The cancer staging system of the American Joint Committee on Cancer (AJCC) is the most widely used clinical basis for tumor staging. In October 2023, AJCC released the staging system (ninth version) for the neuroendocrine tumors of stomach (NET), which has been implemented in January 2024. The ninth version of NET staging system mainly updated the histopathologic classification, diagnosis and staging methods, clinical and pathological staging, prognosis grade, tumor and non-tumor prognostic features. The update and implementation of the staging system provide a more detailed reference for the accurate diagnosis, staging and precise treatment of gastric neuroendocrine tumors. Moreover, it is convenient for clinicians to carry out clinical practice. The purpose of our article is to provide a high-level overview of the major changes in AJCC staging system (version 9) for gastric NET based on the latest evidence-based medical research.

High-throughput sequencing has the characteristics of complex experimental procedures, multiple quality control nodes, and a high proportion of bioinformatics technology. It is difficult to uniformly management and reuse the related detection samples and data. In May 2023, a tertiary hospital launched the construction of a localized high-throughput sequencing management system. Based on the design principles of security, friendliness, compatibility, and scalability, the management system had established three core modules: standardized data collection integration, clinical high-throughput sequencing full process management, and scientific research services, as well as a large clinical high-throughput sequencing database of hospital. By connecting with big data storage devices, local and third-party high-throughput sequencing detection platforms, sample libraries, and user terminals, this system broke down the data barriers of high-throughput sequencing related systems and devices, and met the different application scenarios of physician users, technician users, management users, and scientific research users in the hospital. As of October 2023, the system had been integrated with two high-throughput sequencing manufacturer devices in a public network environment and hospital information systems in an internal network environment, improving data retrieval efficiency and achieving closed-loop management of high-throughput sequencing detection projects preliminary, which can provided references for promoting the standardized management of high-throughput sequencing projects in hospitals in China.
