New study: adult stem cells used in breast cancer treatment

From Life News.

Excerpt:

Stanford doctors have shown that women with advanced breast cancer show greater survival when treated with aggressive chemotherapy and their own adult stem cells.

Their study looked at long-term results for women with advanced, stage-4 breast cancer, who were treated 12-14 years ago with high-dose chemotherapy and their own, purified adult stem cells, compared to women who received chemotherapy and unpurified blood stem cells.

While the numbers of patients in this long-term study are small, the results are striking. Five of the 22 women (23 percent) who received their purified adult stem cells are still alive, four of whom have no sign of disease. Only seven of the 74 women (9 percent) who received the untreated cells are still alive, with five of those seven having no sign of disease. Women who received their own purified adult stem cells had a median survival of 60 months, whereas those receiving unpurified stem cells had a median overall survival of 28 months.

Senior author Dr. Judith Shizuru said:

“Our study suggests that the high-dose therapy strategy can be modified to include the use of cancer-free purified blood stem cells to yield better overall outcomes in women with advanced breast cancer.”

The results were published online in the journal Biology of Blood and Marrow Transplantation.

Which health care system is better? Canada or the United States?

Story from the Hoover Institute at Stanford University.

The article compares (pre-Obamacare) American health care to health care in other places like Canada, the UK and Europe.

The full article. I almost never cite the full article, but this is a must read. Men, pay close attention to the differences in prostate cancer treatment rates in a for-profit system versus a single-payer system, where bureaucrats decide who gets treatment.

MEDICINE AND HEALTH:

Here’s a Second Opinion

By Scott W. Atlas

Ten reasons why America’s health care system is in better condition than you might suppose. By Scott W. Atlas.

Medical care in the United States is derided as miserable compared to health care systems in the rest of the developed world. Economists, government officials, insurers, and academics beat the drum for a far larger government role in health care. Much of the public assumes that their arguments are sound because the calls for change are so ubiquitous and the topic so complex. Before we turn to government as the solution, however, we should consider some unheralded facts about America’s health care system.1. Americans have better survival rates than Europeans for common cancers.Breast cancer mortality is 52 percent higher in Germany than in the United States and 88 percent higher in the United Kingdom. Prostate cancer mortality is 604 percent higher in the United Kingdom and 457 percent higher in Norway. The mortality rate for colorectal cancer among British men and women is about 40 percent higher.2. Americans have lower cancer mortality rates than Canadians.Breast cancer mortality in Canada is 9 percent higher than in the United States, prostate cancer is 184 percent higher, and colon cancer among men is about 10 percent higher.3. Americans have better access to treatment for chronic diseases than patients in other developed countries. Some 56 percent of Americans who could benefit from statin drugs, which reduce cholesterol and protect against heart disease, are taking them. By comparison, of those patients who could benefit from these drugs, only 36 percent of the Dutch, 29 percent of the Swiss, 26 percent of Germans, 23 percent of Britons, and 17 percent of Italians receive them.

4. Americans have better access to preventive cancer screening than Canadians. Take the proportion of the appropriate-age population groups who have received recommended tests for breast, cervical, prostate, and colon cancer:

  • Nine out of ten middle-aged American women (89 percent) have had a mammogram, compared to fewer than three-fourths of Canadians (72 percent).
  • Nearly all American women (96 percent) have had a Pap smear, compared to fewer than 90 percent of Canadians.
  • More than half of American men (54 percent) have had a prostatespecific antigen (PSA) test, compared to fewer than one in six Canadians (16 percent).
  • Nearly one-third of Americans (30 percent) have had a colonoscopy, compared with fewer than one in twenty Canadians (5 percent).

5. Lower-income Americans are in better health than comparable Canadians. Twice as many American seniors with below-median incomes self-report “excellent” health (11.7 percent) compared to Canadian seniors (5.8 percent). Conversely, white, young Canadian adults with below-median incomes are 20 percent more likely than lower-income Americans to describe their health as “fair or poor.”

