ClinicalTrials.gov Identifier:
NCT00478686
First received: May 23, 2007
Last updated: February 27, 2014
Last verified: February 2014
  Purpose

The goal of this laboratory research study is to identify possible differences in a gene among patients with breast cancer that cannot be treated by surgery. Researchers want to find out if differences in this gene may increase the risk of side effects from capecitabine.


Condition Intervention
Breast Cancer
Procedure: Phlebotomy

Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Retrospective
Official Title: A Retrospective Analysis of the Association of Dihydropyrimidine Dehydrogenase (DPYD) Variants With Toxicity Related to Capecitabine

Primary Outcome Measures:
  • Incidence of DPYD variants in patients [ Time Frame: 2 Years ] [ Designated as safety issue: No ]

Biospecimen Retention:   Samples With DNA

5 to 7.5 milliliter (mL) sample of blood. Alternatively, DNA will be extracted from 10um slices of formalin-fixed paraffin-embedded tissue from previously collected tumor tissue (from the time of the breast cancer diagnosis).


Estimated Enrollment: 210
Study Start Date: May 2007
Estimated Primary Completion Date: May 2016 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Severe Toxicity
Patients who experienced severe toxicity (at least one grade 4 side effect) with capecitabine chemotherapy
Procedure: Phlebotomy
5 to 7.5 milliliter (mL) Blood Sample
Dose-Limiting Toxicity
Patients who experienced dose-limiting toxicity (at least one grade 3, or recurrent grade 2, side effect)with capecitabine chemotherapy
Procedure: Phlebotomy
5 to 7.5 milliliter (mL) Blood Sample
Low/No Toxicity
Patients who have experienced low/no toxicity (none or only side effects at grade 1 & 2) with capecitabine chemotherapy.
Procedure: Phlebotomy
5 to 7.5 milliliter (mL) Blood Sample

Detailed Description:

If you agree to take part in this study, 1 blood sample (about 2 tablespoons) will be drawn for use in genetic research.

If you are unable to provide a blood sample, researchers will collect leftover tissue samples from your previously collected tumor tissue (from the time of the breast cancer diagnosis). The tumor samples will be used for genetic research.

After the blood draw or tissue collection, your participation in this study will be over.

The blood samples for the genetic research will be stored at Myriad Laboratories. Before your blood and/or tissue is sent to Myriad Laboratories for banking, your name and any personal identifying information will be coded to protect your privacy. M. D. Anderson will not have oversight of any leftover tissue and/or blood that will be banked by Myriad Laboratories for additional research.

This is an investigational study. Up to 210 patients will take part in this study. All will be enrolled at M. D. Anderson.
