Abstract
The need for cancer professionals has never been more urgent than it is today. Reports project serious shortages by 2020 of oncology health care providers. Although many plans have been proposed, no role for prevention has been described. In response, a 2-day symposium was held in 2009 at The University of Texas MD Anderson Cancer Center to capture the current status of the cancer prevention workforce and begin to identify gaps in the workforce. Five working groups were organized around the following topic areas: (a) health policy and advocacy; (b) translation to the community; (c) integrating cancer prevention into clinical practice; (d) health services infrastructure and economics; and (e) discovery, research, and technology. Along with specific recommendations on these topics, the working groups identified two additional major themes: the difficulty of defining areas within the field (including barriers to communication) and lack of sufficient funding. These interdependent issues synergistically impede progress in preventing cancer; they are explored in detail in this synthesis, and recommendations for actions to address them are presented. Progress in cancer prevention should be a major national and international goal. To achieve this goal, ensuring the health of the workforce in cancer prevention and control is imperative.

Cancer Prevention: Where Are We Now?
In warning the public about a projected critical shortage of medical oncologists in the USA by 2020 [1], the 2007 study commissioned by the American Society for Clinical Oncology (ASCO) stimulated consideration of the unrecognized potential for cancer prevention efforts by its exclusion from the report. It also raised concern that the field of cancer prevention and control was at risk for a similar workforce shortage in the future [2]. The ASCO report described factors that contribute to the impending medical oncology shortage. These include growth in the number of Baby Boomers at increased risk for cancer, in the number of oncologists eligible for retirement, and in the number of cancer survivors with long-term care needs, as well as the decline in the number of physicians choosing careers in oncology [1]. Using statistical models to test various workforce strategies, ASCO reported that given time and resource constraints for preparing oncologists, simply training more individuals would not address the shortage projected for 2020. Clearly, raising concern regarding the workforce that will manage the future burden of cancer was not misguided.
Since 2007, much has taken place. Soliciting recommendations to address the shortfall, ASCO created and approved a strategic plan in 2008 [3]. Some aspects of ASCO’s three-goal plan have already been implemented. These include creating a workforce advisory committee [3], providing grant awards to study workforce issues in partnership with Susan G. Komen for the Cure Foundation [4], conducting pilot projects to test innovative practice models and demonstration projects to build partnerships between oncologists and physician extenders [5], and submitting a statement to the US Senate Health, Education, Labor, and Pensions Committee hearing on health-care workforce initiatives [6]. In spite of these steps to address the oncology workforce shortage, major opportunities to achieve progress against cancer through prevention continue to be missed, as most reports do not consider the impact of cancer prevention activities. Such omission may result from lack of awareness, skepticism of the impact of prevention, or the dearth of information available for describing the infrastructure of cancer prevention and control and its workforce [2]. Regardless, if cancer prevention activities are to alleviate the future burden of cancer on our society, their visibility must be raised.
Lessons from Public Health and Medicine
More than a decade ago, concerns were raised about threats to the public health workforce [7]. Many of these threats impeded description of the public health workforce. A multidisciplinary field that involves many different types of workers, public health comprises formally trained professionals to individuals trained on-the-job, making identification of the individual job descriptions within the workforce difficult [8]. Furthermore, public health activities span basic research to applied practice and take place in a variety of settings (e.g., schools, communities, hospitals, and universities) at different levels (i.e., local, state, and national). They also involve numerous partners such as governmental agencies, non-profit foundations, universities, health-care organizations, private sector partners, and professional membership societies. The field of public health has struggled to create a universal, clearly defined identity for itself, with common language, goals, and standards. Metrics and infrastructure for workforce surveillance and forecasting were lacking, which stimulated enumeration efforts [9]. Since then, important progress has been made. Motivated by research agendas set for studying the public health workforce (Table 1) [8, 10], a body of literature now exists that has benefited over time from improved coordination of efforts (e.g., Office of Workforce and Career Development within Office of the Centers for Disease Control Director), creation of common definitions, surveillance of workforce data (e.g., HRSA), development of resources, methods and models for forecasting and evaluating the public health workforce, including for policy analysis, as well as dissemination and translation of findings into effective changes [8]. These challenges to clear characterization of the public health workforce are similar to those facing cancer prevention and control today.
