Active clinical trials for "Breast Neoplasms"

A cross-sectional, multicenter, and observational study designed to update clinical, pathological, and lifestyle information for a cohort of approximately 1245 breast cancer patients included in the epiGEICAM-01 study.

In estrogen receptor (ER)-positive breast cancer (BC), human epidermal growth factor receptor-2 (HER2)-low ones are reported to have distinct clinical and molecular features from those with HER2-zero or HER2-positive status. However, the association between HER2-low status with response to endocrine therapy is largely unknown. In this study, we included 518 ER-positive BC patients who received either neoadjuvant endocrine therapy (NET) or neoadjuvant chemotherapy (NCT). The pathologic complete response rate (pCR) of HER2-low and HER2-zero tumors re-sponding to neoadjuvant therapies were compared. The difference in disease-free survival (DFS) and overall survival (OS) between the two groups was also analyzed. The pCR (defined as ypT0/isNx) in HER2-low BCs and in HER2-zero BCs for NET cohort and NCT cohort were compared.

In this large-scale cross-sectional study, we evaluated disease-free survival (DFS), overall survival (OS), and clinicopathological characteristics of BC patients from 1991 to 2022, retrospectively. We recruited patients referred to the Cancer Research Center in Tehran, Iran, and their HER2 status, which is classified as HER2-low, HER2-positive, or HER2-negative, was obtained from prospectively maintained registries. we aimed to dive more deeply into the clinicopathological characteristics and survival features of HER2-low breast cancer patients and campared it with HER2-negative and HER2-positive groups. Question 1: Is HER2-low breast cancer (BC) a new subtype in the standard classification of BCs? Question 2: How is the DFS and OS rate of HER2-low breast cancer patients in comparison with HER2-negative and HER2-positive groups?

Sleep is essential for human function, immunity, and well-being. In the general population, sleep disturbance and insomnia cause significant health problems and impact on the quality of life of many individuals. The incidence of insomnia in cancer patients is disproportionality higher, with breast cancer patients experiencing prevalence rates ranging from 19% to 69%. The impact of insomnia on cancer patients' lives can be significant and is associated with depression, cancer-related fatigue, increased pain, reduced quality of life, decreased immunity, disease progression, and survival. To date, breast cancer studies show large variation in reported insomnia prevalence rates, and the severity of sleep complaints in these patients have been difficult to assess. Thus, these issues require further investigation using standardised and validated measures. In this observational study, we aim to investigate the prevalence and severity of insomnia in a cohort of breast cancer patients at the Christie Hospital using the Insomnia Severity Index (ISI), a validated measure for insomnia. This study will consist of two stages. In Stage 1, patients aged 18 and over, who provide informed consent and have a diagnosis of Stage I, II or III breast cancer in the previous 12 months will be asked to complete the validated ISI. Using the ISI, participants identified as having sleeping difficulties and/or insomnia will be invited to Stage 2 of the study. In this stage, participants will be asked to track their sleep each morning for 3 weeks using a digital sleep diary downloaded onto their own smartphone. They will also be asked to complete a series of questionnaires gathering information regarding their quality of life, well-being, and health. This research will provide a better understanding of sleeping patterns, sleeping difficulties and insomnia in patients with breast cancer, and in the long-term, help us design better treatments for patients with sleeping problems.

The validation of the HFRDIS questionnaire in French will allow the use in common practice of this questionnaire in consultation in order to have a concrete and reproducible assessment of the impact of hot flashes on the daily life of patients. This validation will also allow this questionnaire to be used in therapeutic trials to assess the effectiveness of a symptomatic treatment under study. The use of this questionnaire in patients on hormone therapy will allow for an overall assessment of the impact of hot flashes in their daily lives. There are no risks induced by participation in this research, it is only an observational study without change on the monitoring of participants in both cohorts.

This study is planned as a secondary data use (SDU) study and the data collection will be performed retrospectively. Patients who presented to the participating sites with metastatic breast cancer will be defined, and patients' data will be recorded into a database.

The investigators have developed a Discussion Prioritization Tool (DPT) for older adults consider adjuvant chemotherapy that utilizes Conjoint Analysis (CA) methodology and the objective of the current study is to assess usability of this DPT in the target population, older adults with breast cancer and to adapt the tool to optimize usability for the target population.

This study aims to describe in detail the patient journey from diagnosis to the beginning of treatment and patterns of care of hormone receptor- positive, HER2-negative de novo or recurrent metastatic breast cancer between January 2018 and December 2020 in Brazil.

Nipple-sparing mastectomy (NSM) with immediate breast reconstruction (IBR) is a form of mastectomy that achieves optimal disease control and facilitates reconstruction. The study aimed to assess the oncological safety and aesthetic outcomes of nipple-sparing mastectomy and immediate breast reconstruction. 35 female patients with breast cancer were included in the study. The investigators categorized the incisions into radial, inframammary, and periareolar incisions with planned reconstruction types; direct to implant (DTI), transversus rectus abdominis myocutaneous (TRAM) flap, latissimus dorsi myocutaneous (LD) flap, or LD with implant.

Researchers are trying to determine if the Mayo marker is easily seen with ultrasound making it easier, faster, and more accurate for preoperative localization of the biopsied positive lymph node.
