RESUMEN

Health-care systems in sub-Saharan Africa are considered to be new markets for pharmaceutical companies. This perception is particularly relevant within oncology, as the pharmaceutical industry has changed strategic priorities in the past 10 years to focus on cancer. Since the 1930s, pharmaceutical companies have used advertisements, sample drugs, gifts, paid speaking engagements, advisory boards, and trips to conferences to influence clinical practice and policy. A large amount of literature describes the commonness of these practices and their effects on the behaviour of doctors. However, these data come almost exclusively from high-income countries. Industry-doctor relationships are increasingly common in sub-Saharan Africa and other low-income and middle-income countries. Although there are undoubtedly risks of industry engagement in low-income and middle-income countries, many programmes with educational, research, and clinical value would not occur in these countries without industry support. Thus, what is known about these relationships in high-income countries will not necessarily apply in low-income and middle-income countries. There is a need for widespread discussion about industry-oncologist interactions across the African continent and context-specific data to understand the potential risks and benefits of these relationships.

RESUMEN

BACKGROUND: Oncology randomized controlled trials (RCTs) are increasingly global in scope. Whether authorship is equitably shared between investigators from high-income countries (HIC) and low-middle/upper-middle incomes countries (LMIC/UMIC) is not well described. The authors conducted this study to understand the allocation of authorship and patient enrollment across all oncology RCTs conducted globally. METHODS: A cross-sectional retrospective cohort study of phase 3 RCTs (published 2014-2017) that were led by investigators in HIC and recruited patients in LMIC/UMIC. FINDINGS: During 2014-2017, 694 oncology RCTs were published; 636 (92%) were led by investigators from HIC. Among these HIC-led trials, 186 (29%) enrolled patients in LMIC/UMIC. One-third (33%, 62 of 186) of RCTs had no authors from LMIC/UMIC. Forty percent (74 of 186) of RCTs reported patient enrollment by country; in 50% (37 of 74) of these trials, LMIC/UMIC contributed <15% of patients. The relationship between enrollment and authorship proportion is very strong and is comparable between LMIC/UMIC and HIC (Spearman's ρ LMIC/UMIC 0.824, p < .001; HIC 0.823, p < .001). Among the 74 trials that report country enrollment, 34% (25 of 74) have no authors from LMIC/UMIC. CONCLUSIONS: Among trials that enroll patients in HIC and LMIC/UMIC, authorship appears to be proportional to patient enrollment. This finding is limited by the fact that more than half of RCTs do not report enrollment by country. Moreover, there are important outliers as a significant proportion of RCTs had no authors from LMIC/UMIC despite enrolling patients in these countries. The findings in this study reflect a complex global RCT ecosystem that still underserves cancer control outside high-income settings.

RESUMEN

BACKGROUND: Cancer was the fifth leading cause of death in Sudan general hospitals in 2020, and its incidence is increasing. Medical students' cancer education is key in cancer control. Evaluating the current education is the first step in optimizing it. The aim of this study was to assess undergraduate oncology education in Sudan public medical schools as reflected by the graduates of the year 2021-2022. METHOD: This was a cross-sectional institution-based study. A validated online questionnaire was sent between 8 September and 11 November 2022 to graduates who were selected using a stratified random sampling technique from 17 Sudan public medical schools. The data were collected using Google Forms and analyzed using R software version 4.2.2 and Microsoft Excel 2022. RESULTS: A total of 707 graduates completed the questionnaire. They reported generally poor exposure to oncology. Palliative and radiation oncology in addition to chemotherapy daycare units were never attended by 76.0%, 72.0%, and 72.0% of graduates, respectively. The massed oncology curriculum was associated with increased hours of lectures dictated to medical (p = 0.005), radiation (p < 0.001), and palliative oncology (0.035). It was associated with an increased likelihood of assessment in breaking bad news (p < 0.001), counseling cancer patients (p = 0.015), and oncology-related knowledge (p < 0.001). The massed curriculum was associated with a decrease in interest in pursuing an oncology career (p = 0.037). Students were generally confident in their oncology competencies, and no difference was observed in relation to the curriculum approach (p > 0.05). CONCLUSION: This study reflected poor exposure to oncology at the undergraduate level in Sudanese public medical schools. The massed oncology curriculum was associated with formal assessment of oncology-related competencies and better exposure to some disciplines, such as radiation and palliative oncology. Nonetheless, it was associated with decreased interest in an oncology career. In spite of the poor exposure, graduates were confident in their skills in oncology-related competencies. Further objective analysis of competence is needed.

