The REPCAN Guideline Checklist Final Draft

Manuscript Section		Item No	Item Description
Title and abstract
Title		T1	- Indicate the name of the cancer registry, the type of registry, the time period to which the report relates, and the relevant country/region.
			- If a part of the results is reported, such as child/adult cancer or selected sites, this information should be included in the Title.
Abstract	Objective	A1	Present the objective of the report, the registry name(s), the time period to which the report relates, and the population name (e.g., country/country region/ethnic group, etc.)
	Methods	A2	Briefly indicate: whether the data are population-based, institutionally based, or otherwise/time period/the process whereby registration takes place/the major data source(s)/the population source and its ethnic characteristics and other features
	Result	A3	Report the crude and age-standardized rates for all cancers combined and major cancers recorded by the registry, plus at least one index of data quality
	Conclusion	A4	Provide a conclusion on reported results including a qualitative assessment of the report
Introduction
	Background /Rationale	I1	Consider adding the context of broader cancer control planning in the country/region and specific cancer prevention activities.
		I2	Include references describing the population denominator, the cancer registry, the relevant history of cancer registration, and the data gap filled by the report
		I3	The report, numbers, proportions, incidence, and mortality rates of cancers based on available reporting for the study population or comparable populations
	Objectives	I4	State-specific objectives of the Cancer Registry
Methods
Study design		M1	- Present key elements of registry design (e.g., type of registry, organization).
			- State how the registry is managed. Is the registry part of a standalone project (give identifiable information), or part of an ongoing registry?
		M2	Indicate the name of the registry and the “target” population to which it refers
Study population and registration area		M3	Indicate population characteristics (e.g., ethnic subgroups) of the registration area and present population pyramid
		M4	Describe geographic and environmental characteristics (e.g., climate, altitude, latitude) of the registration area
Data collection and definitions		M5	Provide sources of population and mortality data
		M6	Describe the reporting procedures (e.g., active or passive reporting) used by the registry
		M7	Indicate data sources (e.g., hospitals, diagnostic laboratories, and death certificates) including those in the private or public sectors
		M8	Include descriptive variables relating to the person with cancer (sex, age, ethnic group), place of residence, and time
		M9	Include descriptive variables relating to cancer (e.g., diagnosis date, the valid basis of diagnosis, topography, morphology, behavior, grade, stage)
		M10	Describe the standard cancer classifications and coding systems used by the registry including ICD-O or other classification versions used
Quality control		M11	Describe methods used to ensure data validity (e.g. comparability, accuracy, and completeness)
		M12	Provide descriptions of indices used to indicate data quality (e.g. comparability, accuracy, and completeness)
Statistical analysis		M14	Name the statistical software used
		M15	Describe the statistical terms and methods
		M16	Describe the calculated statistics and finding reported (e.g. number of cases, age-specific rates, crude rates, and age-standardized rates)
		M17	Describe methods used for the calculation of standardized rates and indicate the standard population with appropriate reference
Ethics code		M18	Describe ethical considerations about registry-based research in your country/region and report the approval awarded by an ethics committee
Results
Frequencies		R1	Provide a table showing available demographic data (e.g., sex, age groups, place of residence, ethnicity)
		R2	Report frequency distributions of cancers by site, age, sex, and period/year (Preferred groupings would align with Cancer in Five Continent or ICD-OC groupings)
		R3	Make appropriate use of tables, bar graphs, pie charts, and line graphs for the presentation of frequencies
Manuscript Section				Item No	Item Description
Results
Rates				R4	Report crude annual incidence rates by site, age, and sex
				R5	Report age-standardized rates by site, age, and sex (preferably using a relevant WHO standard population)
				R6	Report cumulative incidence rates by site, age, and sex
				R7	Show a graphical representation of age-specific incidence rates by sex, for commonly diagnosed cancers
				R8	Make appropriate use of tables, bar graphs, pie charts, and line graphs for the presentation of rates
Geographical distributions				R9	Report frequencies and rates by geographic subdivisions of the registration area
Indices of data quality				R10	Include a table of indices of the validity of diagnoses
				R11	Report the percentages of cases with a morphologically verified diagnosis (MV%) and where the data source was a death certificate only (DCO%) (note: where available)
				R12	Report other indices of data quality (e.g., mortality/incidence ratio (note: where available)
Discussion
Key results				D1	Summarize key results as relating to study objectives
Interpretation of results				D2	Compare observed incidence and mortality results with corresponding results for other areas and populations
Data limitations				D3	Discuss the likely generalizability (external validity) of study results
				D4	Report the shortcomings of the registry and possible implications they may have for the accuracy and completeness of results
Acknowledgment section
