Gnawkz: "Hey Dok, the Choi system measures 2 criteria separately ... either there is a 10% reduction in tumor size OR A 15% reduction in overall tumor density. The 2nd measurement system was included to account for treatment that affect tumors from the inside out.

DCVax would fall under the latter category."

That sounds reasonable. As long as they include the hollowing as part of the density change. Get the new volume by subtracting the inner and outer volumes, then also multiply by tissue density based on tissue samples.
