Cancer Statistics

Trends by Race and ethnicity 1976-2012

This report provides physicians, researchers, public health officials and the public with high quality data documenting the trends of many different types of cancer in Los Angeles County over thirty years. These data illustrate considerable differences in cancer incidence between men and women and among various racial/ethnic groups in a way not previously available to our community. These differences not only identify the types of persons at greater and lesser risk of each cancer but also offer intriguing clues that may lead to better understanding and prevention of cancer.

Trends Among Adolescents and Young Adults 1988-2011

For each type of cancer, the AYA survival information is analyzed by sex, age, race/ethnicity, socioeconomic, and stage of disease at diagnosis. The goal is to provide a better understanding of the effectiveness of cancer treatment and help to identify subgroups of AYAs who are at greatest risk of cancer related death, in order to facilitate the advancement in AYA cancer research.

Survival Among Adolescents and Young Adults 1988-2014

Leveraging the large and diverse population of Los Angeles County, this report provides cancer survival probabilities for 18 types of cancer diagnosed among Adolescents and Young Adults (AYAs) aged 15-39 years old.

Cancer in Los Angeles County, Bibliography 1972 – to Present

A compendium of the published scientific research based on the CSP. Much of the hard work represented in this volume was performed by the many scientists whose names are listed. Each citation typically required years of work, from developing a hypothesis, writing a compelling research proposal and collecting and analyzing the research data before the published report could be prepared.

A statistical method allowing comparisons of populations that takes into account age-distribution differences between populations. Most incidence and death data in SEER are age-adjusted, although some tables, in contrast, present the crude rate.

The rate of incidence or mortality of a specific age group, calculated per 100,000 people.

A crude rate is the ratio of the number of people in which the event of interest happens in a specified time period to the size of the population who may experience this event during the same time period. There are no adjustments made when a crude rate is given.

The percentage of people in a study or treatment group who are alive five years after they were diagnosed with or treated for a disease, such as cancer. The disease may or may not have come back.

The ratio of the number of new cancers of a specific site/type occurring in a specified population during a year to the number of individuals who were at risk for the given cancer, generally expressed as the number of cancers per 100,000 persons.

The Surveillance, Epidemiology, and End Results (SEER) Program of the NCI is a collection of central cancer registries in the United States that collect and submit cancer incidence, prevalence, mortality, survival, stage at diagnosis data and other statistics to the National Cancer Institute. The National Cancer Act of 1971 mandated the collection, analysis, and dissemination of data useful in the prevention, diagnosis, and treatment of cancer leading to the establishment of the SEER Program.

A standard population for a geographic area, such as the US or the world, is a table giving the proportions of the population falling into the age groups 0, 1-4, 5-9, … , 80-84, and 85+.

Data that is used to monitor changes in cancer in a population. Included are measures of cancer incidence, morbidity, survival, prevalence and mortality. Also included are the assessment of genetic predisposition, environmental and behavioral risk factors, screening practices, and the quality of care from prevention through palliation.
