Purpose Data quality is a core value of cancer registries, which bring about greater understanding of cancer distribution and determinants. Thailand established its cancer registry in 1986; however, studies focusing on data reliability have been limited. This study aimed to assess the coding completeness and reliability of the National Cancer Institute (NCI) hospital-based cancer registry, Thailand. Methods This study was conducted using the reabstracting method. We focused on seven cancer sites—the colon, rectum, liver, lung, breast, cervix, and prostate—registered between 2012 and 2014 in the NCI hospital-based cancer registry. Missing data were identified for coding completeness calculation among important variables. The agreement rate and κ coefficient were computed to represent data reliability. Results For reabstracting, we retrieved 957 medical records from a total of 5,462. These were selected using the probability proportional to size method, stratified by topology, sex, and registered year. The overall coding completeness of the registered and reabstracted data was 89.9% and 93.6%, respectively. In addition, the overall agreement rate among variables ranged from 84.7% to 99.6%, and κ coefficient ranged from 0.619 to 0.995. The misclassification among unilateral organs caused lower coding completeness and agreement rate of laterality coding. The completeness of current residency could be improved using the reabstracting method. The lowest agreement rate was found among various categories of diagnosis basis. Sex misclassification for male breast cancer was identified. Conclusion The coding completeness and data reliability of the NCI hospital-based cancer registry met the standard in most critical variables. However, some challenges remain to improve the data quality. The reabstracting method could identify the critical points affecting the quality of cancer registry data.

Abstract 69 Background: One of the challenges to addressing the growing burden of cancer in low- and middle-income countries is insufficient data and limitations in quality of cancer registries. The Botswana National Cancer Registry (BNCR), first established in 1999, is an IARC-endorsed population-based registry covering a population of 2.1 million. Here we assess BNCR's data quality over time. Methods: We conducted a retrospective review of BNCR data that was collected between January 1, 2005 and December 31, 2010. We assessed basis of cancer diagnosis, as well as key data quality indices (completeness, consistency, uniqueness, and accuracy) over two time periods: 2005–2007 and 2008–2010. We assessed cancer incidence and distribution during this time period, and reviewed Botswana Ministry of Health operational documents to identify major health care initiatives that may have had a bearing on cancer registry data quality. Results: In total, 8,938 cancer cases were registered 2005-2010. Kaposi sarcoma was the most commonly diagnosed cancer (n=1766, 19.4%), followed by cervical cancer (n=1252, 13.8%) and then breast cancer (n=801, 8.8%). During 2005-2007, 79% of all cancers were morphologically verified and 6% of were verified by death certificate alone. By 2008-2010, 89% of cancers were morphologically verified while none (0%) were verified by death certificate alone. There was a marked difference for basis of Kaposi sarcoma diagnosis (26% in 2005-2007, 43.8% 2008-2010), which changed from mainly clinical to pathology-based diagnosis. Factors that have contributed to this improvement include targeted initiatives such as clinician training, as well as broader health system developments such as general laboratory diagnostic capacitation that has facilitated use of histopathology services for cancer. Conclusion: BNCR data quality has improved over the years. These improvements enhance utility of cancer registry data for healthcare planning, and highlight the merit of cross-cutting health systems strengthening developments. This assessment, and the initiatives that have contributed to BNCR data improvement may be relevant to cancer registries in similar settings.

Background: Breast cancer was the most common cancer in the world. GLOBOCAN 2012 estimated the incidence of female breast cancer in Indonesia was 40.3 per 100,000 and the mortality rate was 16.6 per 100,000. In 2016, Dharmais National Cancer Center was appointed as Regional Population Based Cancer Registry in West Jakarta. West Jakarta was a municipality with 2,281,945 populations, being the 2nd largest population in DKI Jakarta Province. Aim: This study was to evaluate the quality of population based cancer registry data and to describe the epidemiology of female breast cancer in West Jakarta, Indonesia during 2008-2012 and to compare with GLOBOCAN 2012 . Methods: We used population based cancer registry data with ICD - O code C50.0-C50.9 in female who live in West Jakarta. The population based cancer registry data were collected in Dharmais National Cancer Center. We evaluated the quality of population based cancer registry data based on WHO-IARC rules for cancer registry data. Results: The quality of population based cancer registry data were microscopic verification (70%); DCO percentage (20.8%), and unknown age (0%). The trend of female breast cancer was increasing during 2008-2012. Age-standardized rate incidence was 19.3 per 100,000. The most of frequent were in 45-49 years old, not other specific location subtopography (81.5%), the histopathology type was ductal and lobular neoplasm (51.8%), in stage III (44%), and with metastases to bone (34%). The average of length of duration was 29.1 months, most of them were unknown of last status contact (84%). Conclusion: The coverage and quality data of West Jakarta population based cancer registry need to be increased and establish a follow-up system to decrease the unknown last contact status of patients.