RESUMEN

With the advent of innovative therapeutics for and the rising costs of cancer management, low-income and middle-income countries face increasing challenges to deliver effective and sustainable health care. Understanding of how countries are selecting and prioritising essential cancer interventions is poor, including in the formulation of policies for essential medicines. We did an in-depth subanalysis from a global dataset of national cancer control plans (NCCPs), aiming to identify possible determinants of inclusion of policies related to essential medicines in the NCCP. The results showed poor global comprehensiveness of NCCPs, and substantial deficits in policies for financial hardships due to cancer care, specifically for access to cancer medicines. Specification of budget allocations, policy of protection from catastrophic health expenditure, and national treatment guidelines in the NCCPs contributed to more consistent policies on essential cancer medicines. The bedrock to deliver effective cancer programmes resides in the assurance of comprehensive, consistent, and coherent policy formulation, to orient resource selection and health investments, ultimately delivering equitable health for all.

RESUMEN

In sub-Saharan Africa (SSA), urgent action is needed to curb a growing crisis in cancer incidence and mortality. Without rapid interventions, data estimates show a major increase in cancer mortality from 520 348 in 2020 to about 1 million deaths per year by 2030. Here, we detail the state of cancer in SSA, recommend key actions on the basis of analysis, and highlight case studies and successful models that can be emulated, adapted, or improved across the region to reduce the growing cancer crises. Recommended actions begin with the need to develop or update national cancer control plans in each country. Plans must include childhood cancer plans, managing comorbidities such as HIV and malnutrition, a reliable and predictable supply of medication, and the provision of psychosocial, supportive, and palliative care. Plans should also engage traditional, complementary, and alternative medical practices employed by more than 80% of SSA populations and pathways to reduce missed diagnoses and late referrals. More substantial investment is needed in developing cancer registries and cancer diagnostics for core cancer tests. We show that investments in, and increased adoption of, some approaches used during the COVID-19 pandemic, such as hypofractionated radiotherapy and telehealth, can substantially increase access to cancer care in Africa, accelerate cancer prevention and control efforts, increase survival, and save billions of US dollars over the next decade. The involvement of African First Ladies in cancer prevention efforts represents one practical approach that should be amplified across SSA. Moreover, investments in workforce training are crucial to prevent millions of avoidable deaths by 2030. We present a framework that can be used to strategically plan cancer research enhancement in SSA, with investments in research that can produce a return on investment and help drive policy and effective collaborations. Expansion of universal health coverage to incorporate cancer into essential benefits packages is also vital. Implementation of the recommended actions in this Commission will be crucial for reducing the growing cancer crises in SSA and achieving political commitments to the UN Sustainable Development Goals to reduce premature mortality from non-communicable diseases by a third by 2030.

RESUMEN

As part of a university-wide initiative, competency-based medical education (CBME) was implemented in the Medical Oncology training program at Queen's University in July 2017. Stages, entrustable professional activities (EPAs), and required training experiences established by the Royal College of Physicians and Surgeons of Canada (RCPSC) national subspecialty committee were adopted. Entrada (Elentra), the electronic portfolio developed at Queen's University, was used for assessment collection. Between July 2017 and December 2018, participating faculty members completed 157 assessments. Eighty-nine percent were EPA assessments with a median of 16 assessments per faculty member (range 1-40). Ninety-five percent of assessments included written "Comments" or "Next steps" with 56% of all assessments including specific or actionable feedback. Discussions between the program director, residents, program administrator, CBME education consultant, and CBME lead led to the identification of 9 lessons learned during implementation. These centered on (1) faculty and resident development and engagement; (2) sharing the work of CBME; (3) collaboration and communication; (4) global assessment; (5) assessment plan challenges; (6) burden of CBME; (7) limitations of e-portfolio; (8) importance of early tracking of resident progress; and (9) culture change. This article describes the experience of the authors and considers strategies that may be helpful to programs implementing CBME in their teaching and learning environment.

