“…The applicator alters the surrounding tissue temperature either by internal cooling (cryoablation) or by heating with energy such as radiofrequency (RF) electrical current, microwaves (MWs), laser light, or ultrasound waves. 4,[8][9][10] Non-thermal techniques such as irreversible electroporation are also under investigation. 11 The choice of energy depends on the institution, tumor type and location, and available equipment.…”

Interventional oncology procedures such as thermal ablation are becoming routine for many cancers. Hydrodissection-separating tissues with fluids-protects tissues near the treatment zone to improve ablation's safety and facilitate more aggressive treatments. However, currently used fluids such as normal saline and 5% dextrose in water (D5W) migrate in the peritoneum, reducing their protective efficacy. As a hydrodissection alternative, we investigated a thermoreversible poloxamer 407 (P407) solution. Such a material can be injected as a liquid which then forms a semi-solid gel at body temperature without syneresis. The desired gelation temperature of 32°C was achieved with 15.4 wt/wt % P407. Viscosity analysis revealed the lowest viscosity and ideal injection point was at 14°C. Solution viscosity increased during gelation, to a peak of 65 kPa*s at 40°C. The electrical impedance of P407 was significantly greater than isotonic saline, but lower than D5W, indicating its potential for electrical protection. The P407 gel was similar to other hydrodissection fluids at ultrasound and CT imaging. Ex vivo liver ablations showed that P407 protects neighboring tissues, but may require a thicker barrier for comparable protection to D5W. Overall, we found that the P407 solution is a feasible alternative to traditional hydrodissection fluids and warrants additional study.

“…The use of ablation is widely accepted for both painful disease metastatic to bone and osteoid osteomas (5,86,87). Soft-tissue ablation is most frequently performed Although it would be reasonable to perform a biopsy of the lesion with an approach perpendicular to the pleural surface (black arrow), thus minimizing the lung parenchyma traversed, or with a more tangential approach, it is important with microwave ablation to use an approach that allows for an adequate tract within the lung parenchyma (white arrow).…”

“…Due to its intrinsic analgesic effect and the visualization characteristics of the ice ball during ablation, the use of cryoablation for treating osteoid osteoma is obvious. Intra-and post-operative pain is not as pronounced compared to e. g. RFA, so that treatment can also be performed under sedation [16,31]. Interestingly, there have to date been no large-scale published studies demonstrating the long-term clinical success of cryoablation.…”

“…Correspondingly, most clinical ablation systems employ compressed argon and helium for cooling and thawing, respectively; in such uses, temperatures below -140°C are achieved [15] (• ▶ Table 1). During ablation, the "ice ball" at the tip of the probe can be visualized directly, an advantage over other ablation techniques, for example during treatment of lesions adjoining critical structures (nerves, blood vessels) [16]. Whereas the diameter of the ice ball is essentially a function of the energy transfer rate (and thus dependent upon the flow rate of gas through the probe), the length of the ice ball is dependent upon the length of the non-insulated probe.…”

The aim of this article is to review the significance of percutaneous thermal ablation in the treatment of bone tumors. We describe available ablation techniques as well as advantages and disadvantages in specific settings. In detail, radiofrequency ablation (RFA), microwave ablation (MWA), laser ablation, high intensity focused ultrasound (HIFU) and cryoablation are presented. In the second part of this review curative and palliative indications for the treatment of benign and malignant bone tumors are discussed. This includes especially RFA, laser or cryoablation for the treatment of osteoid osteoma, as well as the palliative treatment of painful bone metastases, for example, by means of MWA or MR-guided HIFU. Key Points: ??The various thermoablative techniques demonstrate specific advantages and disadvantages. ??Radiofrequency ablation is the evidence-based method of choice for treating osteoid osteoma. ??Laser ablation is primarily suited for the treatment of small lesions of the hands and feet. ??The intrinsically analgesic effect of cryoablation is advantageous when treating painful lesions. ??Palliative treatment of painful bone metastases can for example be performed using MWA or MR-guided HIFU, by itself or combined with cementoplasty.
