Abstract
Interstitial laser coagulation (ILC) is a new method of producing localized tissue destruction, that may be used to eliminate soli tumors, such as liver metastases, pancreatic carcinomas, brain glioma and benign prostate hyperplasia. In ILC, Nd:YAG laser light is guided through flexible quartz fibers implanted directly into the tumor. Several experimental studies have shown the effectiveness of this therapy. Clinical application is feasible, however success in malignant tumors is limited by: (1) the restricted lesion size produced by a single optical fiber and (2) the lack of reliable on-line monitoring of the laser-induced effects. Research is therefore directed towards the development of multiple fiber application, guided by real time feedback of the laser-tissue interaction.
