Delays in Breast Cancer Presentation and Diagnosis at Two Rural Cancer Referral Centers in Rwanda

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.

Bringing cancer care to the poor: experiences from Rwanda.

The knowledge and tools to cure many cancer patients exist in developed countries but are unavailable to many who live in the developing world, resulting in unnecessary loss of life. Bringing cancer care to the poor, particularly to low-income countries, is a great challenge, but it is one that we believe can be met through partnerships, careful planning and a set of guiding principles. Alongside vaccinations, screening and other cancer-prevention efforts, treatment must be a central component of any cancer programme from the start. It is also critical that these programmes include implementation research to determine programmatic efficacy, where gaps in care still exist and where improvements can be made. This article discusses these issues using the example of Rwandas expanding national cancer programme.

Enhancing formal educational and in-service training programs in rural Rwanda: a partnership among the public sector, a nongovernmental organization, and academia.

Global disparities in the distribution, specialization, diversity, and competency of the health workforce are striking. Countries with fewer health professionals have poorer health outcomes compared with countries that have more. Despite major gains in health indicators, Rwanda still suffers from a severe shortage of health professionals. This article describes a partnership launched in 2005 by Rwanda’s Ministry of Health with the U.S. nongovernmental organization Partners In Health and with Harvard Medical School and Brigham and Women’s Hospital. The partnership has expanded to include the Faculty of Medicine and the School of Public Health at the National University of Rwanda and other Harvard-affiliated academic medical centers. The partnership prioritizes local ownership and—with the ultimate goals of strengthening health service delivery and achieving health equity for poor and underserved populations—it has helped establish new or strengthen existing formal educational programs (conferring advanced degrees) and in-service training programs (fostering continuing professional development) targeting the local health workforce. Harvard Medical School and Brigham and Women’s Hospital have also benefited from the partnership, expanding the opportunities for training and research in global health available to their faculty and trainees. The partnership has enabled Rwandan health professionals at partnership-supported district hospitals to acquire new competencies and deliver better health services to rural and underserved populations by leveraging resources, expertise, and growing interest in global health within the participating U.S. academic institutions. Best practices implemented during the partnership’s first nine years can inform similar formal educational and in-service training programs in other low-income countries.

Diagnosis of cancer in rural Rwanda: early outcomes of a phased approach to implement anatomic pathology services in resource-limited settings.

OBJECTIVES Adequate pathology services are a prerequisite to accurate cancer diagnoses and tailoring appropriate treatment. Limitations in skilled personnel and infrastructure are among the challenges faced by developing countries. We describe a stepwise implementation of anatomic pathology laboratory services at Butaro District Hospital, designated as a Cancer Center of Excellence in rural Rwanda. METHODS The phased approach to developing pathology services up to December 2012 is described. A retrospective review of specimens submitted to Butaro District Hospital between July 1, 2012, and December 31, 2012, was conducted. Patient clinical characteristics and sociodemographics are also described. RESULTS During the study period, a total of 437 tissue specimens were submitted. Among these, 143 (32.7%) were from male patients, 244 (55.8%) were confirmed as malignant, 163 (37.3%) were benign, 28 (6.4%) were inconclusive, and two (0.5%) results were not available at the time of analysis. The median time from specimen receipt at Butaro to final reporting was 32 days (range, 7-193 days; interquartile range, 23-44 days). CONCLUSIONS Our experience demonstrates that anatomic pathology services can be established in resource-limited settings and local capacity can be built to support accurate diagnoses. Our approach included leveraging partnerships, volunteer experts, and task shifting and will be expanded to include telepathology.

Implementation and Validation of Telepathology Triage at Cancer Referral Center in Rural Rwanda

Purpose Connecting a cancer patient to the appropriate treatment requires the correct diagnosis provided in a timely manner. In resource-limited settings, the anatomic pathology bridge to efficient, accurate, and timely cancer care is often challenging. In this study, we present the first phase of an anatomic telepathology triage system, which was implemented and validated at the Butaro District Hospital in northern rural Rwanda. Methods Select cases over a 9-month period in three segments were evaluated by static image telepathology and were independently evaluated by standard glass slide histology. Each case via telepathology was classified as malignant, benign, infectious/inflammatory, or nondiagnostic and was given an exact histologic diagnosis. Results For cases triaged as appropriate for telepathology, correlation with classification and exact diagnosis demonstrated greater than 95% agreement over the study. Cases in which there was disagreement were analyzed for cause, and the triage process was adjusted to avoid future problems. Conclusion Challenges to obtaining a correct and complete diagnosis with telepathology alone included the need for immunohistochemistry, assessment of the quality of images, and the lack of images representing an entire sample. The next phase of the system will assess the effect of telepathology triage on turnaround time and the value of on-site immunohistochemistry in reducing that metric and the need for evaluation outside of telepathology.

Caring for patients with surgically resectable cancers: experience from a specialised centre in rural Rwanda

SETTING Butaro Cancer Centre of Excellence (BCCOE), Burera District, Rwanda. OBJECTIVES To describe characteristics, management and 6-month outcome of adult patients presenting with potentially surgically resectable cancers. DESIGN Retrospective cohort study of patients presenting between 1 July and 31 December 2012. RESULTS Of 278 patients, 76.6% were female, 51.4% were aged 50-74 years and 75% were referred from other district or tertiary hospitals in Rwanda. For the 250 patients with treatment details, 115 (46%) underwent surgery, with or without chemotherapy/radiotherapy. Median time from admission to surgery was 21 days (IQR 2-91). Breast cancer was the most common type of cancer treated at BCCOE, while other forms of cancer (cervical, colorectal and head and neck) were mainly operated on in tertiary facilities. Ninety-nine patients had no treatment; 52% of these were referred out within 6 months, primarily for palliative care. At 6 months, 6.8% had died or were lost to follow-up. CONCLUSION Surgical care was provided for many cancer patients referred to BCCOE. However, challenges such as inadequate surgical infrastructure and skills, and patients presenting late with advanced and unresectable disease can limit the ability to manage all cases. This study highlights opportunities and challenges in cancer care relevant to other hospitals in rural settings.