Farther along in understanding its workforce, medicine has maintained a rigorous infrastructure for workforce surveillance through several organizations, including the American Medical Association, the Association of American Medical Colleges (AAMC), and the Accreditation Council for Graduate Medical Education. For example, AAMC has maintained national databases of medical schools, applicants, students, graduates, and faculty since 1966. They have described these resources in terms of their racial and ethnic diversity, gender, student admissions, and faculty recruitment, retention, salaries, and promotions. The ability of the AAMC to analyze available data collected annually from more than 130 medical schools across the USA and Canada has resulted in a rich literature documenting the health of its workforce from a variety of perspectives that has kept attention focused on anticipated workforce shortages in medicine.
Far from being distinct from medicine and public health, cancer prevention and control shares goals and professionals with both. However, cancer prevention has unique features as well. It extends beyond the primary interest of public health, the health of populations, to include focus upon individual patients, like medicine. In contrast to public health and medicine, the field of cancer prevention is specific in its mission to a single disease around which its stakeholders can concentrate their efforts, whereas stakeholders in public health and medicine more often express their support for specific aspects of public health (e.g., vaccinations) or affiliation with specific types of practitioners (e.g., pediatricians), rather than to the broader missions of public health and medicine at large. Medicine has articulated competencies that serve as the basis for all training, board certification, and licensing across the USA. For the cancer workforce, C-Change, a non-profit organization oriented to eliminating and preventing cancer, has created “Cancer Core Competencies” [11, 12], as part of a larger initiative to address cancer workforce issues, but these competencies are not widely recognized within the field. Thus, while much remains to be done in both public health and medicine, the field of cancer prevention and control can profit from advances made in these and other fields to understand and address issues faced by its own workforce.
“The Future Directions in Cancer Prevention and Control: Workforce Implications for Training, Practice, and Policy” Symposium
In 2009, a group of cancer prevention and control professionals organized a 2-day symposium at The University of Texas MD Anderson Cancer Center, with the objective of capturing the current status of the cancer prevention workforce and beginning to identify gaps in the workforce. Five working groups were organized around topic areas: (a) health policy and advocacy; (b) translation to the community; (c) integrating cancer prevention into clinical practice; (d) health services infrastructure and economics; and (e) discovery, research, and technology. Following the symposium, these groups formed writing groups to develop manuscripts about workforce issues relevant to the topic areas. Trainees attending the symposium through sponsored scholarships helped facilitate writing groups and collaborated to produce a meeting report [13]. A group addressing the perspective of nurses in cancer prevention was added later, and the health policy and advocacy group was reorganized to write the article included in this supplement. In total, six manuscripts are included in this supplement together with this synthesis and other materials and information from the symposium. Each article reflects the perspectives and experiences of the authors and their knowledge of the literature and available resources. They are offered here as a means to stimulate dialogue about workforce issues in the field of cancer prevention and control.
Themes from Writing Groups
In addition to the unique ideas and recommendations presented in each article, two major themes emerged from the writing groups: the difficulty of defining areas within the field (including the barriers to communication and the difficulties created), and the lack of sufficient funding. These interdependent themes, along with their sequelae, synergistically impede progress in preventing cancer.
Definitions in Cancer Prevention and Control
The field of cancer prevention and control includes a diversity of disciplines from basic sciences to population-based research, such as biostatistics, epidemiology, and behavioral science, as well as a multitude of interventions to be disseminated into community and clinical practice, all of which are united only by its defining goal—to prevent cancer. The research in these disciplines varies substantially, by study design, population focus, or model system (e.g., genetic and molecular factors, cell lines, animal models, and humans), by research methods and tools, and by technical language. Thus, a challenge to professionals within the field is communicating across disciplines, especially when different terms are used to describe similar concepts and when similar terms have different meanings. The challenge is made more complex when collaborations involve professionals from disciplines outside the field who have not previously been oriented to the goals or methods of cancer prevention.
