Response Rate to Chemotherapy for NSCLC not Affected by Ethyol

5/2/2007 web-based article staff CancerConsultants.com Researchers from the MD Anderson Cancer Center have reported that response rates for locally advanced non-small-cell lung cancer (NSCLC) to chemotherapy are not affected by Ethyol® (amifostine) cytoprotection. The details of this study appeared in an early on-line publication in the International Journal of RadiationOncology* Biology* Physics on February 6, 2007. Ethyol® is a radiation protector and the only drug that has been approved by the FDA for this use in patients receiving radiation therapy for cancers of the head and neck. Clinical trials have demonstrated that Ethyol can reduce both acute and late radiation-induced side effects. In the pivotal trial involving patients with head and neck cancer, Ethyol reduced the incidence of xerostomia but had no effect on the incidence or severity of oral mucositis. Ethyol has also been shown to reduce the incidence of grade 2-3 bladder and GI toxicities in patients receiving pelvic radiation therapy. However, the results with Ethyol are conflicting in patients with NSCLC who are receiving radiochemotherapy. A previous study from the MD Anderson Cancer Center reported that Ethyol reduces the severity and incidence of acute esophageal, pulmonary, and hematologic toxicity resulting from concurrent cisplatin-based chemotherapy and radiation therapy in patients with NSCLC. The authors of this study performed a meta-analysis of 7 randomized trials involving Ethyol in patients with NSCLC treated with radiotherapy with or without chemotherapy. There were 601 patients in these studies and data on response were available on 552 patients. They reported that there were [...]

Exercise science principles strengthen swallowing rehabilitation

5/1/2007 web-based article staff Huliq (www.huliq.com) Just thinking about swallowing rehabilitation makes it harder to do. Head and neck cancer, a stroke, brain tumor, brain injury or even a tracheostomy tube and mechanical ventilation needed to sustain life can make it impossible. Dysphagia, or swallowing problems, can also result from aging and accompanying loss of muscle strength. "We swallow a thousand times or more per day, just our own saliva, without even thinking about it," says Dr. Lori Burkhead, speech-language pathologist and clinical research scientist at the Medical College of Georgia Department of Otolaryngology – Head and Neck Surgery. "We swallow in our sleep. Babies do it in utero. It is something we do without giving it much thought, but it's actually a very complex act that involves an intricate coordination between the brain, muscles and respiratory system." An estimated 18 million Americans have difficulty with this routine function that, at worst, can lead to aspiration pneumonia, malnutrition, dehydration and death. Evidence suggests that the same exercise science principles that strengthen bodies can help restore this fundamental function using mouth and throat muscles. Because swallowing muscles are not easy to access, applying the usual principles of exercise is more difficult. "Physical therapists can put a weight in someone's hand and exercise them or they can give patients external assistance and get them to complete a movement," says Dr. Burkhead. "I can't put weights on throat muscles for strengthening and I can't get at those muscles to help patients finish the [...]

New Approaches To The Diagnosis Of Oral Cancer

5/1/2007 web-based article staff ScienceDaily.com Oral cancer is diagnosed in more than 30,000 individuals in the US annually, claiming 10,000 lives each year. Early detection remains the best way to ensure patient survival and quality of life. Today, during the 85th General Session of the International Association for Dental Research, scientists from the University of California-Irvine present two novel, non-invasive, ultra-fast imaging approaches to oral cancer detection, diagnostic screening, and mapping. More than 2/3 of all oral cancer cases documented by the National Cancer Institute are diagnosed at an advanced stage. The five-year survival rate is 75% for those with localized disease at diagnosis, but only 16% for those with cancer metastasis. Earlier detection of oral lesions would greatly improve the prognosis of these patients. Accurate delineation of lesion margins would ensure effective removal of all the tissue that presents a threat to the patient's long-term health. Two basic facts indicate that early detection of oral malignancy should be possible to a far greater extent than is currently seen: (1) Accounting for 96% of all oral cancers, squamous cell carcinoma is often preceded by lesions on the oral mucosa. Malignant transformation, which is quite unpredictable, occurs in 1-90% of lesions over five years. Thus, oral cancer is often preceded by lesions which are visible to the naked eye prior to transformation. A non-invasive diagnostic modality would permit regular monitoring of these lesions, detection of lesion transformation, and the identification of treatment needs at a very early, relatively harmless stage. (2) [...]
