Objective: obtaining electrical resistivity curves for cervical tissues in invasive cervical cancer.
Methodology: a tissue impedance meter was used (MK 3.5 Electrical Impedance Spectroscopy, single channel system) in this cross-sectional study of invasive cervical cancer patients; it led to calculating the tissues’ transfer impedance by means of a pencil probe incorporating four gold electrodes.
Results: 102 measurements were made and resistivity curves for cervical tissue were obtained in 18 women aged 46 to 72 (56±9, mean ± SD). These tissues presented a special resistivity curve for invasive cervical cancer, average resistivity parameters being (R0 = 4.35 ± 2.26 [Ω-m] and R∞ = 1.41 ± 0.57 [Ω-m]). Resistivity values for those estimations (R = 4.35 ± 2.26 [Ω-m] and S = 2.44 ± 1.11 [Ω-m]).
Conclusion: electrical impedance spectroscopy presented different patterns for invasive cervical cancer tissue and healthy tissue.
