Background and aim of the work: Interstitial Laser Photocoagulation (ILP) is a recently suggested method to ablate solid tumors by an interstitial approach. In this pilot clinical study we present our experience in treating neoplastic lesions of the liver. Methods: 44 lesions were treated in 23 patients, 7 suffering from HCC, 16 from hepatic metastases. The diameter of the lesions ranged from 10 to 65 mm. ILP was performed by a Nd-YAG Laser with optical fibres 0.8 mm in diameter via 18G needles positioned with US and/or CT guidance. With power ranging from 5 to 10W, the energy required in each treatment was 800-1.000 Joule. The extent of the tumour necrosis was evaluated with non-contrast and contrast-enhanced CT at 48 hours, 2 weeks and every 2 months. Results: Complete necrosis of neoplastic tissue was related to decrease in volume of the lesion and lacking the enhancement at CT. Among the 35 lesions with a follow-up of at least 2 months, 26 (74.3%) have shown at contrast-enhanced CT complete necrosis, 9 (25.7%) incomplete necrosis. There were no major complications. Conclusion: ILP is effective for tissue destruction of liver tumors. The therapy is reproducible, easily performed and minimally invasive.