Several consequences result from poor communication, one of the most serious being lack of awareness of potential cross-disciplinary collaborations. For example, professionals outside cancer prevention may not realize that their skills and expertise are relevant to cancer prevention and control. Conversely, those working in cancer prevention may not recognize the potential gains from collaborating with those outside the field (or know how to reach them), such as exposure to new approaches and methods and specialized technology, resources, and perspectives that could infuse the field with fresh ideas and energy. Without good communication, those within the field of cancer prevention and control risk isolation and missed opportunity for innovative thinking. Moreover, if information about activities within the field is not communicated externally, risk for wasteful duplication of resources and efforts in cancer prevention is greater. Altogether, these consequences of poor communication slow the pace of discovery and progress within the field.
Poor communication within the field impedes clear and uniform definition of emerging areas of focus, a critical issue for new areas to organize successfully and be nurtured. For such areas of emphasis to thrive, the individuals involved in those areas must be able to identify one another, which may be difficult if the fields are labeled differently (e.g., “cancer prevention health services research” vs. “comparative effectiveness in cancer prevention”). Not knowing about colleagues with similar interests because they describe themselves differently impedes collaborations, development of methods and resources, and generation of interest around the subject matter or topic area. In this era of team science, rare is the occasion when a major breakthrough is achieved in isolation. Without commonly defined goals, individuals may lack orientation to the most critical issues to be addressed, diluting impact, and progress in cancer prevention. This problem may be especially detrimental to those early in their careers because junior scientists may compete more easily for resources in emerging areas than in those with established experts. If it is difficult for junior scientists to identify such emerging areas then they cannot take advantage of them. Clear definitions are also critical for funding agencies to recognize promising new directions for cancer prevention, as well as to support training in such areas. Only once sufficient momentum is gained can more rapid discovery and advancement be possible, and emerging areas become established.
The Cancer Prevention Workforce and Poor Communication
Poor communication affects the cancer prevention workforce in several ways. First, awareness of the career opportunities in the field of cancer prevention is lacking among both students and those who provide career advice to them. Most students are aware of careers in medicine, nursing, and public health practice, as well as of careers in biological, public health, and behavioral science research, but many may not connect these careers with opportunities in cancer prevention. Research on the Millenial generation suggests that young people obtain information about careers and make career decisions differently than previous generations, with a focus on initial searches through the Internet, a preference for “branded” employers and direct contact with decision-makers in target organizations, and a strong preference for individualized, tailored career development assistance. Because students ignorant of career opportunities in cancer prevention will not seek them out, raising the profile of cancer prevention careers is vital. Unfortunately, exposure of health professional students to cancer prevention careers during training remains low. For example, over the past 20 years since efforts by the American Association for Cancer Education have sought to assess and integrate cancer prevention education into undergraduate medical education, and in spite of recommendations by the IOM [13], recent review of medical school curricula suggests only modest success achieved [14]. Improved efforts to raise awareness among medical students could have potent impact, as 57% of entering oncology fellows surveyed by ASCO reported deciding to pursue oncology before residency [15]. Medical school represents a critical window of opportunity for influencing physician career choices, as oncology competes with other subspecialties for those boarded in internal medicine [16]. Using a variety of strategies, including new methods of communication (e.g., social media), students must be engaged more effectively and exposed to cancer prevention careers earlier in their education.
For those already interested in cancer prevention careers, part of the problem may be structural, in that no clear career path into the field exists for students to follow. For example, no specialty or subspecialty is currently dedicated to providing training in cancer prevention. Medical students hoping to pursue accredited post-graduate medical training relevant to clinical cancer prevention are limited to choosing either preventive medicine specialty, which does not focus exclusively on cancer, or internal medicine subspecialty in oncology, which does not focus exclusively on prevention.
