HPV infection may be linked to poor head and neck cancer survival rates in African Americans

Source: www.aacr.org Author: staff American Association for Cancer Research Hosts Press Conference on New Study A groundbreaking study in Cancer Prevention Research, a journal of the American Association for Cancer Research, suggests that having the human papillomavirus (HPV) improves survival in squamous cell carcinoma of the head and neck. Furthermore, African Americans had far less HPV infection than whites, which led to worse survival. "There is currently no consensus on why blacks fare worse with squamous cell carcinoma of the head and neck than whites, but this is the first clue that it may be biologic rather than related to issues of access, insurance or provider attitudes," said senior author Kevin Cullen, M.D., director of the University of Maryland Marlene and Stewart Greenebaum Cancer Center and professor of medicine at the University of Maryland School of Medicine. Cullen's research showed that median overall survival was more than threefold higher for whites (70.6 months) than for African Americans (20.9 months) who were treated with chemotherapy and radiation. When the researchers examined patients by HPV status, they found that HPV-negative patients had a median survival of 26.6 months, while the survival rate for HPV-positive patients could not be calculated because most were still alive. Overall, 4 percent of African American patients and 34 percent of white patients were HPV positive. Cullen said the survival difference was entirely due to HPV status, as survival rates were similar among HPV-negative patients.

Three-drug combination shows long-lasting survival benefit in head and neck cancer patients

Source: www.medicalnewstoday.com Author: staff Adding a third drug (docetaxel) to a standard two-drug initial chemotherapy regimen significantly improves the long-term survival of patients with head and neck cancer, reducing the likelihood of dying by 26% over 6 years. The long-term results of the TAX 324 trial published Online First in The Lancet Oncology, confirm that this three-drug regimen should become the standard of care for patients who are suitable for induction therapy. Every year, cancers of the head and neck are diagnosed in more than 40 000 people in the USA. Standard treatment for these patients involves combining radiotherapy and chemotherapy with or without surgery, and the addition of induction chemotherapy has been shown to prolong survival. However, the best ways of combining these treatments remains unclear. In recent years, cisplatin plus fluorouracil (PF) has become a standard induction chemotherapy combination and has been shown to significantly prolong survival. The TAX 324 trial was designed to establish whether the addition of docetaxel to initial chemotherapy with cisplatin and fluorouracil (PF) might help patients with locally advanced head and neck cancer live longer. Between May 1999 and December 2003, 501 patients were recruited from 55 centres across the USA, Canada, Argentina, and Europe. In 2007, initial results (minimum follow-up 2 years) showed that induction chemotherapy with docetaxel, cisplatin, and fluorouracil (TPF) significantly improved survival compared with PF. To establish the durability of this survival benefit, Jochen Lorch from the Dana-Farber Cancer Institute, Boston, USA and colleagues evaluated the long-term follow-up of [...]

Cel-Sci to bump standard of care in head, neck cancer

Source: www.bioworld.com Author: Catherine Shaffer Cel-Sci Corp. began a carefully designed Phase III trial of Multikine, its investigational immunotherapy for head and neck cancer. Because Multikine is designed to recruit the support of a mostly healthy immune system, Cel-Sci is making a headlong charge at the goal of first-line therapy, instead of trying to develop the product in patients who have already received surgery, radiation and chemotherapy, and have suppressed or damaged immune systems as a result. If Cel-Sci can prove the therapy works in the narrow three-week testing window granted by the FDA, Multikine stands to replace a standard of care that has changed little in half a century. "It makes no sense to develop an immunotherapy product for late-stage patients. You should develop it as a first line therapy, ahead of radiation or chemotherapy," Cel-Sci CEO Geert Kersten told BioWorld Today. Vienna, Va.-based Cel-Sci's clinical trial plan takes advantage of a nearly inevitable delay of up to six weeks between diagnosis and surgery in most head and neck cancers. The FDA has allowed Cel-Sci a three-week period to give Multikine to patients before they commence with surgery, radiation, and chemotherapy. This will not deprive any patients of the best possible standard-of-care while they also try an experimental therapy. Head and neck cancer strikes about 500,000 people annually worldwide. Some causal factors include smoking, drinking and chewing tobacco. Most cases are diagnosed outside the U.S., and about two-thirds of patients appear with advanced disease. The standard treatment for it [...]

