The U.S.
Preventive Services Task Force today released a draft recommendation statement
and evidence review on ovarian cancer screening that is in line with its final
recommendation in 2012.
The USPSTF
has given a ‘D’ grade for screening recommendation for ovarian cancer in asymptomatic
women, that means “The USPSTF recommends against screening for ovarian cancer
in asymptomatic women.”
The USPSTF
found adequate evidence that screening with transvaginal ultrasound, testing
for the serum tumor marker cancer antigen (CA)–125, or a combination of both
does not reduce the number of deaths from ovarian cancer in women.
The current
evidence was insufficient to assess the balance of benefits and harms of
performing screening pelvic examination in asymptomatic, nonpregnant adult
women.
The
screening tests also have a low positive predictive value, which means that
most women who receive a positive diagnosis of ovarian cancer do not have one.
It also
leads to unnecessary surgery and psychological harm.
This
screening guidelines are not for women with BRCA 1 and BRCA2 mutation, Lynch,
Li-Fraumeni, or Peutz-Jeghers syndrome. Women with BRCA1 and BRCA2 mutations
have an average risk of 44% and 17% for developing ovarian cancer. Mutations in
BRCA1 and BRCA2 account for around 15 percent of ovarian cancers.
USPSTF also
does not advice routine screening in women with family history breast and ovarian
cancer, as a higher incidence of cancer incidence in family may results in
greater number of patients diagnosed with ovarian cancer but it does not necessary
translate into saving lives.
These women
can be referred for genetic counseling and, if indicated,
genetic testing.
USPSTF chair
David Grossman, MD, MPH, senior investigator at Kaiser Permanente Washington
Health Research Institute, said in a statement, “The current screening tests do
not do a good job of identifying whether a woman does or does not have ovarian
cancer. The Task Force hopes that in the future, better screening tests for
ovarian cancer will be developed.”
The draft
recommendation was supported by results of two large clinical trials United
Kingdom Collaborative Trial of Ovarian Cancer Screening (UKCTOCS) and Prostate,
Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial which both showed
that screening for ovarian cancer does not decrease deaths from ovarian cancer
in asymptomatic women not known to be at high risk for ovarian cancer.
The recent
draft recommendation is in consensus with guidelines issued by other major
medical and public health organizations like American College of Obstetricians
and Gynecologists, American Cancer Society, American College of Radiology and American
Academy of Family Physicians.
The draft
recommendation statement is open to public comments till August 14, 2017.
