“…Whilst these six individual studies were generally of a smaller malignant tissue sample size, all six studies were able to show that various bioimpedance parameters could be used to distinguish malignant from normal tissue. The studies of gastric adenocarcinoma, renal cell carcinomas, various thyroid malignancies and squamous cell skin cancer all showed malignant tissue to have lower impedance and/ or resistivity/permittivity than normal [55][56][57][58], whilst the colorectal and oesophageal studies showed higher impedance with malignant lesions compared to normal [58][59][60]. Additionally, the colorectal study showed that in two previously malignant lesions that had shown complete response to chemoradiotherapy, the impedance measurements appeared to be similar to that of normal colorectal tissue [58].…”

“…Six other independent studies looked at the effects of the malignant process on the electrical conductivity of various tissue types, four of which were on in vivo specimens. The 6 individual tissue types included thyroid malignancies, squamous cell carcinomas of the skin, oesophageal adenocarcinoma and squamous cell carcinoma, gastric adenocarcinoma, colorectal adenocarcinoma and renal cell carcinoma [55][56][57][58][59][60]. Whilst these six individual studies were generally of a smaller malignant tissue sample size, all six studies were able to show that various bioimpedance parameters could be used to distinguish malignant from normal tissue.…”

Background Electrical impedance technology has been well established for the last 20 years. Recently research has begun to emerge into its potential uses in the detection and diagnosis of pre-malignant and malignant conditions. The aim of this study was to systematically review the clinical application of electrical impedance technology in the detection of malignant neoplasms. Methods A search of Embase Classic, Embase and Medline databases was conducted from 1980 to 22/02/2018 to identify studies reporting on the use of bioimpedance technology in the detection of pre-malignant and malignant conditions. The ability to distinguish between tissue types was defined as the primary endpoint, and other points of interest were also reported. Results 731 articles were identified, of which 51 reported sufficient data for analysis. These studies covered 16 different cancer subtypes in a total of 7035 patients. As the studies took various formats, a qualitative analysis of each cancer subtype’s data was undertaken. All the studies were able to show differences in electrical impedance and/or related metrics between malignant and normal tissue. Conclusions Electrical impedance technology provides a novel method for the detection of malignant tissue, with large studies of cervical, prostate, skin and breast cancers showing encouraging results. Whilst these studies provide promising insights into the potential of this technology as an adjunct in screening, diagnosis and intra-operative margin assessment, customised development as well as multi-centre clinical trials need to be conducted before it can be reliably employed in the clinical detection of malignant tissue.

Conventional methods of electrobioimpedance imaging are not suited for adequate visualization of the skin electrical impedance landscape (SEL) because they do not provide high spatial resolution at large enough area of view. The skin electrodynamics introscopy (SEI) enabled dynamic spectral imaging of the SEL at 32 × 64 mm area with 1 mm spatial resolution. The focus of the study was to investigate the SEL distinguishing features between early and advanced-stage cancer at the model object of melanoma and its satellite. The analysis of the test-induced SEL metamorphoses was carried out at the periods of blood-stop and blood-restoration. It was found that the young tumor could be reliably visualized and distinguished by its antiphase hypoxia-induced response as compared to that of the advanced one. In response to the blood-restoration, an appearance of newly formed SEL clusters pointed out apparently at vascular abnormalities associated with the tumor. Similar SEL clusterization can be supposedly expected in response to any other test factors which affect cell permeability or/and blood viscosity. The proposed approach might be useful for more thorough mapping and staging malignancies.
