A Blended e-Health Intervention to Improve Fear of Progression in Women With Gynecologic or Breast Cancer

This clinical trial studies whether an intervention supported by technology (blended e-health intervention) works to improve fear of progression (FOP) in women with gynecologic or breast cancer. FOP is the fear patients experience from the possibility that their cancer could grow, spread, or get worse. Managing FOP is a leading unmet concern of cancer patients. High levels of FOP are associated with distress, depression, and increased health care costs, despite this, access to resources to address FOP remain limited. The blended e-health intervention in this trial offers remote group sessions along with online sessions to help patients access the information. Session content incorporates values-based goal setting and skills practices to manage unhelpful beliefs about worry and promote helpful coping behaviors. The sessions may help patients recognize unhelpful thoughts and behaviors which reinforce worry. A blended e-health intervention may be an effective way to improve FOP in women with gynecologic or breast cancer.

Testing Whether Hormone Therapy With Ribociclib is as Effective as Chemotherapy Followed by Hormone Therapy With Ribociclib for the Treatment of High Anatomic Stage Breast Cancer With Low Recurrence Risk, The RxFINE-Low Trial

This phase III trial compares standard of care hormone therapy plus ribociclib to chemotherapy followed by hormone therapy plus ribociclib for the treatment of patients with high anatomic stage breast cancer with low risk of the cancer returning (low risk recurrence). Ribociclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Hormone therapy, with letrozole, anastrozole or exemestane, lowers the amount of estrogen made by the body. This may help stop the growth of tumor cells that need estrogen to grow. Chemotherapy drugs 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. Hormone therapy plus ribociclib may work as well as chemotherapy followed by hormone therapy plus ribociclib for the treatment of high anatomic stage breast cancer with low recurrence risk.

A Vaccine (STEMVAC) for Improving Survival in Patients With Triple-Negative Breast Cancer and Moderate or Extensive Residual Cancer Burden

This phase II trial evaluates whether a multi-antigen vaccine called STEMVAC improves disease-free survival after surgery in patients with triple-negative breast cancer (TNBC) and moderate or extensive residual cancer burden. TNBC has an aggressive clinical course and poorer disease-free survival compared to other subtypes. While patients who have no remaining tumor in the breast or lymph nodes after surgery have excellent long-term outcomes, patients with moderate or extensive residual cancer burden remain at high risk for early disease return and poorer prognosis. STEMVAC is designed to target proteins that tumor cells use when they become more aggressive and start to spread, and it is believed to work by boosting the immune system to recognize and destroy the invader tumor cells that are causing the disease. Giving STEMVAC after surgery may improve disease-free survival rates in TNBC patients with moderate or extensive residual cancer burden.

Adding an Immunotherapy Drug, MEDI4736 (Durvalumab), to the Usual Chemotherapy Treatment (Paclitaxel, Cyclophosphamide, and Doxorubicin) for Stage II-III Breast Cancer

This phase III trial compares the addition of an immunotherapy drug (durvalumab) to usual chemotherapy versus usual chemotherapy alone in treating patients with MammaPrint High 2 Risk (MP2) stage II-III hormone receptor positive, HER2 negative breast cancer. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as paclitaxel, doxorubicin, and 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. There is some evidence from previous clinical trials that people who have a MammaPrint High 2 Risk result may be more likely to respond to chemotherapy and immunotherapy. Adding durvalumab to usual chemotherapy may be able to prevent the cancer from returning for patients with MP2 stage II-III hormone receptor positive, HER2 negative breast cancer.

Identifying Decision Making Needs for Older Adult Women With Stage I-III Breast Cancer Considering Neoadjuvant or Adjuvant Chemotherapy

This study collects information and identifies decision making needs for older adult women with stage I-III breast cancer considering neoadjuvant and adjuvant chemotherapy. Using this information, a decision support tool is then developed to provide patients and physicians with tailored information regarding the risks and benefits of chemotherapy and values clarification to support high-quality, shared decision. Subsequently, the decision support tool will be tested amongst older patients with early-stage breast cancer and health care providers navigating the decision process around chemotherapy, and further refined through an iterative process.

