36. Radiologic interventions in tumor treatment (Tumor ablation techniques. Selective cytostatic treatment, chemoembolization).

From greek.doctor
  • 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
      • Liver
      • Lung
      • Pancreas
    • 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
