Three different burst lengths (10, 50, and 86 ms) were employed to treat the 9L brain tumour. (A) Three weeks of the shorter burst lengths (10 and 50 ms) treatment did not inhibit the tumour from growing as the 86 ms burst length. In addition, 50 ms burst length has slightly slowed the tumour growth, but no difference was found between these two parameters. (B) No significant difference in survival was detected between 10 and 50 ms. In contrast, 86 ms burst length resulted in a 100% survival rate.
