Traditional roles in a non-traditional setting: genetic counseling in precision oncology

Stakeholders Perceptions of Barriers to Precision Medicine Adoption in the United States

Despite evidence that precision medicine (PM) results in improved patient care, the broad adoption and implementation has been challenging across the United States (US). To better understand the perceived barriers associated with PM adoption, a quantitative survey was conducted across five stakeholders including medical oncologists, surgeons, lab directors, payers, and patients. The results of the survey reveal that stakeholders are often not aligned on the perceived challenges with PM awareness, education and reimbursement, with there being stark contrast in viewpoints particularly between clinicians, payers, and patients. The output of this study aims to help raise the awareness that misalignment on the challenges to PM adoption is contributing to broader lack of implementation that ultimately impacts patients. With better understanding of stakeholder viewpoints, we can help alleviate the challenges by focusing on multi-disciplinary education and awareness to ultimately improve patient outcomes.

COVID-19 and the adaptive evolution of genetic counseling

Emerging diseases such as the Coronavirus Disease (COVID-19) have exposed severe weaknesses in the United States and global health. Healthcare systems have struggled and are still severely challenged and strained by this pandemic. It is clear that additional resources are needed to support healthcare providers in managing this and future pandemics. Genetic counselors can play an important supporting role in this fragile ecosystem because their comprehensive and broad training makes them uniquely qualified to meet many of the challenges that arise when healthcare workers and patients are faced with novel diseases. This paper describes the recent involvement of a telegenetic counseling company (Metis Genetics) in communicating and explaining COVID-19 serum antibody results to patients and physicians. This experience demonstrates how genetic counselors may be called upon to play a vital supporting role in the management of infectious disease pandemics. From May 2020 to July 2020, our genetic counseling telegenetics team was asked to provide support to more than 1,580 patients who underwent serum COVID-19 antibody testing and to educate their healthcare providers on the performance properties of this new test. The genetic counselors were able to utilize their expertise to convey test results, information on Center for Disease Control and Prevention (CDC) recommendations, COVID-19 fact-based evidence, to provide psychological support and reassurance to patients, and to respond to providers questions about the test. This experience suggests that the genetic counselors' skillset that has allowed the profession to continuously evolve can also be used in the management of pandemics by communicating directly with the public, supporting other healthcare workers, and assisting individual patients and families navigate the many medical and psychological issues caused by such events.

Analysis of the reported use of practice-based competencies by North American genetic counselors during the COVID-19 pandemic

Genetic counseling services changed due to the COVID-19 pandemic. Many genetic counselors (GCs) moved from in-person to telehealth services. Others were redeployed by choice or necessity, using their expertise to provide COVID-19 care and education. For some, their employment status changed due to budgetary constraints or decreasing referrals. This study surveyed North American GCs to assess the relative use of genetic counseling Practice-Based Competencies (PBCs) as a proxy for the skills used during the first wave of the pandemic, whether GCs were in their current role or in new or adjusted roles. A secondary aim was to determine whether GCs believe their training should be refocused in view of the workforce shifts posed by the pandemic. The survey comprised closed- and open-ended questions and was completed in full by 97 respondents. The study population was representative of the general genetic counseling workforce in terms of gender, race/ethnicity, age, and practice area when compared to the National Society of Genetic Counselors 2020 Professional Status Survey. Most participants (97.9%) indicated that the COVID-19 pandemic resulted in a change to their work, and 89.7% used at least one PBC at a different frequency than before the pandemic. The most significant change was the adaptation of genetic counseling skills for varied service delivery models: 83.5% of respondents indicated that their roles and responsibilities moved to a remote setting and/or utilized telehealth. The majority of participants felt competent using the PBCs during the pandemic. Major themes that emerged from the qualitative data were as follows: (a) adaptation of service delivery, (b) translation of genetic counseling skills, and (c) provision of psychosocial support. This study highlights practice changes for GCs due to the COVID-19 pandemic as well as the increased use of, and need for focused training in, varied service delivery models.

Identification and Confirmation of Potentially Actionable Germline Mutations in Tumor-Only Genomic Sequencing

PURPOSE

Tumor-only genomic profiling (TGP) is increasingly advocated for all patients with cancer given the possible therapeutic implications. It is critical to develop clinical algorithms to identify and address potentially actionable germline findings identified by TGP.

METHODS

A multidisciplinary team analyzed publicly available data for genes in which mutations are implicated in germline cancer susceptibility and established a pipeline to automate clinical referral for evaluation of TGP findings.

