Johnson & Johnson Sued for $70 Million Over Oral Cancer Test Detection

Source: Dr.Bicuspid.com July 8, 2011 -- Oral Cancer Prevention International (OCPI), makers of the Oral CDx brush test for oral cancer detection, is suing Johnson & Johnson (J&J) over a terminated distribution contract with OraPharma. OraPharma was previously a subsidiary of J&J until it was acquired last December by Water Street Healthcare Partners, a private equity firm in Chicago. J&J, which among other things sells Listerine mouthwash, was worried that a 2008 study linking alcohol-containing mouthwashes with oral cancer would negatively affect sales of Listerine and allegedly induced OraPharma to breach the sales agreement, according to OCPI. The lawsuit, filed July 6 in U.S. District Court, District of New Jersey, claims that J&J "maliciously and fraudulently" interfered with a contract between OCPI and OraPharma that gave OraPharma exclusive rights to sell the test to U.S. dentists. J&J's interference caused OraPharma "to suppress sales of and withhold from the public a proven lifesaving oral cancer prevention product in order to protect sales of its mouthwash, Listerine, which has been linked to oral cancer," according to the complaint. After OCPI signed the contract in February 2010, J&J did not want to "lend credence to the link between Listerine and oral cancer" by selling both its mouthwash and OralCDx, the complaint states. As of press time, J&J did not return calls for comment by DrBicuspid.com. Sales of Listerine bring in more than $1 billion per year, the suit claims. OralCDx is a "quick, painless, and inexpensive test that can prevent oral cancer by [...]

What Really Killed Farrah Fawcett?

Source: Empowher.com In a recent interview between CNN’s Piers Morgan and Ryan O’Neal, O’Neal claimed that the stress resulting from his family turmoil may have contributed to Farrah Fawcett’s death. He stated,“…we really don’t know what causes cancer…” When it comes to anal cancer, the disease that took Fawcett’s life in June of 2009, we certainly do know the cause. More than 90 percent of anal cancers are the result of Human Papillomavirus (HPV). This is the same virus responsible for cervical, vulvar, vaginal, penile and oral cancers. The list of cancers resulting from HPV continues to grow, with oral cancer (mainly affecting men) as the latest on the ongoing list. It has been known for quite some time, however, that HPV is responsible for anal cancer. Over the past three decades, anal cancer has risen among women by 78 percent, and it has risen among men by 160 percent. Those figures were taken from a study done in 2004 by the Fred Hutchinson Cancer Research Center in Seattle, Washington. It has been another seven years, and still, little is done to inform the public of this rapidly growing trend and the vaccine that can prevent the two most aggressive strains of HPV known to cause anal cancer. When Fawcett’s documentary regarding her diagnosis and treatment for anal cancer aired in 2009, anal cancer survivors and others with HPV watched intently. They wanted to see if there would be a public service announcement at the end of the documentary to [...]

Michael Douglas Continues to Put Oral Cancer in the Spotlight

Source: Dr.Biscupid.com Actor Michael Douglas' recent revelation that he had stage IV oropharyngeal cancer has highlighted the growing incidence of oral cancer, and experts say dentists can help stem the alarming increase of the disease by checking for it during routine examinations. The actor's cancer included a walnut-sized tumor at the base of his tongue, requiring radiation therapy, chemotherapy, and surgery. Douglas says his doctors told him he had an 80% survival rate if it hadn't spread to his lymph nodes. While tobacco was the prime cause of oral cancer in the past, recent studies have attributed the steady increase of the disease to the human papillomavirus (HPV16). There are approximately 130 versions of HPV but only nine cause cancers, and the HPV16 version causes almost half of the oral cancers in the U.S., said Brian Hill, executive director of the Oral Cancer Foundation. "Tobacco is no longer the only bad guy," he told DrBicuspid.com. “HPV16 is increasing in incidence as the causative etiology, and if it continues on this trend line, it will replace tobacco as the primary cause of oral cancers." Dentists can play a key role in catching the disease in its early stages if they check for it during examinations, Hill pointed out. "But many dentists think it's such a rare disease that they don't bother to screen for it," he said. "Most Americans have never even heard of oral cancer, but it's not as rare or uncommon as people would like to think it is. [...]

