Oncologic Interventions

In conjunction with oncologicsts, Interventional Radiology procedures provide many new and exciting frontiers to help treat patients with cancer.

Chemoembolization

Used to treat hepatic tumors and metastases.

Chemoembolization Chemoembolization chemoembolization

A small microcatheter is irected into the selective arterial branch of the tumor to be treated and a dose of chemotherapy is delivered in a highly focused area.

  • Patients are followed up by CT imaging to assess tumor size reduction.

  • As the tumor recurs over time, it can be retreated.

Radiofrequency Ablation (RFA)

Used to treat hepatic, renal, or lung tumors.

  • Using ultrasound or CT guidance, a probe is inserted percutaneously into the tumor and metal “prongs” are advanced into the mass.  The tumor is then super heated causing tumor lysis.

  • Patients are followed up by CT imaging to assess tumor size reduction.
  • As the tumor recurs over time, it can be retreated.

Therasphere Ablation*

Used to treat hepatic tumors and metastases.

  • Angiography of the hepatic system is first undertaken to study the arterial map supplying the tumor and adjacent organs.  Vessels close to the site of tumor to be treated are initially embolized to prevent reflux into the stomach or pancreas.

  • Radioactive Yittrium-90 coated beads are then injected into the site of the tumor resulting in tumor lysis.
  • Patients are followed up by CT imaging to assess tumor size reduction.
  • As the tumor recurs over time, it can be retreated.
