Subsequently to the publication of the above article, the authors have realized that Fig. 3 on p. 6, showing the results of bioluminescence imaging of U87 and U373 cells after applying tumor‑treating fields for 72 h, was published containing an erroneous image. Essentially, the data analysis panel for the U87 / U87TTF experiment was inadvertently copied across for the U373 / U373TTF experiment for the '75% Duty' experimental condition. The revised version of Fig. 3, now showing the correct data analysis panel for the '75% Duty' U373 / U373TTF experiment, is shown below. The authors confirm that the error made in the presentation of Fig. 3 did not adversely affect the conclusions reported in this paper, and they are grateful to the Editor of International Journal of Oncology for granting them this opportunity to publish a Corrigendum. All the authors agree to the publication of this Corrigendum; they also apologize to the readership for any inconvenience caused.