Oral, Head and Neck Cancers Continue to Increase While Most U.S. Cancer Death Rates are on the Decline

Source: SHOTS (NPR's Health Blog) The rate at which Americans die from cancer continues to fall, according to the latest estimates from the American Cancer Society. As a result, nearly 900,000 cancer deaths were avoided between 1990 and 2007, the group figures. Survival gains have come as mortality rates have declined for some of the most common malignancies, including colorectal cancer, breast cancer in women and prostate cancer. Still, the ACS estimates there will nearly 1.6 million new cancers diagnosed this year, and about 572,000 deaths from the disease. The incidence of cancers hasn't budged much for men in recent years, after falling quite a bit during the first half of the last decade. Cancer incidence for women has been falling since 1998. The report was just published online by CA: A Cancer Journal for Clinicians. Lung cancer remains the biggest killer for both men and women. All told, about 160,000 people in the U.S. are expected to die from it this year. Starting in 1987, more women have died from lung cancer each year than breast cancer. One section of the report focuses on a persistent and, in some cases, widening gap in cancer death rates between people with the least education and those with the most. Educational attainment is often used in research as a proxy for socioeconomic status. American Cancer Society epidemiologist Elizabeth Ward, one of the report's authors, tells Shots, "People of a lower socioeconomic status are more likely to smoke and less likely to get [...]

Glowing Cornell Dots Target Cancer

SOURCE: Journal of Clinical Investigation, June 13, 2011 (Ivanhoe Newswire)-- New medical technology is showing that Cornell dots may be a potential cancer diagnostic tool. The U.S Food and Drug Administration (FDA) has recently approved the first clinical trial in humans using Cornell Dots- brightly glowing nanoparticles that can light up cancer cells in PET-optical imaging. Cornell Dots are silica spheres less than eight nanometers in diameter that enclose several dye molecules. To make the dots stick to tumor cells, organic molecules that bind to tumor surfaces, or even specific locations within the tumors, can be attached to a polyethylene glycol shell. This shell, also referred to as PEG, prevents the body from recognizing the dots as foreign substances. When exposed to near-infrared light, the dots fluoresce much brighter than dye to serve as a beacon identifying the target cells. Researchers say this technology enables visualization during surgical treatment. Cornell Dots were first developed in 2005 by Hooisweng Ow, a coauthor of the paper on this study and once a graduate student working with Ulrich Wiesner, Cornell Professor of Materials Science and Engineering. Ow and other researchers of this technology are currently in the process of forming a new commercial entity in New York City that will help transition this research into commercial products that will benefit cancer patients. Michelle S. Bradbury, M.D, of the Memorial Sloan-Kettering Cancer Center and an assistant professor of radiology at Weill Cornell Medical College, was quoted as saying, "This is the first FDA IND approved [...]

HPV related oral cancers continue to increase in the US

Source: International Medicine News CHICAGO – Human papillomavirus infection was firmly linked to the recent rise in oropharyngeal cancers in the United States, based on data from the National Cancer Institute’s Surveillance, Epidemiology, and End Results program. If current trends continue, the incidence of HPV-related oral cancers will soon surpass that of cervical cancers, senior author Dr. Maura Gillison reported at the annual meeting of the American Society of Clinical Oncology. The incidence of HPV-positive oropharyngeal cancers increased 225% – from 0.8 per 100,000 to 2.8 per 100,000 – between 1988 and 2004, the researchers found. At the same time, the incidence rate for HPV-negative oropharyngeal cancers, which are strongly related to tobacco and alcohol use, declined by 50% – from 2.0 per 100,000 to 1.0 per 100,000. Consequently, the overall incidence of oropharyngeal cancers increased 28%. Even by the conservative estimate that 70% of oropharyngeal cancers in 2020 will be HPV positive, the annual number of HPV-positive oral squamous cell carcinomas (8,653 cases) is expected to surpass cervical cancers (7,726 cases). Further, the majority will occur among men (7,426 cases), said Dr. Gillison, a medical oncologist and the Jeg Coughlin Chair in Cancer Research at Ohio State University Comprehensive Cancer Center in Columbus. Changes in sexual behavior among recent birth cohorts and increased oral HPV exposure probably influenced the increases in incidence and prevalence, Dr. Gillison speculated. Having a high lifetime number of sexual partners is a known risk factor for HPV infection. Although the rise in oral cancers [...]

