Hormone Therapy With or Without Combination Chemotherapy in Treating Women Who Have Undergone Surgery for Node-Negative Breast Cancer (The TAILORx Trial)

This randomized phase III trial studies the best individual therapy for women who have node-negative, estrogen-receptor positive breast cancer by using a special test (Oncotype DX), and whether hormone therapy alone or hormone therapy together with combination chemotherapy is better for women who have an Oncotype DX recurrence score of 11-25. Estrogen can cause the growth of breast cancer cells. Hormone therapy may fight breast cancer by blocking the use of estrogen by the tumor cells or by lowering the amount of estrogen the body makes. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving hormone therapy together with more than one chemotherapy drug (combination chemotherapy) has been shown to reduce the chance of breast cancer recurrence, but the benefit of adding chemotherapy to hormone therapy for women with node-negative, estrogen-receptor positive breast cancer is small. New tests may provide information about which patients are more likely to benefit from chemotherapy.

Hypofractionated Radiation Therapy or Standard Radiation Therapy in Treating Patients With Ductal Breast Carcinoma In Situ or Early Invasive Breast Cancer

This randomized phase II trial studies how well hypofractionated radiation therapy (RT) works compared to standard RT in treating patients with ductal breast carcinoma in situ (DCIS) or early invasive breast cancer. Radiation therapy (RT) uses high energy x-rays to kill tumor cells. Giving higher doses of RT over a shorter period of time may kill more tumor cells and have fewer side effects. It is not yet known if hypofractionated RT is more effective than standard RT in treating breast cancer.

Multicenter Trial for Eliminating Breast Cancer Surgery or Radiotherapy in Exceptional Responders to Neoadjuvant Systemic Therapy

This clinical trial studies eliminating surgery and/or radiation therapy in treating breast cancer patients. In HER2 positive and triple negative breast cancers, after systemic therapy, when image-guided biopsy shows no residual cancer, patients then receive standard breast radiotherapy with no surgery. In ER positive/HER2 negative breast cancers, after endocrine therapy and ablative radiotherapy, when image-guided biopsy shows no residual cancer, patients then receive standard endocrine therapy with no surgery. For patients who have HER2 positive and triple negative breast cancers and standard surgery, after systemic therapy, breast radiotherapy is being eliminated when the pathology from surgery shows no residual cancer.

Hypofractionated vs. Conventional Regional Nodal Radiation Therapy for Patients With Invasive Breast Cancer

To compare how often cancer recurs (comes back) after 3 weeks of radiation compared to 5 weeks of radiation in patients who receive radiation therapy delivered to the lymph nodes near the breast. The side effects that can develop during or after radiation treatment, including how often arm swelling (edema) happens, will also be studied.

Radiation Therapy in Treating Patients With Stage 0-II Breast Cancer

This phase II trial studies the side effects and how well radiation therapy works in treating patients with stage 0-II breast cancer. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue.

The Role of Lifestyle Factors in Breast Cancer-Related Outcomes

This randomized clinical trial studies an integrative oncology (making changes in lifestyle and behavior) program in improving cancer-related outcomes in patients with stage II or III breast cancer undergoing radiation therapy. An integrative oncology program consisting of dietary recommendations, physical activity, stress management, social support, and control of environmental contaminants may modify cancer-related biological processes, influence long-term treatment results, and improve the quality of life of patients.

Electroacupuncture Therapy in Reducing Chronic Pain in Patients After Breast Cancer Treatment

This randomized phase II trial studies how well electroacupuncture therapy works in reducing chronic pain in patients following surgery for stage I-III breast cancer. Electroacupuncture therapy is a type of complementary integrative medicine in which pulses of weak electrical current are sent through very thin, solid, sterile, stainless steel needles into certain points in the skin. Electroacupuncture therapy may help to lower pain and other surgery-related symptoms.

Molecular Testing and Imaging in Improving Response in Patients With Stage I-III Triple-Negative Breast Cancer Receiving Chemotherapy MDACC Breast Moonshot Initiative

This clinical trial assesses whether a newly designed algorithm which looks at the genomic signature of each patient's tumor to predict their sensitivity to standard of care treatment verses being placed on a personally designed treatment trial can improve the responses in patients with newly diagnosed triple-negative breast cancer (TNBC). Testing the primary tumor biopsy for certain proteins and monitoring the lymphocyte infiltration into the tumors may help doctors determine the sub-type of TNBC, and direct treatments that may work well. It is not yet known whether assigning treatment based on the patient's tumor classification will improve how well the tumor responds.

Multi-epitope Folate Receptor Alpha Peptide Vaccine, GM-CSF, and Cyclophosphamide in Treating Patients With Triple Negative Breast Cancer

This randomized phase II trial studies how well multi-epitope folate receptor alpha peptide vaccine, sargramostim (GM-CSF), and cyclophosphamide work to prevent the recurrence of stage 1-3 triple negative breast cancer. Vaccines made from a person's white blood cells mixed with tumor proteins may help the body build an effective immune response to kill tumor cells. Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving multi-epitope folate receptor alpha peptide vaccine, sargramostim (GM-CSF), and cyclophosphamide may work well together to prevent cancer recurrence after surgery and other standard treatments for triple negative breast cancer.
