Interventional Oncology Specialists In Dallas Explain How They Use Interventional Radiology (IR) To Kill Tumors
Surgical resection (removal) of cancerous tumors arguably provides the highest probability of a complete cure. However, many patients are not candidates for traditional surgery. This may be because they have such a large number of tumors that removing them all surgically is not feasible, or because the tumors are too invasive (too near or having actually invaded important arteries) to be surgically removed. External-beam radiation therapy and systemic chemotherapy can be effectively used to treat many patients who are not candidates for surgery, but these methods cannot be used in all cases, either. In this article, the best interventional radiology doctors in Dallas explain how the advanced IR procedures they specialize in can often be used to shrink or kill tumors.
General advantages of IR procedures
The interventional radiology procedures we specialize in at MTV IR can all be described as minimally-invasive, meaning that they require no large incisions, and often don’t even require general anesthesia. As a result, IR procedures are safer, don’t require long “recovery periods” because there is little to recover from, and don’t leave large, unsightly scars. More important in a way, IR procedures can often be more precise, because the use of medical imaging allows interventional oncology specialists in Dallas to guide a needle or catheter directly into the tumors themselves, localizing the effects of radiation or chemotherapy and focusing it on the tumors, increasing the treatment’s effectiveness while at the same time reducing potential side effects.
How three IR procedures we specialize in kill tumors
One procedure that is often used when a patient has tumors that are too large or too numerous to remove by surgery is chemoembolization. With this procedure, a thin catheter is inserted into the hepatic artery, and chemotherapy drugs are injected directly into the tumors themselves. This allows higher, more effective doses than are possible with systemic chemotherapy. The chemotherapy is then followed up with embolizing agents to block blood flow to the tumors and kill them. In some cases, a technique called bland embolization is used to kill or shrink the tumors, without the use of chemotherapy.
Another of the IR techniques we specialize in is called percutaneous ablation therapy, and is used for patients who have small inoperable tumors of the liver, or who cannot undergo general anesthesia. With this procedure, MTV IR surgeons use CT scans to guide a tiny needle into the tumors themselves, and then use heat generated by microwave or radiofrequency energy to kill them.
These are only a few of the specialized IR techniques that the best liver cancer doctors in Dallas use to kill tumors and fight cancer.
