OBJECTIVES:
Primary
* Describe the distributions of physiologic, psychosocial, and behavioral response to stress in women with newly diagnosed breast cancer.
* Describe the patterns of diurnal cortisol rhythms in women newly diagnosed with breast cancer.
Secondary
* Determine if diurnal salivary cortisol (mean or pattern) is consistent over two days within two weeks of study entry.
* Assess the changes in diurnal cortisol rhythm pattern and night-time urinary epinephrine excretion change after an intervening stress event (pre- to post-surgery).
* Determine if the diurnal cortisol rhythm and the night-time urinary excretion correlate with a variety of self-reported psychosocial factors: optimism (LOT-R), state and trait anxiety (STAI form Y-2), positive and negative affect (PANAS), depressive symptoms (CES-D), coping (Brief COPE), and perceived stress (PSS-10).
* Determine if the diurnal cortisol rhythm and the night-time urinary epinephrine excretion correlate with socioeconomic stress and discrimination (functional social support and discrimination \[EOD\]).
* Determine if the diurnal cortisol rhythm and the night-time urinary epinephrine excretion correlate with one lifestyle behavior and dietary fat consumption (Block food screener).
OUTLINE: Patients are stratified according to race (Caucasian vs African American).
Patients are instructed to collect saliva and urine samples on 2 separate days, within 2 weeks of study enrollment. Saliva samples are collected 6 times a day at baseline, before breast cancer surgery, and 7-10 days after surgery. Urine samples are collected after midnight until and including the first morning sample on the saliva-collection days.
Patients also complete questionnaires (either by telephone interview or in person) within 2 weeks of study enrollment and 7-10 days after breast surgery. Stress measures examined include optimism (LOT-R), trait-anxiety scale (STAI form Y-2), functional social support, affect and depression (PANAS and CES-D), perceived stress (PSS-10), economic hardship scales, discrimination (EOD), coping mechanisms (Brief COPE), and dietary fat consumption (Block Sugar/Fat/Fruit/Vegetable screener).
