Is Radiofrequency Ablation Effective for 2cm Liver Cancer?

For early-stage liver cancer measuring less than 2cm, treatment can be successfully achieved through either surgical resection or radiofrequency ablation (RFA). RFA involves inserting a needle directly into the center of the tumor, where heat, microwave energy, or electrical currents are used to destroy cancerous tissue. This method typically creates a destruction radius of about 4–5cm, making it highly effective for tumors around 2cm in size, provided the needle is accurately placed.

Studies have shown that patients who undergo RFA treatment for small liver tumors can achieve a 10-year survival rate of over 74%, which is comparable to surgical outcomes. After the procedure, regular follow-up every three months is recommended to monitor for recurrence and ensure the effectiveness of the treatment.

Moreover, radiofrequency ablation is particularly beneficial for patients with recurrent liver cancer. In such cases, repeat surgery may not be feasible due to various factors, including the patient's overall health or the location of the recurrence. Ablation offers a minimally invasive, effective, and straightforward alternative, often becoming the preferred treatment for recurrent cases.

This therapy is well-tolerated, has fewer complications, and allows for quicker recovery compared to traditional surgery. As a result, RFA has become a cornerstone in the management of small and recurrent liver tumors, especially in patients who are not ideal candidates for more invasive procedures.
