Filter by:This was a non-interventional (observational), retrospective, cohort study of women with hormone receptor (HR)-positive and human epidermal growth factor receptor-type 2 (HER2)-negative advanced breast cancer who started treatment with cyclin-dependent kinase inhibitors (CDKi) 4/6 (ribociclib or palbociclib) in Portugal. This was a study of medication use patterns, based on information from the hospital pharmacies of the participating centers. Patients who started a CDKi 4/6 (ribociclib or palbociclib) between 1 March 2019 and 31 December 2019 were included and followed through 24 months. A follow-up occurred 6 months after the start of CDKi 4/6 (ribociclib or palbociclib) to quantify the occurrence of dose changes.
This interventional, post-market, multicenter clinical investigation is designed to evaluate the performance of a custom-made medical device, "the Breast Cancer Locator (BCL)" in Subjects with non-palpable breast cancer, in Europe.
This was a retrospective cohort study which included all histologically proven cases of breast cancer in the 2 years from January 2022- December 2023 at a tertiary care centre. This study was performed in line with STROCSS criteria. The following clinicopathological data was retrieved from the histopathological records- age, tumor size, nodal involvement, lymphovascular/ perineural invasion, and Bloom Richardson grading. Routine histopathological processing was done followed by immunohistochemical analysis for ER, PR, HER2, Ki67 and AR. All the cases were categorised into Luminal A, B, Her2 enriched and triple-negative breast cancer based on the surrogate molecular classification. Further, all the cases were categorised into HER2 negative (no staining or incomplete weak membrane staining in ≤10% tumor cells), HER2 3+ (complete membranous staining) and HER2 low (1-2+ staining without amplification on ISH) based on consensus of two pathology consultants. The present study aims to evaluate the clinicopathological parameters of the HER2 low breast cancers.

Breast cancer is a leading cause of death among women globally, with significant incidence in Egypt. It is characterized by aggressive behavior and resistance to treatment, necessitating early detection methods. Research has revealed that many cancer-related mutations are in non-coding DNA, including microRNAs (miRNAs) and long non-coding RNAs (LncRNAs). miRNAs like miR-185-3p and miR-301a, and LncRNAs such as LINC00511, are potential biomarkers for cancer diagnosis due to their roles in gene regulation and stability in circulation. This study aims to explore the diagnostic utility of these biomarkers in breast cancer.
The effectiveness of breast cancer treatment is quite well documented. Still, side effects can underpin other treatment-induced diseases such as osteopenia, diabetes, and especially cardiovascular dysfunction. Therefore, finding a method that could partly counteract these side effects and at the same time be implemented throughout treatment is a challenge for researchers. The main purpose of this experimental, randomized control trial was to analyze the effect of the Pilates Method (PM) intervention on changing the myofascial stiffness along the thoracic and lumbar spine, cardiorespiratory fitness and quality of life in women with breast cancer receiving aromatase inhibitor therapy. The apllied procedure of 12 -week PM training included the training intervention based on hypothesis: - PM reduces myofascial stiffness along the thoracic and lumbar spine of women with breast cancer receiving aromatase inhibitor therapy - PM improves the cardiorespiratory fitness of women with breast cancer receiving aromatase inhibitor therapy - PM improves the quality of life of women with breast cancer receiving aromatase inhibitor therapy. Possible practical applications include the domains of exercise medicine, physical activity in cancer and public health.
Supervised, prescribed exercise has positive effects on body composition, physical functioning, psychological wellbeing and quality of life for patients after breast cancer treatment. However, exercise interventions are often time consuming, commonly take place at a health or fitness facility, and usually require a trained professional to be present. Cost-effective, enjoyable and practical approaches, that can be adopted at home or in local surroundings are needed. For example, an alternative approach is using an electronic physical activity tracking wristwatch to help patients engage with exercise or physical activity. Research demonstrates the importance of structured and supervised exercise for breast cancer survivors. However, it is not known whether other approaches (e.g. home-based exercise and physical activity) alongside the use of personalised technology-enabled feedback, can cause similar improvements to health when compared to structured exercise. The overall aim of this study is to determine whether cardiorespiratory fitness is changed by a technology enabled, remotely delivered exercise intervention and to determine whether this change is similar to the change caused by a partly supervised, prescribed exercise intervention. This study will also determine the influence of both interventions on physical functioning, body composition and blood pressure.
