Why groundbreaking new cancer drugs still don’t work for most patients

Immunotherapy, which aims to harness the body’s immune system to fight off certain cancers, has received plenty of attention, praise and investment in recent years. Breakthrough treatments for melanoma and other cancers have shown startling results, giving some patients months and often years of life they almost certainly would not otherwise have had.

Yet, for all their promise, immune therapies have not produced such dramatic results for the majority of patients. The same drug that causes metastatic melanoma to vanish in one patient might have no effect on another. At best, only one or two patients out of five will respond to immunotherapy treatments — remarkable numbers compared to past standards, but still far lower than anyone would like.

New research published Monday in the journal Nature explores the molecular mechanisms that prevent immunotherapy drugs from working in some patients, and researchers hope the findings will help make the treatments more effective over time.

In short, the researchers studied why certain tumors were able to evade immune therapies designed to unleash the body’s defenses to fight cancer. They noted that tumors with a high concentration of “T cells,” a type of white blood cell essential to the human immune system, were more responsive to the treatments. Tumors with a low number of T cells inside what researchers call the “cancer microenvironment” were far less responsive to the new drugs.

“The tumors are acting to protect themselves,” said Weiping Zou, a senior author of the study and a professor of surgery, immunology and biology at the University of Michigan’s medical school. “If the T cells cannot get in, they have no way to kill the tumors.”

Using human and mouse models of ovarian cancer cells, he and other scientists experimented with specific drugs aimed at helping generate more T cells within a tumor, so that it would then be more responsive to immunotherapy. Although it’s early, the approach seems to have promise.

Immune therapies have rapidly become a pillar of cancer treatment in recent years, and numerous trials are underway in hopes of expanding the successes to bladder cancer, breast cancer, Hodgkin’s lymphoma, head and neck tumors, and other types of the disease. Researchers also are testing the new drugs in combination with one another and with other therapies.

The main obstacle has been the realization that some cancers have proved less susceptible to immune therapies, and some patients have fared far better than others. If researchers such as Zou and his colleagues can engineer ways to make game-changing immune therapies effective in more patients, that would be a game-changing feat.

“How can we make the responders more responsive, and make the non-responders become responders?” Zou said. “That’s the whole goal.”

Researchers Find Hookah Smoking Can Lead to Serious Oral Conditions – Equivalent To Smoking 100 Cigarettes

CHICAGO, Oct. 28, 2015 /PRNewswire/ — According to the Centers for Disease Control and Prevention, 2.3 million Americans smoke tobacco from pipes, and many of those who smoke waterpipes, or hookahs, believe it’s less harmful than cigarettes. However, research published in The Journal of the American Dental Association (JADA) suggests hookah smoking is associated with serious oral conditions including gum diseases and cancer.

“We found that waterpipe smoking is associated with serious health problems affecting the head and neck region,” said study author Teja Munshi, B.D.S., M.P.H of Rutgers University. “The public needs to know they are putting themselves at risk. They should be made aware of the dangers of smoking hookahs.”

The authors conducted a literature review that focused on waterpipe smoking and head and neck conditions. They found waterpipe smoking to be associated with gum diseases, dry socket, oral cancer and esophageal cancer among other conditions. According to the World Health Organization, smoking a hookah is the equivalent of smoking 100 cigarettes, based on the duration and number of puffs in a smoking session.

“This study sheds light on the common misconception that smoking from a waterpipe is somehow safer than smoking a cigarette,” said JADA Editor Michael Glick, D.M.D. “Whether you are smoking a cigarette, an e-cigarette, a cigar, or tobacco from a waterpipe, smoking is dangerous not only to your oral health but to your overall health.”

The American Cancer Society is hosting The Great American Smokeout on November 19, 2015, an annual event that encourages smokers of all kinds to give up the habit. The event asks smokers to quit even for just one day to take a step toward a healthier life.