Some learn about cancer prevention later in their careers, sometimes after years of practice in basic science and clinical work in oncology. If knowledge of careers in cancer prevention comes later during the training trajectory, fatigue from lengthy training or lack of interest in returning to status as students or trainees may deter some, even if they are interested in careers in cancer prevention. Moreover, debt accrued from medical training, while not consistently shown to influence choice of specialty [17], may discourage those seeking additional training in cancer prevention, especially if it comes after other required career preparation. The National Cancer Institute (NCI) is interested in building the cancer prevention workforce and provides funding for training and career development awards designed to attract professionals into research careers in cancer prevention [18]. While these have been successful and have launched the careers of many researchers, the methods for recruiting individuals into the field are left to free-market competition. At any rate, by not creating highly visible and desirable career paths into cancer prevention and control, we may already be losing excellent individuals.
Insufficient Funding in Cancer Prevention and Control
A second major barrier to achieving success in cancer prevention and control that the writing groups cited often was insufficient funding. Indeed, in 2010, while the NCI spent 31.7% for research in cancer causation, detection, and diagnosis and 22.7% for treatment research, a total of 7.1% of the NCI annual budget was allocated for cancer prevention and control [19]. This reflects a decreasing trend over time in the proportion of the total budget for funds specifically allocated for cancer prevention and control, which was 10.7% in 2006, 10.4% in 2007, and 9.9% in 2008 before the budget mechanism for cancer prevention and control was eliminated altogether in 2009. Of course, the NCI is not the only source of funding for cancer prevention and control activities. Many other federal agencies and philanthropic organizations, both large and small, contribute to supporting activities to prevent cancer. In spite of these collective efforts, progress in cancer prevention and control, regardless of funds expended, remains moderate at best.
The perception of the writing groups that insufficient funding forms a major barrier to cancer prevention is natural given the breadth of disciplines within the field, and the wide scope of activities and their complexity that fall under the rubric of cancer prevention and control. For research, the ability to pursue more ambitious goals at a faster pace than in past has been facilitated by major advances in technology, including computing, robotics, and faster, easier to use, and omnipresent tools for communication. These have increased the pace of research, but not always decreased its cost. Moreover, discoveries in cancer prevention research that are translated into effective interventions may have associated costs as well, such as for procedures, for tests or assays, or personnel effort and time to deliver educational and behavioral change strategies. Of course, the more intractable that major cancer risk factors are, such as inherited susceptibility to cancer, tobacco use, and obesity, the greater the resources needed to address them successfully may be, but also the more the professional community and the public may want efforts redoubled. Gaining headway against such risk factors may be especially challenging due to the complex etiology of these conditions. Of course, cancer prevention professionals endure constant pressure from the public’s desire for easy and low-cost methods to prevent cancer with little or no side-effects.
A long-standing problem to clinical implementation of proven cancer prevention strategies has been limited reimbursement for conducting cancer prevention activities. The proportions of oncologists reporting “insufficient reimbursement for prevention activities in clinical practice” as a barrier to cancer prevention did not change substantially, from 65% to 63%, in the 15 years between surveys conducted in 1989 and 2004 [20, 21]. Such a report is disappointing in light of the advances in cancer prevention achieved to date. Other advances pose cost-related challenges as well. For example, the exciting results in 2011 demonstrating the effectiveness of CT screening for lung cancer early detection reported from the National Lung Screening Trial [22] raises many cost-related issues about who should be screened and how often, as well as whether the cost of regular screening will be prohibitively expensive and who will pay for it [23]. It is to be expected that policies to reimburse for specific cancer prevention services will always lag behind the development of scientific discoveries into tools that are proven effective; however, the decision-making process by which policy makers, patient advocates, insurers, and health-care providers determine which services to include in cancer prevention coverage may need improvement in order to have greater impact on the burden of cancer [13].
