Pelvic screening, another exam that does more harm than good
Pelvic
examination, another
screening bites the dust, along with PSA, thyroid, and mammograms. The harder they look the more likely the
non-cancer benign growth will be labeled carcinoma. A carcinoma by definition must invade
adjacent tissue; thus a local tumor is benign.
The risk of becoming malignant in the future is under 5% if under the
microscope the biopsy shows that the benign tumor cells are well
differentiated. Early detection
for the
above tumors has not in controlled studies showed to lower the mortality rate
compared to those who don’t undergo screening. And
it gets worse, for over half of all people
treated for breast, prostate, and thyroid cancers have benign tumors called
carcinomas. Too often treatment
is not
just limited to removal of the benign tumor but also chemotherapy for which the
clinic makes nearly half their income on the spread between what they bill
insurance and their discounted cost. The
chemotherapy and with chemical castration of those with breast and prostate cancers
entails that they shorten their live an average of at least 4 years compared to
those who don’t go through chemotherapy and castration.
And it gets worse, for clinical trials have
shown for men and women that hormone replacement therapy both reduces the
cancer risk and lowers the incidents of metastatic cancer after diagnosis (for
links to those journal articles men,
women). There is a modest
life extension for those
with metastatic cancers, but for all others castration shortens life and
increases risk of metastatic cancer. Many
of them suffer long-term from digestive-colon consequences of the treatment and
other under-reported side effects.
From journal full text (http://annals.org/article.aspx?articleid=1884537): “The
PLCO (Prostate, Lung, Colorectal and Ovarian) trial screened with bimanual
pelvic examination for 5 years, in addition to CA-125 and transvaginal
ultrasonography, and found no reduction in ovarian cancer (or other cancer)
mortality rates associated with the pelvic examination or the 3 methods
combined (11). No other studies assessed the benefits of pelvic examination for
reduction of ovarian cancer morbidity or mortality rates.” Although no
studies explicitly evaluated the
effect of the screening pelvic examination on nonovarian and noncervical cancer
morbidity or mortality rates, the PLCO trial did not report any reduction in
these outcomes, nor did cohort studies of pelvic examination to detect ovarian
cancer report detection of any nonovarian and noncervical cancer (11). No other studies assessed the benefits of pelvic examination on other
cancer.” And this quote does not considered the harm done by those treated with
benign tumors. Moreover there is there
is cost and other risks: “The evaluated
harms included fear, anxiety, embarrassment, pain, and discomfort. Physical
harms may include urinary tract infections and symptoms, such as dysuria and
frequent urination…. Women who
reported pain or discomfort during the pelvic examination ranged from 11% to
60% (median, 35%; 8 studies including 4576 participants), and 10% to 80%
reported fear, embarrassment, or anxiety (median, 34%; 7 studies including
10 702 participants). Women who experienced pain or discomfort during
their examination were less likely to have a return visit than those who did
not (5 out of 5 studies reporting this relationship). The evaluated harms included
false
reassurance, overdiagnosis, overtreatment, and diagnostic procedure–related
harms…. Evidence shows that the diagnostic accuracy of pelvic examination for
detecting ovarian cancer or bacterial vaginosis is low. The PLCO trial and cohort studies
suggest that the screening pelvic examination rarely detects noncervical cancer
or other treatable conditions and was not associated with improved health
outcomes.”

Value
of Screening Pelvic Exam for Women Debated
Lara C. Pullen, PhD, July 02, 2014
The American College of
Physicians (ACP) has issued new clinical guidelines recommending against
screening pelvic examination in asymptomatic, nonpregnant, adult women. The
college describes the recommendation as strong, with moderate-quality evidence.
Molly Cook, MD, a general
practitioner who served on the ACP Clinical Guidelines Committee, spoke with Medscape Medical News about
the new guidelines. She sees the
guidelines from the perspective of her role as a general practitioner and the
choices she must make during the limited time she has with patients: "That
20 minutes is really crowded, and I want to use my time in ways that are
particularly going to benefit women."
Pelvic examinations are
commonly used as a screen for pathology in asymptomatic, nonpregnant, adult
women. ACP has reviewed the literature and determined that the screening pelvic
examination does not benefit adult women. Although the recommendations advise
against pelvic examinations, the recommendation for Papanicolaou smears
remains.
Amir Qaseem, MD, PhD, from the
American College of Physicians, Philadelphia, Pennsylvania, and colleagues
developed the guidelines for the Clinical Guidelines Committee of the ACP. The
guidelines were published
online July 1
in theAnnals of Internal Medicine.
The authors reviewed the
evidence and found that the harms associated with screening pelvic examination
outweigh the benefits. The guidelines also explain that screening for chlamydia
and gonorrhoea, sometimes done by pelvic examination, can be reliably performed
using nucleic acid amplification tests on self-collected vaginal swabs or
urine. “[N]ucleic acid amplification tests on self-collected vaginal swabs or
urine have been shown to be highly specific and sensitive, and this technique
is supported by several organizations,” the authors write.
In their recommendation, they
add, "With the available evidence, we conclude that screening pelvic
examination exposes women to unnecessary and avoidable harms with no benefit
(reduced mortality or morbidity rates). In addition, these examinations add
unnecessary costs to the health care system ($2.6 billion in the United
States). These costs may be amplified by expenses incurred by additional
follow-up tests, including follow-up tests as a result of false-positive
screening results; increased medical visits; and costs of keeping or obtaining
health insurance."
Robert Morgan, MD, codirector
of the Gynecological Cancers Program at City of Hope in Duarte, California, is
uncomfortable with the new guidelines, and expressed his discomfort in an
interview with Medscape Medical News. He acknowledged up front that he
is a medical oncologist and that his specialty colors his viewpoint and drives
his desire to continue to screen for cancer. "I am really concerned that
in 10 years, we are going to see people who have put off their routine
[Papanicolaou] smears," he explains.
The American College of
Obstetricians and Gynecologists (ACOG) also has reservations about the ACP
clinical guidelines. In a press release, ACOG states that it stands by its
current guidelines for well-women visits, which includes pelvic examinations.
The college believes the choice to perform pelvic examinations is one that
should be made on the basis of a woman's individual needs, requests, and
preferences.
ACOG believes that an annual
pelvic examination remains a useful tool, in particular for the recognition of
incontinence and sexual dysfunction. The college also emphasizes the importance
of other aspects of the well-woman visit, including clinical breast
examination, immunizations, and contraceptive discussion.
"We continue to urge women
to visit their health care providers for annual visits, which play a valuable
role in patient care," said John C. Jennings, MD, president of ACOG, in a
news release. "An annual well-woman visit can help physicians to promote
healthy living and preventive care, to evaluate patients for risk factors for
medical conditions, and to identify existing medical conditions, thereby
opening the door for treatment. Annual well-woman visits are important for
quality care of women and their continued health."

and other support from Healthwise. The other authors, Dr. Cook, and Dr. Morgan
have disclosed no relevant financial relationships.
