RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors predict how well patients will respond to treatment. It may also help the study of cancer in the future.
PURPOSE: This laboratory study is looking at blood samples from patients receiving trastuzumab and/or chemotherapy for HER2-positive solid tumors to assess T-cell response.
- Assess T-cell activation in blood samples of patients receiving trastuzumab (Herceptin®) and/or chemotherapy for HER2-positive solid tumors.
OUTLINE: Blood samples are collected from patients at baseline and on days 21, 42, and 84 of trastuzumab (Herceptin®)/chemotherapy. Patients may be contacted 3-6 months after completion of trastuzumab/chemotherapy to donate another blood specimen.
Blood samples are examined for T-cell proliferation and intracellular cytokine production. CD8 T-cell response, HER2/neu-specific antibody titers, and skin hypersensitivity test responses are also measured.
PROJECTED ACCRUAL: A total of 20 patients will be accrued for this study.
Primary Purpose: Treatment
trastuzumab, chemotherapy, immunologic technique, laboratory biomarker analysis

Chemotherapy plus 1-year trastuzumab is the standard adjuvant treatment for HER2-positive breast cancer. The efficacy of less extended trastuzumab exposure is under investigation. The Short-HER study ...
Effect of Adjuvant Trastuzumab for a Duration of 9 Weeks vs 1 Year With Concomitant Chemotherapy for Early Human Epidermal Growth Factor Receptor 2-Positive Breast Cancer: The SOLD Randomized Clinical Trial.
Trastuzumab plus chemotherapy is the standard adjuvant treatment for patients with human epidermal growth factor receptor 2 (HER2)-positive early breast cancer. While the standard duration of trastuzu...
Trastuzumab (H) with chemotherapy benefits patients with HER2+ breast cancer (BC); however, we lack head-to-head pairwise assessment of survival or cardiotoxicity for specific combinations. We sought ...
Combined anthracycline-trastuzumab chemotherapy has been associated with LV dysfunction. We aimed to assess early changes in left ventricular (LV) and right ventricular (RV) mechanics associated with ...
Prediction of postoperative disease-free survival and brain metastasis for HER2-positive breast cancer patients treated with neoadjuvant chemotherapy plus trastuzumab using a machine learning algorithm.
This study aimed to develop mathematical tools to predict the likelihood of recurrence after neoadjuvant chemotherapy (NAC) plus trastuzumab in patients with human epidermal growth factor receptor 2 (...
A humanized monoclonal antibody against the ERBB-2 RECEPTOR (HER2). As an ANTINEOPLASTIC AGENT, it is used to treat BREAST CANCER where HER2 is overexpressed.
Drug treatment designed to further diminish the disease toward complete remission following INDUCTION CHEMOTHERAPY. It helps to consolidate the gains during induction chemotherapy and may be followed by MAINTENANCE CHEMOTHERAPY.
Proteins, protein complexes, or glycoproteins secreted by suppressor T-cells that inhibit either subsequent T-cells, B-cells, or other immunologic phenomena. Some of these factors have both histocompatibility (I-J) and antigen-specific domains which may be linked by disulfide bridges. They can be elicited by haptens or other antigens and may be mass-produced by hybridomas or monoclones in the laboratory.
The analysis of an activity, procedure, method, technique, or business to determine what must be accomplished and how the necessary operations may best be accomplished.
Treatment designed to help prevent a relapse of a disease following the successful primary treatments (INDUCTION CHEMOTHERAPY and CONSOLIDATION CHEMOTHERAPY) with a long-term low-dose drug therapy.

Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
