Port Coquitlam dentist hopes to save a life with a Velscope

Source: www.bclocalnews.com Author: Diane Strandberg A Port Coquitlam dentist is offering to do more than fix cavities and polish teeth. Dr. Glenn Keryluk wants to save a life. He's purchased an oral cancer screening device he expects will shortly become standard equipment in all dentist offices and he is offering to screen patients referred to by local doctors. "It's the latest and greatest in cancer detection," Keryluk says of the Velscope, a hand-held device that shines a blue light on oral lesions that could be cancerous. Manufactured by a White Rock-based company, the Velscope can show abnormal tissue below the surface, even before it becomes apparent to the clinicians' eye. Healthy tissue glows green under the light but cancerous tissue looks black. Being able to detect oral cancer early is key to surviving the disease because the longer the cancer is around the more likely it will spread to nearby organs. Keryluk held a free screening day for patients at his office at 2099 Lougheed Highway recently and is cutting standard fees for the procedure or waving them entirely for people without dental coverage. The procedure is painless, takes only a few minutes and a photograph of the lesion taken by the machine can be sent to a physician for follow-up. "If you catch it early it could be that a person's life is saved. I just want people to be aware of the technology out there," Keryluk said. He's only seen two cases of oral cancer in 20 years [...]

Identification of highly radiosensitive patients may lead to side effect-free radiotherapy

Source: www.ecancermedicalscience.com Author: staff An international group of scientists has taken the first step on the road to targeting radiotherapy dosage to individual patients by means of their genetic characteristics, a radiation oncologist told Europe’s largest cancer congress, ECCO 15 – ESMO 34, in Berlin today. Professor Dirk de Ruysscher, from Maastricht University Medical Centre, Maastricht, The Netherlands, said that his team’s work might provide the basis for personalised radiotherapy in which, with a simple blood test, doctors may be able to select the optimal radiation dose for a particular patient. The team of scientists from The Netherlands, Belgium, Germany, and Canada studied a group of patients with hypersensitivity to radiation therapy, drawn from the largest world-wide database available – the European Union-funded Genetic pathways for the prediction of the effect of irradiation (GENEPI) study, which integrates biological material with patient data and treatment specifications. The database included information from more than 8000 European patients. “Part of this project is the establishment of a sub-database in which very rare patient characteristics are brought together with the hypothesis that their genetic traits will enable the characterisation of molecular pathways related to radio-sensitivity,” explained Professor de Ruysscher. “A major problem for radiation oncologists at present is that we are bound by the need to avoid damage to normal tissues. This means that the dose of radiation generally used is governed by the response of the most radiosensitive patients, and this may lead to many patients receiving lower than optimal doses, hence affecting [...]

Induction with Docetaxel, Cisplatin, and 5-FU provides survival benefits beyond 5 years in head and neck cancer

Source: www.docguide.com/news Author: Chris Berrie Induction with docetaxel, cisplatin, and 5-fluorouracil (5-FU) provides sustained significant survival advantages beyond 5 years compared with cisplatin and 5-FU in patients with locally advanced squamous cell cancer of the head and neck. Jochen Lorch, MD, Head and Neck Oncology Programme, Dana Farber Cancer Institute, Harvard University, Boston, Massachusetts, presented a 5-year follow-up analysis of the multicentre, randomised, open-label, phase 3 Cisplatin and Fluorouracil Alone or With Docetaxel in Head and Neck Cancer (TAX 324) at the joint 15th Congress of the European Cancer Organisation (ECCO) and 34th Congress of the European Society for Medical Oncology (ESMO). The benefits of docetaxel in combination with cisplatin and 5-fluorouracil (TPF) was shown in the original TAX 324 and TAX 323 studies. Results of the follow-up were presented here on September 22. TAX 324 included 501 patients with measurable, nonmetastatic stages III and IV squamous cell carcinoma of the head and neck, with a primary tumour location in the oral cavity, oropharynx, larynx or hypopharynx, and unresectable disease. A World Health Organization (WHO) performance status (PS) of 0/1 and no prior chemotherapy or radiotherapy were also specified. Patients were randomised to induction therapy of TPF (n = 255) or cisplatin plus 5-fluorouracil (PF) on days 1 to 4, every 3 weeks for 3 cycles (n = 246). The induction treatments were followed by chemoradiotherapy with carboplatin area under the curve (AUC) 1.5, weekly and daily radiotherapy (5 days/week). In the original study, there was a significant 13% improvement [...]

