Our nanoknife treatment is primarily used for pancreatic cancer or cancer that has metastasized to the pancreas. Then the other two treatments, like cryotherapy and seed implantation, also depend on where the metastases are. If it's in a cavity organ, like a bowel, a bladder, those cavity organs. These two treatments are not suitable due to the possibility of causing perforation, so these areas are not suitable for treatment. However, metastases of other organs are usually practicable. For multiple sites of metastasis, we need to combine with some other treatments. It is not enough to do these few minimally invasive treatments alone. We may need to add interventional therapy, immunotherapy and targeted therapy. A combination of therapies can lead to a better outcome for killing tumors.
