  Purpose

RATIONALE: Timing of breast cancer surgery may improve effectiveness of treatment and may help patients live longer.

PURPOSE: Clinical trial to determine whether timing of primary surgery in relation to menstrual cycle is associated with disease-free survival 5 years after surgery in women who have stage I or stage II breast cancer.

Detailed Description:

OBJECTIVES:

  • Document menstrual phase (follicular vs luteal) by circulating hormones and menstrual history at the time of primary surgery in premenopausal women with stage I or II breast cancer.
  • Correlate menstrual phase at primary surgery with 5-year disease-free survival in these patients.
  • Compare the menstrual cycle data obtained by hormone levels and study-specific menstrual cycle history with information recorded in the general written record.
  • Compare the menstrual cycle data (e.g., hormone levels and cycle history) for these women with the data for the general population.
  • Estimate the disease-free survival of women who undergo a 2-stage surgical procedure with cancer found at both stages when the surgery is not confined to the same menstrual cycle phase.

OUTLINE: This is a multicenter study.

Hormone levels and menstrual history are obtained within one calendar day to surgery.

Patients undergo either one- or two-stage surgery (open biopsy followed immediately or later by mastectomy or breast-conserving surgery).

Patients complete a questionnaire 6 months after surgery to assess the extent of adjuvant therapy received (if any) and a questionnaire 12 months after surgery to assess recurrence of breast cancer and vital status.

Patients are followed annually for 10 years.

PROJECTED ACCRUAL: A total of 1,100 patients will be accrued for this study within 5 years.
