- Subject is able (i.e. sufficiently fluent) and willing to complete the Quality of Life (EORTC QLQ C-30 and Trial Specific Checklist) in English or French. The baseline assessment must already have been completed at the time of enrollment. Inability (illiteracy in English or French, loss of sight or other equivalent reason) to complete questionnaires will not make the patient ineligible for the study; however, ability but unwillingness to complete the questionnaires will make the patient ineligible. (Once the target number of 888 subjects is achieved, this criterion will no longer need to be fulfilled.) [See Appendix VI]. Sub-set enrollment completed 2011NOV04.
