Smoking, cancer, heart disease, and the oral-systemic link: Where we are with research

Source: www.dentistryiq.com Author: Richard H. Nagelberg, DDS Dr. Richard Nagelberg examines the links between smoking, lung cancer, and heart disease, as well as the types of research and studies that established the strength of their credibility over time. Likewise, he considers where we are today with the link between oral health and overall health as he evaluates the current state of oral-systemic research. Perhaps the most universally accepted facts in health care are the detrimental effects of tobacco, particularly cigarette smoking, for nearly every part of the body. It is safe to say that no one disputes the direct causal links between cigarette smoking, lung cancer, and heart disease. Listed below are only two statements regarding the state of this knowledge. ✔️The scientific evidence is incontrovertible: inhaling tobacco smoke, particularly from cigarettes, is deadly. Since the first Surgeon General’s Report in 1964, evidence has linked smoking to diseases of nearly all organs of the body. (surgeongeneral.gov. June 21, 2018) ✔️Smoking is by far the biggest preventable cause of cancer. Thanks to years of research, the links between smoking and cancer are now very clear. Smoking accounts for more than 1 in 4 UK cancer deaths, and 3 in 20 cancer cases. (cancerresearchuk.org) There is a boatload of research supporting this link. However, there has never been one large-scale double-blinded interventional study demonstrating that smoking causes lung cancer and heart disease. The fact that this link exists is based on the cumulative results of numerous smaller studies over a long period [...]

We Now Know Exactly How Many DNA Mutations Smoking Causes

Every 50 cigarettes you smoke gives you one extra DNA mutation per lung cell. Source: The Verge Author: James Vincent A common tactic for people trying to give up smoking is to quantify exactly how much damage — financial or physical — each cigarette or pack of cigarette does. How much does smoking cost you per month, for example, or how much shorter is your life going to be for each drag you take? Well, a new study into the dangers of smoking now lets us measure this damage right down to the number of mutations in your DNA. A research team led by scientists from Los Alamos National Laboratory compared tissue samples from 1,063 non-smokers and 2,490 smokers, examining each individual's DNA to look for mutations. They found that for every 50 cigarettes smoked, there is one extra DNA mutation for each cell in the lungs. Over the course of a year, this means that someone who smokes a pack a day (20 cigarettes) has 150 extra mutations per cell in the lung, 97 per larynx cell, 23 per mouth cell, 18 per bladder cell, and six per liver cell. These changes to the cells aren’t dangerous in themselves, but each one has the potential to turn into a cancerous growth. "Smoking is like playing Russian roulette: the more you play, the higher the chance the mutations will hit the right genes and you will develop cancer," Ludmil Alexandrov, the co-lead author of the study, told the New Scientist.

Depressed Head and Neck Cancer Patients Have Lower Survival and Higher Recurrence Risk

Source: www.OncologyNurseAdvisor.comAuthor: Kathy Boltz, PhD Depression is a significant predictor of 5-year survival and recurrence in patients with head and neck cancer, according to a new study published in Pyschosomatic Medicine (doi: 10.1097/PSY.0000000000000256). These findings represent one of the largest studies to report on the impact of depression on cancer survival. Although depression can have obvious detrimental effects on a person's quality of life, its impact on cancer patients is more apparent, explained lead author Eileen Shinn, PhD, assistant professor of Behavioral Science at The University of Texas MD Anderson Cancer Center, in Houston. Increasing evidence shows modest associations between elevated symptoms of depression and greater risk for mortality among patients with lung, breast, ovarian, and kidney cancers. The research team sought to clarify the influence of depression on survival, focusing their analysis on a single cancer type. By limiting the sample set and adjusting for factors known to affect outcome, such as age, tumor size, and previous chemotherapy, they were able to uncover a more profound impact of depression. The researchers followed 130 patients at MD Anderson with newly diagnosed oropharyngeal squamous cell carcinoma (OSCC), a type of cancer in which the tumor originates at the back of the throat and base of the tongue. At the beginning of their radiation therapy, Patients completed a validated questionnaire at the beginning of their radiation therapy to identify symptoms of clinical depression. Researchers monitored the participants, all of whom completed treatment, until their last clinic visit or death, a median period of [...]

