OBJECTIVE: This retrospective study aimed to compare feasibility, complication rate and local tumor control after radiofrequency ablation (RFA) of pulmonary tumors under conscious analgo-sedation (AS) versus general anaesthesia (GA). MATERIALS AND METHODS: Within 36 months 21 patients had RFA (36 tumors, 26 treatment sessions). One patient suffered from NSCLC, 20 had metastases (breast (8/20), colorectal (6/20), renal cell (2/20), pharyngeal carcinoma (1/20), malignant melanoma (3/20)). Patients were no surgical candidates due to underlying comorbidities. Eleven of 26 treatments were performed under GA, while in 15 of 26 treatments AS was used. Follow-up was scheduled 24 h, 6 weeks, 3 months, 6 months and then every 6 months after treatment. RESULTS: RFA was feasible in all treatments under GA, while under AS targeting of the lesion was not possible in 2/15. Six adverse events occurred in the GA group (three major, three minor), while seven complications happened in the AS group (three major, four minor) (p=0.57). During follow-up of 3-36 months local recurrence was detected in 3 of 21 tumors in the GA group and in 2 of 15 tumors in the AS group (p=0.79). DISCUSSION: Hospitalization, complication rates and types, and the rate of local tumor control did not differ substantially among both groups. Furthermore, there was no significant difference in technical success and feasibility. CONCLUSION: RFA of pulmonary tumors under GA or AS did not result in different tumor control and complication rates, respectively. Therefore, AS should be used except in anxious or agitated patients.
