Hormone Therapy Or Chemotherapy Before Surgery Based on Gene Expression Analysis in Treating Patients With Breast Cancer

Completed · Not applicable

Conditions studied: Ductal Breast Carcinoma in Situ, Lobular Breast Carcinoma in Situ, Stage II Breast Cancer, Stage IIA Breast Cancer, Stage IIB Breast Cancer, Stage IIIA Breast Cancer, Stage IIIB Breast Cancer

In brief

This randomized pilot clinical trial studied whether the Oncotype DX gene expression "Recurrence Score" (RS) would be useful for helping make a decision about which type of pre-operative treatment, hormone therapy or chemotherapy would be a better for patients with hormone responsive cancers that were not suitable for breast conserving surgery. The RS is currently used to predict the risk of distant recurrence and the benefit of the addition of chemotherapy to hormonal therapy in the adjuvant setting.

Who can join

Age: 18 and older. Sex: female. Healthy volunteers: not accepted.

You may qualify if…

• The treating surgeon must determine that breast conservation therapy (BCT) would be made more feasible by reducing tumor size using neoadjuvant systemic therapy
• The patient must have signed and dated an institutional review board (IRB) approved consent form that conforms to federal and institutional guidelines
• The patient must be female
• The patient must be greater than or equal to 18 years old
• The patient must have an Eastern Cooperative Oncology Group Score (ECOG) performance status of 0 or 1
• The diagnosis of invasive carcinoma of the breast must have been made by core needle biopsy
• The primary breast tumor must be >= 2 cm by physical exam or imaging
• Ipsilateral axillary lymph nodes must be evaluated by imaging (MRI or ultrasound) within 6 weeks prior to randomization; If indicated for abnormal lymph nodes, fine needle aspirate (FNA) or core biopsy must be performed.
• The tumor must have been determined to be HER2-negative as follows:
• Fluorescent in situ hybridization (FISH)-negative (defined by ratio of HER2 to Chromosome 17 centromere (CEP17) must be < 2.2) or, if a ratio was not performed, the HER2 gene copy number must be < 4 per nucleus; or
• Chromogenic in situ hybridization (CISH) is performed, the result must indicate a HER2 gene copy number of < 6 per nucleus; or
• Immunohistochemistry (IHC) 0-1+; or
• IHC 2+ and FISH-negative or CISH-negative
• The tumor must have been determined to be ER+ and/or progesterone positive (PgR+) defined as > 10% tumor staining by immunohistochemistry
• The patient must have been evaluated by a treating physician, reviewed and discussed by the multi-disciplinary breast team, and considered to be a candidate for chemotherapy

You may not qualify if…

• FNA alone to diagnose the primary tumor
• Excisional biopsy or lumpectomy performed prior to randomization
• Surgical axillary staging procedure or sentinel node (SN) biopsy performed prior to registration
• Tumors clinically staged as including inflammatory breast cancer
• Ipsilateral cN2b or cN3 disease (patients with cN1 or cN2a disease are eligible)
• Definitive clinical or radiologic evidence of metastatic disease (Note: chest imaging [mandatory for all patients] and other imaging [if required] must have been performed within 6 weeks prior to randomization)
• Synchronous or metachronous contralateral invasive breast cancer; (patients with synchronous and/or metachronous contralateral ductal carcinoma in situ (DCIS) or lobular carcinoma in situ (LCIS) are eligible)
• HER2 test result of IHC 3+, regardless of FISH results, if performed
• Any history of ipsilateral invasive breast cancer or ipsilateral DCIS if treated with radiation therapy (RT); (patients with synchronous or metachronous ipsilateral LCIS are eligible)
• History of non-breast malignancies, except for in situ cancers treated only by local excision and basal cell and squamous cell carcinomas of the skin, within 5 years prior to randomization
• Treatment including RT, chemotherapy, and/or targeted therapy for the currently diagnosed breast cancer prior to registration
• Cardiac disease (history of and/or active disease) that would preclude the use of chemotherapy
• Pregnancy or lactation at the time of randomization; (Note: pregnancy testing must be performed within 2 weeks prior to randomization for women of childbearing potential)
• Other non-malignant systemic disease that would preclude the patient from receiving study treatment or would prevent required follow-up
• Psychiatric or addictive disorders or other conditions that, in the opinion of the investigator, would preclude the patient from meeting the study requirements
• Use of any investigational product within 30 days prior to registration