Millions of Americans still use traditional methods of smoking, but emerging trends in the smoking industry, such as hookah smoking and e-cigarettes pose dangers as well. E-cigarettes are devices that turn liquid into a vapor containing nicotine. In an editorial in the September 2015 issue of JADA, authors warned readers of the potential dangers of e-cigarettes, indicating that oral health effects of their use has been inadequately investigated.

“Additional research is needed on the impact smoking has on overall health, but it’s clear that smoking of all kinds has the potential to be dangerous,” said Dr. Glick.

Dentists have an important role in advising patients of the dangers of smoking. The American Dental Association has long been a proponent of educating the public about its hazards and has urged for continued research into the adverse health effects of tobacco use.

Manitoba expands HPV vaccination program to include boys

Human-papillomavirus-HPV-va

While most HPV infections go away over time with no treatment, a few can go on to cause cancer.

Health Minister Sharon Blady said the province’s vaccine program will be expanded next year to include Grade 6 and Grade 9 boys as part of Manitoba’s cancer strategy.

The province will also be doing a catch-up period in grade 9. About 59 percent of the physicians recommended HPV vaccination more often for adolescents who they perceived to be at higher risk for getting an HPV infection, as opposed to recommending it routinely for all adolescents.

“Human papillomavirus can cause abnormal cell changes that can lead to cervical cancer, as well as cancer of the vagina, vulva, penis, anus, mouth and throat”, said Dr. Sri Navaratnam, president and CEO, CancerCare Manitoba.

A study in Texas found that a more rigorous, information driven outreach program increased the number of children receiving the vaccine, and other recent studies have reinforced the efficacy of the vaccine to prevent cancer and not promote promiscuity among teenagers.

Any girl or boy who misses the vaccine in Grade 6 will be eligible to get it in later years free of charge under the province’s “once eligible, always eligible”, program. But now we know it causes cancer in men as well.

Gilkey and colleagues found that 27 percent of physicians across the country reported that they do not strongly endorse HPV vaccination, and 26 percent and 39 percent reported that they do not provide timely recommendations for vaccinating girls and boys, respectively.

“The vaccine’s definitely most effective when you’re younger because you have A better immune response to vaccines and when you haven’t been exposed to the virus yet”, he said.

Routledge also said parents will need to give consent for their kids to receive the shot.

Saskatchewan Health Minister Dustin Duncan says offering the HPV vaccine for free to boys is something the province is looking at. “Vaccinating boys with the HPV vaccine will help prevent transmission of the virus and help reduce the incidence and mortality of all HPV-related cancers”. Nova Scotia has announced it plans to do the same.

Less Is More for HPV Oropharyngeal Cancer Reduced-intensity regimen clears disease in 86% of cases

Source: www.medpagetoday.com
Author: Charles Bankhead
 

SAN ANTONIO — Less intense treatment of low-risk human papillomavirus (HPV)-related oropharyngeal cancer achieved a high rate of pathologic complete response (pCR) and favorable patient-reported outcomes, a preliminary trial showed.

Overall, 37 of 43 (86%) patients achieved pCR with deintensified chemoradiation, including all but one evaluable primary tumor. The pCR rate was virtually identical to historical rates achieved with standard regimens, according to Bhishamjit Chera, MD, of the University of North Carolina (UNC) at Chapel Hill, and colleagues.

Selected patient-reported adverse events peaked during the first 6 to 8 weeks and then declined thereafter. About 40% of patients required feeding tubes for a median duration of 15 weeks, but no patients required permanent feeding tubes, they reported here at the American Society for Radiation Oncology meeting.

The regimen consists of lower doses of radiotherapy and concurrent cisplatin, administered over 6 weeks. With high-dose therapy, the radiation protocol requires an additional week.

“Though we have limited follow-up, the pathological complete response rate with this reduced-intensity chemoradiotherapy regimen is very high in patients with favorable-risk oropharyngeal squamous-cell carcinoma,” Chera said. “The early quality-of-life measurements are encouraging, particularly the data on swallowing. We are optimistic that these results with reduced-intensity treatment will translate into good long-term disease control with less toxicity.”

