RESUMO

BACKGROUND: Universal access to palliative care remains a distant goal in many low resource settings, despite the growing evidence of its benefits. The unmet need for palliative care is evident in Africa, but great strides in palliative care development have occurred in several African countries. Located in sub-Saharan Africa, Malawi has been regarded as an exemplar of progress in this area that is achievable in a low resource region. This scoping review examined the literature on the development and state of palliative care in Malawi according to the pillars of health care policy, medicine availability, education, implementation, research activity, and vitality of professionals and advocates. METHODS: A scoping review was conducted of the MEDLINE, Embase, Global Health, CINAHL, Web of Science and PsycINFO databases, as well as grey literature sources. Articles were included if they explored any aspect of palliative care in Malawi. RESULTS: 114 articles were identified that met the inclusion criteria. This literature shows that Malawi has implemented diverse strategies across all pillars to develop palliative care. These strategies include creating a national stand-alone palliative care policy; integrating palliative care into the curricula of healthcare professionals and developing training for diverse service providers; establishing systems for the procurement and distribution of opioids; implementing diverse models of palliative care service delivery; and launching a national palliative care association. Malawi has also generated local evidence to inform palliative care, but several research gaps were identified. CONCLUSIONS: Malawi has made considerable progress in palliative care development, although initiatives are needed to improve medicine availability, access in rural areas, and socioeconomic support for patients and their families living with advanced disease. Culturally sensitive research is needed regarding the quality of palliative care and the impact of therapeutic interventions.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: Contemporary descriptions of classical Hodgkin lymphoma (cHL) are lacking from sub-Saharan Africa where human immunodeficiency virus (HIV) and Epstein-Barr virus (EBV) are prevalent. METHODS: We describe a prospective cHL cohort in Malawi enrolled from 2013 to 2015. Patients received standardized treatment and evaluation, including HIV status and EBV testing of tumors and plasma. RESULTS: Among 31 patients with confirmed cHL, the median age was 19 years (range, 2-51 years) and 22 (71%) were male. Sixteen patients (52%) had stage III/IV, 25 (81%) B symptoms, and 16 (52%) performance status impairment. Twenty-three patients (74%) had symptoms >6 months, and 11 of 29 (38%) had received empiric antituberculosis treatment. Anemia was common with median hemoglobin 8.2 g/dL (range, 3.1-17.1 g/dL), which improved during treatment. No children and 5 of 15 adults (33%) were HIV+. All HIV+ patients were on antiretroviral therapy for a median 15 months (range, 2-137 months), with median CD4 count 138 cells/µL (range, 23-329 cells/µL) and four (80%) having undetectable HIV. EBV was present in 18 of 24 (75%) tumor specimens, including 14 of 20 (70%) HIV- and 4 of 4 (100%) HIV+. Baseline plasma EBV DNA was detected in 25 of 28 (89%) patients, with median viral load 4.7 (range, 2.0-6.7) log10 copies/mL, and subsequently declined in most patients. At 12 months, overall survival was 75% (95% confidence interval [CI], 55%-88%) and progression-free survival 65% (95% CI, 42%-81%). Baseline plasma EBV DNA and persistent viremia during treatment were associated with poorer outcomes. CONCLUSION: cHL in Malawi is characterized by delayed diagnosis and advanced disease. Most cases were EBV associated and one-third of adults were HIV+. Despite resource limitations, 12-month outcomes were good.