For Apple, accessibility is much more than lip service

Source: arstechnica.com/apple/news Author: Chris Foresman We have discussed the advancements Apple has made in accessibility to Mac OS X and even the iPhone in the past, but recent examples show that Apple's attention to detail in technologies technologies like VoiceOver and Voice Control can make all the difference in the world for users with speech or sight impairments. These technologies are earning Apple awards and the appreciation of users and further separate Apple from the competition. It was just a few weeks ago when we noted comments from industrial designer Mike Calvo, whose company Serotek is involved in accessibility design, on how well accessibility is engineered into the iPhone. "Apple understands that accessibility should be about far more than developing custom solutions which pay lip service to the idea of accessibility but detract from the out-of-box experience enjoyed by everyone else," he wrote in his assessment of the iPhone. Now, after the release of iPhone OS 3.1, the Mac-cessibility Network noted that Apple has added an additional 16 improvements to the accessibility features of Apple's mobile devices. These include controls for cutting and pasting text or even editing video using VoiceOver and Voice Control, reading PDF files, and using Voice Control over a Bluetooth headset. The continued attention to detail shows that Apple doesn't take accessibility lightly. This attention to detail has also earned Apple an award from the National Federation for the Blind. Tomorrow, during its first ever Web Accessibility Day conference, the NFB will give an award to [...]

Initial COIN study results presented at European Oncology Congress

Source: Drugs.com Author: Staff • Results inconsistent with data from all Erbitux pivotal studies • Further analyses planned by the Medical Research Council that conducted the independent COIN study Berlin/Darmstadt, Germany, September 23, 2009 – The Medical Research Council (MRC), a UK-based, publicly-funded organization dedicated to improving human health, today presented the initial results of the independent Phase III COINa study, which did not meet its primary endpoint of overall survival (OS).1 These findings were presented today at the joint 15th Congress of the European Cancer Organisation (ECCO) and 34th Congress of the European Society for Medical Oncology (ESMO) in Berlin, Germany. The COIN study was designed to evaluate whether the addition of Erbitux® (cetuximab) to one of two oxaliplatin-based chemotherapy regimens significantly improved outcomes in previously untreated metastatic colorectal cancer (mCRC) patients with KRAS wild-type tumors. The median OS was not statistically significant at 17.0 months in the Erbitux treatment arm compared to 17.9 months for the chemotherapy-alone group (hazard ratio [HR] 1.038; p=0.68).1 “Imbalances in the chemotherapy administered between the different study arms were reported previously in the interim safety analysis,” explained Dr. Wolfgang Wein, Executive Vice President, Oncology, Merck Serono, a division of Merck KGaA, Darmstadt, Germany. “Further analysis of the dose intensity and 2nd-line treatment, and other factors, such as the advanced disease of patients in the study, are ongoing to determine why the COIN results are not aligned with existing evidence from the other randomized, 1st-line studies, including the significant increase in overall survival achieved with the CRYSTAL study.” Results [...]

A different camel is back in the glossies

Source: nytimes.com Author: Andrew Adam Newman The two largest tobacco companies in the United States voluntarily stopped advertising cigarettes in magazines, with Philip Morris, whose brands include Marlboro, ceasing in 2005 and R. J. Reynolds, whose brands include Camel, at the beginning of 2008. Now the Camel logo is back prominently in major glossies, including Rolling Stone, Sports Illustrated and Maxim — but not to advertise cigarettes. R. J. Reynolds is advertising Camel Snus, a tobacco packet that wedges in the upper lip and, unlike chewing tobacco, is promoted as “spitless” because low salt content spares users the unpleasantness of public expectoration. Although snus is popular in Sweden, this is the first time it has been marketed in the United States by a major American tobacco company. The campaign, by Quaker City Mercantile in Philadelphia, pitches Camel Snus (pronounced snoose) as a way around smoking bans. The ads cater to specific magazine audiences, with a recent issue of Rolling Stone promoting snus as “sweaty outdoor festival friendly” and one in Sports Illustrated declaring it “extra inning friendly.” Others call snus “your flight just got canceled friendly,” “ridiculously long conference call friendly” and “fancy hotel friendly.” David Howard, an R. J. Reynolds spokesman, said that the company had not reversed its magazine policy, but that this was a Camel of another color. “We do not advertise cigarettes in print right now and have not done that for a couple years, but Camel Snus is not a cigarette,” Mr. Howard said. “This [...]

Charting the path from infection to cancer

Source: www.cancer.gov/ncicancerbulletin Author: Eleanor Mayfield Few people associate infection with cancer, but close to one-fifth of all cancers in the world are caused by infectious agents, including viruses, bacteria, and other microbes. In developing countries, the number is higher—about one in four—while in industrialized countries, such as the United States, it is about one in 12. Infectious agents that can cause cancer are extremely common, infecting millions of people around the world. Yet it is rare and takes a long time for an infection to develop into cancer. “You need a lot of things to happen, or not happen, to get from an infection to cancer,” said Dr. Douglas R. Lowy, chief of NCI’s Laboratory of Cellular Oncology and a leader in the molecular biology of tumor viruses. The microbes responsible for most of the global burden of infection-associated cancer are: the bacterium Helicobacter pylori, which causes gastric cancer; cancer-causing strains of the human papillomavirus (HPV), which cause cervical cancer and other cancers; and the hepatitis B and C viruses, which cause liver cancer. These four microbes alone cause more than 15 percent of all cancers worldwide. Other cancers known to be associated with infectious agents include leukemia and lymphoma; anal, penile, vaginal, and vulvar cancer; and tongue and throat cancers. Last week, researchers reported new evidence linking aggressive prostate tumors to a virus. Role of the Immune System Microbes can lead to cancer by a variety of mechanisms that are not yet fully understood, explained Dr. Allan Hildesheim, chief [...]

