Anti-Tumor Immunity Induced by IRE of Unresectable Pancreatic Cancer
IRE: Anti-Tumor Immunity Induced by IRE of Unresectable Pancreatic Cancer
Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
Thirty patients with histologically confirmed locally advanced pancreatic adenocarcinoma (≤5.0cm) will undergo percutaneous irreversible electroporation of the tumor using CT and ultrasound guidance. Blood will be drawn for research before IRE. Blood and tissue samples will be used.
After IRE, patients will be carefully monitored and systemic immune responses are registered. Follow-up will consist of frequent CT and MRI scanning, as well as serum CA19.9 tumor marker and quality of life questionnaires and overall survival (OS).
The investigators hypothesize that IRE in the pancreas will induce good symptom palliation without causing severe complications as well as perfect systemic immune response.

Description
Inclusion Criteria:
- Radiologic confirmation of unresectable pancreatic cancer by at least CT of chest and abdomen
- Screening must be performed no longer than 2 weeks prior to study inclusion
- Maximum tumor diameter ≤ 5 cm;
- Histological or cytological confirmation of pancreatic adenocarcinoma;
- Age ≥ 18 years;
- ASA-classification 0 - 3
- Life expectancy of at least 12 weeks;
Adequate bone marrow, liver and renal function as assessed by the following laboratory requirements to be conducted within 7 days prior to definite inclusion;
- Hemoglobin ≥ 5.6 mmol/L;
- Absolute neutrophil count (ANC) ≥ 1,500/mm3;
- Platelet count ≥ 100*109/l;
- Total bilirubin ≤ 1.5 times the upper limit of normal (ULN);
- ALT and AST ≤ 2.5 x ULN;
- Serum creatinine ≤ 1.5 x ULN or a calculated creatinine clearance ≥ 50 ml/min;
- Prothrombin time or INR < 1.5 x ULN;
- Activated partial thromboplastin time < 1.25 x ULN (therapeutic anticoagulation therapy is allowed if this treatment can be interrupted as judged by the treating physician);
- Written informed consent;
Exclusion Criteria:
- Resectable pancreatic adenocarcinoma as discussed by our multidisciplinary hepatobiliary team;
- Successful down staging after (radio)chemotherapy from previous unresectable/borderline tumor to resectable tumor;
- History of epilepsy;
History of cardiac disease:
- Congestive heart failure >NYHA class 2;
- Active Coronary Artery Disease (defined as myocardial infarction within 6 months prior to screening);
- Cardiac arrhythmias requiring anti-arrhythmic therapy or pacemaker (beta blockers for antihypertensive regimen are permitted);
- Uncontrolled hypertension. Blood pressure must be ≤160/95 mmHg at the time of screening on a stable antihypertensive regimen;
- Compromised liver function (e.g. signs of portal hypertension, INR > 1,5 without use of anticoagulants, ascites);
- Uncontrolled infections (> grade 2 NCI-CTC version 3.0);
- Pregnant. Women of childbearing potential must have a negative pregnancy test performed within 7 days of the start of treatment;
- Immunotherapy ≤ 6 weeks prior to the procedure;
- Chemotherapy ≤ 6 weeks prior to the procedure;
- Radiotherapy ≤ 6 weeks prior to the procedure;
- Concomitant use of anti-convulsive and anti-arrhythmic drugs (other than beta blockers used for antihypertensive);
- Allergy to contrast media;
- Any implanted stimulation device;
- Any implanted metal stent/device within the area of ablation that cannot be removed;
- Any condition that is unstable or that could jeopardize the safety of the subject and their compliance in the study; Of note, patients with contra-indications for MRI will not be excluded from participation: in this case radiologic follow-up will consist of CT-scanning according to protocol.

Experimental: NanoKnife LEDC System
90 pulses of 70 microseconds each in duration will be administered per electrode pair.
|
Irreversible electroporation (IRE) is a new, minimal-invasive image-guided treatment method for tumors not amenable for surgical resection or thermal ablation, due to vicinity near vital structures such as vessels and bile ducts.
With IRE, multiple electrical pulses are applied to tumorous tissue.
These pulses alter the existing transmembrane potential of the cell membranes, and create 'nanopores', after which the cell dies through loss of homeostasis.
