Abstract
International research and collaboration has been a part of the National Cancer Institute's (NCI) mission since its creation in 1937. Early on, efforts were limited to international exchange of information to ensure that U.S. cancer patients could benefit from advances in other countries. As NCI's research grant portfolio grew in the 1950s, it included a modest number of grants to foreign institutions, primarily in the U.K. and Europe. In the 1960s, the development of geographic pathology, which aimed to study cancer etiology through variations in cancer incidence and risk factors, led to an increase in NCI funded international research, including research in low- and middle-income countries. In this paper, we review key international research programs, focusing particularly on the first fifty years of NCI history. The first NCI-led overseas research programs, established in the 1960s in Ghana and Uganda, generated influential research but also struggled with logistical challenges and political instability. The 1971 National Cancer Act was followed by the creation of a number of bilateral agreements with foreign governments, including China, Japan, and Russia, to support cooperation in technology and medicine. While these agreements were broad without specific scientific goals, they provided an important mechanism for sustained collaborations in specific areas. With the creation of the NCI Center for Global Health in 2011, NCI's global cancer research efforts gained sustained focus. While the global cancer burden has evolved over time, increasingly impacting low- and middle-income countries, NCI's role in global cancer research remains more important than ever.

Abstract
PURPOSE Burkitt lymphoma (BL) accounts for 90% of pediatric lymphomas in sub-Saharan Africa. Plasmodium falciparum (Pf) malaria is considered an etiological factor of BL. We describe the geographic distribution of pediatric BL in Malawi and association with malaria prevalence (PfPR). We also examine the influence of travel time to cancer referral center as a potential confounder. METHODS We enrolled pathologically confirmed incident pediatric BL cases (2013-2018) into a prospective observational cohort at Kamuzu Central Hospital (KCH) in Lilongwe, the main tertiary cancer referral center serving central and northern Malawi. District of residence was recorded for all participants. We calculated district-level average annual BL incidence rate (BLIR) using census population estimates. PfPR was extracted from the National Malaria Control Program 2010 report. BLIR and PfPR maps were constructed in QGIS. Moran's I was used to identify BL spatial clusters. Travel time to KCH was modeled in AccessMod. Pearson's correlation and multivariate regression was used to statistically examine the relationship between PfPR, travel time to KCH and BL. RESULTS Of 220 participants, 69 (31%) resided in Lilongwe. BLIR was higher in central region districts (0.86 cases per 100,000) than northern districts (0.32 cases per 100,000). BLIR was elevated in lakeshore districts. Districts with elevated PfPR tended to have elevated BLIR. A low-risk BL cluster was detected in the northern region. BLIR was lower in districts where travel time to KCH exceeded 4 hours, particularly the north. Statistically, BLIR was positively correlated with PfPR ( r = 0.77, P < .01) and negatively correlated with travel time to KCH ( r = –0.67, P < .01). A 1% increase in PfPR predicted an increase in BLIR of 0.02 cases per 100,000 ( P = .03) when controlling for travel time to KCH. CONCLUSION Our study supports evidence for an association between Pf and BL. Additionally, our results may indicate a need to improve geographic accessibility to tertiary cancer services in Malawi's northern region.

