Meeting Information

3/4/15 | Journal Club: Using the National Death Index to Identify Duplicate Cancer Incident Cases in Florida and New York; 1995 – 2004

The NAACCR Journal Club discussed the article “Using the National Death Index to Identify Duplicate Cancer Incident Cases in Florida and New York; 1995 - 2004". The discussion was led by Brad Wohler from the Florida Cancer Data System and Baozhen Qiao from the New York State Cancer Registry.

Reda Wilson, from the CDC Cancer Surveillance Branch, discussed the National Death Index agreement and how staff from cancer registries can share information from NDI linkage to identify potential duplicate incidence cases.

1/29/15 | Cancer Surveillance Webinar Series - Dynamically Generating Statistical Cancer Reports Efficiently: Getting the best bang for your buck

Presenter: Kim Herget

Monitoring regional cancer rates is critical for strategic local and state planning and can provide a “report card” on the health of a community and insight into how well cancer prevention programs are working. However, with increasingly scarce monetary resources, producing local cancer reports on a regular basis can be challenging. We tried to develop best practices for creating effective and easily updateable cancer reports in a timely manner using limited resources. NAACCR and NCI both have an abundant array of freely available software tools for analyzing cancer statistics. Utilizing these tools in conjunction with integrated Microsoft Office products resulted in quicker updates for our Cancer in Utah reports. Ultimately, the key to refining and streamlining the process was planning. Once specific table and figure formats were developed, updating them from year to year became much quicker and less resource intensive.

12/3/14 | Delay Adjustment for NAACCR Registries

The link to a live recording is available at https://naaccrinc.webex.com/naaccrinc

Presenter: Eric J. (Rocky) Feuerer

The most recent diagnosis year included in a December submission to NAACCR is two years prior to the submission (e.g. the December 2014 submission includes cases diagnosed through 2012). Subsequent submissions include cases that had previously been unreported (delayed) and are added, while corrections may cause cases be removed or added to one category and removed from another. Because more cases are added than removed during this process, the observed rates from recent submissions are too small. Underreporting in the most recent years is largest, and this biases the trends downward. The most recent data points are considered the most important because any small change is seen as a potential harbinger of the impact of cancer control activities. To adjust for this, a statistical model has been developed to estimate “reporting delay-adjusted” rates, which represent projections to more closely approximate actual rates. Delay-adjusted rates have previously been developed for the SEER 9 and SEER 13 registries. This webinar will describe the process to develop delay adjustment factors for all registries in NAACCR that have a sufficient history of submissions in which the data are deemed “fit for use”. Delay adjustment factors will be developed based on the December 2014 NAACCR submission, and then shared for common use with NCI (the SEER Program), CDC (the NPCR program), and NAACCR. SEER*Stat has been modified to allow for the computation of delay adjusted rates and their standard errors for any set of registries. While each registry will have their own set of delay adjustment factors, in this first release delay-adjusted rates will only be reported for large aggregations of registries (e.g. SEER9, SEER 13, US, Canada, regions of the US). Individual registries will get a report with their own delay adjusted rates, and will have an opportunity to provide feedback to the modeling team prior to the development of delay factors based on the December 2015 submission.

  • Delay Modeling Across NAACCR Registries
  • 10/1/14 | Surveillance Webinars Session 2 - Prevalance

    The link to a live recording is available at https://naaccrinc.webex.com/naaccrinc

    Cancer prevalence data are increasingly in demand for use across the cancer control continuum. For the next installment of the NAACCR Surveillance Webinar Series, Dr. Angela Mariotto of the National Cancer Institute and Mr. Steve Scoppa of Information Management Services Inc. will provide an overview of methodologies and tools that are available to estimate the prevalence of cancer.

    The session began with a discussion of the strengths and limitations of survey and registry-based data for calculating prevalence. We then contrasted “complete” and “limited-duration” prevalence estimates. The presentation also included a demonstration of SEER*Stat. 

