Irreversible Electroporation: An Emerging Immunomodulatory Therapy on Solid Tumors

Area of Science:

• Oncology
• Immunology
• Biophysics

Background:

• Irreversible electroporation (IRE) is a non-thermal ablation technique for unresectable solid tumors.
• IRE causes cell death by creating membrane defects with electric pulses.
• Clinical limitations include incomplete ablation and recurrence susceptibility.

Purpose of the Study:

• To review the clinical efficacy of IRE in tumor treatment.
• To summarize IRE-induced immune responses and their mechanisms.
• To analyze IRE combined with immunotherapy for solid tumors.

Main Methods:

• Review of current clinical efficacy of IRE.
• Summary of local and systemic immune responses post-IRE.
• Analysis of IRE-induced immune mechanisms.
• Review of IRE combined with immunotherapy research.
• Assessment of preclinical animal models and clinical research needs.

Main Results:

• IRE releases tumor antigens, acting as an 'in-situ' vaccine.
• IRE can induce antitumor immune responses, potentially killing residual cells and inhibiting metastasis.
• IRE shows potential as an immunomodulatory therapy.

Conclusions:

• IRE combined with immunotherapy offers synergistic effects for malignant tumors.
• Addressing deficiencies in preclinical models is crucial for advancing clinical research.
• IRE holds broad application prospects for novel tumor treatments.
