Case report: Turcot syndrome type 2 in a developing country within the Caribbean.

Medulloblastoma is the most common malignant pediatric brain tumor and has been linked to known cancer predisposition syndromes. We report a case of medulloblastoma of a 12-year-old Indo-Trinidadian female with a strong family history of colorectal carcinoma. In collaboration with the SickKids-Caribbean Initiative (SCI), her tumor was confirmed to be a WHO grade 4 medulloblastoma - Wnt subtype. Genetic testing further confirmed the presence of a pathogenic APC gene variant [c.3183_3187del (p.Gln1062*)] which led to a diagnosis of Turcot syndrome type 2. The index patient received multimodal therapy which included surgery, radiation and chemotherapy and is currently post end-of-treatment and in remission. This case report aims to highlight the complexity of diseases and the need for expertise in identifying them in low-and-middle income countries, the need for access to specialized testing and the benefits of collaborating between low-and-middle income and high-income countries when managing complex oncology patients.

Developing a partnership to improve health care delivery to children <18 years with cancer and blood disorders in the English-speaking Caribbean: lessons from the SickKids-Caribbean Initiative (SCI).

In 2013, the SickKids-Caribbean Initiative (SCI) was formalised among The Hospital for Sick Children in Toronto, Canada, the University of the West Indies, and Ministries of Health in six Caribbean countries (Barbados, The Bahamas, Jamaica, St. Lucia, St. Vincent and the Grenadines, and Trinidad and Tobago). The aim was to improve the outcomes and quality of life of children (<18 years) with cancer and blood disorders in the partner countries. Core activities included filling a human resource gap by training paediatric haematologists/oncologists and specialised registered nurses; improving capacity to diagnose and treat diverse haematology/oncology cases; developing and maintaining paediatric oncology databases; creating ongoing advocacy activities with international agencies, decision makers, and civil society; and establishing an integrated administration, management, and funding structure. We describe core program components, successes, and challenges to inform others seeking to improve health service delivery in a multidisciplinary and complex partnership.

Determinants of access to childhood cancer medicines: a comparative, mixed-methods analysis of four Caribbean countries.

BACKGROUND: Equitable access to essential medicines is a key facet of childhood cancer care, recognised by WHO as vital to improved childhood cancer outcomes globally. In the Caribbean, childhood cancer outcomes are poorer than those in most high-income countries. We aimed to generate in-depth comparative evidence of the current challenges and opportunities related to access to childhood cancer medicines in the Caribbean to identify context-sensitive health systems strategies to improve drug access and inform evidence-based paediatric cancer policies in the region. METHODS: In this convergent, parallel, mixed-methods study, we mapped and analysed the determinants of access to childhood cancer medicines in four Caribbean countries (The Bahamas, Barbados, Jamaica, and Trinidad and Tobago). We analysed contextual determinants of access to medicines within and across study site jurisdictions, alignment of childhood cancer medicine inclusion between each country's national essential medicines list (NEML) and WHO's 2017 Essential Medicines List for Children, and availability and cost of chemotherapeutic agents at five tertiary care hospitals. We used a mixed-effects logistic regression model to analyse the association of medicine price, procurement efficiency (via median price ratio [MPR]), and site with drug availability. The fixed effect evaluated the effect of site and MPR on the probability of stockout in a given month. We assessed determinants of medicine access via thematic analysis of semi-structured qualitative interviews, literature, and policy documents. FINDINGS: We collected and analysed data for 28 childhood cancer medicines from Barbados, 32 from The Bahamas, 30 from Trinidad and Tobago, and 31 from Jamaica. Despite stepwise inclusion of childhood cancer medicines in NEMLs, all four countries had frequent and recurrent stockouts for many cytotoxic medicines, showing no consistent relationship between NEML inclusion and availability. A mean MPR of greater than 3·0 in Trinidad and Tobago, The Bahamas, and Barbados suggests uniformly high procurement inefficiency, resulting in significant effects on drug stockout days. For each one unit increase in MPR the adjusted odds ratio (OR) of stockout increased by 10% (adjusted OR 1·10, 95% CI 1·04-1·16; p<0·01). These challenges in access to childhood cancer medicines stem from health system and policy dynamics at institutional, national, and supranational levels that cause price volatility and erratic medicine availability. Key challenges include disparate policy commitments (eg, among sites), inefficient procurement and supply chain management practices, and local effects of international market pressures. INTERPRETATION: The Caribbean region exemplifies deficiencies in access to childhood cancer medicines that might be overcome by improved regional harmonisation of drug registration, pharmacovigilance, and procurement alongside national forecasting to strengthen global pharmaceutical planning and prioritisation. Focused political attention to address these challenges is required to ensure efficient, reliable, and sustained availability of cancer mediciness. FUNDING: The SickKids-Caribbean Initiative.

Access to WHO Essential Medicines for Childhood Cancer Care in Trinidad and Tobago: A Health System Analysis of Barriers and Enablers.

