Abstract
Thermal ablation an established alternative treatment for patients
who cannot undergo surgery because of their compromised general
condition. Main indications are represented by early stage (I/IIN0) lung
cancer. In the case of pulmonary metastasis, most authors agree to offer
TA only if lesions are smaller than 5 cm (Alessandro et al., 2008).
Percutaneous thermal ablation broadens the range of treatment
options for patients who are not candidates for surgery. However, the local
control that can currently be achieved must be measured against that
achieved by stereotactic radiotherapy(Schneider et al., 2013).
Tumor ablation should always be indicated on the basis of
interdisciplinary consensus through a tumor board including
pulmonologists, oncologists, thoracic surgeons, radiotherapists, and
radiologists in line with the guidelines for lung cancer and all treatment
options should be weighed. (Schneider et al., 2013).
Microwave ablation is a safe procedure, with reduced costs and
short hospital stay, which guarantees a high success rate of complete
ablation. This gives patients who are not eligible for surgery the
opportunity of a curative treatment(Fernando et al., 2010).
Microwave ablation therapy is a safe therapeutic tool for treatment
of pulmonary metastases. The efficacy of treatment is determined mainly
by pre ablation tumor size and location in relation to the hilum. Successful
microwave ablation of pulmonary metastases is more likely for peripheral

lesions of 3 cm or smaller. The pre ablation tumor size (< 3 cm) is the
most significant independent predictor of ablation success (Thomas et al.,
2011).
Careful selection of cases in which the benefit of ablation therapy
will outweigh the potential complications is the key to ensuring optimal
patient outcomes(Thomas et al., 2011).
The main advantages of microwave technology, when compared
with existing thermoablative technologies, include consistently higher
intratumoral temperatures, larger tumor ablation volumes, faster ablation
times, less susceptibility to heat-sink effects which could lead to a better
local disease control and long-term survival. and an improved convection
profile. Microwave ablation has promising potential in the treatment of
pulmonary metastasis. The technology is still in its infancy, and future
developments and clinical implementation will help improve the care of
patients with cancer (Lubner et al., 2011).
