About this study
Official title: Recurrence-pattern-based Volume Versus Conventional-volume Stereotactic Body Radiation Therapy in Locally Advanced Pancreatic Cancer: an Open-label, Randomized, Phase 2 Trial
The purpose of this study is to compare the efficacy and safety of a recurrence-pattern-based-volume versus conventional-volume stereotactic body radiation therapy for locally advanced pancreatic cancer, so as to determine whether the target delineation method based on recurrence pattern can obtain better survival benefits.
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
SBRTRadiation
A conventional-volume stereotactic body radiation therapy: planning target volume should include gross tumor volume with a uniform 3mm margin in all directions.
A recurrence-pattern-based volume stereotactic body radiation therapy: planning target volume should include gross tumor volume with a 3mm margin in the anterior and lateral directions, 10mm margin in the cranial and caudal directions that should cover the full circumstance of celiac artery and superior mesenteric artery, 15mm in the posterior direction that should cover the retroperitoneal space.
The prescribed dose of PTV varies from 30-50Gy/5-6f.
ChemotherapyDrug
Gemcitabine (1000mg/m2，d1, 8) + albumin-bound paclitaxel (125mg/m2，d1, 8) , repeat every 3 weeks for 6 cycles
| Study group | Role | What they receive |
|---|---|---|
| Arm A | Active comparator | A conventional-volume stereotactic body radiation therapy following gemcitabine and nab-paclitaxel Receives: Radiation: SBRT; Drug: Chemotherapy |
| Arm B | Experimental | A recurrence-pattern-based-volume stereotactic body radiation therapy following gemcitabine and nab-paclitaxel Receives: Radiation: SBRT; Drug: Chemotherapy |

Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 10 Dec 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
1-year Progression Free Survival Rate (time frame: 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Dec 2025.
