• Ablation

    What is ablation of tumors?

    Ablation is a minimally invasive technique that kills tumors by heating/burning or cooling them.

    What kinds of tumors respond to ablation?

    Ablations have been most commonly used to treat liver, kidney and lung cancers. It is also used to treat certain bone lesions such as osteoid osteoma.

    How does it work?

    There are different types of ablations. The most common method used is radiofrequency ablation (RFA) that kills tumors by heating/burning. RFA is used for liver, kidney and lung tumors. Other types of ablations are cryoblation that kill tumors by cooling. It is primarily used to treat kidney cancers.

    Bassett now has microwave ablation available; a new and cutting edge technique that treats large tumors at a faster rate.

    What are the criteria for ablation?

    • Single kidney
    • Medical or surgical conditions that prevent surgery
    • Ideally used to treat tumors less than 4 cm in size
    • Liver tumors that have not responded to chemotherapy or are not suitable for surgery
    • For lung cancer, it is most effective when all cancer is localized in lungs

    Is ablation efficient and are there any advantages?

    It is very effective in treating small cancers.

    Advantages include:

    • Minimal hard to surround tissues because of local treatment
    • No large incisions needed
    • Can be repeated if necessary
    • Minimal hospital stay (usually 1 day)

    What kind of anesthesia is used?

    We usually perform ablation procedures under general anesthesia.

    What are the risks involved?

    The most common risks are similar to getting a biopsy; bleeding, infection and pain. Patients are given pain medication after the procedures.
