ABSTRACT

BACKGROUND: Over the past decade, assessments of surgical capacity in low- and middle-income countries (LMICs) have contributed to our understanding of barriers to the delivery of surgical services in a number of countries. It is yet unclear, however, how the findings of these assessments have been applied and built upon within the published literature. METHODS: A systematic literature review of surgical capacity assessments in LMICs was performed to evaluate current levels of understanding of global surgical capacity and to identify areas for future study. A reverse snowballing method was then used to follow-up citations of the identified studies to assess how this research has been applied and built upon in the literature. RESULTS: Twenty-one papers reporting the findings of surgical capacity assessments conducted in 17 different LMICs in South Asia, East Asia and Pacific, Latin America and the Caribbean, and sub-Saharan Africa were identified. These studies documented substantial deficits in human resources, infrastructure, equipment, and supplies. Only seven additional papers were identified which applied or built upon the studies. Among these, capacity assessment findings were most commonly used to develop novel tools and intervention strategies, but they were also used as baseline measurements against which updated capacity assessments were compared. CONCLUSIONS: While the global surgery community has made tremendous progress in establishing baseline values of surgical capacity in LMICs around the world, further work is necessary to build upon and apply the foundational knowledge established through these efforts. Capacity assessment data should be coordinated and used in ongoing research efforts to monitor and evaluate progress in global surgery and to develop targeted intervention strategies. Intervention strategy development may also be further incorporated into the evaluation process itself.

ABSTRACT

Wilms tumour is a relatively common and curable paediatric tumour. Known challenges to cure in low income countries are late presentation with advanced disease, malnutrition, failure to complete treatment and limited facilities. In this article, management recommendations are given for a low income setting where only the minimal requirements for treatment with curative intent are available (setting 1). These include general management, supportive care, social support and registration of patients. Recommendations specific for Wilms tumour care include diagnostic procedures with emphasis on the role of ultrasonography, preoperative chemotherapy with a reduced dosage for malnourished children and postoperative chemotherapy based on surgical staging.

ABSTRACT

The care of children with malignant solid tumors in sub-Saharan Africa is compromised by resource deficiencies that range from inadequate healthcare budgets and a paucity of appropriately trained personnel, to scarce laboratory facilities and inconsistent drug supplies. Patients face difficulties accessing healthcare, affording investigational and treatment protocols, and attending follow-up. Children routinely present with advanced local and metastatic disease and many children cannot be offered any effective treatment. Additionally, multiple comorbidities, including malaria, tuberculosis, and HIV when added to acute on chronic malnutrition, compound treatment-related toxicities. Survival rates are poor. Pediatric surgical oncology is not yet regarded as a health care priority by governments struggling to achieve their millennium goals. The patterns of childhood solid malignant tumors in Africa are discussed, and the difficulties encountered in their management are highlighted. Three pediatric surgeons from different regions of Africa reflect on their experiences and review the available literature. The overall incidence of pediatric solid malignant tumor is difficult to estimate in Africa because of lack of vital hospital statistics and national cancer registries in most of countries. The reported incidences vary between 5% and 15.5% of all malignant tumors. Throughout the continent, patterns of malignant disease vary with an obvious increase in the prevalence of Burkitt lymphoma (BL) and Kaposi sarcoma in response-increased prevalence of HIV disease. In northern Africa, the most common malignant tumor is leukemia, followed by brain tumors and nephroblastoma or neuroblastoma. In sub-Saharan countries, BL is the commonest tumor followed by nephroblastoma, non-Hodgkin lymphoma, and rhabdomyosarcoma. The overall 5-years survival varied between 5% (in Côte d'Ivoire before 2001) to 34% in Egypt and up to 70% in South Africa. In many reports, the survival rate of patients is not mentioned but is clearly very low in many sub-Saharan Africa countries (Sudan, Nigeria). Late presentation was observed for many tumors like nephroblastoma in Nigeria, 72% were stages III and IV or BL stages III and IV were observed in 40% and 30%, respectively. Africa bears a great burden of childhood cancer. Cancer is now curable in developed countries as survival rates approach 80%, but in Africa, >80% of children still die without access to adequate treatment. Sharpening the needlepoint of surgical expertise will, of itself, not compensate for the major infrastructural deficiencies, but must proceed in tandem with resource development and allow heath planners to realize that pediatric surgical oncology is a cost-effective service that can uplift regional services.

ABSTRACT

AIMS: AIDS-associated myoid tumours (AIDS-MTs), often Epstein-Barr virus (EBV)-associated (EBV-positive MTs), include smooth muscle tumors (SMTs) and the relatively recently recognized myopericytomas (MPCTs). The myoid immunophenotype of AIDS-MTs has been documented inconsistently. The aim of this study was to reappraise the phenotypic and immunophenotypic features of extra-uterine AIDS-MTs and the clinical profile of afflicted patients. METHODS AND RESULTS: EBV early RNA in-situ hybridization testing on 27 AIDS-MTs from 25 patients identified 19 of 27 (70.4%) EBV-positive MTs and eight of 27 (29.6%) EBV-negative MTs. EBV-positive MTs comprised 12 of 19 EBV-positive SMTs [six leiomyomas, one smooth muscle tumour of uncertain malignant potential (STUMP), five leiomyosarcomas] and seven of 19 EBV-positive MPCTs [benign (five), malignant (two)]. The EBV-negative MTs, made up exclusively of EBV-negative SMTs, included angioleiomyoma (one), leiomyoma (one), STUMP (one) and leiomyosarcomas (five). Malignant AIDS-MTs demonstrated hypercellularity, pleomorphism, increased mitoses and necrosis. EBV-positive leiomyosarcomas retained a conspicuous fascicular architecture. Four of five EBV-negative leiomyosarcomas demonstrated marked pleomorphism. All EBV-positive MPCTs and two EBV-positive leiomyosarcomas contained aggregates of desmin-negative round and oval cells. Seventeen of 25 patients died, mainly from comorbid diseases. CONCLUSION: While the reappraised spectrum of AIDS-MTs does not demonstrate divergent subtype-determined clinical behaviour, heightened awareness/recognition of this expanded spectrum will not only promote improved diagnosis of pleomorphic and myopericytic variants, which may be the sentinel clue to AIDS and its comorbidity, but will also facilitate distinction from histopathological mimics in specific anatomic locations.