Funding for Training the Cancer Prevention Workforce
Funding for recruiting and preparing the professional workforce in cancer prevention and control exists. In 2010, the NCI allocated 3.5% of its annual budget ($179,346,000) to research manpower development [19]. This amount encompasses support for all research training in cancer, including for cancer prevention and control scientists. Of the 17 extramural training and educational award mechanisms listed on the NCI’s Center for Cancer Training’s website, three specifically provide support for individuals and one for institutions to support multiple trainees in cancer prevention research training. The total amount in 2010 for individual awards was $21.4 M (21 K05 awards at $3.1 M; 97 K07 awards at $13.3 M; and 30 K05 awards at $5.0 M) and for the 44 institutional R25T awards, the total amount was $20.4 M [24], equaling 23.3% for cancer prevention of the total amount spent by NCI on developing the research workforce. The NCI portfolio comprises only a portion of the support expended in the USA for training and education in cancer prevention and control; other arms of the NIH, other federal agencies (e.g., AHRQ, DOD, and CDC), non-profit foundations (e.g., American Cancer Society, Prevent Cancer Foundation, AICR), and even for-profit companies also provide support for training and education in cancer research. In 2001, the American Cancer Society estimated that approximately 20% of its total spending in training and career development was dedicated to cancer prevention, between $2 and $3 M annually [13]. In Texas, the Cancer Prevention and Research Institute of Texas (CPRIT) has funded 350 awards since 2010 for more than $570 M, of which 12 of 27 were in prevention education, for a total of $5.5 M. This amount represents 57% of the total $9.7 M awarded for prevention activities or 0.97% of all CPRIT funds awarded to date [25]. To recruit and retain individuals in cancer careers, a recent partnership between the American Society for Clinical Oncology and the Susan G. Komen for the Cure Foundation provides loan repayment for oncologists from populations underrepresented in medicine committed to serving medically underserved communities [26, 27].
The availability of such funds represent a major commitment to preparing the next generation of cancer professionals; however, it is unclear whether the total amount of funds dedicated to training cancer prevention professionals—either in Texas or across the nation—is sufficient to staff and serve the growing needs for cancer prevention and control, particularly in proportion to other public health issues. Indeed, one indicator that funding may be insufficient comes from the long-standing and alarming steady decline in numbers of physicians serving in public health leadership [13]. Also, residency programs in preventive medicine are shrinking, both in total number, from 90 programs in 1999 to 72 in 2012, and in the annual number of residents in training, down 15% since 2001 [28, 29], partly because nearly half of available training positions are left unfilled due to insufficient funding [30]. Supporting residency programs in preventive medicine is particularly challenging. Unlike all other residency programs that qualify for support from Medicare Graduate Medical Education because they are hospital based, preventive medicine residency programs do not receive Medicare funding because preventive medicine residents are typically trained outside hospitals [30]. While graduate medical training in both preventive medicine and oncology includes some exposure to cancer prevention and control, overcoming the challenges to funding training in prevention for health-care providers is critical to having sufficient numbers in the cancer prevention and control workforce.
In spite of the funding awarded to date for training in cancer prevention and control, the writing groups opined that too few training programs in cancer prevention and control existed overall, and that too few existed to populate specific areas of need within the field. Indeed, in 1999, the NCI reshaped the focus of its R25T award program in response to its perceived need to populate cancer research with professionals prepared to participate in multidisciplinary research [13]. This award mechanism is well-suited to the types of cross-disciplinary projects and environments that are the norm in cancer prevention and control, and has facilitated a more vigorous effort to recruit researchers into the field. Of the 43 awards active in 2010, 22 allow for research training in a variety of areas within cancer prevention and 11 focus on specific aspects, such as behavioral science, nutrition, genetics, or tobacco [24]. Such programs provide fellowship support for those learning how to conduct research in cancer prevention through basic science, population and behavioral science, and clinical translation. The R25T programs differ from other NIH-funded training programs (e.g., Kirschstein NSRA T32 awards) in that they require trainees to have a minimum of two mentors with complementary expertise to facilitate development of cross-disciplinary research skills (NCI R25T PAR-10-165). Careful nurturing of trainees preparing for such multidisciplinary careers is required if the educational and research experiences provided are not to revert to uni-disciplinary training or to be diluted by countervailing mentoring, institutional, or other environmental factors antagonistic to multidisciplinary approaches [2].
