Study Arms:
- RFA group (Type: EXPERIMENTAL): A percutaneous (utlrasound-guided) radiofrequency ablation (RFA) of the tumor will be performed by the radiologist under general anesthesia. Immediately after, excision of the tumor with appropriate margin will be accomplished.
- Control group (Type: NO_INTERVENTION): Normal excision of the tumor according to the protocol
