Filter by:The goal of this observational study is to screen and differentiate common cancers in participants with or without suspicious lesions. The main question the investigators aim to answer is: Can the developed model, using peripheral blood cell-free DNA sequencing, work well in screening and classifying common cancers especially in the early stages? Participants will undergo the collection of 15~20ml of blood and 1~2 telephone follow-up calls.
This study is a prospective, single-center, observational clinical study, The objection was to observe the treatment of pyrotinib combined with trastuzumab and neoadjuvant chemotherapy Efficacy of Stage II-III breast cancer and observation of the efficacy of step-down neoadjuvant therapy for HER2-positive stage T1cN0M0 breast cancer.
Breast cancer has the highest incidence rate among female cancers, and breast radiotherapy plays an essential role in the treatment of breast cancer. However, the acute and chronic skin reactions caused by radiotherapy, especially radiation dermatitis, have a significant impact on the physical and mental health of breast cancer patients. Severe acute radiation dermatitis can affect the patient's quality of life and may even lead to treatment interruption, thereby affecting treatment efficacy. Chronic radiation dermatitis can lead to irreversible skin problems, such as "radiation-irritated skin" and skin pigmentation, which can affect the quality of life of breast cancer patients after treatment. This study aimed to evaluate and examine the skin reactions of 30 breast cancer patients who underwent whole-breast radiotherapy after breast conserving surgery. The subjects returned to the hospital for evaluation every week during radiotherapy, and in the second and sixth weeks after the end of the treatment, they received physical examinations and surveys, including questionnaire surveys, skin observations and measurements. The study lasted for 3 months. Skin observation items included physiological parameters such as skin moisture, temperature, melanin, transepidermal water loss (TEWL), and clinical evaluation of skin reactions by physicians. Through statistical analysis of skin physiological parameters, scientific instruments can quantify the radiation skin reactions traditionally judged by clinical physicians by visual examination and can perform real-time clinical prediction monitoring, which can be used to establish a skin reaction prediction model in the future.
The implementation of liquid biopsy in clinical practice has been favored by the rapid development of genome sequencing techniques designed to analyze mutations in ctDNA. Among these, the Next generation sequencing (NGS) is a technique that consists in sequencing several genomes in a short time span, collecting information about a wider range of genomic alterations, using small quantities of genetic material. It is used to identify potential circulating dynamic biomarkers of treatment sensitivity or resistance in a real word multi-pathology evaluation. In this way, defining the mutational status of clinical relevance genes in real world, as a predictive biomarker to identify those patients most likely to benefit from target therapy, offers the potential to optimize access to further therapies. The aim of this study is to evaluate the real-world prevalence of clinically useful mutations in patients who are receiving therapy for advanced and locally advanced solid tumor through liquid biopsy.
Breast cancer is, in term of incidence, the first cancer among women in France and worldwide. This incidence is increasing, particularly among young women during their professional activity. Those observations raise de question of return to work of those patients, and, broadly, of the post cancer life and former activities recovery. The objective of the study is to identify any factor influencing time from diagnosis to return to work (type of treatment, side effects, residual symptoms, medical staff support, occupational physician monitoring, individual or group supportive therapy, adapted physical activity, alternative therapeutics ..), and the main modalities of return to work (part or full time, professional redeployment). To identify those factors, barriers or supports, would enable the implementation of concrete actions and programs, promoting return to work, and to a free disease life for those patients. The main objective is to identify psycho social factors involved in the time from diagnosis to return to any modality of work, until 24 month after localized breast cancer care, in Grenoble University Hospital (Michalon and Voiron included) Secondary objectives are to identify psycho social factors involved in the time from diagnosis to return to work, part time, full time, and redeployment, respectively, until 24 month after localized breast cancer care, in Grenoble University Hospital (Michalon and Voiron included)
The purpose of this study to find out whether an intensive approach to treating high blood pressure during breast cancer treatment is safe and more effective than standard blood pressure treatment at lowering blood pressure levels and the risk of cardiotoxicity in patients with cancer. Other studies have shown lowering blood pressure improves the health of patients. However, these studies have not included people with cancer. The PROTECT trial is testing a treatment strategy regarding intensive versus standard SBP goals, and is not testing specific medications.
This monocentric early feasibility first in human study is intended to evaluate safety and performance of intraoperative detection of light signals during electrosurgical breast cancer resection. In consequence the data should also be taken to adapt technical features according to the findings. The study results will be utilized to design and to calculate the sample size for future pivotal studies after finalizing this study and to adapt the technical features of the system and/ or device. In the future pivotal study, the effectiveness of method and the reduction in R1 resection rate will be assessed with the final goal to provide continuous or real-time information about the tissue type that is currently cut. The primary endpoint for this first in human feasibility study is the percentage of patients with no serious adverse event related to the investigational device. After signing the informed consent the doctor and research team will determine if the participant meets all requirements for this study. During the second visit (V2) they will receive the treatment procedure with the investigational medical device (IMD). The follow up visit (V3) will be performed up to 7 days after the treatment procedure at the day of discharge from the hospital.
The overarching goal of this project is to optimize the collection of social and behavioral determinants of health (SBDOH) for patients with a pathological diagnosis of breast cancer at Penn Medicine. The investigators will measure rates of SBDOH data collection by modality and rates of referral to and uptake of social support services, time to evaluation, staff time, acceptability, patient-centered communication, medical mistrust, and clinician acceptability.
Rhomboid intercostal block is used to block lateral cutaneous branches of intercostal nerves between T3 and T9 dermatomes. RIB has been reported to be successful in attenuating acute pain following breast surgeries. However, it's effect on chronic pain has not been evaluated yet. The primary hypothesis of the study is that the incidence of chronic pain of the patients who will receive Rhomboid intercostal block (RIB) following breast cancer surgery will be lower than the patients who will receive no block intervention at the postoperative 3rd month. The secondary hypothesis is that the incidence ofchronic pain of the patients who will receive Rhomboid intercostal block (RIB) following breast cancer surgery will be lower than the patients who will receive no block intervention at the postoperative 6th month. An other secondary hypothesis is that the total BPI-SF scores will be lower in the RIB group than control group at the postoperative 3rd and the 6th months.
The goal of this observational study is to use cfDNA multi-omics technology to explore a new breast cancer early detection model to improve the accuracy of early diagnosis in breast cancer patients. The main questions it aims to answer are: - Evaluate the sensitivity and specificity of the early detection model for breast cancer screening - Evaluate participants' TeFei™ score Participants will be collected peripheral venous blood before surgery or systemic treatment. The blood will then be sent to the collaboration company for sequencing. The collaboration company will analyze the sequencing results and build a cfDNA multi-omics signature library. Finally, the collaboration company will use deep learning algorithms to train and optimize the feature library. Researchers will compare the cancer group with a benign control group to determine the model's effectiveness in differentiating between them.
