Abstract [eng] |
Background/Objective. This retrospective study aimed to clarify one of the minimally invasive therapies – Radiofrequency ablation (RFA) – performance, extremeness and 5-year survival in patients with small renal tumors. Patients and methods. 118 patients (77 men (65%), and 41 women (35%) with mean age of 68.72 (± 10.12 ) years) were treated with RFA method in Vilnius University Institute of Oncology Urology Section, and since 2003 September 17 till 2012 December 6 were performed 144 renal tumor RFAs. All renal tumors RFAs were performed percutaneously in the projection of the skin, under local or general anesthesia. Procedures were performed by one or several small (up to 1 cm) incisions, and in the US control electrodes were introduced. Since May 2011, 30 RFAs were performed with three electrodes and US control with CT navigation, just a day before the operation additionally titanium markers were put in around the kidney tumor. Results. Since 2003 till 2007 years our patient’s follow-up method was US examination. However, in case of suspicion of tumor progression, percutaneous renal biopsy and CT were performed. From 2007 year patients were follow-up with CT. The ablation zone, contrast agent accumulation and the ablation of the edge were evaluated. Average tumor size was 2.8 (± 0.9) cm. By histology, mainly there were malignant tumors, much less benign, a minority remained histologically unconfirmed. In our study we found out that the most radical renal tumor RFAs were done in the control of US with CT navigation, when additionally around the renal tumor titanium markers were added. Also we clarified, that procedure is more radical when performed using three electrodes. The most common postoperative complication was paranephric hematoma. Conclusions. After RFA, 2-year survival rate is 90 %, 5 years – 58%. Death risk factors: tumor size, higher ASA class, non-radical surgery, metastases or other oncologic process. |
