Correction to: Cancer Gene Therapy https://doi.org/10.1038/s41417-019-0123-9, published online 18 July 2019

After publication an error was found in Table 3 of the manuscript in the columns related to gender distribution. After precise review and return to the source of the research and the collected papers, the following was found: Female (1a) = 10 (55.6%); Male (1a) = 8 (44.4%); Total N of (1a) = 18. Female (2) = 4 (20.0%); Male (2) = 16 (80.0%); Total N of (2) = 20. These modifications do not affect the results or the discussion of the manuscript, as age was not an influencing factor in this study or associated with any other parameters in the study. The amended figure accompanies this correction.
