A011106

Alternate approaches for clinical stage II or III Estrogen Receptor positive breast cancer Neoadjuvant Treatment (ALTERNATE) in postmenopausal women

The study is being conducted to determine whether neoadjuvant endocrine therapy with fulvestrant or the combination of anastrozole and fulvestrant, is better than anastrozole when given before surgery to shrink the cancer. Anastrozole inhibits tumor growth by reducing the levels of estrogen and has been approved by the Food and Drug Administration (FDA) of the United States for use after surgery for postmenopausal women with estrogen receptor positive breast cancer. It is also considered a standard of care to give anastrozole for a few months before surgery to shrink the tumor. Fulvestrant inhibits tumor cell growth by reducing the levels of estrogen receptor in the tumor cell. It is not approved by the FDA for use in women with early stage breast cancer before or after surgery, but is approved by the FDA for patients with advanced (Stage 4) estrogen receptor positive breast cancer that has spread to other parts of the body.

Key Inclusion Criteria

  • Postmenopausal women
  • Clinical T2-T4c, any N, M0 invasive breast cancer
  • Invasive breast cancer is ER+ with an Allred score of 6, 7, or 8 and HER2 negative
  • Must agree to undergo the required research biopsies at baseline, week 4 and at surgery.

Exclusion Criteria

  • An excisional biopsy of this breast cancer
  • Surgical axillary staging procedure prior to study entry [Note: FNA or core needle biopsy of axillary node is permitted]
  • Treatment for this cancer including surgery, radiation therapy, chemotherapy, biotherapy, hormonal therapy or investigational agent prior to study entry
  • History of invasive breast cancer or contralateral DCIS
  • Multifocal invasive breast cancer (defined as >5cm between invasive lesions)

AFT-25

Comparison of Operative to Monitoring and choice of Endocrine Therapy (COMET) Trial for Low Risk DCIS: A Phase III Prospective Randomized Trial

The COMET Trial is designed to assess outcomes with a less aggressive approach to the management of DCIS, and to continue to advance the knowledge regarding the biologic behavior of DCIS.

COMET is a prospective randomized trial that will assess the risks and benefits associated with active surveillance (AS) versus guideline concordant care (GCC) for patients with low-risk DCIS (Figure 1). The overarching hypothesis of the study is that management of low-risk DCIS using an active surveillance approach (without surgical resection) does not yield inferior oncologic or quality of life outcomes when compared with guideline concordant care (which includes surgical resection of the DCIS +/- radiation).

COMET Trial Schema

COMET Trial Schema

Patients in the active surveillance group will be followed with mammography every six months to assess for invasive progression. The guideline concordant care group will be treated with surgery, radiation, or a combination according to usual care guidelines. Endocrine therapy will be optional in both groups. 

Inclusion in the COMET Trial will be limited to women ages 40 and older who present with a new diagnosis of DCIS grades I/II. DCIS must be estrogen receptor (ER)-positive and/or progesterone receptor (PR)-positive. If human epidermal growth factor receptor 2 (HER2) testing is performed, the DCIS must be HER2 0, 1+, or 2+ by immunohistochemistry (IHC). Male patients, patients with bloody nipple discharge, pregnant patients, or patients with documented history of prior tamoxifen, aromatase inhibitor, or raloxifene use will be excluded. Results from this study will help to determine whether de-escalation of treatment for low-risk DCIS is a feasible approach, and how clinical outcomes and quality of life compare between treatment and surveillance groups.

This trial will recruit 1,200 patients at 100 sites and is open for enrollment.