SA Developed Melanoma Drug Now Seen Effective in Fighting Lung Cancer

Source: www.woai.comAuthor: News Radio 1200 WOAI Staff Keytruda, a cancer drug developed largely at San Antonio's START Center, has already proven to be effective in treating advanced melanoma to the point that it is the major part of former President Jimmy Carter's treatment. Now, News Radio 1200 WOAI reports Keytruda has been given 'fast track' approval by the FDA for use in treating lung cancer, the leading cause of cancer deaths in the United States. Dr. Amita Patnaik, a researcher and oncologist at START who helped develop the drug, says the impact of Keytruda on lung cancer patients has been amazing. "Close to 40% of those patients will receive a response," she said. "And of those patients who receive a response, about 80% of those patients will have a long term response." The life saving potential of Keytruda in fighting non small cell lung tumors is obvious. An estimated 221,000 Americans are diagnosed with lung cancer each year, and 158,000 die of the disease annually. Dr. Patnaik says Keytruda is becoming the most successful of what are known as 'targeted therapies,' drugs which trigger the body to take action to fight the cancer. She says both melanoma and lung cancer work essentially the same way to undermine the body's defenses. "The commonality between melanoma and lung cancer is there is a supressive effect of the cancer on the immune system." She says Keytruda essentially overrides that supressive effect, prompting the body to restart its natural immune defenses and fight the [...]

Current tobacco reports show 50 years of progress

Source: the-scientist.comAuthor: Jef Akst In 1964, the U.S. Surgeon General released the first report on the effect that cigarettes and other forms of tobacco have on human health, presenting strong evidence of the link between smoking and lung cancer, among other adverse consequences. During the last 50 years, significant progress has been made in terms of understanding how smoking causes various diseases and how to treat them, and educational campaigns have contributed to a drop in smoking rates from 42 percent to 18 percent of US adults. Nevertheless, more than 480,000 Americans still die from tobacco-related diseases each year, and additional health consequences continue to be linked to smoking. “Between now and mid-century, nearly 18 million Americans will die preventable avoidable deaths if we don’t do something to alter that trajectory,” Mitchell Zeller, the director of the Center for Tobacco Products of the Food and Drug Administration (FDA), said during a press conference held today here at the American Association for Cancer Research (AACR) meeting in San Diego, California. To this end, the AACR released a compilation of peer-reviewed research and review articles, published across seven of its journals, covering basic scientific research on the molecular mechanisms of tobacco carcinogenesis, tools for the diagnosis of lung cancer and other tobacco-related diseases, and the impact of the original Surgeon General’s report on tobacco control. Ellen Gritz from the University of Texas MD Anderson Cancer Center helped put the new report together. “Together, these reports add to the broad reach of important tobacco-related [...]

Nearly 6 Percent Of Lung Cancer Tissue Samples From Non-Smokers Show Signs That HPV May Have Triggered The Tumors

Article Date: 12 Apr 2013 - 1:00 PDT Source: Medical News Today A common virus known to cause cervical and head and neck cancers may also trigger some cases of lung cancer, according to new research presented by Fox Chase Cancer Center at the AACR Annual Meeting 2013. Examining tissue samples from lung cancer patients, the researchers found that nearly 6% showed signs they may have been driven by a strain of human papillomavirus (HPV) known to cause cancer. If HPV indeed plays a role in lung cancer in some patients, the next step is to better understand those tumors so they can be treated more effectively. "The ultimate goal," says study author Ranee Mehra, MD, attending physician in medical oncology at Fox Chase, "is to determine if we can target our therapies to the specific characteristics of these tumors." Studies from Asia have shown that lung tumors are frequently infected with HPV. The pattern makes sense, explains Mehra - the lungs are located very near the head and neck, which are known to be at risk of tumors upon exposure to some strains of HPV. To investigate, she and her colleagues examined 36 tissue samples from people diagnosed with non-small cell lung cancer who had never smoked, part of the Fox Chase Cancer Center Biosample Repository. The reason they chose non-smokers, Mehra explains, is that smoking is a major cause of lung cancer - but in non-smokers, the explanation is often less obvious. The researchers found that 4 out [...]

HPV linked to certain lung cancers; is oral sex to blame?

Source: www.medicaldaily.com Author: Jonathan Weiss By now, it's a given that smoking causes lung cancer. The American Lung Association reports that 80 to 90 percent of all cases of lung cancer are smoking-related. The remaining 10 to 20 percent, though, has been more of a mystery — until now. A new line of research has implicated thye sexually transmitted infection human papillomavirus, or HPV, in lung cancers that were found in non-smokers. HPV is the leading cause of all cervical cancer cases in the world. It's a well-known disease that's gottena lot of press in recent years; an effective vaccine was recently developed that can prevent the viral infection and subsequent cervical cancer development. Whether or not the vaccine should be required for teenage girls has become a hot-button political issue. Adding fuel to the fire, a research team from the Fox Chase Cancer Center recently looked at tissue samples from lung cancer patients who had no history of smoking and saw that close to 6 percent showed evidence that they had been driven by HPV infection. Four out of 36 lung samples had signs of infection from two strains of HPV known to cause cancer. Looking more closely at the two samples infected by one strain of HPV, Dr. Ranee Mehra, MD, attending physician in medical oncology at Fox Chase and her team saw signs the virus had integrated into the tumor's DNA — which is even more suggestive that the infection had caused the tumor in the first [...]