To supplement the recruitment of new cancer prevention researchers, some writing groups described a need to provide supplementary training in cancer prevention to professionals who are already established in their careers, a recommendation espoused in the IOM’s report, “Fulfilling the Potential for Cancer Prevention and Early Detection” [13]. Several state cancer plans include providing cancer prevention education for a variety of health-care providers [31]. However, the state cancer plans vary in support received, and the amount of state funding expended for strengthening the cancer prevention workforce and its impact are unknown. Funding is available for workshops that focus on “novel cancer-focused state-of-the-art research or methodological knowledge, or evidence-based cancer prevention and control interventions” through the NCI R25E award mechanism (PAR-12-049), although funds are not specifically targeted for health-care providers and would focus on them only if proposed to do so by sponsoring institutions. Awards are granted for up to 5-years at $300,000/year in direct costs and are not renewable, which may limit the long-term impact of cancer prevention training for providers if sponsors are unable to sustain developed programs after NCI funding ends. One cancer prevention education resource available to physicians for purchase was developed by the American Society for Clinical Oncology (ASCO): “Cancer Prevention Curriculum” book and CD ROM, and its maintenance module [32]; offering up to 28.5 h of CME credit, the book and CD cover a wide range of topics organized into 27 chapters, including tobacco, diet, screening, chemoprevention, community interventions, ethics of clinical trials, survivorship, and nine chapters about organ-specific cancers. At its annual meeting, ASCO has created a track to feature research and education in cancer prevention. Oncologists and primary care physicians alike recognize the need to deliver cancer prevention services to their patients [33] as together, they coordinate the long-term care for increasing numbers of cancer survivors and those at risk for cancer. However, even practicing oncologists report a need for more information and training to increase confidence in delivering cancer prevention and control care more effectively to their patients [20, 34]. Thus, the critical challenge then becomes how to reach ASCO members and beyond to other health-care providers, to provide training in cancer prevention to improve coordinated care, as well as how to pay for it [1].
Other Issues for Future Consideration
Critical issues remain for future consideration. For example, in the USA, educators currently struggle to attract students into research careers in general. Negative perceptions of features of science careers such as low salaries, long hours, little recognition, and high competition do little to draw interest. This problem is compounded by lack of awareness of careers opportunities in science, let alone for careers in cancer prevention. Also unknown is the impact of changing preferences in work expectations on recruiting and retaining the future cancer prevention workforce. Gen X, Millennials, and younger generations have different lifestyle and work priorities from their parents and earlier generations, such that new strategies are needed to accommodate generational differences. At the same time, the fierce competition for funding in the sciences demands ever increasing effort from researchers. It is not clear how these conflicting trends can be reconciled.
The academic health science centers environment in which research takes place, including for cancer prevention, is not appealing to many faculty, younger or older, and makes retention and reward additional challenges. Many, even established, faculty struggle to maintain productivity in the face of increasing administrative demands, while accommodating other professional and personal needs. Careers in academia are not widely perceived as enjoyable or worth the effort, and efforts to change the toxic environment are not on the horizon. NIH has made some important changes to allow more individuals to gain recognition for their work in the form of multiple PI-led grant awards, and journals recognize co-first authored articles. However, the ratio of tenure-track positions to those who aspire to them remains problematic. Generational culture change, decreases in funding levels, the paucity of secure faculty positions, and the explosive pace of scientific and technological advances have come together in a sort of perfect storm, dramatically increasing the volume of work to be done while decreasing the number of researchers available. Creative solutions to address these issues will be essential for building and retaining the future cancer prevention workforce.
