Laser-induzierte Thermotherapie (LITT) von Lungenmetastasen: Beschreibung eines miniaturisierten Applikators, Optimierung und erste Patientenbehandlungen

Abstract: The miniaturized applicator system enables the introduction of a laser fiber into pulmonary metastases with only minor complications. Complete ablation seems to be achievable in suitable patients with the applied laser energy and a slow cooling fluid flow rate.

“…Most groups use RFA for thermal ablation of the lung, but LITT is preferred by some groups [ 3 , 7 , 8 ] ; and it has been suggested that lung-specific conduction of laser light improves therapeutic success and tumor control compared with RFA [ 9 ] . Although the properties of lung tumors are different from the properties of normal lung tissue, normal lung tissue often surrounds tumors and may limit RF current flow, which may limit sufficient ablative margins or make the ablation zone less predictable.…”

“…Groups that use LITT have reported that LITT produces a more predictable lesion shape than RFA because electrical conductivity does not affect heat deposition [ 3 ] . However, it remains unknown whether varying the laser application protocol can affect the size of the ablation zone in the lung.…”

“…Vorteile sind im Vergleich zur Chirurgie der geringere Aufwand, z. B. durch das Fehlen der Intubationsnarkose, und die geringere Invasivität [31,32].…”

“…Zudem ist nun eine beliebige Kombination der bildgebenden Modalitäten (MRT, CT, Ultraschall), mit den spezifischen Vor-und Nachteilen, bei der Detektion, Platzierung, Positionskontrolle, echtzeitnahen Therapiekontrolle sowie der Ablationskontrolle bei der LITT als auch bei der RFA möglich [28,29]. Aktuell stehen außerdem miniaturisierte Applikatorsysteme zur Verfügung, die bei geringeren Außenabmessungen und damit gesunkenem Komplikationsrisiko Laserleistungen bis zu 15 Watt erlauben [30]. Sie sind zurzeit in der klinischen Erprobung bei Lungen-und Lebertumoren.…”