  • An Overview of Prevalence Statistics from SEER
  • 9/25/14 | Registry of the Future Town Hall

    The link to a recording of the live session is available at: https://naaccrinc.webex.com/naaccrinc | This webinar was brought to you by the Registry Operations Advisory Group of NAACCR. Some of the issues that were discussed include:

  • The registry of the future will have to include concurrent abstracting
  • It will have to be paperless
  • Availability of data sources will have to be uniform, or otherwise, registries could specialize and collaborate
  • Review of guidelines around data ownership, use of big data, linkages across data sets
  • Consider linkage to tissue repositories
  • More data is needed in discrete format
  • Multiple, interoperable formats for gathering specific segments of the data set
  • More granular, "mini" data sets enabled by interoperability and flexible formats
  • Longitudinal patient follow-up enabled by complete, accessible health records
  • The registry "client base"; should always include Surveillance but could also include others – physicians, researchers, patients, tissue banks, other disease registries
  • The registry of the future could be built like a disease registry
  • It could support the patient journey
  • It could be interactive with patient and doctor
  • It could more directly influence health care
  • It should always maintain its core values

    An Introduction to Collaborative Stage Version 02.04 for Software Developers and IT Staff

    The Collaborative Stage Workgroup presented a webinar on Thursday, November 17 for CS vendors, software developers, and registry managers. The focus of the webinar was on the upcoming release of CS version 02.04, and highlighted the changes incorporated into this new release.

    10/27/11 | Shortest Path Tool

    Using this tool, NAACCR members can easily compute shortest travel time or distance between two locations, for instance, residence at diagnosis and treatment center. The resultant data enable researchers to evaluate the impact of travel time or distance on cancer outcomes, such as stage at diagnosis, treatment received, or survival.

    During this audio/video enabled WebEx conference, members of the NAACCR GIS Committee will present how the system works to the broader NAACCR community. Presenters at this meeting will include Recinda Sherman – GIS Committee Chair (Florida Cancer Data Systems); Frank Boscoe, Kevin Henry, and Chris Johnson – the authors of two research papers already published using the Shortest Path Tool (New York Cancer Registry, University of Utah, and Cancer Data Registry of Idaho, respectively); and, Daniel Goldberg – developer of the shortest path tool (University of Southern California Spatial Sciences Institute and Los Angeles County Cancer Surveillance Program). Recinda will provide an overall context for the tool, Chris, Frank and Kevin will describe how the tool can be used in research studies, and Dan will provide a hands-on demonstration of how the tool operates. The Town Hall is appropriate for all members of the NAACCR community and particularly for researchers, analysts, and managers interested in studies addressing the influence of distance on cancer diagnosis, progression, and survival.

    6/9/11 | Hospital Discharge Data

    The NAACCR Discharge Data Work Group, the National Program of Cancer Registries-Advancing E-cancer Reporting and Registry Operations (NPCR-AERRO) and the National Association of Health Data Organizations (NAHDO) have been working together on a hospital discharge data project. Hospital discharge data, all-payer claims data and cancer registry data have typically been used as separate resources for understanding cancer prevalence, incidence, resource use, quality of care and cost. There are opportunities to link these sources to further address important questions for cancer researchers, epidemiologists, health services researchers, policy makers, and program managers.

    The purpose of this project was two-fold. First, a gap analysis was conducted to address data elements that could be standardized, added or improved between these data types. Second, an examination of the types of questions that could be answered, using combined databases, was developed. Recommendations on the GAP analysis are found in the NAACCR-UB-GAP document (this document will be provided prior to the town hall meeting); this document addresses a prioritized list of questions. In addition, for those questions given high priority, we provide the key data elements necessary to answer the question. This paper was produced by NAHDO. State agency, federal staff, and work group members provided NAHDO with input on the gaps, priorities, and limitations of the data sources.

    The NAACCR Town Hall gave NAHDO staff the opportunity to present their documents to the NAACCR membership. The meeting fostered an exchange of ideas and allowed members to ask questions of the NAHDO experts.
