Eligibility
Key inclusion criteria
1. A diagnosis of a pancreatic cystic tumour based on multidisciplinary review of
imaging, for which further surveillance with non-invasive imaging is indicated.

2. Pancreatic cystic tumour between 0.5 and 3cm in size. Cysts greater than 3cm or with
mural nodules can be included only if patients are unsuitable for surgical resection.

3. ECOG performance status 0, 1 or 2.

4. Estimated life expectancy of at least 12 weeks.

5. Age >18 years.

6. Capable of giving written informed consent.

7. Women of child-bearing potential must have a negative pregnancy test (qualitative
serum hCG) in the week before treatment, AND be using an adequate contraception
method, which must be continued for at least 1 week after RF.
Minimum age
18 Years
Maximum age
No limit
Gender
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. A diagnosis of a pancreatic cystic tumour where surgical resection is indicated.

2. Pancreatic cysts greater than 3cm or less than 0.5cm in size.

3. Benign pancreatic cysts (e.g. pseudocyst).

4. Serous cystadenomas.

5. Pancreatic cysts with malignant transformation.

6. Cysts involving or in close proximity to vessels or the biliary tree where the zone of
ablation is likely to compromise these structures.

7. Cysts arising from the main pancreatic duct.

8. History of active or prior malignancy that will interfere with the response evaluation
(exceptions include in-situ carcinoma of the cervix treated by cone-biopsy/resection,
nonmetastatic basal and/or squamous cell carcinomas of the skin, any early stage
(stage l) malignancy adequately resected for cure greater than 5 years previously).

9. Acute pancreatitis within the previous 4 weeks.

10. Any evidence of severe or uncontrolled systemic diseases or laboratory finding that in
the view of the investigator makes it undesirable for the patient to participate in
the trial.

11. Any psychiatric disorder making reliable informed consent impossible.

12. Pregnancy or breast-feeding.

13. ECOG performance status 3 or 4

Summary
Brief summary
Up to 13.5% of patients that undergo a magnetic resonance imaging (MRI) scan of their abdomen
without pancreatic symptoms are found to have an incidental pancreatic cyst, with the
frequency increasing with age. In a post-mortem series, 25% of patients had a pancreatic
cyst, of which 32% were potentially premalignant and 3% malignant. Premalignant cysts are
currently either observed or removed surgically according to international guidelines.
Observation is associated with significant anxiety for patients and a growing cost to the
National Health Service, while surgery for this usually benign condition is associated with
not insignificant morbidity and mortality. Premalignant pancreatic cysts may be indolent for
a number of years before malignant transformation, creating a window of opportunity for
minimally invasive intervention and cure. New early treatment options for premalignant
tumours are urgently required. This study will evaluate the safety and efficacy of a novel
minimally invasive technique for the treatment of pancreatic cystic tumours; endoscopic
ultrasound guided radiofrequency ablation (EUSRFA).

If successful it will offer an alternative to long term observation or surgery for patients
with this condition.