Abstract
PURPOSE The objective of this study is to document the prevalence of traditional, complementary, and alternative medicine (TCAM) use by adult cancer patients at a national teaching hospital in Malawi. We aim to document the products/therapies used, the reason for use, as well as patient-reported satisfaction with TCAM practitioners and modalities. METHODS We conducted investigator-administered interviews with adult cancer patients presenting to the Kamuzu Central Hospital (KCH) Cancer Clinic in Lilongwe, Malawi between January and July 2018. The KCH is a national teaching hospital in the capital of Lilongwe, which serves patients with cancer from the northern half of Malawi. Descriptive statistics were used to describe TCAM use and logistic regression was applied to identify predictors of TCAM. RESULTS A total of 263 participants completed the survey, of which 70% (n = 183) were female and average age was 45 (SD 14) years old. The prevalence of overall TCAM use was 84% (n = 222), and 60% (n = 157) of participants reported combining TCAM with conventional cancer treatment. The majority of patients used TCAM to directly treat their cancer versus for symptom management. Patients reported using faith-based healing (64%, n = 168), herbal medicine (56%, n = 148), diet change (46%, n = 120), and vitamins/minerals (23%, n = 61). Participants reported the highest satisfaction for physicians among practitioners and diet change for modalities. Female gender was found to be a predictor of TCAM with conventional treatment use, no other significant predictors were observed. CONCLUSION There is a high prevalence of TCAM use among an adult population with cancer in Malawi, and a wide variety in the TCAM modalities used among patients. Additional studies are needed to identify risks and benefits of TCAM use to assist with policy and public health, patient safety, and holistically address the global burden of cancer.

Abstract
Conducting clinical research in low- and middle-income countries is essential to address the global impact of cancer. In 2017, ASCO convened an Academic Global Oncology Task Force that recommended an increase in global oncology research to enhance the field of oncology through research and education. The emerging crisis of cancer in Africa demands a similar global commitment to workforce development, infrastructure building, and access to care that will provide a platform for impactful and relevant research efforts. In the words of the African Organisation for Research and Training in Cancer, it is time to "transform cancer control in Africa through collaboration in education, research, (and) delivery of equitable and timely interventions to minimize the impact of cancer." Although there are some initiatives aimed at developing research capacity to host trials in Africa, there is now a need to establish strategic partnerships with the aim of achieving harmonized, accredited clinical trial units capable of running trials according to Good Clinical Practice standards.

Abstract
Cancer research currently is heavily skewed toward high-income countries (HICs), with little research conducted in, and relevant to, the problems of low- and middle-income countries (LMICs). This regional discordance in cancer knowledge generation and application needs to be rebalanced. Several gaps in the research enterprise of LMICs need to be addressed to promote regionally relevant research, and radical rethinking is needed to address the burning issues in cancer care in these regions. We identified five top priorities in cancer research in LMICs based on current and projected needs: reducing the burden of patients with advanced disease; improving access and affordability, and outcomes of cancer treatment; value-based care and health economics; quality improvement and implementation research; and leveraging technology to improve cancer control. LMICs have an excellent opportunity to address important questions in cancer research that could impact cancer control globally. Success will require collaboration and commitment from governments, policy makers, funding agencies, health care organizations and leaders, researchers and the public.

Contemp Clin Trials Commun 2022; 26:100903.

Abstract
Cervical cancer is the leading cause of cancer mortality among Malawian women, despite being preventable through screening and preventive therapy. In 2004, Malawi implemented a national screening program, using visual inspection with acetic acid (VIA) and cryotherapy, but its success has been limited due to equipment and human resources challenges. Since the development of that program, new technologies for screening and treatment that are less resource-intensive and more scalable have become available. GeneXpert systems provide fast, accurate HPV results and are increasingly available in low-income countries. Self-collection for human papillomavirus (HPV) testing is a validated method for screening and improves uptake. Thermal ablation provides an alternative ablative treatment that is simpler to use than cryotherapy and can be performed with portable devices. Meanwhile, urine HPV testing methods provide promising options for primary screening. We designed a single-arm prospective study to investigate a novel HPV screen-triage-treat strategy among 1250 women in Lilongwe, Malawi. Our proposed strategy consists of (1) Xpert HPV testing of self-collected samples, (2) VIA and colposcopy for HPV-positive women, and (3) thermal ablation for HPV-positive/ablation-eligible women. We will collect cervical biopsies, Pap smears, and endocervical samples to validate the HPV results and VIA/colposcopy findings against endpoints of high-grade cervical intraepithelial neoplasia or cancer (CIN2+). We will evaluate same-day completion of our algorithm, its performance in triaging women for treatment, and 24-week treatment efficacy of thermal ablation. We will also explore the performance of HPV and methylation tests in urine samples, as compared to provider- and self-collected cervicovaginal samples.

