BACKGROUND: Calcium electroporation is a novel anticancer treatment, which utilizes high voltage pulses to permeabilize cell membranes and expose the cell to supraphysiological doses of calcium. Preclinical studies on calcium electroporation have shown strikingly high tumor response with cell necrosis. Calcium electroporation builds on the treatment electrochemotherapy, where chemotherapeutic drugs, mostly bleomycin, are internalized by electroporation. This double-blinded randomized study compared calcium electroporation to electrochemotherapy in terms of objective response measured 6 months after treatment...

The combination of Irreversible Electroporation and Electrochemotherapy (IRECT) was well tolerated, safe, and had antitumor activity in this case study of a patient with lymph node metastases from gastric cancer. We therefore recommend the consideration of further clinical studies to investigate the treatment of cancerous tissue with IRECT.

Triple negative breast cancer (TNBC) is difficult to treat due to lack of the three receptors, commonly used for treating breast cancers. Current standard of cure is either ineffective or refractive to many patients. Thus, there is a critical need for alternate, affordable therapies for TNBC cancers. Towards this, electrical pulse-mediated chemotherapy, known as electrochemotherapy is a viable option, because it uses the synergy of electrical pulses and the anticancer properties of chemo drug. Considering the cost and the harsh side effects of various commonly administered chemo drugs, in this study, low cost, yet effective, natural phytochemical curcumin is studied for its anticancer effect on MDA-MB-231, TNBC cells...

AIM: To report early imaging assessment of ablated area post electrochemotherapy (ECT) in patients with locally advanced pancreatic cancer (LAPC). METHODS: ECT was performed in 19 LAPC patients enrolled in an approved ongoing clinical phase I/II study. Before and after ECT, 18 patients underwent computed tomography (CT) scan, 11 patients underwent morphological and functional magnetic resonance (MR) scan (dynamic contrast enhanced-MRI) calculating wash-in slope (WIS) and wash-out slope (WOS); diffusion weighted imaging calculating pseudo-diffusivity (Dp), perfusion fraction (fp) and tissue diffusivity (Dt); 10 patients underwent positron emission tomography (PET)...

Pulsed electric fields applied to cells have been used as an invaluable research tool to enhance delivery of genes or other intracellular cargo, as well as for tumor treatment via electrochemotherapy or tissue ablation. These processes involve the buildup of charge across the cell membrane, with subsequent alteration of transmembrane potential that is a function of cell biophysics and geometry. For traditional electroporation parameters, larger cells experience a greater degree of membrane potential alteration...

Changes in optical and shape-related characteristics of B16F10 cells after electroporation were investigated using digital holographic microscopy (DHM). Bipolar rectangular pulses specific for electrochemotherapy were used. Electroporation was performed in an "off-axis" DHM set-up without using exogenous markers. Two types of cell parameters were monitored seconds and minutes after pulse train application: parameters addressing a specifically defined area of the cell (refractive index and cell height) and global cell parameters (projected area, optical phase shift profile and dry mass)...

A twenty-year-old female saddle horse was referred for evaluation of a seven month, non-healing erosive lesion of the right hind hoof with proliferation and bleeding of the underlying soft tissues. This lesion had been twice surgically treated as a canker but rapidly recurred. Histological examination of the second excision revealed a well-differentiated squamous cell carcinoma. At presentation, the horse was mildly depressed, lame and partially non-weight-bearing on the right hind leg, which exhibited a 10 x 10 cm erosive and proliferative lesion remodeling the hoof...

Electrochemotherapy of colorectal liver metastases has been proven to be feasible, safe and effective in a phase I/II study. In that study, a specific group of patients underwent two-stage operation, and the detailed histopathological evaluation of the resected tumors is presented here. Regressive changes in electrochemotherapy-treated liver metastases were evaluated after the second operation (in 8-10 weeks) in 7 patients and 13 metastases when the treated metastases were resected. Macroscopic and microscopic changes were analyzed...

BACKGROUND: Electrochemotherapy (ECT) has shown to be an effective treatment for cutaneous and subcutaneous Kaposi sarcoma (KS) lesions. However, no study has investigated the impact of ECT treatment on the kinetics of human herpesvirus type 8 (HHV8), which is considered the necessary causal agent of KS. We aimed to evaluate HHV8 viral load and expression levels in patients affected by classic KS who received one or more ECT treatments and have been followed semi annually for up to four years...

OBJECTIVE: Electrochemotherapy (ECT) is a combination of electroporation (EP) and chemotherapy and has been reported as a potential radiosensitizing agent for radiation therapy. The main objective of this study was to systematically review of the literature to evaluate the effectiveness of ECT in sensitization of tumors to ionization radiation. In addition, the clinical considerations and mechanisms of action of radiosensitizing effect are discussed. METHODS: The databases of Medline (PubMed), Embase, Scopus, Cochrane library, Web of Science, Biomed central, Science Direct, and Google scholar up to March 30th 2017 were explored...

Electroporation is used in cancer treatment because of its ability to increase local cytotoxicity of e.g. bleomycin (electrochemotherapy) and calcium (calcium electroporation). Calcium electroporation is a novel anticancer treatment that selectively kills cancer cells by necrosis, a cell death pathway that stimulates the immune system due to high release of antigens and "danger signals." In this exploratory study, we aimed to investigate whether calcium electroporation could initiate an anticancer immune response similar to electrochemotherapy...

BACKGROUND AND OBJECTIVES: Electrochemotherapy is a novel ablation technique combining chemotherapeutic agents with reversible cell membrane electroporation. Previous experiences have shown its efficacy for cutaneous tumors. Its application for deep-seated malignancies is under investigation. We performed a prospective, pilot study to evaluate the feasibility, safety, and efficacy of intraoperative electrochemotherapy for otherwise unresectable colorectal liver metastases. METHODS: Electrochemotherapy with bleomycin was combined with open liver resection and performed with linear or hexagonal needle electrodes according to an individualized pretreatment plan...

BACKGROUND: Electrochemotherapy (ECT), by combining manageable cytotoxic agents with short electric pulses, represents an effective palliative skin-directed therapy. The accumulated evidence indicates that ECT stands out as a safe and well-tolerated alternative treatment for patients with multiple or large basal cell carcinoma (BCC), who are not suitable for conventional treatments. However, long-term data and shared indications are lacking. METHODS: In this observational study, we retrospectively analyzed 84 prospectively collected patients with multiple, recurrent or locally advanced BCC who were not candidate for standard therapies and received bleomycin-based ECT according to the European Standard Operative Procedures of ECT, from 2006 to 2016...

Electrochemotherapy (ECT) is a new local treatment method for solid and superficial tumors. During this new technique, patients experience an unpleasant sensation and slight edema. Most unpleasant and painful is mainly attributed to muscle contractions provoked by high amplitude and low repetition frequency pulses. Recently, we showed that electrochemotherapy using low voltage and higher repetition frequency (LVHF ECT) is an effective tool for inhibiting tumor growth and inducing cell permeabilization. Low voltage high-frequency electrochemotherapy was developed and optimized in vitro and in vivo which and can be used in the clinic...

The advent of immune checkpoint inhibitors anti-PD-1/PD-L1 has delivered new and effective treatment options with proven clinical benefits for patients affected by metastatic melanoma. The 30-40% of treated patients experience an objective tumour regression, with a significantly prolonged survival and an improved quality of life. Here, we report a case of a 75-year-old Caucasian woman affected by a massive cutaneous metastasis from a BRAF wild-type melanoma who experienced multiple relapses after surgery and repeated electrochemotherapy treatments...
