What this trial studies

This study aims to evaluate how echo-endoscopic procedures affect the levels of circulating tumor cells (CTCs) in patients suspected of having pancreatic cancer. It will involve 42 patients who will undergo an echo-endoscopic biopsy and/or biliary drainage, with blood samples taken from the portal vein before and after the procedure. The study will analyze the quantity and characteristics of CTCs to assess the impact of the biopsy on tumor cell levels. Follow-up evaluations will occur every six months to monitor disease progression and patient health.

Who should consider this trial

Good fit: Ideal candidates are men and women aged 40-85 suspected of having pancreatic cancer and scheduled for an echo-endoscopic biopsy.

Not a fit: Patients with visible carcinosis, ascites, or those unable to consent or follow the study protocol may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the management of pancreatic cancer by providing insights into the effectiveness of echo-endoscopic procedures.

How similar studies have performed: While the specific approach of this study may be novel, similar studies assessing circulating tumor cells have shown promise in other cancer types.
