In liver tumors that cannot be treated with surgery or ablation, chemoembolization is typically performed and is a standard of care worldwide. A tiny catheter is placed from a needle puncture in the groin and into the arteries feeding the tumor(s).
Highly concentrated chemotherapeutic agents and tiny particles are directly and precisely delivered to the tumors while the normal liver tissue is relatively spared. In this way, the tumor cells are exposed to the anti-tumor drug while the arteries are occluded by the particles, resulting in a dual treatment effect.
The procedure can be repeated multiple times approximately 4-6 weeks apart. The procedure usually requires an overnight stay in the hospital for observation and supportive care.
