Abstract:
In 2030, 60% of all new cancer diagnoses (15/25 million cases) and 80% of cancer related deaths (10/13 million deaths) will occur in low and middle income countries (LMICs) [1]. This explosion in cancer incidence is attributed to prolonged life expectancy in steadily growing populations with high levels of modifiable risk factors such as tobacco/alcohol and unhealthy diets. Despite the significant health burden, LMICs spend less than 10% of the global cancer budget. Cancer therapies are exponentially sprouting in rich countries but LMICs are not proportionally benefitting from this growth. Corruption, lack of infrastructure, poverty, and absence of national cancer policies/goals have hindered the development of quality cancer care programs. Radiotherapy has particularly suffered because of the perceived assumption that establishing quality radiotherapy centers in LMICs is unaffordable, non-sustainable and therefore unattainable and should not be pursued. Currently, up to 90% of LMIC inhabitants lack sufficient radiotherapy access and about 30 countries in Africa do not have a single treatment machine. It is estimated that by 2020, >9000 treatment machines, >10,000 radiation oncologists, and thousands of physicists and therapists are needed to treat patients in LMICs per evidence-based radiotherapy recommendations [2]. Recently, a group of experts with the Lancet Oncology Commission [3] reviewed the current radiotherapy capacity in LMICs and estimated the 20-year burden of cancer requiring radiotherapy and the needed investments to bring radiotherapy capacity in these countries to the needed levels. The published report provides compelling evidence that investment in radiotherapy not only will save millions of lives but will also bring significant economic benefits. The initial capital costs of scaling up radiotherapy may appear prohibitive, but these figures are based on estimations and projections that promise to deliver radiotherapy that is safe, timely, effective, efficient, equitable and patient centered. By aiming at quality care delivery, we can guarantee the highest returns on investments not only in oncologic outcomes but also in curbing loss in health-related productivity and life years. We hereby discuss few strategies to directly or indirectly reduce the capital or operating costs of such an expansion: - Trans-national, public and private partnerships: International organizations (such as the WHO, IAEA, etc) in collaboration with interested academic consultants and national governments should plan the required radiotherapy centers based on individualized national cancer priorities in the setting of a wide cancer care policy. This will require however a significant buy-in from national governments which are expected to establish effective social security systems with universal health coverage, create reliable cancer registries, implement effective cancer preventative and early diagnosis programs and finally promote outreach health literacy programs in real-world settings. Once international investments are coupled to national needs/efforts, minimal wasting of resources and maximal return on investment will be attained. - Centralization and pooling of resources regionally and internationally: This is a crucial step to at least jump start radiotherapy programs especially in the very low income countries where efforts are generally starting from nothing or close to nothing at best. High quality radiotherapy/simulation units donated by and refurbished in developed countries can provide a starting point around which other resources can be pooled. Regional centers can create circles of remote dosimetry/physics support and chart rounds via video conferencing to promote continued education and high quality treatment plans. These regional networks can be also connected to international cancer centers of excellence for further support and collaboration. Tax breaks could be offered to academic institutions or manufacturers in rich countries to participate in this process. - Investing in technology/science adapted to local needs in developing countries: Even if the capital is available, current manufacturing capabilities will not be able to build the required number of machines by 2020 as required. There is thus an immense need for innovative low cost, high quality radiotherapy units. Research and development departments should be offered incentives to create these tools. Optimizing the use of radiation techniques and per-unit activity to adapt to the treatment demands in developing countries will also improve benefit to cost ratio. - Hypofractionation: The number of “radiation fractions per year” is used as a surrogate for radiotherapy demand. Hypofractionation, thus, is a major strategy to optimize radiotherapy utilization and decrease operating costs without compromising outcomes in many cancer sites. For example, in the case of 1000 early breast [4] and 1000 early prostate cancer [5] patients requiring radiotherapy per year, using evidence-based hypofractionated treatments, not necessarily the extremely hypofractionated high-tech stereotactic radiation, would decrease the number of needed treatment machines from 10 to 6 and the number of therapists from 25 to 14. It will also decrease the duration of treatment per patient and thus allow more patients to be treated daily. Despite these benefits, hypofractionation remains widely underutilized even in developed countries [6]. Figure 1 - Investing in building local skills: Skilled radiation oncologists, therapists and physicists are very expensive commodities. While initial external support is crucial, new radiation centers need to eventually become self-sufficient and sustainable. Establishing local training programs should be a national priority in developing countries to decrease the cost of external training and limit brain drain. There is no magic wand to decrease the initial cost of investing in building radiotherapy capabilities but through careful planning and strong collaborations, millions of lives can be saved. Cost is crucial but we should not lose compass of our goal: delivering quality radiotherapy treatments to cure, improve the quality of life and alleviate pain in of millions of patients with cancer who are desperately in need.
