Proton beam therapy shows encouraging long-term outcome for patients with locally advanced sinonasal cancers

Proton beam radiation therapy shows encouraging results for patients with locally advanced sinonasal malignancies, according to a study presented at the Multidisciplinary Head and Neck Cancer Symposium, sponsored by AHNS, ASCO, ASTRO and SNM.

Sinonasal cancers are very rare but aggressive types of cancer. Patients usually present with advanced stage with tumors involving normal structures in the skull base such as eyes, optic nerves, brain. Between 1991 and 2003, 99 patients with newly diagnosed sinonasal cancers were treated with proton beam therapy at Massachusetts General Hospital in Boston.

Sixty-seven percent of the patients had some type of surgery prior to their radiation. The median total dose to the primary tumor was 70 Gray. After a median follow-up of 8.5 years, the local control rates at five and eight years were 87 percent and 83 percent, respectively, and there was no statistically significant difference in local control per histological subtype, T stage, and surgery vs. biopsy.

"Due to the anatomical location of sinonasal cancers, conventional radiation therapy results in very poor local control and is associated with significant treatment-related toxicity," Annie Chan, M.D., a radiation oncologist and the principal investigator of the study at Massachusetts General Hospital, Harvard Medical School, said. "Proton beam radiation therapy, with its superior dose distribution, allows the delivery of higher doses of radiation to the tumor while sparing more or the healthy surrounding tissues. This study showed very encouraging results for these patients and now prospective multi-institutional studies are being planned to further study the use of proton therapy in the treatment of this rare but aggressive malignancy."

The abstract, "Long-term Outcome of Proton Beam Therapy for Advanced Sinonasal Malignacies," will be presented in the plenary session on Thursday, February 25, 2010. To speak with one of the study authors, contact Beth Bukata or Nicole Napoli on February 25-26, 2010, in the press room at the Sheraton Wild Horse Pass Resort and Spa at 520-796-8228.

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
