简要总结
This study is a multi-center BCCA study that evaluates the impact of the Oncotype DX® assay on the decision making of the treating physician and the patient. The Oncotype DX® assay is a commercially available diagnostic test that aids in a physician's treatment recommendation to a breast cancer patient. The study also has a pharmacoeconomic component.
详细描述
This study is a multi-center BCCA study that evaluates the impact of the Oncotype DX® assay on the decision making of the treating physician and the patient. The study also has a pharmacoeconomic component. All eligible patients in which either physician and/or patient determine that results from the 21 gene recurrence score could provide additional information useful in the decision making process regarding adjuvant chemotherapy or not will be asked by the participating physicians to participate in the study. If interested, the patient will consent to the study. The physician will complete a baseline questionnaire to document recommended adjuvant systemic therapies (pre-Oncotype DX®). The Oncotype DX® assay will be ordered after receipt of the Physician and Patient Registration and assignment of patient study number. The physician will discuss the results of the Oncotype DX® assay with the patient once the result is available and upon receipt of the pre-test questionnaire. The physician will complete a follow-up questionnaire (to document recommended adjuvant systemic therapies post Oncotype DX®) after the result of the Oncotype DX® assay is known.

- •Pathological involvement (microscopic) of 1-3 lymph nodes. No minimum number of total lymph nodes need be resected. Extra-nodal extension of nodal deposit is allowed.
- •Her2Neu negative by IHC (0 or 1+) or FISH by current ASCO/CAP guidelines
- •Patient's tumor must undergo central review at GHI and there must be adequate material for the Oncotype DX® assay.
- •Patient's tumor must contain estrogen receptors (ER+).
- •Patient must be between the ages (inclusive) of 18-
- •Patient must be able to give informed consent
- •Patient has adequate performance status (PS ECOG 0,1 or Karnofsky ≥70) and be a medically fit candidate for treatment of their cancer with systemic chemotherapy in addition to hormonal therapy with no contra-indications to either systemic therapy maneuvers
排除标准
- •Patients have ER negative tumors (ER-) by local or central BCCA assessment
- •Patients have HER2 positive tumors by local or central BCCA assessment
- •Patients have four or more lymph node positive disease.
- •Lymph node involvement by isolated tumor cells or cells by IHC only (less than 200 cells and/or ≤0.2 mm)
- •Patients have known metastatic breast cancer.
- •Patients are unable to give consent or understand written language.
- •Patients with poor performance status (ECOG 2-4) in whom consideration of adjuvant chemotherapy or adjuvant hormonal therapy would be contraindicated.
- •Pregnant women in whom consideration of adjuvant chemotherapy or adjuvant hormonal therapy would be contraindicated.
- •Patients with tumors that on GHI central pathological review appears inadequate for the Oncotype DX® assay.