RESULTS

A total of 2,308 patients underwent TGP, with 81 patients (3.5%) identified by the automatic referral pipeline; 37 patients (1.6%) were referred outside the pipeline based on concerns by the molecular geneticist, pathologist, or oncologist regarding genotype-phenotype correlation. Thirty-one patients (38%) and 17 patients (46%) underwent germline testing from the automatic pipeline and other referrals, respectively, and of these patients, 23 (72%) and four (24%) had confirmed germline pathogenic variants (GPVs), respectively. The majority of confirmed GPVs were in automatic referral genes, with BRCA2 being most common (confirmed GPVs in 11 [85%] of 13 patients tested), followed by PALB2 (five [67%] of six patients), BRCA1 (two [40%] of five patients), MSH6 (two of three patients), and MLH1 (two of two patients). Forty-eight percent of confirmed GPVs were found in tumors known to be associated with germline mutations in the gene. Germline testing was not performed in 50 (62%) of 81 patients identified by automatic referral as a result of poor patient health or death (30%), lack of follow-up (30%), and patient refusal (30%).

CONCLUSION

Of patients undergoing TGP, 5% had somatic findings triggering referral, and implementation of an automatic referral pipeline based solely on gene versus other clinical or molecular features resulted in a 74% germline confirmation. However, only 41% of referred patients underwent germline testing. Systems-based approaches are needed to identify carriers of actionable germline cancer susceptibility mutations identified by TGP.

An examination of the factors contributing to the expansion of subspecialty genetic counseling

In recent years, genetic counselors have moved into increasingly varied areas of patient care. Yet limited information is known about how these genetic counselors transitioned from more general clinical practice to subspecialized practice. This study was designed to answer three research questions: (1) What common factors establish a need for a genetic counselor in a subspecialty setting? (2) How do genetic counselors in subspecialties establish their positions? (3) Once established, how do the positions of these genetic counselors evolve as the subspecialty expands? Phone interviews with subspecialized genetic counselors led to the development of an online survey distributed through the National Society of Genetic Counselors ListServ. Sixty-eight of the 144 initial participants met eligibility criteria for participation as subspecialty genetic counselors in a clinical role. Physician interest in hiring a genetic counselor, clinical need, genetic counselor interest in subspecialty area, and available genetic testing were commonly reported as contributing factors to position creation. Most subspecialty genetic counseling positions were created as new positions, rather than evolved from a previous position. Over time, subspecialty positions drew more departmental funding and included increased clinical coordination or administrative responsibilities. The results of this study can encourage genetic counselors to collaborate with their medical institutions to utilize their skill-set in diverse areas of patient care.

A Commentary on Opportunities for the Genetic Counseling Profession through Genomic Variant Interpretation: Reflections from an Ex-Lab Rat

The genetic counseling profession continues to expand and respond to the changing landscape of genomic medicine. "Non-traditional" genetic counseling roles have become more commonplace and the transferability of the genetic counselor skill set has been widely acknowledged, particularly in genetic laboratory settings. As these expanding roles continue to mature, all genetic counselors can benefit by learning and adopting clinically relevant skills, such as genomic variant interpretation, which can be applied to direct patient care. These skills can enrich our patients' understanding of their test results, help ensure quality patient care, and could be useful in positioning genetic counselors as critical members in the medical team as we continue to fully transition into the genomic medicine era.

Physician Experiences and Understanding of Genomic Sequencing in Oncology

The amount of information produced by genomic sequencing is vast, technically complicated, and can be difficult to interpret. Appropriately tailoring genomic information for non-geneticists is an essential next step in the clinical use of genomic sequencing. To initiate development of a framework for genomic results communication, we conducted eighteen qualitative interviews with oncologists who had referred adult cancer patients to a matched tumor-normal tissue genomic sequencing study. In our qualitative analysis, we found varied levels of clinician knowledge relating to sequencing technology, the scope of the tumor genomic sequencing study, and incidental germline findings. Clinicians expressed a perceived need for more genetics education. Additionally, they had a variety of suggestions for improving results reports and possible resources to aid in results interpretation. Most clinicians felt genetic counselors were needed when incidental germline findings were identified. Our research suggests that more consistent genetics education is imperative in ensuring the proper utilization of genomic sequencing in cancer care. Clinician suggestions for results interpretation resources and results report modifications could be used to improve communication. Clinicians' perceived need to involve genetic counselors when incidental germline findings were found suggests genetic specialists could play a critical role in ensuring patients receive appropriate follow-up.

