ABSTRACT
Esta pesquisa teve como objetivos analisar se os casos de câncer potencialmente relacionados ao amianto estão de acordo com o diagnóstico apresentado no Registro de Câncer de Base Populacional e verificar a sensibilidade e especificidade dos dados e relacionados às notificações e declarações de óbito. Trata-se de um estudo descritivo, retrospectivo e transversal, realizado em um registro de câncer de base populacional e em 11 fontes notificadoras, compreendendo hospitais, clínicas de anatomia patológica, unidade básica de saúde e no sistema de informação de mortalidade na cidade de Curitiba, Paraná. A amostra foi composta por 270 notificações de pacientes adultos com câncer de topografia C38 e C48. A coleta de dados foi referente às notificações de diagnóstico de câncer do período de janeiro de 1998 a dezembro de 2012. Para as análises estatísticas foi utilizado o software Stata 14®. Os resultados evidenciaram que, entre os cânceres estudados, 40,3% eram de peritônio e retroperitônio, 24,5% de mediastino e 11,5% de pleura e mesotelioma maligno. A média de idade dos pacientes com câncer de pleura e mesotelioma maligno foi de 66,3 anos, sete (70%) eram do sexo masculino, nove (90%) não possuíam registro sobre ocupação no prontuário e o tempo médio entre a data do diagnóstico e o óbito foi de 11,6 meses. Quanto à sensibilidade do registro com a notificação de câncer de pleura e mesotelioma maligno, esta foi de 100% e 50%, respectivamente. Em relação à especificidade, o registro apresentou 90% de concordância das notificações. Referente às notificações dos meios diagnósticos, os dados frequentes foram: histologia de tumor primário com 71,9% (n=194) e por declarações de óbito com 20,4% (n=55). Esses resultados expressam que não houve subnotificação para casos de mesotelioma maligno. Contudo, uma alta sobre a estimativa foi observada nas notificações de cânceres de pleura, decorrente da codificação equívoca da descrição da doença por parte do registro. Os resultados da pesquisa foram parcialmente de boa qualidade.

This research had as its objectives to analyze if the cancer cases are potentially related to asbestos according to the presented diagnosis by the registry of Cancer and Population Bases, and to verify the sensitivity and specificity of the data related to the notifications and statements of death. This is a descriptive, retrospective, and crosssectional study carried out in a population-based cancer registry and in 11 notifying sources such as hospitals, clinics of pathological anatomy, basic health units and in the mortality data system from the city of Curitiba located in the state of Paraná. The sample was composed by 270 notifications of adult patients with C38 and C48 topography cancer. The data collection had been done by searching for cases rated as cancer diagnosis reported from January 1998 to December 2012. Stata 14® software was used for the statistical analysis. The results clearly has shown that among the studied cases 40.3% were of peritoneum and retroperitoneum, 24.5% of mediastinum and 11, 5% of pleura and malignant mesothelioma. The average age of patients with pleural cancer and malignant mesothelioma was 66.3 years, seven (70%) were male, nine (90%) had no record of occupation on their medical records and the average time between the diagnostic and the death was 11.6 months. About the sensitivity from the registry with a notification of cancer of pleura and malignant mesothelioma, it was of 100% and 50% respectively. Regarding the specificity, the registry presented 90% an agreement of the notifications. Referring to the reports of the diagnostic ways, the frequent data has shown a histology of primary tumor with 71.9% (n = 194) and death declarations with 20.4% (n = 55). These results express that there was not underreporting for the cases of malignant mesothelioma. However, a high over estimate was noticed in reports of pleural cancers, as a result of the wrong coding of the disease description by the registry. The results of the survey were partially from good quality.