US/PA/E Imaging for Early Identification of Tumor Response in Patients With Stage II-III Triple Negative Breast Cancer Receiving Neoadjuvant Immunotherapy and Chemotherapy

This clinical trial studies how well ultrasound/photoacoustic/elasticity (US/PA/E) imaging works for early identification of tumor response in patients with stage II-III triple-negative breast cancer receiving immunotherapy and chemotherapy before surgery (neoadjuvant). US imaging uses high-energy sound waves to look at tissues and organs inside the body. The sound waves make echoes that form pictures of the tissues and organs on a computer screen. PA imaging delivers laser light into tissue which produces ultrasonic waves which are then converted into images. Elastography (i.e., elasticity \[E\]) imaging uses sound waves to send vibrations into a specific organ and measures how fast those vibrations move. The vibrations move faster through areas of stiff tissue and a computer uses these measurements to make an image of those areas. Combined US/PA/E imaging using the Vevo F2 and Vevo LAZR-X20 devices may be safe and provide earlier information about tumor response to standard neoadjuvant immunotherapy and chemotherapy than current standard imaging.

Personalized Exercise Program for Survivors of Breast Cancer, STEPS-BC Trial

This clinical trial studies whether a healthy living intervention (HLI), with or without a physical activity intervention (PAI), helps maintain the ability to exercise, heart health, and quality of life in breast cancer patients who are scheduled to receive chemotherapy treatment. Early detection and enhanced therapies for breast cancer have improved 5-year cancer-related survival rates. Unfortunately, many breast cancer survivors are at high risk for long-term exercise intolerance, decreased heart health, and lower quality of life following chemotherapy. Currently, there are no effective therapies to help patients maintain these areas throughout chemotherapy. The HLI in this study includes virtual health education classes, which provide useful information on topics like proper nutrition, managing stress, and sleep practices. This may help patients understand the importance of living a healthy lifestyle during chemotherapy. The PAI in this study consists of virtual exercise sessions personalized to the needs of the patient, which may make it easier for patients to stay active during chemotherapy. HLI with PAI may be a more effective way to help maintain ability to exercise, heart health, and quality of life in breast cancer patients who are scheduled to receive chemotherapy treatment.

Treatment Effects on Development of Chemotherapy-Induced Peripheral Neuropathy in Patients With Cancer

This trial studies treatment effects on development of chemotherapy-induced peripheral neuropathy in patients with cancer. Treatments for cancer can cause a problem to the nervous system (called peripheral neuropathy) that can lead to tingling or less feeling in hands and feet. Studying certain risk factors, such as age, gender, pre-existing conditions, and the type of treatment for cancer may help doctors estimate how likely patients are to develop the nerve disorder.

ShortStop-HER2: 12 Months vs. 6 Months of HER2-targeted Medications for People With HER2+ Breast Cancer Who Had a Pathologic Complete Response After Chemotherapy Plus Trastuzumab

This phase III trial compares 6 months of human epidermal growth factor receptor 2 (HER2)-targeted therapy to 12 months of HER2-targeted therapy for the treatment of HER2-positive (+) breast cancer in patients that had a pathologic complete response (pCR) after preoperative (neoadjuvant) chemotherapy with trastuzumab. Trastuzumab and pertuzumab are monoclonal antibodies and forms of targeted therapy that attach to a receptor protein called HER2. HER2 is found on some cancer cells. When trastuzumab or pertuzumab attach to HER2, the signals that tell the cells to grow are blocked and the tumor cell may be marked for destruction by the body's immune system. Giving 6 months of HER2-targeted therapy may work better than giving 12 months for the treatment of HER2+ breast cancer in patients that had a pCR after neoadjuvant chemotherapy with trastuzumab.

