QOL data will be collected using the Functional Assessment of Cancer Treatment (FACT-C) instrument. The feasibility of collecting QOL data will be assessed and rates of missing data will be computed. Reasons for missing data will be characterized to the extent possible. In addition to this, QOL data will be described using mean, standard deviation, median, inter-quartiles and range as well as graphically. For exploratory analysis of QOL data over time we will examine the use of hierarchical linear models.