6523 Background: The value of linking population-based cancer registry data with insurance claims files to assess quality of care has been demonstrated in numerous studies, including those using NCI’s linked SEER-Medicare database, covering patients age 65+ in fee-for-service plans, and studies linking registry data with Medicaid, private insurance, or managed care data covering the under-65 population. We describe a prototype program linking registry data with multiple data sources to assess quality of care for at-risk populations in a defined geographical area. Methods: Data exchange agreements were executed among the investigative site (Emory University), Georgia state government, and the claims data sources/vendors. We linked Georgia Cancer Registry (GCR) records for 1999-2005 incident cases of breast and colorectal cancer with enrollment and medical services records from Medicare, Medicaid, Kaiser Permanente of Georgia, and the State Health Benefit Plan (SHBP) which covers all state workers and dependents. Following data quality checks, algorithms based on National Quality Forum (NQF) endorsed breast and colorectal cancer quality measures were applied to each linked data set to assess performance. Results: The linked data sets included 60% of all breast and colorectal cancer cases in the GCR over the study period. Quality measure performance rates varied notably across payers. For example, the percent of Stage III colon cancer patients meeting the NQF standard for adjuvant chemotherapy in the linked GCR-Medicaid, GCR-Kaiser, and GCR-SHBP data were, respectively, 75%, 92%, and 92% (p<0.05). The rates for breast cancer patients meeting standards for adjuvant chemotherapy were 86%, 84%, and 87% (p=NS), respectively. Patients in the linked GCR-Medicare data (all age 65+) generally had lower performance rates for each NQF measure. Conclusions: Linking state cancer registry data with multiple public and private sources of administrative data is technically feasible, and may represent a viable strategy for building a national cancer data system for quality improvement, as recommended in 1999 by the Institute of Medicine.

PURPOSE To audit and improve the completeness of the hierarchic (or is-a) relations of the National Cancer Institute (NCI) Thesaurus to support its role as a faceted system for querying cancer registry data. METHODS We performed quality auditing of the 19.01d version of the NCI Thesaurus. Our hybrid auditing method consisted of three main steps: computing nonlattice subgraphs, constructing lexical features for concepts in each subgraph, and performing subsumption reasoning with each subgraph to automatically suggest potentially missing is-a relations. RESULTS A total of 9,512 nonlattice subgraphs were obtained. Our method identified 925 potentially missing is-a relations in 441 nonlattice subgraphs; 72 of 176 reviewed samples were confirmed as valid missing is-a relations and have been incorporated in the newer versions of the NCI Thesaurus. CONCLUSION Autosuggested changes resulting from our auditing method can improve the structural organization of the NCI Thesaurus in supporting its new role for faceted query.

Background A hospital-based cancer registry can be used as a guide to decision-making. Considering the limited cancer registry data in the population, the Yogyakarta Pediatric Cancer Registry (YPCR) is one of the pioneers of hospital-based pediatric cancer registries in Indonesia. The YPCR was started in 2000 in Dr. Sardjito Hospital. Objective To describe the characteristics of childhood cancer and the outcomes by analyzing overall survival (OS) and event-free survival (EFS) based on data from Yogyakarta Pediatric Cancer Registry. Methods Data were collected from the YPCR for the period of 2000 to 2016. Childhood cancers were classified into 12 groups based on the 3rd edition International Classification for Childhood Cancer (ICCC). Incidence, frequency, and distribution of cases were grouped by sex, age, and patients’ place of residence. Incidence was further analyzed using SPSS software. Kaplan-Meier test was used to analyze OS and EFS. Results Within the study period, 2,441 children aged 0-18 years were diagnosed with cancer. The highest incidence was found in the 1-5-year age group. The most common diagnoses found were leukemia, myeloproliferative disorders, and myelodysplastic disease (58%); lymphoma and reticuloendothelial neoplasm (8%); retinoblastoma (6%); soft tissue and other extra-osseous sarcomas (5%); as well as neuroblastoma and other peripheral nervous cell tumors (5%). The OSs of acute lymphoblastic leukemia (ALL), high risk ALL (HR-ALL), and standard risk (SR-ALL) were 31.8%, 18.5%, and 43.9%, respectively. The EFSs of ALL, HR-ALL, and SR-ALL were 23.9%, 14.7%, and 32.4%, respectively. For solid tumors, the OS was 13.7% and EFS was 6.4%. Conclusion The number of new cases of childhood cancer has increased in the last few years. The Yogyakarta Pediatric Cancer Registry (YPCR), which serves as a hospital-based pediatric cancer registry, has an important role to evaluate clinical and non-clinical aspects of childhood cancer.
