Understanding how low oxygen levels affect oesophagogastric cancer

Hypoxia Driven Metabolic Response in Oesophagogastric Adenocarcinoma

Imperial College London · NCT06669663

This study is testing how low oxygen levels in tumors affect the behavior of oesophagogastric cancer in patients to find out if it can help improve treatment options.

What this trial studies

This observational study focuses on patients with oesophagogastric adenocarcinoma to investigate the metabolic responses triggered by hypoxia, or low oxygen levels, in tumors. It aims to analyze how these hypoxic conditions contribute to the aggressiveness and treatment resistance of the cancer. Patients will be administered pimonidazole hydrochloride to assess the extent of hypoxia in their tumors, which may reveal important insights into their prognosis and potential treatment options. The study seeks to improve understanding of the relationship between tumor hypoxia and cancer outcomes.

Who should consider this trial

Good fit: Ideal candidates include males and females aged 18-90 with biopsy-proven oesophageal or gastric adenocarcinoma undergoing surgical resection or staging laparoscopy.

Not a fit: Patients with non-adenocarcinoma cancers, recent antibiotic therapy, previous resections, allergies to pimonidazole, or those unable to provide consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better prognostic tools and targeted therapies for patients with oesophagogastric cancer.

How similar studies have performed: While the specific approach of this study may be novel, there is existing literature indicating that understanding tumor hypoxia can lead to improved treatment strategies in cancer care.