Evaluation of Alternative Site Goserelin Acetate Injection for Ovarian Function Suppression (OFS) in Local and Locally Advanced Premenopausal Hormone Receptor Positive Breast Cancer Patients

This phase II trial determines if giving goserelin acetate injections in the upper gluteal region is as effective for ovarian function suppression (OFS) as giving injections in the abdomen for ovarian function suppression (OFS) in premenopausal patients with hormone receptor positive breast cancer that has not spread to other parts of the body (localized) or that has spread to nearby tissue or lymph nodes (locally advanced). Goserelin acetate is a drug used to treat prostate cancer, relieve the symptoms of advanced breast cancer, and treat problems with the endometrium (lining of the uterus). Goserelin acetate initially causes the pituitary gland to make more luteinizing hormone (LH) and follicle-stimulating hormone (FSH), temporarily increasing testosterone levels in men and estrogen levels in women. With continued use, goserelin acetate lowers the amount of LH and FSH the pituitary gland releases, leading to a drop in testosterone levels in men and estrogen levels in women. Goserelin acetate may stop the growth of cancer cells that need testosterone or estrogen to grow. It is a type of hormone therapy called a luteinizing hormone-releasing hormone (LHRH) agonist. Giving goserelin acetate injections in the upper gluteal region may be as effective for OFS as giving injections in the abdomen for OFS in premenopausal patients with localized or locally advanced hormone receptor positive breast cancer.

Additional Support Program Via Text Messaging and Telephone-Based Counseling for Breast Cancer Patients Receiving Hormonal Therapy

This phase III trial compares an additional support program (text message reminders and/or telephone-based counseling) with usual care in making sure breast cancer patients take their endocrine therapy medication as prescribed (medication adherence). Medication adherence is how well patients take the medication as prescribed by their doctors, and good medical adherence is when patients take medications correctly. Poor medication adherence has been shown to be a serious barrier to effective treatment for hormone receptor positive breast cancer patients. Adding text message reminders and/or telephone-based counseling to usual care may increase the number of days that patients take their endocrine therapy medication as prescribed.

Ph2 Study for Optimization of Adjunct Systemic Therapy in HER2+ Patients, MolecularPCR Trial

This phase II trial tests reduced post surgery (adjuvant) therapy for patients with early breast cancer who have confirmed that the disease has responded completely (pathologic complete response) after pre surgical treatment (neoadjuvant) therapy and do not have any tumor genetic material (molecular residual disease) circulating in their blood. Standard of care treatment after surgery consists of 1 year of pembrolizumab for patients with triple negative breast cancer or trastuzumab with or without pertuzumab to complete 1 year of treatment. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Pertuzumab and trastuzumab are monoclonal antibodies and forms of targeted therapy that attach to a receptor protein called HER2. HER2 is found on some cancer cells. When pertuzumab or trastuzumab attach to HER2, the signals that tell the cells to grow are blocked and the tumor cell may be marked for destruction by the body's immune system. Lowering the total amount of cancer therapy after breast surgery, may continue to keep the great tumor response to treatment, and may help lower the amount of side effects patients have.

An Optimized Ultrasound Twinkling Marker for the Imaging of Lymph Nodes in Patients With Clinically Node-Positive Breast Cancer, The UTMOST2 Trial

This phase I trial studies the performance, including ultrasound visibility, of an optimized ultrasound twinkling marker in imaging lymph nodes in patients with clinically node-positive breast cancer. In patients with biopsy-proven breast cancer, biopsy markers are used to identify the sites of cancer involvement in both the breasts and lymph nodes. These biopsy markers are critical for guiding surgical management many months after the marker is placed. For breast radiologists and breast surgeons, there is a need for simple, consistent visibility of biopsy markers by ultrasound, particularly several months after marker placement. Ultrasound is the imaging method of choice, particularly for lymph nodes in the armpit (axilla). Ultrasound is non-ionizing and is more comfortable for patients compared to mammography. However, ultrasound visibility of these markers is challenging and inconsistent, with ultrasound failing to detect the marker approximately 25% of the time. The Mayo-designed investigational biopsy marker takes advantage of an ultrasound phenomenon called twinkling artifact. The Mayo-designed optimized ultrasound twinkling marker may work better than standard biopsy clip marker in imaging lymph nodes in patients with clinically node-positive breast cancer.

