Oncology: can the use of ire nanoknife for pancreatic cancer result in a smaller sized tumor post procedure? how long to note size difference?

Yes: The goal of the IRE nanoknife is to reduce the size of a tumor and slow it's growth, usually for stage 3 unresectable tumors. The tumor mass may swell initially after treatment, but should get smaller over a few weeks as the dead tumor mass is resorbed. Unfortunately, the underlying tumor is not cured and how big the mass is on later scans will depend on how fast it grows back.
