Salivary gland cancers rare, but sometimes deadly

Source: articles.baltimoresun.com Author: Andrea K. Walker Professional baseball great Tony Gwynn Sr., also known as Mr. Padre, died last month of salivary gland cancer, which he believed was caused by years of using smokeless chewing tobacco. The cancer is a rare form that begins in any of the salivary glands in the mouth, neck or throat. Two adults in 100,000 are diagnosed with salivary gland cancer each year. The chances of survival drop if the cancer has spread to other parts of the body. Dr. Patrick K. Ha, with Johns Hopkins Head and Neck Surgery at Greater Baltimore Medical Center, says new types of treatments and therapies are in the works to treat the disease. What is salivary gland cancer and how common is it? Salivary gland cancers are a diverse group of rare malignancies that can involve any of the major salivary glands (the parotid, submandibular and sublingual) or minor salivary glands, which are found within the lip, palate, tongue base, nasal cavity or sinuses. There are numerous different cancers that may arise from the salivary glands, and these may behave differently based on their cell of origin. What causes it, and who is more likely to get it? Little is known about the causes of salivary gland cancers. Unlike the more common head and neck cancers, which have a clear association with smoking, drinking or even the human papillomavirus (HPV), salivary gland cancers do not have such strong associations. There may be a link between significant radiation exposure (i.e., treatment [...]

An effective and well-tolerated strategy in recurrent and/or metastatic head and neck cancer: successive lines of active chemotherapeutic agents

Source: 7thspace.com Author: staff The combination platinum, 5-fluorouracil (5-FU) and cetuximab is the standard first-line regimen of recurrent and/or metastatic head and neck squamous cell carcinoma (HNSCC). Due to the toxicity of this treatment, alternative therapies are often offered to patients. The aim of this study was to evaluate the overall survival obtained with a first line chemotherapy adapted to patients functional status and the administration of all active drugs within successive lines of chemotherapy. Methods: This series included a total of 194 patients with recurrent and/or metastatic HNSCC treated from 2006 to 2011 in a single institution where the administration of successive lines of chemotherapies has been the standard clinical approach. Treatment was administered according to clinical practice guidelines. Results: Most patients received at least two treatment lines. Only 11 patients (6%) were treated with a combination of cisplatin, 5-FU and cetuximab in front line, but most patients received at least one platinum-based regimen (n = 154 patients, 78%); 162 (82%) received taxanes, 36 (18%) received 5-FU, 27 (14%) received capecitabine, 67 (34%) received methotrexate and 134 (68%) received cetuximab. The median overall survival was 9.8 months (95% CI: 8.1-11.4 months) and reached 13.1 months among the subgroup of 131 patients eligible for inclusion in a clinical trial. Conclusion: The survival outcomes of patients treated in the first-line setting with chemotherapy regimens adapted to their functional status, followed by several subsequent regimens were comparable with published outcomes of patients treated by platinum, 5-FU and cetuximab.

ACS awards $1.7M to study racial disparities in HNC patients

Source: http://www.drbicuspid.com/ Author: DrBicuspid Staff The American Cancer Society (ACS) has awarded a $1.7 million grant to Philadelphia researchers to investigate factors that may contribute to the racial disparities seen among those diagnosed and treated for head and neck cancers (HNC) -- specifically head and neck squamous cell carcinoma (HNSCC). While head and neck cancers account for only 3% of all cancers in the U.S., a disproportionately high number of African Americans are affected. Recent research has shown that other biological factors, and tobacco and alcohol use, may have a role in the development of these cancers. Other studies suggest that low socioeconomic status and poor healthcare access are the main contributors to this disparity. "Studies on genes involved in tobacco and drug metabolism and efflux suggest an association of genetic variants with head and neck cancer risk and survival in populations of European and Asian ancestries," stated Camille Ragin, PhD, an associate professor at the Fox Chase Cancer Center and the study's principal investigator, in a press release. "Genetic variants associated with the survival disparity of head and neck cancer in African-derived populations, however, is not yet clear." An accumulation of cancer-causing compounds occurs when products from tobacco smoke enter the body's cells, in some cases enabled by alcohol, and are broken down by proteins. Variations in the genetic code that generate these proteins can lead to differences in their function and could affect the way disease may develop or respond to drug therapy. In many cases, the genetic [...]

