Local Efficacy and Survival after Microwave Ablation of Lung Tumors: A Retrospective Study in 183 Patients

The safety and efficacy of microwave ablation for the treatment of CRC pulmonary metastases

“…We followed up all 32 patients in our study. The median DFI was 15 months from the time of the primary operation, and the median survival time was 31 months, similar to the reported studies [36]. Belforie et al [19] reported cancer-specific mortalities of 69%, 54% and 49% at 1, 2 and 3 years in 56 patients treated with MWA.…”

“…In the present study, the 1-, 2-and 3-year survival rates were 79.5%, 63.1% and 44.4%, respectively. Reported independent predictors of OS include location of primary disease for lung metastasis [37], tumour stage [36], number of metastases [37], tumour size [20,36,37] and extrapulmonary metastasis [38]. In the present study, multivariate analysis showed that tumour size was an independent prognostic factor for survival.…”

“…Previous studies have shown that MWA therapy can improve the survival rate of patients with pulmonary metastases [30,35]. Aimin et al [36] have reported a 38.3-month median OS in the solitary metastasis group after lung MWA. We followed up all 32 patients in our study.…”

Microwave Ablation in Primary Lung Malignancies

“…The reported primary technical success rate for MWA ranges from 80 to 100%. 24,39 The lower margin of this technical success rate is compensated by the fact that the ablation can be repeated multiple times until adequate margins are achieved. The reported median time to recurrence was as high as 39.7 months in one study, with strong association with original tumor diameter.…”

Comparison between microwave ablation and lobectomy for stage I non-small cell lung cancer: a propensity score analysis

“…The results in the study by Takao Hiraki et al [29] showed that the local control rates of stage I NSCLC after RFA were 72% at 1 year, 63% at 2 years and 63% at 3 years. Amini Zheng et al [30] reported that after MWA, the local progression rates in the tumour with a maximum diameter <3, 3.1-5 and >5 cm were 7.4, 27.4 and 42.3%, respectively. Our data showed the better local control of MWA, which might be ascribed to the much bigger MWA lesion.…”
