About Minimally Invasive cancer treatment options
What is interventional oncology?
Interventional oncology is the practice of providing minimally invasive, targeted treatment of cancer. Using image guidance and the most current techniques, RIA Endovascular physicians — specially trained, board-certified and fellowship trained interventional radiologists called interventional oncologists — treat cancerous tumors without medicating or affecting other parts of the body. We work with patients and physicians locally, nationally and internationally.
There are four modalities used to treat cancer
Interventional oncology is one of four modalities in a multidisciplinary team approach to the treatment of cancer and cancer-related disorders.
The others are:
- Medical Oncology
- Surgical Oncology
- Radiation oncology
Interventional procedures are minimally invasive, so where possible, patients appreciate this approach.
A small (percutaneous) cut used to access the affected organ, so recovery time and chance of infection are minimized.
Why Are Minimally Invasive Procedures Preferred for Treating Cancer Patients?
What are the two minimally invasive approaches used by interventional radiologists to treat cancer?
Interventional oncology uses two approaches:
- Local Treatments
- — Specific tumors are treated directly. Local therapies involve placing a needle or probe directly into the tumor. The tumor can then be reduced or eradicated by targeted modalities such as cryo (freezing), radio frequency, or microwave. This can be done in the lung, liver, bone, kidney, adrenal gland and other sites.

- Thermal Ablation – using extreme heat or cold
- Microwave ablation – heat
- Radiofrequency Ablation (RFA) – heat
- Cryoablation – freezing
- Electrical Disruption
- Irreversible electroporation (IRE) – This electrical disruption techniques is often referred to as nanoknife
- Regional Therapies
- — The region of an organ containing multiple lesions is treated. Regional therapies involve injecting a substance such as radioactive particles and-or chemotherapy particles into a specified area to treat multiple tumors, also referred to as lesions.
Such minimally invasive (non-surgical) therapies include:
- Yttrium-90 radioembolization
- Also known as selective internal radiation therapy or Y-90
- – Chemo-laden inert beads are placed to block the blood supply to the tumors while delivering regionally specific chemotherapy to the region of the tumor.
- Transarterial chemoembolization (TACE)
- – A procedure using small embolic particles coated with chemotherapeutic agents (called drug-eluting beads) that are selectively injected selectively into the artery directly supplying the tumor to both restrict the tumor’s blood supply and deliver targeted chemotherapy
- Percutaneous hepatic perfusion (PHP)
Other Interventional Radiology Procedures and Treatments
Other adjunctive procedures include drainage procedures, such as long-term catheters used to drain excess fluid from around the abdomen(paracentesis) and from the lungs (thoracentesis), and infusion port placement and removal are performed.
