The primary objective of the investigators is to develop an integrated algorithm for surgical treatment of chronic lymphedema after breast cancer surgery. This will be achieved by retrospectively analysing a subgroup of patients who had breast cancer-related surgery prior to lymphedema.
The aim of the research is to evaluate clinical outcomes of a two stage muscle sparing prepectoral breast reconstruction using tissue expander (TE) entirely covered by an ADM. The authors aim to report surgical indications, technical tips, clinical and histological outcomes with the final objective of delineate a decision-making algorithm for immediate prosthetic breast reconstruction.
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.
The purpose of this study is to determine the effectiveness of a digital health program called AYA STEPS, which is designed to help adolescent and young adult (AYA) cancer survivors manage symptoms and engage in recommended follow-up care.
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. 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.
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.
