 We will enroll 40 individuals, randomizing half to receive propranolol and half to serve as the control group not on the study drug. Study participants will start propranolol three weeks prior to their transplant and continue it until 30 days after the transplant. We will explore the effect of socioeconomic status, depression, and anxiety on individuals gene expression response to propranolol with the idea that the more impoverished, anxious, or depressed individuals will display an even greater change in their gene expression. Part of the purpose of this study is also be to assess whether it is feasible to give this drug to individuals with cancer. Results of this study may inform larger trials assessing the effects of propranolol on cancer progression.
