Predicting patients at risk for pain associated with electrochemotherapy - Danish National Research Database-Den Danske...
BACKGROUND: Electrochemotherapy describes the use of electric pulses to enhance chemotherapy uptake, and has proven highly efficient in treating cutaneous metastases. Patients referred for electrochemotherapy present with diverse clinical pictures, from multiple small lesions to large, ulcerated lesions. Post-electrochemotherapy pain has been observed in some patients. The objectives of this study were to evaluate pain scores before and after electrochemotherapy, and to investigate if patients at risk of post-procedure pain could be identified. METHODS: Seven cancer centres in the International Network for Sharing Practices on Electrochemotherapy (INSPECT) consecutively and prospectively reported to a common database. Electrochemotherapy consisted of intratumoural or intravenous injection of bleomycin, followed by delivery of electric pulses in local or general anesthesia. RESULTS: Of 121 patients 39% had metastatic melanoma, 18% squamous cell carcinoma, 16% breast cancer, 13% basal-cell ...

TY - JOUR. T1 - Efficient palliation of haemorrhaging malignant melanoma skin metastases by electrochemotherapy. AU - Gehl, J.. AU - Geertsen, P. F.. PY - 2000/12/1. Y1 - 2000/12/1. N2 - Electric pulses can cause transient permeabilization of cell membranes (electroporation) and this can be utilized to increase the uptake of chemotherapy (electrochemotherapy). Preclinical studies have shown that in vivo electroporation causes transient shut down of blood flow both in normal and, in particular, malignant tissues. We report the successful palliation of a malignant melanoma patient with bleeding skin metastases using electrochemotherapy. In an on-going study of combined electrochemotherapy and low dose interleukin-2, one patient with bleeding skin metastases was included. Nine skin metastases, of which seven were ulcerated, were treated. After intratumoral bleomycin injection, needle electrodes with two arrays 4 mm apart were inserted into the tumours. Eight square wave electric pulses each 99 μs ...
Electrochemotherapy - Wikipedia
Electrochemotherapy is a type of chemotherapy that allows delivery of non-permeant drugs to the cell interior. It is based on the local application of short and intense electric pulses that transiently permeabilize the cell membrane, thus allowing transport of molecules otherwise not permitted by the membrane. Applications for treatment of cutaneous and subcutaneous tumors have reached clinical use by utilizing drugs such as bleomycin or cisplatin). Electrochemotherapy with bleomycin was used to treat a patient for the first time in 1991 at the Institute Gustave Roussy in France, while electrochemotherapy with cisplatin was used to treat for the first time in 1995 at the Institute of Oncology, Ljubljana, Slovenia. Since then, more than 4000 patients were treated with electrochemotherapy all over the world (Australia, Austria, Belgium, Bulgaria, Denmark, France, Germany, Greece, Hungary, Ireland, Italy, Japan, Mexico, Nicaragua, Poland, Portugal, Slovenia, Spain, Sweden, UK, USA). Recently, new ...