Abstract
PURPOSE Low health literacy is a leading cause of treatment abandonment among patients receiving cancer care at Kamuzu Central Hospital (KCH) in Malawi. METHODS We developed cancer educational videos featuring Malawian providers and played them in the KCH oncology clinic. The videos addressed cancer-related topics, including disease biology, common myths, diagnostic procedures, treatment, side effects, and survivorship. After 6 months of implementation, we compared results from 50 pre- and postintervention surveys to assess change in cancer knowledge and care experience. RESULTS Both pre- and postintervention cancer knowledge were good: a median of nine questions were answered correctly of 11 in both assessments. Despite the intervention, most continued to incorrectly identify cancer as an infection (pre: n = 26, 52%; post: n = 25, 50%; P = 1.0), although improvements were observed in patients' knowledge of correct actions for fever at home (pre: n = 38, 76%; post: n = 43, 86%; P = .31). Care experiences were overall good. Postintervention results indicate that more patients felt always listened to by their providers (pre: n = 18, 36%; post: n = 29, 58%; P < .01). However, we also noted a higher rate of patient dissatisfaction of care as more patients felt that they could not understand chemotherapy counseling (pre: n = 11, 22%; post: n = 22, 44%; P < .01). Assessments of video satisfaction indicate that patients found the videos very helpful in terms of understanding their disease (n = 47, 96%) and side effects (n = 48, 98%) and felt empowered to speak up with their providers (n = 46, 96%). CONCLUSION Standardized education materials for patients that can be feasibly implemented throughout sub-Saharan Africa are urgently needed. Cancer educational videos are a low-cost way to educate and empower patients with cancer in resource-constrained settings although in-person discussions remain a crucial part of care.

Abstract
Objectives Invasive cervical cancer (ICC) is the leading cause of cancer-related death among women in Malawi. Barriers to screening for ICC in Malawi, such as long distances to health facilities and lack of public education about ICC, have hindered participation of women in ICC prevention programs. Given the burden of disease and barriers to screening, we implemented a community-based ICC screen-and-treat pilot study and present its successes and challenges. Study design This study was a screen-and-treat pilot study using Visual Inspection with Acetic acid (VIA) for screening and same-day thermal ablation for treatment of pre-cancerous lesions. The pilot was implemented in four rural community settings in Lilongwe District, Malawi. Methods With consultation from local leaders, as well as the UNC Project-Malawi Community Department and the Community Advisory Board, a team of researchers designed a rural, community-based ICC screen-and-treat pilot study. Over a 5-week period, we travelled to four rural communities to provide information about and screening for ICC and HIV through our study. The four selected rural locations were about an hour drive from Lilongwe City, Malawi. Detailed field notes were taken by study staff and then later analyzed and categorized as either strengths or challenges. Results Successes included support from local leaders, high uptake of screening (408 women underwent VIA, representing 88% of eligible women), positive experiences during screening, and good communication between study staff and participants. This communication enabled us to quickly address misperceptions about the study intent and procedures and to better understand some of the barriers to care. Challenges included insufficient medication for diagnosed sexually transmitted infections, finding ways to engage interested women who were ineligible due to young age, and not screening interested women because they needed male partner approval. Conclusion Community-based screen-and-treat programs with thermal ablation for ICC can be an effective way to engage hard-to-reach women in ICC preventive care. Our findings support existing literature which suggests that involvement of local leadership, women from the community, and their male partners, as well as ongoing peer education, may facilitate greater participation in ICC screening and treatment. In addition, we found ongoing communication between study staff and participants to be mutually beneficial. Finally, we suggest that future interventions consider bundling sexually transmitted infection treatment into ICC preventive care when engaging hard-to-reach populations.

