Analyzing bacterial overgrowth in pancreatic cancer patients

A Prospective Study to Assess the Prevalence of Small Intestinal Bacterial Overgrowth (SIBO) in Pancreatic Adenocarcinoma (PDAC) Patients With Weight Loss

Observational Cedars-Sinai Medical Center · NCT06988150

This study is testing how common bacterial overgrowth is in pancreatic cancer patients who are losing weight and seeing if it relates to their surgery status.

What this trial studies

This observational study aims to prospectively analyze the prevalence of small intestinal bacterial overgrowth (SIBO) in patients diagnosed with pancreatic adenocarcinoma (PDAC) who are experiencing clinically significant weight loss. The study will enroll 100 patients and utilize the Lactulose Hydrogen Breath Test to assess SIBO presence. Additionally, it will explore the association between SIBO prevalence and the patients' pancreatic resection status. The findings could enhance understanding of the gastrointestinal complications faced by PDAC patients.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with a diagnosis of pancreatic ductal adenocarcinoma and clinically significant weight loss.

Not a fit: Patients who are minors, pregnant, or have received treatment for SIBO in the past three months may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved management of weight loss and nutritional deficiencies in pancreatic cancer patients.

How similar studies have performed: While there is limited understanding of SIBO prevalence in PDAC patients, similar studies have indicated potential associations between gastrointestinal issues and pancreatic cancer, suggesting this approach may yield valuable insights.