The goal of this observational study is to learn about the effects of metronomic chemotherapy in advanced breast cancer patients. The main question it aims to answer is: How effective is metronomic chemotherapy in advanced breast cancer? Specific benefit groups of metronomic chemotherapy.
BACKGROUND AND CURRENT STATUS: Advancements in neoadjuvant systemic treatments (NST) for HER2 positive and triple-negative (TN) breast cancer (BC) subtypes have led to high rates of pathologic complete response (pCR), raising questions about the necessity of subsequent surgery, especially for those undergoing adjuvant radiotherapy. While Magnetic Resonance Imaging (MRI) remains the most effective imaging technique for assessing neoadjuvant treatment response, surgery is still required to confirm pCR in cases of almost complete or complete MRI response (iCR). To safely avoid surgery in these BC "exceptional responders," a technique with high negative predictive value is imperative. OBJECTIVE: This study aims to establish the diagnostic efficacy of image-guided vacuum-assisted biopsy (VAB) in assessing pathological complete response (pCR) after NST in HER2 positive or TN breast cancer subtypes, particularly those showing post NST-MRI complete or almost complete response. METHODS: A prospective study was conducted at "Hospital Universitario 12 de Octubre de Madrid" from June 25, 2018, to October 25, 2029. Twenty-five patients with HER2-positive or TN operable invasive ductal carcinoma (IDC) BC subtype, at stages cT1-3/N0-2 undergoing primary NST and showing complete or almost complete response on post NST-MRI, were enrolled. Ultrasound or stereotactic-guided vacuum-assisted biopsy (VAB) of the previous clip and tumor bed area was performed before surgery. VAB pathological results were compared with surgical pathological results to evaluate the diagnostic efficacy of predicting pCR with VAB after NST. Pathological representativeness of the VAB sample was ensured. pCR was defined as the absence of invasive ductal carcinoma and in situ ductal carcinoma.
According to a news published by the World Health Organization (WHO); More than 2.3 million cases of breast cancer occur each year, making it the most common cancer among adults. In 95% of all countries, breast cancer is the first or second cause of female cancer death. In 2020, 2.3 million women worldwide were diagnosed with breast cancer and 685,000 deaths occurred. In Turkey, breast cancer ranks first among the most common cancer types in women, and the number of breast cancer cases in women in 2020 was recorded as 74 638. As a result of this situation, WHO (2023) published the Global Breast Cancer Initiative Framework to save 2.5 million lives from breast cancer by 2040. This published framework includes health promotion for early detection, timely diagnosis and comprehensive management of breast cancer. One of the most effective ways to reduce breast cancer mortality and morbidity rate is early diagnosis. It is important to determine early diagnosis and signs and symptoms of cancer before they appear. Early diagnosis of breast cancer is possible with breast self-examination (BSE), clinical breast examination and mammography. Breast self-examination is an important examination method in terms of detecting changes in breast tissue and preventing subsequent complications. It is also an easy-to-apply, cheap and non-invasive method. In Turkey, it is recommended that women regularly perform breast self-examination every month after the age of 20, women between the ages of 20 and 40 should have a clinical breast examination every two years, and women between the ages of 40 and 69 should have a clinical breast examination every year and have a mammogram every two years. There are studies showing that fear of breast cancer has a positive and negative impact on early diagnosis behaviors. Champion et al. (2004) stated that women with moderate breast cancer fear had a high rate of early detection behavior, whereas low and high fear levels had a negative effect on behavior. In the study conducted by Yavan et al. (2010) on 188 women, 2% of the women. They found that 3 of them had regular BSE and 78.7% of them had never had a mammography. In addition, 85% of the women included in the study stated that they had a fear of breast cancer due to a family history of breast cancer, being diagnosed with breast cancer, and the presence of risk factors. Study results show that fear of breast cancer affects screening results. Therefore, aim in the study is; To determine the effect of breast cancer and BSE training given to women on breast cancer fear and BSE skills.
