About

This is a pilot study to gather preliminary data on the baseline immunologic status of patients with HER-2(+) breast cancer and to establish an immune monitoring laboratory for future clinical trial.

Full description

This is a pilot study to gather preliminary data on the baseline immunologic status of patients with HER-2(+) breast cancer and to establish an immune monitoring laboratory for future clinical trial. We will ask up to 10 patients with HER-2(+) breast cancer in stable condition and in reasonable health to participate in this study. The study will establish an immune monitoring for correlative studies done in patients with HER-2(+) breast cancer. The immunologic tests that will be done are ELISpot, lymphocyte proliferation, intracellular cytokine staining, lymphocyte immunophenotyping, and ELISA.

Enrollment: 4 patients

Sex: Female

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Age >= 18 years of age

• Histologically documented breast cancer (hormone receptor (ER/PR) status may be either positive or negative) with or without metastatic disease.

• HER-2(+) as determined by one of the following measurements. NOTE: HER-2(+) assessment may have been on initial diagnosis and need not be repeated for metastatic lesions

  • Immunohistochemistry (IHC) 3+, or
  • FISH + (HER-2 gene signal to centromere 17 signal >2)

• Patients must not have active or unresolved infection.

• No cold or flu sympton at time of donation

• No prior myocardial infarction or active cardiac disease (e.g. congestive heart failure, clinically significant cardiac valvular disease or arrhythmia requiring medications, angina pectoris, uncontrolled hypertension, clinically significant pericardial effusion)

• All patients must give signed written informed consent.
