Incidence and mortality of colorectal cancer in Zhejiang Province / 预防医学

Objective@#To understand the incidence and mortality of colorectal cancer in tumor registration areas of Zhejiang Province,and to provide reference for prevention and control strategies for colorectal cancer.@*Methods@#The colorectal cancer data was retrieved from fourteen tumor registries in Zhejiang Province were collected,the incidence rate and mortality rate were calculated and standardized according to the Chinese standard population in 2010 and Segi's world population in 2000. The incidence and mortality of colorectal cancer in different sex,age group and region were analyzed.@*Results@#The crude incidence rate of colorectal cancer from 2010 to 2014 was 35.82/100 000（20 983 cases）. The standardized incidence rate by Chinese and world standard population were 20.80/100 000 and 23.01/100 000. The crude mortality rate of colorectal cancer was 15.25/100 000 （8 934 cases）. The standardized mortality rate by Chinese and world standard population were 8.01/100 000 and 9.39/100 000. The ratio of mortality to incidence was 0.43:1. From 2010 to 2014,the incidence and mortality rates of colorectal cancer were stable（P>0.05）. The incidence rates of colorectal cancer in urban and rural residents were 37.69/100 000 and 31.14/100 000,and the mortality rates were 15.73/100 000 and 14.05/100 000. The incidence rates of colorectal cancer in males and females were 41.53/100 000 and 30.11/100 000,and the mortality rates were 17.74/100 000 and 12.76/100 000. The incidence and mortality rates of colorectal cancer both increased with age. The incidence rate increased significantly in people after 40 years old,and peaked with 187.35/100 000 in people aged 80-84 years. The morbidity rate peaked with 171.27/100 000 in people aged 85 years or over. @*Conclusion@#The incidence and mortality of colorectal cancer in Zhejiang Province were stable,but the incidence was higher than the national average level. The incidence of colorectal cancer in people aged over 40 years increased significantly.

Melanoma cutáneo: mortalidad y características de los tumores incidentes en los dos extremos de la vida en la Argentina / Cutaneous melanoma in argentina: mortality and primary tumor

Objetivos. Conocer y comparar en la Argentina, en los jóvenes y adultos, la mortalidad por melanoma cutáneo (MC) y las características de casos incidentes para aportar información útil en el diseño y evaluación de acciones de prevención. Diseño. descriptivo y retrospectivo. Métodos. Se consideraron para el estudio: los jóvenes < 30 años (J) y adultos > 74 años (AM). Los datos de las defunciones para el cálculo de tasas de mortalidad en los períodos 1981-89, 90-98 y 99-07 fueron proporcionados por la Dirección de Estadísticas e Información de Salud del Ministerio de Salud. La información sobre los casos incidentes se obtuvieron del Registro Argentino de Melanoma Cutáneo (RAMC) para el período enero 2002- diciembre 2009. De ellos se estudió la localización, el espesor de Breslow y el tipo histológico.Resultados. En los sucesivos períodos las muertes por MC en J de ambos sexos fue 97, 93 y 123, y en AM 416, 654 y 1.307, respectivamente. En los AM las tasas de mortalidad aumentaron en el tiempo, y fueron siempre menores para las mujeres que para losvarones (varones: 6,3 muertes por MC promedio por cada 100.000 individuos por año en 81-89 a 13,4/100.000 99-07; mujeres: 4,4/100.000 81-89 a 7,5/100.000 en 99-07). El RAMC registró 4.100 casos, 258 fueron en J y 665 en AM. Fueron mujeres el 63% en J y el 47% en AM (p< 0,05). En las mujeres, el 56% de los MC en J y el 36% en AM tuvieron Breslow ≤ 1,00 mm (p< 0,004). En las mujeres predominaron las lesiones en piernas (el 43,4% en J y el 42,2% en AM), mientras que en los hombres fueron el 19,8% y el 12,4% respectivamente (p< 0,005). Conclusión. En las mujeres jóvenes, el menor espesor de Breslow al momento del diagnóstico y las menores tasas de mortalidad por MC con menor incremento temporal de las mismas podrían ser reflejo de una mayor influencia de las acciones de prevención y una mayor atención del propio cuerpo y de la salud por parte del género femenino. Cabe esperar que la continuidad de las actividades del ...

Objectives. To compare mortality rates and main features of cutaneous malignant melanoma(CMM) between two age groups in Argentina (young and elderly patients), in order to increaseknowledge as well as improve planning and preventive actions for this disease.Study design. descriptive and retrospective.Methods. Group J was defined as patients younger than 30 years of age and Group AM patientsover 74 years old. Death reports for periods 1981-89 / 90-98 / 99-07 were provided by theDepartment of Statistics of the Health Ministry and incident cases between 2002 and December2009 by the Argentine Registry of Cutaneous Malignant Melanoma (RAMC). Tumor location,Breslow thickness index and histopathology characteristics were analyzed for all cases.Results. For successive periods, the total number of CMM-associated deaths for both gendersin Group J was 97, 93 and 123 respectively; while these figures were for Group AM 416, 654 and1,307 respectively. On older patients an increase in mortality rates was observed over elapsedtime, being always lower for women than for men (mortality rates for men were 6.3 /100,000population per year during the period of 1981-1989 and 13.4/100,000 between the years1999-2007. Mortality rates for women were: 4.4/100,000 during 1981-1989 and 7.5/100,000and in 1999-2007). RAMC registered 4,100 new cases, of which 258 belonged to Group J and665 to Group AM. Women comprised 63% on group J and 47% on group AM (p<0, 05). Womencomprised 56% of CMM in Group J and 36% on Group AM, having a Breslow tumor thickness≤ 1.00mm (p<0,004). Primary tumors located on lower limbs were more frequently observedamong women (43.4% and 42.2% for Group J and AM respectively), whereas on men this was19.8% and 12.4%, respectively (p<0,005)...

