Abstract
Although major progress has been made in surgery, radiation, and chemotherapy for the treatment of malignancy during the last 30 years, there has been little improvement in the survival of patients with recurrent or advanced head and neck cancer.Laser-induced thermotherapy (LITT) is a non-surgical method for treating tumors in solid organs. The method is experimental and considered primarily in treating patients with recurrent tumors when surgery is not an option.A recent phase II study at our institution showed that palliative LITT for 106 patients with recurrent lesions presented the best results in oral cavity tumors, in which mean survival was 29.1 months, as compared to neck tumors (mean 14.4 +/- 6.9 months; range 7.5-20.7 months; with a 95% confidence interval).Because of the ease and accessibility for surgery and their loco-regional biological behavior, head and neck cancers serve as an ideal model to test combined laser energy delivered via interstitial fiberoptics and chemotherapeutic agents activated by photo-thermal energy as an alternative, less invasive treatment for cancer. A number of investigators have shown that anthracyclines and cisplatin are likely candidates for light or heat activation in cancer cells. Maximum tolerated dose followed by photochemical and thermal activation via laser fiberoptics can improve treatment by sensitizing tumor response. The higher intratumor drug levels compared to systemic drug administration along with laser activation should also reduce systemic toxicity. In this presentation we review the concept of combining anti-cancer drugs and laser therapy and review the clinical experience for this novel application.
Biography

Dr. Uttam K. Sinha graduated with distinction from the Calcutta University, India in 1985. He was invited by the House Ear Institute and University of Southern California where he started his research career in molecular biology of neuroscience and cancer. He then finished residency in Otolaryngology-Head and Neck Surgery at USC. He continued to peruse academic career and completed a clinical fellowship in Microvascular and Plastic and Reconstructive Surgery in Mount Sinai Hospital, New York. He then went to Leon, France to complete a clinical fellowship in laryngology. Subsequently, he joined the faculty of the Department of Otolaryngology-Head and Neck Surgery at USC. Because of his academic achievements, leadership, teaching and research, he became Chief and Residency Program Director for the department. His major areas of research are head and neck cancer, thyroid cancer, plastic and reconstructive surgery, trauma, and speech and swallowing. By using nanotechnology, Dr. Sinha and his team are able to detect cancer cell in the saliva and serum. He is also studying the mechanism of metastasis. Dysphagia (difficulty in swallowing) is a common symptom following head and neck cancer therapy. Dr. Sinha and his team introduced a novel treatment called neuromuscular electrical stimulation (NMES) for rehabilitation of swallowing using a new platform technology called BION. He received multiple federal and foundation grants. His dedication to patient care and research made him world authority in head and neck diseases. To further the research endeavors, Dr. Sinha has established collaboration with multiple national and international institutes from England, France, India, China and Mexico. Three years ago Dr. Sinha launched a Patient Survivorship Program (http://hncsupport.org). The Support Group is actively involved in patient education and promoting awareness about head and neck.