Treatment of Liver Metastases With Electrochemotherapy - Full Text View - ClinicalTrials.gov
The study will be conducted on patients with colorectal cancer with synchronous or metachronous liver metastases. Included will be 10-15 patients.. Predominantly, patients with synchronous metastases will be included into the study. These patients present liver metastases at the time of primary tumor resection. Electrochemotherapy will be performed on one metastasis not more than 3 cm in largest diameter at the time of the primary tumor operation, but patients have to have at least 2 to 8 metastases. These metastases will be aimed to be resected in the following operation. It is a standard procedure that liver metastases are resected 2-3 months after the primary tumor resection, in the meantime they are on standard chemotherapeutic protocol (FOLFOX, FOLFIRI, Capecitabine). Only in the case of solitary metastasis smaller than 3 cm in diameter, it is resected during the resection of the primary tumor. In the study additional antitumor effectiveness of electrochemotherapy to other treatment ...
Electroporation-based treatments in minimally invasive percutaneous, laparoscopy and endoscopy procedures for treatment of deep...
Electroporation (EP) techniques, used alone (Irreversible Electroporation, IRE) or in combination with anti-cancer drugs (Electrochemotherapy, ECT), have been shown to be effective in the treatment of several types of cancers. The efficacy of ECT and IRE is well demonstrated for the treatment of non-superficial tumor metastases, and it depends on the applied electrical parameters. Particularly, ECT is an effective local therapy that uses electroporation to enhance the cytotoxic effect of bleomycin or cisplatin injected intravenously or intratumorally. Pre-clinical investigations to test alternative anti-cancer drugs, explore new combinations of treatment modalities, and evaluate different sets of pulse protocols for effective tissue electroporation, are ongoing. Further ECT developments include the treatment of deep-seated tumors with percutaneous, laparoscopy, and endoscopy approaches, with the aim of establishing a less invasive approach. ECT is highly effective in the treatment of tumors of ...
Long-lasting response to electrochemotherapy in melanoma patients with cutaneous metastasis | BMC Cancer | Full Text
Treatment of early and multiple cutaneous unresectable recurrences is a major therapeutic problem with around 80% of patients relapsing within 5 years. For lesions refractory to elective treatments, electrochemotherapy (ECT) involving electroporation combined with antineoplastic drug treatment appears to be a new potential option. This study was undertaken to analyze the short- and long-term responses of lesions treated with ECT with intravenous injection of bleomycin in melanoma patients with in-transit disease or distant cutaneous metastases. Between June 2007 and September 2012, 60 patients with relapsed and refractory cutaneous melanoma metastases or in-transit disease underwent 100 courses of ECT with intravenous injection of bleomycin. Response to treatment was evaluated three months after ECT. A long-lasting response was defined as no cutaneous or in-transit relapse after a minimum of six months. Three months after ECT, a complete response was observed in 29 patients (48.4%), a partial response

Modeling the positioning of single needle electrodes for the treatment of breast cancer in a clinical case | BioMedical...
Breast cancer is the most common cancer in women worldwide. The World Health Organization [1], reported that cancer is a leading cause of death [2] and that breast cancer is the second most common cause of cancer death in women, with a 521000 deaths in 2012. Typical treatments are based on surgical procedure (lumpectomy or mastectomy), often the surgical removal is combined with radiation therapy, chemotherapy or hormone therapy as an adjuvant therapy [3]. The invasiveness of the surgical technique has lead to an interest in new types of minimally invasive treatments such as radiofrequency ablation, cryosurgery and irreversible electroporation [4-9].. In these last years, electrochemotherapy (ECT) has been evaluated as a new possible technique to treat different kind of tumors [10-13].. Electrochemotherapy (ECT) is a technique that combines chemotherapy (insertion of non permeant or low permeant chemotherapeutic drugs with high cytotoxicity) with local application of pulsed electric fields to ...
A Novel Scheme To Enhance Local Electric Fields Around Metal Nanostructures - Redorbit
Enhanced local electric fields are predominant in nonlinear optical properties, particularly in surface-enhanced Raman scattering (SERS), which is a sensitive technique used for the detection of trace amounts of chemicals. Analysis of the electric fields around nanostructures indicates that they can provide a basic foundation to obtain greater SERS intensity. Professor ZHANG Zhongyue and his group from the College of Physics and Information Technology at Shaanxi Normal University have proposed a novel scheme to enhance the local electric fields around nanostructures. The scheme is based on manipulation of the incident wave to allow the superposition of the electric fields of multiple beams of light to work as the excitation source for the electrons in the nanostructures, and larger electric fields are thus excited around the nanostructures. Their work, entitled Enhancing the electric fields around the nanorods by using metal grooves, was published in SCIENCE CHINA Physics, Mechanics & ...