Abstract
Abstract
Background
Atherectomy (AT) using an orbital/rotational system is useful in altering calcified plaque thereby facilitating stent placement and optimal stent expansion. Patients with diabetes mellitus (DM) are known to have a higher rate of complications after percutaneous coronary intervention. We aimed to assess the incidence of major adverse cardiovascular events after atherectomy in the diabetic population using a nationwide inpatient sample (NIS).
Methods
NIS-HCUP database from 2015–2017 was used to identify patients who underwent atherectomy. A cohort of patients with and without diabetes was identified. Demographics, in-hospital outcomes, complications in both groups were compared. Statistical significance was assigned at p<0.05.
Results
Out of 6184 patients who underwent AT, 3134 (50.6%) patients had DM. Baseline characteristics have been outlined in the table below. Complications were comparable between the two groups except for higher incidence of post-procedure VTE in Diabetic patients. In-hospital mortality was lower among patients with DM (2.24% vs 3.29%, p-0.27), while the mean length of stay (5.92 vs 4.91 days, p-0.002) and the hospitalization charges ($165118.4 vs 151226, p-0.04) were higher, but this difference in length of stay and hospitalization charges were nullified on multivariate regression.
Conclusion
Our study suggests that an AT for severely calcified plaque in the coronary artery is a safe option in patients with DM with comparable in-hospital complications and outcomes to non-DM patients.

Abstract
BACKGROUND Patient-reportedoutcomes (PROs) that assess health-related quality of life (HRQoL) are increasingly important components of cancer care and research that are infrequently used in sub-Saharan Africa (SSA). METHODS We administered the Chichewa Pediatric Patient-Reported Outcome Measurement Information System Pediatric (PROMIS)-25 at diagnosis, active treatment, and follow-up among pediatric lymphoma patients in Lilongwe, Malawi. Mean scores were calculated for the six PROMIS-25 HRQoL domains (Mobility, Anxiety, Depressive Symptoms, Fatigue, Peer Relationships, Pain Interference). Differences in HRQoL throughout treatment were compared using the minimally important difference (MID) and an ANOVA analysis. Kaplan-Meier survival estimates and Cox hazard ratios for mortality are reported. RESULTS Seventy-five children completed PROMIS-25 surveys at diagnosis, 35 (47%) during active treatment, and 24 (32%) at follow-up. The majority of patients died (n = 37, 49%) or were lost to follow-up (n = 6, 8%). Most (n = 51, 68%) were male, median age was 10 (interquartile range [IQR] 8-12), 48/73 (66%) presented with advanced stage III/IV, 61 (81%) were diagnosed with Burkitt lymphoma and 14 (19%) Hodgkin lymphoma. At diagnosis, HRQoL was poor across all domains, except for Peer Relationships. Improvements in HRQoL during active treatment and follow-up exceeded the MID. On exploratory analysis, fair-poor PROMIS Mobility <40 and severe Pain Intensity = 10 at diagnosis were associated with increased mortality risk and worse survival, but were not statistically significant. CONCLUSIONS Pediatric lymphoma patients in Malawi present with poor HRQoL that improves throughout treatment and survivorship. Baseline PROMIS scores may provide important prognostic information. PROs offer an opportunity to include patient voices and prioritize holistic patient-centered care in low-resource settings.