Ethical considerations of neuro-oncology trial design in the era of precision medicine

The field of oncology is currently undergoing a paradigm shift. Advances in the understanding of tumor biology and in tumor sequencing technology have contributed to the shift towards precision medicine, the therapeutic framework of targeting the individual oncogenic changes each tumor harbors. The success of precision medicine therapies, such as targeted kinase inhibitors and immunotherapies, in other cancers have motivated studies in brain cancers. The high specificity and cost of these therapies also encourage a shift in clinical trial design away from randomized control trials towards smaller, more exclusive early phase clinical trials. While these new trials advance the clinical application of increasingly precise and individualized therapies, their design brings ethical challenges . We review the pertinent ethical considerations for clinical trials of precision medicine in neuro-oncology and discuss methods to protect patients in this new era of trial design.

"A rising tide lifts all boats": establishing a multidisciplinary genomic tumor board for breast cancer patients with advanced disease

Background

Research suggests that multidisciplinary genomic tumor boards (MGTB) can inform cancer patient care, though little is known about factors influencing how MGTBs interpret genomic test results, make recommendations, and perceive the utility of this approach. This study’s objective was to observe, describe, and assess the establishment of the Breast Multidisciplinary Genomic Tumor Board, the first MGTB focused on interpreting genomic test results for breast cancer patients with advanced disease.

Methods

We conducted a qualitative case study involving participant observation at monthly MGTB meetings from October 2013 through November 2014 and interviews with 12 MGTB members. We analyzed social dynamics and interactions within the MGTB regarding interpretation of genomic findings and participants’ views on effectiveness of the MGTB in using genomics to inform patient care.

Results

Twenty-two physicians, physician-scientists, basic scientists, bioethicists, and allied care professionals comprised the MGTB. The MGTB reviewed FoundationOne™ results for 40 metastatic breast cancer patients. Based on findings, the board mostly recommended referring patients to clinical trials (34) and medical genetics (15), and Food and Drug Administration-approved (FDA) breast cancer therapies (13). Though multidisciplinary, recommendations were driven by medical oncologists. Interviewees described providing more precise care recommendations and professional development as advantages and the limited actionability of genomic test results as a challenge for the MGTB.

Conclusions

Findings suggest both feasibility and desirability of pooling professional expertise in genomically-guided breast cancer care and challenges to institutionalizing a Breast MGTB, specifically in promoting interdisciplinary contributions and managing limited actionability of genomic test results for patients with advanced disease.

Clinical Sequencing Exploratory Research Consortium: Accelerating Evidence-Based Practice of Genomic Medicine

Despite rapid technical progress and demonstrable effectiveness for some types of diagnosis and therapy, much remains to be learned about clinical genome and exome sequencing (CGES) and its role within the practice of medicine. The Clinical Sequencing Exploratory Research (CSER) consortium includes 18 extramural research projects, one National Human Genome Research Institute (NHGRI) intramural project, and a coordinating center funded by the NHGRI and National Cancer Institute. The consortium is exploring analytic and clinical validity and utility, as well as the ethical, legal, and social implications of sequencing via multidisciplinary approaches; it has thus far recruited 5,577 participants across a spectrum of symptomatic and healthy children and adults by utilizing both germline and cancer sequencing. The CSER consortium is analyzing data and creating publically available procedures and tools related to participant preferences and consent, variant classification, disclosure and management of primary and secondary findings, health outcomes, and integration with electronic health records. Future research directions will refine measures of clinical utility of CGES in both germline and somatic testing, evaluate the use of CGES for screening in healthy individuals, explore the penetrance of pathogenic variants through extensive phenotyping, reduce discordances in public databases of genes and variants, examine social and ethnic disparities in the provision of genomics services, explore regulatory issues, and estimate the value and downstream costs of sequencing. The CSER consortium has established a shared community of research sites by using diverse approaches to pursue the evidence-based development of best practices in genomic medicine.

Clinical tumor sequencing: opportunities and challenges for precision cancer medicine

Advances in tumor genome sequencing have enabled discovery of actionable alterations leading to novel therapies. Currently, there are approved targeted therapies across various tumors that can be matched to genomic alterations, such as point mutations, gene amplification, and translocations. Tools to detect these genomic alterations have emerged as a result of decreasing costs and improved throughput enabled by next-generation sequencing (NGS) technologies. NGS has been successfully utilized for developing biomarkers to assess susceptibility, diagnosis, prognosis, and treatment of cancers. However, clinical application presents some potential challenges in terms of tumor specimen acquisition, analysis, privacy, interpretation, and drug development in rare cancer subsets. Although whole-genome sequencing offers the most complete strategy for tumor analysis, its present utility in clinical care is limited. Consequently, targeted gene capture panels are more commonly employed by academic institutions and commercial vendors for clinical grade cancer genomic testing to assess molecular eligibility for matching therapies, whereas whole-exome and transcriptome (RNASeq) sequencing are being utilized for discovery research. This review discusses the strategies, clinical challenges, and opportunities associated with the application of cancer genomic testing for precision cancer medicine.