The study reflects the current trend and momentum in the management of HPV-positive oropharyngeal cancer, said Zain Husain, MD, of Yale Cancer Center in New Haven, Conn.

“This is the second study to show that de-escalation of therapy might work, and so far, the results really look good,” Husain told MedPage Today. “This is a really important issue, and all of our trials are moving in that direction.”

NRG Oncology (formerly RTOG) has already launched a trial using the UNC regimen, “which gives us a lot of confidence that this is a good regimen,” Husain added. Nonetheless, reduced-intensity treatment remains investigational and should not be used in clinical practice. Randomized clinical trials with adequate follow-up will be required to determine the ultimate role of less intense therapy for HPV-positive oropharyngeal cancer, he said.

Background

HPV-positive oropharyngeal cancer accounts for 60% to 70% of new cases of oropharyngeal cancer in the U.S., and the incidence has continued to rise. In general, HPV-positive disease has a more favorable prognosis as compared with HPV-negative oropharyngeal cancer.

At many institutions, standard therapy for newly diagnosed HPV-positive oropharyngeal cancer consists of total-dose radiotherapy of 70 Gy administered over 7 weeks, and concurrent cisplatin 100 mg/m2 for 3 weeks. The regimen achieves a high rate of pCR but causes substantial toxicity. Given the overall favorable prognosis of HPV-positive oropharyngeal cancer, many specialists have begun to ask whether reduced-intensity treatment might be just as effective with less toxicity.

Chera reported findings from a prospective phase II trial of reduced-intensity chemoradiation for low-risk HPV-positive oropharyngeal cancer. Eligible patients had diagnoses of T0-3, N0-2c, M0 disease associated with minimal or negative smoking history. Treatment consisted of a total radiation dose of 60 Gy administered in 2-Gy fractions daily for 6 weeks, plus concurrent weekly cisplatin 30 mg/m2. The regimen represented a 10-Gy reduction in the usual radiation dose and a 40% reduction in the usual chemotherapy dose, Chera said.

The primary outcome was pCR and was based on experience with usual high-dose therapy, which has been associated with a pCR rate of 87%. Patients undergo biopsy of the primary site 6 to 14 weeks after completing chemoradiation, as well as resection of any initially-positive lymph nodes. Secondary endpoints included toxicity, quality of life (QOL), and clinical outcomes of treatment.

Key Findings

The 86% pCR rate compared favorably with the 87% rate demonstrated by historical data. The overall results included pCR in 40 of 41 evaluable primary tumors (two of which were stage T0 at baseline) and pCR in the neck in 33 of 39 patients (four of whom had N0 status at baseline).

After a median follow-up of 21 months, all 43 patients remain alive and without evidence of disease, including 38 patients who have at least 1 year of follow-up.

Investigators evaluated QOL by means of an instrument developed by the European Organization for Research and Treatment of Cancer (EORTC QLQ H&N-35). Focusing on common adverse effects of chemoradiation for head and neck cancer, Chera noted that the severity score for dry mouth, sticky saliva, and swallowing all increased during the first 6 to 8 weeks, particularly dry mouth and sticky saliva.

The score for dry mouth peaked at about 70 on the 100-point scale and the score for sticky saliva rose to a maximum of about 60. Score for dry mouth remained at about 60 at 12 months, whereas the saliva score declined to about 40. The effect on swallowing was less severe, reaching a maximum of about 20 and then declining to less than 10 at 12 months.

Patient-reported symptoms exhibited a similar pattern as the dry mouth score averaged less than 0.5 (0 to 4 scale) at baseline, increasing to almost 2.5 at 6 to 8 weeks, and then declining to less than 2.0 by 1 year. Patient-rated swallowing difficulty was less than 0.5 at baseline, about 1.0 at 6 to 8 weeks, and slightly less than 1.0 at 1 year.

Physician-rated grade 3/4 toxicity and patient-rated severe/very severe toxicity included mucositis (34%/45%), pain (5%/48%), nausea (18%/52%), vomiting (5%/34%), dysphagia (39%/55%), and xerostomia (2%/75%).

