Omentum preservation versus complete omentectomy in gastrectomy for gastric cancer (OMEGA trial): study protocol for a randomized controlled trial.

Background: Potentially curative therapy for locally advanced gastric cancer consists of gastrectomy, usually in combination with perioperative chemotherapy. An oncological resection includes a radical (R0) gastrectomy and modified D2 lymphadenectomy; generally, a total omentectomy is also performed, to ensure the removal of possible microscopic disease. However, the omentum functions as a regulator of regional immune responses to prevent infections and prevents adhesions which could lead to bowel obstructions.

Information Needs in Patients with Potentially Curable Gastroesophageal Cancer.

Introduction: Gastroesophageal cancer patients' information needs remain understudied, despite their complex treatment trajectories.

Methods: This study examined the (i) information needs of patients with or without postoperative complications, (ii) information needs of male and female patients, and (iii) the association between information needs and health-related quality of life (HR-QoL) following gastroesophageal cancer surgery. Patients completed the EORTC-QLQ-INFO25, QLQ-C30, and QLQ-OG25 questionnaires before and after curative surgery.

Neoadjuvant chemotherapy in older patients with gastric cancer undergoing surgery: a population-based cohort study.

Background: In trials evaluating perioperative chemotherapy for gastric cancer, which serve as the basis for treatment guidelines, patients are selected. The generalizability of these trial findings to older patients is uncertain.

Methods: This population-based retrospective cohort study compared the survival outcomes of patients ≥ 75 years with gastric adenocarcinoma treated with or without neoadjuvant chemotherapy between 2015 and 2019.

Omentectomy as Part of Radical Surgery for Gastric Cancer: 5-Year Follow-Up Results of a Multicenter Prospective Cohort Study.

Introduction: Curative therapy for gastric cancer usually consists of perioperative chemotherapy combined with a radical (R0) gastrectomy. In addition to a modified D2 lymphadenectomy, a complete omentectomy is recommended. However, there is little evidence for a survival benefit of omentectomy.

Staging laparoscopy in patients with advanced gastric cancer: A single center cohort study.

Background: Most studies exploring the role of staging laparoscopy in gastric cancer are limited by low sample size and are predominantly conducted in Asian countries. This study sets out to determine the value of staging laparoscopy in patients with advanced gastric cancer in a Western population.

Methods: All patients with gastric cancer from a tertiary referral center without definite evidence of non-curable disease after initial staging, and who underwent staging laparoscopy between 2013 and 2020, were identified from a prospectively maintained database.
