Background: The 7th edition American Joint Committee on Cancer tumor-node-metastasis (AJCC TNM) staging system was published in 2010. Here we evaluate its predictive ability and compare the 6th and 7th editions of the AJCC TNM staging systems in esophageal squamous cell cancer (ESCC) with preoperative radiotherapy.
Methods: A total of 296 esophageal squamous cell carcinoma patients receiving preoperative radiotherapy between 1980 and 2007 were included. Patients were staged using the 6th and 7th edition staging systems. Survival analyses were performed using Cox regression models. The homogeneity, discriminatory ability, and monotonicity of gradients of the two staging systems were compared using linear trend χ(2), likelihood ratio statistics, and Akaike information criterion calculation.
Results: The overall five-year survival rate for the entire cohort was 27.1%. Female gender, length, "T," and "N," classifications according to the 7th edition staging system were the prognostic factors in univariate analyses. However, tumor histological grade and cancer location did not significantly influence patient survival. The 7th edition staging system has the highest linear trend χ(2)and likelihood ratio χ(2)scores. Compared to the 6th edition, the 7th edition staging system also has a smaller Akaike information criterion value, which represents the optimum prognostic stratification.
Conclusions: The strength of the 7th edition AJCC TNM staging system lies in the new descriptors for "T" and "N" classifications. However, we did not find cancer location to be a significant prognostic factor in our cohort. Overall, the 7th edition AJCC TNM staging system performed better than the previous edition.

Background: The definition of T1b cutaneous melanoma was changed in the 8th edition of the AJCC staging system based on survival differences but not risk of sentinel lymph node (SLN) metastases. We sought to evaluate changes in SLN biopsy (SLNB) use and rates of positive SLNB in response to updated staging criteria, and to evaluate the incidence of high-risk features in T1a melanoma in whom SLNB is now recommended.
Study Design: The 2021 National Cancer Database Melanoma PUF was used to obtain SLNB utilization and positivity rates in T1 (thin) melanoma (thickness ≤1.

The Canadian Stroke Best Practice Recommendations (CSPR) 7th edition includes this new module on the diagnosis and management of vascular cognitive impairment (VCI) with or without neurodegenerative disease. An expert writing group and people with VCI lived experience (PWLE) reviewed current evidence. Existing recommendations were reviewed and revised, and new recommendations added.

Over the last decade, the annual Immunorad Conference, held under the joint auspicies of Gustave Roussy (Villejuif, France) and the Weill Cornell Medical College (New-York, USA) has aimed at exploring the latest advancements in the fields of tumor immunology and radiotherapy-immunotherapy combinations for the treatment of cancer. Gathering medical oncologists, radiation oncologists, physicians and researchers with esteemed expertise in these fields, the Immunorad Conference bridges the gap between preclinical outcomes and clinical opportunities. Thus, it paves a promising way toward optimizing radiotherapy-immunotherapy combinations and, from a broader perspective, improving therapeutic strategies for patients with cancer.

In December 2023, the Trauma Professional Committee of the American Society of Surgeons officially released the seventh edition of "Resources for Optimal Care of the Injured Patient (2022 Stan-dards)". Compared to the sixth edition of the standards, the main updated content of the seventh edition includes ten aspects: (1) trauma centers need to meet new personnel configuration and qualification requirements, (2) trauma centers need to develop more structured and effective trauma treatment effectiveness improvement and patient safety plans, (3) trauma centers need to develop data quality plans, (4) trauma centers need to develop new diagnosis and treatment plans for specific patients, (5) trauma centers need to have new professional knowledge, (6) trauma centers need to meet new response time and resource availability standards, (7) trauma centers need to meet new academic and scientific requirements, (8) tertiary trauma centers need corresponding qualification certificates if providing neurological trauma treatment, (9) new requirements for pediatric trauma centers, (10) the fourth level trauma center standards. The research literature published by scholars in the field of trauma in the past decade has provided sufficient evidence-based medicine evidence for updating content.
