Background: Patients with early esophageal cancer experience varying clinical outcomes despite identical tumor staging by standard diagnostic methods because clinical and histopathological staging fail to reveal the underlying complex biology of cancer.
Methods And Focus: This review discusses some of the current concepts of molecular staging with the potential to enhance the current staging methods of patients with early esophageal cancer.
Conclusions: Understanding the molecular biology of esophageal cancer has increased substantially, and clinicians anticipate the translation of the gained knowledge into patient care. Numerous molecular techniques are potentially available for analyzing biological aspects of the individual tumor for improved staging.

Malnutrition Diagnosed by Patient-Generated Subjective Global Assessment and the Risk of All-Cause Mortality in Adults With Gastrointestinal Cancer: A Systematic Review and Meta-Analysis.
J Hum Nutr Diet
February 2025
Department of Surveillance and Health Services Research, American Cancer Society, Atlanta, Georgia, USA.
Introduction: Several reviews have highlighted that the Patient-Generated Subjective Global Assessment (PG-SGA) is the best diagnostic tool for assessing nutritional status in cancer patients. However, previous meta-analyses summarizing the prevalence of malnutrition and overall survival in patients with gastrointestinal (GI) cancer are quite limited. This study aims to determine the overall prevalence and association between malnutrition, as defined by the PG-SGA, and mortality in adults with GI cancer.

Background: Transforming growth factor-β (TGF-β) superfamily plays an important role in tumor progression and metastasis. Activin A receptor type 1C (ACVR1C) is a TGF-β type I receptor that is involved in tumorigenesis through binding to different ligands.
Aim: To evaluate the correlation between single nucleotide polymorphisms (SNPs) of ACVR1C and susceptibility to esophageal squamous cell carcinoma (ESCC) in Chinese Han population.
A conceptual model for advanced/metastatic gastric or gastroesophageal junction cancer: a review of qualitative studies and results from patient interviews.

Patient Centered Solutions, IQVIA, Reading, UK.
Background: Despite approvals of new first-line immunotherapies for advanced/metastatic gastric cancer/gastroesophageal junction cancer (aGC/GEJC), patients' median survival is around 14 months and their health-related quality of life (HRQoL) is affected by disease-related symptoms and treatment-related side effects. Using a targeted literature review (TLR) and patient interviews, this study identified disease- and treatment-related concepts that are important to patients with aGC/GEJC and their HRQoL.
Methods: A TLR was conducted to identify primary qualitative studies from 2018 to 2021 on patients' experiences with aGC/GEJC.

Background: The delivery of cancer services changed significantly during the COVID-19 pandemic. This study aimed to describe changes in presentations, assess the change in recommendations by the MDT during the pandemic, and describe the subsequent long-term impact of these changes on survival rates in patients with EG cancer.
Methods: A retrospective cohort study was designed comparing three patient groups of those referred to EG MDT in the same 6-month period pre-pandemic (PP;2019) during the initial phase of the pandemic (P1;2020) and the year after the initial phase (P2;2021).
PYGO2 promotes resistance to chemotherapy via reducing apoptosis and G2/M cell cycle arrest in esophageal carcinoma cells.

5-FU is a widely used chemotherapy drug for esophageal carcinomas, but therapy failure has been observed in 5-FU-resistant patients. Overcoming this resistance is a significant challenge in cancer treatment, requiring identifying and targeting important resistance mechanisms. PYGO2 expression is crucial in developing resistance to various chemotherapy drugs.
