Morhard R, et al. 2017. Development of enhanced ethanol ablation as an alternative to surgery in treatment of superficial solid tumors. Scientific Reports 7:8750.
Details
The ethyl_cellulose and pure_ethanol treatments consisted of
about a quarter of the volume of the tumors, while the
pure_ethanol_16x treatment was 16x that, so about 4 times the size of
the tumors.
