Breast cancer is a major source of morbidity and mortality in the elderly population and the number of patients will increase by 30% in future decades. Surgery and endocrine therapy could be considered as the standard treatment in elderly breast cancer patients, but anaesthesia for surgery requires a specific approach taking into account physiological and psychological alterations secondary to ageing. In cases with major alterations of performance status, percutaneous radiofrequency ablation (RFA) could be substituted for the surgical treatment. The aim of the current study is to evaluate the efficacy and feasibility of this technique. Five tumours in four consecutive patients (aged 79–82 years) contraindicated for surgery with symptomatic cT1-2N0M0, positive oestrogen receptor status, low grade were treated by percutaneous radiofrequency–lump ablation under local analgesia, using percutaneous ultrasound guidance. Thermal lesions were produced with RF power 30 W, at a frequency of 500 kHz. Ultrasound-guided percutaneous biopsy of the RF treated breast was performed during the follow-up. We report a successful RFA lump ablation experience in the treatment of four tumours (4/5). One local recurrence occurred within 4 months after RFA. The other biopsies taken during the follow up showed all fat necrosis within the oil cyst and no malignant cells. One abscess occurred at 9 months within the treated area. After a mean follow up of 29.4 months, all the patients are still alive without any other signs of recurrence or metastases. Ultrasound-guided percutaneous RFA is safe and feasible in the management of breast cancer in elderly patients. Nevertheless, further large comparative studies are needed in order to validate such a minimally invasive procedure in current practice.
