MIAMI BEACH, Fla.--(BUSINESS WIRE)--Bathing tumor-ridden livers in chemotherapy increases the length of time certain cancer patients survive without progression of the disease, according to Phase III trial results being presented at the 3rd annual Symposium on Clinical Interventional Oncology (CIO), in collaboration with the International Symposium on Endovascular Therapy (ISET). Minimally invasive chemosaturation delivers high doses of chemotherapy into the liver to more effectively battle tumors while limiting toxicity to the rest of the body.