PURPOSE: Improving access to essential medicines is necessary to reduce global mortality resulting from childhood cancer. However, there is a lack of context-specific data in many low- to middle-income countries on the determinants of access to essential childhood cancer medicines. We conducted a mixed-methods case study of the barriers to and enablers of access to WHO essential medicines for childhood cancer care in Trinidad and Tobago, in response to domestic calls for policy attention and reform. METHODS: We interviewed stakeholders (N = 9) across the pharmaceutical supply system using a novel analytic framework and qualitative interview guide. Interviews were recorded, transcribed, and analyzed with constant comparative methods to capture emergent themes. Quantitatively, we examined alignment of the national essential medicines list with the 2017 WHO Essential Medicines List for Children (EMLc). National buyer prices for EMLc cancer medicines were compared with median international prices, with calculation of median price ratios to assess procurement efficiency. RESULTS: Principal barriers identified included a lack of data-driven procurement, low supplier incentive to engage in tenders, reactive rather than proactive processes in response to stockouts, and siloed information systems. Recurring themes of regionalization, standardization, and proactivity emerged as priorities for policy reform. Quantitative analysis of the national essential medicines list and median price ratios for procured medicines aligned with findings reported qualitatively. CONCLUSION: Our study contributes to global efforts to improve childhood cancer care by identifying policy-relevant evidence on access to essential childhood cancer medicines and providing a model for future studies in other jurisdictions.

Advancing cancer care and prevention in the Caribbean: a survey of strategies for the region.

Cancer is now the second leading cause of death in the Caribbean. Despite this growing burden, many Caribbean small island nations have health systems that struggle to provide optimal cancer care for their populations. In this Series paper, we identify several promising strategies to improve cancer prevention and treatment that have emerged across small island nations that are part of the Caribbean Community. These strategies include the establishment of a Caribbean cancer registry hub, the development of resource-appropriate clinical guidelines, innovations in delivering specialty oncology services (eg, paediatric oncology and palliative care), improving access to opioids, and developing regional training capacity in palliative medicine. These developments emphasise the crucial role of public-private partnerships in improving health care for the region and show how fostering strategic collaborations with colleagues and centres in more developed countries, who can contribute specialised expertise and improve regional collaboration, can improve care across the cancer control continuum.

Oral health among children attending an oncology clinic in Trinidad.

Objectives: Little is known about the oral health of paediatric oncology patients in the Caribbean. Poor oral health can complicate oncology treatment, negatively affecting a child's health. In children undergoing chemotherapy or bone marrow transplant, odontogenic infections can progress to life-threatening sepsis. The aim of this study is to investigate the oral health among children attending an oncology clinic in Trinidad. Material and Methods: Sample population included paediatric oncology patients attending a children's hospital in Trinidad. Subsequent to obtaining informed consent, a 14-item questionnaire was administered to parents/caregivers. An intra-oral examination was undertaken by two dentists to assess soft tissues, gingival health, and dentition status, using visual examination only. Results: Seventy-one children and their caregivers participated in the study. The children consisted of both patients warded or attending as outpatients; 53.5% of patients were male and the mean age 6.64 (SD 3.33) years with a range of 1 to 15 years. Gingivitis and mucositis were present among 41.3% and 3% of patients, respectively. The prevalence of visible dental caries was 54.3%. Caries experience (dmft) was 2.28 (SD 3.63), and for those children with some caries experience (dmft > 0), this was 5.59 (SD 3.72). The majority (62.5%) had never visited a dentist. The most common dental treatment needs were dental prophylaxis (98.4%) and restorative treatment (50.8%). Acute lymphocytic leukaemia (39.1%) was the most common malignancy among this sample, and patients were at varying stages of cancer treatment. Conclusions: Oral health among this sample of paediatric oncology patients was generally poor, with untreated caries being common, and the majority of children not having had any previous dental care. Preventive dental care for these patients should include oral hygiene instruction, dietary advice, topical fluoride application along with management of carious lesions, and odontogenic infections. This preliminary study highlights the need for closer collaboration between general dental practitioners, paediatric dentists, and paediatric oncology physicians, in caring for these patients.

Bridging the Distance in the Caribbean: Telemedicine as a means to build capacity for care in paediatric cancer and blood disorders.

Over the past 50 years, survival for children in high-income countries has increased from 30% to over 80%, compared to 10-30% in low and middle income countries (LMIC). Given this gap in survival, established paediatric cancer treatment centres, such as The Hospital for Sick Children (SickKids) are well positioned to share clinical expertise. Through the SickKids Centre for Global Child Health, the SickKids-Caribbean Initiative (SCI) was launched in March 2013 to improve the outcomes and quality of life for children with cancer and blood disorders in the Caribbean. The six participating Caribbean countries are among those defined by the United Nations as Small Island Developing States, due to their small size, remote location and limited accessibility. Telemedicine presents an opportunity to increase their accessibility to health care services and has been used by SCI to facilitate two series of interprofessional rounds. Case Consultation Review Rounds are a forum for learning about diagnostic work-up, management challenges and treatment recommendations for these diseases. To date, 54 cases have been reviewed by SickKids staff, of which 35 have been presented in monthly rounds. Patient Care Education Rounds provide nurses and other staff with the knowledge base needed to safely care for children and adolescents receiving treatment. Five of these rounds have taken place to date, with over 200 attendees. Utilized by SCI for both clinical and non-clinical meetings, telemedicine has enhanced opportunities for collaboration within the Caribbean region. By building capacity and nurturing expert knowledge through education, SCI hopes to contribute to closing the gap in childhood survival between high and low-resource settings.
