Cervical Cancer in Sub-Saharan Africa: A Multinational Population-Based Cohort Study of Care and Guideline Adherence

BackgroundCervical cancer (CC) is the most common female cancer in many countries of sub‐Saharan Africa (SSA). We assessed treatment guideline adherence and its association with overall survival (OS).MethodsOur observational study covered nine population‐based cancer registries in eight countries: Benin, Ethiopia, Ivory Coast, Kenya, Mali, Mozambique, Uganda, and Zimbabwe. Random samples of 44–125 patients diagnosed from 2010 to 2016 were selected in each. Cancer‐directed therapy (CDT) was evaluated for degree of adherence to National Comprehensive Cancer Network (U.S.) Guidelines.ResultsOf 632 patients, 15.8% received CDT with curative potential: 5.2% guideline‐adherent, 2.4% with minor deviations, and 8.2% with major deviations. CDT was not documented or was without curative potential in 22%; 15.7% were diagnosed with International Federation of Gynecology and Obstetrics (FIGO) stage IV disease. Adherence was not assessed in 46.9% (no stage or follow‐up documented, 11.9%, or records not traced, 35.1%). The largest share of guideline‐adherent CDT was observed in Nairobi (49%) and the smallest in Maputo (4%). In patients with FIGO stage I–III disease (n = 190), minor and major guideline deviations were associated with impaired OS (hazard rate ratio [HRR], 1.73; 95% confidence interval [CI], 0.36–8.37; HRR, 1.97; CI, 0.59–6.56, respectively). CDT without curative potential (HRR, 3.88; CI, 1.19–12.71) and no CDT (HRR, 9.43; CI, 3.03–29.33) showed substantially worse survival.ConclusionWe found that only one in six patients with cervical cancer in SSA received CDT with curative potential. At least one‐fifth and possibly up to two‐thirds of women never accessed CDT, despite curable disease, resulting in impaired OS. Investments into more radiotherapy, chemotherapy, and surgical training could change the fatal outcomes of many patients.Implications for PracticeDespite evidence‐based interventions including guideline‐adherent treatment for cervical cancer (CC), there is huge disparity in survival across the globe. This comprehensive multinational population‐based registry study aimed to assess the status quo of presentation, treatment guideline adherence, and survival in eight countries. Patients across sub‐Saharan Africa present in late stages, and treatment guideline adherence is remarkably low. Both factors were associated with unfavorable survival. This report warns about the inability of most women with cervical cancer in sub‐Saharan Africa to access timely and high‐quality diagnostic and treatment services, serving as guidance to institutions and policy makers. With regard to clinical practice, there might be cancer‐directed treatment options that, although not fully guideline adherent, have relevant survival benefit. Others should perhaps not be chosen even under resource‐constrained circumstances.     

Results of treatment with CMA, a low intermediate regimen, in endemic Burkitt lymphomas in sub-Saharian Africa: experience of Côte d’Ivoire

African Burkitt lymphomas (BL) are highly aggressive lymphomas mainly affecting children and young adults in Africa. This lymphoma was marked by its high sensitivity to chemotherapy in comparison to Sporadic Burkitt lymphoma. In this study, we evaluated the treatment response and survival of patients with CMA protocol. Eighty-five of the 105 children registered were evaluated for response; there were 46 boys and 39 girls, whose age at diagnosis ranged from 3 to 18 years (median 11 years), admitted to the Hematology National Teaching Hospital of Abidjan in the period 1998–2008 with a diagnosis of BL on histological review and who were given CMA chemotherapy with curative intent are included in this analysis. CMA protocol is a low intermediate regimen of 3 drugs [Cytarabin (ara-C), Methotrexate (MTX), and Cyclophosphamide] with CNS-directed treatment by intrathecal MTX, ara-C and corticosteroid. Fifty-five of 85 patients obtained CR after induction therapy and 10 after 3 supplementary cycle because of partial response. The overall complete remission was 76%. Fifty-three of patients were alive in first CR at a median survival rate period of 2 years (range 82 days to 9 years) and are continuously disease free from Burkitt lymphomas. Twelve patients relapse after CR and died of lymphoma progression. More than 32 patients died, as a result of lymphoma progression. Among the 32 dead, 10 were in Murphy stage IV and all the patients who presented bone marrow involvement died. The projected 5-year overall survival rate was 62%. In conclusion, CMA protocol shows the high sensitivity of African Burkitt lymphoma. This can be considered as a successful result for people living in poor socio-economic conditions with no health insurance.     

Caractéristiques psychosociales des patients cancéreux marocains: étude de 1 000 cas recrutés à l’Institut national d’oncologie de Rabat

Résumé: Les auteurs proposent ici la première étude analysant les caractéristiques psychosociales de mille patients traités et suivis pour un cancer à l’Institut national d’oncologie de Rabat, le plus important du Maroc, qui recrute plus de six mille nouveaux cas par an. La pauvreté et l’analphabétisme constituent deux obstacles majeurs pour une bonne prise en charge. Ces deux facteurs, combinés à la berbérophonie de certains malades, limitent la communication et altèrent le transfert entre le patient et le médecin. Le cancer a des conséquences directes sur la vie quotidienne des patients: la pratique religieuse, par exemple, devient systématique chez tous les patients; des foyers conjugaux sont fragilisés, certains couples divorcent; l’entourage familial est plus solidaire et participe à la prise en charge du membre de la famille touché par la maladie.Dossier: «Cliniques du cancer»
