California Teachers Study
In 1995 and 1996, 133,479 female teachers and public school professionals in California participated in a large prospective cohort study. Since then, through mailed questionnaires and biological samples, those women have offered information about their respective lifestyles, health and backgrounds.
This huge cache of data has allowed researchers to determine a set of differentiators between women who have developed cancer from those who have not.
Some of the most recent findings from the California Teachers Study include:
Obesity is related to an increased risk of pancreatic cancer
Small-particulate air pollution is related to the risk of death from cardiovascular disease
Smoking and secondhand smoke may increase the risk of non-Hodgkin's lymphoma
Delayed onset of puberty may be related to an increased risk of thyroid cancer in younger women
A decrease in invasive breast cancer is explained, in large part, by the decline in use of hormone therapy to treat menopausal symptoms
Now, in an expansion of the California Teachers Study, researchers are collecting blood and saliva samples from more than 20,000 cohort members with no history of any cancer. This large group of biospecimens — combined with data on diet, lifestyle and other factors — will help researchers identify new biomarkers for early detection, predict responses to treatments, and identify genetic and environmental interactions.
The new information could lead to better treatments and, perhaps, the prevention of cancer.
News about the California Teachers Study
Internationally renowned biostatistician and epidemiologist Leslie Bernstein, Ph.D., has been selected to receive the American Association for Cancer Research’s (AACR) 27th Annual American Cancer Society Award for Research Excellence in Cancer Epidemiology and Prevention for her outstanding research accomplishments.
Researcher James Lacey Jr., Ph.D., wants to pool data from the California Teachers Study and other studies to create a personalized prevention tool.
James Lacey, Jr., Ph.D., who now runs the California Teachers Study, is taking on the role of disruptor, as he transforms how study data is collected and shared.
Bridget Marshall, a former patient and current employee at City of Hope, one of the centers out of which the study is run, also has been a participant in the California Teachers Study for more than two decades.
City of Hope researcher, Leslie Bernstein, made a big splash in breast cancer research. Earlier, she helped launch the California Teachers Study, a seminal breast cancer study involving more than 133,000 teachers.
The California Teachers Study, a more than two-decade long study of more than 133,000 teachers, started in 1994, but its eventual principle investigator, Leslie Bernstein of City of Hope, was dreaming about making her mark -- and making a difference -- long before then.
City of Hope today announced that the National Cancer Institute (NCI) has awarded more than $12 million to City of Hope supporting the landmark California Teachers Study (CTS). The five-year NCI award will fund the CTS’s innovative approach of using secure, cloud-based data management and technology to conduct large-scale cancer epidemiology research.