Benign and Malignant Breast Disease at Rwanda’s First Public Cancer Referral Center

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.

Implementation Science for Global Oncology: The Imperative to Evaluate the Safety and Efficacy of Cancer Care Delivery

PURPOSE The development of cancer care treatment facilities in resource-constrained settings represents a challenge for many reasons. Implementation science-the assessment of how services are set up and delivered; contextual factors that affect delivery, treatment safety, toxicity, and efficacy; and where adaptations are needed-is essential if we are to understand the performance of a treatment program, know where the gaps in care exist, and design interventions in care delivery models to improve outcomes for patients. METHODS The field of implementation science in relation to cancer care delivery is reviewed, and the experiences of the integrated implementation science program at the Butaro Cancer Center of Excellence in Rwanda are described as a practical application. Implementation science of HIV and tuberculosis care delivery in similar challenging settings offers some relevant lessons. RESULTS Integrating effective implementation science into cancer care in resource-constrained settings presents many challenges, which are discussed. However, with carefully designed programs, it is possible to perform this type of research, on regular and ongoing bases, and to use the results to develop interventions to improve quality of care and patient outcomes and provide evidence for effective replication and scale-up. CONCLUSION Implementation science is both critical and feasible in evaluating, improving, and supporting effective expansion of cancer care in resource-limited settings. In ideal circumstances, it should be a prospective program, established early in the lifecycle of a new cancer treatment program and should be an integrated and continual process.

Validation of a community-based survey assessing nonobstetric surgical conditions in Burera District, Rwanda

BACKGROUND Validated, community-based surveillance methods to monitor epidemiologic progress in surgery have not yet been employed for surgical capacity building. The goal of this study was to create and assess the validity of a community-based questionnaire collecting data on untreated surgically correctable disease throughout Burera District, Rwanda, to accurately plan for surgical services at a district hospital. METHODS A structured interview to assess for 10 index surgically treatable conditions was created and underwent local focus group and pilot testing. Using a 2-stage cluster sampling design, Rwandan data collectors conducted the structured interview in 30 villages throughout the Burera District. Rwandan physicians revisited the surveyed households to perform physical examinations on all household members, used as the gold standard to validate the structured interview. RESULTS A total of 2,990 individuals were surveyed and 2,094 (70%) were available for physical examination. The calculated sensitivity and specificity of the survey tool were 44.5% (95% CI, 38.9-50.2%) and 97.7% (95% CI, 96.9-98.3%), respectively. The conditions with the highest sensitivity and specificity were hydrocephalus, clubfoot, and injuries/infections. Injuries/infections and hernias/hydroceles were the conditions most frequently found on examination that were not reported during the interview. CONCLUSION This study provides the first attempt to validate a community-based surgical surveillance tool. The finding of low sensitivity was likely related to limited access to care and poor health literacy. Accurate community-based surveys are critical to planning integrated health systems that include surgical care as a core component.

Epidemiology of untreated non-obstetric surgical disease in Burera District, Rwanda: a cross-sectional survey

BACKGROUND In low-income and middle-income countries, surgical epidemiology is largely undefined at the population level, with operative logs and hospital records serving as a proxy. This study assesses the distribution of surgical conditions that contribute the largest burden of surgical disease in Burera District, in northern Rwanda. We hypothesise that our results would yield higher rates of surgical disease than current estimates (from 2006) for similar low-income countries, which are 295 per 100 000 people. METHODS In March and May, 2012, we performed a cross-sectional study in Burera District, randomly sampling 30 villages with probability proportionate to size and randomly sampling 23 households within the selected villages. Six Rwandan surgical postgraduates and physicians conducted physical examinations on all eligible participants in sampled households. Participants were assessed for injuries or wounds, hernias, hydroceles, breast mass, neck mass, obstetric fistula, undescended testes, hypospadias, hydrocephalus, cleft lip or palate, and club foot. Ethical approval was obtained from Boston Childrens Hospital (Boston, MA, USA) and the Rwandan National Ethics Committee (Kigali, Rwanda). Informed consent was obtained from all participants. FINDINGS Of the 2165 examined individuals, the overall prevalence of any surgical condition was 12% (95% CI 9·2-14·9) or 12 009 per 100 000 people. Injuries or wounds accounted for 55% of the prevalence and hernias or hydroceles accounted for 40%, followed by neck mass (4·2%), undescended testes (1·9%), breast mass (1·2%), club foot (1%), hypospadias (0·6%), hydrocephalus (0·6%), cleft lip or palate (0%), and obstetric fistula (0%). When comparing study participant characteristics, no statistical difference in overall prevalence was noted when examining sex, wealth, education, and travel time to the nearest hospital. Total rates of surgically treatable disease yielded a statistically significant difference compared with current estimates (p<0·001). INTERPRETATION Rates of surgically treatable disease are significantly higher than previous estimates in comparable low-income countries. The prevalence of surgically treatable disease is evenly distributed across demographic parameters. From these results, we conclude that strengthening the Rwandan health systems surgical capacity, particularly in rural areas, could have meaningful affect on the entire population. Further community-based surgical epidemiological studies are needed in low-income and middle-income countries to provide the best data available for health system planning.
