Brief Summary: RATIONALE: Studying samples of blood in the laboratory from patients with cancer may help doctors learn more about nausea and vomiting caused by cancer treatment.
PURPOSE: This laboratory study is looking at blood samples from patients with cancer who were treated on a clinical trial to control nausea and vomiting during donor stem cell transplant.
Detailed Description: OBJECTIVES:
Primary
* To compare the amount of substance P in serum samples from patients with cancer treated with busulfan/cyclophosphamide or cyclophosphamide/total body irradiation conditioning regimens prior to undergoing allogeneic hematopoietic stem cell transplantation.
Secondary
* To assess the changes in substance P over time to see if there is an optimal time shown by this physiologic correlate to discontinue substance P blockade after the chemotherapy regimen is completed in these patients.
OUTLINE: Previously collected serum samples are analyzed by enzyme immunoassay for changes in substance P levels.
Patients' medical records are reviewed for demographic information, past history, and course of treatment.
