What this trial studies

This study aims to evaluate the efficacy and safety of two different target delineation methods in stereotactic body radiation therapy (SBRT) for patients with locally advanced pancreatic cancer (LAPC). By comparing these methods, the study seeks to determine if a target delineation approach based on recurrence patterns can lead to improved survival outcomes. Participants will receive SBRT in conjunction with chemotherapy, and their responses will be monitored to assess the effectiveness of the treatment. The study is designed for patients who have not undergone prior anti-tumor treatments related to the pancreas.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-75 with a diagnosis of locally advanced pancreatic cancer who have not received prior treatment.

Not a fit: Patients with severe liver or kidney dysfunction, or those who have previously received treatment for pancreatic cancer, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved survival rates for patients with locally advanced pancreatic cancer.

How similar studies have performed: While there have been studies on SBRT for pancreatic cancer, the specific comparison of target delineation methods based on recurrence patterns is a novel approach.
