Brief Summary
RATIONALE: Identifying genes that increase a person's susceptibility to second cancers may help the study of cancer treatment. PURPOSE: This study is looking at genetic susceptibility and risk of second cancers in patients who have undergone stem cell transplant for cancer.

Outcome Measures
Primary Outcomes (1)
Genetic susceptibility to the carcinogenic effects of radiotherapy, tobacco, and UV light and risk of second malignant neoplasms (SMN)
At study entry
Secondary Outcomes (3)
Radiation sensitivity in B-cell lymphoblastoid cells
At study entry
Allelic variants of genes involved in xenobiotics metabolism, DNA repair, and provision of nucleotide pool of patients with SMN compared to their first-degree relatives and patients without SMN
At study entry
Role of potentially carcinogenic environmental exposures (tobacco and sun light) pre- and post-HSCT in the risk of SMN
At study entry
Interventions
Eligibility Criteria
Patients who survived 100 days post-hematopoietic stem cell transplantation (HSCT)
You may qualify if:
- CASES are those who:
- Survived at least 100 days post-hematopoietic stem cell transplantation (HSCT).
- Developed an SMN after that time point.
- And received TBI as part of the preparative regimen.
- CONTROLS are randomly selected:
- In a 4:1 ratio to cases from the same cohort of 100 day + survivors of HSCT who received TBI.
- Controls will be matched to the cases by race and primary diagnosis.
- In addition, they must have survived for at least the elapsed time between the case's HSCT and the secondary cancer, without development of an SMN.
- We are matching on primary diagnosis, as genotype or radiation sensitivity may predispose to specific primary cancers, as well as the SMNs.
- We are matching on race, as allele frequencies vary widely across ethnic groups.
You may not qualify if:
- Did not survive at least 100 days post-hematopoietic stem cell transplantation (HSCT).
- Did not develop an SMN after that time point.
- Did not receive TBI as part of the preparative regimen.