Robotic tongue cancer surgery-Mayo Clinic

Source: www.theze.cn Author: staff Fighting cancer is not easy. Chemotherapy, radiation and surgery can be very hard on your body. Take head and neck cancers, for example. These tumors are often hard to reach. Doctors have to cut through bones such as your jaw to reach them. Now, doctors at Mayo Clinic are using robots to access these cancers through your mouth, leaving face bones intact.

Good speaking, swallowing after chemoradiotherapy for head/neck cancer

Source: www.medscape.com Author: Fran Lowry Most patients with locoregionally advanced head and neck cancer who were successfully treated with intensive chemoradiotherapy had no residual deficits in speaking or swallowing after their treatment, according to the results of a study done by University of Chicago researchers. The study appears in the December issue of the Archives of Otolaryngology–Head & Neck Surgery. Of 163 patients with head and neck cancer who were assigned a speaking score an average of 35 months after completing treatment, 84.7% were found to have no lasting difficulties and were given a score of 1 on a scale of 1 to 4, with 1 being the best and 4 being the worst function. In addition, among 166 patients who were assigned a swallowing score an average of 35 months after treatment, 63.3% were found to have no lasting difficulties swallowing and were given a score of 1. "We weren't surprised by our findings," senior author Joseph K. Salama, MD, told Medscape Medical News. "However, it was nice to quantify formally our clinical impressions—that most patients in the long run do well." Dr. Salama was with the University of Chicago, Illinois, at the time the study was conducted and is now at Duke University Medical Center in Durham, North Carolina. Expert Disagrees However, Robert L. Ferris, MD, PhD, professor and vice chair of the Department of Otolaryngology at the University of Pittsburgh Medical Center in Pennsylvania, disagreed with the view that so many patients with head and neck cancer [...]

Real Cancer Drug Breakthrough Is Astronomical Prices

Source: Robert Langreth Blog In the wake of the FDA’s decision start the process to revoke Avastin’s approval in breast cancer last week, patients are puzzled and angry over how a drug once touted as a breakthrough now can be branded as ineffective. The controversy illustrates just how much the much-vaunted revolution in cancer therapy is driven by hype and high prices. Selling cancer drugs has become big business, with $52 billion in sales last year, according to IMS. Some $6 billion of it goes right to Roche’s Avastin, the biggest selling of the new drugs. No wonder companies like Merck and Pfizer are racing to develop new cancer drugs. But even as sales reach new heights, and prices keep going up–pretty much any cancer drug now costs $50,000 a year–the results from many trials are getting less and less impressive. Tarceva from Roche extends the life of pancreatic cancer patients by two weeks. Avastin has now failed to extend the lives of breast cancer patients in three giant trials. The hype about targeted cancer drugs has reached fever pitch thanks in part to baby boomers who don’t want to acknowledge their mortality; companies who need to sell hugely expensive drugs that can cost up to $100,000 a year; and science journalists eager for a positive story about a dread disease. The truth is that nobody wants to acknowledge the unpleasant fact that progress against most cancers has been grudgingly slow. Oncologists are in the business of providing hope to [...]

