Course Grade
Letter grade:
For the letter grade, A, B, or C will be assigned according to percentiles and the distribution
curves of the scores by students.
Each week, 1-3 readings for next lecture will be handed out. Students will be expected to read
these papers.
Course Description
To introduce students to basic concept in molecular epidemiology of cancer, including molecular
biology in epidemiology, selection, evaluation, and validation of biological markers, Design
considerations statistical methods in molecular epidemiology. We will discuss practical issues
such as biologic specimen collection, transportation, process and banking. The measurements
and methodological issues of three major biological markers including exposure marker,
susceptibility markers, and earlier biological response markers will be discussed.
To introduce basic concepts and methodology of molecular epidemiology of cancer, and to
review current molecular epidemiologic research of cancer in recent medical and epidemiological
literature. S/U or letter grade.
