Metabolic Genotypes and Oncogenic Damage in Breast Cancer
Metabolic Genotypes and Oncogenic Damage in Breast Cancer
RATIONALE: Studying samples of urine and blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.
PURPOSE: This study is looking at urine and blood samples in women with newly diagnosed breast cancer.
OBJECTIVES:
OUTLINE: Urine and blood samples are collected for DNA, mutation, and polymorphism analysis. The biological samples may be stored and used for future research.
Patients complete a Baseline Questionnaire to collect basic risk/exposure information, including demographic factors (e.g., age, weight, height, and body mass index), menstrual/reproductive history, medical history, medication use, smoking history, alcohol consumption, exposure to chest x-ray, and family history of breast cancer in first-degree relatives. Patients also complete a Second Hand Smoke Questionnaire to collect information on cigarette smoking history and second hand smoke exposure and a Food Frequency Questionnaire to collect information on the frequency of use of specific fruits and vegetables (e.g., cruciferous vegetables) and to estimate usual dietary intake of 33 nutrients during the past year (e.g., total fat, saturated fat, oleic fat, linoleic fat, carbohydrates, protein, vitamins [e.g., A, B1, B2, niacin, B6, folate, C, and E], minerals [e.g., calcium, magnesium, iron, and zinc], electrolytes [e.g., sodium and potassium], and dietary fiber). Patients' medical charts are also reviewed to collect information on age, gender, ethnic background, medical history, and medical care.
