Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 100 years
  • Women only
  • No healthy volunteers
  • Adult, Older adult

Study population: The primary objective of the study is to characterize the distribution of invasive breast cancer stage II or III by immunohistochemistry and gene expression profiles in Latin American women. The study has two parts: Part A is a descriptive, observational part to characterize the molecular profile of breast cancer in Latin American women; Part B, the standard neoadjuvant chemotherapy treatment part of the study, seeks to identify any associations between response to neoadjuvant therapy and the molecular profiles. Participants will be followed for a period of 5 years to determine any associations between the molecular profiles and disease evolution following standard treatment.

Who may be able to join

  • Women age greater than or equal to 18 years.
  • AJCC 7 clinical stage II or III breast cancer. Clarification: Participants with clinical stage II breast cancer who are later classified as histologically-confirmed stage I will remain on study; participants who are later classified as histologically-confirmed stage IV breast cancer will be taken off study.
  • Biopsy-accessible breast tumor or participant candidates for primary surgery.
  • Eastern Cooperative Oncology Group (ECOG) performance status 0 1.
  • Histologically confirmed new primary adenocarcinoma of the breast AJCC 7 clinical stage II or III. All histological types are included Hormone status: Any tumor ER/PgR status, any HER2/neu status as measured by local hospital pathology laboratory following US LA CRN standard operating procedures (SOPs).
  • Normal organ and marrow function as defined below:

  • Absolute neutrophil count greater than or equal to 1500/microL
  • Platelets greater than or equal to 100,000/microL
  • Total bilirubin within normal institutional limits, unless participant has Gilbert s disease, for which bilirubin must be less than or equal to 2.0 times upper limits of normal (ULN)
  • AST serum glutamic-oxaloacetic transaminase (SGOT)/ALT serum glutamic-pyruvic transaminase (SGPT) less than or equal to 1.5 times institutional ULN

  • Negative serum or urine beta-human chorionic gonadotropin (HCG), unless participant is post-hysterectomy or menopausal.
  • -Latin American women with breast cancer of all ethnic backgrounds will be included in this study as participants. There are no expected racial/ethnic differences in the recruitment effort.

Who cannot join

  • Prior history of non-breast malignancy (excluding in situ cancers treated only by local excision and basal cell and squamous cell carcinomas of the skin) within 5 years prior to enrollment in this study.
  • Bilateral invasive or in-situ breast cancer.
  • Inflammatory breast cancer.
  • Clinical or radiological evidence of distant metastases by computed tomography (CT), chest X-ray, abdominal/thoracic ultrasound, bone scan, and/or liver function tests including total bilirubin, alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP), within ranges defined in eligibility criteria for Part B of the study.
  • Prior hormone therapy, chemotherapy, biologic, targeted therapies, or radiation therapy for this malignancy. Prior bisphosphonate therapy is allowed.
  • Pregnant and lactating women: Effects on a developing human fetus of chemotherapeutic agents at the recommended therapeutic dose remain incompletely defined. For this reason and because these agents may be teratogenic, women of child-bearing potential must agree to use adequate contraception (double barrier methods of birth control or abstinence) prior to study entry and for the duration of study treatment phase. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her study physician immediately.

  • Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with chemotherapeutic agents, women who are breastfeeding will be excluded. If a participant is of child-bearing potential (women are not considered of childbearing potential if they are at least 2 years postmenopausal and/or surgically sterile), she must have documented negative serum or negative urine pregnancy tests within 14 days of entry to the study (i.e., within 14 days of signing the informed consent document).
  • Subjects with psychiatric illness and/or other specific situations that would limit compliance with study requirements and compromise participant follow-up.
  • Lack of ability to understand and willingness to sign a written informed consent document.
  • Note: Subjects who were enrolled prior to this amendment will be considered eligible even if the HIV/Hep C and pregnancy test were not preformed due to each country standards.
  • ELIGIBILITY CRITERIA FOR PART B OF THE STUDY:
  • Participants, who successfully enrolled into the first part of the study and who, according to local institutional guidelines, are candidates for neoadjuvant chemotherapy will participate in Part B of the study. Participants must also meet the inclusion and exclusion criteria described below.
  • Uncontrolled or severe cardiac disease. Baseline left ventricular ejection fraction (LVEF) by nuclear imaging or echocardiography must be within normal institutional limits.
  • Use of any investigational agents within 30 days of starting standard chemotherapy treatment.
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to chemotherapeutic agents or accompanying supportive medications.
  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness and/or other specific situations that would limit compliance with study requirements and compromise participant follow-up.

Objective:

  • To learn more about the biology and genetics of breast cancer in Latin American women.

Eligibility:

  • Latin American women age 18 and older of all ethnic backgrounds who have clinical stage II or III breast cancer. They must still be active and able to self-care.

Design:

  • Participants are only agreeing to have extra tissue or blood samples collected. They are also letting tissue left over from surgery be used for research. No procedures outside of standard care will be done.
  • Participants may have a medical history, physical exam, and blood tests. They may have a pregnancy test. They may have an ultrasound, mammogram, and other scans. They may have an intravenous needle placed in an arm vein.
  • Participants may have a core biopsy. For this, a needle is inserted into the breast. A piece of tissue is extracted.
  • Participants who have chemotherapy may have blood taken after treatment/before surgery. Tissue may also be collected.
  • Participants will complete a questionnaire. It will ask about their social and economic background. It will ask about their family history of cancer. It will also ask about access to diagnosis and treatment of breast cancer.
  • Participants may be followed for up to 5 years.
Read the detailed description

The primary objective of this study is to characterize the distribution of molecular profiles in Latin American women with AJCC 7 clinical stage II or III breast cancer. The molecular profiles will be correlated with epidemiological, histological, and clinical characteristics, including pathologic response to standard neoadjuvant chemotherapy. Moreover, this study intends to define a molecular signature that will predict response to neoadjuvant therapy in breast cancer. This is a prospective cohort study in which no investigational drugs will be administered to participants. The study will be conducted at participating institutions in Argentina, Brazil, Chile, Mexico, and Uruguay.
