Outcomes of Low-Intensity Treatment of Acute Lymphoblastic Leukemia at Butaro Cancer Center of Excellence in Rwanda.

PURPOSE: Children with acute lymphoblastic leukemia (ALL) in low-income countries have disproportionately lower cure rates than those in high-income countries. At Butaro Cancer Center of Excellence (BCCOE), physicians treated patients with ALL with the first arm of the Hunger Protocol, a graduated-intensity method tailored for resource-limited settings. This article provides the first published outcomes, to our knowledge, of patients with ALL treated with this protocol. METHODS: This is a retrospective descriptive study of patients with ALL enrolled at BCCOE from July 1, 2012 to June 30, 2014; data were collected through December 31, 2015. Descriptive statistics were used to calculate patient demographics, disease characteristics, and outcomes; event-free survival was assessed at 2 years using the Kaplan-Meier method. RESULTS: Forty-two consecutive patients with ALL were included. At the end of the study period, 19% (eight) were alive without evidence of relapse: three completed treatment and five were continuing treatment. Among the remaining patients, 71% (30) had died and 10% (four) were lost to follow-up. A total of 83% (25) of the deaths were disease related, 3% (one) treatment-related, and 13% (four) unclear. Event-free survival was 22% (95% CI, 11% to 36%), considering lost to follow-up as an event, and 26% (95% CI, 13% to 41%) if lost to follow-up is censored. CONCLUSION: As expected, relapse was the major cause of failure with this low-intensity regimen. However, toxicity was acceptably low, and BCCOE has decided to advance to intensity level 2. These results reflect the necessity of a data-driven approach and a continual improvement process to care for complex patients in resource-constrained settings.

Voices of Hope From Rural Rwanda: Three Oncology Nurse Leaders Emerge.

The cancer burden in low- and middle-income countries (LMICs) has been well described in the literature (International Agency for Research on Cancer, 2012; Ott, Ullrich, Mascarenhas, & Stevens, 2011; Thun, DeLancey, Center, Jemal, & Ward, 2010). According to the World Health Organization ([WHO], 2015), about 14 million new cancer cases occurred in 2012, and more than 60% of those cases were in Africa, Asia, and Central and South America; of the 8.2 million cancer-related deaths in 2012, more than 70% occurred in these regions (Bray & Møller, 2006).

Pursuing equity in cancer care: implementation, challenges and preliminary findings of a public cancer referral center in rural Rwanda.

BACKGROUND: Cancer services are inaccessible in many low-income countries, and few published examples describe oncology programs within the public sector. In 2011, the Rwanda Ministry of Health (RMOH) established Butaro Cancer Center of Excellence (BCCOE) to expand cancer services nationally. In hopes of informing cancer care delivery in similar settings, we describe program-level experience implementing BCCOE, patient characteristics, and challenges encountered. METHODS: Butaro Cancer Center of Excellence was founded on diverse partnerships that emphasize capacity building. Services available include pathology-based diagnosis, basic imaging, chemotherapy, surgery, referral for radiotherapy, palliative care and socioeconomic access supports. Retrospective review of electronic medical records (EMR) of patients enrolled between July 1, 2012 and June 30, 2014 was conducted, supplemented by manual review of paper charts and programmatic records. RESULTS: In the program's first 2 years, 2326 patients presented for cancer-related care. Of these, 70.5% were female, 4.3% children, and 74.3% on public health insurance. In the first year, 66.3% (n = 1144) were diagnosed with cancer. Leading adult diagnoses were breast, cervical, and skin cancer. Among children, nephroblastoma, acute lymphoblastic leukemia, and Hodgkin lymphoma were predominant. As of June 30, 2013, 95 cancer patients had died. Challenges encountered include documentation gaps and staff shortages. CONCLUSION: Butaro Cancer Center of Excellence demonstrates that complex cancer care can be delivered in the most resource-constrained settings, accessible to vulnerable patients. Key attributes that have made BCCOE possible are: meaningful North-south partnerships, innovative task- and infrastructure-shifting, RMOH leadership, and an equity-driven agenda. Going forward, we will apply our experiences and lessons learned to further strengthen BCCOE, and employ the developed EMR system as a valuable platform to assess long-term clinical outcomes and improve care.

