Zusammenfassung
Ziel: Die laserinduzierte interstitielle Thermotherapie (LITT) ist ein Verfahren zur lokalen Tumorablation. Die vorliegende Arbeit berichtet über die Langzeitergebnisse dieser Therapie bei Patienten mit inoperablen kolorektalen Lebermetastasen. Material und Methoden: Wir behandelten insgesamt 85 Patienten mit 163 inoperablen kolorektalen Lebermetastasen mittels LITT unter kernspintomografischer Kontrolle. Ergebnisse: Die Gesamtletalität betrug 1,1 %. Die Patienten überlebten im Mittel 3,3 ± 0,3 (CI: 2,8; 3,8) Jahre nach Diagnosestellung der Metastasen (Kaplan-Meier-Methode). Das mittlere Überleben nach LITT betrug 2,6 ± 0,2 Jahre (CI 2,2; 3,0). Es fand sich ein substanzieller Lerneffekt hinsichtlich der Indikationsstellung sowie der technischen Durchführung. In der ersten Behandlungsperiode (50 Patienten; 1998 - 2001) lebten die Patienten im Mittel 2,2 ± 0,2 Jahre (CI: 1,8; 2,7). Danach (35 Patienten; 2001 - 2006) stieg das mittlere Überleben auf 2,9 ± 0,3 Jahre an (CI: 2,4; 3,4; Log-rank-Test: p = 0,0097). In dieser Gruppe betrug die 1-Jahres-Überlebensrate 93 % und die 3-Jahres-Überlebensrate 56 %. Schlussfolgerung: Die LITT ist ein vergleichsweise komplikationsarmes Verfahren zur Behandlung inoperabler kolorektaler Lebermetastasen. Die Überlebenszeiten sind länger als diejenigen, die für eine alleinige Behandlung mittels Chemotherapie in vergleichbaren Patientenkollektiven berichtet wurden.
Abstract
Purpose: Laser-induced interstitial thermotherapy (LITT) is a minimally invasive procedure for local tumor ablation. This report discusses the long-term results of this therapy in non-surgical patients with colorectal liver metastases. Materials and Methods: In total, we treated 163 colorectal liver metastases in 85 patients by MR-guided LITT. Results: The overall lethality was 1.1 %. The mean survival period of all treated patients was 3.3 ± 0.3 years (CI: 2.8; 3.8; Kaplan-Meier method) with a calculation start date of the diagnosis of the metastases. The mean survival period after LITT was 2.6 ± 0.2 years (CI 2.2; 3.0). There was a substantial learning curve with respect to the indication for LITT and the technical procedure of the intervention itself. In the first period (50 patients; 1998 - 2001), the mean survival period was 2.2 ± 0.2 years (CI: 1.8; 2.7). Thereafter (35 patients 2001 - 2006), the mean survival period increased to 2.9 ± 0.3 years (CI: 2.4; 3.4; log rank Test; p = 0.0097). In the latter group, the 1-year survival rate was 93 % and the 3-year survival rate was 56 %. Conclusion: MR-guided LITT is a treatment suitable for non-surgical patients suffering from colorectal liver metastases. The complication rate of the procedure is comparatively low. The survival periods after the procedure are longer than those reported for similar patient populations after chemotherapy alone.
