Radiofrequency Ablation and Microwave Coagulation Therapy – Destroying Liver Cancer without Surgery
Radiofrequency Ablation and Microwave Coagulation Therapy -These minimally invasive approaches are showing encouraging results in many patients diagnosed with liver cancer, with very little rate of recurrence. Shorter hospital stay, faster recovery and insignificant side effects are why these latest approaches score over the conventional open approach surgery that requires a long incision and subsequently a long recovery period.
Guided by real-time images on the computer, these procedures destroy the cancer cells in the liver by generating enormous amount of heat. Since the penetrating energy is focused and accurate there is negligible damage to the neighboring healthy cells eliminating the possibility of collateral damage. Since liver cancers have a high recurrence rate even after traditional surgery, RFA procedure is useful to destroy resistant, deep seated, inoperable or recurrent cancers. It also helps to avoid liver transplant if the cancerous lesion is very small. It is a repeatable procedure and has long term survival rates. RFA in combination with trans-catheter arterial chemoembolization (TACE) is also an effective treatment for inoperable hepatic tumors.
The RFA process involves the insertion of a needle into liver using image guided technology near the site of tumor. Once in place, high intensity radiofrequency energy is transmitted through it which generates a large amount of heat that completely destroys the cancer cells. The procedure also works when the surgery has been done once and can’t be done for the second time but the tumor has reoccurred.
