Impact of FDG-PET/CT and Laparoscopy in Staging of Locally Advanced Gastric Cancer: A Cost Analysis in the Prospective Multicenter PLASTIC-Study.

Background: Unnecessary D2-gastrectomy and associated costs can be prevented after detecting non-curable gastric cancer, but impact of staging on treatment costs is unclear. This study determined the cost impact of F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) and staging laparoscopy (SL) in gastric cancer staging.

Materials And Methods: In this cost analysis, four staging strategies were modeled in a decision tree: (1) FDG-PET/CT first, then SL, (2) SL only, (3) FDG-PET/CT only, and (4) neither SL nor FDG-PET/CT.

Minimally invasive versus open gastrectomy for gastric cancer. A pooled analysis of two European randomized controlled trials.

Introduction: Minimally invasive techniques have shown better short term and similar oncological outcomes compared to open techniques in the treatment of gastric cancer in Asian countries. It remains unknown whether these outcomes can be extrapolated to Western countries, where patients often present with advanced gastric cancer.

Materials And Methods: A pooled analysis of two Western randomized controlled trials (STOMACH and LOGICA trial) comparing minimally invasive gastrectomy (MIG) and open gastrectomy (OG) in advanced gastric cancer was performed.

Pain and Opioid Consumption After Laparoscopic Versus Open Gastrectomy for Gastric Cancer: A Secondary Analysis of a Multicenter Randomized Clinical Trial (LOGICA-Trial).

Background: Laparoscopic gastrectomy could reduce pain and opioid consumption, compared to open gastrectomy. However, it is difficult to judge the clinical relevance of this reduction, since these outcomes are reported in few randomized trials and in limited detail.

Methods: This secondary analysis of a multicenter randomized trial compared laparoscopic versus open gastrectomy for resectable gastric adenocarcinoma (cT1-4aN0-3bM0).

Cost-effectiveness of Laparoscopic vs Open Gastrectomy for Gastric Cancer: An Economic Evaluation Alongside a Randomized Clinical Trial.

Importance: Laparoscopic gastrectomy is rapidly being adopted worldwide as an alternative to open gastrectomy to treat gastric cancer. However, laparoscopic gastrectomy might be more expensive as a result of longer operating times and more expensive surgical materials. To date, the cost-effectiveness of both procedures has not been prospectively evaluated in a randomized clinical trial.

Learning Curve of Laparoscopic Gastrectomy: A Multicenter Study.

Objective: To evaluate the learning curve of laparoscopic gastrectomy (LG) after an implementation program.

Design, Setting, And Participants: This multicenter prospective, observational cohort study included 394 patients with locally advanced, clinically curable gastric adenocarcinoma (≥cT3 and/or N+, M0 category based on CT) between August 1, 2017, and February 1, 2020.

Laparoscopic Versus Open Gastrectomy for Gastric Cancer (LOGICA): A Multicenter Randomized Clinical Trial.

Background: The oncological efficacy and safety of laparoscopic gastrectomy are under debate for the Western population with predominantly advanced gastric cancer undergoing multimodality treatment.

Methods: In 10 experienced upper GI centers in the Netherlands, patients with resectable (cT1-4aN0-3bM0) gastric adenocarcinoma were randomly assigned to either laparoscopic or open gastrectomy. No masking was performed.

[Trials, observational research and the real world].

The treatment effect found in a randomized trial does not always correspond to the effect of the treatment in daily practice. To estimate the applicability of the results of a trial, a comparison can be made with the results of observational research. In this commentary we discuss such a comparison between the results of the TIME trial and the analysis of the observational DUCA database.

Objective: To identify the most prevalent symptoms and those with greatest impact upon health-related quality of life (HRQOL) among esophageal cancer survivors.

Background: Long-term symptom burden after esophagectomy, and associations with HRQOL, are poorly understood.

Patients And Methods: Between 2010 and 2016, patients from 20 European Centers who underwent esophageal cancer surgery, and were disease-free at least 1 year postoperatively were asked to complete LASER, EORTC-QLQ-C30, and QLQ-OG25 questionnaires.

The additive value of restaging-CT during neoadjuvant chemotherapy for gastric cancer.

Introduction: Computed tomography (CT) is used for restaging of gastric cancer patients during neoadjuvant chemotherapy (NAC). The treatment strategy could be altered after detection of distant interval metastases, possibly leading to a reduction in unnecessary chemotherapy cycles, its related toxicity, and surgical procedures. The aim of this study was to evaluate the additive value of restaging-CT during NAC in guiding clinical decision making in gastric cancer.

Do esophageal cancer survivors work after esophagectomy and do health problems impact their work? A cross-sectional study.

Purpose: This study aimed to evaluate the occupational status and work impediments due to health problems in long-term esophageal cancer survivors.

Methods: The Short-Form Health and Labour Questionnaire (SF-HLQ) was sent to esophageal cancer survivors. Primary outcomes included the number of working esophageal cancer survivors and the patient-reported impact of health problems on work, as evaluated by the SF-HLQ.

Prophylactic Hyperthermic Intraperitoneal Chemotherapy (HIPEC) for Gastric Cancer-A Systematic Review.

Survival after potentially curative treatment of gastric cancer remains low, mostly due to peritoneal recurrence. This descriptive review gives an overview of available comparative studies concerning prophylactic hyperthermic intraperitoneal chemotherapy (HIPEC) for patients with gastric cancer with neither clinically evident metastases nor positive peritoneal cytology who undergo potentially curative gastrectomy. After searching the PubMed, Embase, CDSR, CENTRAL and ASCO meeting library, a total of 11 studies were included comparing surgery plus prophylactic HIPEC versus surgery alone (SA): three randomised controlled trials and eight non-randomised comparative studies, involving 1145 patients.

Identification of the clinically most relevant postoperative complications after gastrectomy: a population-based cohort study.

Background: Postoperative complications frequently occur after gastrectomy for gastric cancer and are associated with poor clinical outcomes, such as mortality and reoperations. The aim of study was to identify the clinically most relevant complications after gastrectomy, using the population-attributable fraction (PAF).

Methods: Between 2011 and 2017, all patients who underwent potentially curative gastrectomy for gastric adenocarcinoma were included from the Dutch Upper GI Cancer Audit.

Resection of hepatic and pulmonary metastasis from metastatic esophageal and gastric cancer: a nationwide study.

The standard of care for gastroesophageal cancer patients with hepatic or pulmonary metastases is best supportive care or palliative chemotherapy. Occasionally, patients can be selected for curative treatment instead. This study aimed to evaluate patients who underwent a resection of hepatic or pulmonary metastasis with curative intent.

Safety and efficacy of early oral feeding for enhanced recovery following gastrectomy for gastric cancer: A systematic review.

Background: Early oral feeding (EOF) is believed to be a crucial item of Enhanced Recovery After Surgery (ERAS) programs. Though this is widely accepted for colorectal surgery, evidence for early oral feeding after gastrectomy is scarce. The aim of this review is to assess the evidence of safety and benefits of early oral feeding after gastrectomy in patients with gastric cancer.

Imaging strategies in the management of gastric cancer: current role and future potential of MRI.

Accurate preoperative staging of gastric cancer and the assessment of tumor response to neoadjuvant treatment is of importance for treatment and prognosis. Current imaging techniques, mainly endoscopic ultrasonography (EUS), computed tomography (CT) and F-fluorodeoxyglucose positron emission tomography (F-FDG PET), have their limitations. Historically, the role of magnetic resonance imaging (MRI) in gastric cancer has been limited, but with the continuous technical improvements, MRI has become a more potent imaging technique for gastrointestinal malignancies.
