Dentists asked to help in curbing mouth cancer

Source: Author: The increasing cases of oral cancer have pushed the Cancer Research UK to ask dentists to look for cancer related symptoms in their patients. By checking the mouth properly, dentists can gauge whether or not a person is prone of developing mouth cancer. Mouth cancer can be lethal if timely treatment isn't provided to the patients. Smoking and heavy drinking could be one of the reasons behind causing mouth cancer. Chewing tobacco is yet again contributing to mouth cancer. While examining the patients, the dentists have been advised to look for cancer contributing factors. It is estimated that by 2030 there will be an increase in the number of mouth cancer patients. People under the age group of 50 years are growing becoming victim of mouth cancer. Oral sex is yet another factor that could lead to mouth cancer. People need to be made aware about the growing incidences of mouth cancer so that innocent lives could be saved. Avoiding heavy drinking, smoke and unhygienic oral sex can help in preventing mouth cancer. Besides, dentists can also help in saving lives by detecting mouth cancer earlier through regular checkups. It is hoped that the dentists will take serious note of the recommendations.

Oropharyngeal cancer patients with HPV have a more robust response to radiation therapy

Source: Eurekalert.org (SACRAMENTO, Calif.) — UC Davis cancer researchers have discovered significant differences in radiation-therapy response among patients with oropharyngeal cancer depending on whether they carry the human papillomavirus (HPV), a common sexually transmitted virus. The findings, published online today in The Laryngoscope Journal, could lead to more individualized radiation treatment regimens, which for many patients with HPV could be shorter and potentially less toxic. HPV-related cancers of the oropharynx (the region of the throat between the soft palate and the epiglottis, including the tonsils, base of tongue and uvula) have steadily increased in recent years, according to the National Cancer Institute, especially among men. At the same time, the incidence of oropharyngeal cancers related to other causes, such as smoking or alcohol consumption, is declining. HPV is the most common sexually transmitted infection in the United States; it can spread through direct skin-to-skin contact during vaginal, anal and oral sex. The UC Davis study, conducted by Allen Chen, associate professor in the UC Davis Department of Radiation Oncology, examined patterns of tumor reduction during radiation treatment in two otherwise similar groups of patients with oropharyngeal cancer: those who tested positive for HPV and those who tested negative for the virus. None of the HPV patients in the study was a smoker, a leading risk factor for the disease. Chen used CT scans acquired during image-guided radiation therapy (IGRT) and endoscopy (a tube with a small camera) to capture 3D images of the patients' tumors and monitor their treatment progress.

Robotic Surgery Through The Mouth Safe For Removing Tumors Of The Voice Box, Study Shows

Source: HealthCanal.com COLUMBUS, Ohio – Robotic surgery though the mouth is a safe and effective way to remove tumors of the throat and voice box, according to a study by head and neck cancer surgeons at the Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James). Dr. Enver Ozer This is the first report in the world literature illustrating the safety and efficacy of transoral robotic surgery for supraglottic laryngectomy, the researchers say. The preliminary study examined the outcomes of 13 head and neck cancer patients with tumors located in the region of the throat between the base of the tongue and just above the vocal cords, an area known as the supraglottic region. The study found that the use of robot-assisted surgery to remove these tumors through the mouth took about 25 minutes on average, and that blood loss was minimal – a little more than three teaspoons, or 15.4 milliliters, on average, per patient. No surgical complications were encountered and 11 of the 13 patients could accept an oral diet within 24 hours. If, on the other hand, these tumors are removed by performing open surgery on the neck, the operation can take around 4 hours to perform, require 7 to 10 days of hospitalization on average and require a tracheostomy tube and a stomach tube, the researchers say. The findings were published recently in the journal Head and Neck. “The transoral robotic technique means shorter [...]

