Active clinical trials for "Breast Neoplasms"

Explosive growth in the use of telemedicine (video or telephone visits) has followed the onset of the coronavirus disease 2019 (COVID-19) pandemic in order to meet healthcare needs while avoiding unnecessary exposure risks in ambulatory care spaces. Accordingly, in March 2020, the Centers for Medicare & Medicaid Services expanded reimbursement for telemedicine visits to equal that of in-person services. The policy and infrastructure that enabled this emergency transition is laying the groundwork for enduring expansion of elective telemedicine, a technology that could significantly decrease the burden of medical care in older patients with cancer. To benefit from telehealth, patients must have a certain level of knowledge and capacity to engage with technology, which can be a challenge for some older adults because of inexperience, access, and disability. As cancer is mainly a disease of older adults, with a median age of 65 at diagnosis for most cancer types, this is a significant limitation on the utility of telemedicine in oncology. The goal of our study is to better understand older breast cancer patients' experiences with telephone and video telemedicine with regard to visit convenience, completeness, and interpersonal satisfaction through semi-structured interviews with patients.

This study is a retrospective, multi-site, patient-level medical chart review of US adult patients with locally advanced or metastatic breast cancer (ABC) who initiated talazoparib on or after October 16, 2018 and were managed by participating providers from Cardinal Health's Oncology Provider Extended Network (OPEN). This study will describe patient characteristics, treatment patterns, and clinical outcomes of talazoparib-treated patients in real-world practice setting in US. The primary population for this study includes: -HER2-negative ABC patients with germline BRCA1/2 (gBRCA1/2) mutations treated with talazoparib monotherapy initiated on or after October 16, 2018 and ≥18 years of age at initiation of talazoparib.

The study aim is to determine the allele frequencies of 1236 G>A and 3435 G>A in ABCB1 and study their association with the incidence and severity of paclitaxel-induced peripheral neuropathy while adjusting for other baseline covariates in Egyptian patients. Additionally, the study aimed at fitting and validating logistic regression models with the aforementioned SNPs evaluated in additive, dominant, overdominant, and recessive genetic models and performing diagnostics for the best model in terms of internal validity.

Background Radio Isotopes and Blue dye alone or in combination are the most commonly used tracer agents in sentinel Node Biopsy for early breast cancer. Recent studies have found fluorescence method using Indo Cyanine Green as a promising technology with fewer disadvantages. This study represents the first within a North African setting. Methods Retrospective analysis of our database that includes patients with clinically node-negative breast cancer scheduled for breast surgery and SN biopsy between 2016 and January 2021. Patients who underwent detection using fluorescence-ICG were included in this study.

The purpose of this observational study is to assess whether the use of AI (Transpara®) can lead to an improved quality of a double reading mammography screening program. This is investigated by performing AI as a third reader and as a decision support during the consensus meeting, compared with conventional mammography screening (double reading and consensus without AI).

A multicentre prospective comparative study, comparing the use of various markers (magnetic marker Magseed, iodine seed 125I, carbon suspension) for marking a pathological lymph node in patients with breast carcinoma prior to neoadjuvant therapy and subsequent surgical treatment consisting of targeted axillary dissection.

To make an inventory of the physiotherapeutic care and the post-operative complications of patients who have undergone lumpectomy, sentinel node and radiotherapy treatment. The investigators expect to see a lack of consultation of physiotherapists by patients despite a significant number of complications, impacting the quality of life.

Contrast-enhanced magnetic resonance imaging (CE-MRI) is now established as the most accurate non-invasive imaging modality for characterizing breast cancer. CE-MRI has a very high sensitivity because the intravenous MR contrast agent highlights regions with increased vascularization and vascular permeability compared to normal breast tissues and benign lesions.

This study aimed to evaluate the feasibility of dual sentinel node staining method using mixture of indocyanine green(ICG) and radioisotope (RI) in breast cancer patients who receive neoadjuvant chemotherapy. Over the past few years, several studies have found using methylene blue, isosulfan blue, indocyanine green or radioisotope alone by detection method had several disadvantages. In this study we expects using mixture of indocyanine green (ICG) with radioisotope (RI) has potential to improve sentinel lymph node (SLN) mapping in breast cancer patients who receive neoadjuvant chemotherapy.

In the proposed project the investigators will asses whether changes in expression of selected circulating microRNAs in serum could comprise a sensitive and specific biomarker of cardiotoxicity in cancer patients treated with anthracyclines based chemotherapy.
