The number of cancer survivors in the United States increased to 11.7 million in 2007, according to a report released by the Centers for Disease Control and Prevention (CDC) and the National Cancer Institute (NCI), part of the National Institutes of Health (NIH). Women survive more often, and survive longer, according to the report.
There were 3 million cancer survivors in 1971 and 9.8 million in 2001. Researchers attributed longer survival to a growing aging population, early detection, improved diagnostic methods, more effective treatment and improved clinical follow-up after treatment.
The study, “Cancer Survivors in the United States, 2007,” is published today in the CDC’s Morbidity and Mortality Weekly Report.
To determine the number of survivors, the authors analyzed the number of new cases and follow-up data from NCI’s Surveillance, Epidemiology and End Results Program between 1971 and 2007. Population data from the 2006 and 2007 Census were also included. The researchers estimated the number of persons ever diagnosed with cancer (other than non-melanoma skin cancer) who were alive on Jan. 1, 2007. Read more »

High rates of inappropriate antibiotic use continued despite a 15-year campaign by the Centers for Disease Control and Prevention (CDC) aimed at Michigan physicians and consumers on the dangers of antibiotic overuse.
The Center for Healthcare Research & Transformation (CHRT) released an issue brief detailing overall antibiotic prescribing for adult Blue Cross Blue Shield of Michigan (BCBSM) members. (The project is a non-profit partnership between the University of Michigan and BCBSM.)
While antibiotic prescribing in adults decreased 9.3 percent from 2007 to 2009, it increased 4.5 percent for children during the same time period. The studies found significant differences in prescribing patterns between rural southeast Michigan and the rest of the state, particularly for children. Children in rural southeastern Michigan were prescribed an average of .93 antibiotics per year, while elsewhere children were prescribed an average of 1.0 per year.
“The continuing high rate of antibiotic use for viral infections in children and adults — particularly outside of southeast Michigan — is of great concern, as is the increase in the use of broad spectrum antibiotics in children,” said Marianne Udow-Phillips, CHRT’s director. “Using antibiotics when they are unnecessary — or treating simple infections with drugs that should be reserved for the most serious infections — are practices that contribute to antibiotic resistance, making future infections harder to treat.”
Nearly half (49.1 percent) of antibiotic prescriptions in the study population were for broad spectrum antibiotics in 2009, compared to the national rate of 47 percent. Between 2007 and 2009, prescriptions for what the National Committee for Quality Assurance calls “antibiotics of concern” declined slightly in adults, decreasing 0.4 percent during that time period. In the same time period, antibiotics of concern prescribed to children increased 3.4 percent, from 44.9 percent to 46.4 percent.
One possible explanation for the rising rate in children is a rise in resistant pathogens in ear infections, according to the study brief. Other possible reasons are that kids get different infections than adults, and that some drugs that are used in adults are not used for pediatric patients. Read more »

A new study finds that half of men in America are infected with the HPV virus. Dr. Jon LaPook reports on the growing concern that the virus in men could be responsible for an increase in head and neck cancers.
HPV Affects Half Of U.S. Men
A study out [yesterday] in The Lancet by Moffitt Cancer Center researcher Anna Giuliano, Ph.D., and her colleagues finds that 50 percent of men ages 18 to 70 in Brazil, Mexico, and the U.S. have genital infection with human papillomavirus (HPV). HPV is the virus that causes cervical cancer in women. It also causes warts and cancer of the genitals and anus in both men and women. Over the past several years, researchers have realized that the virus can also cause cancer of the head and neck.
Aimee R. Kreimer, Ph.D., of the National Cancer Institute, estimates that about 65 percent of the approximately 8,000 cancers of the tonsils and base of the tongue (oropharynx) seen in the U.S. in 2010 were from HPV infection; eighty percent of these are in men. The rates for HPV-associated cancers like these are increasing; for sites like the mouth and larynx that are associated with tobacco and alcohol use, the rates are decreasing (though still too high since too many people still smoke and abuse alcohol).
An infection rate of 50 percent for a virus that can cause cancer sounds scary. But knowing a few more facts about HPV helps put the risk in perspective. About 90 percent of men and women infected with HPV virus get rid of it on their own within about two years. There are many different strains of HPV — some that cause cancer and some that don’t. Only about 6 percent of men have genital infection with HPV 16 — the strain linked to more than 90 percent of cancers of the head and neck. And only about 0.6 percent of men have HPV 16 in specimens taken from their mouths; what percentage of those men go on to develop head and neck cancer is unknown. Read more »

Less than one in three primary care practices offer all 10 recommended adult vaccines, citing a variety of financial and logistical reasons.
Researchers sponsored by the Centers for Disease Control and Prevention sampled 993 family physicians and 997 general internists. Of the respondents, 27 percent (31 percent of family practitioners and 20 percent of internists) stocked all 10. Results appear in the Feb. 17 issue of the journal Vaccine.
The 10 vaccines were hepatitis A; hepatitis B; human papillomavirus vaccine (HPV); combined measles, mumps, and rubella (MMR); meningococcal conjugate vaccine (MCV4); pneumococcal polysaccharide (PPSV23); tetanus diphtheria (Td); combined tetanus, diphtheria, and pertussis (Tdap); varicella; and zoster.
Of the responding practices, two percent plan to stop vaccine purchases, 12 percent plan to increase them and the rest had no plans to change their vaccination stocking habits. But physicians who identified themselves as their respective practices’ decision makers for stocking vaccines were more likely to decrease the number of different vaccines stocked for adults (11 percent vs. three percent; P=.0001).
The National Vaccine Advisory Committee, a group that advises the various federal agencies involved in vaccines and immunizations, arrived at even bleaker figures in 2009, reported the April 2009 issue of ACP Internist. For example, 62 percent of decision makers in practices said they had delayed purchase of a vaccine at some time in the prior three years due to financial concerns. And in the prior year, 16 percent of practice decision makers had seriously considered stopping vaccinations for privately-insured patients due to the cost and reimbursement issues. Read more »

Enriched chicken feed may have resulted in eggs having less cholesterol and more Vitamin D than previously measured, reports the U.S. Department of Agriculture (USDA).
A large egg today has about 185 milligrams of cholesterol, down 14 percent from 215 milligrams in 2002, according to new research from the USDA’s Agricultural Research Service, reports USA Today. Also, an egg today has 41 international units (IUs) of Vitamin D, up 64 percent from 25 IUs measured in 2002. (That’s still only about 7 percent of the 600 IUs recommended per day.)
The agency regularly does nutrient checks on popular foods, this time analyzing eggs taken from store shelves in 12 locations around the country. The American Egg Board said in a press release that hen feed is made up mostly of corn, soybean meal, vitamins and minerals. Nutrition researchers at Iowa State University are also looking into reasons why cholesterol in eggs is decreasing.
The government’s “Dietary Guidelines for Americans” recommend that most people eat less than 300 milligrams of total dietary cholesterol a day, and people at a high risk of cardiovascular disease should eat less than 200 milligrams a day. The average American man consumes about 337 milligrams of cholesterol a day and the average woman consumes 217 milligrams, reports the Los Angeles Times.
One egg a day fits within the average, healthy American’s diet, reports WebMD, citing research funded by the Centers for Disease Control and Prevention and by the American Egg Board — owners of the slogan “the incredible, edible egg.”