CompassHER2-pCR: Decreasing Chemotherapy for Breast Cancer Patients After Pre-surgery Chemo and Targeted Therapy

This trial studies how well paclitaxel, trastuzumab, and pertuzumab work in eliminating further chemotherapy after surgery in patients with HER2-positive stage II-IIIa breast cancer who have no cancer remaining at surgery (either in the breast or underarm lymph nodes) after pre-operative chemotherapy and HER2-targeted therapy. Drugs used in chemotherapy, such as paclitaxel, 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. Trastuzumab and pertuzumab are both a form of "targeted therapy" because they work by attaching themselves to specific molecules (receptors) on the surface of tumor cells, known as HER2 receptors. When these drugs attach to HER2 receptors, the signals that tell the cells to grow are blocked and the tumor cell may be marked for destruction by the body's immune system. Giving paclitaxel, trastuzumab, and pertuzumab may enable fewer chemotherapy drugs to be given without compromising patient outcomes compared to the usual treatment.

Testing the Role of FDG-PET/CT to Predict Response to Therapy Prior to Surgery for HER2-positive Breast Cancer, The DIRECT Trial

This phase II trial tests how well an imaging procedure called fludeoxyglucose F-18 (FDG) positron emission tomography/computed tomography (PET/CT) works in predicting response to standard of care chemotherapy prior to surgery in patients with HER2-positive stage IIa-IIIc breast cancer. FDG is a radioactive tracer that is given in a vein before PET/CT imaging and helps to identify areas of active cancer. PET and CT are imaging techniques that make detailed, computerized pictures of areas inside the body. The use of FDG-PET/CT may help doctors better decide if a patient needs more or less treatment before surgery in order to get the best response. This study evaluates whether FDG-PET/CT is useful in predicting a patient's response to standard of care chemotherapy.

Breast Cancer, Reasoning, and Activity Intervention

This phase II trial tests whether an exercise intervention works to improve cognitive function in breast cancer survivors. Many breast cancer survivors report cancer-related cognitive impairment, which this has recently become a priority in clinical research due to its dramatic impact on daily functioning, quality of life, and long-term health. Aerobic exercise has the potential to improve cognitive function and brain health in older adults and is recommended as a safe, tolerable, and accessible complementary therapy for breast cancer survivors. This study aims to understand the effects of physical activity compared with health education on memory, attention, and brain health in women with breast cancer. Study findings may help researchers design more programs that can improve memory, attention, and brain health in other women with breast cancer.

Hypofractionated Radiotherapy Before or After Breast Surgery for Treatment of Patients With Non-Metastatic Breast Cancer

This phase II trial studies how well hypofractionated radiotherapy before (preoperative) or after (postoperative) breast surgery works in treating patients with different types of non-metastatic (has not spread from original tumor site) breast cancer and to determine the outcomes and side effects of this treatment. Radiation therapy is considered an integral part of breast conserving therapy. Hypofractionated radiation therapy is a radiation treatment in which the total dose of radiation is divided into large doses and treatments are given less than once a day. This has been shown to be an effective treatment for breast cancer while reducing treatment time and decreasing side effects. Preoperative radiotherapy alone or concurrently with chemotherapy has also been tested with excellent results and with minimal toxicity. Preoperative radiation of the intact tumor with a hypofractionated regimen can potentially decrease toxicity by allowing the delivery of treatment to intact breast tissue. The potential advantages of preoperative radiation therapy include the delivery of radiation in the intact breast when radiation can be more effective as more oxygen can be available in the tissue. Furthermore, complications and cosmetic results are expected to be lower in pre-operative radiotherapy before surgery, as there have been no changes in blood supply to the breast. This lends to the possibility of using lower doses of radiotherapy to patients, and potentially better cancer associated clinical outcomes for our breast cancer patients. Undergoing hypofractionated radiation therapy before or after breast surgery may be safe and effective in treating patients with different types of non-metastatic breast cancer.
