Can Radiofrequency Ablation Cure Liver Cancer?

Radiofrequency abaltion (RFA) is a minimally invasive procedure that has shown promising results in the treatment of liver cancer, particularly for smaller tumors. For tumors measuring 3 cm or less, RFA can potentially offer a curative outcome. This is because the thermal energy used during the procedure can effectively destroy all cancerous cells within the targeted area.

During RFA, a specialized needle is inserted into the tumor under imaging guidance. Once in place, high-frequency electrical currents are passed through the needle to generate heat, which destroys the tumor cells. When the tumor is small, this heat can evenly distribute and completely eliminate the cancerous tissue.

However, when dealing with larger tumors, the effectiveness of RFA may decrease. Heat conduction becomes less efficient, which can lead to incomplete ablation and potential tumor residue. Additionally, tumors located near large blood vessels may also be more challenging to treat, as the blood flow can dissipate heat and reduce the overall effectiveness of the procedure.

In cases where residual cancer cells are detected after the initial treatment, repeat RFA sessions can be performed to target remaining cancer cells. While RFA may not be curative for larger tumors, it can still play a valuable role in managing the disease by reducing tumor burden and alleviating symptoms.

In summary, RFA is a highly effective curative option for small liver tumors, while for larger tumors it serves more as a palliative treatment to control disease progression. Patients considering RFA should consult with their healthcare provider to determine if they are suitable candidates based on tumor size, location, and overall health status.
