InterCHANGE Objectives

The main objectives of the interCHANGE project are:

  • Recruit a large series of 2000 cases and 2000 control participants in order to ensure accurate and robust findings;

  • Apply a shortened lifestyle questionnaire to obtain essential information;

  • Obtain high-quality biological samples (blood sample from both cases and controls, tumour tissue from cases);

  • Interview cases when they return for an annual check-up and obtain a blood sample; and

  • Prospectively obtain treatment data, as well as relapse and survival information.
