To evaluate the feasibility and immune modulation capacity of unipolar and symmetric bipolar sub-microsecond pulses in calcium electrochemotherapy (CaECT), with a focus on comparing their effectiveness.
Key Findings:
Bipolar pulses showed pronounced modulation of lymph-node immune composition, suggesting potential for enhanced immune response.
Unipolar pulses resulted in a clearer increase in central memory T-cell populations, indicating a different immune activation profile.
The bipolar cancellation phenomenon was not observed in vivo as predicted by in vitro data, highlighting a discrepancy that warrants further investigation.
Interpretation:
Bipolar sub-microsecond pulses may offer advantages in terms of immune modulation and treatment uniformity compared to unipolar pulses, despite the in vitro observations of bipolar cancellation, suggesting a need for further exploration in clinical settings.
Limitations:
Limited understanding of in vivo effects of bipolar pulses compared to in vitro data, indicating a gap in knowledge that needs addressing.
Potential variability in tissue conductivity and immune engagement not fully captured, suggesting the need for more comprehensive studies.
Conclusion:
Bipolar CaECT may enhance immune responses and treatment efficacy, warranting further investigation into its clinical applications and potential integration into existing cancer therapies.