Chera and colleagues have already closed enrollment for another phase II trial that will evaluate a reduced-intensity regimen that makes surgery optional, omits chemotherapy for patients with T1-2 N0-1 disease, and includes patients with as much as a 30 pack-year smoking history but who have a 5-year period of abstinence.

A planned “third-generation” phase II trial will evaluate the feasibility of cancer genetics risk-based stratification of patients and examine more specifically the question of whether reduced-intensity treatment is possible for patients with a >10 pack-year smoking history.

Athletes drive increase in high schoolers’ use of smokless tobacco, CDC study shows

Author: www.kyforward.com web staff

Sept.-2015-100-percent-smoke-free-schools

High-school athletes are using more smokeless tobacco, even though overall tobacco use among high-school students has declined, according to a study published by the federal Centers for Disease Control and Prevention.

We can do more to protect America’s youth from a lifetime of addiction,” Tom Frieden, CDC director, said in a press release. “The fact is, smokeless tobacco products, such as chewing tobacco, snuff or dip, can cause cancer of the mouth, esophagus and pancreas. And the nicotine in these products is harmful to the developing brain. Because we know tobacco-free policies in schools and other public recreational areas work, we must take action now so that our children are safe from these toxins.”

Student responses to the national Youth Risk Behavior Survey from 2001 through 2013 show that the share reporting any tobacco use dropped to 22.4 percent from 33.9 percent, and the rate of those smoking combustible tobacco products dropped to 19.5 percent from 31.5 percent. However, those who reported using smokeless tobacco products increased to 8.8 percent from 8.2 percent.

The increased use of smokeless tobacco was driven by athletes. The rate among non-athletes remained unchanged at 5.9 percent but has “increased significantly” to 11.1 percent from 10 percent in youth athletes.

Researchers suggest that athletes are aware of the adverse consequences of smoking on athletic performance, but may view smokeless tobacco as “less harmful, socially acceptable, or even a way to enhance athletic performance.”

The 2013 YRBS found that 26.3 percent of Kentucky’s high school youth reported any use of tobacco; 17.9 percent were smoking cigarettes, and 13.2 percent reported using smokeless tobacco.

“Tobacco use among youth athletes is of particular concern because most adult tobacco users first try tobacco before age 18,” Brian King, deputy director for research translation in the CDC Office on Smoking and Health, said in a press release. “The younger people are when they start using tobacco, the more likely they are to become addicted and the more heavily addicted they can become.”

The reports calls for increased education about the dangers of smokeless tobacco; recognition that the tobacco industry pushes smokeless tobacco as an alternative to smoking where it is prohibited; that the role of professional athletes, many who use smokeless tobacco, must be part of the discussion because they are often considered role models by youth; and that “implementing and enforcing tobacco-free policies that prohibit all tobacco use on school campuses and at all public recreational facilities, including stadiums, parks, and school gymnasiums, by players, coaches, referees, and fans might help reduce tobacco use among student athletes.”

As of September, Kentucky had 47 school districts with comprehensive tobacco free policies. These policies cover 45 percent of Kentucky’s students and represents 27 percent of the school districts in the state, according to the Kentucky 100% Tobacco Free Schools website.

“Creating 100 percent tobacco-free environments is one of the best ways we can set our kids up for a healthy future,” U.S. Surgeon General Vivek H. Murthy said in the release. “It helps them see that being tobacco-free is the way to better health and a longer life.”

Multisite HPV16/18 Vaccine Efficacy Against Cervical, Anal, and Oral HPV Infection

Source: www.oxfordjournal.com
Authors: Daniel Bleacher, Aimee Kreimer, Mark Schiffman, Rolando Herrero, Ana Cecilia Rodriguez, Douglas Lowy, Carolina Porras, John Schiller, Wim Quint, Silvia Jiminez, Mahboobeh Safaeian, Linda Struijk, John Scchussler, Allan Hildesheim, Paula Gonzalez

 

Background: Previous Costa Rica Vaccine Trial (CVT) reports separately demonstrated vaccine efficacy against HPV16 and HPV18 (HPV16/18) infections at the cervical, anal, and oral regions; however, the combined overall multisite efficacy (protection at all three sites) and vaccine efficacy among women infected with HPV16 or HPV18 prior to vaccination are less known.