Abstract
BACKGROUND Cost-effectiveness data for cancer treatment are needed from sub-Saharan Africa, where diffuse large B-cell lymphoma (DLBCL) is a common, curable cancer. In high-income countries, the standard of care for DLBCL is R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) chemoimmunotherapy. Rituximab is often not available in sub-Saharan Africa due to perceived unaffordability, and treatment with CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) is common. We aimed to evaluate the cost-effectiveness of treatment in Malawi, comparing best supportive care, CHOP, or R-CHOP in patients with DLBCL. METHODS For this cost-effectiveness analysis, we used published Malawi microcosting data, clinical data from a prospective cohort treated with CHOP, and clinical trial data evaluating R-CHOP. We used a decision-tree model to calculate costs per disability-adjusted life-year (DALY) averted from the health system perspective for the treatment of patients with DLBCL with best supportive care, CHOP, or R-CHOP, running the model on a per-patient basis and a Malawi population-level basis. We used the WHO definitions of cost-effective (three times the GDP per capita of the country) and extremely cost-effective (equal to the GDP per capita of the country) as willingness-to-pay thresholds for Malawi. FINDINGS On a per-patient level, compared with best supportive care, CHOP was estimated to avert a mean 7·4 DALYs at an incremental cost of US$1384, for an incremental cost-effectiveness ratio (ICER) of $189 per DALY averted, which is substantially lower than the willingness-to-pay threshold (extremely cost-effective). Compared with CHOP, R-CHOP was estimated to avert 2·8 DALYs at an incremental cost of $3324, resulting in an ICER of $1204 per DALY averted, which is slightly higher than the cost-effective willingness-to-pay threshold. In probabilistic sensitivity analyses, CHOP remained cost-effective for DLBCL treatment in more than 99% of simulations, whereas R-CHOP was lower than the threshold in 46% of simulations. INTERPRETATION We estimated CHOP to be cost-effective for DLBCL treatment in Malawi, and that the addition of rituximab might be cost-effective. Despite upfront costs, DLBCL treatment is probably a prudent investment relative to other accepted health interventions in sub-Saharan Africa. FUNDING National Institutes of Health.

Abstract
Low-income and middle-income countries (LMICs) have a disproportionately high burden of cancer and cancer mortality. The unique barriers to optimum cancer care in these regions necessitate context-specific research. The conduct of research in LMICs has several challenges, not least of which is a paucity of formal training in research methods. Building capacity by training early career researchers is essential to improve research output and cancer outcomes in LMICs. The International Collaboration for Research methods Development in Oncology (CReDO) workshop is an initiative by the Tata Memorial Centre and the National Cancer Grid of India to address gaps in research training and increase capacity in oncology research. Since 2015, there have been five CReDO workshops, which have trained more than 250 oncologists from India and other countries in clinical research methods and protocol development. Participants from all oncology and allied fields were represented at these workshops. Protocols developed included clinical trials, comparative effectiveness studies, health services research, and observational studies, and many of these protocols were particularly relevant to cancer management in LMICs. A follow-up of these participants in 2020 elicited an 88% response rate and showed that 42% of participants had made progress with their CReDO protocols, and 73% had initiated other research protocols and published papers. In this Policy Review, we describe the challenges to research in LMICs, as well as the evolution, structure, and impact of CReDO and other similar workshops on global oncology research.

Abstract
The purpose of this article is to describe lessons from the first lymphoma clinical trial conducted by the AIDS Malignancy Consortium (AMC) in sub-Saharan Africa (SSA). AMC-068 was a randomized phase II comparison of intravenous versus oral chemotherapy for HIV-positive diffuse large B-cell lymphoma. Opening in 2016, AMC-068 planned to enroll 90 patients (45 per arm) in Kenya, Malawi, Uganda, and Zimbabwe over 24 months and follow patients for 24 months to assess overall survival. In 2018, the study closed after screening 42 patients but enrolling only 7. Challenges occurred during protocol development, pre-activation, and postactivation. During protocol development (2011-2012), major obstacles were limited baseline data to inform study design; lack of consensus among investigators and approving bodies regarding appropriateness of the oral regimen and need for randomized comparison with cyclophosphamide, doxorubicin, vincristine, and prednisone; and heterogeneity across sites in local standards for diagnosis, staging, and treatment. During pre-activation (2012-2016), challenges included unexpected length and layers of regulatory approval across multiple countries, need to upgrade pathology capacity at sites, need to augment existing chemotherapy infusion capacity at sites, and procurement issues for drugs and supplies. Finally, during postactivation (2016-2018), challenges included long delays between symptom onset and screening entry for many patients, leading to compromised performance status and organ function; other patient characteristics that frequently led to exclusion, including high tumor proliferative index or other pathologic features that were disallowed; and costs of routine diagnostic procedures often being borne by patients, which also contributed to pre-enrollment delays. Lessons from AMC-068 are being applied to the design and conduct of new AMC lymphoma trials in SSA, and the study has contributed to a strong operational foundation that will support innovative clinical trials in the future.