Head and Neck Cancers Linked to HPV are on the Rise

Source: The Wall Street Journal A form of head and neck cancer associated with the sexually transmitted human papillomavirus is on the rise, especially in men, the WSJ reports. Fast-rising rates of oropharyngeal cancer — tumors in the tonsil and back-of-the-tongue area — have been linked to changes in sexual behavior that include the increased practice of oral sex and a greater number of sexual partners. But HPV-positive cancer has also been reported in individuals who report few or no sexual partners. It may also be possible for the virus to be transmitted to an infant via an infected mother’s birth canal. An HPV vaccine is routinely recommended for girls because the virus can cause cervical cancer. The rise in HPV-positive head and neck cancers is leading to a new focus both on treatment of the disease, and whether recommending routine vaccination for boys could prevent oral infections and cancers. (A CDC advisory panel said in 2009 that it was fine for boys to get the vaccine, but recommended against routine administration.) Eric Genden, chief of head and neck oncology at Mt. Sinai Medical Center, tells the Health Blog that when treated appropriately, patients with HPV-positive cancers have an 85% to 90% disease-free survival rate over five years. By contrast, patients with HPV-negative head and neck cancers, which are often associated with smoking and drinking, typically have more advanced disease when the cancer is detected and face a five-year survival rate of only 25% to 40%, Genden says. HPV-induced head [...]

Pan-Canadian Surgical Study Offers New Hope for Patients With Early-Stage Oral Cancer

Source: Canada NewsWire VANCOUVER, May 26, 2011 /CNW/ - Currently, about 30 per cent of patients who receive oral surgery have their cancer recur. But a new, Canada-wide surgical trial using a new approach to remove tumours and pre-cancerous cells from the mouths of those diagnosed with early-stage oral cancer offers new hope for patients. The Terry Fox Research Institute (TFRI) announces the launch of a $4.7 million Pan-Canadian Phase III clinical trial aimed at improving outcomes for patients undergoing surgery for oral squamous cell cancers. The Canadian Optically Guided Approach for Oral Lesions Surgical Trial (The COOLS Study) has the potential to revolutionize clinical practice here and around the world for this kind of cancer. "Our investment in this promising study is our response to a serious clinical concern expressed by head and neck surgeons across Canada and it has the potential to change surgical practices for cancer of the mouth nationally and internationally," said Dr. Victor Ling, TFRI President and Scientific Director. Using a new surgical approach guided by an existing hand-held light tool, the surgeons, pathologists, and scientists involved in this nine-centre study will determine whether recurrence is reduced when they shift the surgical field for the removal of tumours or pre-cancerous cells in the mouth. The surgeons will use fluorescence visualization (FV) or "blue light" provided by the optical aid rather than traditional white light to determine the tissue to be removed. Under the blue light, normal tissue generates a fluorescence which is absent in tumour [...]

Clinicians support the necessity of neck dissection because of high risk of recurrence in oral cancer patients

Source: HighWire Stanford University PURPOSE: In head and neck cancer, the most important prognostic factor is the presence or absence of neck metastasis. Although still debated in the published data regarding the "wait and see" policy for Stage T1-T2 oral cancer, a large number of clinicians support the necessity of neck dissection, especially in cases of oral tongue carcinoma, because of the poor prognosis and high risk of recurrence. The aim of the present study was to summarize and quantify the incidence of occult metastasis in oral cancer treatment at the oral and maxillofacial surgery department, Rambam Medical Center, in the past 10 years. PATIENTS AND METHODS: A total of 142 neck dissections performed at our department in the past 10 years (1998 to 2009) and a series of 68 patients (44 men and 22 women) treated for Stage T1N0 or T2N0 oral cancer were included in the present retrospective study. All patients underwent surgical resection of the oral cancer and selective neck dissection of the ipsilateral side. RESULTS: Occult lymph node metastases were detected in 11 patients (16% overall, 9 in the tongue, 1 in the buccal mucosa, and 1 in the gingiva of the mandible). The frequency of occult metastasis from tongue carcinoma was 34% (9 of 26 cases). The 5-year survival rate in the present study was 78.9%. In patients who underwent chemotherapy, radiotherapy, brachytherapy, or a combination of the 3 after surgical management, the overall survival rate decreased significantly to 22.5% (P = .006, log-rank test).
