RATIONALE: Genetic testing for a specific enzyme may help doctors determine whether side effects from or response to chemotherapy are related to a person's genetic makeup. PURPOSE: Genetic trial to determine whether different forms of the UGT1A1 gene are related to the body's ability to break down drugs and to the gastrointestinal side effects seen in patients previously treated with flavopiridol.
OBJECTIVES: * Determine the relationship between UGT1A1 genotypes and drug pharmacokinetics and occurrence of gastrointestinal toxicity in cancer patients previously treated with flavopiridol on protocol NCI-97-C-0171C. OUTLINE: Genomic DNA from pre-existing samples of serum or plasma from each patient is analyzed for UGT1A1 gene by polymerase chain reaction and DNA sequencing. Results are then analyzed for a possible association between UGT1A1 genotypic variation and susceptibility to flavopiridol. Patients do not receive the results of the genetic testing, and the results do not influence the type or duration of treatment. PROJECTED ACCRUAL: A total of 50 patients will be accrued for this study.