Radiological findings of porcine liver after electrochemotherapy with bleomycin in: Radiology and Oncology Volume 53 Issue 4 ...
Radiologic findings after EP/ECT of large hepatic vessels and hepatic parenchyma were characterized in a porcine model, which was selected due to anatomical and physiological similarities with the human liver.1, 33 The results showed decreased perfusion in the treated area. This finding was an anticipated result since EP/ECT induces a local blood flow modifying effect or vascular lock characterized by the vasoconstriction and increased wall permeabilization of small blood vessels. The effect on perfusion is shorter in EP compared to that in ECT and shorter in healthy compared to tumor tissue, which is known as the vascular disrupting effect. Chemotherapeutic drugs are cytotoxic to endothelial cells, especially neoplastic endothelial cells, and this effect prolongs decreased perfusion.34, 35, 36, 37, 38, 39, 40, 41 In our case, there was no difference between EP and ECT, and no vascular disrupting effect was observed in healthy hepatic parenchyma28, which confirms that bleomycin at the doses ...
Electrochemotherapy of colorectal liver metastases - an observational study of its effects on the electrocardiogram |...
The results of our study indicate that intra-abdominal surgery involving ECT of colorectal liver metastases was associated with only minor and clinically irrelevant changes in functioning of the heart detected in early post-operative care and as such presented no life threat for the patients. No major changes in functioning of the heart such as rhythm changes (i.e., increased induction of abnormal heartbeats, ventricular tachycardia or fibrillation) or pathological morphological changes (e.g., ST segment changes) that would suggest myocardial ischemia were found in ECG signals.. According to the literature, surgery and anesthesia produce a stress response characterized by increased sympathetic and hormonal activity which may predispose the patient to arrhythmias [30]. Post-operative arrhythmias are thus quite common and affect about 7% of patients that underwent major non-cardiothoracic surgery. Post-operative arrhythmias occur more commonly in older patients, most often in the first four days ...

Diagnosis and treatment of Kaposis sarcoma: European consensus-based interdisciplinary guideline (EDF/EADO/EORTC). - Immunology
Kaposis sarcoma (KS) is a multifocal neoplasm of lymphatic endothelium-derived cells infected with human herpesvirus 8. Four clinical subtypes are distinguished: the classic, the endemic, the epidemic subtype in HIV positive patients and the iatrogenic subtype. The diagnosis is primarily based on clinical features and confirmation by histology with immunohistochemistry. Cutaneous distribution and severity, mucosal, nodal and visceral involvement depend on the type of KS with in general indolent behaviour and chronic evolution in the classic subtype and the more severe forms in iatrogenic or epidemic subtypes. Management should aim at achieving disease control. For localised lesions, several local therapies have been developed without randomised trial comparisons. Radiotherapy, intralesional chemotherapies and electrochemotherapy have high response rates. Topical treatments-imiquimod or topical 9-cis-retinoid acid-can also be used. Systemic treatments are reserved for locally aggressive extensive and

Bleomycin is a treatment for a number of types of cancer. Bleomycin is a type of antibiotic that is poisonous to cells. It binds to the cancer cells DNA so that the cells cant divide or grow. Electrochemotherapy is a cancer treatment. The definition of therapeutic window of lectrochemotherapy is based on the observed responses of the tumors that were treated at different time points after the drug injection. To refine the method, thorough knowledge is needed about the pharmacokinetics and pharmacodynamics of bleomycin, which would base on sensitive analytical method. This method was not available until recently. The aim of the study is therefore to determine pharmacokinetics and pharmacodynamics of bleomycin in patients treated with electrochemotherapy, for optimization of the treatment ...

