A Phase II Study Evaluating the Efficacy and Safety of Inavolisib Plus Ribociclib Plus Fulvestrant Versus Placebo Plus Ribociclib Plus Fulvestrant in Participants With Advanced Breast Cancer

A study to evaluate the efficacy and safety of triplet combination of inavolisib plus ribociclib and fulvestrant versus placebo plus ribociclib and fulvestrant in the first-line setting in participants with endocrine-therapy-resistant hormone receptor (HR)-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer (ABC).

To Assess the Correlation of High-resolution Specimen PET-CT Imaging, Using the XEOS AURA 10 PET-CT, With the Histopathology Results and Long-term Outcome of Patients Undergoing Resective Cancer Surgery.

This registry study aims to evaluate the effectiveness and clinical impact of specimen PET-CT imaging by analyzing the correlation between specimen PET-CT images, intraoperative interpretations, and histopathological findings. Additionally, it assesses how these imaging insights influence clinical decision-making and long-term patient outcomes. Through this comprehensive analysis in a real-world setting, the study seeks to generate valuable insights that can enhance specimen evaluation processes and ultimately improve patient care.

Atezolizumab Plus Tivozanib in Immunologically Cold Tumor Types

Checkpoint inhibitor therapy represents a significant advance in cancer care. The interaction between PD-1 and PD-L1 induces immune tolerance, and the inhibition of this interaction is an effective treatment strategy for numerous malignancies. Despite its demonstrated potential, immunotherapy is not currently thought to be an effective intervention in the treatment of several immunologically "cold" tumors such as prostate cancer, biliary tract cancers, soft tissue sarcomas, well-differentiated neuroendocrine tumors, microsatellite stable colorectal cancer, pancreatic cancer, and non-triple negative breast cancer. Vascular endothelial growth factor (VEGF) is thought to play a key role in modulating the anti-tumor immune response. Vascular endothelial growth factor (VEGF) is secreted by tumors and leads to endothelial cell proliferation, vascular permeability, and vasodilation. This in turn leads to the development of an abnormal vasculature with excessive permeability and poor blood flow, limiting immune surveillance. In addition, VEGF inhibits dendritic cell differentiation, limiting the presentation of tumor antigens to CD4 and CD8 T cells. Vascular endothelial growth factor (VEGF). VEGF tyrosine kinase inhibitors (TKIs) VEGF-TKIs are currently utilized in the treatment of a variety of malignancies and are widely utilized in combination with checkpoint blockade in the treatment of clear cell kidney cancer. Through the inhibition of VEGF, it may be possible to potentiate the effect of immune checkpoint blockade even in tumors which have traditionally been thought to be unresponsive to immunotherapy. This study aims to evaluate the combination of the immune checkpoint inhibitor atezolizumab and the VEGF-TKI tivozanib in a variety of tumors which have a low response rate to checkpoint inhibitor therapy alone.

A Cohort Study of Combined Cryoablation and Thermal Ablation for Non-surgical Treatment of Breast Cancer Patients

Although surgical resection is the gold standard for early breast cancer treatment, some patients cannot tolerate surgery due to medical conditions or refuse surgical treatment for cosmetic reasons. In recent years, the rapid development of ablation technology has provided new directions for breast cancer patients who are not suitable for surgical treatment. Ablation uses high or low temperatures to deactivate lesions or tissues, which are gradually absorbed by the body, achieving local treatment purposes. Its safety and efficacy have been preliminarily confirmed. As an advanced minimally invasive medical device independently developed in China, the combined cryo-thermal ablation system treats tumors using a combined mode of deep cryogenic freezing and high-intensity heating. It has been approved for ablation treatment of various solid tumors including lung cancer, pancreatic cancer, kidney cancer, prostate cancer, breast cancer, bone and soft tissue sarcomas. This project proposes a prospective cohort design, based on the breast disease cohort database of Peking University People's Hospital Breast Center. It will enroll patients pathologically diagnosed with breast cancer, determined unsuitable for surgical treatment, and have received combined cryo-thermal ablation. The registered data will be used to evaluate the effectiveness and safety of percutaneous ultrasound-guided cryo-thermal composite ablation in this population.

Collection of CSF Samples From Participants With Metastatic Triple Negative Breast Cancer (TNBC) and HER2+ Breast Cancer With no Prior History Nor Active Radiographically Detectable Brain Metastases

Background: Breast cancer is the most common cancer among women. It can often spread to the liver, lungs, bones, or brain. Breast cancer that spreads to the brain is often fatal. Researchers want to know if tumor DNA found in spinal fluid, blood, or tumor tissue can help predict when the cancer will spread to the brain. They want to collect these fluid and tissue samples for research. Objective: To collect spinal fluid and other samples from people with breast cancer that has spread to other parts of the body. Eligibility: People aged 18 years and older with HER2-positive or triple negative breast cancer. The cancer must have spread to other parts of the body but not to the brain. Design: Participants will be screened. They will have blood tests to assess kidney function. They will have an imaging scan of the brain. Participants will come to the NIH clinic to have their samples collected: * Spinal fluid. A thin needle will be inserted into the lower back to draw out a sample of fluid from the space around the spinal cord. A physical exam and blood tests will be done to make sure it is safe for participants to have this procedure. * Blood. * Saliva or cheek swabs. They will rub a cotton swab inside of their mouth. * Tumor samples. If participants have had samples of tumor tissue (biopsies) collected in the past, leftover tissue may be used for this study. Participants will be contacted for follow-up every 6 months for 3 years. They may return once a year to provide further samples....

Distance-Based Exercise to Preserve Function and Prevent Disability

This clinical trial studies whether an exercise program can be successfully delivered to patients receiving treatment for cancer through virtual sessions and allow patients to exercise in their own home. Treatments for cancer can cause side effects such as fatigue and loss of strength. These side effects can make it difficult to work, take care of family, and do other things the patient wants to do. Preliminary research shows that exercise can help prevent some of these side effects, but it can be more difficult to start an exercise program when a patient is receiving cancer treatment. The exercise program in this study is delivered through telehealth (TH) video calls. The TH sessions are delivered by trained staff that supervise resistance exercises. The trained staff also provide guidance to the patient on completing unsupervised aerobic sessions on their own. This may be a successful way to deliver an exercise program and make it easier for cancer patients to exercise in their own home during treatment.

A Study of an Alternative Treatment Approach (Preoperative Radiotherapy, Then Mastectomy, Then Immediate Reconstruction Surgery) in People With T4 Breast Cancer

The purpose of this study to test an alternative treatment approach that involves giving participants radiotherapy before their mastectomy (preoperative radiotherapy) and performing immediate reconstruction surgery at the time of mastectomy. The immediate reconstruction surgery is called an immediate autologous reconstruction (IR) and is different than the standard reconstruction surgery people with T4 breast cancer have. IR is a surgical procedure where immediately following your mastectomy, the surgeon takes tissue from another part of your body and uses it to re-create your breast. The standard reconstruction surgery occurs later and can be done with an implant or tissue from your body. The main purpose of this study to find out if the alternative treatment approach shown above is feasible. The study will see how safe this alternative treatment approach is compared with the standard treatment approach.
