As one of the most breakthrough cutting-edge technologies in the biomedical field in recent years, organoid culture technology can use cells derived from, either (pluripotent) stem cells or tissue-derived differentiated/progenitor cells (foetal, neonatal, or adult) to form 3D multicellular structure organoids with self-organizing and recapitulating at least some features of the organ including tissue architecture or function abilities. Recently, organoids have been widely used in disease model construction, anti-cancer drug screening, gene or cell therapy, etc., providing an ideal model for basic biomedical research, drug development and clinical precision medicine, and has shown an important role in regenerative medicine.
Precision medicine is a personalized medical system based on patients' individual biological information, clinical symptoms and signs, forming a new clinical research model and medical practice path. The basic idea of traditional Chinese medicine and the concept of precision medicine share many similarities. The basket trial developed for precision medicine is also suitable for clinical trials and evaluation of the efficacy of traditional Chinese medicine syndrome differentiation and treatment systems. Basket trials are used to evaluate the efficacy of a drug in the treatment of multiple diseases or disease subtypes. It has the advantages of sharing a master protocol, unifying management of subsidiary studies, simplifying the test implementation process, unifying statistical analysis, saving resources, reducing budgets and accelerating the drug evaluation progress. This is similar to the concept of using the "same treatment for different diseases" found in traditional Chinese medicine. This paper introduced the concept and method of basket trials and explored their application and advantages in clinical research into traditional Chinese medicine. This study is expected to provide references for the methodological innovation of clinical research into traditional Chinese medicine.
Precision medicine is a medical paradigm founded on individual genetic information amalgamated with extensive clinical data to offer patients precise diagnoses and treatments. Genetic testing forms the cornerstone of accurate diagnosis, and skilled professionals in fields like clinical medicine, molecular biology, and bioinformatics play a crucial role in realizing the potential of precision medicine. This paper presents reference suggestions for the continuing education approach for relevant technical personnel. The main emphasis is on conducting routine face-to-face and hands-on training to enhance theoretical knowledge and professional skills. Secondly, there is a need to modify the training approach by reinforcing molecular biology, bioinformatics, and other courses, enhancing assessment methods, gradually implementing specialized training in precision medicine subspecialties, and ensuring effective clinical practice and management of precision medicine.
Breast cancer is one of the most common malignant tumors among women. Typically, the operation of breast cancer should include breast surgery and axillary lymph node surgery since breast cancer first metastasizes to regional axillary lymph nodes. However, postoperative breast cancer-related lymphedema (BCRL) in upper limb is the most common long-term complication. The injury to upper limb lymphatic system contributes to causing the postoperative BCRL. Therefore, precision medicine in the extent of axillary lymph node surgery plays an important role in preventing BCRL which can improve the quality of life in breast cancer patients.
Along with the popularity of low-dose computed tomography lung cancer screening, an increasing number of early-stage lung cancers are detected. Radical lobectomy with systematic nodal dissection (SND) remains the standard-of-care for operable lung cancer patients. However, whether SND should be performed on non-metastatic lymph nodes remains controversy. Unnecessary lymph node dissection can increase the difficulty of surgery while also causing additional surgical damage. In addition, non-metastatic lymph nodes have been recently reported to play a key role in immunotherapy. How to reduce the surgical damage of mediastinal lymph node dissection for early-stage lung cancer patients is pivotal for modern concept of "minimally invasive surgery for lung cancer 3.0". The selective mediastinal lymph node dissection strategy aims to dissect lymph nodes with tumor metastasis while preserving normal mediastinal lymph nodes. Previous studies have shown that combination of specific tumor segment site, radiology and intraoperative frozen pathology characteristics can accurately predict the pattern of mediastinal lymph node metastasis. The personalized selective mediastinal lymph node dissection strategy formed from this has been successfully validated in a recent prospective clinical trial, providing an important basis for early-stage lung cancer patients to receive more personalized selective lymph node dissection with "precision surgery" strategies.
Lung cancer is one of the leading causes of cancer deaths worldwide. Many options including surgery, radiotherapy, chemotherapy, targeted therapy and immunotherapy have been applied in the treatment for lung cancer patients. However, how to develop individualized treatment plans for patients and accurately determine the prognosis of patients is still a very difficult clinical problem. In recent years, radiomics, as an emerging method for medical image analysis, has gradually received the attention from researchers. It is based on the assumption that medical images contain a vast amount of biological information about patients that is difficult to identify with naked eyes but can be accessed by computer. One of the most common uses of radiomics is the diagnosis and treatment of non-small cell lung cancer (NSCLC). In this review, we reviewed the current researches on chest CT-based radiomics in the diagnosis and treatment of NSCLC and provided a brief summary of the current state of research in this field, covering various aspects of qualitative diagnosis, efficacy prediction, and prognostic analysis of lung cancer. We also briefly described the main current technical limitations of this technology with the aim of gaining a broader understanding of its potential role in the diagnosis and treatment of NSCLC and advancing its development as a tool for individualized management of NSCLC patients.
Liddle syndrome and Gordon syndrome are two rare single-gene inherited hypertension diseases. In patients≤40 years, the prevalence of Liddle syndrome is about 1% and Gordon syndrome is uncertain all over the word, for which is often misdiagnosed and mistreated. The therapies of those diseases are targeted at gene mutation sites, as well as combined with modified lifestyle, and can achieve satisfactory diseases control. This paper reports a patient who is diagnosed with Liddle syndrome and Gordon syndrome at the same time. We aimed to consolidate and improve the diagnosis and accurate treatment of those two diseases by sharing, studying and discussing together with clinical doctors.
Precision medicine is an individualized clinical research model established according to gene, environment, lifestyle and other information. As an innovative method of clinical trials, the main scheme design breaks the barriers of traditional randomized controlled trials to the evaluation of targeted therapies in precision medicine and improves the efficiency of clinical research. This paper will systematically introduce the types, concepts and principles of the main scheme design of the new method of precision medicine clinical trial design, and summarize the advantages and limitations of the main scheme design combined with classic cases, aiming at providing scientific and rigorous methodological guidance and clinical practice experience for precision medicine scientific research design.
Abstract Precision medicine is an ideal medical paradigm which combines modern scientific methods with traditional medical methods to diagnose, treat and evaluate the physical function and nature of diseases more precisely, and to maximize health benefits and minimize the risk of individuals and society with the most effective, safest, and the most economical medical service. Evidence-based medicine is necessary to verify the precision of diagnosis and treatment. In this review, we clarified the conception of precision medicine and the relation between precision medicine and evidence-based medicine. Moreover, we reviewed the application of precision medicine in the field of cerebrovascular disease. We pointed out that such new technologies as genetics, bioinformatics, molecular imaging and management provided tools to realize the idea of precision medicine, and high-quality evidence-based studies provided a guarantee for the clinical practice of precision medicine. In summary, precision medicine is an individualized medical mode that based on the context of a patient's genetic information, living environment and clinical data, etc. to provide precise treatment strategies for the prevention and treatment of disease, but still the promotion of precision medicine should be based on clinical validation under the guidance of evidence-based medicine. Thus, long-term exploration and unremitting efforts are required to achieve the idea of precision medicine.
