Annual cancer screening tests urged less and less

AppId is over the quota
AppId is over the quota
Annual cancer tests are becoming a thing of the past. New guidelines out Wednesday for cervical cancer screening have experts at odds over some things, but they are united in the view that the common practice of getting a Pap test every year is too often and probably doing more harm than good.

A Pap smear once every three years is the best way to detect cervical cancer, the U.S. Preventive Services Task Force says. Last week, it recommended against prostate cancer screening with PSA tests, which many men get every year.

Two years ago, it said mammograms to check for breast cancer are only needed every other year starting at age 50, although the American Cancer Society still advises annual tests starting at age 40. Earlier this week, a large study found more false alarms for women getting mammograms every year instead of every other year.

"The more tests that you do, the more likely you are to be faced with a false-positive test" that leads to unnecessary biopsies and possible harm, said Dr. Michael LeFevre, one of the task force leaders and a professor of family and community medicine at the University of Missouri. "We see an emerging consensus that annual Pap tests are not required for us to see the benefits that we have seen" from screening, he said.

Those benefits are substantial. Cervical cancer has declined dramatically in the United States, from nearly 15 cases for every 100,000 women in 1975 to nearly 7 per 100,000 in 2008. About 12,200 new cases and 4,210 deaths from the disease occurred last year, most of them in women who have never been screened or not in the past five years.

New proposed guidelines from the cancer society and other groups say using Pap smears together with tests for HPV, the virus that causes cervical cancer, every three to five years is the preferred way to screen women ages 30 to 65. But the government task force concluded the evidence is insufficient "to assess the balance of benefits and harms" of that.

Instead, more lives probably could be saved by reaching women who are not being adequately screened now, the task force says.

And despite what many people suspect, cost has nothing to do with the task force's stance, its leaders said.

"We don't look at cost at all. We really are most concerned about harms," said Dr. Evelyn Whitlock of Kaiser Permanente Northwest's Center for Health Research in Portland, Ore., who led an evidence review for the task force.

Here are some questions and answers about the cervical cancer guidelines.

Q. At what ages should screening start and end?

A. The task force recommends against screening women under 21 or older than 65. Very few cervical cancer cases occur in women under 21, so the old advice to start screening three years after the age of first intercourse has been changed. HPV tests are only approved for women after age 30 because transient infections that don't pose a cancer risk are more common at younger ages.

"We should not be screening teenagers. It's not helping, it's not finding any more cancers and it's creating way too many harms for them," said Debbie Saslow, the cancer society's director of breast and gynecologic cancer.

Q. Should anyone else not be screened?

A. Women who have had their cervix and uterus removed should not be tested, but check with your doctor — not all hysterectomies are complete; some leave the cervix.

Q. What does screening cost?

A. Paps cost $15 to $60; HPV tests run $50 to $100.

Q. Will insurance pay for HPV tests since the government panel doesn't endorse them?

A. Probably. They are included in preventive services that other federal advisers say should be covered under the Affordable Care Act, and the government has continued to pay for mammograms for women who want them even if it is sooner or more often than the task force recommends.

Q. What if I've had the HPV vaccine?

A. Doctors don't know how the vaccine will affect HPV test results or how long the vaccine lasts, so women should still be screened for cervical cancer if they are within the recommended screening ages.

Q. How can I comment on the guidelines?

A. The web sites below tell how. Comments are accepted for a month before guidance is adopted.

More scans urged for unborn twins

AppId is over the quota
AppId is over the quota
28 September 2011 Last updated at 00:35 GMT By Helen Briggs Health editor, BBC News website Twin pregnancy at 32 weeks Twins in the womb at 32 weeks Women expecting twins or triplets should be offered closer monitoring, including extra scans, according to new NHS guidelines.

Health watchdog NICE has drawn up recommendations for antenatal care in multiple pregnancies, amid evidence standards vary in England and Wales.

Mothers-to-be should be referred to specialist teams and receive a minimum of six scans, says NICE.

Charities say the guidelines will give mothers reassurance about their care.

Multiple births are on the rise, due mainly to an increase in the number of couples having IVF. They now account for 3% of births.

Until now, there have been no clear guidelines for women expecting twins or triplets in England and Wales, leading to differences in care, including the number and timing of scans, planned delivery dates, and the use of measures, such as bed rest, to prevent early labour.

Dr Fergus Macbeth, director of the centre for clinical practice at The National Institute for Health and Clinical Excellence (NICE), said: "We know there is a real clinical need for this guideline because NHS antenatal care for women expecting twins or triplets appears to vary considerably across England and Wales.

"For example, not all women with multiple pregnancies are cared for in dedicated settings such as 'twin clinics' or by multidisciplinary teams of healthcare professionals.

"This can lead to higher than necessary rates of assisted birth and Caesarean sections and also means that women are not appropriately assessed for possible risks during pregnancy.

"Although many women will have a normal pregnancy and birth, it is well known that there are higher risks involved for these types of pregnancy and so it is important to get it right."

Multi-disciplinary approach

The guidance says women expecting twins or triplets should receive at least six scans, and sometimes as many as 11.

A scan should be carried out at between 11 and 14 weeks to assess whether twins share a placenta, which can increase the risk of complications.

NICE said women at risk of going into labour early should not be routinely offered bed rest or drugs to prevent labour as there was no evidence that they work.

They do not look at women who are pregnant with four or more babies.

Dr Virginia Beckett, from the Royal College of Obstetricians and Gynaecologists, welcomed the guidelines. She said increased monitoring and contact with healthcare workers would help ensure the mother and their babies received the best care possible.

"A multi-disciplinary approach including input from midwives, obstetricians and ultrasonographers will help ensure any complications are picked up early," she said.

Jane Denton, director of the Multiple Births Foundation, said: "Although much of the care at present is very good, there are many inconsistencies and often poor co-ordination between healthcare professionals if mothers are referred to other hospitals.

"These recommendations address all of these concerns and will give mothers confidence that they are receiving the highest standard of care, appropriate to their individual needs."
