Participants will receive a single intravenous infusion of QL1209 or US-Perjeta® 420 mg on D1, followed by observation until Day 99 postdose for PK, safety and immunogenicity assessments.

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.

This is a Phase 3, open-label, randomized, clinical trial evaluating the efficacy and safety of gedatolisib and palbociclib plus endocrine therapy for the treatment of patients with locally advanced or metastatic HR+/HER2- advanced breast cancer.

Background: Genes are the instructions a person s body uses to function. Genome sequencing reads through all of a person s genes. Everyone has many gene variants, and most do not cause disease. Some gene variants called secondary findings may be important for a person s health even if they are not related to the reason why a person had genome sequencing done. Researchers want to learn more about what it means to have a secondary finding. Objectives: To learn about how gene variants may affect a person s health. To learn about how people understand their genetic test results. Eligibility: People with secondary findings from genetic testing done as part of a research study, clinical care, or other methods. Design: Participants may be asked to do an online survey and phone interview to ask what they think about their results, their healthcare, and if they talk with their family about the result. Eligible participants may be offered a visit to the NIH Clinical Center where they will be evaluated for health problems related to the secondary finding. DNA samples that were already collected may be studied. Participants may be asked to send in a second DNA sample (blood or saliva). These will be used to verify any findings. Participants who have a secondary finding can get genetic counseling.

Background: \- Some genes may be associated with a greater chance of side effects during cancer treatment. These genes may also make certain treatments less effective. Researchers want to collect blood or cheek swab samples from people having cancer treatment to study these genes. Objectives: \- To obtain a blood or cheek swab sample to study genetic differences that may affect cancer treatment. Eligibility: \- Individuals with cancer who are being treated at the National Cancer Institute. Design: * Participants will provide a blood sample for study. * Participants who have blood-based cancer, such as leukemia, will provide a cheek swab sample. * If the blood or cheek swab sample does not have enough genetic material for analysis, an additional sample may be collected.

This is a monocentric, low-risk interventional study designed to characterize established treatment-related dermatologic toxicity in patients receiving systemic anticancer therapies. The study will not modify or influence oncologic treatment decisions but will perform standardized instrumental and clinical dermatologic assessments during the course of routine cancer care.

This study will investigate whether the serratus posterior superior intercostal plane (SPSIP) block improves postoperative recovery after breast cancer surgery. Participants will be randomly assigned to one of two groups. One group will receive an ultrasound-guided SPSIP block, while the other group will undergo a similar procedure without active medication (sham procedure). Both groups will receive standard general anesthesia and postoperative pain management. Postoperative pain intensity, need for additional pain medication, nausea and vomiting, length of hospital stay, and persistent pain at 3 months after surgery will be assessed. Blood samples collected before surgery and at predetermined postoperative time points will be used to evaluate the body's inflammatory response to surgery and innate immune system activity. These assessments will include toll-like receptor 4 (TLR4), an immune-system marker, and selected inflammatory markers. The main question of this study is whether the SPSIP block, compared with the sham procedure, reduces the surgery-related inflammatory response and improves postoperative pain outcomes.

This prospective, national, multi-centre study will include patients with stage III triple-negative breast cancer (TNBC) who are planned to start with standard (neo)adjuvant systemic treatment. The study will gather clinico-pathological, treatment and follow-up information of participating patients through Dutch databases. Participating patients will be asked to complete cancer specific and more generic quality of life questionnaires at nine time points during and after their anticancer treatment in a mobile application. For all patients who have consented to additional blood collection, to assess the course of dynamic ctDNA during (neo)adjuvant chemotherapy and its relation with outcome, two tubes will be collected at four different time points.

The objective of this study is to evaluate the safety, tolerability, and efficacy of BL-M07D1 in patients with HER2 expressing advanced tumors.

The purpose of this study is to test the safety and effectiveness of an investigational drug combination (trastuzumab deruxtecan and durvalumab) to learn whether the intervention works in treating Human Epidermal growth factor Receptor-2 (HER2)-expressing inflammatory breast cancer.

This pilot study will evaluate the validity and feasibility of ambulatory cardiac monitoring to identify markers of cardiotoxicity in adults undergoing cancer treatment. Participants with breast cancer, hematologic malignancy, or multiple myeloma will receive usual care plus two wearable patch monitors: mobile cardiac telemetry using the BodyGuardian Mini Plus ambulatory ECG monitor and an investigational wearable cardiac monitor that records heart sounds. The study will assess arrhythmias detected by mobile cardiac telemetry and explore whether heart sounds are associated with echocardiographic findings and cardiac biomarkers. Participants will wear the devices during cancer treatment, with monitoring periods at baseline and possible repeat monitoring at 6-month and 12-month study visits.

The ARC Registry is a large-scale, multi-site, prospective, observational registry. All patients with a solid tumor malignancy who receive Ataraxis testing as part of routine clinical care are eligible for enrollment, which will link Ataraxis test results with short- and long-term patient outcomes to evaluate the real-world performance and clinical utility of Ataraxis tests. The ARC Registry utilizes an adaptable design, where additional Sponsor-led analyses and investigator-initiated ancillary studies can be added after the initial study is opened.

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).

The purpose of this study is to evaluate the efficacy and safety of inavolisib in combination with fulvestrant compared with inavolisib in combination with fulvestrant in participants with PIK3CA-mutated, HR-positive, HER2-negative locally advanced or metastatic breast cancer (LA/mBC) in the post-cyclin-dependent kinase inhibitor (CDKi) setting.

