This is the technology in which we inject minute amounts of different cancer drugs into a tumor while it is still in the body. Once the tumor is removed, doctors can examine it to see which drugs killed its cancerous cells. The new device uses several needles to inject small quantities of drugs into a tumor through the skin into a living tumor with the needles thread narrow columns of drug through the tumor once the tumor is removed, it is sliced into thin sections which can be stained for markers of drug activity.
Technology lets researchers test live tumors to see whether a small injection of a particular cancer drug (green) will work. The red marks show tumor cells succumbing to a drug. The drug is working in the top image, but not in the bottom one.
The researchers are working on a handheld disposable version of the device and recently launched a clinical study of the technology.
