BACKGROUND: Many @entity5 may cause liver @entity3 , which are generally treated with surgical resection and/or chemotherapy. After resection of liver @entity3 in @entity1 with @entity14 , 5-year survival rates are achieved in 25-38%, and two-thirds of @entity1 will experience recurrent @entity3 . We examined percutaneous, minimally invasive, @entity910 ( @entity910 ) as an alternative outpatient procedure. @entity5 control rate and survival data were analyzed prospectively. METHODS: Between June 1993 and August 2000, 7148 laser applications were performed in 1981 lesions in 705 consecutive @entity1 and 1653 treatment sessions. The complications of the procedure were evaluated by clinical examination and magnetic resonance imaging (MRI) and computed tomography. @entity5 control was evaluated by plain and contrast-enhanced follow-up MRI using T1- and T2-weighted spin-echo and gradient-echo sequences every 3 months after treatment. Cumulative survival times were calculated using the Kaplan-Meier method. RESULTS: The overall rate of complications and side effects was 7.5%. The rate of clinically relevant complications was 1.3%. @entity5 control rate after 3 months was 99.3%; 6 months after laser treatment, plain and contrast-enhanced MRI documented a @entity5 control rate of 97.9%. In @entity1 treated with MR-guided @entity910 for unresectable colorectal liver @entity3 , the mean survival was 41.8 months (95% confidence interval = 37.3-46.4 months). The 1-year survival rate was 93%, the 2-year survival rate was 74%, the 3-year survival rate was 50%, and the 5-year survival was 30%. In @entity1 treated with @entity910 for liver @entity3 from @entity0 , the mean survival was 4.3 years (95% confidence interval = 3.6-5.0 years). CONCLUSION: In @entity1 with liver @entity3 , @entity5 destruction using minimally invasive, percutaneous @entity910 under local anesthesia results in improved clinical outcomes and survival rates and can be a potential alternative to surgical resection.