Abstract
BACKGROUND There are no clinical trials involving patients with diffuse large B-cell lymphoma (DLBCL) in sub-Saharan Africa since antiretroviral therapy (ART) for HIV became widely available in this region. We aimed to establish the safety and efficacy of rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) in patients with DLBCL in Malawi. METHODS This prospective, single-arm, non-randomised phase 1/2 clinical trial was done at Kamuzu Central Hospital Cancer Clinic (Lilongwe, Malawi). Eligible patients were adults (aged 18-60 years) with newly diagnosed DLBCL, an Eastern Cooperative Oncology Group performance status of 0-2, a CD4 count of 100 cells per μL or higher (if HIV-positive), measurable disease by physical examination, an absolute neutrophil count of 1000 × 109 cells per L or higher, a platelet count of 100 × 109 platelets per L or higher, a serum creatinine concentration of 132·60 μmol/L or less, a total bilirubin concentration of 34·21 μmol/L or less, a negative urine pregnancy test in women of childbearing potential, and no previous cytotoxic therapy. Pregnant or breastfeeding women, and individuals with CNS involvement from DLBCL, chronic hepatitis B infection (unless they were receiving tenofovir plus lamivudine), or any other comorbidities that would compromise the protocol objectives were excluded. Eligible patients received intravenous rituximab 375 mg/m2, cyclophosphamide 750 mg/m2, doxorubicin 50 mg/m2, and vincristine 1·4 mg/m2 (maximum 2 mg/m2), and oral prednisone 100 mg or an equivalent drug every 21 days for up to six cycles. HIV-positive patients received concurrent ART. The primary outcome was the proportion of patients with National Cancer Institute Common Terminology Criteria for Adverse Events grade 3 or 4 non-haematological toxic effects or treatment-related deaths after six cycles of treatment. Secondary efficacy outcomes included the proportion of patients with a complete response after six cycles of treatment, and progression-free survival and overall survival at 12 months and 24 months. This trial is registered with ClinicalTrials.gov, NCT02660710. FINDINGS Between Aug 1, 2016, and July 31, 2019, 76 patients were screened, of whom 37 were eligible for the study and received R-CHOP. The median age of patients was 44 years (IQR 39-49) and 16 (43%) were women. Of all 37 patients, 20 (54%) had stage III or IV DLBCL, and the age-adjusted international prognostic index was 2 or higher in 25 (68%) patients. 27 (73%) patients were HIV-positive, with a median CD4 count of 208 cells per μL (IQR 144-422), and 21 (78%) patients were receiving ART at enrolment. Patients completed a median of six cycles (IQR 4-6). Grade 3 or 4 non-haematological toxic effects were reported in 12 (32% [95% CI 19-49]) patients, the most common of which was infection (nine [24%] patients). Of 16 (43%) deaths, ten were due to progression of DLBCL, four were due to treatment-related complications, and two were due to other causes, yielding a treatment-related mortality of 11% (95% CI 4-26%). Grade 3 or 4 neutropenia was observed in 26 (70%) patients, and grade 3 or 4 anaemia was observed in 11 (29%) patients. A total of 22 (59%) patients had a complete response. Overall survival was 68% (95% CI 50-80) at 12 months and 55% (37-70) at 24 months, and progression-free survival was 59% (42-73) at 12 months and 53% (35-68) at 24 months. INTERPRETATION R-CHOP could be feasible, safe, and efficacious in patients with DLBCL in Malawi. This is the first completed clinical trial on DLBCL focused on sub-Saharan African populations. Given the paucity of data on treatment of DLBCL from this region, these results could inform emerging cancer treatment programmes in sub-Saharan Africa.

