Targeted radiation, drug therapy combo less toxic for recurrent head, neck cancers

Source: medicalxpress.com Author: University of Pittsburgh Schools of the Health Sciences Patients with a recurrence of head and neck cancer who have previously received radiation treatment can be treated more quickly, safely and with fewer side effects with high doses of targeted radiation known as Stereotactic Body Radiation Therapy (SBRT) in combination with a drug that also carefully targets cancerous tumors. These findings from a UPMC CancerCenter study were presented today at the American Society of Radiation Oncology (ASTRO) annual meeting in San Francisco. SBRT uses concentrated radiation beams in high doses to destroy tumors in difficult or hard-to-reach areas. The treatment is noninvasive, which minimizes damage to surrounding healthy tissue and organs. Clinicians at UPMC CancerCenter, partner with the University of Pittsburgh Cancer Institute (UPCI), used SBRT in combination with the drug cetuximab for patients who had a recurrence of squamous cell carcinoma of the head and neck after going through radiation. "The prognosis for patients who have a recurrence of head and neck cancer that cannot be surgically removed is already poor. Traditional treatments can be associated with significant side effects so severe that patients give up on the therapy altogether," said Dwight E. Heron, M.D., vice chairman of radiation oncology at UPCI and director of Radiation Oncology Services at UPMC CancerCenter. "By taking these patients through an abbreviated course of targeted drug and SBRT, we minimize the side effects of treatment." Doctors treated 48 patients with the combination therapy between July 2007 and March 2013. All of [...]

New radiotherapy technique proven safe, less toxic for cancer patients, University Of Pittsburgh Cancer Institute study finds

Source: Medicalnewstoday.com Author: Staff A new technique known as stereotactic body radiotherapy (SBRT) is safe for patients with recurrent head and neck cancers and may improve their quality of life, according to researchers from the University of Pittsburgh Cancer Institute (UPCI). Results of the phase I study were reported today in the International Journal of Radiation Oncology, Biology, Physics. Each year approximately 500,000 cases of squamous cell carcinoma of the head and neck are diagnosed worldwide. While treatment has improved with advances in surgery, radiation and chemotherapy, more than half of patients will die from recurrent disease. Treatment options for patients with recurrent disease are limited, and for many, surgery may not be an option, according to principal investigator Dwight E. Heron, M.D., director, Radiation Oncology Services, UPMC Cancer Centers. "Chemotherapy alone can provide this patient population some palliation and pain relief, but it doesn't prolong survival," said Dr. Heron. "A few patients may be able to receive additional radiation treatments, but head and neck cancers, by their very nature, develop in very delicate areas of the body, which provide significant retreatment challenges." SBRT may offer these patients an alternative, noted Dr. Heron. "At the completion of our study, we found this treatment was tolerated very well. No maximum tolerated dose was reached, and no toxicities occurred that caused us to limit the dosing." SBRT is a relatively new technique using CyberKnife® technology, which delivers high doses of radiation with more precision than conventional techniques. The vast majority of patients complete [...]