RESUMO

Background: ABVD (doxorubicin, bleomycin, vinblastine, and dexamethasone) is a proven, curative regimen for Hodgkin lymphoma (HL). Prospective data describing HL treatment in sub-Saharan Africa are limited. We aimed to fill this knowledge gap, using data from Malawi. Methods: We report a prospective observational cohort of HL (aged ≥ 15) from a single, tertiary referral centre in Malawi. We enrolled patients with pathologicially confirmed Hodgkin lymphoma between June 1, 2013, and Dec 31, 2021 with follow-up censored on May 31, 2022. Patients were treated with ABVD and concurrent antiretroviral therapy if HIV-positive and were followed up for 5 years. The primary outcome was overall survival; secondary outcomes included progression-free survival, response assessment, and adverse events. Microcosting of HL diagnosis, treatment, and follow-up was embedded. Findings: We enrolled 38 patients with a median age of 27 years (interquartile range 19-46); eleven (28%) were HIV-positive. Of 35 patients treated with ABVD, 24 (71%) had stage III/IV, nine (26%) unfavourable limited stage, and two (6%) favourable limited stage. Among HIV-infected individuals, mean CD4 count at HL diagnosis was 179 cells/uL and ten (91%) had HIV RNA < 400 copies/mL. Grade 3/4 neutropenia occurred in 24 (68%) patients and caused treatment delay in 16 (46%). Of ten deaths, seven were due to HL, two possible treatment-related toxicity, and one uncertain. 2-year overall survival was 82% (95% CI 70-96%) and 2-year progression-free survival was 64% (95% CI 50-83%). PFS appeared better for HIV-positive patients (HR 0.23 (95% CI 0.05-1.02)) after controlling for stage and performance status (p = 0.05). We estimated $2708 (2022 USD) for HL diagnosis, treatment, and follow-up in our cohort. Interpretation: Our findings suggest that treatment with ABVD is safe, efficacious, and affordable for HL in Malawi. Outcomes are worse than in high-income countries due to HL progression. Future studies are needed to understand outcome inequities and to assess efficacy of therapies for patients with relapsed or refractory HL in Malawi.

RESUMO

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.

RESUMO

INTRODUCTION: Evaluating the quality of dying and death is essential to ensure high-quality end-of-life care. The Quality of Dying and Death (QODD) scale is the best-validated measure of the construct, but many items are not relevant to participants, particularly in low-resource settings. The aim of this multisite cross-sectional study is to develop and validate the QODD-Revised Global Version (QODD-RGV), to enhance ease of completion and relevance in higher-resource and lower-resource settings. METHODS AND ANALYSIS: This study will be a two-arm, multisite evaluation of the cultural relevance, reliability and validity of the QODD-RGV across four participating North American hospices and a palliative care site in Malawi, Africa. Bereaved caregivers and healthcare providers of patients who died at a participating North American hospice and bereaved caregivers of patients who died of cancer at the Malawian palliative care site will complete the QODD-RGV and validation measures. Cognitive interviews with subsets of North American and Malawian caregivers will assess the perceived relevance of the scale items. Psychometric evaluations will include internal consistency and convergent and concurrent validity. ETHICS AND DISSEMINATION: The North American arm received approval from the University Health Network Research Ethics Board (21-5143) and the University of North Carolina Institutional Review Board (21-1172). Ethics approval for the Malawi arm is being obtained from the University of North Carolina Institutional Review Board and the Malawian National Health Science Research Committee. Study findings will be disseminated through publication in peer-reviewed journals and conference presentations.

RESUMO

CONTEXT: Outcomes for children with cancer in sub-Saharan Africa (SAA) are dismal due to delayed diagnosis and limited access to curative therapy. When establishing a pediatric hematology-oncology (PHO) program in low-resource settings, early integration of palliative care services becomes essential. While palliative care is a human right, equitable distribution is lacking. OBJECTIVES: We aim to describe our experience establishing a palliative care program, the services offered, and the distribution of patients served. METHODS: This is a brief description of our PHO palliative care program in Lilongwe, Malawi at a tertiary care center and a three-year retrospective review of activities (2017-2020). Services offered include inpatient, outpatient, home visits, end of life care, and strengthening of referral systems. RESULTS: Over the three-year period, 315 patients were enrolled. 57% (n=179) were male. The median age was seven years (5 months-22 years). Patients served were from 17 of 28 districts within Malawi. Diagnoses of patients included 43% solid tumors (n=135), 22% lymphoma (n=68), 15% leukemia (n=47), and 21% hematologic disease (n=65). 40% of patients have died (n=125), with 53% of deaths occurring at home (n=66), 22% in the hospital (n=28), and 25% at unknown locations (n=31). CONCLUSION: Palliative care is a critical component of PHO programs worldwide. Programs must leverage existing networks to ensure optimal care to children and families. We demonstrate the feasibility of integrating palliative care services within a PHO program in a low-resource setting, which could serve as a model for other countries in SSA.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