Hospital Performs Area’s First Robotic Surgeries on Oral Cancers HEALTH CARE: Technique Could Reduce the Length Of Patients Hospital Stay

Source: San Diego Business Journal By: Steve Sinovic The first transoral robotic surgeries in San Diego have been performed at Sharp Chula Vista Medical Center and all three patients who underwent those procedures are recovering well, said the surgeon who is leading up the effort to help patients beat early-stage oral cancer. Advances in robotic surgery prompted the hospital to look for ways to apply that technology to treat tumors of the mouth and throat. And thanks to a local benefactor, the institution hopes to be performing more procedures on local patients. The hospital is one of fewer than a dozen in the U.S. to offer the procedure, which was launched thanks to a $1.2 million anonymous donation to Sharp Chula Vista. The donation helped fund the acquisition of Intuitive Surgical Inc.’s da Vinci Surgical System, said Dan Dredla, vice president of business development for the 343-bed hospital in south San Diego County. “We were fortunate that a donor helped us purchase the da Vinci,” said Dredla. “It’s a costly system, and it was challenging to find the capital to acquire it on our own.” The da Vinci robot, which combines enhanced 3-D views with precise incision capabilities, is already being used for various surgeries at hundreds of hospitals throughout the country and around the world. However, it was just recently that the U.S. Food and Drug Administration approved using the da Vinci for the transoral surgeries, or TORS, procedures on head and neck cancers. While Dredla didn’t have exact [...]

Zometa aids patients with head and neck cancer

Source: DrBicuspid.com Zoledronic acid, a drug currently approved for osteoporosis treatment, has been shown to reduce bone loss in a study of mice with oral cancer, suggesting it could serve as a supplemental therapy in patients with head and neck cancers that erode bone (Cancer Research, November 1, 2010, Vol. 70:21, pp. 8607-8616). The drug, known by the brand name Zometa, is designed to inhibit bone resorption. Oral squamous cell carcinoma accounts for about 90% of all tumors in the mouth, according to the National Cancer Institute. The five-year survival rate for this form of cancer is 61% for all stages combined. When these tumors form in the gums, their growth in the mouth leads to bone loss in the jaw. In turn, bone erosion stimulates the cancer to grow. Scientists call this phenomenon, driven in part by the release of cancer stimulatory compounds from bone, a vicious cycle that occurs in this and other forms of cancer. Even though the bone loss itself is not life-threatening, loss of bone means the tumor is continuing to grow. "The goal is to stop the vicious cycle," said Thomas Rosol, DVM, PhD, professor of veterinary biosciences at Ohio State, in a press release. "Chemotherapy, radiation, and surgery are all used to treat head and neck cancers. Zoledronic acid is a very safe drug and all it does is block bone resorption, so patients could receive all of the standard treatments, and this drug could be added as an additional benefit. That's the [...]

Michael Douglas Fights Oral Cancer

Source: The Science of Dentistry Actor Michael Douglas‘ recent revelation that he has stage IV oral 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 includes a walnut-sized tumor at the base of his tongue, and he will require radiation therapy, chemotherapy, and surgery. Douglas says his doctors told him he has an 80% survival rate if it hasn’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 (HPV). HPV are common viruses that cause warts. 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. 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. This is why an opportunistic screening by the dental community [...]

My dog saved my life, says Sunderland man

Source: Sunderland Echo By: Katy Wheeler John and Pauline Douglas were devastated when their dog Diesel had to be put down after developing cancer of the neck. But it was the late bull mastiff’s symptoms which helped John, 39, realise that he too had the disease. The dad-of-four, of Tunstall Bank, noticed a lump in his neck in February. And despite the fact he was told by doctors to rule out cancer, John’s experience with Diesel’s disease convinced him something was seriously wrong – and he pushed for further tests. His instincts were proved correct and John was diagnosed with cancer, which had spread to his neck, in April – just a week before his wedding day to wife Pauline, 41. John said: “Because of my age, the fact I don’t smoke and because I am a moderate drinker, I was told not to worry about cancer and that it was just an infection. “But what happened to Diesel set alarm bells ringing. “He had the same kind of lump in his neck that would swell up and down. We were told his wasn’t cancer to start with and it was only found late on. “Even though I was told by a specialist that I didn’t fit the criteria for cancer, the doubt was still niggling and I made such a song and dance that more tests were done.” As a result of John’s persistence, one of his tonsils was removed and a biopsy revealed the cancer, which had spread [...]