DNA alone inadequate to identify HPV-related cancers

Source: www.oncologypractice.com Author: Mary Ann Moon Testing for the presence of human papillomavirus DNA alone, especially using polymerase chain reaction methods, is not adequate to identify which head and neck squamous cell carcinomas are caused by the virus, according to two studies published online Sept. 18 in Cancer Research. Identifying HPV-driven malignancies is important because they respond better to treatment and have better outcomes than those unrelated to HPV infection. Indeed, treatment of head and neck squamous cell carcinoma (HNSCC) may soon be guided by the tumor’s HPV status, since trials are now underway to determine whether de-escalation of chemo- and radiotherapy is safe and effective in such patients. At present, however, the biomarkers that are best suited to making this identification are unclear. Case Series Assesses Biomarkers In the first study, researchers assessed the usefulness of four biomarkers in determining which HNSCCs in a case series were driven by HPV. They began by examining fresh-frozen tumor biopsy samples from 199 German adults diagnosed as having oropharyngeal squamous cell cancer between 1990 and 2008. The four biomarkers were HPV-16 viral load, viral oncogene RNA (E6 and E7), p16INK4a, and RNA patterns similar to those characteristic of cervical carcinomas (CxCa RNA), said Dr. Dana Holzinger of the German Cancer Research Center at Heidelberg (Germany) University and her associates. The simple presence of HPV DNA in a tumor sample was found to be a poor indicator of prognosis, likely because it often signaled past HPV infections or recent oral exposure, rather than [...]

Head and neck cancer rates for smokeless tobacco described

Source: Health News Observer September 16, 2012 | by Steven Rothrock MD Smokeless tobacco is tobacco that is not burned or smoked. Other terms used for smokeless tobacco include chewing tobacco, spitting tobacco, dip, chew, and snuff. Typically these products are held in the mouth until juices are built up and spit out. Spitless products are available and some people choose to swallow the juices instead. Nicotine, which can be addictive, and cancer-causing agents are absorbed through the mouth’s lining. While using smokeless tobacco has been associated with many different cancers, the magnitude of the risk has not been previously well described. This week, in an online edition of the International Journal of Cancer, researchers sought to identify the magnitude of the risk of developing head and neck cancer in those who used smokeless tobacco. Towards that goal, the risk of cancer was compared between 1,046 users and 1,239 non-users of smokeless tobacco. After adjusting for age, sex, race, education, cigarette smoking, and alcohol use, any use of smokeless tobacco was associated with a 20% increased risk of head and neck cancer. Use of smokeless tobacco for 10 or more years had a 320% higher rate of developing these cancers compared to those who never used these products. In addition to head and neck cancers, users of these products are at risk for other cancers (e.g. esophageal, pancreatic, kidney), heart disease, high blood pressure, pregnancy loss, premature birth or low birth weights, low sperm counts, not to mention tooth gum [...]

Rating HPV biomarkers in head, neck cancers

Source: www.sciencecodex.com Not all head and neck cancers are created equal. Those started by infection with the human papillomavirus are less often fatal than those with other causes, such as smoking. Detection of a reliable fingerprint for HPV could help patients avoid unnecessarily harsh treatment. A new study finds that while one popular biomarker for HPV is not a reliable predictor of mortality from the cancers alone, combinations of some biomarkers showed much more promise. "Everybody who has studied it has shown that people with virally associated disease do better," said Karl Kelsey, aprofessor of epidemiology and pathology and laboratory medicine at Brown University, and corresponding author of the study in Cancer Research. "There are now clinical trials underway to determine if they should be treated differently. The problem is that you need to appropriately diagnose virally related disease, and our data suggests that people need to take a close look at that." In the study, Kelsey and his multi-institutional team of co-authors measured the ability of a variety of biomarkers to predict mortality from head and neck squamous cell carcinoma (HNSCC). Their data came from hundreds of adult head and neck cancer patients in the Boston area that they have been tracking since late 1999. As part of that data set, they were able to look at blood serology and tumor tissue samples, and they interviewed participants about risk behaviors such as smoking and drinking. DNA alone not reliable One of the most important findings of the study, Kelsey [...]

Marilyn Baker: Are some diseases more equal than others?