Aggressive non-Hodgkin lymphoma (NHL) is among the most common cancers in sub-Saharan Africa (SSA), where CHOP is standard treatment and outcomes are poor. To address this, we treated 17 newly diagnosed adult patients in Malawi with Burkitt (n = 8), plasmablastic (n = 8), and primary effusion lymphoma (n = 1) with a modified EPOCH regimen between 2016 and 2019. Twelve patients (71%) were male and the median age was 40 years (range 16-63). Eleven (65%) were HIV infected, median CD4 count was 218 cells/µL (range 9-460), and nine (82%) had suppressed HIV RNA < 400 copies/mL. Patients received a median of six cycles (range 2-8) and median follow-up was 14 months (range 2-34) among patients still alive. Grade 3/4 neutropenia was observed in 26% of cycles and in 65% of patients. Sixteen (94%) responded to EPOCH and 10 (59%) achieved a complete response. One-year overall survival (OS) was 62% (95% confidence interval [CI], 42%-91%). Five patients (29%) died from progressive NHL and three (18%) from treatment-related complications. These data suggest EPOCH with setting-appropriate modifications may be a practical, safe, and effective option for improving high-risk NHL outcomes in Malawi and comparable settings, which deserves further prospective evaluation.

RESUMO

BACKGROUND: Increasing access to conventional cancer treatment (CT) in low-income countries (LICs) is an important public health initiative to address the global burden of cancer. However, LICs have a high prevalence of use of traditional and complementary medicine (T&CM). It is important to consider the factors that influence a patient's choice to use T&CM, CT, or both for their cancer treatment. METHODS: We conducted focus groups among adult cancer patients in Lilongwe, Malawi to identify facilitators and barriers of T&CM use. Focus groups were recorded, transcribed, translated, and underwent thematic content analysis. RESULTS: Cultural norms, T&CM access, T&CM success, and CT failure were all identified as facilitators to T&CM use. CT success and T&CM failure were identified as barriers. Access and norms appear to determine initial treatment selection, while treatment outcomes dictate continued use of T&CM or CT. CONCLUSION: This study identified a pragmatic and experience-based treatment selection process that aligns with the social cognitive theory of behavior and assists in comprehending the factors that influence T&CM use among cancer patients in a low resource setting.

Plasmablastic lymphoma (PBL) clinical descriptions are scarce from sub-Saharan Africa (SSA) where both HIV and EBV are highly endemic. We identified 12 patients with pathologically confirmed PBL from a prospective cohort in Lilongwe, Malawi. Median age was 46 (range 26-71), seven (58%) were male, and six (50%) were HIV-positive. Eight patients were treated with CHOP and four with a modified EPOCH regimen. One-year overall survival was 56% (95% CI 24-79%), without clear differences based on HIV status. PBL occurs in Malawi in HIV-positive and HIV-negative individuals and can be treated successfully with curative intent, even in a low-resource setting in SSA.

RESUMO

Given scarce data from sub-Saharan Africa (SSA), we sought to describe CD4 count and HIV RNA trends over time among patients with HIV-positive lymphoproliferative disorders in Malawi. We prospectively enrolled HIV-positive individuals with pathologically confirmed lymphoproliferative disorders between 2013 and 2016. Chemotherapy was standardized with concurrent antiretroviral therapy (ART). We assessed CD4 count and HIV RNA at baseline and every 6 months for up to 2 years. Of 72 HIV-positive patients, 59 had non-Hodgkin lymphoma (NHL), 5 classical Hodgkin lymphoma (CHL), and 8 multicentric Castleman disease (MCD). Median age was 43 years (range 23-64). Fifty-five patients (76%) were on ART at enrollment for a median 47 months (range 1-387), with median CD4 count of 138 cells/µl (range 2-2,235) and median HIV RNA of 2.2 log10copies/ml (range 0.3-7.3). MCD patients had longer median ART durations, higher median CD4 counts, and lower median HIV RNA at baseline than NHL or CHL patients. CD4 count and HIV RNA steadily improved during follow-up, with different patterns in different histological groups. Twelve-month overall survival (OS) was 55% [95% confidence interval (CI) 42%-66%]. There were trends toward baseline CD4 count <100 cells/µl and HIV RNA >2.0 log10copies/ml being associated with worse OS. However, CD4 count and HIV RNA improvements during follow-up were independent of possible effects on OS. Distribution of HIV-positive lymphoproliferative disorders may change with continued ART scale-up in SSA. Chemotherapy and concurrent ART can lead to good immunological and virological outcomes.