Methods: Women age 18 to 25 years from the CVT were randomly assigned to the HPV16/18 vaccine (Cervarix) or a hepatitis A vaccine. Cervical, oral, and anal specimens were collected at the four-year follow-up visit from 4186 women. Multisite and single-site vaccine efficacies (VEs) and 95% confidence intervals (CIs) were computed for one-time detection of point prevalent HPV16/18 in the cervical, anal, and oral regions four years after vaccination. All statistical tests were two-sided.

Results: The multisite woman-level vaccine efficacy was highest among “naïve” women (HPV16/18 seronegative and cervical HPV high-risk DNA negative at vaccination) (vaccine efficacy = 83.5%, 95% CI = 72.1% to 90.8%). Multisite woman-level vaccine efficacy was also demonstrated among women with evidence of a pre-enrollment HPV16 or HPV18 infection (seropositive for HPV16 and/or HPV18 but cervical HPV16/18 DNA negative at vaccination) (vaccine efficacy = 57.8%, 95% CI = 34.4% to 73.4%), but not in those with cervical HPV16 and/or HPV18 DNA at vaccination (anal/oral HPV16/18 VE = 25.3%, 95% CI = -40.4% to 61.1%). Concordant HPV16/18 infections at two or three sites were also less common in HPV16/18-infected women in the HPV vaccine vs control arm (7.4% vs 30.4%, P < .001).

Conclusions: This study found high multisite vaccine efficacy among “naïve” women and also suggests the vaccine may provide protection against HPV16/18 infections at one or more anatomic sites among some women infected with these types prior to HPV16/18 vaccination.

Alternative Tobacco Products as a Second Front in the War on Tobacco

Associations Between Initial Water Pipe Tobacco Smoking and Snus Use and Subsequent Cigarette Smoking: Results From a Longitudinal Study of US Adolescents and Young Adults

Importance Many adolescents and young adults use alternative tobacco products, such as water pipes and snus, instead of cigarettes.

Objective To assess whether prior water pipe tobacco smoking and snus use among never smokers are risk factors for subsequent cigarette smoking.

Design, Setting, and Participants We conducted a 2-wave national longitudinal study in the United States among 2541 individuals aged 15 to 23 years old. At baseline (October 25, 2010, through June 11, 2011), we ascertained whether respondents had smoked cigarettes, smoked water pipe tobacco, or used snus. At the 2-year follow-up (October 27, 2012, through March 31, 2013), we determined whether baseline non–cigarette smokers had subsequently tried cigarette smoking, were current (past 30 days) cigarette smokers, or were high-intensity cigarette smokers. We fit multivariable logistic regression models among baseline non–cigarette smokers to assess whether baseline water pipe tobacco smoking and baseline snus use were associated with subsequent cigarette smoking initiation and current cigarette smoking, accounting for established sociodemographic and behavioral risk factors. We fit similarly specified multivariable ordinal logistic regression models to assess whether baseline water pipe tobacco smoking and baseline snus use were associated with high-intensity cigarette smoking at follow-up.

Exposures Water pipe tobacco smoking and the use of snus at baseline.

Main Outcomes and Measures Among baseline non–cigarette smokers, cigarette smoking initiation, current (past 30 days) cigarette smoking at follow-up, and the intensity of cigarette smoking at follow-up.

Results Among 1596 respondents, 1048 had never smoked cigarettes at baseline, of whom 71 had smoked water pipe tobacco and 20 had used snus at baseline. At follow-up, accounting for behavioral and sociodemographic risk factors, baseline water pipe tobacco smoking and snus use were independently associated with cigarette smoking initiation (adjusted odds ratios: 2.56; 95% CI, 1.46-4.47 and 3.73; 95% CI, 1.43-9.76, respectively), current cigarette smoking (adjusted odds ratios: 2.48; 95% CI, 1.01-6.06 and 6.19; 95% CI, 1.86-20.56, respectively), and higher intensity of cigarette smoking (adjusted proportional odds ratios: 2.55; 95% CI, 1.48-4.38 and 4.45; 95% CI, 1.75-11.27, respectively).