Electroporation as a delivery method is increasingly important in gene therapy, not only in vivo but also in in vitro experimental systems. Different applications of gene electrotransfer require high viability of cells and high transfection efficiency of gene electrotransfer. It was already demonstrated that the addition of fetal bovine serum (FBS) immediately after gene electrotransfer leads to improved cell survival and transfection efficiency. Therefore, the aim of the study was to determine whether prolonged incubation of cells in FBS, for more than standard 5 min, can lead to increased transfection efficiency and improved cell survival. Different murine melanoma and murine and human endothelial cell lines were transfected with plasmid encoding green fluorescent protein and then incubated for different periods of time in FBS (5-30 min). Transfection efficiency was determined by flow cytometry and fluorescence microscopy and cell survival by cell viability assay. Prolonged incubation of cells ...
Mapping of bionic array electric field focusing in plasmid DNA-based gene electrotransfer | Gene Therapy
Molecular medicine through gene therapy is challenged to achieve targeted action. This is now possible utilizing bionic electrode arrays for focal delivery of naked (plasmid) DNA via gene electrotransfer. Here, we establish the properties of array-based electroporation affecting targeted gene delivery. An array with eight 300 μm platinum ring electrodes configured as a cochlear implant bionic interface was used to transduce HEK293 cell monolayers with a plasmid-DNA green fluorescent protein (GFP) reporter gene construct. Electroporation parameters were pulse intensity, number, duration, separation and electrode configuration. The latter determined the shape of the electric fields, which were mapped using a voltage probe. Electrode array-based electroporation was found to require ~100 × lower applied voltages for cell transduction than conventional electroporation. This was found to be due to compression of the field lines orthogonal to the array. A circular area of GFP-positive cells was created when

Patent US20070043345 - Tissue ablation with irreversible electroporation - Google Patents
A new method for the ablation of undesirable tissue such as cells of a cancerous or non-cancerous tumor is disclosed. It involves the placement of electrodes into or near the vicinity of the undesirable tissue through the application of electrical pulses causing irreversible electroporation of the cells throughout the entire area of the undesirable tissue. The electric pulses irreversibly permeate the cell membranes, thereby invoking cell death. The irreversibly permeabilized cells are left in situ and are removed by the body immune system. The amount of tissue ablation achievable through the use of irreversible electroporation without inducing thermal damage is considerable.

Irreversible Electroporation Therapy for the Treatment of Spontaneous Tumors in Cancer Patients
Irreversible electroporation is a minimally invasive technique for the non-thermal destruction of cells in a targeted volume of tissue, using brief electric pulses, (~100 µs long) delivered through electrodes placed into or around the targeted region. These electric pulses destabilize the integrity of the cell membrane, resulting in the creation of nanoscale defects that increase a cells permeability to exchange with its environment. When the energy of the pulses is high enough, the cell cannot recover from these effects and dies in a non-thermal manner that does not damage neighboring structures, including the extracellular matrix. IRE has been shown to spare the major vasculature, myelin sheaths, and other supporting tissues, permitting its use in proximity to these vital structures. This technique has been proposed to be harnessed as an advantageous non-thermal focal ablation technique for diseased tissues, including tumors. IRE electric pulses may be delivered through small (ø ≈ 1 mm) ...

PurposeNumerical simulations are used for treatment planning in clinical applications of irreversible electroporation (IRE) to determine ablation size and shape. To assess the reliability of simulations for treatment planning, we compared simulation results with empiric outcomes of renal IRE using computed tomography (CT) and histology in an animal model.MethodsThe ablation size and shape for six different IRE parameter sets (70-90 pulses, 2,000-2,700 V, 70-100 µs) for monopolar and bipolar electrodes was simulated using a numerical model. Employing these treatment parameters, 35 CT-guided IRE ablations were created in both kidneys of six pigs and followed up with CT immediately and after 24 h. Histopathology was analyzed from postablation day 1.ResultsAblation zones on CT measured 81 ± 18 % (day 0, p ≤ 0.05) and 115 ± 18 % (day 1, p ≤ 0.09) of the simulated size for monopolar electrodes, and 190 ± 33 % (day 0, p ≤ 0.001) and 234 ± 12 % (day 1, p ≤ 0.0001) for bipolar electrodes. ...

Cutaneous antiangiogenesis by gene electrotransfer
| DIAL.pr - BOREAL
eng] Despite the discovery of novel inhibitors of tumor angiogenesis, protein-based antiangiogenic cancer therapy suffers some limitations that antiangiogenic gene therapy could overcome. We investigated the effect on tumor growth and metastasis of three antiangiogenic plasmids administered by two intratumoral electrotransfers. Plasmids encoding recombinant disintegrin domain of ADAM-15 (RDD), thrombospondin 1 (TSP-1) and the soluble isoform of the VEGF receptor 1 (sFlt-1) were injected into B16F10 melanoma-bearing C57BL/6 mice followed by electroporation. Tumor volume was measured daily using a digital caliper. Metastasis was monitored by in vivo bioluminescence after surgical removal of the primary luciferase-encoding tumor 5 days after intratumoral electrotransfer. Markers of vascularization and cell proliferation were quantified by immunohistochemistry. All the plasmids induced a significant inhibition of tumor growth, doubling of mean survival time and long term survivors (~40% vs 0% in ...

