treatment’s plating efficiency to the single reagent treatment one’s. Dose-response curves were created using the linear-quadratic model. 20 Combination effects were analyzed defining additivity according to Steel and Peckham. 21 For this purpose a dose-response curve was calculated that represents the course of the measured control curve at a pre-effect similar to the single reagent treatment’s effect („theoretical control-curve“). Additive effects were defined as area between the measured control curve and the theoretical one. Supraadditive effects were defined as

pulses generator Cliniporator™ (IGEA s.r.l., Carpi, Italy)). Two parallel stainless steel plate electrodes with 6 mm distance between them or 4 needle row electrodes with 4 mm distance according to the tumor size was used. Immediately after the electrochemotherapy 2 mg of the IL-12 plasmid was injected intradermally in equidistant locations around tumor nodule in two locations. 10 One high voltage pulse (amplitude to electrode distance ratio 1200 V/cm, duration 100 µs) and one low voltage pulse (amplitude to electrode distance ratio 140 V/cm, duration 400 µs) 12 were

compared with the one obtained with lower distance needles. 30 Moreover, the effect of the field in term of electroporated cells has been also verified using potato tissue tests and in vitro tests. 28 , 30 , 31 Finally, in order to verify the electroporation, the results of simple preliminary tests carried on vegetable tissue are presented. Materials and methods The prototype of the grid electrode ( Figure 2 ) is composed by a flexible support and 67 (5 or 10 mm-long) stainless steel needles that can be inserted one by one and linked to the electrical

clinics, showing a local effectiveness of up to 80% of local tumour control. 30 - 33 The antitumour effectiveness of electrochemotherapy primarily relies on increased drug uptake and platinum binding to DNA. 25 , 29 , 34 However, some effects might be attributed to immune system modulation and changes in tumour blood flow. 27 , 35 - 36 Thus far, electroporation has been used to increase antitumour effectiveness of platinum (II) analogue 3P-SK containing squarato (skv = 3,4-dioxocyclobut-1-ene-1,2-diolate) and 3-Hmpy ligands (3P-SK, [Pt(3-Hmpy) 2 (skv)]).

blood vessel via active intravasation involving epithelial-mesenchymal transition (EMT) or by passive shedding due to compromised tumor vasculature. CTCs can exist in different phenotypes- epithelial, mesenchymal or both- hybrid epithelial/ mesenchymal phenotype (hybrid E/M). CTCs can be found in the form of individual cells or cell clusters; the latter show increased metastatic potential compared to individual CTCs. Platelet-CTC interaction in the blood vessel acts as a shield against the shear stress of blood flow, immune attack and also enables the adhesion to the
