This nanoelectroablation therapy effectively treats subdermal murine allograft tumors, autochthonous basal cell carcinoma (BCC) tumors in Ptch1+/‐K14‐Cre‐ER p53 fl/fl mice, and UV‐induced melanomas in C57/BL6 HGF/SF mice. Here, we described the first human trial of this modality. We treated 10 BCCs on three subjects with 100–1000 electric pulses 100 ns in duration, 30 kV/cm in amplitude, applied at 2 pulses per second. Seven of the 10 treated lesions were completely free of basaloid cells when biopsied and two partially regressed. Two of the 7 exhibited seborrheic keratosis in the absence of basaloid cells. One of the 10 treated lesions recurred by week 10 and histologically had the appearance of a squamous cell carcinoma. No scars were visible at the healed sites of any of the successfully ablated lesions. One hundred pulses were sufficient for complete ablation of BCCs with a single, 1‐min nanoelectroablation treatment.