RESUMEN

Cancer has not been an explicit priority of Canada's international health and development agenda, but it is key to realising the country's Sustainable Development Goal commitments. Multiple converging political, health, and social forces could now drive support for a more integrated Canadian approach to global cancer control. Success will depend on the extent to which Canadian leaders and institutions can build consensus as a community and agree to work together. Collaboration should include agreement on the framing and prioritisation of the core issues, building a broad coalition base, aligning with priorities of international partners, and on a governance structure that reflects the principles of equity, diversity, and inclusion. This Series paper will discuss global cancer control within Canada's global health agenda, how Canada can address its history of colonisation and present-day disparities in its global work, and the challenges and opportunities of creating a Canadian global cancer control network.

RESUMEN

We adopt a holistic-micro, meso, macro-approach to health leadership ethics to examine how low- and middle-income countries have responded to the COVID-19 pandemic. Healthcare delivery happens within complex settings in low- and middle-income countries and high-income countries. These settings are riddled with systemic political and economic challenges which, in some instances, make it difficult for health leaders to be ethical. These challenges, however, are not unique to low- and middle-income countries. Globally, countries can learn from ethical health leadership missteps that occurred during low- and middle-income countries' responses to COVID-19. We discuss the implications of problematic ethics in health leadership on managing pandemics in low- and middle-income countries, using Zimbabwe as an example. We offer suggestions on what can be done to improve ethical health leadership in response to future health crises in both high-income and low- and middle-income nations.

RESUMEN

The post-graduate medical programs at Queen's University transitioned to a competency-based medical education framework on July 1, 2017. In advance of this transition, the Medical Oncology program participated in a pilot of six Entrustable Professional Activities (EPAs) focused workplace-based assessment (WBA) tools with faculty and residents. The purpose of this sequential explanatory mixed method study was to determine the extent to which these WBAs provided quality feedback for residents. The WBAs were introduced into daily clinical practice and, once completed, were collected by the research team. A resident focus group (n = 4) and faculty interviews (n = 5) were also conducted. Focus group and interview data were analyzed using an emergent thematic analysis. Data from the completed assessment tools were analyzed using both descriptive statistics and a literature-informed framework developed to assess the quality of feedback. Six main findings emerged: Verbal feedback is preferred over written; providing both written and verbal feedback is important; effective feedback was seen as timely, specific, and actionable; the process was conceptualized as coaching rather than high stakes; there were logistical concerns about the WBAs, and additional clarification about the WBA tools is needed. This study provides insight into faculty and resident perceptions of quality feedback and the potential for WBA tools to assist in providing effective feedback to residents as we shift to competency-based medical education in Canada. Our results suggest the need for additional faculty development around the use of the tools, and their intended role, and the elements of quality feedback.

RESUMEN

The purpose of this study is to understand the perspectives of African Oncologists on the role of accreditation and on global standards. We developed a survey that addressed African oncologists' opinions on the role of accreditation. The survey also included 187 standards from World Federation of Medical Education Postgraduate medical education (PGME) standards, American Council of Graduate Medical Education (ACGME)-I standards for hematology/oncology, and the Royal College of Physician and Surgeons of Canada Medical Oncology standards. A 3-point scale was employed for each standard: 1 = not important, 2 = important but not essential, 3 = essential. The survey was sent to 79 physicians, 38 responded. Eighty-seven percent agreed that accreditation ensures quality. Forty-five percent agreed it will not increase migration of qualified doctors. Twenty-two individuals who completed the entire survey were analyzed for the standards. Five standards received the highest ratings of 3 (essential) from all respondents. One standard received a rating of < 2.0. The majority of standards had ratings between 2.6 and 2.94 indicating African oncologists found most standards to be useful. Ratings < 2.6 were mostly related to resource constraints. Most African Oncologists believed that accreditation ensures quality of education, and most standards were considered important. This data is useful for developing and adapting accreditation standards in resource-constrained settings.

