Span-C-SBRT for Pancreatic Cancer
Study Details
Study Description
Brief Summary
To assess the freedom from local failure at 12 months after Stereotactic Body Radiotherapy (SBRT). Also to assess the safety, efficacy and feasibility of SBRT in the treatment of high risk localised pancreatic cancer.

Detailed Description
Patients must have histologically or cytologically confirmed high risk localised adenocarcinoma of the pancreas, including patients with extrapancreatic extension (Stage IIA), node positive (Stage IIB), borderline resectable or locally advanced pancreatic cancer as defined by Australasian Gastro-Intestinal Trials Group (AGITG) guidelines. ECOG performance status 0-1, suitable for chemotherapy and radiotherapy.
After a minimum of 2 months of neoadjuvant chemotherapy using either an oxaliplatin- based regimen (FOLFOX, FOLFIRINOX, mFOLFIRINOX)+/- immunotherapy/molecular agent or gemcitabine based chemotherapy (eg gemcitabine / gemcitabine/abraxane). Participants will receive SBRT (30-45Gray in 5 fractions over 2 weeks. Prior to SBRT, fiducial markers will be placed to aid with image guidance during radiation delivery. Four weeks after completion of SBRT participants will have re-staging using positron emission tomography (PET) and computed tomography (CT) scan. Participants will be discussed in the multidisciplinary team meeting for consideration of surgery. Those considered to be resectable will proceed to have surgery 6-10 weeks post SBRT.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Stereotactic Body Radiotherapy (SBRT) Prior to SBRT, fiducial markers will be placed to aid with image guidance during radiation delivery. Fiducials will be inserted endoscopically (preferable) or intraoperatively. After this procedure, patients will have radiotherapy planning. During treatment, the fiducials will be used for registration with the images acquired during treatment (including kV fluoroscopy, MV or optical). The acquired images may be processed to determine fiducial location using KIM or MATT software from University of Sydney. SBRT 30-45Gray in 5 fractions will be given over 2 weeks. Four weeks after completion of SBRT participants will repeat a re-staging PET and CT scans. Those considered to be resectable will proceed to have surgery 6-10 weeks post SBRT. |
Radiation: Stereotactic Body Radiotherapy (SBRT)
Stereotactic Body Radiotherapy (SBRT) 30-45 gray in 5 fractions over 2 weeks will be given to all eligible patients.

Outcome Measures
Primary Outcome Measures
- freedom of local failure [12 months from end of radiotherapy]
patient who do no have local failure
Secondary Outcome Measures
- Incidence of SBRT treatment related adverse events in this group of patients [Acute toxicity-from start of SBRT up to 3 months after SBRT. Late RT toxicity: from 3 months to 2 years after SBRT.]
assess acute and late radiotherapy toxicity using CTCAE version 4.3, to compare toxicity with conventional treatment
- Response to neoadjuvant treatments [from date of surgery through to 24 months post surgery]
Determine by pathology and radiological response rates after neoadjuvant treatment,
- Feasibility of internal-external correlation model (MATT) [during SBRT radiotherapy treatment]
Determine the feasibility of the University of Sydney internal-external correlation model (MATT) to determine pancreas motion. Feasibility is determined as predicted motion with MATT is within 2mm of actual motion measured with fluoroscopic x-rays of fiducial markers during treatment.
- Surgical complications [30 to 90 days post surgery]
To assess surgical complications
- Duration of hospital admission after surgery [from date of surgery through study completion (ie 24 months)]
to assess extended stay in the hospital after surgery
- margin negative (R0) resection rate [through study completion, average of 2 years]
to assess margin negative resection rate (i.e. response to treatment)
- median overall survival (OS) [12 months after treatment]
To assess median overall survival after treatment
- progression free survival (PFS) [12 months after treatment]
To assess the PFS rate after treatment
- Feasibility of Using Kilovoltage Intra-fraction Monitoring (KIM) to determine pancreas motion [during SBRT radiotherapy treatment]
Determine the feasibility of the University of Sydney Kilovoltage Intra-fraction Monitoring (KIM) software to determine pancreas motion. Feasibility is determined as predicted motion with KIM is within 2mm of actual motion measured with fluoroscopic x-rays of fiducial markers during treatment.
