Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages Any age
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Study population: Patients who survived 100 days post-hematopoietic stem cell transplantation (HSCT)

Who may be able to join

  • 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.
Show all 10Show fewer
  • 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.

Who cannot join

  • 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.

About this study

Official title: Radiation Sensitivity, DNA Repair, and Second Cancers.

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.

Read the detailed description

OBJECTIVES:

Primary

  • Determine whether genetic susceptibility (e.g., inherited differences in radiation sensitivity to normal tissue or genes of xenobiotic metabolism, nucleotide provision, or DNA repair) to the carcinogenic effects of radiotherapy, tobacco, and UV light modifies the risk of second malignant neoplasms (SMN) in patients with cancer treated with hematopoietic stem cell transplantation (HSCT).

Secondary

  • Measure inherent sensitivity to radiotherapy via G_2 chromosome radiation sensitivity assay using B-cell lymphoblastoid cell lines derived from pre-HSCT cryopreserved peripheral blood mononuclear cells of patients with and without SMN.
  • Measure the frequency of allelic variants of genes involved in xenobiotics metabolism, DNA repair, and provision of nucleotide pool and compare the frequencies among patients with and without SMN, determine the transmission of specific alleles of these genes from parents to patients, and correlate allelic variants of DNA repair and nucleotide provision in genes with in vitro radiation sensitivity.
  • Evaluate the role of potentially carcinogenic environmental exposures (tobacco and sun light) pre- or post-HSCT in the risk of SMN and examine the association of these exposures with SMN and the interaction of these exposures with allelic variants of genes involved in xenobiotic metabolism, nucleotide provision, and DNA repair.

OUTLINE: Patients complete self-reported questionnaires and medical records are reviewed to collect information on UV light and tobacco exposure pre- and post-transplantation. Information is analyzed for association with second malignancy neoplasms.

Blood samples are collected from patients pre-hematopoietic stem cell transplantation and from their parents (when available) or other first-degree relatives for genetic biomarkers of susceptibility to second malignancies, DNA repair and provision nucleotide, genetic susceptibility to toxicity from combined cancer therapies, and environmental carcinogens.

PROJECTED ACCRUAL: A total of 1,000 patients (800 patients without second malignant neoplasms [SMN] and 200 patients with SMN) will be accrued for this study.

Questions about this trial

What is this clinical trial studying?

An observational study of Cancer, run by Vanderbilt-Ingram Cancer Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 16 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: Low accrual). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Genetic susceptibility to the carcinogenic effects of radiotherapy, tobacco, and UV light and risk of second malignant neoplasms (SMN) (time frame: At study entry). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Aug 2018.
