The difference in local control times can be ascribed

to the decision to enroll in the intraoperative group cats with rapidly growing neoplasms, leading to greater electroporation fields. One critical advantage Lazertinib concentration of this technique is the possibility to repeat the treatment in selected patients experiencing local recurrence without the side effects of re-irradiated tissues [26]. A similar study in 22 dogs with soft tissue sarcomas, preferentially treated with a postoperative protocol, yielded a median time to recurrence of 730 days with a 95% response rate, and again hemangiopericytoma showed to be extremely sensitive to ECT, data confirmed by results obtained in cats as well [27, 39]. The side effects of veterinary patients

treated with adjuvant ECT were confined to local inflammation and occasional wound dehiscence [26, 27]. Concurrently, adjuvant ECT has been tested in a cohort of 28 dogs with mast cell sarcomas, resulting in a response rate of 85% and a mean time to recurrence of 52.7 https://www.selleckchem.com/products/ON-01910.html ± 6.5 months, moreover the authors reported that at the time of writing the median time to recurrence was not reached yet, since 24 of the patients were still disease free [28]. Two patients experiencing marginal recurrence were successfully treated with a minor surgery combined with a single application of electrochemotherapy [28]. The use of ECT is not strictly limited to superficial neoplasms: there is also some evidence that trains of biphasic pulses can improve the local control of incompletely excised however deep perianal tumors, with preservation of organ function [35, 36, 40]. Caution

should be exerted when adopting ECT as a rescue in patients that failed radiation therapy. A case report describes a severe radiation recall in a cat treated with adjuvant radiation therapy for a recurring fibrosarcoma [41]. Interestingly, this cat has been locally treated with cisplatin rather than bleomycin and perhaps the reaction has been triggered by the local administration of a platinum compound, since it is among the drugs linked with this type of complication [42]. Table 1 summarizes the results obtained in companion animals carrying spontaneous tumors that have been so far treated with electrochemotherapy.
