Local treatment improves the outcomes for oligometastatic disease, an intermediate state between locoregional and widespread disease. However, consensus about the definition, diagnosis and treatment of oligometastatic oesophagogastric cancer is lacking. The first edition "Definition, diagnosis and treatment of oligometastatic oesophagogastric cancer: A Delphi consensus study in Europe" was published on February 15, 2023 by 65 European medical specialists. In this article, the consensus will be interpreted to provide new idea for the diagnosis and treatment of oligometastatic oesophagogastric cancer for Chinese clinicians.
Surgical resection is the only radical method for the treatment of early-stage non-small cell lung cancer. Intraoperative frozen section (FS) has the advantages of high accuracy, wide applicability, few complications and real-time diagnosis of pulmonary nodules. It is one of the main means to guide surgical strategies for pulmonary nodules. Therefore, we searched PubMed, Web of Science, CNKI, Wanfang and other databases for nearly 30 years of relevant literature and research data, held 3 conferences, and formulated this consensus by using the Delphi method. A total of 6 consensus contents were proposed: (1) Rapid intraoperative FS diagnosis of benign and malignant diseases; (2) Diagnosis of lung cancer types including adenocarcinoma, squamous cell carcinoma, others, etc; (3) Diagnosis of lung adenocarcinoma infiltration degree; (4) Histological subtype diagnosis of invasive adenocarcinoma; (5) The treatment strategy of lung adenocarcinoma with inconsistent diagnosis on degree of invasion between intraoperative FS and postoperative paraffin diagnosis; (6) Intraoperative FS diagnosis of tumor spread through air space, visceral pleural invasion and lymphovascular invasion. Finally, we gave 11 recommendations in the above 6 consensus contents to provide a reference for diagnosis of pulmonary nodules and guiding surgical decision-making for peripheral non-small cell lung cancer using FS, and to further improve the level of individualized and precise diagnosis and treatment of early-stage lung cancer.

If one word is used to describe the development of congenital heart disease surgery in China, "hardship" would be the most appropriate. Generations of pioneers have used their ingenuity to overcome obstacles and promoted the development of the discipline. Seventy years of efforts have established the world's largest congenital heart disease treatment system. However, the huge number of potential patients, low early diagnosis rate and over-screening as well as the uneven developed diagnosis and treatment capabilities hinder the future development. The overall improvement of treatment of congenital heart disease in China lies on more efforts from our fellow experts. The publication of the "Chinese expert consensus on surgical treatment of congenital heart diseases" undoubtedly provides theoretical and practical guidance for the improvement of treatment.
With the advancement of research on rare ocular diseases such as inherited retinal dystrophy (IRD) has advanced in recent years, especially breakthroughs in therapeutic approaches represented by cell and gene therapy, potential intervention strategies have emerged for these conditions. Establishing standardized endpoints and evaluation methods for visual function in patients with IRD has become crucial for assessing disease progression, safety, and therapeutic efficacy of innovative treatments. Best corrected visual acuity (BCVA) is widely recognized as one of the primary endpoints for assessing visual function. However, for IRD patients with severe rod photoreceptor dysfunction, who often present with profound low vision or even legal blindness, the applicability of BCVA as a traditional visual function indicator is limited. The multi-luminance mobility test (MLMT) has emerged as a functional visual assessment tool that evaluates the ability to navigate obstacle courses under varying illumination levels. By establishing graded evaluation standards, MLMT objectively quantifies the impact of lighting conditions on patients’ nobility and spatial orientation, providing a novel quantitative tool for assessing visual function in IRD clinical trials. Currently, there is a lack of unified and standardized guidelines for the use of MLMT in China, posing challenges to its implementation in practical clinical research. To address this, Ocular Fundus Disease Society of Chinese Medical Association and Chinese Medical Doctor Association convened a multidisciplinary team comprising clinical experts in genetic retinal diseases, statisticians, and optical specialists to investigate the current applications and technical characteristics of MLMT, ultimately formulating consensus recommendations for its use as a clinical trial endpoint for IRD gene therapies. This consensus aims to provide a set of MLMT operating norms applicable to China's national conditions, guide clinical practice and research in ophthalmology and related disciplines, and promote the standardization process of IRD clinical trials in China, so as to better serve the IRD patient population and promote the development of related fields.
Neurofibromatosis type 1 (NF1) is an autosomal dominant neoplastic disease caused by mutations in the NF1 gene and one of the most challenging diseases to treat. Patients have a characteristic phenotype with neurofibromas as the main features in different forms, including numerous cutaneous neurofibromas, plexiform neurofibromas involving the primary nerves, or malignant peripheral nerve sheath tumors with a very short survival period after malignant transformation. NF1 patients also suffer from multi-system involvement, with a high rate of deformity and disability, making complete surgical resection more difficult. Currently, there is no consensus on the diagnosis and treatment of NF1 in China, and different disciplines have different understandings of NF1. Multidisciplinary systematic evaluations and cooperative treatments are the keys to improve the treatment, quality of life, and prognosis of NF1 patients. In 2020, the Department of Plastic Surgery of the Ninth People’s Hospital of Shanghai Jiaotong University School of Medicine led the establishment of the first multi-center collaboration group for NF1 in China. Furthermore, the group had worked with renowned experts from the various departments including surgical oncology, medical oncology, dermatology, reproductive medicine, et al. in China to formulate the “Expert consensus on diagnosis and management of neurofibromatosis type 1 (2021 edition)”, aiming to promote standardized and homogeneous treatment covering the whole life cycle of NF1 patients and improve the treatment level and outcome of NF1 patients in China.