The goal of this clinical trial is to evaluate the safety and efficacy of 3 different dose levels of CLR 125 in patients with advanced triple negative breast cancer. The main questions the study aims to answer are: * What dose and regimen should be used in future trials of CLR 125 in patients with advanced triple negative breast cancer. * What side effects do participants have when taking CLR 125. Participants will: * Have CLR 125 administered via infusion 4 times each cycle; repeated every 8 weeks. * Visit the clinic once every 3 weeks for checkups and testing. * Report any side effects or new medications. Some participants may also receive one dose of CLR 131 to evaluate the amount of radiation delivered to various organs and to the tumor. These participants will: * Have 4 scans completed over 2 weeks * Have blood drawn 6 times over 2 weeks.

The purpose of this study is to assess the safety of GDC-4198 alone and in combination with giredestrant and also the efficacy of GDC-4198 + giredestrant versus abemaciclib + giredestrant in participants with locally advanced or metastatic ER+, HER2- breast cancer. The study consists of 2 phases: Phase Ib and Phase II. Phase Ib will evaluate the safety and pharmacokinetics (PK) of GDC-4198 alone and in combination with giredestrant. Phase II stage will compare the activity and safety of GDC-4198 and giredestrant with abemaciclib and giredestrant.

Enhanced Recovery After Surgery (ERAS) protocols have been of increasing interest in the surgical community for decades. The emphasis has been development of protocols to maximize pain control post-operatively without the use of opioids. While this approach has been studied extensively in the oncology surgery literature, little data exists on the utility of ERAS protocols in the setting of breast conserving surgery (BCS), which is a type of surgery to remove breast cancer while saving as much of the breast as possible. The purpose of this study is to determine the utility of implementing ERAS protocols in breast cancer patients undergoing breast conserving surgery. Study participants will be randomized to either ERAS protocol or standard peri-operative care without ERAS. The study will assess the how many opioid prescriptions are given in the first week after surgery and how much pain participants report right after surgery. Investigators will also look at how long participants stay in the recovery room and if medicine for nausea is needed.

This study will evaluate the efficacy and safety of the combination of inavolisib plus a cyclin-dependent kinase 4 and 6 inhibitor (CDK4/6i) and letrozole versus placebo plus a CDK4/6i and letrozole in the first-line setting in participants with endocrine-sensitive PIK3CA-mutated hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-), advanced breast cancer (ABC).

The aim of this study is to demonstrate if it is possible to delivering a novel and modern radiotherapy approach (Dose Escalated internal PTV (DE-iPTV)) and to collect health related quality of life in patients whose breast cancer has spread to the brain (brain metastases) at 8 weeks post enrolling into the study. The main questions that have been set out to to answer are: * Is it possible to deliver the novel radiotherapy approach, DE-iPTV? * Is it possible to measure health -related quality of life? * What impact does the novel radiotherapy approach have on: patient's quality of life, control of the brain metastasis (control of the lesion) and steroid use? Participants will: * Receive 5 doses of radiotherapy * Complete weekly quality of life (EQ-5D) assessments and medication (steroid) diaries (via telephone/ postal) until 12 weeks post enrolment * Be reviewed in clinic with up-to-date MRI scans at 8, 12 and 24 weeks post-enrolment * Complete a more detailed HRQoL panel of assessments will be assessed at baseline, 8 weeks, 12 weeks and 24 weeks post enrolment.

To evaluate the diagnostic performance of Tc99m sestamibi (MBI) compared to breast MRI in women who are at high risk for developing breast cancer. To assess the relationship of tumor size, histologic subtype and location of lesion and how it affects lesion conspicuity and sensitivity in MBI detected cancers.

Breast arterial calcification (BAC) is a common incidental finding on screening mammograms and has been associated with cardiovascular disease in women. However, every study in this field has been imaging-based. The accuracy of mammography for detecting breast arterial calcification has only ever been measured against another radiologist reading the same mammogram, never against the tissue itself. As a result, it is not known how much calcification mammography misses, nor whether what it shows represents medial (Monckeberg-type) calcification or true atherosclerosis. This prospective observational study compares mammographic BAC with the histopathology of breast arteries obtained from mastectomy specimens. Women aged 40 years and older undergoing upfront mastectomy, without neoadjuvant therapy, for invasive breast cancer or ductal carcinoma in situ will be enrolled consecutively. Additional tissue blocks will be taken from tumour-free areas of the specimen and examined with von Kossa and elastic van Gieson stains to determine whether arterial calcification is present and whether it lies in the media or the intima. These findings will be compared with the preoperative mammogram, which is read independently and blind to the pathology result. As a secondary and exploratory objective, coronary artery calcification will be scored from staging computed tomography images already acquired for cancer staging. No additional tests, imaging, radiation exposure or blood sampling will be performed for the purposes of this study, and the surgical procedure will not be altered in any way.

The purpose of the study is to characterize baseline multidisciplinary tumor board (MDTB) context and variability, evaluate the relationship between baseline fitness of patients with cancer and initial treatment recommendations, and assess the impact of the INSPIRE intervention, which involves including electronic patient reported outcomes (ePROs) within MDTB on MDTB discussion content, provider burden, treatment recommended and received, healthcare utilization, and patient-reported outcomes.
