Article Abstract
Immunoscore (IS), based on CD3/CD8, has been proposed to characterize the immune landscape of the tumor immune microenvironment and has demonstrated an association with the prognosis of laryngeal squamous cell carcinoma (LSCC). However, traditional IS does not include immunosuppressive cells. The purpose of this study is to evaluate the prognostic performance of cytotoxic-T-lymphocytes to immunosuppressive cells ratio (CIL) in laryngeal squamous cell carcinoma (LSCC) patients. Two cohorts were included in this study: The training cohort (N = 75) consisted of tumor tissue microarrays from LSCC patients in our department, and the validation cohort (N = 116) utilized bulk RNA-seq data from the TCGA database. Patients with high IS or CIL showed significantly prolonged overall survival and disease-free survival in both cohorts. Upon analyzing the relative contribution of each parameter, it was found that CIL exhibited the highest significance among the factors examined. It emerged as the strongest predictor of overall survival, emphasizing its crucial influence in determining the outcomes. The prognostic ability of IS-TCGA was similar to the original IS. Additionally, high CILM2-TCGA was associated with prolonged survival of patients with LSCC in the TCGA dataset. CIL, which is easier to construct than IS, proves to be reliable in predicting survival outcomes for patients with LSCC.

Head and neck squamous cell carcinoma (HNSCC) originates in the epithelial lining of the oral cavity, pharynx, and larynx, with over 830,000 new cases diagnosed globally in 2020, making it the seventh most prevalent cancer. Despite treatment advances, high-grade HNSCCs remain associated with poor outcomes and a high risk of recurrence. Although Cancer Stem Cells (CSCs) are rare in HNSCC tumors, they are key drivers of tumor relapses, as they evade apoptosis and survive current therapies through enhanced DNA repair and quiescence.

Current literature on LCCC is limited to case reports with little comprehensive data available. This systematic review aims to analyze existing literature to better characterize LCCC and to identify trends in presentation, treatment, and survival.

Methods: Patients with unresected LA SCCHN (oropharynx [p16-negative only], hypopharynx, or larynx) were randomly assigned 1:1 to six cycles of oral xevinapant 200 mg/day or matched placebo (once daily on Days 1-14 of a 21-day cycle) plus CRT for the first three cycles (cisplatin [100 mg/m once on Day 2 of every cycle] plus intensity-modulated radiotherapy [70 Gy; 35 fractions of 2 Gy/day, 5 days/week]). The primary end point was event-free survival (EFS) assessed by the blinded independent review committee.

Background: Postoperative complications following esophageal surgery are severe, with respiratory complications being the most common. This study aims to evaluate the rate of respiratory complications and related factors post-esophagectomy and lymph node dissection for esophageal squamous cell carcinoma (ESCC).
Subjects And Methods: A prospective cross-sectional study was conducted from October 2022 to March 2024 on ESCC who underwent minimally invasive esophagectomy and extended two-field lymph node dissection.

Background: Esophageal squamous cell carcinoma remains a major health burden in China, where surgical resection is the mainstay of curative therapy. The conventional minimally invasive McKeown esophagectomy (MIE-McKeown), although oncologically effective, entails transthoracic access and single-lung ventilation, often resulting in higher postoperative morbidity. Thoraco-laparoscopic transmediastinal esophagectomy has emerged as a novel alternative that may mitigate these risks while preserving oncologic integrity.
