Abstract
Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of lymphoma worldwide, accounting for up to 40% of new non-Hodgkin Lymphoma (NHL) globally. People living with HIV are up to 17 times more likely to develop NHL, and as such, DLBCL is the leading cause of cancer death in this high-risk population. While histologically indistinguishable, HIV-associated (HIV+) and HIV-negative (HIV-) DLBCL are molecularly distinct, and biological differences may have implications for the development of future therapeutic interventions. Further, the impact of immunologic differences in people with HIV, including preceding ART, remains largely unknown. Here, we investigate the impact of HIV infection and ART exposure on the clinical features of DLBCL and T-cell immune response by performing imaging mass cytometry on our unique patient cohort in Malawi. In this cohort, HIV infection is positively prognostic, and HIV+/ART-naïve patients have the best outcomes. No established biomarkers other than Ki67 are associated with HIV or ART status, and the only tumour-intrinsic biomarkers that remain prognostic are MYC and MYC/BCL2 protein co-expression. Finally, TCR clonality is associated with distinct tumour-T cell interactions by HIV/ART status, indicating differential anti-tumour immune responses. We demonstrate previously undescribed HIV and ART-related differences in the DLBCL tumour microenvironment.

Abstract
The pathology laboratory at Kamuzu Central Hospital (KCH) in Lilongwe, Malawi was established in 2011. We published our initial experiences in laboratory development and telepathology in 2013 and 2016, respectively. The purpose of this paper is to provide an update on our work by highlighting the positive role laboratory development has played in improving regional cancer care and research. In addition, we provide a summary of the adult pathology data from specimens received between July 1, 2011, and May 31, 2019, with an emphasis on malignant diagnoses. We compare these summaries to estimates of cancer incidence in this region to identify gaps and future needs.

Abstract
Background Oncology teams are encouraged to include patient preferences and goals of care in determining appropriate treatment courses. There are no existing data from Malawi exploring decision-making preferences among cancer patients. Methods In the oncology clinic in Lilongwe, Malawi, 50 patients were surveyed for decision making. Results Most participants (70%, n = 35) preferred to engage in shared decision making regarding cancer treatment. About half (52%, n = 24) did not feel that their medical team involved them in decision making and 64% (n = 32) felt that they were never or only sometimes listened to by the medical team. Nearly all (94%, n = 47) preferred to have their medical team inform them how likely treatments are to lead to cure. Conclusions Shared decision making was the preferred mode of treatment decision making by the majority of the surveyed cancer patients in Malawi. Cancer patients in Malawi may have similar preferences to cancer patients in other low-resource settings regarding decision making and communication.

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.

Comparison of best supportive care, CHOP, or R-CHOP for treatment of diffuse large B-cell lymphoma in Malawi: a cost-effectiveness analysis. Lancet Glob Health 2021; 9:e1305-e1313. [PMID: 34303416 PMCID: PMC8403678 DOI: 10.1016/s2214-109x(21)00261-8] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2020] [Revised: 05/05/2021] [Accepted: 05/25/2021] [Indexed: 12/24/2022]
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
PURPOSE To describe the cost of treating diffuse large B-cell lymphoma (DLBCL) in Malawi under the following circumstances: (1) palliation only, (2) first-line cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP), (3) salvage etoposide, ifosfamide, and cisplatin (EPIC), and (4) salvage gemcitabine and oxaliplatin (GEMOX). METHODS We conducted a microcosting analysis from the health system perspective in the context of a prospective cohort study at a national teaching hospital in Lilongwe, Malawi. Clinical outcomes data were derived from previously published literature from the cohort. Cost data were collected for treatment and 2-year follow-up, reflecting costs incurred by the research institution or referral hospital for goods and services. Costs were collected in Malawian kwacha, inflated and converted to 2017 US dollars. RESULTS On a per-patient basis, palliative care alone cost $728 per person. Total costs for first-line treatment with CHOP chemotherapy was $1,844, of which chemotherapy drugs made up 15%. Separate salvage EPIC and GEMOX cost $2,597 and $3,176, respectively. Chemotherapy drugs accounted for 30% of EPIC and 47% of GEMOX. CONCLUSION To our knowledge, this is among the first published efforts to characterize detailed costs of cancer treatment in sub-Saharan Africa. The per-patient cost of first-line treatment of DLBCL in Malawi is low relative to high-income countries, suggesting that investments in fixed-duration, curative-intent DLBCL treatment may be attractive in sub-Saharan Africa. Salvage treatment of relapsed/refractory DLBCL costs much more than first-line therapy. Formal cost-effectiveness modeling for CHOP and salvage treatment in the Malawian and other low-resource settings is needed to inform decision makers about optimal use of resources for cancer treatment.

Prospective study of Burkitt lymphoma treatment in adolescents and adults in Malawi. Blood Adv 2020; 3:612-620.