Conclusions and Relevance Water pipe tobacco smoking and the use of snus independently predicted the onset of cigarette smoking and current cigarette smoking at follow-up. Comprehensive Food and Drug Administration regulation of these tobacco products may limit their appeal to youth and curb the onset of cigarette smoking.

Throat and tongue cancers linked to sexually transmitted virus on the rise

Source: www.theage.com.au
Author: Julia Medew

The sexual revolution is producing a new wave of throat and tongue cancers among middle-aged people, who are falling victim to a rare side effect of the “common cold of sexually transmitted infections”.

A growing number of Australians with oropharyngeal cancer are testing positive to the human papillomavirus (HPV), suggesting it has caused their disease rather than smoking or heavy drinking – factors responsible for many head and neck cancers in the past. Oropharyngeal cancer is usually found in the back third of the tongue or the tonsils. In 2014, about 125 Victorians were diagnosed with it. Most were men.

An Australian study of 515 patients diagnosed with the condition between 1987 and 2010 found that the proportion of people with an HPV-related diagnosis increased from 20 per cent between 1987 and 1995 to 64 per cent between 2006 and 2010. Over the same period, the proportion of people diagnosed with throat cancer who had never smoked increased from 19 per cent to 34 per cent, suggesting HPV may overtake smoking and drinking as a cause of the cancer in future.

American doctors say more oral sex following the sexual revolution of the 1960s probably spread HPV to more people’s mouths and throats. Actor Michael Douglas said he believed oral sex was to blame for his HPV-related throat cancer in 2013. But Dr Matthew Magarey​, an ear nose and throat surgeon at Epworth and Peter MacCallum hospitals in Melbourne, said while HPV-related throat cancers were occurring in more people aged 40 to 60, it should not necessarily be associated with oral sex because scientists believe HPV may be transmitted through kissing or simple hand to mouth contact as well.

Up to 80 per cent of the adult population is thought to have had some sort of HPV infection during their life (there are more than 100 strains) and most of them will not have experience any symptoms. Many people clear the virus within months of getting it.

Dr Magarey said a tiny proportion of people will get an HPV-related cancer, such as cervical, anal, or throat cancer. He said HPV in the throat probably took 30 to 40 years to turn into a cancer in the minority of people it affects in that way. He said treatments were getting better for the cancer, which has a high survival rate if found early. Depending on the circumstances of the cancer, radiation, chemotherapy and sometimes surgery are used to treat it. While the surgery has been long and complicated in the past, Dr Magarey said a new robotic procedure available at Peter Mac and Epworth was helping surgeons remove cancers more precisely and in less time. This was reducing long-term recovery problems such as difficulty eating and drinking and swallowing.

Dr Magarey said the most common first sign of throat cancer was a lump in the neck that persists for more than two or three weeks. Symptoms can also include a sore throat that persists for more than three weeks and difficulty swallowing.

“If you have these symptoms, see your GP and get a referral to a qualified ENT surgeon who can properly examine the throat. Just looking in the mouth is not enough,” he said.

Dr Marcus Chen, a sexual health specialist with Alfred Health, said the Australian government’s HPV Gardasil vaccination program for young people will reduce such cancers in future. In the meantime, he said testing for HPV – the “common cold of sexually transmitted infections” – was not recommended because there is no way of treating the virus or preventing it from being passed on to others.

California to big-league ballplayers: Stop chewing tobacco

Source: apnews.myway.com
Author: John Rogers

California lawmakers have taken the first step toward accomplishing something Major League Baseball could never do: Stop players from stuffing those big wads of chewing tobacco into their mouths during games. With Gov. Jerry Brown signing a bill earlier this week banning the use of smokeless tobacco in all California ballparks, a practice dating to the days of Babe Ruth and Ty Cobb now seems headed toward the sport’s endangered species list.