OSA | Optical scattering and absorption by branched chains of aerosols
We utilize the Volume Integral Equation Formulation (VIEF) and the method of moments to calculate the electromagnetic scattering and absorption of aerosol particles with branched-chain structures. Two kinds of polarization of the incident electromagnetic wave were considered: the cross- and end-fire polarizations. The numerical results of internal electric field distribution, absorbed power, and extinction and scattering cross sections, obtained from the VIEF, show excellent agreement with the Mie theory for the special case of spherical particles. Comparison between the results of the VIEF and Iterative Extended Boundary Condition Method for very long oriented (elongated) chains of particles also showed good agreement. After validating the accuracy of the VIEF, the absorption characteristics of three branched-chain structures simulated from microscopic pictures of coagulated smoke aerosol particles were calculated. Results showed that the ratio of absorption in the two polarization cases, ...

Nelinearni dinamički model tkiva podvrgnutog elektropermeabilizaciji | Repozitorij FER-a
The aims of this study were: (i) to develop mathematical models of electric and related thermal phenomena in tissue exposed to electric pulses that are used for in vivo electropermeabilization and gene electrotransfer, and (ii) to analyze the possibility that voltage and current measurement during pulse delivery can be used to actively monitor and predict the extent of tissue electropermeabilization. The proposed models are based on the solution of appropriate partial differential equations for electric potential and temperature distribution in tissue using finite-element method (3D FEM). For two configurations of electrodes (parallel plates and two needles) and different pulse delivery protocols, including short high-voltage permeabilizing pulses and long low-voltage electrophoretic pulses, we performed numerous simulations in order to quantify the influence of tissue electrical conductivity (including anisotropy, nonlinearity and temperature dependence), pulse parameters (amplitude, number, ...

Cutaneous metastasis: a rare phenomenon of colorectal cancer
Cutaneous metastases from colorectal cancer are extremely rare and generally appear several years after diagnosis or resection of the primary tumor. Although this phenomenon is uncommon, it is very important and often indicates a poor prognosis. We present a case of a 76-year-old female patient with multiple cutaneous metastatic nodules on the back, just 1 month after resection of rectal cancer. Unfortunately, the patient gave up the follow-up treatment due to her age and poor physical condition; she died 3 months later. In view of its rarity of occurrence and lack of experience in treatment, we reviewed the literature and report as follows. ...

Minneapolis is negotiating agreements with local electric and natural gas utilities that seek more commitment to clean energy, a year after controversial debates over the city starting its own municipal utility.. City leaders are renewing 20-year-old franchise agreements, set to expire in December, that give Xcel Energy and CenterPoint Energy access to public right of way in exchange for millions of dollars in fees. The new arrangements are expected to be much shorter in duration, accompanied by a separate partnership that would have utilities work with the city to meet its greenhouse gas reduction targets.. Negotiations could be completed as early as in September, though utility and city officials have declined to offer many details.. Council Member Cam Gordon said he expects that the results will fall in line with an environmental consultants recommendations in February. Given the restrictions state laws put on what cities can require in franchise agreements, the report advised Minneapolis to ...

OSA | Asymptotic analysis of dielectric coaxial fibers
Using an asymptotic analysis, we analytically calculate the dispersion and the field distribution of guided modes in an all-dielectric coaxial fiber. We compare the analytical results with those obtained from numerical calculations and find excellent agreement between them. We demonstrate that both the Bragg reflection and the total internal reflection play important roles in providing confinement and determining the dispersion characteristics of the coaxial fiber modes.. © 2002 Optical Society of America.
