Predicting Response to Capecitabine in Women With Metastatic Breast Cancer
Multicentric Pilot Study of Dihydropyrimidine Dehydrogenase (DPD) Deficiency for Predicting Capecitabine Toxicity in Breast Cancer Patients

RATIONALE: Identifying genes that increase a person's susceptibility to side effects caused by capecitabine may help doctors plan better treatment.

PURPOSE: This clinical trial is studying blood samples in predicting response to capecitabine in women with metastatic breast cancer.

OBJECTIVES:

Primary

  • To determine the sensitivity, specificity, and positive and negative predictive values of dihydrouracil/uracil (UH_2/U) ratio measured before starting treatment on grade 3-4 capecitabine-related toxicity in women with metastatic breast cancer.

Secondary

  • To prospectively test the value of the germinal genotype of thymidylate synthase (TS) and methylenetetrahydrofolate reductase (MTHFR) as predictors of resistance to capecitabine.
  • To evaluate the practical feasibility of such pre-therapeutic screening.
  • To determine the sensitivity, specificity, and positive and negative predictive values of dihydropyrimidine dehydrogenase genotyping on grade 3-4 capecitabine-related toxicity in the first and second courses.
  • To evaluate the predictive gain provided by genotyping relative to phenotyping alone.
  • To evaluate the influence of TS and MTHFR gene polymorphisms on clinical response and duration of response.
  • To evaluate the pharmacokinetics of capecitabine and its metabolites and their relationship with UH_2/U and genotype.
  • To evaluate the total cost of pre-therapeutic phenotyping alone and the combination of phenotyping and genotyping.
  • To exhaustively analyze the 23 exons of the dihydropyrimidine dehydrogenase (DPYD) gene in patients who developed toxicity.

OUTLINE: This is a multicenter study.

Patients receive oral capecitabine twice daily on days 1-14. Treatment repeats every 21 days in the absence of disease progression or unacceptable toxicity.

Blood samples are collected 8-15 days before the start of treatment and periodically on the first day of treatment for dihydropyrimidine dehydrogenase phenotyping (dihydrouracil/uracil ratio and high performance liquid chromatography analysis), genotyping (4 most relevant single nucleotide polymorphisms), and pharmacokinetic analysis.
