Abstract

To evaluate the safety of the NanoKnife Low Energy Direct Current (LEDC) System (Irreversible Electroporation, IRE) in order to treat patients with unresectable pancreatic adenocarcinoma. Prospective, nonrandomized, single-center clinical evaluation of ten patients with a cytohystological diagnosis of unresectable locally advanced pancreatic cancer (LAPC) that was no further responsive to standard treatments. The primary outcome was the rate of procedure-related abdominal complications. The secondary endpoints included the evaluation of the short-term efficacy of IRE through the evaluation of tumor reduction at imaging and biological tumor response as shown by CA 19-9, clinical assessments and patient quality of life. Ten patients (5 males, 5 females) were enrolled, with a median age of 66 and median tumor size of 30 mm. All patients were treated successfully with a median procedure time of 79.5 min. Two procedure-related complications were described in one patient (10%): a pancreatic abscess with a pancreoduodenal fistula. Three patients had early progression of disease: one patient developed pulmonary metastases 30 days post-IRE and two patients had liver metastases 60 days after the procedure. We registered an overall surviv...Continue Reading

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
