Article Abstract
Objectives: Surgery has traditionally been the treatment of choice for patients with potentially resectable esophageal carcinoma. Recently, however, definitive chemoradiotherapy (CRT) has been suggested as a preferred treatment modality. In this study, CRT results with or without surgery are compared.
Methods: A total of 986 patients of esophageal carcinoma were categorized into two groups depending on the treatment: surgery (675 patients) or CRT (311 patients). These two groups were compared based on age, sex, weight loss, tumor location and length, tumor shape, grade, stage, delay in receiving treatment, event-free survival (EFS) and overall survival (OS).
Results: Patients in the CRT arm were significantly older (p = 0.01), had a more significant adenocarcinoma histology (p = 0.015), upper esophageal carcinoma (p = 0.0001) and more advanced stages of the disease (p = 0.0001). The median EFS for the surgery group was 24.5 months [95% confidence interval (CI), 17-32] versus 22.5 months (95% CI, 16.7-28.2) for the CRT arm (p = 0.56). The mean OS was 59.25 months (95% CI, 53.8-64.7) for the surgery group compared to 58.77 months (95% CI, 50.9-66.6) for the CRT group (p = 0.78).
Conclusion: Definitive CRT is effective enough so as to consider omitting surgery and could be used as a standard treatment for patients with esophageal carcinoma.

Department of Oncology, Nanjing Drum Tower Hospital Clinical College of Nanjing University of Chinese Medicine, Nanjing, 210008, Jiangsu, China.
This study aims to investigate the expression of seven cancer testis antigens (MAGE-A1, MAGE-A4, MAGE-A10, MAGE-A11, PRAME, NY-ESO-1 and KK-LC-1) in pan squamous cell carcinoma and their prognostic value, thus assessing the potential of these CTAs as immunotherapeutic targets. The protein expression of these CTAs was evaluated by immunohistochemistry in 60 lung squamous cell carcinoma (LUSC), 62 esophageal squamous cell carcinoma (ESCA) and 62 head and neck squamous cell carcinoma (HNSC). The relationship between CTAs expression and progression-free survival (PFS) was assessed.

Introduction: A precise preoperative tumor monitoring method that reflects tumor burden during neoadjuvant treatment is required to guide individualized perioperative treatment strategies for esophageal squamous cell carcinoma (ESCC). This study examined the clinical significance of preoperative circulating tumor DNA (ctDNA) in the plasma of patients undergoing neoadjuvant chemotherapy (NAC) followed by esophagectomy.
Materials And Methods: Plasma samples were collected longitudinally for ctDNA analysis as well as genomic DNA from primary lesions from patients with histologically confirmed ESCC who received neoadjuvant chemotherapy (NAC) followed by subtotal esophagectomy.

Background: The purpose of this study was to investigate the safety and efficacy of left thoracic approach (LTA) and right thoracic approach (RTA) in patients with esophageal squamous cell carcinoma (ESCC) after neoadjuvant immunochemotherapy (NICT).
Methods: This study included 83 ESCC patients who underwent right transthoracic esophagectomy ( = 61) and left transthoracic esophagectomy ( = 22) after NICT in our hospital from October 2019 to September 2023. The data of these patients were retrospectively analyzed.

Department of Cardiothoracic Surgery, The Affiliated Jiangyin Hospital of Nantong University, 214400 Jiangyin, Jiangsu, China.
Background: This study investigates the role of small ubiquitin-like modifier (SUMO)-specific peptidase 5 (SENP5), a key regulator of SUMOylation, in esophageal squamous cell carcinoma (ESCC), a lethal disease, and its underlying molecular mechanisms.
Methods: Differentially expressed genes between ESCC mouse oesophageal cancer tissues and normal tissues were analysed via RNA-seq; among them, SENP5 expression was upregulated, and this gene was selected for further analysis. Immunohistochemistry and western blotting were then used to validate the increased protein level of SENP5 in both mouse and human ESCC samples.

The management of esophageal cancer (EC) remains a significant clinical challenge, particularly in optimizing therapeutic strategies for different stages and subgroups. This study assessed the impact of preoperative radiochemotherapy (CRT) on clinical staging and identified subgroups for whom definitive CRT (dCRT) may provide a favorable alternative to surgery. Sixty-one patients with esophageal adenocarcinoma or squamous cell carcinoma were enrolled.
