Filter by:Persistent pain after breast cancer surgery is frequently observed in more than 60% of patients.The suboptimal management of perioperative pain can lead to the occurrence of persistent breast cancer pain syndrome and phantom breast pain. Dexmedetomidine, a novel α2-agonist with an eight-fold affinity for α2-adrenergic receptors (sedate and analgesic effects) as clonidine, while exerts much less α1-effects., has been found to significantly increase the duration of peripheral nerve blocks, with minimal systemic side effects. Ketamine is a non-competitive antagonist of the N-methyl-D-aspartate (NMDA) receptors. It is used for sedation, premedication, induction, and maintenance of general anesthesia. Central, regional, and local anesthetic and analgesic properties have been reported for ketamine. Both can be used through Erector spinae plane block for postoperative pain control.
From 2021 to 2022, 31 patients with unifocal breast cancer were enrolled for precision breast conserving surgery (PBCS) guided by wire guided localization (WGL) combined with CT guided 3D reconstruction. Surrounded WGL was performed under local anesthesia, followed by an immediate contrast enhanced CT scan. PBCS guided by CT guided 3D reconstruction was performed one day after the localization. Women who underwent palpation guided breast conserving surgery (BCS) were included as control. Two-sided Student t test, Fisher's exact test and chi-square test was applied.
Accurate evaluation of tumor boundaries in breast-conserving surgery is critical to reducing the second operation of patients. Near-infrared (NIR) fluorescence imaging using molecular agents has shown promise for in situ imaging during resection. However, very effective probes can be applied to clinical trials up to now, which limits the clinical application of fluorescence imaging. Here we developed a new technology that can quickly identify the tumor area of the resected breast tissue during the operation and distinguish the tumor boundary. In brief, the breast tissues were incubated with the probe immediately after intraoperative resection and imaged to identify the tumor area and distinguish the tumor boundary. The accuracy of fluorescence imaging was confirmed by pathological diagnosis.
Women living with and beyond breast cancer are at a heightened risk for experiencing adverse mental health outcomes and declines in cognitive function following chemotherapy treatment. Women living with and beyond breast cancer have reported increased levels of anxiety and depression during the COVID-19 pandemic which may have significantly impacted their quality of life (QoL). Physical activity (PA) may be used to manage mental health and improve cognitive function in women living with and beyond breast cancer. Research is needed to assess the feasibility of a supervised, remotely delivered, combined (i.e., aerobic + resistance) exercise program to improve cognitive function and manage adverse mental health in women living with and beyond breast cancer. This study will pilot an 8-week, remotely delivered, combined (i.e., aerobic + resistance) exercise and behavioural counselling intervention on cognitive function and mental health outcomes (i.e.,anxiety, depression, self-efficacy and self esteem) in women living with breast cancer who received chemotherapy treatment within 12-48 months.
The primary objective of this study is to examine how exposure to "pinkwashed" alcohol advertisements (i.e., ads that associate the company with breast cancer awareness or charities) affects consumers' perceptions that alcohol increases the risk of breast cancer. The investigators will randomize participants to view 3 'pinkwashed' social media advertisements for alcohol or 3 control advertisements for alcohol (i.e., 'de-pinked' standard alcohol advertisements that match the intervention advertisements on overall design but do not mention breast cancer). Each participant will view the 3 advertisements for their arm (presented in random order) and respond to survey questions programmed in Qualtrics.
An open-label, single center study with 99mTc-DARPinG3 SPECT/CT and biopsies of primary tumour and metastatic lymph nodes in breast cancer patients, where the primary endpoint of the study is to find out the correlation between the HER2 expression measured by 99mTc-DARPinG3 SPECT/CT and standard histopathology from relevant tumor and lymph node biopsies.
Background: In postmenopausal women, an alteration in body composition occurs as a consequence of the secretion of low levels of serum estrogens by the ovaries. Observing an increase in abdominal and mammary fat mass and a decrease in skeletal muscle mass, which is also accompanied by loss of muscle strength and physical function, which leads early to a sarcopenia. On the other hand, the increase in estrogen production by adipose tissue has been associated with an increased risk of breast cancer during menopause because the mammary parenchyma is particularly sensitive to this type of estrogen. For this reason, Hormone Therapy (Aromatase Inhibitors and Tamoxifen) is prescribed in women with estrogen receptor-positive breast cancer. Antineoplastic treatments (Chemotherapy and Hormonal Therapy) have contributed to non-metastatic breast cancer currently presenting a high survival rate, not without adverse effects associated with the course of the disease, age and antineoplastic treatment, affecting various systems, but particularly skeletal muscle mass. Therefore, resistance exercise training has been proposed as an effective intervention strategy to increase muscle mass and strength in different populations. However, the level of muscle response to this type of training in postmenopausal women survivors of breast cancer with and without hormone treatment (Aromatase Inhibitors and Tamoxifen) is unknown.
Aim of this trial is to define if Trend of Four (TOF) values after a bolus of rocuronium is correlated with Bispectral Index BIS values during standard general anaesthesia for breast surgery.
The goal of this clinical trial is to test the efficiency of Autotaxin (ATX) as a biomarker for breast cancer patients. The main questions it aims to answer are; - is ATX a reliable tumor marker for breast cancer patients in diagnosis - can ATX differentiate cancer patients from non-cancer ones
The aim of our study is to investigate the effect of vibration therapy to be applied to patients undergoing breast cancer surgery and adjuvant radiotherapy on upper extremity joint range of motion, muscle strength, grip strength, pain, functionality, and quality of life.