RESUMO

BACKGROUND: Lymphoma is highly associated with HIV in sub-Saharan Africa (SSA), which contributes to worse outcomes relative to resource-rich settings, and frequent failure of first-line chemotherapy. However, there are no second-line treatment descriptions for adults with relapsed or refractory lymphoma (RRL) in SSA. METHODS: We describe HIV+ and HIV- patients with RRL receiving salvage chemotherapy in Malawi. Patients were prospectively treated at a national teaching hospital in Lilongwe, with the modified EPIC regimen (etoposide, prednisolone, ifosfamide, cisplatin) between June 2013 and May 2016, after failing prior first-line chemotherapy. RESULTS: Among 21 patients (18 relapsed, 3 refractory), median age was 40 years (range 16-78), 12 (57%) were male. Thirteen patients (62%) were HIV+, of whom 12 (92%) were on antiretroviral therapy (ART) at initiation of salvage chemotherapy, with median CD4 cell count 139 cells/µL (range 12-529) and 11 (85%) with suppressed HIV RNA. Median number of EPIC cycles was 3 (range 1-6), and the commonest toxicity was grade 3/4 neutropenia in 19 patients (90%). Fifteen patients responded (3 complete, 12 partial, overall response rate 71%), but durations were brief. Median overall survival was 4.5 months [95% confidence interval (CI) 2.4-5.6]. However, three patients, all HIV+, experienced sustained remissions. Tolerability, response, and survival did not differ by HIV status. CONCLUSIONS: The appropriateness and cost-effectiveness of this approach in severely resource-limited environments is uncertain, and multifaceted efforts to improve first-line lymphoma treatment should be emphasized, to reduce frequency with which patients require salvage chemotherapy.

RESUMO

BACKGROUND: Little is known about risk factors for different cancers in Malawi. This study aimed to assess risk factors for and epidemiologic patterns of common cancers among patients treated at Kamuzu Central Hospital (KCH) in Lilongwe, and to determine the prevalence of Human Immunodeficiency Virus (HIV) infection in the same population. METHODS: We analysed data from the hospital-based KCH cancer registry, from June 2009 to September 2012, including data from a nested substudy on coinfections among cancer patients. Demographics and behavioural variables, including smoking and alcohol use, were collected through personal interviews with patients. We assessed HIV prevalence across cancer types. The distribution of cancer types was reported overall and by gender. Logistic regression was used to assess risk factors associated with common cancer types. RESULTS: Data from 504 registered cancer patients were included-300 (59.5%) were female and 204 (40.5%) were male. Mean age was 49 years (standard deviation, SD = 16). There were 343 HIV-negative patients (71.2%), and 139 (28.8%) were HIV-positive. The commonest cancers were oesophageal (n = 172; 34.5%), cervical (n = 109; 21.9%), and Kaposi's sarcoma (KS) (n = 52; 10.4%). Only 18% of cancer cases were histologically confirmed. Patients with oesophageal cancer were likely to be older than 50 years (odds ratio, OR = 2.22), male (OR = 1.47), and smokers (OR = 2.02). Kaposi's sarcoma patients had the highest odds (OR = 54.4) of being HIV-positive and were also more likely to be male (OR = 6.02) and smokers. Cervical cancer patients were more likely to be HIV-positive (OR = 2.2) and less than 50 years of age. CONCLUSIONS: Age, smoking, and HIV are important risk factors for the 3 commonest cancer types (oesophageal, KS, and cervical) at this teaching hospital in Malawi. HIV is the single most important risk factor for Kaposi's sarcoma and cervical cancer.

