Brief Summary:

RATIONALE: Breast-conserving surgery is a less invasive type of surgery for breast cancer and may have fewer side effects and improve recovery. Radiation therapy uses high-energy x rays to kill tumor cells. Giving radiation therapy after surgery may kill any tumor cells that remain after surgery.

PURPOSE: This phase II trial studies how well breast-conserving surgery and radiation therapy work in treating patients with multiple ipsilateral breast cancer


Condition or disease Intervention/treatment Phase
Breast Cancer Procedure: therapeutic conventional surgery Radiation: whole breast irradiation Phase 2

Detailed Description:

OBJECTIVES:

Primary

  • To assess the local recurrence (LR) rate with breast-conservation in patients with multiple ipsilateral primary breast cancer (MIBC).

Secondary

  • To examine the conversion rate to mastectomy secondary to persistent positive margins; poor cosmesis within the first year of attempting breast-conservation surgery (BCS) or inability to satisfy the radiation dose constraints on the boost to the lumpectomy bed of each site of disease.
  • To assess whether patients who did not undergo re-excision for close margins (< 2 mm) have a higher local recurrence (LR) rate than patients for whom negative margins were achieved.
  • To assess patient's perception of cosmesis and incidence of breast lymphedema.
  • To assess incidence of breast lymphedema
  • To examine the type and severity of adverse effects of breast conserving surgery and radiation for women with multiple ipsilateral primary breast cancer (MIBC).
  • To examine the radiation-related side effects of whole-breast radiation with a boost to 1 large or > 1 lumpectomy site.

OUTLINE: This is a multicenter study.

Patients undergo breast-conserving surgery (BCS) with all lesions resected to negative margins using 1 lumpectomy or 2-3 separate lumpectomy incisions at the discretion of the surgeon. Patients receive adjuvant chemotherapy and/or endocrine therapy at the discretion of the treating medical oncologist based on tumor characteristics.

Ages Eligible for Study:   40 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No
Criteria

Registration Inclusion Criteria:

  1. Age ≥ 40 years per National Comprehensive Cancer Network (NCCN) recommendations for breast conservation.
  2. Life Expectancy of at least 5 years, excluding diagnosis of breast cancer (Comorbid conditions should be taken into consideration, but breast cancer diagnosis is not a consideration)

  3. Female Gender - Men are excluded from this study. Male breast cancer is a rare event.

    Men are rarely candidates for breast conservation surgery due to small breast size. Men are less likely to be candidates for breast conservation surgery if found to have MIBC.

    Men are rarely candidates for breast conservation surgery due to small breast size. Men are less likely to be candidates for breast conservation surgery if found to have MIBC.

  4. Foci of Breast Cancer

    4.1 Upon clinical exam and pre-operative imaging by mammogram +/- MRI, two or three foci of biopsy proven breast cancer separated by > 2 cm of normal breast tissue.

    4.2 Foci must include at least one focus of invasive breast carcinoma with another focus of either invasive breast carcinoma or ductal carcinoma in situ (DCIS).

    No more than 2 quadrants with biopsy proven breast cancer.

    4.3 Note: The shortest distance between lesions must be reported on mammogram +/- MRI and eligibility criteria must be met on both, if both are obtained.

    4.4 Note: Patient is eligible for study if lesion is not visualized on all imaging modalities (i.e., any of the lesion(s) is/are visualized on MRI but not on mammogram OR visualized on mammogram but not on MRI).

    4.5 Ultrasound cannot be used to determine patient eligibility; eligibility to be determined by bilateral mammogram +/- MRI only.

    4.6 Fine needle aspirate of the second or third lesion to document malignancy is allowed if the first focus is shown to be invasive by core needle biopsy.

    4.7 Patient may remain on study if, upon pathological assessment, two or three lesions identified on pre-operative imaging represent one contiguous lesion.

  5. Patients may be registered AFTER surgery and PRIOR TO radiation therapy if either of the criteria is met:

    5.1 An area of atypia > 2cm from the index lesion excised at the time of cancer operation is upgraded to DCIS or invasive carcinoma thereby identifying MIBC. OR

    5.2 Patient underwent resection of two or three foci of malignancy by breast conservation surgery with a minimum of one invasive focus of breast cancer and a minimum of 2 cm of normal breast tissue between the lesions on final pathology.

  6. Mammogram Imaging - Bilateral mammogram ≤ 90 days prior to date of surgery.

    6.1 Note: For patients undergoing more than 1 breast operation, this is the date of the first breast surgery for breast cancer treatment.