Selective apoptotic cell death effects of oral cancer cells treated with destruxin B

Source: 7thspace.com Author: press release Recent studies have revealed that destruxins (Dtx) have potent cytotoxic activities on individual cancer cells, however, data on oral cancer cells especial human are absent. Methods: Destruxin B (DB) was isolated and used to evaluate the selective cytotoxicity with human oral cancer cell lines, GNM (Neck metastasis of gingival carcinoma) and TSCCa (Tongue squamous cell carcinoma) cells, and normal gingival fibroblasts (GF) were also included as controls. Cells were tested with different concentrations of DB for 24, 48, and 72 h by MTT assay. Moreover, the mechanism of cytotoxicity was investigated using caspase-3 Immunofluorescence, annexin V/PI staining, and the expression of caspase-3, Bax, and Bcl-2 by western blotting after treated with different concentrations of DB for 72 h as parameters for apoptosis analyses. Results: The results show that DB exhibited significant (p <0.01) and selective time- and dose-dependent inhibitory effects on GNM and TSCCa cells viability but not on GF cells. The data suggested that DB is capable to induce tumor specific growth inhibition in oral GNM and TSCCa cancer cells via Bax/Bcl-2-mediated intrinsic mitochondrial apoptotic pathway in time- and dose-dependent manners. Conclusions: This is the first report on the anti-proliferation effect of DB in oral cancer cells. The results reported here may offer further evidences to the development of DB as a potential complementary chemotherapeutic target for oral cancer complications.

Researchers find way to diagnose aggressiveness of oral cancer

Source: www.news-medical.net Author: staff Studying mouth cancer in mice, researchers have found a way to predict the aggressiveness of similar tumors in people, an early step toward a diagnostic test that could guide treatment, according to researchers at Washington University School of Medicine in St. Louis. "All patients with advanced head and neck cancer get similar treatments," said Ravindra Uppaluri, MD, PhD, associate professor of otolaryngology. "We have patients who do well on standard combinations of surgery, radiation and chemotherapy, and patients who don't do so well. We're interested in finding out why." Reporting in Clinical Cancer ResearchK/em>, the investigators found a consistent pattern of gene expression associated with tumor spreading in mice. Analyzing genetic data from human oral cancer samples, they also found this gene signature in people with aggressive metastatic tumors. "We didn't automatically assume this mouse model would be relevant to human oral cancer," said Uppaluri, who performs head and neck surgeries at Barnes-Jewish Hospital. "But it turns out to be highly reflective of the disease in people." Rather than use genetic methods to induce tumors in the mice, the research team repeatedly applied a known carcinogen, in much the same way humans develop cancer of the mouth. "Patients often have a history of tobacco and alcohol use, which drive the development of these tumors," Uppaluri said. "We felt that exposing the mice to a carcinogen would be more likely to produce similar kinds of tumors." The researchers, including first author Michael D. Onken, PhD, research assistant [...]

Gwynn’s death sparks dip debate

Source: www.trentonian.com Author: Nick Peruffo The death of San Diego Padres icon Tony Gwynn due to oral cancer Monday resonated across the baseball world — including the Trenton Thunder clubhouse. In addition to being a person tragedy for the Gwynn family, the news also put a renewed focus on the use of chewing tobacco in baseball. Officially, tobacco in any form has been banned in the minor leagues since 1993. If caught with chewing tobacco on the field, players face a $300 fine, while managers are docked $1,000. Away from the field, however, it is clear that some players continue to dip. “There are so many guys that do it,” said catcher Tyson Blaser, who does not use chewing tobacco. “It’s very common in the major leagues, and even though obviously in the minor leagues you are not supposed to do it, some people don’t adhere to that. To see an icon like (Gwynn) lose his battle with cancer because of a habit a lot of people do, I assume it’d be eye opening to some people.” Gwynn, who was just 54, blamed his cancer on dipping tobacco. Despite that, manager Tony Franklin conceded that while the coaching staff does its best to dissuade players from using, what they do on their own time is ultimately their own decision. “We encourage them not to do it, but they are adults with choices to make,” Franklin said. “The choices they make could be very beneficial and save their lives, so we [...]

Long term cerebral and vascular complications after irradiation of the neck in head and neck cancer patients: a prospective cohort study: study rationale and protocol

Source: 7thspace.com Author: staff Successful treatment options for cancer result in more young long-term survivors prone for long-term complications. Carotid artery vasculopathy is a potential long-term complication after radiotherapy of the neck, resulting in cerebrovascular events and probably deficits in cognitive and motor functioning. Better insight into the underlying pathofysiology of radiotherapy induced carotid artery vasculopathy is needed for prognostic purposes and to develop preventive strategies. Methods: The current study is a prospective cohort study on the long-term cerebral and vascular complications after radiotherapy of the neck, in 103 patients treated for head and neck cancer, included in our study database between 2002 and 2008. Baseline protocol (before radiotherapy) included screening for cerebrovascular risk factors and intima media thickness measurement of carotid arteries by ultrasonography. Follow-up assessment more than 5 years after radiotherapy included screening of cerebrovascular risk factors, cerebrovascular events, neurological examination with gait and balance tests, extensive neuropsychological examination, self-report questionnaires, ultrasonography of the carotid arteries with measurement of intima media thickness and elastography, magnetic resonance imaging of the brain and magnetic resonance angiography of the carotid arteries.DiscussionThe current study adds to the understanding of the causes and consequences of long-term cerebral and vascular changes after radiotherapy of the neck. These data will be helpful to develop a protocol for diagnostic and preventive strategies for long-term neurological complications in future head and neck cancer patients with anticipated radiotherapy treatment.

