Research plans for the CLEAR Study at Cancer Council NSW

The NSW CLEAR Study has collected data from over 10,800 people with and without cancer to provide a better understanding of the genetic and environmental causes of cancer in NSW. This information is now available to the cancer research community (subject to appropriate scientific and ethical approval).

Scientists at Cancer Council NSW are using CLEAR questionnaire data and blood samples to evaluate risk factors for cancer. Particular areas of interest are links between cancer and:

  • Smoking
  • Infectious agents
  • Hormones (exogenous and endogenous)
  • Sun exposure, and sleep patterns
  • BMI/physical activity
  • Alcohol
  • Tooth loss

We are also interested in cancer in immigrant populations compared with people who are Australian born.

CLEAR Collaborations

We invite researchers to join us for a discussion about possible collaborative projects. At CCNSW we are particularly interested in collaborations which can bring expertise outside our areas of content knowledge, such as laboratory science. New collaborators are welcome.

It should be noted that The CLEAR Study is an open resource. Scientists may apply to use questionnaire data and blood samples for any cancer research project, subject to scientific and ethical approval, without collaboration with Cancer Council NSW.

CCNSW is currently working towards linkage with Medicare records for CLEAR Study participants. This linkage will generate the potential for health services research, together with other planned record linkages.

Comparative analyses can be conducted using questions from 45 and Up Study, Skin Health Study and Cervical Health Study.

Thank you to all the people who have taken part in CLEAR.

Their questionnaire data and blood samples will help us understand risk factors for cancer in NSW.

“Many people think the only way to help research is to give a financial donation, but when it comes to a broad reaching study such as CLEAR, we’re totally reliant on the courage and goodwill of cancer patients in the community.”

“We have an enormous diversity of lifestyles: we can compare and get meaningful answers about the causes of cancer”
