Health economics theory and methods can contribute to many open questions to improve survivorship. METHODS: In this paper, we review key areas where more research is needed and describe strategies for improving data infrastructure, research funding, and capacity building to strengthen survivorship health economics research. CONCLUSIONS: Health economics has broadened an understanding of key supply- and demand-side factors that promote cancer survivorship. To ensure necessary research in survivorship health economics moving forward, we recommend dedicated funding, inclusion of health economics outcomes in primary data collection, and investments in secondary data sets.

A breakout session, Methods and Study Design for Cancer Health Economics Research, was convened at the Future of Cancer Health Economics Research Conference to discuss 2 commonly used analytic tools for cancer health economics research: observational studies and decision-analytic modeling. Observational studies include analysis of data collected with the primary purpose of supporting economic evaluation or secondary use of data collected for another purpose. Modeling studies develop a parametrized structure, such as a decision tree, to estimate hypothetical impact. Whereas observational studies focus on what has happened and why, modeling studies address what may happen. We summarize the discussion at this breakout session, focusing on 3 key elements of high-quality cancer health economics research: study design, analytical methods, and addressing uncertainty.

This commentary outlines a set of research recommendations stemming from the National Cancer Institute's Future of Health Economics Research Conference to better understand and reduce patient economic burden as part of cancer care delivery. Currently, there are a lack of detailed metrics and measures of survivors' OOP costs and employment disruption, and data on these costs are rarely available at the point of care to guide patient-centered treatment and survivorship care planning. Future research should improve the collection of data about survivors' OOP costs for medical care, other cancer-related expenses, and experiences of employment disruption. Methods such as microcosting and the prospective collection of patient-reported outcomes in cancer care are needed to understand the true sum of cancer-related costs taken on by survivors and caregivers. Better metrics and measures of survivors' costs must be coupled with interventions to incorporate that information into cancer care delivery and inform meaningful communication about OOP costs and employment disruption that is tailored to different clinical situations. Informing survivors about the anticipated costs of their cancer care supports informed decision making and proactive planning to mitigate financial hardship. Additionally, system-level infrastructure should be developed and tested to facilitate screening to identify survivors at risk for financial hardship, improve communication about OOP costs and employment disruption between survivors and their health-care providers, and support the delivery of appropriate financial navigation services.

We searched PubMed for systematic and other reviews with the Medical Subject Headings "neoplasms" and "economics" published between January 1, 2010, and April 1, 2020, identifying 164 reviews. Review characteristics were abstracted and described. The majority (70.7%) of reviews focused on cost-effectiveness or cost-utility analyses. Few reviews addressed other types of cancer health economic studies. More than two-thirds of the reviews examined cancer treatments, followed by screening (15.9%) and survivorship or end-of-life (13.4%). The plurality of reviews (28.7%) cut across cancer site, followed by breast (20.7%), colorectal (11.6%), and gynecologic (8.5%) cancers. Specific topics addressed cancer screening modalities, novel therapies, pain management, or exercise interventions during survivorship. The results indicate that reviews do not regularly cover other phases of care or topics including financial hardship, policy, and measurement and methods.

The workgroup identified 3 broad categories of focus: data limitations, opportunities for training for clinicians and health economists interested in collaboration, and the need for prospective economic study of cancer treatment. Within these areas of focus, the workgroup recommended the following: improvement of the availability of key economic measures in data available to researchers, creation of more comprehensive datasets robust to insurance type or coverage, development of cancer care health economics research-focused symposia, instituting clear mechanisms to support integration of economic analyses alongside clinical trials, development of standardized methods to measure the cost of cancer care to health-care systems and patients, and development of standardized evaluations that include measures of social determinants of health.

This paper draws attention to how health economics research can assess strategies to reduce or even eliminate health disparities and provides pivotal examples of existing research as well as areas for future contributions. The paper also highlights critical data limitations that currently restrain the impact health economics research could have. We then explore new areas of inquiry where economic research is sparse but could have an important impact on health equity, particularly in topics involving Medicare and Medicaid policies that expand reimbursement and generosity of coverage. Health economics studies are notably absent from policies and practices surrounding clinical trials, representing an opportunity for future research. We urge health economics researchers to consider experiments, interventions, and assessments through primary data collection; we further encourage the formulation of multidisciplinary teams to ensure that health economics skills are well melded with other areas of expertise. These teams are needed to maximize novelty and rigor of evidence. As policies are promulgated to address disparities in cancer, involvement of economics in a multidisciplinary context can help ensure that these policies do not have unintended impacts that may deepen inequities.

