Span-C-SBRT for Pancreatic Cancer

Not Applicable
Recruiting
Conditions
High Risk Localised Pancreatic Cancer
Interventions
Radiation: Stereotactic Body Radiotherapy (SBRT)
Registration Number
NCT03505229
Lead Sponsor
Royal North Shore Hospital
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.

Stereotactic Body Radiotherapy (SBRT)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.
Primary Outcome Measures
NameTimeMethod
freedom of local failure12 months from end of radiotherapy

patient who do no have local failure

Secondary Outcome Measures
NameTimeMethod
progression free survival (PFS)12 months after treatment

To assess the PFS rate after treatment

Response to neoadjuvant treatmentsfrom date of surgery through to 24 months post surgery

Determine by pathology and radiological response rates after neoadjuvant treatment,

Incidence of SBRT treatment related adverse events in this group of patientsAcute 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

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.

median overall survival (OS)12 months after treatment

To assess median overall survival after treatment

Surgical complications30 to 90 days post surgery

To assess surgical complications

Duration of hospital admission after surgeryfrom date of surgery through study completion (ie 24 months)

to assess extended stay in the hospital after surgery

margin negative (R0) resection ratethrough study completion, average of 2 years

to assess margin negative resection rate (i.e. response to treatment)

Feasibility of Using Kilovoltage Intra-fraction Monitoring (KIM) to determine pancreas motionduring 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.
