Filter by:Interfascial blocks score over regional anesthetic techniques such as Transversus Thoracic Plane Block and Pectoral Nerves (PECS) Block as they have no risk of sympathetic blockade, intrathecal or epidural spread, which may lead to hemodynamic instability and prolonged hospital stay. The transversus thoracic muscle plane block (TTP) block is a newly developed regional anesthesia technique which provides analgesia to the anterior chest wall. First described by Ueshima et al. in 2015, the TTP block is a single-shot nerve block that deposits local anesthetic in the transversus thoracic muscle plane between the internal intercostal and transversus thoracic muscles. TTP block targets the anterior branches of the intercostal nerves (T2-6). Pectoral plane blocks are recently described . PECS block involves deposition of local anesthetic drug between muscle planes. PECS I block, between Pectoralis Major and Minor at third rib level, and PECS II block, the drug is deposited between Pectoralis minor and Serratus anterior muscle. The pectoral nerves (PECS) block provides analgesia of the lateral mammary region, the intercostobrachial and lateral cutaneous branches of the intercostal nerves (T2-T6), the medial cutaneous nerve of the arm and forearm, and the long thoracic and thoracodorsal nerves. The modified PECS block produces excellent analgesia and can be used to provide balanced anesthesia.
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 (WHO, 2023; https://www.who.int/news/item/03-02-2023-who-launches-new-roadmap- on-breast-cancer). In our country, 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 (IARC, 2023). 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 (Kayar, 2019). Breast self-examination is an important examination method in terms of detecting changes in breast tissue and preventing subsequent complications (Abo Al-Shiekh et al., 2021). It is also an easy-to-apply, cheap and non-invasive method. In our country, 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 (Ministry of Health, 2019). . There are studies showing that fear of breast cancer has a positive and negative impact on early diagnosis behaviors (Champion et al., 2004; Yavan et al., 2010). 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, our 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.
The main purpose of this study is to develop a computer-aided prediction model for NAC treatment response. Based on the heterogeneity of internal parametric tumor composition commonly observed, this study will utilize the histologic characteristics and treatment response to investigate the image features as input data for predicting treatment response using Deep Learning technology. Using this technique, preoperative treatment evaluation may be facilitated by tumor heterogeneity analysis from developed dynamic radiomics, and the possibility of personal medicine can be realized not far ahead. In the first two years of this study using images from DCE-MRI, PET/CT and QDS-IR, we plan to develop the image processing algorithms, including segmenting breast and tumor region, extracting image feature which reflects angiogenic properties and permeability of tumor, which are highly correlated with NAC treatment response. During the third year of the project, the morphology and texture features from first two years can be combined for PET/MRI and prediction model can be achieved in accordance with the features extracted from dynamic features extraction using longitudinal images of PET/MRI.
The primary goal of this study is to improve cancer literacy in Black women living with HIV and ultimately improve breast and cervical cancer screening uptake. This study involves an educational intervention delivered virtually and in person, depending on the participants' preference.
The purpose of the study is to determine if 6 and 12 months of treatment with Tamoxifen at lower dose is superior to Exemestane at lower dose on quality of life.
In some cases of hormone receptor positive, human epidermal growth factor receptor 2 (HER2) negative early breast cancer the benefit of adding adjuvant chemotherapy to hormonal treatment, estimated on the basis of the classical clinico-pathological parameters, is unclear. In these cases the application of a genomic test could be useful in guiding the therapeutic choice.
The aim of this observational study is to comprehensively analyze the metabolites in plasma samples from multi-cancer patients using advanced mass spectrometry detection technology, in conjunction with metabolomics approaches. The goal is to construct a plasma metabolite database for multi-cancer patients. Simultaneously, we will delve into the exploration and validation of a series of metabolic biomarkers for early multi-cancer diagnosis. The objective is to establish a safer, more convenient, and more sensitive early screening method, thereby providing a reliable scientific foundation and critical evidence for improving the early diagnostic process for individuals at high risk of multi-cancer.
This study is designed to test the feasibility of two intervention on promoting early screening for breast cancer in rural Ghana. In one intervention, screening for breast cancer, diabetes and hypertension will be offered together. In another intervention, a series of sessions with men will be conducted with a goal to change gender attitudes and increase support to women. The investigators' long-term goal is to test these interventions in a large-scale randomized controlled trial. The specific aims of this feasibility study are to: 1) refine the study materials, including the curriculum for the sessions with men, by consulting with an expert advisory committee and a local committee, and 2) determine the feasibility of the two interventions in four clinic zones in Yilo-Krobo district in eastern Ghana (1 clinic in control, 1 clinic in the first intervention, and 2 in the second intervention). This trial registration is for the second specific aim.
This study evaluates the acute toxicity and feasibility of repeat breast conserving therapy with preoperative accelerated partial breast re-irradiation (PAPBI) in female patients aged 51 years or older with ipsilateral recurrent or second primary low-risk breast cancer.
