Clinical study of breast cancer

Clinical research on breast cancer refers to scientific research on the diagnosis, treatment and prevention of breast cancer. These studies are aimed at improving the treatment of breast cancer, reducing mortality and improving the quality of life of patients. i. Research directed towards the development of new breast cancer screening methods for early diagnosis to improve early detection rates. For example, new video technology (e.g. mammography, mammography, mammography, etc.) and biomarkers (e.g. tumour markers in blood, gene expression spectrum in breast tissue, etc.) have been studied to improve early detection accuracy of breast cancer. Explore methods of diagnosis of breast cancer based on artificial intelligence and machine learning to improve the efficiency and accuracy of diagnosis through the analysis of a large number of medical images and clinical data. Development of new drugs for treatment: development of new drugs for specific molecular targets for breast cancer, such as target treatment drugs, immunotherapy drugs, etc. Study the efficacy, safety and resistance of drugs and optimize treatment programmes. Joint treatment strategy: explore joint applications of different treatments, such as combinations of chemotherapy and target-to-target treatments, and combinations of therapeutic and immunotherapy treatments, to improve treatment effectiveness and reduce side effects. Individualized treatment: the development of individualized treatment programmes based on the tumour molecular characteristics of the patient, gene expression spectrum, immunisation status, etc., to increase the responsiveness and effectiveness of treatment. Post-pregnostic assessment studies on pre-postfactors for breast cancer patients, such as tumour size, lymphoma knots, molecular spectrometry, gene expression, etc., and the development of pre-post-evaluation models to provide patients with more accurate pre-pregnosis information. Explore new prophylactic biomarkers, such as circulatory tumour cells, circulatory tumours, DNA, etc., to predict re-emergence risks and therapeutic responses at an early stage. The prevention strategy examines risk factors for breast cancer, such as genetic factors, lifestyle factors (e.g. diet, exercise, smoking, alcohol, etc.), environmental factors, etc., and develops appropriate prevention strategies. Clinical trials for breast cancer prevention, such as chemical prevention (the use of drugs to prevent the occurrence of breast cancer), lifestyle interventions, etc., assess the effectiveness and safety of preventive measures. Second, clinical trials of research methods are one of the most commonly used methods in the clinical study of breast cancer. Clinical trials are human studies aimed at assessing the safety and effectiveness of new treatments, drugs or diagnostic techniques. Clinical trials usually have different stages, including I, II, III and IV. Phase I clinical trials primarily assess the safety and dose range of new drugs or treatments; Phase II clinical trials further assess the efficacy and safety of drugs or treatments; Phase III clinical trials are large-scale random control trials, comparing the efficacy and safety of new treatments with standard treatments; Phase IV clinical trials are conducted after drugs or treatments are listed and primarily assess their long-term efficacy and safety. Observatory research is to observe and analyse the clinical characteristics, treatment effects and prognosis of patients without interfering with their treatment. Observational studies include queue studies, case comparison studies and cross-section studies. The Queue Study is a long-term follow-up visit to a group of people to observe their risk of breast cancer and the effects of treatment. Case comparison studies compare the clinical characteristics and risk factors of patients with and without breast cancer. Cross-section studies are conducted at a specific point in time for a group of people to learn about the incidence of breast cancer and related factors. Basic research is carried out in laboratories to explore mechanisms for the incidence of breast cancer, biological behaviour and targets for treatment. Basic studies include cell biology, molecular biology, animal experiments, etc. cytological research focuses on biological behaviour such as breast cancer cell growth, breeding, death, transfer, and the mechanism of drug effects on breast cancer cell. Molecular biology studies focus on the expression, mutation, regulation, etc. of genes associated with breast cancer, and the feasibility of gene therapy. Animal experiments are studies on animal models to assess the safety and effectiveness of new treatments or drugs. The significance of engaging in clinical research is that new treatment opportunities are available to patients: patients involved in clinical research may have access to the latest treatment methods or drugs, which may be more effective than standard treatment. Closer medical attention: Patients involved in clinical research usually receive closer medical attention and monitoring, including regular physical, laboratory and visual examinations. Contributing to medical progress: Patients involved in clinical research can contribute to medical progress by helping researchers to better understand the treatment of breast cancer and pre- and post-factors and provide better treatment options for future patients. For medical research to promote medical progress: Clinical research is one of the most important means of promoting medical progress. Through clinical research, researchers can continuously explore new treatment methods and diagnostic techniques to improve the efficacy and survival of breast cancer. Optimizing treatment programmes: Clinical research compares the efficacy and safety of different treatments and provides patients with better treatment options. Improving the quality of care: Clinical research can contribute to the improvement of the quality of care and ensure the reliability and effectiveness of research results through standardized research design and rigorous quality control.
