Laparoscopic microwave thermosphere ablation of malignant liver tumors: An analysis of 53 cases

Abstract

The results of this series confirm the safety and feasibility of MTA technology. The 99.3% rate of complete tumor ablation and low rate of local recurrence at short-term follow up are promising.

External radiation or ablation for solitary hepatocellular carcinoma: A survival analysis of the SEER database

“…This study demonstrates an increasing risk of death as tumor size increases. These results support previous work correlating size of HCC lesions to outcomes following ablation . The hazard ratios with increasing size reported by the current study demonstrate that 3 cm is an important metric to guide therapeutic decisions.…”

Laparoscopic access to the liver and application of laparoscopic microwave ablation in 2 dogs with liver neoplasia

“…Laparoscopic microwave ablation was reported to have low rates of incomplete ablation and local recurrence, 3% and 6%, respectively, in one human study . In another human study by Zaidi et al, 47 patients received LMWA treatment for hepatic neoplasias, and only 1 patient was found to have incomplete ablation via postoperative CT. During this series, complete tumor necrosis was achieved in 99.3% of the cases, and, to the best of the authors' knowledge, the local recurrence rate was the lowest documented in the human literature, 0.7% . Their success was attributed to the use of LMWA in combination with intraoperative ultrasound that improved prediction of the ablation zones .…”

“…Laparoscopic microwave ablation has been described in the human literature to treat nonresectable hepatic masses . The use of this technique has been reported for different types of liver neoplasias or primary or metastatic diseases . Microwave ablation has been described in veterinary medicine for the treatment of liver neoplasia, but never under laparoscopic guidance .…”

A comparison between 915 MHz and 2450 MHz microwave ablation systems for the treatment of small diameter lung metastases

“…The publications currently available concerning the HF system are scarce and consist of an ex vivo temperature monitoring study and one percutaneous and two laparoscopic liver ablation patient series (11,(18)(19)(20). To the best of our knowledge, no reports regarding lung ablations with the new HF system are available.…”
