Brief Summary

Previous studies have shown that irreversible electroporation (IRE) preoperative induction chemotherapy or adjuvant chemotherapy after IRE can reduce the local recurrence rate of locally advanced pancreatic cancer (LAPC) and benefit the survival of patients. According to the technical principle of electroporation therapy (EPT), when the cell membrane is electroporated, the resistance of cell membrane decreases instantaneously, which promotes the drug to enter tumor cells and significantly increases its cytotoxicity and killing effect on tumor tissue. The purpose of study is to evaluate the safety and effectiveness of simultaneous gemcitabine administration and IRE for treating LAPC. In order to provide new ideas for the treatment of LAPC.

Synchronous treatment group

EXPERIMENTAL

Gemcitabine was administered over 30 minutes immediately following percutaneous irreversible electroporation. Gemcitabine was then given once weekly for 2 weeks, followed by a week of rest from treatment. Subsequent cycles consisted of once weekly infusions for 3 consecutive weeks out of every 4 weeks.Treatment continued until disease progression was detected by mRECIST or there was unacceptable toxicity.

Device: Irreversible electroporationDrug: Gemcitabine

Traditional treatment group

ACTIVE COMPARATOR

The initial gemcitabine administration was on day 7 following IRE treatment. Once weekly infusions for 3 consecutive weeks out of every 4 weeks.Treatment continued until disease progression was detected by mRECIST or there was unacceptable toxicity.

Device: Irreversible electroporationDrug: Gemcitabine

Interventions

During the IRE process, we employed a CT scanner and an ultrasound system to guide percutaneous insertion of the electrode probes (one main electrode and one to three standard electrodes were used per treatment). The electrode number, electrode-insertion mode and intraoperative parameters were decided upon during pretreatment planning. The IRE parameters were visually simulated in the pulse generator and set up as follows: energy was applied at 1500 V/cm for 90 ms/pulse for a total of 7-9 pulses. After an initial testing pulse train was discharged to establish the best voltage value, the remaining 80 pulses were completed in 1-2 minutes. After ablation, we confirmed completion of IRE by measuring real-time resistance or current changes, in addition to intraoperative ultrasound and CT.
