Study Evaluating DNA Double-strand Breaks (DSBs) REpair Factors (POLQ, Shieldin Complex and 53BP1) Expression as Biomarker of PARP Inhibitor Resistance in Patients With Deleterious Germline Mutation in BRCA 1/2 and HER2-negative, Metastatic or Locally Advanced Breast Cancer.
The purpose of this study is to assess whether expression of not only POLQ/Polθ, but also Shieldin complex and/or 53BP1 are correlated with primary and/or acquired resistance to PARPi (Poly(ADP-Ribose) Polymerases inhibitors) in a sub-population of locally advanced or metastatic breast cancer patients and vary regarding type and location of …
Abemaciclib Dose Escalation to Maintain Intensity (ADE-MI)
This is a post-marketing single arm, phase IV trial in which patients with high-risk early-stage HR+HER2- breast cancer will receive adjuvant abemaciclib in combination with endocrine therapy (ET) After study intervention, participants will remain on combination abemaciclib + ET at the discretion of their treating providers
A Randomized Trial of Chemotherapy in Surgical Patients With Infiltrating Ductal Carcinoma of Breast
The overarching purpose of this study is to determine if the mainstay chemotherapeutic regimens represented by several genotoxic agents including but not limited to Cyclophosphamide, Doxorubicin, Epirubicin, Fluorouracil and Methotrexate (CDEFM), in the format of either a single agent or combinations are safe, tolerable, and effective in the treatment of …
Improving Response to Chemotherapy by Adding Physical Exercise in the Neoadjuvant Setting of Breast Cancer Patients
One of the recommended treatments for breast cancer is neoadjuvant chemotherapy (NCT), however, only 20% of the patients subject to this therapy present pathologic complete response (pCR). If exercise-induced tumour size reductions observed in preclinical studies translates to humans, physical training could emerge as a way of increasing rates of …
TAD in Primary Breast Cancer With Initially ≥ 3 Suspicious Lymph Nodes
Due to high pathological complete remission (pCR) rates in both breast and lymph nodes (ypT0/Tis, ypN0) following neoadjuvant systemic therapy (NST) in many patients with initially clinically node-positive (cN+) breast cancer, the standard treatment of the axilla has changed from axillary lymph node dissection (ALND), which is associated with high …
Single Pre-Operative Radiation Therapy - With Delayed or No Surgery (SPORT-DNS)
Eligible women will receive neoadjuvant single fraction radiotherapy followed by surgery performed after one year
A Formative Evaluation For Improving Breast Cancer Hormone Receptor Testing in Tanzania
The purpose of this study is to learn more about the challenges with breast cancer diagnosis in Tanzania and the support available to improve this process.
[18F] F-GLN by PET/CT in Breast Cancer
Patients with known or suspected primary or metastatic breast cancer with one lesion that is 1.0 cm in diameter or greater may be eligible for this study. Patients may participate in this study if they are at least 18 years of age. Up to 40 evaluable subjects will participate in …
Trial Of PreoperAtive Radiation (TOPAz): A Randomized Trial Comparing Hypofractionated Versus Conventionally Fractionated Preoperative Radiation Followed by Mastectomy With Immediate Autologous Breast Reconstruction With Integrated Nanomechanical Biomarker Evaluation
To compare the outcomes of and responses to 2 different radiation therapy schedules (the standard radiation amount and number of doses versus less radiation and fewer doses) that are being given before having breast cancer surgery (cancer removal and reconstruction).
Converting HR+ Breast Cancer Into an Individualized Vaccine
Newly diagnosed post-menopausal women with clinical stage II-III, HR+HER2- breast cancer are eligible to a randomized trial, concurrently open at five US academic institutions. Patients receiving 4 months of standard neoadjuvant hormonal therapy with letrozole are randomly assigned to one of 4 arms of a trial testing focal hypo-fractionated RT …
