BACKGROUND Breast cancer incidence is increasing in low- and middle-income countries (LMICs). Mortality/incidence ratios in LMICs are higher than in high-income countries, likely at least in part because of delayed diagnoses leading to advanced-stage presentations. In the present study, we investigated the magnitude, impact of, and risk factors for, patient and system delays in breast cancer diagnosis in Rwanda. MATERIALS AND METHODS We interviewed patients with breast complaints at two rural Rwandan hospitals providing cancer care and reviewed their medical records to determine the diagnosis, diagnosis date, and breast cancer stage. RESULTS A total of 144 patients were included in our analysis. Median total delay was 15 months, and median patient and system delays were both 5 months. In multivariate analyses, patient and system delays of ≥6 months were significantly associated with more advanced-stage disease. Adjusting for other social, demographic, and clinical characteristics, a low level of education and seeing a traditional healer first were significantly associated with a longer patient delay. Having made ≥5 health facility visits before the diagnosis was significantly associated with a longer system delay. However, being from the same district as one of the two hospitals was associated with a decreased likelihood of system delay. CONCLUSION Patients with breast cancer in Rwanda experience long patient and system delays before diagnosis; these delays increase the likelihood of more advanced-stage presentations. Educating communities and healthcare providers about breast cancer and facilitating expedited referrals could potentially reduce delays and hence mortality from breast cancer in Rwanda and similar settings. IMPLICATIONS FOR PRACTICE Breast cancer rates are increasing in low- and middle-income countries, and case fatality rates are high, in part because of delayed diagnosis and treatment. This study examined the delays experienced by patients with breast cancer at two rural Rwandan cancer facilities. Both patient delays (the interval between symptom development and the patients first presentation to a healthcare provider) and system delays (the interval between the first presentation and diagnosis) were long. The total delays were the longest reported in published studies. Longer delays were associated with more advanced-stage disease. These findings suggest that an opportunity exists to reduce breast cancer mortality in Rwanda by addressing barriers in the community and healthcare system to promote earlier detection.

BACKGROUND Breast cancer incidence is rising in low- and middle-income countries. Understanding the distribution of breast disease seen in clinical practice in such settings can guide early detection efforts and clinical algorithms, as well as support future monitoring of cancer detection rates and stage. PATIENTS AND METHODS We conducted a retrospective medical record review of 353 patients who presented to Butaro Cancer Center of Excellence in Rwanda with an undiagnosed breast concern during the first 18 months of the cancer program. RESULTS Eighty-two percent of patients presented with a breast mass. Of these, 55% were diagnosed with breast cancer and 36% were diagnosed with benign disease. Cancer rates were highest among women 50 years and older. Among all patients diagnosed with breast cancer, 20% had stage I or II disease at diagnosis, 46% had locally advanced (stage III) disease, and 31% had metastatic disease. CONCLUSION After the launch of Rwandas first public cancer referral center and breast clinic, cancer detection rates were high among patients presenting with an undiagnosed breast concern. These findings will provide initial data to allow monitoring of changes in the distribution of benign and malignant disease and of cancer stage as cancer awareness and services expand nationally. IMPLICATIONS FOR PRACTICE The numbers of cases and deaths from breast cancer are rising in low-income countries. In many of these settings, health care systems to address breast problems and efficiently refer patients with symptoms concerning for cancer are rudimentary. Understanding the distribution of breast disease seen in such settings can guide early detection efforts and clinical algorithms. This study describes the characteristics of patients who came with a breast concern to Rwandas first public cancer referral center during its first 18 months. More than half of patients with a breast mass were diagnosed with cancer; most had late-stage disease. Monitoring changes in the types of breast disease and cancer stages seen in Rwanda will be critical as breast cancer awareness and services grow.

Purpose The burden of cancer is rising in low- and middle-income countries, yet cancer treatment requires resources that are often not available in these settings. Although management of chronic myeloid leukemia (CML) has been described in low- and middle-income countries, few programs involve patients treated in rural settings. We describe characteristics and early outcomes of patients treated for CML at rural district hospitals in Rwanda. Methods We conducted a retrospective review of patients with confirmed BCR-ABL–positive CML who were enrolled between July 1, 2009 and June 30, 2014. Types of data included patient demographics, diagnostic work up, treatment, clinical examination, laboratory testing, and death. Results Forty-three patients were included, with a maximum follow-up of 58 months. Of 31 patients who were imatinib-naïve at enrollment, 54.8% were men and the median age at diagnosis was 36.9 years (interquartile range: 29-42 years). Approximately two-thirds of patients (67.7%) were on the national public insurance scheme. The imatinib dose was reduced for 16 patients and discontinued for five. Thirty-two of the 43 patients continued to have normal blood counts at last follow-up. Four patients have died and four are lost to follow-up. Conclusion Our experience indicates that CML can be effectively managed in a resource-constrained rural setting, despite limited availability of on-site diagnostic resources or specialty oncology personnel. The importance of model public-private partnerships as a strategy to bring high-cost, life-saving treatment to people who do not have the ability to pay is also highlighted.

