About this study
Official title: The Safety and Efficacy of Re-irradiation With Stereotactic Body Radiotherapy for Relapsed Pancreatic Cancer
The safety and efficacy of re-irradiation with stereotactic body radiotherapy for relapsed pancreatic cancer will be evaluated.
Read the detailed description
Pancreatic cancer is one of the most lethal malignant tumors, probably attributable to local recurrence deemed as a predominant factor influencing patients' prognosis and quality of life. Only 15%-20% patients are suitable for surgeries among those first diagnosed with pancreatic cancer and the 5-year survival rate of those patients with R0 resection is still less than 20%. Therefore, radiotherapy is becoming a promising method to improve survival. However, due to adjacent organs at risk, conventional external beam radiotherapy, besides long courses, sometimes results in severe radiation-induced toxicity, delaying the initial of thereafter treatment, such as chemotherapy, which reduces clinical benefits.
A single-fraction dose in the gross tumor volume could be increased stereotactic body radiotherapy (SBRT). Furthermore, doses of organs at risk could also be reduced, thus effectively improving local control rates and reducing radiation related toxicity. Compared with conventional external beam radiotherapy, SBRT is proved to provide longer progression free survival and safe with combination of chemotherapy. Moreover, owing to short courses and low toxicity of SBRT, quality of life is largely improved.
However, it was reported that progression usually occurred 2 years after the initial treatment. The most common failure pattern was local recurrence. Chemotherapy and supportive treatment were commonly used in relapsed pancreatic cancer but with unfavored outcomes. Palliative surgeries are performed in patients with recurrent pancreatic cancer in some studies. Nevertheless, because of bad medical conditions and high complication rates, many patients could not endure surgeries. Therefore, whether patients previously treated with SBRT could be re-irradiated is another challenge in the treatment of pancreatic cancer.
Some studies have confirmed that improved quality of life and longer survival could be available with re-irradiation via SBRT in patients with relapsed pancreatic cancer. Real-time guiding and synchronous tracing of SBRT increase the doses of tumor volumes but decrease doses of organs at risk and toxicity, rendering SBRT as an alternative treatment for relapsed pancreatic cancer. Chris et al. demonstrated that 1-year local control rate was 70% after re-irradiation with SBRT in 14 patients and the toxicity was mild. Nergiz Dagoglu et al. showed that the median overall survival was 14 months and no grade 3, 4 and 5 toxicities occurred.
From 2013-2015, we retrospectively reviewed medical records of 14 patients with relapsed pancreatic cancer re-irradiated with SBRT. All of their tumor markers and pain scores decreased and quality of life improved 3 months after re-irradiation. Hence, based on our experience, we attempt to prospectively evaluate the safety and efficacy of re-irradiation with SBRT for relapsed pancreatic cancer.

Questions about this trial
What is this clinical trial studying?
A study testing Re-irradiation with SBRT in people with Pancreatic Cancer, run by Changhai Hospital at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 10 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 25 May 2023. Status can change between updates, so confirm with the study contact before making plans.
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?
Results are not available in the source record.
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?
The toxicities following SBRT will be determined. (time frame: 3 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02745847, which also lists 20 linked publications.
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 25 May 2023.