In order to further improve the treatment level of rib, sternum, and lung trauma in China, and to provide patients with a comprehensive, safe, scientific, and standardized treatment model, we convened a meeting of outstanding thoracic surgery experts in the field of trauma in China to demonstrate and solicit opinions widely, and in accordance with the principle of evidence-based medicine, based on the best published Chinese and English evidence, finally formulated this consensus. This consensus aims to solve the possible problems in the treatment of lung, rib, and sternum trauma to the greatest extent, and provide scientific and standard clinical solutions for the treatment of thoracic surgery trauma.
Previous studies have shown that rehabilitation can relieve clinical symptoms, prevent complications, and improve physical function and quality of life in patients with pneumonia. This consensus summarizes the rehabilitation assessment, self-protection, rehabilitation goals, rehabilitation programs, indications for termination of treatment, nutrition support and psychological rehabilitation for patients with mild, moderate, severe and critical types of coronavirus disease 2019 based on the relevant literature and previous practice of coronavirus disease 2019. We hope this consensus can provide a reference for rehabilitation of coronavirus disease 2019.
With the widespread adoption of low-dose CT screening and the extensive application of high-resolution CT, the detection rate of sub-centimeter lung nodules has significantly increased. How to scientifically manage these nodules while avoiding overtreatment and diagnostic delays has become an important clinical issue. Among them, lung nodules with a consolidation tumor ratio less than 0.25, dominated by ground-glass shadows, are particularly worthy of attention. The therapeutic challenge for this group is how to achieve precise and complete resection of nodules during surgery while maximizing the preservation of the patient's lung function. The "watershed topography map" is a new technology based on big data and artificial intelligence algorithms. This method uses Dicom data from conventional dose CT scans, combined with microscopic (22-24 levels) capillary network anatomical watershed features, to generate high-precision simulated natural segmentation planes of lung sub-segments through specific textures and forms. This technology forms fluorescent watershed boundaries on the lung surface, which highly fit the actual lung anatomical structure. By analyzing the adjacent relationship between the nodule and the watershed boundary, real-time, visually accurate positioning of the nodule can be achieved. This innovative technology provides a new solution for the intraoperative positioning and resection of lung nodules. This consensus was led by four major domestic societies, jointly with expert teams in related fields, oriented to clinical practical needs, referring to domestic and foreign guidelines and consensus, and finally formed after multiple rounds of consultation, discussion, and voting. The main content covers the theoretical basis of the "watershed topography map" technology, indications, operation procedures, surgical planning details, and postoperative evaluation standards, aiming to provide scientific guidance and exploration directions for clinical peers who are currently or plan to carry out lung nodule resection using the fluorescent microscope watershed analysis method.
ObjectiveTo assess the efficacy of lymphadenectomy in different regions for esophageal squamous cell carcinomas located differently according to the lymph node grouping by Chinese expert consensus. MethodsThe medical records of 1 061 patients (886 males and 175 females with a median age of 60 (54, 65) years with esophageal cancer from March 2011 to December 2017 in our hospital were retrospectively analyzed. According to the pathological report, the lymph nodes were regrouped according to the Chinese lymph nodes grouping standard of esophageal cancer. The metastasis rate of each group of lymph nodes, the 5-year survival rate of metastatic patients and efficacy index (EI) were calculated. ResultsThe upper thoracic esophageal cancer mainly metastasized to the lymph nodes of C201-203 groups. The middle and lower thoracic tumors mainly metastasized to the lymph nodes of C205-207 groups. The lower thoracic tumor had a higher rate of metastasis to the abdominal lymph nodes. According to the metastasis rate, the mediastinal lymph nodes were divided into three regions: an upper mediastinum (C201-204), a middle mediastinum (C205-206), and a lower mediastinum (C207-209). The EIs of lymph nodes of C201-203 and C205-207 groups were higher. For patients with C201-207 groups metastasis, the 5-year survival rates ranged from 13.39% to 21.60%. For patients with positive lymph nodes in each region, tumors at different primary locations had no statistical difference in long-term survival (P>0.05). Patients with lymph nodes of C205 group in the upper thoracic tumors had lower EI and those in the middle and lower thoracic tumors had higher EIs. ConclusionThe effect of lymph node dissection in each area varies with the location of the tumor. No matter where the tumor is, it is necessary to dissect the upper mediastinal lymph nodes, especially the lymph nodes adjacent to the left and right recurrent laryngeal nerves. Group C205 should be classified into the lower mediastinal lymph nodes.