Precision medicine in breast cancer: genes, genomes, and the future of genomically driven treatments

Remarkable progress in sequencing technology over the past 20 years has made it possible to comprehensively profile tumors and identify clinically relevant genomic alterations. In breast cancer, the most common malignancy affecting women, we are now increasingly able to use this technology to help specify the use of therapies that target key molecular and genetic dependencies. Large sequencing studies have confirmed the role of well-known cancer-related genes and have also revealed numerous other genes that are recurrently mutated in breast cancer. This growing understanding of patient-to-patient variability at the genomic level in breast cancer is advancing our ability to direct the appropriate treatment to the appropriate patient at the appropriate time--a hallmark of "precision cancer medicine." This review focuses on the technological advances that have catalyzed these developments, the landscape of mutations in breast cancer, the clinical impact of genomic profiling, and the incorporation of genomic information into clinical care and clinical trials.

Treatment Algorithms Based on Tumor Molecular Profiling: The Essence of Precision Medicine Trials

With the advent of high-throughput molecular technologies, several precision medicine (PM) studies are currently ongoing that include molecular screening programs and PM clinical trials. Molecular profiling programs establish the molecular profile of patients' tumors with the aim to guide therapy based on identified molecular alterations. The aim of prospective PM clinical trials is to assess the clinical utility of tumor molecular profiling and to determine whether treatment selection based on molecular alterations produces superior outcomes compared with unselected treatment. These trials use treatment algorithms to assign patients to specific targeted therapies based on tumor molecular alterations. These algorithms should be governed by fixed rules to ensure standardization and reproducibility. Here, we summarize key molecular, biological, and technical criteria that, in our view, should be addressed when establishing treatment algorithms based on tumor molecular profiling for PM trials.

Impact of a prospective review program for reference laboratory testing requests

OBJECTIVES

To control the cost of reference laboratory testing, to ensure that its usage is medically appropriate, and to review the contribution of reference testing to patient care at our institution.

METHODS

A multidisciplinary institutional committee was convened to manage the utilization of reference testing. A subset of tests was designated to be reviewed in real time by a team of clinical pathologists in consultation with clinical subject matter experts.

RESULTS

Twelve percent of testing requests, accounting for approximately 18% of send-out costs, were determined to be clinically unnecessary or would not produce actionable results at that point during that patient's care and were therefore not performed. This intervention, combined with insourcing of frequently requested tests, resulted in a reduction in the costs of reference testing to less than half of that predicted by the rate of growth from 2005 to 2009. Molecular diagnostic tests displayed a higher cost per test than other forms of testing but had a similar degree of clinical impact.

CONCLUSIONS

Formal prospective review of reference laboratory testing requests resulted in substantial cost containment and improved the efficiency of patient care.

Personalizing Medicine in Head and Neck Squamous Cell Carcinoma: The Rationale for Combination Therapies

Personalized medicine, in which individual tumor genetics drive the selection of targeted therapies and treatment plans for each patient, has recently emerged as the next generation of cancer therapy. Unfortunately, personalized medicine trials have had limited success in tumors that have complex combinations of disruptive genomic events, which drive differential responses to targeted therapies. Here, we will use head and neck squamous cell carcinoma as a model for genetically complex disease and discuss novel approaches to enhance personalized medicine trials for these complicated cases.

Personalized oncology: genomic screening in phase 1

Improvements in cancer genomics and tumor biology have reinforced the evidence of cancer development driven by numerous genomic alterations. Advanced genomics technology can be used to characterize genomic alterations that potentially drive tumor growth. With the possibility of screening thousands of genes simultaneously, personalized molecular medicine has become an option. New treatments are being investigated in phase 1 trials around the world. Traditionally, the goal of phase 1 studies was to determine the optimal dose and assess dose-limiting toxicity of a potential new experimental drug. Only a limited number of patients will benefit from the treatment. However, introducing genomic mapping to select patients for early clinical trials with targeted molecular therapy according to the genomic findings, may lead to a better outcome for the patient, an enrichment of phase 1 trials, and thereby accelerated drug development. The overall advantage is to determine which mutation profiles correlate with sensitivity or lack of resistance to specific targeted therapies. The utility and current limitations of genomic screening to guide selection to Phase 1 clinical trial will be discussed.
