Methods: In order to answer the study questions, subjects will be assessed several times during the study period. The study involves a multidisciplinary group that will be evaluating and following the subjects. A baseline will be established by a physician and a nutritionist before the subjects start the high-dose chemotherapy regimen. The subjects will be followed with oral evaluations 3 times per week, beginning on the day of the transplant and ending when mucositis resolves, or the patient is discharged home, or 30 days post-transplant, whichever occurs first. At day 15 post-transplant, patients will be evaluated for the second time by the nutritionist. Further information such as blood values, use of medications and treatment complications, will be obtained by daily chart review.
