Filter by:To improve the health and quality of life of breast cancer (BC) patients, researchers are focusing on prehabilitation strategies like physical exercise, preparing patients both mentally and physically for clinical and surgical procedures, potentially reducing complications. Physical exercise is also recognized as pivotal in optimizing chemotherapy. It can improve blood flow and oxygen supply in the microenvironment of the tumor (MT), potentially enhancing chemotherapy effectiveness. Although previous research has shown the benefits of preoperative exercise combined with chemotherapy in various cancer types, including BC, further investigation is needed into the exact effects of prehabilitation exercise (PE) on MT physiology. This study aims to provide valuable insights into the potential benefits of PE for BC patients and its impact on the tumor microenvironment. The hypothesis is that PE in BC patients will improve their quality of life, reduce fatigue, increase muscle mass, decrease fat mass, and enhance physical fitness. Additionally, beneficial acute hemodynamic changes, particularly increased blood flow following PE sessions, and hemodynamic adaptations involving higher levels of oxygenated hemoglobin, increased blood flow, greater oxygen saturation, and a higher metabolic rate of oxygen, are expected. The study will include 76 participants aged 18-65 years, meeting specific criteria such as a diagnosis of hormone receptor-positive BC, no medical contraindications for exercise, no metastatic cancer, and no structured exercise in the last six months. These participants will be randomly assigned to a PE group or a control group. The study will consist of three phases: Phase 1 involves pre-intervention assessments, Phase 2 includes a 4-week PE intervention with three weekly sessions, and Phase 3 encompasses post-intervention and post-surgery assessments. The 4-week PE intervention in Phase 2 will include strength and aerobic training. Quality of life and fatigue assessments will use questionnaires, and measurements will be made for fat mass, lean mass, bone density, and cardiorespiratory fitness. Strength measurements will be taken, and shoulder mobility will be evaluated. Hemodynamics of the MT will be assessed using a hybrid device combining Near-Infrared Spectroscopy and Diffuse Correlation Spectroscopy with ultrasound.
Currently, F-18 FDG PET/CT is routinely used for breast cancer staging and treatment response assessment. Most breast cancers express Estrogen Receptor (ER) and Progesterone Receptor (PR) and this subtype shows lower activity on FDG imaging. 68Ga DOTATATE PET/CT is an effective imaging option for somatostatin receptor (SSTR) positive neuroendocrine tumors. There are case reports showing 68Ga DOTATATE uptake in non-Hodgkin lymphoma, meningioma, breast cancer, thyroid adenoma and papillary carcinoma. There are also histochemical studies showing that SSTR is a potential radiopharmaceutical target for ER+/PR+ breast cancer . Its hypothesized that 68Ga DOTATATE PET/CT may be superior to 18F FDG PET/CT primarily in hormone receptor (HR) positive breast cancer. In this study, its aimed to compare the uptake pattern of breast cancer lesions and HR status with 68Ga DOTATATE and 18F FDG uptake in lesions.
Long non-coding RNAs (lncRNAs) play an important role in different types of cancer, including breast cancer, through regulation of gene expression and epigenetic signatures. Genetic variations such as single nucleotide polymorphisms (SNPs) in lncRNAs have been found to be associated with cancer. Our aim was to provide information about the role of LINC00511 SNPs (rs11657109 or rs17780195 or rs9906859, rs4432291 and rs1558535) in breast cancer susceptibility in the Egyptian population.
The aim of this trial is to explore the real-world effectiveness and poteintial predictors of Sacituzumab Govitecan in Chinese metastatic breast cancer patients.
Breast cancer is the most common malignant tumour among females with an incidence of about 2.1 million women every year.Nearly about 40-60% of breast surgery patients develop severe acute postoperative pain.⁴ Opioids are the current best standard drugs for postoperative pain relief, however, exposure to large doses of opioids leads to multiple side effects like prolonged sedation, respiratory depression, nausea, and vomiting.We are comparing two different drugs and their combination for perioperative analgesia for MRM. This work is a comparative study that aims to compare the analgesic effects of perioperative IV infusion of dexmedetomidine, preoperative oral gabapentin, and their combination in patients undergoing modified radical mastectomy surgery regarding the time of first rescue analgesia, postoperative morphine consumption, and possible complications.
The purpose of this study is to evaluate the effectiveness of lesion detection and diagnosis-aiding software (CadAI-B for Breast) during ultrasound (US) examination
Breast cancer remains the most frequent type of cancer globally. Nevertheless, the increased rate of disease-free survival of breast cancer brought the specific need of managing of short and long-term side effects of multimodal treatment. Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most debilitating conditions which is characterized by a wide variety of experienceable symptoms by patients that need to be addressed in detail. Therefore, in this cross-sectional study, it was aimed to assess the potential symptoms associated with CIPN of patients with breast cancer who underwent systemic chemotherapy. In addition, it was aimed to assess the potential associations between experienced symptoms of CIPN and sociodemographic (age, body mass index etc.) and clinical features (mean exposed dose, type of surgery (if any) etc.).
Patient report complication data to our best knowledge has not been studied yet in electronic consent. This study is a feasibility study to assess whether patients will reliably report their complications, the quality of this reporting and whether the information provided in the consent form matches up to their experience. This data will then be used to improve the consent process and evaluate whether the Patient Initiated Follow Up (PIFU) model is effective or if it leads to underreporting of problems.
This research is being done to evaluate the safety and effectiveness of a drug currently known as Azenosertib (ZN-C3) in combination with the drugs carboplatin and pembrolizumab in metastatic triple-negative breast cancer. The names of the study drugs involved in this study are: - Azenosertib (a type of WEE1 inhibitor) - Carboplatin (a type of platinum compound) - Pembrolizumab (a type of monoclonal antibody)
This clinical trial evaluates a patient navigation program for addressing disparities in breast cancer care. The navigation program is designed to help improve patient knowledge about clinical and supportive care services, navigate to existing services, help manage barriers to care, and enhance patient skills related to management of cancer treatment. Offering a patient navigation program may increase health equity and improve social needs and quality of life over time for newly diagnosed breast cancer patients.
