The identification of germline pathogenic/likely pathogenic (P/LP) variants in cancer predisposition genes can guide treatment and management decisions for the individual being tested and potentially at-risk relatives. Prior studies have raised concerns of racial/ethnic disparities in the detection rates of P/LP variants and variants of uncertain significance (VUSs). In 2018, Color Genomics™, a commercial laboratory, made de-identified, aggregate genetic and clinical information from 50,000 individuals who completed testing for 30 cancer predisposition genes publicly available. It is the largest publicly available database of its kind from a single laboratory. An analysis of individuals from this database with a negative personal history of cancer that identify as European (n = 31,920), Hispanic (n = 1700), African (n = 462) or Asian and Pacific Islander (n = 2602), demonstrated that the VUS rate in the hereditary breast and ovarian cancer syndrome and Lynch syndrome genes was higher for all non-European groups as compared to the European group; Hispanic (7.1% vs. 5.8%; p = 0.029), African (12.3% vs. 5.8%; p < 0.001), Asian and Pacific Islander (13.1% vs. 5.8%; p < 0.001). In the other cancer genes (OCGs), the P/LP rate was lower; Hispanic (5.1% vs. 7.6%; p < 0.001), African (2.4% vs. 7.6%; p < 0.001), and Asian and Pacific Islander (4.3% vs. 7.6%; p < 0.001). The VUS rate was also higher in the OCGs; Hispanic (16.2% vs. 12.2%; p < 0.001), African (21.6% vs. 12.2%; p < 0.001), Asian and Pacific Islander (24.4% vs. 12.2%; p < 0.001). Our study emphasizes the reality of disparities in the results of cancer genetic testing and highlights factors that propagate these inequities.

Background The United States Preventive Services Task Force (USPSTF) lists 32 grade A or B recommended preventive services for non-pregnant United States (US) adults, including colorectal cancer screening (CRC). Little guidance is given on how to implement these services with consistency and fidelity in primary care. Given limited patient visit time and competing demands, primary care providers (PCPs) tend to prioritize a small subset of these recommendations. Completion rates of some of these services, including CRC screening, are suboptimal. Expanding delivery of preventive services to other healthcare providers, where possible, can improve access and uptake, particularly in medically underserved areas or populations. Fecal immunochemical testing (FIT) (at-home, stool-based testing) for CRC screening can be distributed and resulted without PCP involvement. Pharmacists have long delivered preventive services (e.g., influenza vaccination) and may be a good option for expanding CRC screening delivery using FIT, but it is not clear how PCPs would perceive this expansion. Methods We used semi-structured interviews with PCPs in North Carolina and Washington state to assess perceptions and recommendations for a potential pharmacy-based FIT distribution program (PharmFIT™). Transcripts were coded and analyzed using a hybrid inductive-deductive content analysis guided by the Consolidated Framework for Implementation Research (CFIR) to elucidate potential multi-level facilitators of and barriers to implementation of PharmFIT™. Results We completed 30 interviews with PCPs in North Carolina (N = 12) and Washington state (N = 18). PCPs in both states were largely accepting of PharmFIT™, with several important considerations. First, PCPs felt that pharmacists should receive appropriate training for identifying patients eligible and due for FIT screening. Second, a clear understanding of responsibility for tracking tests, communication, and, particularly, follow-up of positive test results should be established and followed. Finally, clear electronic workflows should be established for relay of test result information between the pharmacy and the primary care clinic. Conclusion If the conditions are met regarding pharmacist training, follow-up for positive FITs, and transfer of documentation, PCPs are likely to support PharmFIT™ as a way for their patients to obtain and complete CRC screening using FIT.

Routine outpatient visits were converted to telehealth appointments, and nonurgent endoscopic procedures were cancelled, resulting in dramatic declines in colorectal cancer (CRC) screening. Electronic medical records and registries can identify patients not up to date with screening, use of at-home FIT kits mailed directly to patients can be expanded, and positive tests can be followed up with automated calls and text prompts from direct patient messaging platforms—all strategies that have proven effective at increasing screening rates and follow-up.