Health economics offers the theoretical foundation and research methodology to understand the demand- and supply-side factors associated with screening and evaluate screening-related policies and interventions. This article provides an overview of health economic theories and methods related to cancer screening and discusses opportunities for future research. We review 2 academic disciplines most relevant to health economics research in cancer screening: applied microeconomics and decision science. We consider 3 emerging topics: cancer screening policies in national as well as local contexts, "choosing wisely" screening practices, and targeted screening efforts for vulnerable subpopulations. We also discuss the strengths and weaknesses of available data sources and opportunities for methodological research and training. Recommendations to strengthen research infrastructure include developing novel data linkage strategies, increasing access to electronic health records, establishing curriculum and training programs, promoting multidisciplinary collaborations, and enhancing research funding opportunities.

This manuscript qualitatively summarizes cannabis policies across states with legal adult use marketplaces. METHODS: Data are from state laws and regulations, collected through January 2021, and have been verified with state officials as part of ongoing state policy tracking efforts. RESULTS: State policies differ in how cannabis products are taxed, where revenues are allocated, restrictions on the types of available products, restrictions on additives and flavors, product packaging and labeling, advertising restrictions, where cannabis can be consumed, and approaches to social equity. CONCLUSION: Timely, accurate, and longitudinal state and local cannabis policy data are needed to understand the implications of legalization. Careful study of policy differences across and within states is warranted, as differences may affect public health and consumer safety.

Their promise as broad-based antitumor agents in preclinical models has led to the initiation of pilot clinical trials. Session 5 of the National Cancer Institute's Cannabis, Cannabinoids and Cancer Research Symposium provides an overview of this research topic. Overall, the presentations highlight cannabinoid signal transduction and specific molecular mechanisms underlying cannabinoid antitumor activity. They also demonstrate the broad-based antitumor activity of the plant-based, synthetic, and endogenous cannabinoid compounds. Importantly, evidence is presented demonstrating when cannabinoids may be contraindicated as a treatment for cancer, as in the case of human papilloma virus-meditated oropharynx cancer or potentially other p38 MAPK pathway-driven cancers. Finally, it is discussed that a key to advancing cannabinoids into the clinic is to conduct well-designed, large-scale clinical trials to determine whether cannabinoids are effective antitumor agents in cancer patients.

Discussion next turned to the evolution of the legal landscape of cannabis in the United States, one in which state and federal laws frequently conflict and the Controlled Substance Act renders cannabis Schedule I. This legal climate creates conundrums for US medicinal cannabis researchers who contend with limited funding opportunities, avenues to source trial drug, and procedural red tape and for oncology clinicians who recommend medicinal cannabis to patients with some frequency while perceiving themselves as ill equipped to make such clinical recommendations. Ultimately, it creates challenges for cancer patients who find themselves turning to nonmedical and anecdotal information sources. The risks of cannabis use by the cancer patient were discussed next. These include infection, pharmacodynamic and pharmacokinetic drug-botanical interactions, cyclic nausea and vomiting, e-cigarette or vaping product use-associated illness, legal issues, and high cost. The session concluded with a broad survey of the research supporting oncologic cannabinoid use, conclusive evidence for chemotherapy-induced nausea and vomiting, and suggestive evidence for cancer-related pain.

Co-use of tobacco and cannabis is common. Smoke from cannabis contains many of the same carcinogens and toxicants as the smoke from tobacco, raising concerns that cannabis smoking may be a risk factor for cancer. With growing access to and acceptance of medical and nonmedical cannabis, there is an urgent need to understand the risks and benefits of the current modes of cannabis use and how cannabis may be associated with cancer risk. This monograph summarizes a session from a National Cancer Institute Symposium on nonmedical cannabis use and cancer risk. We had 3 objectives: describe the relation between nonmedical cannabis use and cancer risk, delineate patterns and correlates of cannabis co-use with tobacco, and document potentially harmful inhalational exposure resulting from smoked and vaped cannabis. Methodological limitations in the literature and future research recommendations are provided.

Specific symptoms of pain, nausea and vomiting, loss of appetite and cachexia, anxiety, sleep disturbance, and medical trauma are among those that have prompted patients with cancer to use cannabis. This conference report from the National Cancer Institute's "Cannabis, Cannabinoid and Cancer Research Symposium" on the topic of "Cancer Symptom/Treatment Side Effect Management" is an expert perspective of cannabis intervention for cancer and cancer treatment-related symptoms. The purpose of the symposium was to identify research gaps, describe the need for high-quality randomized prospective studies of medical cannabis for palliative care in patients with cancer, and evaluate the impact of medical cannabis on cancer survivors' quality of life. Further, education of clinicians and affiliated health-care providers in guiding cancer patients in using cannabis for cancer care would benefit patients. Together, these steps will further aid in refining the use of cannabis and cannabinoids for symptom palliation and improve safety and efficacy for patients.