Although California is only one state, it is home to five of Major League Baseball’s 30 teams, and team owners themselves have been pressing for a ban for years. Last May they got one in San Francisco, home of the reigning World Series champion Giants. In August they got another in Boston, site of fabled Fenway Park, and when Brown signed Assembly Bill 768 on Sunday one was already in the works for Los Angeles.

“Major League Baseball has long supported a ban of smokeless tobacco at the Major League level and the Los Angeles Dodgers fully support the Los Angeles City Tobacco ordinance and Campaign for Tobacco-Free Kids,” the Dodgers said in a statement last month.

Major League Baseball still needs buy-in from the players, however, because the statewide ban that takes effect before next season has no provision for enforcement.

“The question we’ve been asked is are we going to have police officers walking around checking lips, and no, that’s not the case,” said Opio Dupree, chief of staff to Assemblyman Tony Thurmond, D-Richmond, who introduced the bill. “It’s going to be left to the team and the league.”

Interviews with players in recent years indicate that many are ready to quit — if they could.

“I grew up with it,” pitcher Jake Peavy told the Boston Globe last year when the newspaper polled 58 players the Boston Red Sox had invited to spring training and found 21 were users.

“It was big with my family,” said Peavy who is now with the San Francisco Giants. “Next thing you know, you’re buying cans and you’re addicted to nicotine.”

He added he would like to quit to set a better example for his sons.

Last year’s World Series MVP, San Francisco Giant’s pitching ace Madison Bumgarner, also chews tobacco but told The Associated Press earlier this year he planned to quit after San Francisco became the first city in the nation to adopt a ban. That one, like the statewide provision, also takes effect next year.

“I’ll be all right. I can quit,” Bumgarner said in August. “I quit every once in a while for a little while to make sure I can do it.”

All the players should, said Christian Zwicky, a former Southern California Babe Ruth League most valuable player who grew up watching the Los Angeles Dodgers play and says he never cared for seeing all that tobacco chewing and the spitting of tobacco juice that follows.

It didn’t influence him to take up the practice, the 22-year-old college student says, but he can see how it might have affected others.

“I understand the sentiment there,” said Zwicky who adds he’s not a big fan of government regulation but supports this law. “You don’t want these people that kids look up to using these products that could influence children in a negative way.”

Moves to adopt a comprehensive ban have been gaining support in recent years, fueled by such things as last year’s death of popular Hall of Famer Tony Gwynn of the San Diego Padres, who blamed his fatal mouth cancer on years of chewing tobacco. Former pitcher Curt Schilling, a cancer survivor, has also taken up the cause.

Use of smokeless tobacco has been banned in the minor leagues for more than 20 years, but Major League Baseball and its players union haven’t been able to reach agreement on a similar restriction. Players and coaches are prohibited from chewing tobacco during television interviews and can’t been seen carrying tobacco products when fans are in the ballparks. But the chewing during the game continues.

“It’s a tough deal for some of these players who have grown up playing with it and there are so many triggers in the game,” San Francisco Giants manager Bruce Bochy told the AP earlier this year.

“I certainly don’t endorse it,” said Bochy, an on-and-off-again user for decades. “With my two sons, the one thing I asked them is don’t ever start dipping.”

SA Developed Melanoma Drug Now Seen Effective in Fighting Lung Cancer

Source: www.woai.com
Author: News Radio 1200 WOAI Staff

 

1229_1264794779Keytruda, 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 cancer.

That means the treatment takes place without chemotherapy.

“Thus avoiding some of the toxicities associated with chemotherapy including hair loss, fatigue, a drop in counts, nausea and vomiting, and the spectrum of negative side effects you get with chemo.”

“Keytruda is showing activity in about ten or more other cancers, including liver cancer, head and neck cancer, and in a rare form of breast cancer.”

The FDA granted Keytruda ‘breakthrough therapy designation’ because of demonstrated preliminary clinical evidence that the drug may ‘offer a substantial improvement over available therapies.’