Introduction: Cancer is an important cause of morbidity and mortality worldwide. Population-based cancer registries (PBCRs) make possible to estimate the burden of this condition. Aim: To estimate cancer incidence and mortality rates in the Bucaramanga Metropolitan Area (BMA) during 2003-2007. Methods: Incident cases of invasive cancer diagnosed during 2003-2007 were identified from the Bucaramanga Metropolitan Area PBCR (BMA-PBCR). Population counts and mortality were obtained from the Colombian National Administrative Department of Statistics (NADS). We estimated total and cancer-specific crude incidence and mortality rates by age group and sex, as well as age-standardized (Segi's world population) incidence (ASIR(W)) and mortality (ASMR(W)) rates. Statistical analyses were conducted using CanReg4 and Stata/IC 10.1. Results: We identified 8,225 new cases of cancer excluding non-melanoma skin cancer (54.3% among women). Of all cases, 6,943 (84.4%) were verified by microscopy and 669 (8.1%) were detected only by death certificate. ASIR(W) for all invasive cancers was 162.8 per 100,000 women and 177.6 per 100,000 men. Breast, cervix, colorectal, stomach and thyroid were the most common types of cancer in women. In men, the corresponding malignancies were prostate, stomach, colorectal, lung and lymphoma. ASMR(W) was 84.5 per 100,000 person-years in women and 106.2 per 100,000 person-years in men. Breast and stomach cancer ranked first as causes of death in those groups, respectively. Conclusion: Overall, mortality rates in our region are higher than national estimates possibly due to limited effectiveness of secondary prevention strategies. Our work emphasizes the importance of maintaining high-quality, nationwide PBCRs.
Resumen. El cáncer es una causa significativa de morbi-mortalidad y conocer la magnitud del problema es posible gracias a los Registros poblacionales de cáncer (RPC). Objetivo. Describir las tasas de incidencia y mortalidad por cáncer en el área metropolitana de Bucaramanga (AMB) durante el quinquenio 2003-2007. Metodología. Los casos de cáncer invasivo primarios del período 2003-2007 se seleccionaron de la base del Registro poblacional de cáncer del área metropolitana de Bucaramanga (RPC-AMB). Los datos de población y mortalidad se obtuvieron del Departamento Administrativo Nacional de Estadística (DANE). Se estimaron tasas crudas de incidencia (TC) y mortalidad (TMC) totales y específicas por grupos de edad y sexo, y tasas de incidencia (TEE) y mortalidad (TMEE) estandarizadas. Los análisis estadísticos se hicieron con CanReg4 y Stata/IC 10.1. Resultados. Se reportaron 8.225 casos de cáncer incidentes al RPC-AMB durante el quinquenio (se excluye cáncer de piel no-melanoma), con un 54.4% de casos en mujeres. La TEE global fue de 177.6/100.000 hombres-año y 162.8/100.000 mujeres-año. Los cánceres más frecuentes para la población general fueron mama, próstata, estómago, colon y recto, y cuello uterino. La TMEE estimada en el AMB fue mayor que la cifra nacional, especialmente en los hombres. Conclusión.Las tasas globales de mortalidad por cáncer en nuestra región son más altas que el estimado nacional, lo que sugiere problemas en medidas de prevención secundaria. Las TEE de cáncer de mama y próstata aumentaron de acuerdo con las tendencias mundiales. Es necesario continuar los esfuerzos de vigilancia del cáncer.
ABSTRACT
It was not until 1975 that cancer registration was initiated in Korea; voluntary registration of cancer patients of training hospitals throughout the country began under the auspices of the Korean Cancer Society(KCS). However, an official cancer registration, the Korea Central Cancer Registry(KCCR), began on July 1st, 1980. Forty-five training and two non-training hospitals throughout the country initiated registration of patients in whom neoplasms had been found. Data related to case information specified are to be sent to the KCCR at the National Medical Center(it moved at National Cancer Center in 2000). The initial cancer registration of KCS was merged to the KCCR in 1980. Although the KCCR covers most all the large training hospitals in Korea, it cannot provide incidence data. It is, however, the only of its kind in the world, being neither hospital nor population based. The first population based cancer registry(PBCR) was launched in a small county, Kangwha(it has around 80,000 inhabitants), by Yonsei University Medical College in 1983. All data were collected by active methods, and incidence statistics for 1986-1992 appeared in Vol VII of the CI5. Another PBCR, Seoul Cancer Registry(SCR), started in 1991. It was supported by a civilian foundation, the Korean Foundation for Cancer Research. The basic idea of case registration of SCR was the incorporation of KCCR data to PBCR, e. g. dual sources of case registration, i.e., from the KCCR and also including cases diagnosed in small hospitals and other medical facilities. Assessing completeness and validity of case registration of SCR, the program and methodology used by the SCR was later extended to other large cities and areas in Korea, and the PBCR in each area was established. Cancer incidence statistics of Seoul for 1993- 1997, Busan for 1996-1997, and Daegu for 1997-1998, as well as Kangwha for 1993-1997, appeared eventually in Vol VIII of the CI5. The Korean or 'pillar' model for a PBCR is a new one. The KCCR data file is a reliable basis, as a pillar, for a PBCR in each area. The main framework of the model for such a registry is the incorporation of a KCCR data file with data from additionally surveyed cases; the data related to cancer deaths, medical insurance claims, and visit-and abstract surveillance of non-KCCR medical facilities. Cancer registration has been adopted as a national cancer control program by Korean government in 2004 as the Anti-Cancer Act was enacted. Since then, some officers have tried to launch a nation-wide PBCR covering whole country. In the meantime, however, cancer registration was interrupted and discontinued for years due to the Privacy Protection Law, which was solved by an amendment of the Anti-Cancer Act in 2006. It would be premature to establish the nation-wide PBCR in Korea. Instead, continuous efforts to improve the completeness of registration of the KCCR, to progress existing PBCRs, and to expand PBCRs over other areas are still to be devoted. The nation-wide PBCR in Korea will be established eventually with summation of the PBCRs of the Korean model.

PURPOSE: This study was carrid out to assess the feasibility of cancer registry program (KCR) in Kwangju metropolitan city, Korea. MATERIALS AND METHODS: The incidence cases and mortality data were mainly collected from the Korean national cancer registry system (NCR) and other resources such as medical insurance records, hospital records, pathology reports, radiation records and death certificates of 1996 in Kwangju metropolitan city. RESULTS: This study identified 1,422 cases of cancer in 1996, which was about 1379o more than NCR. Cancer cases reported from the hospitals outside Kwangju metropolitan city reached almost 40% of total cases. Death certificate notification percent (DCN%) in 1996 was estimated about 31.1%. The proposed KCR would cover more than 95% of cancer cases in Kwangju metropolitan city. CONCLUSION: The proposed KCR seems feasible in collecting cancer date with reasonable accuracy.
