About

RATIONALE: The timing of breast cancer surgery within the menstrual cycle may affect outcome. It is not yet known if treatment is more effective during the initial or final phase of the menstrual cycle.

PURPOSE: Phase III trial to determine the effect of menstrual cycle phase at surgery in treating premenopausal women who have stage I, stage II, or stage III breast cancer.

Full description

OBJECTIVES:

• Determine if the timing of breast surgery during the menstrual cycle impacts disease recurrence, progression, or death among different racial groups in premenopausal women with stage I, II, or III breast cancer.
• Determine if definitive breast cancer surgeries (e.g., lumpectomy or mastectomy) performed during the follicular phase result in poorer prognosis (recurrence, disease progression, or death) compared with surgeries performed during the midcycle or luteal phases in this patient population.

OUTLINE: This is a multicenter study.

Patients undergo either fine needle aspiration concurrently with definitive breast surgery (mastectomy or lumpectomy) or needle-directed excisional biopsy followed by definitive breast surgery.

Patients undergo serum collection for hormonal analysis preoperatively, 24 hours post operatively, at days 7 and 14, and at 3 months and urine collection for hormonal analysis beginning 24 hours prior to surgery and continuing daily until the onset of the next menses.

Patients complete a 30-minute telephone interview regarding medical, family, occupational, and reproductive history and lifestyle habits (e.g., diet, exercise, or environmental exposures). Beginning 24 hours prior to surgery and continuing until the onset of the next menses, patients complete a menstrual cycle journal indicating the start and length of menses.

Patients undergoing mastectomy are followed every 3 months for 1 year, every 6 months for 1 year, and then annually thereafter. Patients undergoing adjuvant therapy are followed every 3 months for 3 years and then every 6 months thereafter or every 4 months for 2 years and then every 6 months thereafter.

PROJECTED ACCRUAL: Approximately 400 patients will be accrued for this study within 2.5 years.