Treating Nephroblastoma in Rwanda: Using International Society of Pediatric Oncology Guidelines in a Novel Oncologic Care Model.

PURPOSE: Success in treating nephroblastoma in high-income countries has been transferred to some resource-constrained settings; multicenter studies report disease-free survival of greater than 70%. However, few reports present care models with rural-based components, care tasks shifted to internists and pediatricians, and data collection structured for monitoring and evaluation. Here, we report clinical outcomes and protocol compliance for patients with nephroblastoma evaluated at Butaro Cancer Center of Excellence in Rwanda. PATIENTS AND METHODS: This retrospective study reports the care of 53 patients evaluated between July 1, 2012, and June 30, 2014. Patients receiving less than half of their chemotherapy at Butaro Cancer Center of Excellence were excluded. RESULTS: Of the 53 patients included, 9.4% had stage I, 13.2% had stage II, 24.5% had stage III, 26.4% had stage IV, and 5.7% had stage V disease; the remaining 20.8% had unknown stage disease from inadequate work-up or unavailable surgical report. The incidence of neutropenia increased with treatment progression, and the greatest proportion of delays occurred during the surgical referral phase. At the end of the study period, 32.1% of patients (n = 17) remained alive after treatment; 24.5% (n = 13) remained alive while continuing treatment, including one patient with recurrent disease; 30.2% (n = 16) died; and 13.2% (n = 7) were lost to follow-up. CONCLUSION: Our findings confirm that nephroblastoma can be effectively treated in resource-constrained settings. Using an approach in which chemotherapy is delivered at a rural-based center by nononcologists and data are used for routine evaluation, care can be delivered in safe, novel ways. Protocol modifications to mitigate chemotherapy toxicities and strong communication between the multidisciplinary team members will likely minimize delays and further improve outcomes in similar settings.

Gestational Trophoblastic Neoplasia Treatment at the Butaro Cancer Center of Excellence in Rwanda.

PURPOSE: Gestational trophoblastic neoplasia (GTN) is a highly treatable disease, most often affecting young women of childbearing age. This study reviewed patients managed for GTN at the Butaro Cancer Center of Excellence (BCCOE) in Rwanda to determine initial program outcomes. PATIENTS AND METHODS: A retrospective medical record review was performed for 35 patients with GTN assessed or treated between May 1, 2012, and November 30, 2014. Stage, risk score, and low or high GTN risk category were based on International Federation of Gynecology and Obstetrics staging and the WHO scoring system and determined by beta human chorionic gonadotropin level, chest x-ray, and ultrasound per protocol guidelines for resource-limited settings. Pathology reports and computed tomography scans were assessed when possible. Treatment was based on a predetermined protocol stratified by risk status. RESULTS: Of the 35 patients (mean age, 32 years), 26 (74%) had high-risk and nine (26%) had low-risk disease. Nineteen patients (54%) had undergone dilation and curettage and 11 (31%) had undergone hysterectomy before evaluation at BCCOE. Pathology reports were available in 48% of the molar pregnancy surgical cases. Systemic chemotherapy was initiated in 30 of the initial 35 patients: 13 (43%) received single-agent oral methotrexate, 15 (50%) received EMACO (etoposide, methotrexate, dactinomycin, cyclophosphamide, and vincristine), and two (7%) received alternate regimens. Of the 13 patients initiating methotrexate, three had their treatment intensified to EMACO. Four patients experienced treatment delays because of medication stockouts. At a median follow-up of 7.8 months, the survival probability for low-risk patients was 1.00; for high-risk patients, it was 0.63. CONCLUSION: This experience demonstrates the feasibility of GTN treatment in rural, resource-limited settings. GTN is a curable disease and can be treated following the BCCOE model of cancer care.