6. Americans spend less time waiting for care than patients in Canada and the United Kingdom. Canadian and British patients wait about twice as long—sometimes more than a year—to see a specialist, have elective surgery such as hip replacements, or get radiation treatment for cancer. All told, 827,429 people are waiting for some type of procedure in Canada. In Britain, nearly 1.8 million people are waiting for a hospital admission or outpatient treatment.

7. People in countries with more government control of health care are highly dissatisfied and believe reform is needed. More than 70 percent of German, Canadian, Australian, New Zealand, and British adults say their health system needs either “fundamental change” or “complete rebuilding.”

8. Americans are more satisfied with the care they receive than Canadians. When asked about their own health care instead of the “health care system,” more than half of Americans (51.3 percent) are very satisfied with their health care services, compared with only 41.5 percent of Canadians; a lower proportion of Americans are dissatisfied (6.8 percent) than Canadians (8.5 percent).

9. Americans have better access to important new technologies such as medical imaging than do patients in Canada or Britain. An overwhelming majority of leading American physicians identify computerized tomography (CT) and magnetic resonance imaging (MRI) as the most important medical innovations for improving patient care during the previous decade—even as economists and policy makers unfamiliar with actual medical practice decry these techniques as wasteful. The United States has thirty-four CT scanners per million Americans, compared to twelve in Canada and eight in Britain. The United States has almost twenty-seven MRI machines per million people compared to about six per million in Canada and Britain.

10. Americans are responsible for the vast majority of all health care innovations. The top five U.S. hospitals conduct more clinical trials than all the hospitals in any other developed country. Since the mid- 1970s, the Nobel Prize in medicine or physiology has gone to U.S. residents more often than recipients from all other countries combined. In only five of the past thirty-four years did a scientist living in the United States not win or share in the prize. Most important recent medical innovations were developed in the United States.

Despite serious challenges, such as escalating costs and care for the uninsured, the U.S. health care system compares favorably to those in other developed countries.

Researchers link rise in some cancers to increased sexual activity

From USA Today. (H/T Ruth Blog)

Excerpt:

Although the link between HPV and these types of cancers is indisputable, the association with oral sex is strong but a little more speculative, experts say.

A 2007 study in the New England Journal of Medicine found that younger people with head and neck cancers who tested positive for oral HPV infection were more likely to have had multiple vaginal and oral sex partners in their lifetime.

In the study, having six or more oral sex partners over a lifetime was associated with a 3.4 times higher risk for oropharyngeal cancer — cancers of the base of the tongue, back of the throat or tonsils. Having 26 or more vaginal-sex partners tripled the risk.

And the association increased as the number of partners — in either category — increased.

The researchers also reported that cancers of the tonsil and base of the tongue have been increasing every year since 1973, and wrote that “widespread oral sex practices among adolescents may be a contributing factor in this increase.”

The researchers concluded that in their study, oral sex was “strongly associated” with oropharyngeal cancer, but noted that they could not “rule out transmission through direct mouth-to-mouth contact” such as French kissing.

In 90% of cases of HPV infection in the body, the immune system clears HPV naturally within two years, according to federal health agencies, but in some cases, certain types of HPV can lead to cervical cancer or less common malignancies, such as oropharyngeal cancer. A 2010 Swedish study, in fact, suggested that the rise in oropharyngeal squamous cell cancer in a number of countries “is caused by a slow epidemic of HPV infection-induced (cancers).”

HPV tends to be site specific, explained Dr. Amesh A. Adalja, an adjunct instructor in the division of infectious diseases at the University of Pittsburgh Medical Center. In other words, it tends to stay wherever it first enters the body, be it the vagina (which in some cases could lead to cervical cancer), or the mouth and throat.

Now here is the scary part:

The U.S. Centers for Disease Control and Prevention (CDC) reports that, in 2002, some 90% of males and 88% of females aged 25 to 44 reported ever having oral sex with a partner of the opposite sex.

Comparable figures from 1992 showed that about three-quarters of men aged 20 to 39 and closer to 70% of women aged 18 to 59 having ever given or received oral sex.

And don’t forget that breast cancer has been linked to having abortions by several independent studies.