One important moderator of the trend toward a decreasing workforce is the internationalization of scientific research. Thousands of scientists from around the world are coming to the USA for training and research (as well as working in their home countries) and making substantial contributions to cancer prevention research. The total number of foreign scientists and engineers working in academia in the USA has more than doubled in the past 35 years [35], and non-US citizens have constituted more than half of the US biosciences postdoctoral population since 2004 [36]. The influx of international scientists helps to mitigate decreases in the research workforce. At the same time, however, immigration restrictions, cultural and linguistic barriers in academia, and growth in some foreign economies, such as China’s, induce many of these researchers to return to their home countries. But given the projected increases of cancer incidence and mortality worldwide (27% and 45% according to WHO) [37], the need for cancer prevention efforts around the world will be of crucial importance, and cancer prevention efforts must be relevant to the types and causes of cancers found in various geographical regions, infrastructures and economic environments, and cultural landscapes. This is especially true of cancers that are preventable by behavior change, which will require specialized, culturally appropriate interventions. Thus, well-trained researchers in cancer prevention are needed around the world. Future efforts for the cancer prevention workforce must not neglect this critical topic.
The Need for a National Cancer Prevention Workforce Plan
Some gaps in the cancer prevention and control workforce have already been identified. For example, the National Cancer Registrar Association has reported anecdotal evidence for shortages in the professionals who manage and staff tumor registries that are critical for cancer surveillance. Feedback from a 2006 workforce survey indicated unfilled or difficult to fill registrar positions that vary by type of position and geographic region [38]. Other shortages are more difficult to quantify, but increasing job opportunities in cancer prevention have been reported [2]. To support health science training and education across the country, the NIH has used funding mechanisms that vary in scope and size. Some are broad and support a wide range of disciplines for professional training. Others are narrower in focus, in order to facilitate targeted recruitment of professional expertise within specific topics or disciplines. This system has prospered through free-market competition of institutions and individuals.
Benefits of using an open competition system to establish health science training and education are several. They include providing equal opportunity to compete for resources and the freedom to determine how best to address the workforce needs that they perceive, taking advantage of the unique strengths of their sponsoring institutions and leaders. Indeed, minimal requirements imposed by funding agencies allow programs to range in size and approach, maximizing the fit of training programs to particular research niches within the field. Many large health science centers have competed successfully for training program support, taking advantage of greater capacity and existing infrastructure.
Disadvantages to free competition exist as well. For example, unguided proliferation is likely to create a hodge-podge of programs that duplicates efforts and resources, leaving gaps unaddressed. As expanding training activities where programs or expertise already exist does not broaden the workforce where it is needed, funding agencies may be discouraged from supporting new training programs, whether they are of equal quality or better than existing ones. Also, training resources often go to large research centers that have other assets and advantages for sponsoring educational activities, but smaller centers may have greater need to develop expertise. The latter may not compete well, having disadvantages that are difficult to overcome without funding support that then becomes a self-perpetuating problem. This may help explain why several states in the Midwestern United States do not have NCI-designated comprehensive cancer centers or NCI-funded training programs, as gaps may occur either in topic or by geographic region, or both. Another disadvantage is the amount of time needed for training relative to the urgency of addressing shortages. While some professions can train large numbers of individuals quickly for positions that require less education and training [16], other professions that require more intensive preparation may not be able to mobilize sufficiently fast if needs are urgent. In general, the free-market competition of applicants to the NIH for training and education funds, while advantageous in some respects, is problematic in others. The disparities could be addressed by developing a national cancer prevention workforce plan.
Forming a National Cancer Prevention Workforce Plan
Three resources are needed to create and implement a national cancer prevention workforce plan: leadership, data, and commitment for sustained support in cancer prevention and control. Leadership is needed both to recognize the role that cancer prevention and control can play in reducing the burden of cancer and to champion the need to nurture and maintain a health workforce to sustain cancer prevention activities. Such leadership must facilitate identification of workforce needs in the field of cancer prevention and control and define the goals to address them. Leaders are also needed to ensure that sufficient resources are made available to sustain the workforce, to oversee implementation of needed changes and the evaluation of their impact, and to maintain as a priority developing and strengthening the workforce in cancer prevention and control. Leadership is needed from a variety of stakeholders, including research and clinical leaders in the field, funding agencies, and professional membership societies who have interest in developing their membership, as well as patient groups and communities who are direct consumers of cancer prevention services.
