcare burden while addressing the increase in EOCRC.