RESUMEN

A critical shortage of trained cancer specialists is one of the major challenges in addressing the increasing cancer burden in low- and middle-income countries. Inadequate undergraduate cancer education in oncology remains a major obstacle for both task shifting to general practitioners and for training of specialists. We provide the first report of cancer education in Rwanda's undergraduate program to survey how new graduates are prepared to provide care for cancer patients. Anonymous online survey was sent January to June 2017 to medical students in their senior clinical years (years 5 and 6). Questions related to the demographics, medical curriculum, and general oncology exposure were included in the survey. Of 192 eligible students, 42% (n = 80) completed the survey and were analyzed. The majority were 25 to 29 years of age and 41% were female. Internal medicine was cited to provide the most exposure to cancer patients (50%) and cancer bedside teaching (55%). Close to a half (46%) have been taught oncology formally in addition to bedside teaching. A tenth (11%) of the participants felt comfortable in attending a cancer patient, and a fifth (21%) of the students felt comfortable while addressing multimodality treatment approach. The majority (99%) of the participants preferred having a formal oncology rotation. Of particular interest, 61% of the students are interested in pursuing an oncology career path. There is a need to modify the current oncology undergraduate curriculum to prepare future physicians for delivering cancer care in Rwanda. Raising the profile of oncology in undergraduate medical education will complement the on-going efforts to increase the country's capacity in task shifting and in training of cancer specialists.

RESUMEN

Sudan has been under an armed conflict between the Sudanese Armed Forces and the Rapid Support Forces (RSF) militia since April 15, 2023. The conflict has turned the country into the largest internal displacement humanitarian crisis with 9.05 million internally displaced persons including 2.2 million children younger than 5 years and caused 1.47 million Sudanese to flee the country as refugees. The conflict has had a major destructive impact on the health system, which has incurred targeting with air raids, ground invasion, vandalization, looting of assets and supplies, and killing of doctors, nurses, and other health personnel. Khartoum Oncology Hospital, Sudan's main cancer hub for treatment, diagnostics, and research has become nonfunctional as a result of the conflict. The National Cancer Institute in Wad Medani, the second largest hub, faced a similar fate as the conflict spread to Al-Gezira State. Patients with cancer have been displaced multiple times in Sudan with grave consequences on the continuity of care, worsening of their disease outcomes and palpable negative impacts on children. The oncology workforce in Sudan have themselves been displaced yet are working hard to provide services and care for patients under impossible circumstances. Sudan's doctors in diaspora have rallied to provide support but they face multiple obstacles. As the conflict continues to spread, we call upon the WHO, the United Nations Children's Fund, St Jude Hospital, and all relevant partners to implement an immediate evacuation operation with urgent air lifts of the affected children to continue their cancer care in neighboring countries as was done in Ukraine and Gaza.

RESUMEN

PURPOSE: Conflicts of interest (COIs) between oncologists and industry might considerably influence how the presentation of the research results is delivered, ultimately affecting clinical decisions and policy-making. Although there are many regulations on reporting COI in high-income countries (HICs), little is known about their reporting in low- and middle-income countries (LMICs). Oncology Transparency Under Scrutiny and Tracking (ONCOTRUST-1) is a pilot global survey to explore the knowledge and perceptions of oncologists regarding COI. MATERIALS AND METHODS: We designed an online 27-question-based survey in the English language to explore the perceptions and knowledge of oncologists regarding COI, with an emphasis on LMICs. Descriptive statistics and the Consensus-Based Checklist for Reporting of Survey Studies guidelines were used to report the findings. RESULTS: ONCOTRUST-1 surveyed 200 oncologists, 70.9% of them practicing in LMICs. Median age of the respondents was 36 (range, 26-84) years; 47.5% of them were women. Of the respondents, 40.5% reported weekly visits by pharmaceutical representatives to their institutions. Regarding oncologists' perceptions of COI that require disclosure, direct financial benefits, such as honoraria, ranked highest (58.5%), followed by gifts from pharmaceutical representatives (50%) and travel grants for attending conferences (44.5%). By contrast, personal or institutional research funding, sample drugs, consulting or advisory board, expert testimony, and food and beverage funded by pharmaceutical industry were less frequently considered as COI. Moreover, only 24% of surveyed oncologists could correctly categorize all situations representing a COI. CONCLUSION: These findings underscore the importance of clear guidelines, education, and transparency in reporting COI in oncology. This hypothesis-generating pilot survey provided the rationale for ONCOTRUST-2 study, which will compare perceptions of COI among oncologists in LMICs and HICs.

