Drug Target in Rare, Lethal Glandular Cancer Discovered

Source: www.dddmag.comAuthor: Yale University  Using a novel cell culture approach, Yale Cancer Center researchers have discovered critical vulnerabilities in adenoid cystic carcinoma (ACC), a rare and lethal glandular cancer with a high recurrence rate and few treatment options. The findings, published April 15th in the journal Clinical Cancer Research, offer data that ACC and similar cancers could be treated with already available drugs. ACC most often occurs in the salivary glands but can originate in the breast, trachea, skin, or other sites. Survival rates at five years are close to 90percent but drop significantly after that with just 40percent surviving at 15 years after diagnosis. It is a slow-growing cancer that affects about 1,200 people each year, with few symptoms in early stages. Aside from surgery, there are few treatments for ACC, which until now has proven largely resistant to radiation therapy. It is this resistance that prompted Yale researchers to develop a novel cell culture technique to isolate and study ACC cancer stem cells, known to be the root of tumor growth, aggressiveness, and resistance to chemotherapy and radiation, said co-senior author Sergey Ivanov, research scientist in surgery (otolaryngology). “Within ACC cells, we found the especially aggressive cancer stem cells. As important, we found the Achilles heel of these cells, which is their addiction to NOTCH1, a signaling molecule that helps these cells to survive therapy and multiply,” Ivanov said. “Fortunately, cancer stem cells can be killed by blocking NOTCH1 production.” The similarities between the ACC stem cells and [...]

Baseball and tobacco are a deadly mix

Source: www.bostonglobe.comAuthors: Dr. Howard Koh & Dr. Alan C. Woodward  Unhealthy as it looks: David Ortiz spat out his “chew” after flying out against Tampa Bay in Game 3 of the 2008 ALCS at Fenway Park.   Search the web for the phrase “tobacco and baseball” and you’ll find an association that dates back almost to the beginning of the sport. In the late 1800s, tobacco companies debuted baseball cards in cigarette packs. By the early 1900s, Bull Durham was advertising its chewing tobacco product on outfield fences. Today, cigarette smoking is prohibited or restricted in all Major League parks. Still, players, coaches, and others use smokeless tobacco, often referred to as “chew” or “dip,” in virtually every stadium across the country. But tobacco that is “smokeless” is not “harmless.” It contains at least 28 carcinogens and causes oral, pancreatic, and esophageal cancer, along with serious health problems such as heart disease, gum disease, tooth decay, and mouth lesions. The longstanding link between tobacco and baseball has led to tragic outcomes, for players and young fans alike. Baseball legend Babe Ruth died at age 53 of throat cancer after decades of dipping and chewing. Last summer, former Red Sox pitching great Curt Schilling announced that he had been treated for oral cancer, which he attributed to three decades of chewing tobacco. Sadly, his news came shortly after the death of Hall of Famer Tony Gwynn, at age 54, after a lengthy fight with salivary gland cancer. Gwynn, too, attributed his [...]

Smokeless tobacco ingrained in baseball, despite bans and Gwynn’s death

The use of smokeless tobacco is prevalent in the major leagues. (Kevork Djansezian / Getty Images)   Rick Vanderhook played for Cal State Fullerton's 1984 College World Series championship team and was a Titans assistant when they won two more. So he remembers the days when cans and pouches of smokeless tobacco were omnipresent in the uniform pockets of the participants. Not anymore. The NCAA banned tobacco use on the field in the early 1990s. "It's probably cut back, I'll say, almost 90% compared to what it was 25 years ago," said Vanderhook, who in his fourth season as head coach has guided the Titans back to Omaha, where they will open against defending national champion Vanderbilt on Sunday at 5 p.m. Smokeless tobacco remains ingrained in baseball culture, however, including the college and high school levels where it is banned. "It sounds bad, but it's part of the game," said Fullerton pitcher Thomas Eshelman, echoing nearly every coach and player interviewed for this article. Minor league players can be fined for having tobacco products in their locker or partaking on the field. Major leaguers are prohibited from using tobacco during televised interviews and player appearances, and they cannot carry tobacco products in their uniforms. But they are otherwise not prohibited from using it on the field. Before he died [...]

Study: Oral cancers take financial toll

Source: Dr.Biscuspid.com April 26, 2012 -- The cost of treating individuals with oral, orapharyngeal, and salivary gland cancers is significant, particularly for patients who undergo all three forms of treatment, according to a new study by Delta Dental of Michigan's Research and Data Institute. And for many that is only the beginning of the financial impact of the disease. The project, which involved Thomson Reuters, Delta Dental of Wisconsin, Vanderbilt University, and the University of Illinois at Chicago College of Dentistry, began in March 2010. It is the first retrospective data analysis of a large number of head and neck cancer patients in the U.S. analyzing direct and indirect costs and comparing those costs to a matched comparison group, according to the authors (Head Neck Onc, April 26, 2012). Using data from the 2004-2008 Thomson Reuters MarketScan Databases: Commercial Claims and Encounters Database, Medicare Supplemental and Coordination of Benefits Database, Medicaid Multi-State Database, and the Health Productivity and Management Database, the researchers retrospectively analyzed claims data of 6,812 OC/OP/SG patients with employer-sponsored health insurance, Medicare, or Medicaid benefits. They found that, on average, total annual healthcare spending during the year following diagnosis was $79,151, compared with $7,419 in a group comprising similar patients without these cancers. They also found that the average cost of care almost doubled when patients received all three types of treatment: surgery, radiation, and chemotherapy. Healthcare costs were higher for oral cancer patients with commercial insurance ($71,732, n = 3,918), Medicare ($35,890, n = 2,303), and [...]

Researchers ID virus that causes salivary gland cancer

Source: DrBicuspid.com Cytomegalovirus (CMV) has been confirmed as a cause of the most common salivary gland cancers (Experimental and Molecular Pathology, November 10, 2011). CMV joins a group of fewer than 10 identified oncoviruses -- cancer-causing viruses -- including HPV. The findings are the latest in a series of studies by researchers from the Laboratory for Developmental Genetics at the University of Southern California (USC) that together demonstrate CMV's role as an oncovirus, a virus that can either trigger cancer in healthy cells or exploit mutant cell weaknesses to enhance tumor formation. The conclusion that CMV is an oncovirus came after rigorous study of both human salivary gland tumors and salivary glands of postnatal mice, according to lead author Michael Melnick, DDS, PhD, a professor of developmental genetics in the Ostrow School of Dentistry at USC and co-director of the developmental genetics lab. This study illustrates that the CMV in the tumors is active and also that the amount of virus-created proteins found is positively correlated with the severity of the cancer, Melnick said. After salivary glands obtained from newborn mice were exposed to purified CMV, cancer developed. In addition, efforts to stop the cancer's progression identified how the virus was acting upon the cells to spark the disease. The researchers also identified a specific molecular signaling pathway exploited by the virus to create tumors. With the new information about CMV's connection to cancer comes hope for new prevention and treatment methods, Dr. Melnick noted. This news story was resourced [...]
