Filter by:This is a phase Ⅲ, double-blind, randomized, parallel-controlled, multicenter equivalence study to compare the efficacy and safety of SYSA1901 + trastuzumab + docetaxel vs. Perjeta® + trastuzumab + docetaxel in the participants with early-stage or locally advanced HER2-positive and HR-negative breast cancer with a primary tumor > 2 cm.
This is a prospective observational multicentric study. The aim is to evaluate the incidence of endometrial cancer and endometrial atypical hyperplasia in patients with previous breast cancer, treated with different adjuvant therapies. The second aim is to identify ultrasonographic soft markers related with endometrial cancer or atipycal hyperplasia.
This study aims to evaluate Effectiveness of Lunit INSIGHT DBT in the assistance of detection and diagnosis of breast cancer during 3D mammography interpretation
In this study, investigators will compare standard Aerobic Training/AT with adaptive Aerobic Training/AT. Standard AT will be a fixed (unchanging) amount of walking each week, while adaptive AT will adjust the level of exercise depending on participants' response to the exercise. Investigators will see how both study approaches (standard AT and adaptive AT) affect participants' CRF.
The investigators propose to deliver a pilot randomized controlled trial to 40 women newly diagnosed with breast cancer and scheduled to undergo chemotherapy. The current objectives are: 1) to evaluate the preliminary efficacy of the prehabilitation physical activity (PA) intervention delivered by a physical therapist and 2) assess the intervention's feasibility, acceptability, and appropriateness. The long-term goal is to scale this intervention for implementation into the standard of cancer care to prevent, mitigate, and treat cancer-related cognitive decline (CRCD).
Determine whether subjects harboring ESR1-mutant/amplified breast cancer have a higher rate of clinical benefit from 17b-estradiol therapy than subjects with ESR1-wild-type breast cancer
Background: Mastectomies are traditionally performed under general anesthesia (GA), often with the addition of regional anesthesia for post-operative pain relief. Thoracic paravertebral blocks (TPVB) had previously been described in the literature to be sufficient for intra-operative anesthesia as an alternative to GA. A 2021 literature review by Cochrane Library comparing paravertebral anesthesia (with or without sedation) to general anesthesia for patients undergoing oncologic breast surgery showed that TPVB could reduce post-operative nausea and vomiting (PONV), hospital stay, postoperative pain and time to ambulation. It also resulted in greater patient satisfaction compared to GA. The aim of this study is to demonstrate the efficacy of single-injection TPVB done under ultrasound guidance for patients undergoing breast cancer surgery without axillary node dissection. Hypothesis: Single-injection thoracic paravertebral block is non-inferior to multiple (3) injections for oncologic unilateral breast surgery anesthesia. Methods: The current study is a prospective randomized controlled trial of patients undergoing oncologic breast surgery without axillary node dissection or immediate reconstruction. Patients will be randomized into two groups; thoracic paravertebral block (TPVB) single-injection or TPVB multiple (three) injections. Significance/Importance: Oncologic breast surgery performed under TPVB and sedation lowers the risks of post-operative nausea and vomiting, decreases peri-operative use of narcotics, decreases pain scores at rest and on mobilization and leads to better overall patient satisfaction when compared to GA. It also leads to shorter hospital stays. Most studies use multiple injections to perform the block. Even though the risks associated with TPVB are low (3.6 per 1000 surgeries), the single-injection technique could reduce the risks even more. One injection is also easier to perform and of shorter duration, leading to greater patient tolerance and less side effects related to blocks performance duration such as vaso-vagal reactions or general discomfort. To date, no studies have compared the efficacy of single-injection paravertebral block and multiple injection techniques as the main modality of anesthesia for breast cancer surgery.
This study is a Phase 2 open label, single arm, adaptive multi-centre trial. Patients with early stage HER2-positive breast cancer will receive neoadjuvant treatment of trastuzumab deruxtecan (T-DXd) 5.4mg/kg intravenously every three weeks for up to six cycles.
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.
The purpose of this study is to explore risk factors for grade 4 neutropenia in users of the study medicine Palbociclib for the potential treatment of Palbociclib. This study is seeking participants: - treated with the study medicine Palbociclib - having any breast cancer records in same month as the initiation date - having prescription records of palbociclib from 15 December 2017 to 29 February 2024 The study design is a nested case control study. This study design uses de-identified patient data from a hospital based electronic medical record and claim database in Japan. This design was selected since the primary objective is to explore risk factors of Grade 4 neutropenia in users of the study medicine Palbociclib. One of the important side effects of taking Palbociclib is neutropenia (decreased count of neutrophils - a type of white blood cell). In this study the effect of Palbociclib in decreasing the neutrophil count was studied after it was released to the market. To do that, the study gathered details of breast cancer patients newly treated with Palbociclib from 23 hospitals and 10 medical institutes across Japan. The below patient details were collected: - dose of Palbociclib - other medicines prescribed for cancer - age - gender - past information on cancer treatments - laboratory findings at baseline The result was based on the neutrophil count collected from the laboratory data. Around 1300 patients newly treated with Palbociclib for breast cancer was calculated by the medical information database network (MID-NET) in 6 years from 15 December 2017. Patients who develop grade 4 neutropenia after palbociclib initiation will be matched to controls who do not develop grade 4 neutropenia. A statistical model will be used to explore risk factors of grade 4 neutropenia adjusted for important potential confounding factors.
