Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 18 to 75 years with a confirmed diagnosis of pancreatic ductal adenocarcinoma.

Probably not a fit

Patients with other concurrent malignancies or those unable to follow a specific anti-cancer treatment plan may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical study aims to evaluate the prognosis of patients with pancreatic ductal adenocarcinoma (PDAC) by combining the detection of Lewis antigens with the CA19-9 biomarker. It employs a prospective, multicenter design to classify patients based on their Lewis antigen status and CA19-9 levels, observing their survival outcomes. The study will also assess the sensitivity and specificity of Lewis antigen detection in both pancreatic cancer patients and non-cancer subjects. By analyzing the relationship between Lewis subtypes, age, and overall survival, the study seeks to enhance prognostic accuracy for pancreatic cancer.

Why it matters

Potential benefit: If successful, this study could provide a more accurate prognostic tool for patients with pancreatic cancer, potentially guiding treatment decisions.

How similar studies have gone: While the combination of Lewis antigen and CA19-9 testing is a novel approach, similar studies have shown promise in improving prognostic assessments in cancer.