Abstract
Abstract
Purpose: Persons living with HIV have elevated risks of HPV-related cervical, anogenital, and oropharyngeal cancers. Yet, research on optimization and implementation of prevention interventions (prophylactic HPV vaccination, cervical and anogenital cancer screening and triage, and precancer therapeutics) for HPV-related cancers among persons living with HIV has been limited. With a goal to expand this evidence, and building on strong academic research partnerships developed for HIV research between institutions in the US and the Latin American and the Caribbean (LAC) region, the US National Cancer Institute (NCI) initiated ULACNet, a new Cooperative Agreement clinical trials network in 2019.
Methods: ULACNet comprises of three Partnership Centers each led by US-based institutions (University of California San Francisco, Weill Medical College of Cornell University, and Fred Hutchinson Cancer Research Center), working collaboratively with US and LAC institutions and with the NCI to develop and conduct multicenter prevention clinical trials focused on filling key scientific gaps and evaluating novel interventions.
Results: ULACNet encompasses six countries (US, Mexico, Puerto Rico, Brazil, Peru, and Dominican Republic), twenty partner institutions, and over 100 collaborating scientific investigators, clinical and public health practitioners, research staff, and patient advocates. ULACNet will collaboratively conduct nine prevention clinical trials (two prophylactic HPV vaccine trials in adults and perinatally-HIV infected adolescents, three trials for clinical validation of molecular biomarkers and imaging technologies for screening and triage, two candidate HPV therapeutic vaccine trials, and two trials of topical therapeutic agents). Facilitation across network partners is achieved via a Coordinating Committee and three Working Groups (focused on HPV testing and screening, precancer treatment, and recruitment and retention activities).
Conclusion: ULACNet seeks to leverage established academic global health partnerships to conduct high quality collaborative clinical trials to inform clinical practice and ultimately reduce the burden of highly preventable HPV-related cancers in persons living with HIV worldwide.

Abstract
Abstract
Purpose: Cost-effectiveness data for cancer treatment are needed from sub-Saharan Africa (SSA), where diffuse large B-cell lymphoma (DLBCL) is a common, curable cancer. In high-income countries, the standard of care for DLBCL is R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) chemoimmunotherapy. Rituximab is often not available in SSA due to cost, and treatment with CHOP is common.
Methods: We evaluated the cost-effectiveness of DLBCL treatment using Malawi-specific data. Clinical data were from a prospective observational cohort treated with CHOP, as well as a clinical trial of R-CHOP. We used a decision-tree model to calculate costs per disability adjusted life year (DALY) averted from the health system perspective and estimated a willingness to pay (WTP) threshold of three times GDP per capita.
Results: On a per-patient level, compared to no chemotherapy, CHOP is estimated to avert 7·9 DALYS, at an incremental cost of $1,500, for an incremental cost-effectiveness ratio (ICER) of $194 per DALY averted, which is well below WTP. In probabilistic sensitivity analysis, CHOP was cost-effective for DLBCL in >99% of simulations. Compared to CHOP, R-CHOP is estimated to avert 2·9 DALYs, at an incremental cost of $3,198 and ICER of $1,104 per DALY averted, which is at the WTP threshold and was below WTP in 45% of simulations.
Conclusion: CHOP is cost-effective for DLBCL in Malawi, and the addition of rituximab may be cost-effective. Future studies in SSA and other LMIC settings should include rigorous economic evaluation to promote continued cancer treatment investments and prioritization.

Abstract
Cancer incidence and mortality are increasing in low- and middle-income countries (LMICs), where more than 75% of global cancer burden will occur by the year 2040. The primary drivers of cancer morbidity and mortality in LMICs are environmental and behavioral risk factors, inadequate prevention and early detection services, presence of comorbidities, and poor access to treatment and palliation. These same drivers also contribute to marked cancer health disparities in high-income countries. Studying cancer in LMICs provides opportunities to better understand and address these drivers to benefit populations worldwide, and reflecting this, global oncology as an academic discipline has grown substantially in recent years. However, sustaining this growth requires a uniquely trained workforce with the skills to pursue relevant, rigorous, and equitable global oncology research. Despite this need, dedicated global cancer research training programs remain somewhat nascent and uncoordinated. In this paper, we discuss efforts to address these gaps in global cancer research training at the US National Institutes of Health.

