Summary

Microwave thermal ablation (MO) is recognized as an alternative to surgery for the local-regional treatment of primary and secondary hepatic and renal tumors and for secondary pulmonary tumors in patients at anesthetic and/or surgical risk.

Microwaves have a reputation for not producing reproducible ablation volumes with elliptical deformations and risks of over or under processing.

The Covidien manufacturer offers a microwave system that guarantees more spherical and reproducible ablations: Emprint TM ablation system with Thermosphere TM technology (thermal control, field control, wavelength control).

The investigators have 2 years of experience and therefore propose to carry out a first retrospective study, on a cohort of about fifty patients, whose objective will be to compare the volume of in vivo ablation one month after thermo-ablative treatment by microwave of a hepatic, renal or pulmonary tumour with the reference volume announced by the Covidien abacus manufacturer.

Microwave ablation, which is much less studied, is less used because of the low reproducibility of necrosis volumes.

The Covidien manufacturer offers a system that allows ablation volumes that are supposed to be reproducible, which attracted the Nîmes University Hospital during the call for tenders.

To the investigator's knowledge, there are no studies that have evaluated the actual volume of ablation by this system.