$27 Million Verdict Against R.J. Reynolds for Cancer Victim

Source: JDsupra.com A Florida man was awarded $27 million in compensatory and punitive damages against tobacco company R.J. Reynolds last month after doctors told him that 44 years of smoking caused his lung cancer. Plaintiff had lung removed due to cigarette addiction Thousands of lawsuits pending against big tobacco companies First payouts by big tobacco expected to be made today Addictive Habits Emmon Smith, a minister in Mariana, Florida, started smoking when he was a 13-year-old boy in 1944. Despite numerous attempts to quit, he couldn’t kick the addictive habit until he was forced to in 1992 by a cancer diagnosis and subsequent removal of one of his lungs. Smith sued tobacco company R.J. Reynolds in 2008, and in March of this year a jury awarded him $10 million in compensatory damages and $20 million in punitive damages; however, they found the plaintiff 30 percent at fault so he will receive only $7 million of the compensatory award, for a total of $27 million. Smith’s suit was led by attorney Richard Diaz as well as a team of attorneys from Crabtree & Associates and Ratzan Law Group. The Smith case was just one of more than 8,000 lawsuits against tobacco companies stemming from a 1990s class action known as the Engle case. In 2000, a Florida jury awarded class members a stunning $145 billion in punitive damages, finding that cigarettes are dangerous, addictive, carcinogenic, and most importantly, that tobacco companies knew all this and lied about it. “They found that [...]

Declines in Smoking and Lung Cancer Mortality in the U.S.: 1975–2000

Source: Oxford Journals Although changing smoking behaviors have had a major impact on lung cancer mortality in the U.S., the numbers of lung cancer deaths averted are only a small fraction of deaths that could have been avoided had all smoking ceased following the 1964 Surgeon General’s Report. Further efforts to control tobacco use are needed to decrease the impact of the disease, according to a study published March 14 in the Journal of the National Cancer Institute. The restrictions on smoking in public places, escalations in cigarette taxes, reduced access to cigarettes, and an increased public awareness on the health issues related to smoking have all helped steadily decrease the number of smokers in the U.S. since the mid 1950’s; however, little measurable information exists in regards to the amount lung cancer deaths have diminished in association with the decline in smoking. In order to determine the effect that reduced tobacco smoking has had on lung cancer mortality in the U.S., Suresh H. Moolgavkar, M.D., Ph.D., of the Program in Biostatistics and Biomathematics at the Fred Hutchinson Cancer Research Center in Seattle, Washington and colleagues built independent models based on cohort, case-control, or registry data and adjusted to overall mortality to estimate the number of lung cancer deaths prevented between 1975–2000. The data were distinguished by sex and birth decade (1890–1970), and the prevalence of smoking and lung cancer deaths were considered based on actual tobacco control (ATC), historical changes in smoking rates, no tobacco control (NTC), predicted smoking [...]

The 795 Thousand and Ending a Century of Tobacco

Source: Oxford Journals Tonight, a grandfather will read his grandson a soothing bedtime story. Yesterday, a mother saw her son perform a brilliant violin solo. Tomorrow, a grandfather will see his granddaughter complete the first unassisted triple play in their community's t-ball league history. What do these vignettes have in common? They represent just three of the 795 851 people––the 795 thousand––whose premature deaths from lung cancer were averted in the United States through aggressive tobacco control policies and interventions between 1975 and 2000, as determined by a series of consortium-based sophisticated modeling techniques and reported by Moolgavkar et al. (1) in this issue of the Journal. Sometimes, we become inured to the sheer number of deaths caused by tobacco—for example, a predicted 1 billion tobacco-caused deaths this century, 100 million people killed by tobacco in the 20th century, 6 million deaths per year globally, 443 000 deaths per year in the United States, etc. But, despite these enormous, and even numbing, numbers, we need to remember that every one of these 1 billion, 100 million, 6 million, or 443 000, was a father, mother, brother, sister, son, or daughter who, if tobacco had not intervened, would have enjoyed, and shared, a longer, healthier, and more fulfilling life. How did this happen? How did we allow tobacco, over the past 100 years, to kill and cause disease with such abandon? And, more important, how have we begun to turn the tide against the tobacco tsunami and how can we continue to learn from [...]
