In cancer epidemiology, prospective approaches are very important both in testing etiological hypotheses and in evaluating preventive procedures. Prospective studies, however, are very difficult and expensive, because a large number of people and a long period of observation are necessary for a satisfactory study. As a data source for follow-up studies, population-based cancer registry is very ...

Introduction Progress in cancer prevention and treatment depends on the collection and analysis of reliable information about the incidence, risk factors, and progression of cancer in the Canadian population. Every jurisdiction in Canada has a public cancer registry, operated by a cancer agency or subsumed within another government department or ministry. These registries contain comprehensive ...

The early cancer studies on immigrants, which started to appear some 50 years ago, showed that the incidence in cancers changes to the level of the new host country in one or two generations. These findings were fundamental to the understanding of the environmental etiology of human cancer. Many immigrant groups originate from countries with no cancer registration, and, hence, the immigrant stu...

Background and Objective Genderand age-specific differences in melanoma incidence are poorly defined in the literature. The purpose of this study was to evaluate such gender-and age-related differences in melanoma incidence rates using large population-based U.S. datasets. Methods Data for this study were obtained from three cancer registries: the Cancer Surveillance Program of Orange County/Sa...

PURPOSE Global cancer burden has increasingly shifted to low- and middle-income countries and is particularly pronounced in Africa. There remains a lack of comprehensive cancer information as a result of limited cancer registry development. In Moshi, Tanzania, a regional cancer registry exists at Kilimanjaro Christian Medical Center. Data quality is unknown. Our objective was to evaluate the co...

Standardized management of data elements (DEs) for Case Report Form (CRF) is crucial in Clinical Trials Information System (CTIS). Traditional CTISs utilize organization-specific definitions and storage methods for Des and CRFs. We developed metadata-based DE management system for clinical trials, Clinical and Histopathological Metadata Registry (CHMR), using international standard for metadata...

Timely monitoring of trends in long-term patient survival is an important task of cancer registries. Recently, a new method, denoted period analysis, has been proposed to enhance up-to-date monitoring of survival. The authors assessed the use of period analysis for advanced detection of time trends in long-term cancer patient survival based on data from the nationwide Finnish Cancer Registry by...
