Which U.S. national program collects population-based cancer incidence and survival data from registries across the country?
Answer: SEER (Surveillance, Epidemiology, and End Results)
SEER, maintained by NCI, is the premier population-based program collecting cancer incidence and survival data from geographically diverse U.S. registries.
Cancer incidence rate is calculated per how many persons in standard epidemiologic reporting?
Answer: 100,000 persons
Cancer incidence and mortality rates are conventionally expressed per 100,000 persons in the population to allow meaningful comparison across groups.
What does age-adjusted (age-standardized) cancer rate allow researchers to do?
Answer: Compare rates across populations with different age distributions
Age-adjustment removes the confounding effect of age so that rates in populations with different age structures can be validly compared.
The five-year relative survival rate compares observed survival of cancer patients to the survival of which comparison group?
Answer: A matched general population of the same age, sex, and race
Relative survival divides observed survival in cancer patients by expected survival in a demographically matched general population to isolate the cancer's impact.
Which term describes the total number of persons living with a cancer diagnosis at a given point in time?
Answer: Prevalence
Prevalence measures the total existing cancer case burden in a population at a specific time, combining new and existing survivors.
NPCR, managed by the CDC, primarily funds which type of cancer registries?
Answer: State and territorial central cancer registries
NPCR provides funding and standards to state and territorial central cancer registries to ensure complete, high-quality population-based cancer data nationwide.