RESUMO

There are no prospective studies of aggressive non-Hodgkin lymphoma (NHL) treated with CHOP in sub-Saharan Africa. We enrolled adults with aggressive NHL in Malawi between June 2013 and May 2015. Chemotherapy and supportive care were standardized, and HIV+ patients received antiretroviral therapy (ART). Thirty-seven of 58 patients (64%) were HIV+. Median age was 47 years (IQR 39-56), and 35 (60%) were male. Thirty-five patients (60%) had stage III/IV, 43 (74%) B symptoms, and 28 (48%) performance status ≥ 2. B-cell NHL predominated among HIV+ patients, and all T-cell NHL occurred among HIV- individuals. Thirty-one HIV+ patients (84%) were on ART for a median 9.9 months (IQR 1.1-31.7) before NHL diagnosis, median CD4 was 121 cells/µL (IQR 61-244), and 43% had suppressed HIV RNA. HIV+ patients received a similar number of CHOP cycles compared to HIV- patients, but more frequently developed grade 3/4 neutropenia (84% vs 31%, p = 0.001), resulting in modestly lower cyclophosphamide and doxorubicin doses with longer intervals between cycles. Twelve-month overall survival (OS) was 45% (95% CI 31-57%). T-cell NHL (HR 3.90, p = 0.017), hemoglobin (HR 0.82 per g/dL, p = 0.017), albumin (HR 0.57 per g/dL, p = 0.019), and IPI (HR 2.02 per unit, p<0.001) were associated with mortality. HIV was not associated with mortality, and findings were similar among patients with diffuse large B-cell lymphoma. Twenty-three deaths were from NHL (12 HIV+, 11 HIV-), and 12 from CHOP (9 HIV+, 3 HIV-). CHOP can be safe, effective, and feasible for aggressive NHL in Malawi with and without HIV.

RESUMO

INTRODUCTION: Clinical reports of multicentric Castleman disease (MCD) from sub-Saharan Africa (SSA) are scarce despite high prevalence of HIV and Kaposi sarcoma-associated herpesvirus (KSHV). Our objective is to describe characteristics and survival for HIV-associated MCD patients in Malawi. To our knowledge, this is the first HIV-associated MCD case series from the region. METHODS: We describe HIV-positive patients with MCD in Lilongwe, and compare them to HIV-associated lymph node Kaposi sarcoma (KS) and non-Hodgkin lymphoma (NHL) patients treated at our centre. All patients were enrolled into a prospective longitudinal cohort study at a national teaching hospital and cancer referral centre serving half of Malawi's 16 million people. We included adult patients≥18 years of age with HIV-associated MCD (n=6), lymph node KS (n=5) or NHL (n=31) enrolled between 1 June 2013 and 31 January 2015. RESULTS AND DISCUSSION: MCD patients had a median age of 42.4 years (range 37.2-51.8). All had diffuse lymphadenopathy and five had hepatosplenomegaly. Concurrent KS was present for one MCD patient, and four had performance status ≥3. MCD patients had lower median haemoglobin (6.4 g/dL, range 3.6-9.3) than KS (11.0 g/dL, range 9.1-12.0, p=0.011) or NHL (11.2 g/dL, range 4.5-15.1, p=0.0007). Median serum albumin was also lower for MCD (2.1 g/dL, range 1.7-3.2) than KS (3.7 g/dL, range 3.2-3.9, p=0.013) or NHL (3.4 g/dL, range 1.8-4.8, p=0.003). All six MCD patients were on antiretroviral therapy (ART) with median CD4 count 208 cells/µL (range 108-1146), and all with HIV RNA <400 copies/mL. Most KS and NHL patients were also on ART, although ART duration was longer for MCD (56.4 months, range 18.2-105.3) than KS (14.2 months, range 6.8-21.9, p=0.039) or NHL (13.8 months, range 0.2-98.8, p=0.017). Survival was poorer for MCD patients than lymph node KS or NHL. CONCLUSIONS: HIV-associated MCD occurs in Malawi, is diagnosed late and is associated with high mortality. Improvements in awareness, diagnostic facilities, treatment and supportive care are needed to address this likely under-recognized public health problem in SSA.
