The Novel Concept and Treatments for Cancer

Vascular Interventional Therapy

Angiogenesis

Like normal body cells, cancerous cells are fed by blood vessels. A physician typically inserts a catheter at a point in the groin to access the femoral artery, although he or she may sometimes use an arm artery. While monitoring the location of the catheterusing fluoroscopy, a type of DSA, the physician steers the catheter through the arterial system to the tumor. Eventually, the physician delivers cancer treatment through the catheter directly to the tumor. The physician may also use long, thin needles to deliver treatment to cancer tumors.

Indication

The following types of cancer therapy are administered using interventional techniques:

Transarterial chemoembolization(TACE).
Embolization materials and chemical drugs are injected through a catheter that is placed directly into an artery that supplies a cancer tumor. TACE appears to hold promise especially for aggressive liver cancers.

Transarterial Chemical infusion(TACI).
Using the modality, chemical drugs are directly infused into tumor to kill cancerous cells. The modality is adaptable for treatment of a lot of cancers.

Advantages

Interventional therapy deposits chemotherapy drugs directly into the tumor, sparing healthy tissue.Therefore, a physician can safely use higher doses of these drugs.

Requires fewer anesthetics;
Causes fewer traumas to the body;
Typically causes less pain and few general side effects;
Results in a shorter hospital stay;
Requires a shorter recovery period

Possible Complications

The side effects and complications of interventional therapy depend upon the reason for the procedure and location of interventional treatment. In general, interventional therapy is safe and commonly associated with only minor side effects, including:

Low-grade fever
Nausea
Pain
The most serious risk is that an interventional procedure may cause hemorrhage, or bleeding, and, very rarely, death

Physicians deliver therapy through the blood vessels leading to a cancer tumor
