CiNA Explorer - NAACCR Cancer Statistics

CiNA Explorer Help

CiNA Explorer is an interactive tool for quick access to a wide range of NAACCR cancer statistics organized by cancer site and by demographic characteristics such as sex, race/ethnicity, age, and calendar year. A select number of cancer sites may also be viewed by stage at diagnosis. Statistics may be viewed as graphs or tables and downloaded for use in other programs.

The CiNA Explorer allows for direct comparison of one characteristic at a time (such as Race/Ethnicity or Sex) for selected groups. For example, you can compare Recent Trends of Lung Cancer Incidence by Race/Ethnicity for Women.

Using CiNA Explorer

Quick Start Guide

The following steps provide an overview on how to use the CiNA Explorer application.

  1. Select a registry using the Get the Started with a Registry dropdown list.
    • Select from the list or in the first field of the list begin typing a registry to see the available options that match your term.
    • Note: Stage Distribution and Race/Ethnicity data are only available for US Registries.
  2. Select a cancer site using the Choose a Cancer Site dropdown list.
    • Select from the list or in the first field of the list begin typing a cancer site name to see the available sites that match your term.
    • Note: Only breast, cervical, colorectal, lung & bronchus, and prostate cancer have Stage Distribution data presented.
  3. Select a graph type from those available by clicking on the tab.
    • Some graphs are line graphs while others are bar graphs depending on which is more appropriate to your selection.
    • You can move from the Graph tab to the Data Table tab to see specific numbers.
    • The graph and data table will automatically update as you make selections.
  4. Select a Compare By variable tab.
    • The variable tab opens with the primary variable (the Compare By variable) at the top.
    • You can select Sex, Race/Ethnicity (U.S. Only), Age, or Registry to compare by.
    • Multiple variable values can be selected for the primary variable. For example, when comparing by gender you can select one or more of the choices which are Both Sexes (combined), Female, and Male.
  5. Age, Sex, Race/Ethnicity (U.S. Only), Stage at Diagnosis (U.S. Only)
    • The variables not selected as the variable to Compare By are secondary variables.
    • Select values for the secondary variables by clicking on the plus sign to open the dropdown lists and selecting a radio button next to value you want to use.
    • The secondary variables can only have one value at a time.
  6. Select a Graph or a Data Table by clicking on the tab.
    • Some graphs are line graphs while others are bar graphs--depending on which is more appropriate for your selection.
    • You can move from the Graph tab to the Data Table tab to see specific numbers.

  • Precision – The number of decimal places shown in the table for Annual Percent Change (APC) or Rates may be specified here. You can set the value to 0.1, 0.01, 0.001, or 0.0001.
  • Show Confidence Interval – When this option is checked, the confidence intervals (CI) will be displayed in the data tables as columns for C.I. Low and C.I. High. The values will also be displayed if you hover over a data point on the graph.
  • Show Counts – When this option is checked, the average annual count will be displayed in the data tables as columns. The values will also be displayed if you hover a data point on the graph.

Available Statistics

CiNA Incidence

CiNA Incidence is the number of new cases of the specific cancer site/type per 100,000 people. Number of new cases per number of people in a population are also referred to as incidence rates.


Relative survival is an estimate of the percentage of patients who would be expected to survive the effects of their cancer. It excludes the risk of dying from other causes. Relative Survival statistics compare the survival of patients diagnosed with cancer with the survival of people in the general population who are the same age, race, and sex and who have not been diagnosed with cancer.


Cancer Prevalence is the number or percent of people alive on a certain date who have been diagnosed with cancer. In Prevalence we show limited-duration prevalence which represents the proportion of people alive on a certain day who had a diagnosis in the 2, 5, or 10 years prior to the prevalence date. Limited duration prevalence is presented as U.S. counts or percent of the U.S. population by age, sex, race and time since diagnosis.

Standard Populations

Rates are per 100,000 population and are age-adjusted by five-year age groups to the 2000 U.S. standard population based on single years of age (Ries, et al. 2005) and the 2011 Canadian standard population.

  • Age-Adjusted Rate
    A method allowing comparisons of populations that takes into account age-distribution differences between populations.
  • Annual Percent Change
    Used to measure trends or the change in rates over time.
  • APC/Rate Precision
    The number of decimal places shown in the data table.
  • Cancer Sites
    Refer to the CiNA Explorer Cancer Site Definitions for more information
  • Confidence Interval
    A range of values that have a specified probability of containing the rate or trend.
  • P-Value
    Used in the calculation of confidence intervals and in significance testing. The default value for all p-values is 0.05 (equivalent to a 95% confidence interval or 0.05 significance).
  • Stage at Diagnosis
    The stage that the cancer has progressed to at the time of diagnosis.
    • In Situ: Requires Microscopic Review, Non-invasive
    • Localized: Confined to the Primary Site
    • Regional: Spread to Regional Lymph Nodes
    • Distant: Cancer Has Metastasized
    • Unstaged: Unknown (or Not Enough Information to Indicate a Stage)
  • Standard Error
    The standard error of an estimate is a measure of the sampling variability of the estimate.

Frequently Asked Questions

  1. How do I do cross-comparisons of multiple characteristics, for example Race and Sex?
    In CiNA Explorer, you can only compare one characteristic at a time (chosen on the Compare By box). To do cross comparisons for example, lung cancer incidence rates by Race and Sex, you can download the data in CSV format to be used with external graphic software like Microsoft Excel.
  2. How do I compare multiple registries?
    In the current version of CiNA Explorer, you can compare registries by:
    • Choosing one registry from the Get Started with a Registry dropdown at the top
    • In the Compare By section, choose the option NAACCR Registry
    • Click or tap the Select Registries button to get a list of all registries
    • Choose your registries and select Compare in the window when done
  3. Where do I go for Technical Support?