Feasibility of upfront mobile money transfers for transportation reimbursement to promote retention among patients receiving lymphoma treatment in Malawi. Int Health 2021; 13:297-304.

Abstract
BACKGROUND Cancer outcomes in sub-Saharan Africa (SSA) remain suboptimal, in part due to poor patient retention. Many patients travel long distances to receive care, and transportation costs are often prohibitively expensive. These are well-known and established causes of delayed treatment and care abandonment in Malawi and across SSA. METHODS We sent visit reminder texts and offered upfront money to cover transportation costs through a mobile money transfer (MMT) platform to lymphoma patients enrolled in a prospective cohort in Malawi. The primary aim was to test the feasibility of upfront MMTs. RESULTS We sent 1034 visit reminder texts to 189 participating patients. Of these texts, 614 (59%) were successfully delivered, with 536 (52%) responses. 320/536 (60%) MMTs were sent to interested patients and 312/320 (98%) came to their appointment on time. Of 189 total patients, 120 (63%) were reached via text and 84 (44%) received MMTs a median of three times (IQR 2-5). Median age of reachable patients was 41 (IQR 30-50), 75 (63%) were male, 62 (52%) were HIV+ and 79 (66%) resided outside of Lilongwe. CONCLUSION MMTs were a feasible way to cover upfront transportation costs for patients reachable via text, however many of our patients were unreachable. Future studies exploring barriers to care, particularly among unreachable patients, may help improve the efficacy of MMT initiatives and guide retention strategies throughout SSA.

Abstract
Malawi has the highest invasive cervical cancer (ICC) mortality rate worldwide, and ICC is the leading cause of cancer death among women. In 2004, Malawi adopted visual inspection with acetic acid (VIA) and ablative treatment with cryotherapy. However, screening coverage has remained low (<30%) and few women (<50%) who require ablative treatment receive it. Additional barriers include long distances to health facilities and challenges with maintaining gas supplies. Thermal ablation is a safe and effective alternative to cryotherapy. We assessed the safety and uptake of community-based ICC screening with VIA and same-day treatment using a handheld thermocoagulator (HTU) in rural Malawi. We held educational talks alongside community leaders and conducted VIA screening in nonclinic community settings to nonpregnant women aged 25 to 49 years without history of hysterectomy or genital cancer/precancer. Eligible women received same-day thermal ablation and HIV testing/counseling. We collected cervical biopsies before treatment and followed up women at Weeks 6 and 12, with repeat biopsy at Week 12. Between July and August 2017, 408 (88%) of 463 eligible women underwent VIA. Overall, 7% (n = 30) of women had a positive VIA, of whom 93% (n = 28) underwent same-day thermal ablation. Among the 30 VIA-positive women, 5 had cervical intraepithelial neoplasia (CIN) 1, 4 had CIN 2/3 and 21 had benign histologic findings. Abnormal vaginal discharge (60%) and light vaginal bleeding (52%) were the most reported adverse events. There was high uptake of the community-based ICC screening in the study population and treatment was safe in this setting. Similar strategies that minimize false-positive results are urgently needed in Malawi.

Abstract
Cancer is a major public health problem and the second leading cause of death worldwide. The burden of cancer continues to grow and is projected to double by 2040. This situation calls for coordinated action and emphasizes the need to join efforts on worldwide initiatives, including World Cancer Research Day (WCRD), which aims to create and consolidate a yearly momentum to raise awareness and commitment for research on cancer. Cancer research is a key driver of advances in prevention and therapeutic strategies that will benefit tomorrow's cancer patients. In 2016, 10 international organizations partnered to launch the WCRD initiative. Five years later, a total of 89 organizations and more than half a million people have joined this global movement that helps raise awareness of the importance of cancer research, demonstrating that a collaborative research culture is essential to address current challenges and create opportunities to accelerate impactful cancer research for a better future.