Another major building block in creating a national workforce plan is data about the cancer prevention workforce, both current workers and those in training. Metrics of the workforce would allow surveillance for emerging areas of need and prevention of workforce shortages. Without metrics for measuring and models for forecasting, it becomes impossible to determine whether the workforce will be sufficiently prepared to meet future needs in cancer prevention and control. Interviews with cancer center directors suggest that many centers may not track staffing metrics in ways that facilitate workforce monitoring [39]. Valuable information for evaluating training and education activities includes long-term career tracking of those who have received funding as well as those who did not. Such data may be available for trainees, current and former, who received funding from the NIH, but only to NIH staff. Ultimately, even the best plans are doomed if long-term commitment is not secured.
Ideally, a national cancer prevention workforce plan would include several elements. First, an inventory should be taken of existing training and educational resources in cancer prevention and control followed by a list of workforce gaps, either identified or shortly anticipated. The inventory and list would be organized by career stage and type of profession or discipline, and include topics and geographic areas for targeted resources. Next would be a plan for short-term management of the workforce, which would strengthen productive programs, reduce or eliminate unnecessary resources, and propose strategies to address shortages. A final section would describe long-term strategies for surveillance and evaluation of the workforce, anticipation of its needs, and prevention of shortages. For oversight and implementation of plans, roles for stakeholders would need to be specified—for individuals, professional societies, universities and professional schools, funding agencies, and systems at large that prepare and influence resources for developing the workforce. Preferably, efforts on behalf of the cancer prevention workforce would be performed in partnership with existing resources. For example, one of C-Change’s major initiatives is to engage the corporate sector in cancer prevention activities through employer-sponsored health plans [40]. The CEO-Roundtable on Cancer is another non-profit organization that uses an accreditation system to engage employers in sponsoring prevention activities [41]. In the end, whatever strategies are used should employ the best attributes of an open competition system, while also incorporating mechanisms to provide sufficient guidance to manage the workforce without being overly proscriptive or inflexible.
Risk of the Status Quo
The likelihood is good that the current system for sponsoring the training and education of the future workforce in cancer prevention will continue to serve, but perhaps only adequately so. NIH program officers and their advisors can use the tools they currently have available to shape training and education resources and minimize duplication of efforts; they can choose judiciously from among proposed programs winnowed through the peer-review process, and develop program announcements to direct interest to specific areas of need and interest. However, these are blunt tools for managing the workforce in cancer prevention effectively and the risk for failure is substantial when borne without the benefit of comprehensive surveillance data and guidance from regular feedback from those in the field. Existing gaps may continue to be unaddressed and new ones go unnoticed; when gaps are detected, the system may be sluggish in its response to meet workforce needs [16]. Mobilizing resources, recruiting individuals for training, and preparing them for careers in cancer prevention and control take time and effort, often years before professionals are ready to launch their careers. Thus, in the absence of a clearly articulated strategic plan that enjoys the endorsement of multiple stakeholders, our ability to train and prepare the workforce adequately to meet changing public health needs in cancer prevention and control remains in peril.
Summary
All indicators suggest that the need for efforts to prevent cancer will only increase. The numbers of individuals who can benefit from prevention services, including those already diagnosed with cancer or at risk for cancer, has grown over time. Regardless of the number or difficulty of the challenges, we should not allow ourselves to lapse into contentment with the current pace of preventing cancer. Given the amazing strides in the past 50 years against other major causes of death such as stroke, influenza, and cardiovascular disease, as well as those against HIV/AIDS in the past 30 years, progress against cancer and its prevention should be a major national and international goal. To achieve this goal, ensuring the health of the workforce in cancer prevention and control is imperative.
