OBJECTIVE: Patients with non-resectable liver metastases of colorectal cancer have poor prognosis and are mainly treated by palliative chemotherapy. Laser interstitial thermo-therapy is an innovative minimal invasive procedure for local tumour destruction within solid organs. The aim of the study was to investigate quality of life and outcome of ultrasound-guided laser interstitial thermo-therapy (US-LITT) in patients with liver metastases of colorectal cancer. METHODS: In this prospective non-randomized study, 45 patients with liver metastases of colorectal cancer were palliatively treated by US-LITT. Patient survival was analysed by the Kaplan-Meier method and the quality of life by questionnaire C30 of the European Organisation for Research and Treatment of Cancer before, and 1 week, 1 month, and 6 months after initiation of US-LITT. RESULTS: Median survival after initiation of US-LITT was 8.5 +/- 0.7 months with a range of 1.5-18 months. Body weight was constant 1 month after US-LITT. In the multivariate analyses, quality-of-life symptoms and functioning scales did not deteriorate in patients alive at 6 months after initiation of US-LITT. Univariate analyses outlined a significant increase of the pain subscale before and at 1 week after US-LITT. CONCLUSIONS: This study first describes the quality of life in patients with liver metastases of colorectal cancer treated by US-LITT. Potential benefits of the minimal invasive procedure could be prolonged survival time by preserved quality of life, but this first impression needs to be verified in a comparative study.
