Genetic Testing in Predicting Tumor Response in Patients With Stage I-III HER2 Negative Invasive Breast Cancer
Bu çalışma, Evre I-III HER2 negatif invaziv meme kanseri hastalarında genetik testin tümörün tedaviye yanıtını öngörmedeki değerini araştırıyor. En az 1 cm tümörü olan hastalar dahil edilmiştir. Faz 2 aşamasında yürütülmüş; şu an katılımcı almamakta ancak devam etmektedir (active, not recruiting).

Inclusion Criteria: * The patient can undergo biopsy or surgery of a primary tumor site for suspected or proven invasive breast cancer of clinical stage I to III; stage IV patients will be allowed and included in the feasibility assessment, but will not be included in outcomes analysis for secondary objectives * The clinical or radiologic primary tumor size is at least 1 cm diameter Exclusion Criteria: * The patient has proven HER2-positive breast cancer, defined as a pathology report of amplification of the gene or 3+ score for immunohistochemical staining * The patient has received prior systemic therapy or radiation therapy for breast cancer * The patient has a prior history of invasive or metastatic cancer within 5 years of diagnosis of breast cancer, excluding squamous cell or basal cell carcinoma of the skin * The patient had prior excisional biopsy of the primary invasive breast cancer * There is hematoma or biopsy site changes that obscure the primary tumor * Patients deemed medically ineligible for any adjuvant or neoadjuvant therapy. Patients with ER-positive (+) tumors deemed medically eligible for hormonal therapy, but not chemotherapy will be considered eligible for this protocol. Patients with ER-negative (-) tumors who are not candidates for adjuvant anthracycline based chemotherapy will be considered ineligible for this protocol. Patients who undergo biopsy and are later found to be ineligible for adjuvant therapy will be assessed for the primary objective, but will be excluded from the secondary objectives
