What Is a Cancer Registry?

• Information system designed to:

– Collect

– Manage

– Analyze

data on persons with the diagnosis of a malignant or neoplastic disease (cancer).

• Cancer registries can be classified into three general types:

– Hospital based registries: maintain data on all patients diagnosed

and/or treated for cancer at their facility and report cancer cases to the central or state cancer registry as required by law.

– Population-based central registries: maintain data on all cancer patients within certain geographical areas.

– Special purpose registries: maintain data on a particular type of cancer, such as brain tumors.

What Is a Cancer Registry?

• Registry data is:

– Used to make public health decisions – A valuable research tool for those interested

in the etiology, diagnosis and treatment of cancer

– Used in fundamental research on the epidemiology of cancer

Page 5: Cancer Registries and Medical Records Rich Data Resources

What Is a Cancer Registry?• Information maintained in a cancer registry:

– Demographic Information: Age, gender, race/ethnicity, birthplace and residence.

– Medical History: Physical findings, screening information, occupation and any history of a previous cancer.

– Diagnostic Findings: Types, dates and results of procedures used to diagnose cancer.

– Cancer information: Primary site, cell type and extent of disease.

– Cancer Therapy: Surgery, radiation therapy, chemotherapy, hormone or immunotherapy.

– Follow-up: Annual information concerning treatment, recurrence, and patient status is updated to maintain accurate surveillance information.

What Is a Cancer Registry?

How are these data used? • Evaluate patient outcome, quality of life, and satisfaction issues and

implement procedures for improvement • Provide follow-up information for cancer surveillance • Calculate survival rates by various data items • Provide information for cancer program activities • Analyze referral patterns • Allocate resources at the health care facility, the community, region

or state level • Develop educational programs for health care providers, patients

and the general public • Report cancer incidence as required under state law • Evaluate efficacy of treatment modalities

History of Cancer RegistriesCancer Registration

• Late 16th Century

Prompted by the seemingly random geographic ravages of the plague, the English Crown appointed elderly, epidemic-scarred women to prowl the countryside in search of the dead and dying. These 'Ancient Matrons' published weekly 'Bills of Mortality' for each parish, tabulating deaths by causes such as 'the purples' (probably leukemia), 'riting of the lights', 'consumption' (often an effect of cancer), and of course, the plague. Just how this information was used is not recorded. Perhaps the royalty found it helpful to determine where the plague was active so they could be somewhere else

History of Cancer RegistriesCancer Registration

• Mid 17th Century

Around 1665 a London businessman, John Graunt, created medical history by subjecting decades of mortality data to critical and mathematical analysis. He literally invented the science of medical epidemiology and statistics, publishing a pamphlet with 108 conclusions. The list included such revolutionary observations as the facts that women saw physicians twice as often as men yet lived longer, and plague epidemics moved outward from swampy areas. Graunt also was the first person to use mortality statistics to project population survival, probably by crudely fitting data samples to a logarithmic curve.

Rapid Case Ascertainment

• Provides the ability to identify cancer cases shortly after diagnosis

• Central registry editing and consolidation can be time consuming

• Located within central cancer registries and/or at academic medical centers

Page 72: Cancer Registries and Medical Records Rich Data Resources

Rapid Case Ascertainment

Value to researchers: provides immediate access to patients

• Interview patients prior to surgery• Obtain blood/DNA etc.• Initiate a series of questionnaires over time (i.e. 3, 6 and

9 months after diagnosis)• Interview patients about lifestyle elements that might tend

to change after diagnosis (alcohol consumption, smoking history)

Page 73: Cancer Registries and Medical Records Rich Data Resources

SEER Rapid Response Surveillance Studies

• Began as Patterns of Care Studies

• Evolved into a mechanism that allows studies to move from the initial concept through completion in a relatively short interval, usually within two years

• Studies address new and emerging issues related to cancer prevention and control

• Conducted through he SEER Registries

• Largely pathology based active case-finding (e-path or circuit riding) vs. waiting for reports to be sent to the central registry

Page 74: Cancer Registries and Medical Records Rich Data Resources

Limitations of Using Cancer Registry Data

• Limited data set – extensive, but limited• Strict rules for data collection – good, but

restrictive• Time delays – data can be 1 to 2 years old• Data collected and defined by the priorities of

others• Dataset designed by committee

Page 75: Cancer Registries and Medical Records Rich Data Resources

Limitations of Using Cancer Registry Data

• Reliance on primarily pathology based case-finding – image and lab based dx’s may not be as readily picked up (pancreas, brain, multiple myeloma)

• Majority of cases reported by hospitals – some lab and outpatient reporting

• Data can be limited by information captured only through the hospital system

• Outpatient information is often missing – XRT at freestanding centers, CTX in MD offices

Page 76: Cancer Registries and Medical Records Rich Data Resources

Limitations of Using Cancer Registry Data

• Lack of information about events leading up to dx – screenings, health behaviors

• Limited information about co-morbid conditions

• Follow-up information often limited to vital status – no detailed information on side effects to tx, tx compliance

• Very little information about recurrence of disease

Page 77: Cancer Registries and Medical Records Rich Data Resources

Medical Record Review

• Advantages– Flexibility– Timeliness– Customized data set– Investigator control

Page 78: Cancer Registries and Medical Records Rich Data Resources

Medical Record Review – Recent Examples

• Helping Ourselves Helping Others

PI: Ann Partridge, MD

Breast cancer in women 40 and under

Captured within 16 weeks of dx

Cases identified and reviewed at DFCI, MGH, BWH, NWH, Faulkner, BIDMC, North Shore Cancer Center, Lowell General

Page 79: Cancer Registries and Medical Records Rich Data Resources

Medical Record Review – Recent Examples

• The Environment, Genes and Testicular Cancer

PI: Russ Hauser, MD

Newly diagnosed cases of testicular cancer

Identified shortly after dx at DFCI, MGH, BWH, Faulkner, North Shore, BIDMC, Boston Medical Center, Lowell General, Tufts-NEMC

Page 80: Cancer Registries and Medical Records Rich Data Resources

Medical Record Review – Process

• Plan data set with investigator/study team– Define data elements and data definitions

(coded 1, 2 responses vs. yes, no)– Think about the future

• Will this data be linked or compared to other data sets – should race and ethnicity be collected using cancer registry/census rules

• What is being measured – can’t evaluate data that hasn’t been collected

Page 81: Cancer Registries and Medical Records Rich Data Resources

Medical Record Review – Process

• Design/program the data collection tool– Access, Excel, other programs– Consider output – where is the data going-

other databases, are the variables the same

Medical Record Review – Process

• Define rules for:– Missing data– Incomplete data– Illegible data

• Keep in mind– Medical records are not designed for

research, there are limits to what they contain

Medical Record Review – Process

• Develop case identification procedures– Review eligibility criteria– Identify facilities– Case sources

• Pathology• Radiology• New patient admission/visits• Clinic logs

– Access to case sources• Who has access• How does one obtain access• Is training required

Medical Record Review – Process

• Consider the frequency of data collection– Is time to dx important– Are there other patient or patient flow events to

consider• How often do patients come in for treatment• Do they stay in the hospital• Is there a planned schedule of testing

– Many cases will need to be reviewed to find eligible cases – this can be time consuming

Medical Record Review – Process

• Work with investigator/study team on IRB issues– Provide background information on personnel– Provide information about methods for identifying

cases

• Build in quality control measures– Computerized edits– Double abstraction (5-10%, inter rater reliability > 95%)