Background. More than 85% of pediatric cancer cases and 95% of deaths occur in resource‐poor countries that use less than 5% of the worlds health resources. In the developed world, approximately 81% of children with cancer can be cured. Models applicable in the most resource‐poor settings are needed to address global inequities in pediatric cancer treatment. Procedure. Between 2006 and 2011, a cohort of children received cancer therapy using a new approach in rural Rwanda. Children were managed by a team of a Rwandan generalist doctor, Rwandan nurse case manager, Rwanda‐based US‐trained pediatrician, and US‐based pediatric oncologist. Biopsies and staging studies were obtained in‐country. Pathologic diagnoses were made at US or European laboratories. Rwanda‐based clinicians and the pediatric oncologist jointly generated treatment plans by telephone and email. Results. Treatment was provided to 24 patients. Diagnoses included lymphomas (n = 10), sarcomas (n = 9), leukemias (n = 2), and other malignancies (n = 3). Standard chemotherapy regimens included CHOP, ABVD, VA, COP/COMP, and actino‐VAC. Thirteen patients were in remission at the completion of data collection. Two succumbed to treatment complications and nine had progressive disease. There were no patients who abandoned treatment. The mean overall survival was 31 months and mean disease‐free survival was 18 months. Conclusions. These data suggest that chemotherapy can be administered with curative intent to a subset of cancer patients in this setting. This approach provides a platform for pediatric cancer care models, relying on local physicians collaborating with remote specialist consultants to deliver subspecialty care in resource‐poor settings.

Purpose Low- and middle-income countries disproportionately comprise 65% of cancer deaths. Cancer care delivery in resource-limited settings, especially low-income countries in sub-Saharan Africa, is exceedingly complex, requiring multiple modalities of diagnosis and treatment. Given the vast human, technical, and financial resources required, access to radiotherapy remains limited in sub-Saharan Africa. Through 2017, Rwanda has not had in-country radiotherapy services. The aim of this study was to describe the implementation and early outcomes of the radiotherapy referral program at the Butaro Cancer Centre of Excellence and to identify both successful pathways and barriers to care. Methods Butaro District Hospital is located in a rural area of the Northern Province and is home to the Butaro Cancer Centre of Excellence. We performed a retrospective study from routinely collected data of all patients with a diagnosis of cervical, head and neck, or rectal cancer between July 2012 and June 2015. Results Between 2012 and 2015, 580 patients were identified with these diagnoses and were potential candidates for radiation. Two hundred eight (36%) were referred for radiotherapy treatment in Uganda. Of those referred, 160 (77%) had cervical cancer, 31 (15%) had head and neck cancer, and 17 (8%) had rectal cancer. At the time of data collection, 101 radiotherapy patients (49%) were alive and had completed treatment with no evidence of recurrence, 11 (5%) were alive and continuing treatment, and 12 (6%) were alive and had completed treatment with evidence of recurrence. Conclusion This study demonstrates the feasibility of a rural cancer facility to successfully conduct out-of-country radiotherapy referrals with promising early outcomes. The results of this study also highlight the many challenges and lessons learned in providing comprehensive cancer care in resource-limited settings.

Purpose In April 2015, we initiated a training program to facilitate earlier diagnosis of breast cancer among women with breast symptoms in rural Rwanda. The goal of this study was to assess the impact of the training intervention in breast cancer detection on knowledge and skills among health center nurses and community health workers (CHWs). Methods We assessed nurses’ and CHWs’ knowledge about breast cancer risk factors, signs and symptoms, and treatability through a written test administered immediately before, immediately after, and 3 months after trainings. We assessed nurses’ skills in clinical breast examination immediately before and after trainings and then during ongoing mentorship by a nurse midwife. We also examined the appropriateness of referrals made to the hospital by health center nurses. Results Nurses’ and CHWs’ written test scores improved substantially after the trainings (overall percentage correct increased from 73.9% to 91.3% among nurses and from 75.0% to 93.8% among CHWs (P < .001 for both), and this improvement was sustained 3 months after the trainings. On checklists that assessed skills, nurses’ median percentage of actions performed correctly was 24% before the training. Nurses’ skills improved significantly after the training and were maintained during the mentorship period (the median score was 88% after training and during mentorship; P < .001). In total, 96.1% of patients seen for breast concerns at the project’s hospital-based clinic were deemed to have been appropriately referred. Conclusion Nurses and CHWs demonstrated substantially improved knowledge about breast cancer and skills in evaluating and managing breast concerns after brief trainings. With adequate training, mentorship, and established care delivery and referral systems, primary health care providers in sub-Saharan Africa can play a critical role in earlier detection of breast cancer.

Abstract 34Background:While Hodgkin lymphoma (HL) is highly curable with standard chemotherapy in high resource settings, there are few reports of HL treatment in low resource settings. In Rwanda, a treatment protocol using six cycles of ABVD chemotherapy (doxorubicin, bleomycin, vinblastine, dacarbazine) without radiotherapy has been implemented at two rural district hospitals. Here we report on the feasibility of this approach, our patient characteristics, and preliminary outcomes.Methods:We conducted a retrospective cohort study of all patients with biopsy confirmed HL seen at Butaro and Rwinkwavu hospitals between June 2012 and August 2015. Data was extracted from clinical charts and analyzed using descriptive statistics.Results:43 HL patients were seen at Butaro (n=38) and Rwinkwavu (n=5); 58% male, median age 17 (range 4-54). Five (12%) were HIV positive. Of 22 patients with biopsy specimens evaluated for EBV, 12 (55%) were positive, 9 (41%) negative, and one indeterminate. Most patients were staged...