Flavored cigarette ban takes effect 9/22

Source: MSN.com Author: Karen Pallarito New federal law may help deter young smokers, health advocates say TUESDAY, Sept. 22 (HealthDay News) -- Young people who enjoy a hint of vanilla, berry or chocolate when they light up are about to have their favorite smokes snuffed out. A new federal law banning fruit- and candy-flavored cigarettes takes effect Sept. 22. The prohibition is part of the Family Smoking Prevention and Tobacco Control Act, legislation that grants the U.S. Food and Drug Administration the authority to regulate tobacco products. President Barack Obama signed the measure into law June 22. Studies show that flavored cigarettes, which have been around for about a decade, disproportionately appeal to America's youth. Thus, banning the manufacture and sale of kid-friendly flavored cigarettes is a critical step toward deterring young smokers, health advocates said. "Almost 90 percent of adult smokers start smoking as teenagers. These flavored cigarettes are a gateway for many children and young adults to become regular smokers," FDA Commissioner Dr. Margaret A. Hamburg said in a news release. "The FDA will utilize regulatory authority to reduce the burden of illness and death caused by tobacco products to enhance our nation's public health." Gregg Haifley, associate director of federal relations for the American Cancer Society Cancer Action Network in Washington, D.C., said, "Banning candy and fruit flavorings in cigarettes can have a significant effect on the reduction of initiation of smoking among youth, as well as reducing the number of youth who go on to regular, [...]

Prospective analysis of outcomes and complications of 300 consecutive microvascular reconstructions

Source: Arch Facial Plast Surg. 2009;11(4):235-239 Authors: Michael J. Nuara, MD; Cara L. Sauder, MA, CCC-SLP; Daniel S. Alam, MD Objective: To prospectively follow up patients requiring microvascular reconstruction of head and neck defects to determine preoperative factors predictive of surgical complications. Methods: A prospectively collected database comprising 300 consecutive microvascular head and neck reconstructions performed by a single surgeon (D.S.A.) in a tertiary care hospital over a 6-year period was reviewed in a retrospective manner. Data collected included preoperative medical and surgical history (presence of documented cardiac disease, diabetes mellitus, and hypertension) and previous cancer treatment (surgery or radiation therapy). Postoperative data, including early or late complications, hematocrit during hospitalization, and functional status, were also collected. A multiple linear regression was used to identify predictors of surgical complications and secondarily crossed to determine the strength of the prediction. Statistical significance was set at P = .05. Results: Patients were stratified into 4 groups based on (1) previous radiation therapy, (2) previous surgery, (3) no previous radiation therapy or surgery, and (4) both previous radiation therapy and previous surgery, with an increased predictability of complications with both. Diabetes also added to the predictability of complications, with a smaller effect. Cardiac disease and hypertension were not predictive. Conclusions: Previous radiation therapy and surgery are positive predictors for wound complications after microvascular reconstruction. Diabetes may add further risk in this setting.

Ultrasonography-guided fine-needle aspiration for the assessment of cervical metastases

Source: Arch Otolaryngol Head Neck Surg. 2000;126:1091-1096 Authors: Marco Knappe, MD et al. Objective: To assess the value of ultrasonography (US) combined with fine-needle aspiration (FNA) cytology for the investigation of lymph node metastases in patients with head and neck cancer. Design: Comparison of clinical examination (palpation) and preoperative US-FNA examination results of cervical nodes in a sample of patients with head and neck cancer. The histological features of the neck dissection specimens are used to validate these 2 variables. Setting: A head and neck oncology service in a tertiary referral hospital. Patients: A consecutive sample of 56 patients with head and neck squamous cell carcinoma, first seen between April 1, 1996, and July 30, 1998, who had neck dissections performed after the US-FNA examination. Intervention: Cervical US-FNA preoperatively, followed by elective or therapeutic radical modified or selective neck dissection. Main Outcome Measures: The histological examination results of subsequent neck dissection specimens are used to determine the sensitivity, specificity, and accuracy of US-FNA for individual nodes. Second, the results of node staging by clinical examination and US-FNA examination are compared. Results: The sensitivity was 89.2%; specificity, 98.1%; and accuracy, 94.5%. Correct node stages were obtained in 52 (93%) of the patients using US-FNA compared with 34 (61%) using palpation. Conclusions: Ultrasonography combined with FNA is a highly accurate technique for the investigation of cervical lymph node metastases. A more accurate diagnosis may result in more appropriate treatment, particularly in a setting with limited resources. Retropharyngeal nodes, micrometastases, and lymph nodes [...]
