Active clinical trials for "Breast Neoplasms"

This study will collect real-world clinical and patient reported outcomes (PRO) and diary data from eligible patients with documented Human Epidermal Growth Factor Receptor 2 (HER2+) [globally] or HER2-low [North America only] in routine clinical practice.

The ETERNITY study is an international, multicenter, observational study that aims to follow up patients who have participated in a GBG trial for early breast cancer, even after the study has officially ended, in order to collect long-term data on survival, late or delayed adverse events, in addition to information related to pregnancy, fertility and other parameters impacting quality of life.

The goal of this observational study aims to observe and evaluate the efficacy and safety of a liposomal doxorubicin containing regimen in the postoperative adjuvant treatment of breast cancer patients.

Hypoxia and reduced oxygen partial pressure is commonly occurring after abdominal surgery. This study aims to investigate whether similar changes also occur after breast cancer surgery. Inclusion: 60 women undergoing breast cancer surgery. Exclusion: Dementia or cognitive impairment that makes it impossible to participate in the study. Arterial blood gas and lung function are undertaken before surgery and the day after surgery

The purpose of this study is to analysis the fluorescence image of the breast sentinel lymph node (SLN) using Indocyanine green (ICG). Moreover, to investigate whether an artificial intelligence protocol was suitable for identifying metastatic status of SLN during the surgery, and evaluate the diagnosis consistency of the AI technique and pathological examinations for lymph node with and without metastasis.

This study intends to further evaluate the efficacy of acupuncture by comparing the intervention effects of different acupuncture treatment regimens on hot flashes in breast cancer ; and to explore the central effect regulation mechanism of acupuncture intervention on hot flashes based on integrated PET/MRI technology.

This study is a window of opportunity clinical trial to evaluate the efficacy of giredestrant (GDC-9545) or tamoxifen in estrogen receptor-positive (ER[+])/human epidermal growth factor receptor 2-negative (HER2[-]) primary invasive adenocarcinoma of the breast with Ki67 level ≥ 10%. A total of 92 patients will be enrolled in this trial and randomized 1:1 in the arm A with giredestrant (GDC-9545) and the arm B with tamoxifen, with a total duration of treatment of 15 days. This study will analyze the efficacy of giredestrant (GDC-9545) as determined by Ki67 expression between baseline tumor biopsy samples and post-treatment biopsy samples.

This clinical trial tests how well phytocannabinoids (cannabidiol [CBD] and tetrahydrocannbinol [THC]) work in reducing chronic chemotherapy-induced peripheral neuropathy (CIPN) in breast and colon cancer survivors. Neuropathy is the most common neurological symptom reported by cancer patients due to treatment. A variety of pharmacologic treatments have been evaluated to alleviate CIPN symptoms; however, no definitive treatment has been found to successfully treat all the symptoms of CIPN. Therefore, investigators continue to seek other possible treatment options including cannabis. Phytocannabinoids may be a particularly useful intervention for cancer patients given the limited effective treatments for CIPN. In addition, cannabis-based medicines have become tremendously popular as both cancer patients and clinicians are seeking therapies with fewer potential risks of dependency and other side effects. This trial is being done to provide cancer patients and clinicians with reliable information to help guide their use of phytocannabinoids to manage the tremendous distress and pain experienced by many cancer patients, which impacts their long-term quality of life.

The goal of this pilot observational study is to learn about the feasibility of collecting patient-reported data and stool and blood samples from patients age 65 and older treated with aromatase inhibitor therapy for breast cancer. Participants will be treated with standard of care aromatase inhibitor therapy and will undergo serial phlebotomy, complete patient-reported questionnaires, and submit serial stool samples. The main exploratory translational questions it aims to obtain preliminary data for are: What are the effects of aromatase inhibitor therapy on biomarkers of aging? What are the effects of aromatase inhibitor therapy on the microbiome? These data will be used for the development of future definitive studies.

The study is being done to research if hydroxychloroquine can prevent chemotherapy induced peripheral neuropathy. Certain chemotherapy drugs, like paclitaxel, are known to cause neuropathy which can impact quality of life. Currently, there are no options for preventing peripheral neuropathy. In addition, there are no useful methods to assess peripheral nerve damage. This study will also explore using a study MRI of patients' feet prior to starting chemotherapy and after they have completed chemotherapy to see if there is any difference in their nerve structure.