Análisis de un registro de adenomas pituitarios / Analysis of a pituitary adenoma registry

Dada la complejidad que reviste el enfoque diagnóstico y terapéutico de los tumores pituitarios, el registro y análisis de la experiencia clínica acumulada es de gran ayuda en la toma de decisiones. En este trabajo se informan datos clínico-terapéuticos, extraídos de un registro computarizado, sobre 519 de un total de 670 pacientes con adenomas pituitarios. Trescientos cuarenta y cinco fueron mujeres (66%) y 174 varones (34%), de 14 a 80 años de edad. El diagnóstico final fue: acromegalia en 176, enfermedad de Cushing en 153, prolactinoma en 101 y adenoma clínicamente no-funcionante (ANF) en 89. La edad media al momento del diagnóstico de acromegalia fue 43.9 ± 13.5 (16-80), para enfermedad de Cushing 35.7 ± 12.9 (14-72), para prolactinomas 30.0 ± 13.4 (15-79) y para ANF 52.1 ± 15.2 (17-79) años. La creación de un registro institucional de tumores de hipófisis es un instrumento de gran utilidad para el análisis de la experiencia adquirida y constituye una herramienta valiosa para mejorar la estrategia terapéutica, optimizar la relación costo/beneficio y mejorar el cuidado del paciente. Contribuye a la docencia médica, tanto en el pre como en el posgrado y da base a la realización de trabajos de investigación clínica, aportando a la difusión y transferencia de conocimientos.

Collection and analysis of data obtained during the clinical treatment of pituitary tumours are of great utility in the decision making process, when facing clinical situations. We report here data on 519 from 670 patients with pituitary adenomas obtained from a computerized registry. Three hundred and forty five were females (66%) and 174 males (34%), aged 14-80. Final diagnosis was acromegaly in 176, Cushing's disease in 153, prolactinoma in 101 and clinically non-functioning adenoma in 89. Mean age at diagnosis was 43.9 ± 13.5 (16-80) for acromegalics, 35.7 ± 12.9 (14-72) for Cushing's, 30.0 ± 13.4 (15-79) for prolactinoma and 52.1 ± 15.2 (17-79), for non-functioning tumours. The setup of an institutional registry on pituitary tumours constitutes a useful tool to analyze clinical experience, optimize the cost/benefit ratio of procedures used for diagnosis and to ameliorate therapeutic strategies, improving patient's care. It greatly contributes to teaching medical students as well as to post-graduate physicians and provides a basis for developing clinical research.

Evaluation of Tumor Registry Validity in Samsung Medical Center Radiation Oncology Department / 대한방사선종양학회지

PURPOSE: A tumor registry system for the patients treated by radiotherapy at Samsung Medical Center since the opening of a hospital at 1994 was employed. In this study, the tumor registry system was introduced and the validity of the tumor registration was analyzed. MATERIALS AND METHODS: The tumor registry system was composed of three parts: patient demographic, diagnostic, and treatment information. All data were input in a screen using a mouse only. Among the 10,000 registered cases in the tumor registry system until Aug, 2002, 199 were randomly selected and their registration data were compared with the patients' medical records. RESULTS: Total input errors were detected in 15 cases (7.5%). There were 8 error items in the part relating to diagnostic information: tumor site 3, pathology 2, AJCC staging 2 and performance status 1. In the part relating to treatment information there were 9 mistaken items: combination treatment 4, the date of initial treatment 3 and radiation completeness 2. According to the assignment doctor, the error ratio was consequently variable. The doctors who did no double-checks showed higher errors than those that did (15.6% : 3.7%). CONCLUSIONS: Our tumor registry had errors within 2% for each item. Although the overall data quality was high, further improvement might be achieved through promoting sincerity, continuing training, periodic validity tests and keeping double-checks. Also, some items associated with the hospital information system will be input automatically in the next step.

A Consideration to Brain Tumor Registry in Korea

The information obtained from epidemiology of brain tumor provide the key to the natural history of brain tumors and could be used for many different things, among others, the planning of hospitals and hospital care facilities and working out the medical requirements for each region. To cope with changing needs in this field due to the application of medical insurance to all Korean citizens from July 1. 1989, the brain tumor registries of various countries were reviewed and suggestions were made about Korean Brain Tumor Registry that should be prepared in the near future.
