Figure 1

Illustration of traditional epidemiology (A), traditional molecular pathology (B), and molecular pathologic epidemiology (C). Note that molecular pathology plays a central role in molecular pathologic epidemiology. Molecular pathologic epidemiology addresses a question whether a particular exposure factor is associated with a specific molecular change in colorectal cancer (C, left side), as well as a question whether a specific molecular change can interact with a particular exposure factor to affect tumor cell behavior (C, right side). The latter represents a new direction of molecular pathologic epidemiology where results can provide additional insights on mechanism of how the tumoral molecular change and the exposure factor of interest influence tumor cell behavior.