With widespread availability of novel cannabis and cannabis-based products, there is an urgent need to understand their safety and effectiveness for medical indications. Three primary barriers contribute to the difficulty in initiating research geared toward answering the most pressing public health questions: the US regulatory status of cannabis and cannabinoids, sources for cannabis and cannabinoid study medications, and limited funding and resources to support studies. Despite these hurdles, research is rapidly increasing, and recent changes in the United States have paved the way for exciting new work. Here, challenges and barriers to cannabis and cannabinoid research are described from the perspectives of the National Institute on Drug Abuse, National Institutes of Health; the US Food and Drug Administration; and 2 clinical researchers. Barriers specifically to studying cannabis, cannabinoids, and cancer are emphasized.

The National Cancer Institute (NCI) has supported cannabis-related research projects and funding opportunity announcements. In addition, NCI organized a virtual symposium on December 15-18, 2020, to discuss recent research findings on the use of cannabis and cannabinoids in relationship to cancer risk, prevention, and care. Specifically, the symposium sought to highlight the state of the science regarding cannabis, including the chemical constituents of cannabis (eg, cannabinoids), and cancer research involving cannabis, including cancer epidemiology, use in cancer patients, cancer biology and prevention, and preclinical and clinical cancer symptom and treatment side effect management with cannabis and cannabinoids as therapeutics. The symposium identified promising areas of future study, current barriers to conducting the research, and strategies to overcome those barriers. The series of papers in this special edition provide a summary of the symposium sessions as well as a synopsis of opportunities and challenges related to conducting research in this area.

Cannabinoids appear to induce apoptosis in rodent brain tumors by way of direct interaction with the cannabinoid receptor. They may inhibit angiogenesis and tumor cell invasiveness. Despite preclinical findings, attempts to translate the benefits from bench to bedside have been limited. This session provides a review of the basic science supporting the use of cannabinoids in gliomas, paired with the first randomized clinical trial of a cannabis-based therapy for glioblastoma multiforme. Another preclinical presentation reports the effects of cannabinoids on triple-negative breast cancer cell lines and how cannabidiol may affect tumors. The session's second human trial raises concerns about the use of botanical cannabis in patients with advanced cancer receiving immunotherapy suggesting inferior outcomes.

To date, the US Food and Drug Administration has approved 2 cannabis-based pharmacotherapies for the treatment of cancer chemotherapy-associated adverse effects: dronabinol and nabilone. Over the proceeding decades, both research investigating and societal attitudes toward the potential utility of cannabinoids for a range of indications have progressed dramatically. The following monograph highlights recent preclinical research focusing on promising cannabinoid-based approaches for the treatment of the 2 most common adverse effects of cancer chemotherapy: chemotherapy-induced peripheral neuropathy and chemotherapy-induced nausea and vomiting. Both plant-derived and synthetic approaches are discussed, as is the potential relative safety and effectiveness of these approaches in relation to current treatment options, including opioid analgesics.

Mitigating financial hardship requires multi-level solutions at the policy, payer, health-care system, provider, and individual patient levels. At the highest level, strategies for intervention include enacting policies to improve price transparency and expand insurance coverage. Also needed are implementing systematic screening and financial navigation in cancer care delivery; improving cost communication by provider care teams; developing patient-reported measures that incorporate the multiple, complex dimensions of financial hardship, as reflected in the Economic Strain and Resilience in Cancer tool; and advancing electronic medical record infrastructure to manage data on patient financial hardship. For individual patients, activating their social networks, community resources, and employers provides patient-level support resources to enhance coping. The proposed multi-level approach is needed to overcome financial hardship in the setting of high-quality, high-value cancer care delivery.

The required domains to meet the health needs of cancer survivors were outlined in the report: cancer surveillance and screening, cancer prevention and lifestyle counseling, management of treatment related persistent or late effects, coordination of care, and psychosocial support services. In response to that report, The University of Texas MD Anderson Cancer Center implemented a tiered survivorship care model that is risk based. The core principle is that cancer survivors' health needs will depend on the cancer treatment and disease-specific risks. We here describe this model for low-, intermediate-, and high-risk cancer survivors, in which comanagement between oncology and primary care providers is risk dependent. Our clinical model defines transition as appropriate when there is a minimal risk of primary cancer relapse, which is specific to each cancer type and disease stage. This model is embedded into disease-specific clinical practice algorithms, aligned with the IOM domains of care. Over the past 10 years, we have successfully transitioned nearly 25 000 patients to disease-specific survivorship clinics, providing care based on the IOM domains. We have learned from our process that expansion of survivorship care into established clinical settings requires engagement of champions and key clinical stakeholders. Future directions for survivorship care should explore the application and potential benefits of telemedicine as a care delivery system to meet the needs of cancer survivors.

Technology can aid the delivery of personalized, stratified survivorship care pathways where the intensity of care, the care setting, and the providers required for that care vary with survivors' needs. Building a cancer data ecosystem of connected data streams that supports and learns from each patient can be used to streamline care, enhance efficiency, reduce costs, and facilitate research. This manuscript describes the input, analytics, and output components of the cancer data ecosystem that must be built and connected and also provides a real-world use case of how such a system could transform care in a large US comprehensive cancer center.
