36. Radiologic interventions in tumor treatment (Tumor ablation techniques. Selective cytostatic treatment, chemoembolization).
- Transarterial chemoembolisation therapy (TACE)
- Combination of transcatheter embolization and supplying chemotherapeutical drug-eluding beads directly to the tumor with a catheter
- Tumor is both embolised and chemo’d
- Used for liver cancer
- Radiofrequency ablation (RFA)
- US or CT guided
- Generally used for small tumors
- Procedure
- A needle-like radiofrequency probe is placed inside the tumor
- Radiofrequency waves passing through the probe increases the temperature in the tumor -> destruction
- Microwave ablation (MWA)
- 900 MHz – 300 GHz
- US or CT guided
- Procedure
- A needle-like microwave probe is placed inside the tumor
- Microwaves are created from the needle
- Microwaves heat the tumor -> destruction
