Background: Genome instability (GI) is a hallmark of esophageal squamous cell carcinoma (ESCC) while factors affecting GI remain unclear.

Methods: Here, we aimed to characterize genomic events representing specific mechanisms of GI based on 201 ESCC samples and validated our findings at the patient, single-cell and cancer cell-line levels, including a newly generated multi-omics dataset of the trial NCT04006041.

Results: A two-gene (AHNAK and AHNAK2) mutation signature was identified to define the "AHNAK1/2-mutant" cancer subtype.

Article Synopsis
  • * Whole-exome sequencing of 51 ESCC tumors before and after NCRT showed two patient groups: 13 had all pre-treatment clones disappear (clonal extinction) while 9 retained some (clonal persistence), affecting their prognosis.
  • * Clone-extinct patients had more immune activity and better T cell interactions post-NCRT, while clone-persistent patients had a higher diversity of genomic mutations but worse overall outcomes.

Background: With the popularization of low-dose spiral computed tomography (CT), an increasing number of stage IA lung cancers have been discovered. Patients with stage IA lung adenocarcinoma who undergo radical surgical resection tend to have a favourable prognosis. However, A significant proportion of patients undergo postoperative recurrence and metastasis.

  • Electromagnetic navigation bronchoscopy (ENB) is effective for diagnosing peripheral pulmonary nodules (PPNs) under 2 cm in size, but its diagnostic yield varies by specific nodule size categories.
  • In a study of 82 lesions, the overall sensitivity was 53.3%, and specificity was quite high at 91.7%, indicating that while specific, the sensitivity is lower for smaller nodules.
  • Factors like the location of the nodules did not significantly affect ENB's diagnostic accuracy, but the presence of a spiculated sign lowered the biopsy's accuracy.

Background: The study aimed to evaluate the efficacy of using near-infrared fluorescent imaging (NIRF) imaging with indocyanine green as an intraoperative tool for achieving complete mediastinal lymph node (LN) resection.

Patients And Methods: Between September 2019 and July 2021, patients with potential for esophagectomy due to middle and lower thoracic esophageal cancer were enrolled in this study. All patients were scheduled for NIRF-guided mediastinal lymphadenectomy during esophageal cancer surgery and were appropriately assigned to the NIRF group.

Article Synopsis
  • Advanced esophageal squamous cell carcinoma (ESCC) is a common and aggressive cancer, and a study showed that combining the drug tislelizumab with chemotherapy improves survival rates for these patients.
  • A Markov model was used to evaluate the cost-effectiveness of this treatment in China, finding that tislelizumab plus chemotherapy has an incremental cost-effectiveness ratio (ICER) of US$18,846 per quality-adjusted life-year (QALY), which is below the willingness-to-pay (WTP) threshold of US$38,223.
  • The study concludes that while this combination treatment is more effective than chemotherapy alone and worth the higher cost, it remains financially feasible within China's healthcare system based on the current

Purpose: We aimed to perform serial quality-of-life (QoL) evaluations and comparisons in patients after esophagectomy with intrathoracic anastomosis (IA) or cervical anastomosis (CA).

Methods: Between November 2012 and March 2015, patients who underwent esophagectomy with IA or CA for mid-esophageal to distal esophageal or gastroesophageal junction cancer were followed up. QoL was measured using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (EORTC QLQ-C30) and esophagus-specific questionnaire (EORTC QLQ-OES18) before surgery, at discharge, and at 1, 6, 12, and 24 months after discharge.

Background: Neoadjuvant chemoradiotherapy (neoCRT) followed by surgery is the most common approach for locally advanced resectable esophageal squamous cell carcinoma (ESCC) patients. How neoCRT impacts ESCC tumor immune microenvironment (TIME) has not been fully understood.

Methods: Single-cell RNA sequencing (scRNA-seq) was conducted to examine the neoCRT-driven cellular and molecular dynamics in 8 pre- and 7 post-neoCRT ESCC samples from 8 male patients.

Neoadjuvant chemoradiotherapy (NCRT) followed by surgery is recommended for locally advanced esophageal squamous cell carcinoma (ESCC) treatment. Patients who achieve a pathological complete response (pCR) have better survival. Our study aimed to discover immune-associated predictors of pCR in ESCC.

Background: Neoadjuvant chemoradiotherapy followed by esophagectomy is the standard treatment for patients with locally advanced esophageal squamous cell carcinoma (ESCC). This study explored correlations of clinical factors and dose-volume histogram (DVH) parameters with postoperative cardiopulmonary complications and predicted their risk by establishing a nomogram model.

Methods: Clinical and DVH parameters of ESCC patients who underwent trimodality treatment from 2002 to 2020 were collected.

Esophageal squamous cell carcinoma (ESCC) is one of the most life- and health-threatening malignant diseases worldwide, especially in China. Long noncoding RNAs (lncRNAs) have emerged as important regulators of tumorigenesis and tumor progression. However, the roles and mechanisms of lncRNAs in ESCC require further exploration.

Purpose: To determine risk factors, treatment outcomes, and prognostic factors for esophageal fistula (EF) in patients with esophageal squamous cell carcinoma (ESCC) during radiotherapy.

Methods: Between 2010 and 2018, 109 patients with EF during radiotherapy were retrospectively collected. A controlled cohort including 416 patients who received definitive chemoradiotherapy without EF was used to compare risk factors and survival outcomes.

Objective: To evaluate the outcome following the strategy of endoscopic R0 resection (ER) plus adjuvant treatment (AT) versus esophagectomy for esophageal squamous cell cancer in T1a invading muscularis mucosa (M3)-T1b stage.

Methods: We evaluated the outcomes of 46 esophageal squamous cell cancer (ESCC) patients with T1aM3-T1b stage who underwent ER + AT from the Esophageal Cancer Endoscopic Therapy Consortium (ECETC) and compared these outcomes to 92 patients who underwent esophagectomy. Propensity score matching (1:2) was used, with overall survival (OS) and relapse-free survival (RFS) being compared between the two groups.

Background: Glutathione S-transferase mu 3 (GSTM3) plays a crucial role in tumor progression in various cancers. However, the relationship between GSTM3 expression and the clinical prognosis of esophageal squamous cell carcinoma (ESCC) has not been studied to date. We aimed to characterize the role of GSTM3 in predicting postoperative prognosis of ESCC patients.

Background: Esophagectomy is a pivotal curative modality for localized esophageal or esophagogastric junction cancer (EC or EJC). Postoperative anastomotic leakage (AL) remains problematic. The use of fibrin sealant (FS) may improve the strength of esophageal anastomosis and reduce the incidence of AL.

Background: It is a great challenge for surgeons to resect pulmonary nodules with small volume, deep position and no solid components under video-assisted thoracoscopic surgery. The purpose of this study is to explore the feasibility and necessity of the localization of pulmonary nodules by injecting indocyanine green (ICG) under the guidance of magnetic navigation bronchoscope and the resection of small pulmonary nodules under the fluoroscope.

Methods: Between December 2018 and August 2019, sixteen consecutive patients with 30 peripheral lung lesions in our hospital received fluorescent thoracoscopic pulmonary nodule resection.

Background: Over-expression of inhibitor of differentiation or DNA binding 1 (Id-1) is associated with poor prognosis in esophageal squamous cell carcinoma (ESCC). However, some biomarkers discordant expression in metastasis has been reported previously. We aimed to confirm possible differential expression and prognostic value of Id-1 in paired metastatic lymph node (PMLN).