In a cohort at average risk for colorectal cancer, a cell-free DNA blood-based test had 83% sensitivity for colorectal cancer, 90% specificity for advanced neoplasia, and 13% sensitivity for advanced precancerous lesions.

Introduction Colorectal cancer (CRC) is the second leading cause of cancer deaths in the United States. Surveillance colonoscopy is recommended 1‐year after surgical resection for patients with stage I‐III CRC; however, only 18%–61% of CRC survivors complete this test. This study describes clinician‐identified barriers and facilitators to surveillance colonoscopy among CRC survivors. Methods We conducted semi‐structured interviews with clinicians until thematic saturation was achieved. Interviews were analyzed using the social cognitive theory. Results Thirteen clinicians were interviewed, and all identified health system‐level barriers to surveillance colonoscopy completion; the most common being fragmented care due to patients receiving care across many health systems. Clinicians also identified social determinants of health barriers (e.g., geographical distance between patients and health systems) to 1‐year surveillance colonoscopy completion. Conclusions Clinicians identified several potentially modifiable barriers to 1‐year surveillance colonoscopy completion which, if addressed, could improve post‐treatment care and outcomes among stage I‐III CRC survivors.

Greater than the coronavirus disease 2019 (COVID-19) crisis, systemic inequity in social determinants of health is the pandemic that has long fostered vulnerability to disease and poor health outcomes in the USA. Our response has major implications for the health of our nations.

Background: Mailed fecal immunochemical test (FIT) outreach effectively increases colorectal cancer (CRC) screening but is underutilized. This pilot aimed to determine the use of FIT for CRC screening among Medicare Advantage enrollees when offered via mailed outreach and the factors associated with FIT return. Methods: Our pilot study included Medicare Advantage enrollees who were 50–75-years old, not up to date with CRC screening, and had a billable primary care encounter in the prior 3 years. Eligible patients received a letter containing information about CRC screening and a FIT kit, screening status by FIT was then assessed using the electronic health record. Results: Of the 1142 patients identified, 945 were eligible for outreach. On 12-month follow up, 29% of patients (n = 276) completed CRC screening via FIT, with a median return time of 140 days [interquartile range (IQR) 52–257]; 6% (n = 17) of the completed tests were positive, and 53% (n = 9) of patients have completed a diagnostic colonoscopy. Patients with primary encounter <12 months prior to mailed outreach were most likely to complete a FIT. Over the 12-month study period, CRC screening rates increased by 5% (63–68%). Conclusions: Mailed FIT outreach in a Medicare Advantage population was feasible and led to a 5% increase in CRC screening completion. Our pilot revealed rare incorrect patient addresses and high lab discard rate; both important factors that were addressed prior to larger-scale implementation of a mailed FIT program. Further research is needed to understand the potential impact of multilevel interventions on CRC screening in this healthcare system.

Uptake of colorectal cancer screening remains suboptimal. Mailed fecal immunochemical testing (FIT) offers promise for increasing screening rates, but optimal strategies for implementation have not been well synthesized. In June 2019, the Centers for Disease Control and Prevention convened a meeting of subject mat-ter experts and stakeholders to answer key questions regarding mailed FIT imple-mentation in the United States. Points of agreement included: 1) primers, such as texts, telephone calls, and printed mailings before mailed FIT, appear to contribute to effectiveness; 2) invitation letters should be brief and easy to read, and the signa-tory should be tailored based on setting; 3) instructions for FIT completion should be simple and address challenges that may lead to failed laboratory processing, such as notation of collection date; 4) reminders delivered to initial noncompleters should be used to increase the FIT return rate; 5) data infrastructure should identify eligible patients and track each step in the outreach process, from primer delivery through abnormal FIT follow-up; 6) protocols and procedures such as navigation should be in place to promote colonoscopy after abnormal FIT; 7) a high-quality, 1-sample FIT should be used; 8) sustainability requires a program champion and organizational support for the work, including sufficient funding and external policies (such as qual-ity reporting requirements) to drive commitment to program investment; and 9) the cost effectiveness of mailed FIT has been established. Participants concluded that mailed FIT is an effective and efficient strategy with great potential for increasing colorectal cancer screening in diverse health care settings if more widely imple-mented.
