New Jersey State Cancer Registry
Background






established by legislation – NJSA 26:2-104
et.seq.
a central cancer registry (i.e. populationbased incidence registry)
all cases of cancer diagnosed October 1978
to the present (about 40,000 a year)
except cervical cancer in situ diagnosed after
1994 and certain skin carcinomas
hospitals, clinical laboratories, physicians,
dentists must report cases
reporting agreements with New York,
Delaware, Pennsylvania, Florida, Maryland,
North Carolina
New Jersey State Cancer Registry
Background (cont.)





includes identifiers, demographic characteristics,
medical information, vital status for each case
cancer information is coded using the
International Classification of Disease for
Oncology (ICD-O), 2nd edition
follows data standards of the North American
Association of Central Cancer Registries
(NAACCR)
participates in CDC’s National Program of Cancer
Registries and NCI’s Surveillance, Epidemiology,
and End Results (SEER) program
an active member of NAACCR
New Jersey State Cancer Registry
Data Quality
recipient of NAACCR’s Gold Standard
(highest possible) for 1995 through 2000 data
 Gold Standard is based on:
– completeness of case ascertainment – >
95%
– missing/unknown age at diagnosis, gender,
county – each < 2%
– missing/unknown race - < 3%
– death certificate only cases - < 3%
– duplicate cases - < 1 per 1000
– passing an edit program – > 99% correct
– timeliness – data submitted within 24
months

New Jersey Cancer Incidence by County,
1996-2000 – Data Sources

data are from the May, 2003 analytic file
 tabulations using SEER*Stat, a statistical
software package distributed by NCI
 1996-1999 populations estimates from NCI
 2000 populations from U.S. Census Bureau
Note: NJSCR follows the SEER multiple
primary rules; thus a patient with cancer can
be counted more than once if diagnosed with
two or more primary cancers.
New Jersey Cancer Incidence by County,
1996-2000 – Hispanic Algorithm

used the NAACCR Hispanic Identification
Algorithm (NHIA)
 auguments the cases reported as Hispanic
 based on:
– birthplace
– marital status
– race
– surname match to the 1990 U.S. Census
Hispanic surname list
County Cancer Incidence Tables and
Figures – General Information
includes the 7 cancers in the CCCP – breast,
cervix, colorectal, lung & bronchus,
melanoma, oral cavity & pharynx, prostate
 include incidence rates and stage at
diagnosis by race, ethnicity, and age group
for:

– men and women for colorectal, lung & bronchus,
oral cavity & pharynx cancers and melanoma of
the skin
– women only for breast, cervical cancer
– men only for prostate cancer
– except stage at diagnosis is not included for lung
& bronchus cancer
County Cancer Incidence Tables and
Figures – General Information (cont.)

incidence rates were calculated for invasive
cancers only
 incidence rates are per 100,000 population
and age-adjusted to the 2000 U.S. population
standard
 percents diagnosed by stage include invasive
and in situ cases except for cervical cancer
 for the percents diagnosed by stage the in
situ and localized stages are combined
except for breast cancer
Note: invasive cancers are localized, regional,
and metastatic stages; in situ cancers are not
considered invasive
County Cancer Incidence Tables and
Figures – General Information (cont.)





race categories are white, black, and all races
(includes other than white and black races
and unknown race)
ethnic category is Hispanic (non-Hispanic is
not shown)
race and ethnicity are not mutually exclusive
age groups are 15-39, 40-49, 50-64, 65-74,
75 and over (the 0-14 age group was not
included due to very small numbers
statewide)
counts, and rates based on counts, fewer
than 5 are suppressed due to unreliability
County Tables & Graphs
Cancer Incidence

use to determine opportunities for prevention
activities (and screening activities for
colorectal cancer)
 within the county compare rates among the
different gender, the different race and ethnic
groups and the different age groups
 compare the county rates to the New Jersey
rates
 be cautious with rates based on small
numbers:
– the number of people affected is small
– the rates are not reliable
Note: Corresponding incidence graphs for
men and women are on the same scale.
County Tables & Graphs
Cancer Incidence by Race and Ethnicity





table includes incidence counts and rates for
each year and 1996-2000 combined
separate table and graphs for each gender
where applicable
table includes all races, whites, blacks,
Hispanics for the county and New Jersey
first line graph shows annual incidence rates
for whites and blacks in the county and New
Jersey (if data for blacks is suppressed then
all races is shown instead)
second line graph shows annual incidence
rates for Hispanics in the county and New
Jersey
County Tables & Graphs
Cancer Incidence by Age Group

separate table and graphs for each gender
where applicable (New Jersey is shown
separately)
 table includes incidence counts and rates for
each year and 1996-2000 combined
 table includes five age-groups for the county
 line graph shows annual incidence rates by
age group
County Tables & Graphs
Stage at Diagnosis
use to determine screening needs – distant
stage is the most important stage to note
 within the county compare percent diagnosed
at the distant stage among the different race
and ethnic groups and the different age groups
 compare the percent diagnosed at the distant
stage in the county with New Jersey
 be cautious with percents based on small
numbers:
– the number of people affected is small
– the percents are not reliable

County Tables & Graphs
Stage at Diagnosis by Race and Ethnicity

separate table and charts for each gender
where applicable (New Jersey is shown
separately)
 table includes the number and percent of cases
diagnosed at each stage for 1996-2000
combined
 table includes all races, whites, blacks,
Hispanics for the county
 pie charts show the percent diagnosed by stage
for all races, whites, blacks, and Hispanics
 the dark pie slice is the distant stage, the stage
with the lowest survival rate
Note: Read the pie chart clockwise.
County Tables & Graphs
Stage at Diagnosis by Age Group

separate tables and graphs for each gender
where applicable (New Jersey is shown
separately)
 table includes the number and percent of cases
diagnosed at each stage for 1996-2000
combined
 table includes five age-groups for the county
(New Jersey is shown separately)

Comparison with Other Data Sources

Healthy New Jersey 2010:
– this county data is more recent
– age-adjusted rates computed using the
1970 U.S. population standard so cannot
compare with these county data rates*
 Cancer Control Planet:
– this county data is more recent
– Planet suppresses counts <16
– Planet does not include stage at diagnosis
*Currently, the 2000 U.S. population
standard is used nationwide.

Group Exercise





three groups (by color of your folder)
each group has one cancer type for one
county
discuss the data (e.g. compare incidence and
stage at diagnosis among the genders, races,
ethnicity and with New Jersey)
agree upon two or three prevention/early
detection activities and the target
population(s) for each based on the data
if time enough, each group report its findings