RESUMEN

PURPOSE: Open-access publishing expanded opportunities to give visibility to research results but was accompanied by the proliferation of predatory journals (PJos) that offer expedited publishing but potentially compromise the integrity of research and peer review. To our knowledge, to date, there is no comprehensive global study on the impact of PJos in the field of oncology. MATERIALS AND METHODS: A 29 question-based cross-sectional survey was developed to explore knowledge and practices of predatory publishing and analyzed using descriptive statistics and binary logistic regression. RESULTS: Four hundred and twenty-six complete responses to the survey were reported. Almost half of the responders reported feeling pressure to publish from supervisors, institutions, and funding and regulatory agencies. The majority of authors were contacted by PJos through email solicitations (67.8%), with fewer using social networks (31%). In total, 13.4% of the responders confirmed past publications on PJo, convinced by fast editorial decision time, low article-processing charges, limited peer review, and for the promise of academic boost in short time. Over half of the participants were not aware of PJo detection tools. We developed a multivariable model to understand the determinants to publish in PJos, showing a significant correlation of practicing oncology in low- and middle-income countries (LMICs) and predatory publishing (odds ratio [OR], 2.02 [95% CI, 1.01 to 4.03]; P = .04). Having previous experience in academic publishing was not protective (OR, 3.81 [95% CI, 1.06 to 13.62]; P = .03). Suggestions for interventions included educational workshops, increasing awareness through social networks, enhanced research funding in LMICs, surveillance by supervisors, and implementation of institutional actions against responsible parties. CONCLUSION: The prevalence of predatory publishing poses an alarming problem in the field of oncology, globally. Our survey identified actionable risk factors that may contribute to vulnerability to PJos and inform guidance to enhance research capacity broadly.

RESUMEN

BACKGROUND: Carbohydrate antigen 19-9 (CA19-9) is a widely used biomarker in pancreatic cancer. There is no consensus on the interpretation of the change in CA19-9 serum levels and its role in the clinical management of patients with pancreatic cancer. METHODS: Individual patient data from 6 prospective trials evaluating gemcitabine-containing regimens from 3 different institutions were pooled. CA19-9 values were obtained at baseline and after successive cycles of treatment. The objective of this study was to correlate a decline in CA19-9 with outcomes while undergoing treatment. RESULTS: A total of 212 patients with locally advanced (n = 50) or metastatic (n = 162) adenocarcinoma of the pancreas were included. Median baseline CA19-9 level was 1077 ng/mL (range, 15-492,241 ng/mL). Groups were divided into those levels below (low) or above (high) the median. Median overall survival (mOS) was 8.7 versus 5.2 months (P = .0018) and median time to progression (mTTP) was 5.8 versus 3.7 months (P = .082) in the low versus high groups, respectively. After 2 cycles of chemotherapy, up to a 5% increase versus ≥ 5% increase in CA19-9 levels conferred an improved mOS (10.3 vs 5.1 months, P = .0022) and mTTP (7.5 vs 3.5 months, P = 0.0005). CONCLUSIONS: In patients who have advanced pancreatic cancer treated with gemcitabine-containing regimens baseline CA19-9 is prognostic for outcome. A decline in CA19-9 after the second cycle of chemotherapy is not predictive of improved mOS or mTTP; thus, CA19-9 decline is not a useful surrogate endpoint in clinical trials. Clinically, a ≥ 5% rise in CA19-9 after 2 cycles of chemotherapy serves as a negative predictive marker.