Source: National Post On Sept. 30, thousands of people will participate in the Run for the Cure marathon. They will raise thousands of dollars for breast cancer research. The Canadian Breast Cancer Foundation website is a sea of pink and purple and shows many further upcoming events where people can get involved in fighting breast cancer: The Nite of Hope auction, garden parties, the Pink Ribbon Charity Ball. The viewer is overwhelmed by the sheer volume of the support. It reminds me of an email I received a few years ago from a dear friend who asked me to pledge support for a breast cancer walkathon. Her personal website stated that “together, we can beat breast cancer.” There were some stats on the disease, plus a little thermometer measuring how her pledges were doing. Seeing the pink ribbons raises many emotions in me. And, to be honest, one of them is anger. Please don’t get me wrong. I have more than a passing interest in breast cancer. I lost a dear sister-in-law to breast cancer. I have friends who live with the illness. I consider myself a lucky breast cancer survivor. So why am I upset? Simple. I’m jealous of all the attention paid to breast cancer when there are so many other cancers that could also benefit from public awareness. All cancers should be a priority. My breast cancer was caught by a screening mammogram. After a biopsy confirmed an invasive lobular carcinoma, I underwent a partial mastectomy and underarm [...]

Study will evaluate Panitumumab regimen in advanced SCCHN

Source: http://www.onclive.com/ Author: staff Canadian researchers are investigating standard fractionation radiotherapy with concurrent high-dose cisplatin versus accelerated fractionation radiotherapy with panitumumab in patients with locally advanced stage III and IV squamous cell carcinoma of the head and neck (SCCHN). The NCIC Clinical Trials Group has completed accrual for the randomized phase III study, which has a planned sample size of 320 patients with SCC of the oral cavity, oropharynx, larynx, or hypopharynx. The trial was launched in December 2008, and the Data Safety and Monitoring Committee recommended continuing the trial in October 2011. Patients assigned to arm I will undergo standard fractionation radiotherapy once daily, five days a week, for seven weeks; they will also receive cisplatin intravenously over one hour on days 1, 22, and 43 of radiotherapy. Participants assigned to arm II will undergo accelerated fractionation radiotherapy once or twice daily, five days a week, for six weeks; they will also receive panitumumab intravenously over 30-90 minutes one week prior to and on days 15 and 36 of radiotherapy. The primary endpoint is progression-free survival (PFS), while secondary endpoints include overall survival, local and regional PFS, distant metastases, adverse events, swallowing-related quality of life, functional swallowing outcomes, and economic assessments. The FDA has approved panitumumab under the brand name Vectibix for the treatment of patients with metastatic colorectal carcinoma with disease progression on or following chemotherapy regimens containing fluoropyrimidine, oxaliplatin, and irinotecan. Panitumumab is a human IgG2 kappa monoclonal antibody that binds specifically to human epidermal growth factor [...]

Predicting oral cancer

Source: www.dailyrx.com Oral cancers can occur anywhere in the mouth. As with any cancer, the sooner it’s found, the better. A new tool helps doctors know when oral cancer may be in a patient’s future. A recent study finds that a set of molecular markers can help judge which lesions in the mouth are most likely to turn into oral cancer. The Oral Cancer Prediction Longitudinal Study was conducted in Canada at the Oral Cancer Prevention Program at the BC Cancer Agency in Vancouver. "The results of our study should help to build awareness that not everyone with a low-grade oral premalignant lesion will progress to cancer," said Program Director, Miriam Rosin, PhD. "However, they should also begin to give clinicians a better idea of which patients need closer follow-up." Every year, cancer shows up in the mouths of nearly 300,000 people around the globe. Some of these start as spots – or lesions – in the mouth that have not yet become cancerous. It’s always been difficult to tell which of these pre-malignant lesions will progress to full blown cancer. In an earlier study, Rosin’s team had analyzed the DNA of tissue that eventually turned into oral cancer. This research provided a method for grouping patients according to risk. For this study, researchers examined pre-cancerous tissue from nearly 300 patients, who were followed over a period of years. These patients were placed into either low-, intermediate- or high-risk groups. Two additional DNA markers were used to zero in on [...]
