title: Interstitial photoablative laser therapy guided by magnetic resonance imaging for the treatment of deep tumors.
abstract: The failure rate of cancer treatment remains unacceptably high, still being a leading cause of mortality in adults and children despite major advances over the past 50 years in the fields of surgery, radiation therapy, and, more recently, chemo and immunotherapy. In the United States, the 5-year survival rate for all cancers in the population has increased by only approximately 10% since 1960. Surgical access to some deep tumors of the head and neck and other areas often require extensive dissections with residual functional and cosmetic deformities. Repeated treatment is not possible after maximum dose radiotherapy and chemotherapy is still limited by its systemic toxicity. An attractive solution to these problems would be the development of a new adjunctive method combining the best features of interstitial laser phototherapy for selective tumor destruction via minimally invasive techniques for access and 3D-magnetic resonance imaging (MRI) as a monitoring system for laser-tissue interactions. Our experience with this new technique is reviewed.