FDA approve Lymphoseek to evaluate head and neck cancer

Source: www.medicalnewstoday.com Author: Catharine Paddock PhD The US Food and Drug Administration have given the OK for doctors to use Lymphoseek - a radioactive diagnostic imaging agent - to evaluate the spread of squamous cell carcinoma in the body's head and neck region. Lymphoseek (technetium 99m tilmanocept) Injection was approved by the Food and Drug Administration (FDA) in 2013 to help doctors identify lymph nodes closest to primary tumors in patients with breast cancer and melanoma. The receptor-targeted lymphatic mapping agent is marketed by Navidea, a biopharma company based in Dublin, OH. Identification of lymph nodes in cancer is important because they filter fluid that drains from tissue. If this tissue is cancerous then the fluid will contain cancer cells, and testing lymph nodes - via biopsy - for presence of cancer cells helps determine if the cancer has spread. The approval of Lymphoseek for use in head and neck cancer patients means doctors will be able to use the agent to guide testing of sentinel nodes - lymph nodes closest to a primary tumor - allowing for the "option of more limited lymph node surgery in patients with sentinel nodes negative for cancer," say the FDA. In a clinical trial, researchers found that "Lymphoseek-guided sentinel lymph node biopsy accurately determined if the cancer had spread through the lymphatic system." Dr. Libero Marzella, director of the Division of Medical Imaging Products in the federal agency's Center for Drug Evaluation and Research, says: "For some patients with head and [...]

Researchers bring oral cancer-fighting patch to patients

Source: medicalxpress.com Author: staff The Ohio State University and the University of Michigan have signed an exclusive worldwide agreement with Ohio-based Venture Therapeutics, Inc, to form a new company to develop and commercialize a pharmaceutical technology targeted for the treatment of precancerous oral lesions. These lesions are currently managed by invasive surgery and approximately a third of these lesions will reoccur after surgery. Previously published data shows that about 30 percent of the higher grade precancerous oral lesions progress to oral cancer, specifically oral squamous cell carcinoma. This type of cancer is particularly devastating to patients because treatment entails removal of facial and mouth structures essential for esthetics and function. The National Cancer Institute estimates that 42,440 Americans will be diagnosed with oral cancer and over 8,390 oral cancer related deaths will occur in 2014. The pharmaceutical technology developed by researchers at The Ohio State University (OSU) College of Dentistry with secondary appointments at the OSU Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James) and the University of Michigan addresses a significant unmet need related to the prevention of oral cancer. Precancerous oral lesions can be seen and touched by patients, so this easy access to the lesion allows the use of local delivery formulations in an oral patch to directly treat the disease without causing adverse side effects. "This type of collaboration, involving multiple university partners with strong industry support, is increasingly essential to expedite the discovery, development and [...]

Grateful Dead guitarist plays concerts with tribute band to benefit the Oral Cancer Foundation

Source: truebluetribune.com Author: staff Mark Karan, former lead guitarist for the post Grateful Dead band, The Other Ones, and Joe Pulitano, drummer for the Grateful Dead tribute band, Deadbeat, who are both stage IV oral cancer survivors, recently teamed up to play three benefit concerts in the North East to raise money for the Oral Cancer Foundation and the Dana Farber Cancer Institute. Following Deadbeat’s benefit performances this spring, with Mark playing guest guitar, the two men donated $7,500 of the concert proceeds to the Oral Cancer Foundation to support the organization’s research, advocacy, and educational efforts. What’s interesting is how these two talented musicians, who did not know each other before their individual encounters with this deadly disease, came together. Like many who find themselves dealing with oral cancer, Joe had complained for 14 months to his doctor about voice change, shortness of breath when speaking, and a sore throat. He was eventually diagnosed with stage IV head and neck cancer. Years before Mark’s diagnosis with oral cancer, and after Jerry Garcia’s death, he was chosen to share his lead guitar slot with Steve Kimock in the Other Ones. Just two years ago, while laying in a hospital bed, Mark asked his wife to hand him his guitar and a piece of paper. Twenty minutes later, “Walk Through Fire” was written, a song about his personal resolve, humility, acceptance, courage and lessons learned in his brush with the life-threatening disease. “It was one of those songs you hope for, [...]