Abstract
Burkitt lymphoma (BL) is common in sub-Saharan Africa (SSA). In high-income countries, BL is highly curable with chemotherapy. However, there are few prospective studies from SSA describing nonpediatric BL and no regional standard of care. Thirty-five participants age 15 years or older with newly diagnosed BL were enrolled in Malawi from 2013 to 2018. Chemotherapy was administered according to institutional guidelines, with concurrent antiretroviral therapy if HIV infected. Median age was 21 years (range, 15-61) and 15 participants (43%) were HIV infected. Twenty-seven participants (77%) had stage III to IV disease, and 19 (54%) had Eastern Cooperative Oncology Group performance status >1. Among HIV-infected participants, median CD4 count was 130 (range, 29-605) and 10 (67%) had suppressed HIV viral load. Four participants (11%) died before receiving chemotherapy. First-line chemotherapy consisted of: cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) (n = 22 [71%]); infusional etoposide, prednisolone, vincristine, cyclophosphamide, and doxorubicin (n = 4 [13%]); high-dose methotrexate-based chemotherapy (n = 4 [13%]); and rituximab plus CHOP (n = 1 [3%]). Among 28 evaluable participants, 14 (50%) achieved a complete response. Median overall survival (OS) was 7 months; 1-year OS was 40% (95% confidence interval [CI], 24%-56%). Sixteen (73%) of 22 deaths were a result of disease progression. Compared with CHOP, more intensive chemotherapy was associated with decreased mortality (hazard ratio, 0.24; 95% CI, 0.05-1.02; P = .05). This is among the best characterized prospective cohorts of nonpediatric BL in SSA. Most deaths resulted from progressive BL. Patients who received more intensive therapy seemed to have better outcomes. Defining optimal approaches is an urgent priority in SSA.

Abstract
Outcomes for diffuse large B-cell lymphoma (DLBCL) in sub-Saharan Africa (SSA) are poorly described. We report mature data from one of the first prospective SSA cohorts. Patients aged ≥18 years with DLBCL were enrolled in Malawi 2013-2017. Participants were treated with CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) chemotherapy and concurrent antiretroviral therapy (ART) if positive for human immunodeficiency virus (HIV+). Eighty-six participants (mean age 47 years, standard deviation 13) were enrolled: 54 (63%) were male and 51 (59%) were HIV+, of whom 34 (67%) were on ART at DLBCL diagnosis. Median CD4 count was 0·113 cells × 109 /l (interquartile range [IQR] 0·062-0·227) and 25 (49%) had HIV viral load <400 copies/μl. Participants received median six cycles CHOP (IQR 4-6). No patients were lost to follow-up and the 2-year overall survival was 38% (95% confidence interval 28-49). In multivariable analyses, Eastern Cooperative Oncology Group performance status (PS) ≥2 and lactate dehydrogenase (LDH) >2× upper limit of normal (ULN) were associated with mortality. HIV status was not associated with mortality. A simplified prognostic model of LDH >2× ULN and PS ≥2 performed at least as well as the age-adjusted International Prognostic Index. DLBCL can be successfully treated in SSA and outcomes did not differ by HIV status. A simplified prognostic model prognosticates well and may be easier to use in resource-limited settings but requires validation.

Abstract
Purpose The purpose of this study was to evaluate the economic burden of frontline failure (FLF) among classical Hodgkin lymphoma (HL) patients during and after treatment. Patients and methods The population consisted of adult HL patients identified from January 2010 through September 2015 without any other primary cancer prior to HL diagnosis, who also had a frontline (FL) regimen indicative of curative intent. Patients were characterized as FLF (those who restart, switch to any chemotherapy; had a hematopoietic stem cell transplant; or newly initiated radiation therapy [RT] after discontinuing FL) or non-FLF (those not considered as FLF). Direct health care utilization and expenditures were measured over both fixed and variable length follow-up periods and during FL therapy. Results There were 77 FLF and 602 non-FLF patients who met the final inclusion criteria. FLF and non-FLF patients were demographically similar with mean age 38.5 years and 47.5% females. Average per patient per month (PPPM) costs were significantly higher for FLF patients during all follow-up (US$20,266 vs US$7,772, P<0.05). Annual total expenditures were significantly higher among FLF patients (US$198,388) vs non-FLF patients (US$37,549). FLF (vs non-FLF) patients had a significantly shorter duration of FL therapy (116 vs 131 days, P=0.024) and higher total PPPM expenditures during FL (US$29,040 vs US$16,369, P<0.05). Annual cost varied by failure type with those who failed due to restart incurring the highest cost (US$269,189) and those who switched incurring the lowest cost (US$46,951). FLF patients had a significantly greater utilization in every health care resource category during follow-up. Conclusion FLF (vs non-FLF) patients utilized substantially more health care resources and incurred a substantially higher economic burden. Over 5 years, FLF patients with at least two lines of treatment were projected to incur US$535,846 of health care costs. Further research is needed to determine optimal treatment that could reduce the risk of progression, need for treatment after FL, and enhance long-term clinical and economic outcomes.

How I treat Burkitt lymphoma in children, adolescents, and young adults in sub-Saharan Africa. Blood 2018; 132:254-263. [PMID: 29769263 DOI: 10.1182/blood-2018-04-844472] [Citation(s) in RCA: 33] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2018] [Accepted: 05/14/2018] [Indexed: 12/16/2022] Open
Abstract
Burkitt lymphoma (BL) is the most common pediatric cancer in sub-Saharan Africa (SSA), and also occurs frequently among adolescents and young adults (AYAs), often associated with HIV. Treating BL in SSA poses particular challenges. Although highly effective, high-intensity cytotoxic treatments used in resource-rich settings are usually not feasible, and lower-intensity continuous infusion approaches are impractical. In this article, based on evidence from the region, we review management strategies for SSA focused on diagnosis and use of prephase and definitive treatment. Additionally, potentially better approaches for risk stratification and individualized therapy are elaborated. Compared with historical very low-intensity approaches, the relative safety, feasibility, and outcomes of regimens incorporating anthracyclines and/or high-dose systemic methotrexate for this population are discussed, along with requirements to administer such regimens safely. Finally, research priorities for BL in SSA are outlined including novel therapies, to reduce the unacceptable gap in outcomes for patients in SSA vs high-income countries (HICs). Sustained commitment to incremental advances and innovation, as in cooperative pediatric oncology groups in HICs, is required to transform care and outcomes for BL in SSA through international collaboration.
